Understanding the Filet Mignon Cut

Before you light the grill, it is helpful to understand exactly what makes the filet mignon so special. The name itself is French, where "filet" means a thick slice and "mignon" means dainty or small. This cut is taken from the small end of the tenderloin, a muscle that runs along the spine of the steer.

Because the tenderloin is a non-weight-bearing muscle, it does very little work throughout the animal's life. This lack of exercise results in a muscle with incredibly fine fibers and very little connective tissue, which is why the filet mignon is famously tender—often described as "butter-knife tender." However, because it is so lean, it lacks the heavy fat caps found on a Boneless Ribeye (Prime, 16 oz). This means the flavor of a filet is more subtle and refined, making the quality of the sourcing and the precision of the cook even more vital.

When you browse our Shop, you will notice that the filet is prized for its lean profile. This leanness is exactly why many chefs prefer to cook it to medium-rare; without much fat to render, overcooking a filet quickly leads to a dry, metallic-tasting piece of meat. Understanding the anatomy of the cut helps you appreciate why high heat for a short duration is the preferred method for this particular steak.

Section Summary: The filet mignon is derived from the tenderloin, a muscle known for its extreme tenderness due to low activity. Its lean nature requires precise temperature control to maintain its signature buttery texture.

Selecting Your Steak

Success on the grill begins at the butcher block. When you are looking for the ideal candidate for grilling, thickness is your best friend. A thin steak will overcook in the center before you can develop a proper crust on the outside.

Ideal Thickness and Appearance

For the best results, look for steaks that are at least 1.5 to 2 inches thick. This thickness allows you to sear the exterior at high temperatures while keeping the internal temperature in that perfect medium-rare window. A well-cut steak, like our Filet Mignon (10 oz) or the Filet Mignon (8 oz), should appear plump, deep red, and firm to the touch. Avoid steaks that look grayish or show signs of "leaking" excessive moisture in the packaging, as this can indicate the meat has been frozen and thawed poorly or is not fresh.

Marbling and Sourcing

While the filet is a lean cut, you still want to see fine flecks of white fat within the muscle—this is known as marbling. These tiny deposits of intramuscular fat melt during the cooking process, providing moisture and flavor from the inside out. We recommend choosing steaks that are grass-fed and finished for a more robust, natural beef flavor. Sourcing matters immensely; knowing your beef comes from producers who avoid synthetic hormones and prioritize animal welfare ensures a cleaner, more premium taste.

Bone-In vs. Boneless

While the classic filet is boneless, some enthusiasts prefer the Bone-In Filet Mignon (14 oz). The bone acts as an insulator, slowing the cook near the center and often imparting a deeper, more "primal" flavor to the meat. If you are looking for a showstopper for a special occasion, the bone-in version provides a stunning visual presentation and a slightly different cooking dynamic that rewards the patient griller.

Section Summary: Choose steaks that are 1.5–2 inches thick with visible marbling and a deep red color. High-quality sourcing and appropriate thickness are the foundation of a successful grill session.

Preparing the Steak for the Grill

Once you have secured your premium cuts from our Beef Collection, the preparation phase begins. This is where you set the stage for a uniform cook and a flavorful crust.

The Importance of Tempering

One of the most common mistakes home cooks make is taking a steak directly from the cold refrigerator to a hot grill. This "thermal shock" causes the muscle fibers to tense up and results in a steak that is charred on the outside but still cold or raw in the center.

Remove your filets from the refrigerator approximately 30 to 60 minutes before you plan to cook. This allows the internal temperature of the meat to rise slightly, ensuring it cooks more evenly. During this time, pat the steaks dry with paper towels. Moisture is the enemy of a good sear; if the surface of the meat is wet, it will steam rather than brown.

Seasoning Techniques

Because the filet mignon has a delicate flavor, you don't need to overcomplicate the seasoning. A generous coating of kosher salt and freshly cracked black pepper is often all that is required.

• Salt: Use a coarse salt. The grains help create a textured crust and draw out just enough moisture to dissolve the salt, which is then reabsorbed into the meat, seasoning it deeply.
• Oil: Lightly brush the steaks with a high-smoke-point oil, such as grapeseed or avocado oil, or even a bit of melted bacon fat. This acts as a binder for the seasoning and helps the heat transfer efficiently from the grill grates to the meat.
• Herbs: If you want to add an aromatic touch, finely minced rosemary or thyme can be pressed into the surface of the steak along with the salt and pepper.

