We believe that exceptional meals start with exceptional ingredients, and we are here to empower you to create restaurant-quality experiences at home.

The journey from the ocean to your table involves careful handling and expert knowledge. Let’s begin by exploring what makes a tuna steak worthy of a sesame crust and how you can ensure every bite is succulent, flavorful, and perfectly cooked.

Selecting the Best Quality Tuna

Before you even turn on the stove, the success of your meal is determined by the quality of the fish. Because tuna steaks are traditionally served rare or medium-rare, the freshness and grade of the seafood are paramount. Using inferior fish not only compromises flavor but also raises safety concerns when consuming it undercooked.

Understanding Saku and Sushi-Grade

When searching for tuna, you will often encounter terms like "sushi-grade" or "sashimi-grade." While these are not official USDA regulated terms, they indicate that the fish has been handled and frozen specifically to be safe for raw consumption. One of the most sought-after cuts for a sesame-crusted dish is the Saku block. "Saku" means "block" in Japanese, and it typically refers to a uniform, rectangular cut of tuna that has been deboned and deskinned. This shape is ideal for even searing and provides those beautiful, uniform slices you see in professional photography.

For the best results, look for Hawaiian Tuna or premium Yellowfin options. These varieties offer a firm, "meaty" texture that holds up well against the high heat of a skillet. At Land and Sea Delivery, we pride ourselves on providing access to the same high-caliber seafood used by top-tier restaurants through our Seafood Collection.

Fresh vs. Frozen: The Flash-Freeze Advantage

There is a common misconception that "fresh" is always superior to "frozen." In the world of high-end tuna, flash-freezing is actually a mark of quality. When tuna is frozen immediately after being caught, it locks in the texture and flavor while eliminating potential parasites. This makes it incredibly safe for the quick searing required for this recipe. When you order from our Shop, you are getting products that have been handled with the utmost care to ensure the integrity of the protein remains intact from the moment it leaves the water.

What to Look for Visually

If you are selecting your tuna in person or inspecting your delivery, look for a deep, vibrant red or pinkish-purple color. Avoid any steaks that appear brown or "dull," as this is a sign of oxidation. The meat should feel firm to the touch and have a clean, oceanic scent—never a "fishy" or ammonia-like odor. A premium steak like our Wild Caught Swordfish or Alaskan Halibut shares these qualities of freshness, but for this specific sesame application, the density of Ahi or Yellowfin is unmatched.

Summary: The foundation of a great sesame-crusted tuna is the fish itself. Prioritize sushi-grade Saku blocks or premium Ahi for safety and uniform cooking. Remember that high-quality frozen tuna is often safer and fresher than "never frozen" options that have spent days in transit.

Essential Preparation Steps

Once you have your premium tuna from Land and Sea Delivery, the preparation phase is what ensures your sesame seeds stick and your crust becomes crispy rather than gummy.

The Thawing Process

If your tuna is frozen, the best way to thaw it is slowly in the refrigerator overnight. This preserves the cellular structure of the meat. If you are in a hurry, you can place the vacuum-sealed tuna in a bowl of cold water for about 30 to 45 minutes. Never use warm water or a microwave, as this will begin to "cook" the delicate proteins and ruin the texture.

The Importance of a Dry Surface

This is perhaps the most critical tip for any pan-searing task. Moisture is the enemy of a good sear. If there is water on the surface of the fish, it will create steam when it hits the hot oil. Steam prevents the "Maillard reaction"—the chemical process that creates a browned, flavorful crust. Use paper towels to pat the tuna steak completely dry on all sides until no moisture remains.

Choosing Your Binder

To get the sesame seeds to adhere to the fish, you need a "binder." While some recipes use oil, a splash of soy sauce or tamari is highly recommended. The salt in the soy sauce seasons the fish, while the natural sugars help with caramelization. Simply brush a light coating over the entire steak. If you prefer a gluten-free option, liquid aminos or tamari work perfectly.

Tempering the Meat

Take your tuna out of the refrigerator about 15 to 20 minutes before cooking. If the center of the steak is ice-cold when it hits the pan, the outside will burn before the inside reaches a palatable temperature. Bringing it closer to room temperature ensures a more even heat distribution during those brief seconds in the pan.

