What Kind of Tuna Should I Use for Ruth’s Chris Ahi Tuna?

For this dish, quality makes all the difference. I always go for sushi-grade or sashimi-grade ahi tuna (also known as yellowfin tuna). You want a fresh, deep red fillet that’s safe to eat raw in the center, because the magic of this recipe lies in that beautiful contrast between the seared edge and the rare interior. Your local fishmonger or a reputable seafood counter should have what you need — just let them know you’re making seared ahi tuna and they’ll point you in the right direction.

Options for Substitutions

Even though this recipe is best with high-quality tuna, there are some smart swaps you can use if needed:

• Tuna Alternatives: If you can’t find ahi, try bluefin or albacore. Just make sure it’s sushi-grade.
• Sesame Seeds: No black sesame? You can use all white sesame seeds or add crushed black pepper for contrast.
• Soy Glaze: If you’re out of soy sauce glaze, try a quick mix of soy sauce, honey, and rice vinegar.
• Wasabi: Not a fan of heat? Leave out the wasabi or substitute with a little ginger paste for a milder kick.
• Greens on the Side: Any microgreens, arugula, or shredded cabbage will give that fresh contrast on the plate.

This recipe is flexible without losing its essence, so feel free to adapt it to your pantry or taste.

Ingredients for This Ruth’s Chris Ahi Tuna

Each ingredient in this dish serves a clear purpose — whether it’s adding texture, enhancing flavor, or building visual appeal. Here’s what you’ll need and why it matters:

• Sushi-Grade Ahi Tuna Steaks – The star of the show. Fresh, deep red tuna that can be safely eaten rare in the center.
• White Sesame Seeds – These give the seared crust a nutty flavor and golden finish.
• Black Sesame Seeds – Added for both crunch and striking contrast against the tuna.
• Soy Sauce – Adds a salty, umami base to both the glaze and the dipping component.
• Rice Vinegar – Balances the saltiness with acidity and brightness.
• Honey or Brown Sugar – Brings sweetness to the glaze and helps it caramelize slightly.
• Wasabi Paste – Optional but traditional — adds a spicy kick that cuts through the richness.
• Olive Oil or Avocado Oil – Used for searing; choose one with a high smoke point.
• Mixed Greens or Microgreens – For garnish and freshness; they balance the bold tuna flavor beautifully.

Every ingredient is here for a reason, and when they come together, they create a dish that’s layered, elegant, and unforgettable.

Step 1: Prepare the Tuna

Start by patting the tuna steaks dry with paper towels. This will help the sesame seeds stick better and ensure a perfect sear. Once dry, lightly coat the tuna with olive oil or avocado oil on all sides.

---

Step 2: Coat the Tuna with Sesame Seeds

Spread the white and black sesame seeds on a plate or shallow dish. Press each side of the tuna steaks into the seeds, ensuring an even coating. The sesame seeds should stick nicely to the oil-coated tuna. Don’t be shy — the more sesame seeds, the better the texture!

---

Step 3: Sear the Tuna

Heat a pan over medium-high heat and add a small drizzle of oil. Once the oil is hot, carefully place the tuna steaks into the pan. Sear each side for about 1-2 minutes, or until a golden-brown crust forms. The tuna should still be rare in the center, so don’t overcook it! Transfer the steaks to a cutting board and let them rest for a minute or so.

---

Step 4: Prepare the Soy Glaze

While the tuna rests, make the glaze by combining soy sauce, rice vinegar, and honey (or brown sugar) in a small saucepan. Bring it to a simmer over low heat and let it cook for about 2-3 minutes, or until it thickens slightly. Stir occasionally to prevent burning.

---

Step 5: Slice the Tuna

Once the tuna has rested, slice it into thick, bite-sized pieces. Each slice should reveal the beautiful contrast between the sesame-crusted edges and the rare, pink center.

---

Step 6: Plate the Dish

Arrange the tuna slices neatly on a plate. Drizzle the soy glaze over the tuna, and finish with a garnish of fresh greens or microgreens for color and freshness.

---

Each step is straightforward but creates a dish that’s rich in flavor and texture. Now you’ve got a restaurant-quality dish ready to impress.