Dry Brining

If you have the time, you can salt your steaks and leave them uncovered in the fridge for a few hours (or even overnight). This "dry brine" allows the salt to penetrate deep into the muscle and dries out the exterior surface perfectly, leading to an incredible crust. Just remember to take them out to reach room temperature before they hit the flames.

Section Summary: Temper steaks at room temperature for up to an hour and pat them dry. Season simply with salt and pepper, using a light coat of oil to facilitate the sear.

The Grilling Environment

To understand how to grill a medium rare filet mignon, you must first understand your equipment. Whether you use gas or charcoal, the goal is the same: creating two distinct heat zones.

Gas Grills: Convenience and Control

Gas grills are excellent for their quick startup and precise temperature management. To prepare a gas grill:

1. Clean the Grates: Heat the grill to high and scrub the grates with a sturdy brush to remove any carbon buildup.
2. Preheat: Close the lid and let the temperature reach at least 500°F.
3. Two-Zone Setup: Turn one side of the burners to high and the other side to low or off. This creates a "sear zone" and a "safe zone."

Charcoal Grills: Smoke and Intensity

Many purists prefer charcoal for the distinct smoky aroma it imparts.

1. Direct vs. Indirect: Arrange your coals on one side of the grill. This creates a high-heat area for searing and a cooler area for finishing the steak without burning the exterior.
2. Airflow: Use the vents to control the temperature. More oxygen means a hotter fire. Wait until the coals are covered in a light gray ash before placing your meat on the grates.

The Two-Zone Method

This is the secret to restaurant-quality steak. You start the steak over direct heat to get those beautiful grill marks and the Maillard reaction (the chemical reaction between amino acids and reducing sugars that gives browned food its distinctive flavor). If the steak isn't at your target temperature by the time it’s perfectly browned, you move it to the indirect, cooler side to finish. This prevents the outside from becoming bitter or burnt while the inside reaches the perfect 130°F to 135°F.

Section Summary: Use a two-zone heat setup on either a gas or charcoal grill. High heat is for searing, while a cooler zone allows the steak to reach its internal target temperature without burning.

How to Grill a Medium Rare Filet Mignon: Step-by-Step

Now, let's walk through the actual process of the cook. This method focuses on achieving a medium-rare finish, which is the gold standard for tenderloin.

Step 1: The Initial Sear

Place your seasoned, room-temperature filets directly over the hottest part of the grill. You should hear a satisfying sizzle immediately. Press down lightly with tongs to ensure good contact with the grates. Close the lid—this helps maintain a consistent ambient temperature and prevents flare-ups.

Step 2: The Flip

For a steak that is 2 inches thick, sear for about 3 to 4 minutes on the first side. Do not move it around; let it develop a crust. Flip the steak. You should see deep, caramelized grill marks. Sear the second side for another 3 to 4 minutes.

Step 3: Checking Temperature

This is the most critical part of how to grill a medium rare filet mignon. Use an instant-read digital thermometer. Insert it into the thickest part of the steak, ideally through the side to get a reading from the very center.

• For Medium-Rare: You are aiming for a final temperature of 130°F to 135°F.
• The Pull Temp: Because of carryover cooking, you should remove the steak from the grill when it hits 125°F to 128°F.

Step 4: Using the Indirect Zone

If your steak has a perfect crust but the internal temperature is only 110°F, move it to the cooler side of the grill. Close the lid and let it roast gently until it reaches the pull temperature. This "sear and slide" method ensures the meat remains juicy.

Step 5: The Edges

Don't forget the sides! If your filet is particularly thick, use your tongs to stand the steak on its side and roll the edges across the hot grates for 30 seconds. This renders any small bits of surface fat and ensures the seasoning is toasted all the way around.

Section Summary: Sear for 3–4 minutes per side over direct heat. Use an instant-read thermometer and pull the steak off the grill at 125°F–128°F to account for carryover cooking.

Temperature Control and Doneness

While our focus is medium-rare, it is helpful to understand the full spectrum of doneness so you can cater to all your guests' preferences. Each level of doneness changes the texture and flavor profile of the beef.