Summary: Proper preparation involves slow thawing, meticulous drying of the fish, and using a flavorful binder like soy sauce. Allowing the meat to temper for a few minutes ensures a better sear and a more consistent internal temperature.

Crafting the Perfect Sesame Crust

The crust is what gives this dish its name and its signature crunch. A simple pile of sesame seeds is a good start, but a truly professional crust involves a few extra layers of flavor.

Black vs. White Sesame Seeds

Using a mixture of both black and white sesame seeds is visually stunning. The black seeds provide a deep, earthy aesthetic, while the white seeds show the progress of the toastiness. Beyond aesthetics, the seeds provide a nutty flavor that cuts through the richness of the tuna.

Adding "The Secret Ingredient": Sugar

Professional chefs often add a tiny pinch of granulated sugar to their sesame seed mix. Why? Because tuna sears so quickly (often in less than 60 seconds), the sugar helps the seeds and the surface of the fish caramelize almost instantly. This gives you a deep golden color without overcooking the interior of the steak.

Spice Enhancements

To take your crust to the next level, consider mixing the seeds with:

• Garlic or Onion Powder: For a savory depth.
• Dried Thyme or Ginger: To add an aromatic or spicy note.
• Coarse Salt and Cracked Black Pepper: Essential for bringing out the natural flavors of the tuna.
• Crushed Red Pepper: If you prefer a bit of heat.

How to Apply the Coating

Spread your sesame seed mixture onto a flat plate. Press each side of the tuna steak firmly into the seeds. Don't forget the edges! Use your fingers to pack the seeds onto the sides of the steak. You want a "wall-to-wall" coating that acts as a protective, flavorful barrier between the heat and the delicate fish.

Summary: A great crust uses a blend of black and white seeds for visual appeal and flavor. A touch of sugar aids in rapid caramelization, while spices like garlic powder add complexity. Ensure the steak is fully encrusted on all sides for the best texture.

Mastering the Sear: Heat and Timing

This is the moment of truth. Learning how to cook tuna steak with sesame seeds requires confidence and high heat. This is not a "low and slow" process; it is a sprint.

The Right Pan

A cast-iron skillet is the gold standard for searing tuna. Cast iron retains heat better than almost any other material, meaning the temperature won't drop when the fish hits the pan. If you don't have cast iron, a heavy-bottomed stainless steel pan will work. Avoid non-stick pans if possible, as the extremely high heat required can sometimes damage the non-stick coating and won't produce the same level of crust.

Selecting Your Oil

You need an oil with a high smoke point. Extra virgin olive oil or butter will burn and turn bitter at the temperatures required for this sear. Instead, choose:

• Avocado Oil: Very high smoke point and neutral flavor.
• Peanut Oil: Adds a subtle nuttiness that complements the sesame.
• Grapeseed Oil: A clean, high-heat option.

The "Shimmer" Test

Heat your skillet over medium-high to high heat. You want the pan to be "ripping hot." Add your oil and wait for it to shimmer or just begin to show a tiny wisp of smoke. A flick of water should sizzle and evaporate instantly.

The Cooking Process

1. Place the Steak: Carefully lay the tuna into the pan. It should sizzle loudly.
2. The First Side: Sear for 30 to 60 seconds. Do not move the steak! Let it sit so the crust can form.
3. The Flip: Use tongs or a metal spatula to flip the steak. Sear the other side for another 30 to 60 seconds.
4. The Edges: Use tongs to hold the steak upright and sear the edges for 15 to 20 seconds each. This ensures no part of the exterior remains raw.

The goal is to have a crust that is golden brown and seeds that are toasted, while the center remains a beautiful, cool pink or red.

Summary: Use a cast-iron skillet and high-smoke-point oil. The pan must be extremely hot. Sear each side for less than a minute to maintain a rare center while achieving a crisp, toasted sesame exterior.

Understanding Doneness and Temperatures

While many enjoy their tuna rare, personal preference varies. However, tuna is a lean fish, and overcooking it can result in a dry, "canned" texture that loses the buttery mouthfeel of a premium cut.