How Long to Cook the Ruth’s Chris Ahi Tuna

The beauty of this recipe lies in its quick cooking time. Searing the tuna takes no longer than 1-2 minutes on each side. The goal is to create a crispy sesame crust while keeping the center rare and tender. Be sure not to overcook the tuna — it’s meant to remain cool and pink in the center. The total cook time is around 4-5 minutes, making it perfect for a quick yet sophisticated meal.

Tips for Perfect Ruth’s Chris Ahi Tuna

• Use Fresh Tuna: Always opt for sushi-grade tuna — it ensures the quality and safety of the raw fish in the center.
• High Heat for Searing: The pan should be hot, but not smoking. This allows for a perfect crust without overcooking the inside.
• Don’t Overcrowd the Pan: If you’re making multiple steaks, sear them in batches to avoid steaming the tuna.
• Rest the Tuna: Let the tuna rest for a minute or two after searing. This helps retain the juices inside and makes slicing easier.
• Adjust Glaze Consistency: If you prefer a thicker glaze, cook it a little longer. For a thinner glaze, reduce it less.

By following these tips, you’ll ensure that your Ruth’s Chris Ahi Tuna turns out perfectly every time.

Watch Out for These Mistakes While Cooking

• Overcooking the Tuna: The key to this dish is keeping the tuna rare in the center. If you cook it too long, you’ll lose that tender, melt-in-your-mouth texture.
• Not Using Enough Sesame Seeds: The sesame seeds are crucial for texture and flavor. Don’t skimp on them — press the tuna firmly into the seeds to ensure an even crust.
• Not Heating the Pan Enough: If the pan isn’t hot enough, the sesame seeds won’t sear properly, and you’ll miss that perfect crispy finish.
• Skipping the Resting Step: After searing, always let the tuna rest for a minute or two. This prevents the juices from spilling out when you slice it, ensuring a juicy bite.

Storage Instructions

Ruth’s Chris Ahi Tuna is best enjoyed fresh, as the tuna loses its tender texture when stored. However, if you need to store leftovers, follow these tips:

• Refrigeration: Place the leftover tuna in an airtight container and store it in the refrigerator for up to 1 day. Keep in mind that the tuna’s quality will degrade with time.
• Reheat Carefully: If you must reheat, do so gently in a pan over low heat for 1-2 minutes to avoid overcooking. It’s recommended to enjoy it cold if possible, as the tuna is traditionally served rare.

While fresh is always ideal, the leftovers can still make a tasty salad or sandwich filling the next day.

Frequently Asked Questions

1. Can I use frozen tuna for this recipe?

Yes, you can use frozen tuna, but make sure it’s thawed properly and is still sushi-grade. Freezing can affect the texture slightly, but it should still work if you follow the recipe carefully.

2. How can I tell if the tuna is sushi-grade?

Sushi-grade tuna is typically bright red with a firm texture and a fresh, oceanic smell. It should be safe to eat raw or rare in the center. Ask your fishmonger if you’re unsure!

3. Can I prepare the tuna in advance?

It’s best to prepare the tuna just before serving, but you can prep the sesame coating and soy glaze ahead of time. Store them separately and assemble right before searing.

4. Can I use a different kind of fish?

Ahi tuna is the best for this recipe, but you could substitute it with other firm fish like swordfish or even salmon, though they may require slightly different cooking times.

5. What if I don’t like wasabi?

You can skip the wasabi entirely or substitute it with a mild ginger paste or even a small amount of horseradish if you still want a little heat without the sharpness of wasabi.

6. How do I make the glaze thicker?

To thicken the glaze, let it simmer for a few more minutes until it reduces to your desired consistency. Be sure to stir regularly to avoid burning.

7. Is it necessary to let the tuna rest before slicing?

Yes, letting the tuna rest allows the juices to redistribute, making the fish more tender and juicy when you slice it.

8. Can I make this recipe without sesame seeds?

You can still make the tuna without sesame seeds, but it will miss that signature nutty crunch. You could use crushed black pepper or panko breadcrumbs as an alternative for some texture.
