What Is Tuna Steak?

Tuna steak is a thick cut of tuna fish that is usually sliced from larger species like yellowfin or ahi tuna. Unlike canned tuna, fresh tuna steaks have a rich meaty texture that resembles beef steak in some ways.

Fresh tuna is often served medium-rare because overcooking can make it dry. A quick sear on high heat helps preserve the tender texture and natural flavor.

Popular types of tuna used for steaks include:

• Ahi tuna
• Yellowfin tuna
• Bluefin tuna
• Albacore tuna

Ahi tuna is especially popular because of its buttery texture and mild flavor.

Choosing the Best Tuna Steak

Fresh tuna makes a huge difference in this recipe. Here are some tips for selecting the best tuna steaks:

Color

Look for bright red or pink tuna. Avoid tuna that looks dull or brown.

Smell

Fresh tuna should smell clean and ocean-like, not fishy.

Thickness

Choose steaks about 1 to 1.5 inches thick for the best searing results.

Texture

The flesh should feel firm and moist.

How to Prepare Tuna Steak

Before cooking, remove the tuna steaks from the refrigerator about 15 minutes early. This helps them cook evenly.

Pat the tuna dry with paper towels. Removing extra moisture helps create a better crust during searing.

Step-by-Step Instructions

Step 1: Make the Marinade

In a bowl, combine:

• Soy sauce
• Sesame oil
• Olive oil
• Honey
• Ginger
• Garlic powder
• Salt
• Pepper

Whisk everything together until smooth.

Place the tuna steaks into the marinade and coat all sides. Let them marinate for about 10–15 minutes.

Do not marinate too long because the soy sauce can overpower the natural flavor of the tuna.

Step 2: Prepare the Sesame Crust

Remove each tuna steak from the marinade and gently press both sides into the sesame mixture.

Make sure the sesame seeds coat the tuna evenly.

Step 3: Cook the Noodles

Bring a pot of water to a boil.

Cook the noodles according to package instructions. Drain and toss with soy sauce, sesame oil, carrots, and green onions.

Set aside.

Step 4: Cook the Green Beans

Heat butter in a skillet over medium heat.

Add garlic and cook for 30 seconds until fragrant.

Add green beans and sauté for about 5 minutes until tender-crisp.

Season with salt and pepper.

Step 5: Make the Creamy Sauce

In a small bowl combine:

• Mayonnaise
• Soy sauce
• Sriracha
• Honey
• Lemon juice

Mix until creamy and smooth.

This sauce adds richness and balances the savory tuna.

Step 6: Sear the Tuna Steaks

Heat a cast-iron skillet over high heat.

Add a little oil.

Place the tuna steaks in the hot pan carefully.

Cook for:

• 1–2 minutes per side for rare
• 2–3 minutes per side for medium-rare
• 4 minutes per side for medium

Avoid overcooking.

The outside should develop a crispy crust while the inside remains tender and pink.

How to Know When Tuna Is Done

Tuna cooks very quickly.

Perfect tuna should:

• Be lightly pink in the center
• Feel firm outside
• Remain juicy inside

Overcooked tuna becomes dry and loses flavor.

If using a thermometer:

• Rare: 115°F
• Medium-rare: 125°F
• Medium: 130°F

Plating the Dinner

Arrange the noodles on one side of the plate.

Add green beans beside them.

Place the tuna steak in the center and slice slightly for presentation.

Serve with creamy sauce and grilled lemon halves.

Garnish with green onions or sesame seeds.