The Doneness Scale

• Rare: Seared for about 30-45 seconds per side. The center is cool and bright red. Internal temperature: 115°F - 120°F.
• Medium-Rare: Seared for 60-90 seconds per side. The center is warm and pink. Internal temperature: 125°F - 130°F.
• Medium: Seared for about 2 minutes per side. The pink center is much smaller. Internal temperature: 135°F - 140°F.
• Well-Done: Not recommended for high-quality tuna, as it becomes very dry. If desired, cook until the internal temperature reaches 145°F or higher.

Using a Thermometer

While the "visual check" of the side of the steak is usually enough for experienced cooks, using a digital meat thermometer can help beginners. Insert it into the thickest part of the steak. Keep in mind that "carry-over cooking" will occur—the temperature will rise by about 5 degrees after you remove it from the pan.

Resting the Fish

Just like a beef steak, tuna needs to rest. Let it sit on a cutting board for 2 to 3 minutes before slicing. This allows the juices to redistribute, ensuring that your first slice doesn't result in all the moisture running out onto the board.

Summary: Rare to medium-rare is the ideal doneness for sesame-crusted tuna to preserve its texture. Use a thermometer for precision, and always allow the fish to rest for a few minutes before slicing to keep it juicy.

Expert Slicing and Presentation

You have done the hard work of cooking; now it is time to make it look like a plate from a five-star restaurant. Presentation is a key part of the Land and Sea Delivery experience—we believe food should be as beautiful as it is delicious.

The Right Knife

You need your sharpest knife—ideally a long, thin slicing knife or a chef’s knife. If your knife is dull, it will tear the delicate fibers of the tuna and knock off your beautiful sesame crust.

The Angle of the Cut

Slice the tuna against the grain into 1/4-inch to 1/2-inch thick pieces. Slicing on a slight diagonal (a bias cut) creates more surface area for the interior to show, which looks stunning against the dark crust.

Arrangement

Fan the slices out on a plate to showcase the contrast between the toasted seeds and the vibrant interior. This is the perfect time to add a garnish, such as:

• Microgreens or Scallions: For a pop of green.
• Pickled Ginger: For a traditional sushi-bar feel.
• Wasabi Paste: For those who enjoy a bit of nasal heat.

Summary: Use a very sharp knife to slice the rested tuna on a bias. Fanning the slices on the plate creates a professional, appetizing look that highlights the contrast between the crust and the rare center.

Creating the Perfect Dipping Sauce

A sesame-crusted tuna steak is delicious on its own, but a well-paired sauce brings the whole dish together. The goal is to provide acidity and saltiness to balance the "meaty" richness of the fish.

The Classic Soy-Ginger Sauce

This is the most common accompaniment. It is simple to whisk together while your tuna is resting:

• Base: 1/4 cup Soy Sauce or Tamari.
• Acidity: 2 tablespoons Rice Wine Vinegar.
• Sweetness: 1 tablespoon Honey or Mirin.
• Aromatics: 1 teaspoon freshly grated Ginger and a clove of minced Garlic.
• Heat: A dash of Sriracha or chili oil.

The Wasabi Cream Option

If you prefer something creamy, mix wasabi paste with a little bit of Greek yogurt or mayonnaise and a squeeze of lime juice. This provides a cool, sharp contrast that works beautifully with the toasted seeds.

Citrus-Forward Ponzu

For a lighter, more refreshing feel, a Ponzu sauce (soy sauce with citrus juices like yuzu or lemon) is an excellent choice. It highlights the freshness of Hawaiian Tuna without masking its natural flavor.

Summary: A dipping sauce should offer a balance of salt, acid, and heat. Whether you go with a traditional soy-ginger blend or a creamy wasabi sauce, it adds the final layer of professional flavor to your meal.

Serving Suggestions and Pairings

To turn your tuna steak into a complete meal, you need the right side dishes. You want accompaniments that are light and won't overshadow the star of the show.

Complementary Side Dishes

• Asian Cucumber Salad: Thinly sliced cucumbers with rice vinegar, sesame oil, and a pinch of sugar provide a cool, crunchy contrast.
• Sushi Rice: A bowl of seasoned, sticky rice makes the meal more substantial.
• Blistered Shishito Peppers: A quick sear in the same pan you used for the tuna adds a smoky, earthy element.
• Seaweed Salad: For an authentic Japanese-inspired experience.