Doneness	Pull Temp (Off Grill)	Final Temp (After Rest)	Center Appearance
Rare	115°F - 120°F	120°F - 125°F	Cool, bright red
Medium-Rare	125°F - 128°F	130°F - 135°F	Warm, ruby red
Medium	135°F - 140°F	140°F - 145°F	Warm, pink throughout
Medium-Well	145°F - 150°F	150°F - 155°F	Slightly pink center
Well Done	155°F+	160°F+	Mostly brown/gray

Why Medium-Rare?

For a cut like the filet mignon, medium-rare is widely considered the peak of flavor and texture. At 130°F, the proteins have just begun to firm up, but the moisture is still held tightly within the fibers. The result is a steak that is incredibly succulent. If you prefer a bit more "chew" and a more rendered fat profile, you might enjoy a 36 Ounce Porterhouse, which includes both a filet and a New York strip, allowing you to experience different textures in one cook.

The Touch Test vs. The Thermometer

You may have heard of the "finger test" (comparing the firmness of the steak to the fleshy part of your palm). While this can be a helpful backup for experienced grillers, it is notoriously unreliable due to differences in steak thickness and hand anatomy. To guarantee results when learning how to grill a medium rare filet mignon, always rely on a high-quality digital thermometer.

Section Summary: Medium-rare is reached at a final temperature of 130°F–135°F. Always use a thermometer for accuracy, pulling the meat slightly early to account for the temperature rise during the rest.

The Art of Resting and Slicing

The most difficult part of grilling a perfect steak is the ten minutes after you take it off the heat. You must let it rest.

Why Resting is Non-Negotiable

While the steak is on the grill, the heat causes the muscle fibers to contract, pushing the juices toward the center of the meat. If you cut into the steak immediately, those juices will pour out onto your plate, leaving the meat dry and tough. By resting the steak on a warm plate or cutting board for 5 to 10 minutes, you allow the muscle fibers to relax and reabsorb the moisture. This ensures that every drop of flavor stays inside the meat where it belongs.

Carryover Cooking

As mentioned earlier, the internal temperature will continue to rise by 5 to 7 degrees after being removed from the grill. This is why pulling the meat at 125°F is essential for a 130°F-135°F finish. If you wait until the thermometer reads 135°F on the grill, your steak will likely end up at a "medium" level of doneness (140°F+) by the time you eat it.

Slicing for Success

Filet mignon is already incredibly tender, but you can maximize that quality by slicing against the grain. Look for the direction the muscle fibers are running and cut perpendicular to them. For a filet, the fibers usually run vertically, so horizontal slices across the "face" of the steak are standard.

Section Summary: Rest the steak for at least 5–10 minutes to allow juices to redistribute. Carryover cooking will raise the temperature by several degrees, so pull the steak early.

Flavor Enhancements: Rubs and Butters

While salt and pepper are the classics, a few additions can take your grilled filet to the next level. Since the filet is lean, adding a hit of fat at the end is a common steakhouse trick.

Compound Butters

A slice of herb-infused butter melting over a hot steak creates a luxurious sauce.

• Garlic and Herb: Mix softened butter with minced garlic, parsley, and a splash of lemon juice.
• Blue Cheese: For a sharper flavor, fold crumbles of gorgonzola or stilton into the butter. This provides a beautiful contrast to the mildness of the beef. Apply the butter during the last minute of resting so it creates a glaze rather than just melting off.

Board Sauces

Instead of a traditional sauce, try a "board sauce." While the steak rests, chop some fresh herbs (chimichurri style), garlic, and a little olive oil directly on your cutting board. When you slice the steak, the juices will mingle with the herbs on the board, creating a fresh, instant sauce that coats every piece.

Alternative Cuts for Comparison

If you enjoy the process of grilling but want a more intense, beefy flavor, you might occasionally swap the filet for a Wagyu Flat Iron or an Outside Skirt Steak (8 oz). These cuts have more fat and connective tissue, offering a different but equally delicious grilling experience.

Section Summary: Enhance your filet with compound butters or board sauces to add moisture and complexity. Adding fat at the end complements the leanness of the tenderloin.

Perfect Pairings for a Steakhouse Experience

A perfect medium-rare filet mignon deserves side dishes that complement its elegance without overshadowing it. When planning your menu, think about balancing the rich, savory notes of the beef with acidity or creaminess.