Surf and Turf Inspiration

If you are looking to create a grand feast, consider a "Surf and Turf" pairing. While tuna is the star here, you could serve smaller portions of seared tuna alongside our premium meats or even other seafood like South African Lobster Tails or Jumbo Alaskan King Crab Legs.

Beverage Pairings

• White Wine: A crisp Sauvignon Blanc or a dry Riesling has the acidity to cut through the oils of the tuna.
• Red Wine: Surprisingly, a light-bodied Pinot Noir is a classic pairing for tuna because of its low tannins and red fruit notes.
• Non-Alcoholic: A sparkling water with a twist of lime or a chilled green tea works wonderfully.

Summary: Pair your tuna with light, acid-forward sides like cucumber salad or seaweed. For a more indulgent meal, consider adding lobster or crab from our Seafood Collection.

Safety, Storage, and Handling

Handling premium seafood requires respect for food safety and a basic understanding of how to store your ingredients properly.

Storage Before Cooking

Keep your tuna in the coldest part of your refrigerator until you are ready to temper it. It should be used within 1-2 days of purchase if fresh, or kept in the freezer until you are ready to follow our thawing guidelines. At Land and Sea Delivery, we ensure our Home Delivery service gets your order to you in peak condition.

Handling Leftovers

While seared tuna is best enjoyed immediately, leftovers can be kept in an airtight container in the refrigerator for up to two days. Note that the sesame crust will lose its crunch over time. Leftover tuna is excellent when served cold over a salad or tucked into a "sushi burrito." We do not recommend reheating seared tuna, as it will inevitably overcook the center and change the texture from succulent to rubbery.

Mercury Awareness

Tuna is a large predatory fish and contains mercury. While it is a healthy source of lean protein and Omega-3 fatty acids, it is generally recommended to enjoy it as a special treat rather than a daily staple. Balancing your diet with other options like Yellow Lake Perch Filets, Tilapia, or Cod is a great way to enjoy the variety of the ocean.

Summary: Store tuna in the coldest part of the fridge and use it promptly. Enjoy leftovers cold to preserve the texture, and vary your seafood intake by exploring the many options available in our Seafood Collection.

FAQ

Is it safe to eat tuna that is still red in the middle?

Yes, provided you are using "sushi-grade" or high-quality tuna that has been handled correctly. Flash-freezing, which is a standard for the premium tuna we provide, is a key step in ensuring the fish is safe for raw or rare consumption.

Can I use frozen tuna for this recipe?

Absolutely. In fact, most high-end tuna used for searing is frozen at sea to preserve its quality. Just ensure you thaw it properly in the refrigerator and pat it completely dry before you begin the searing process.

Why did my sesame seeds fall off in the pan?

This usually happens for two reasons: the fish wasn't dry enough before the binder was applied, or you didn't press the seeds firmly enough into the flesh. Make sure to use a binder like soy sauce or a light brush of oil and press the seeds down with your palm.

How do I know if my pan is hot enough?

The oil should be "shimmering" and have a slight sheen. If you place a corner of the fish into the pan and it doesn't sizzle immediately and loudly, the pan isn't hot enough. Wait another minute before adding the rest of the fish.

What is the difference between Ahi and Yellowfin?

"Ahi" is actually the Hawaiian word for both Yellowfin tuna and Bigeye tuna. In a culinary context, they are very similar—both have a firm texture and mild flavor that makes them ideal for searing with a sesame crust.

Can I bake tuna steak instead of searing it?

While you can bake tuna, you will not achieve the same crispy sesame crust or the rare center that makes this dish famous. Baking tends to cook the fish more evenly throughout, which can lead to a drier texture compared to a quick pan sear.

How should I store leftover seared tuna?

Store it in an airtight container in the fridge for up to 48 hours. It is best enjoyed cold the next day in a salad or over a poke-style bowl. Reheating is not recommended as it ruins the delicate texture of the rare center.

Where can I buy sushi-grade tuna for this recipe?

You can find premium, restaurant-quality tuna right here in our Seafood Collection. We offer convenient Home Delivery to ensure you get the freshest products delivered directly to your door.