Classic Potato Pairings

• Garlic Mashed Potatoes: The creamy texture of well-whipped potatoes is the traditional partner for a tender filet.
• Duck Fat Fries: For a more modern approach, the crispiness of fries provides a great textural contrast to the soft meat.
• Roasted Fingerlings: Tossing small potatoes in rosemary and sea salt echoes the seasonings on the steak.

Vegetable Sides

• Grilled Asparagus: You already have the grill hot, so toss some asparagus stalks in olive oil and salt and char them for 3-4 minutes.
• Creamed Spinach: A steakhouse staple that adds a rich, velvety element to the plate.
• Balsamic Glazed Brussels Sprouts: The acidity of the balsamic vinegar cuts through the richness of the beef.

Surf and Turf Inspiration

To truly elevate your meal, consider adding a seafood element from our Home Delivery service. A grilled lobster tail or a few jumbo sea scallops turned into a "surf and turf" platter makes any dinner feel like a five-star event. The sweetness of the seafood pairs beautifully with the savory depth of a Boneless New York Strip Steak (14 oz) or your perfectly grilled filet.

Section Summary: Balance your meal with creamy or acidic sides like mashed potatoes or balsamic Brussels sprouts. Consider adding seafood for a premium surf and turf experience.

Storage and Food Safety

When handling premium meats, safety and proper storage are paramount to preserve the quality you’ve invested in.

• Refrigeration: Fresh beef should be kept in the coldest part of your refrigerator (usually the back of the bottom shelf) and cooked within 3 to 5 days of purchase.
• Freezing: If you aren't ready to cook your Beef Collection items immediately, they can be frozen. To prevent freezer burn, ensure they are vacuum-sealed or tightly wrapped in plastic wrap and then placed in a heavy-duty freezer bag.
• Thawing: Never thaw steaks on the counter. The safest method is to move them to the refrigerator 24 hours before cooking. For a quicker thaw, place the sealed package in a bowl of cold water, changing the water every 30 minutes.
• Leftovers: If you happen to have leftover steak, it can be stored in an airtight container for up to 3 days. To reheat, do so gently in a low-temperature oven (250°F) until just warm to avoid overcooking the medium-rare center you worked so hard to achieve.

Section Summary: Store fresh meat in the coldest part of the fridge and thaw slowly in the refrigerator. Reheat leftovers gently to preserve the medium-rare texture.

FAQ

How long does it take to grill a filet mignon to medium-rare?

On a grill set to 450°F–500°F, a 2-inch thick filet mignon typically takes about 8 to 12 minutes total. This usually involves 4 minutes of searing on the first side and 4 to 6 minutes on the second side, depending on the exact thickness and the grill's heat consistency. Always use a thermometer rather than a timer for the best results.

Should I grill filet mignon with the lid open or closed?

For thick cuts like filet mignon, it is generally best to keep the lid closed as much as possible. This creates an oven-like environment that cooks the steak from all sides, ensuring the center reaches the target temperature without the exterior burning. Only open the lid to flip the steak or check the temperature.

How do I prevent the steak from sticking to the grill?

There are three secrets to prevent sticking: ensure your grill grates are very clean, make sure the steak is patted dry before seasoning, and lightly oil the steak (not the grates). Additionally, do not try to flip the steak too early. When the meat has developed a proper sear, it will naturally release from the grates.

Can I grill a filet mignon that was previously frozen?

Yes, as long as it was thawed properly. The best way to thaw a steak is slowly in the refrigerator over 24 hours. This preserves the cell structure of the meat, ensuring it stays juicy. Once thawed, follow the same steps: temper to room temperature, pat dry, and season.

What is the difference between a filet mignon and a ribeye on the grill?

A filet mignon is leaner and more tender, requiring a more delicate touch and shorter cook time. A Bone-In Ribeye (22 oz) has significantly more fat and marbling, which allows it to withstand higher heat for longer and provides a more intense, "beefy" flavor. Filet is chosen for its texture, while ribeye is chosen for its richness.

Is it necessary to use a meat thermometer?

While experienced chefs can sometimes tell doneness by touch, a digital meat thermometer is the only way to guarantee a perfect medium-rare every time. Given that filet mignon is a premium investment, using a thermometer is the best way to ensure you don't overcook the meat.
