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

For the best results, use sushi-grade or sashimi-grade ahi tuna (also called yellowfin tuna). This ensures that the fish is safe to eat rare or medium-rare, which is essential to getting that iconic deep pink center and buttery texture. Avoid overly frozen or lower-quality tuna steaks, as they can become chewy and lose their flavor.

Ingredients for the Ruth’s Chris Ahi Tuna

Sushi-grade Ahi Tuna steaks: The star of the dish. Choose center-cut for even cooking.
Sesame seeds (black and white): These add a nutty crunch and an attractive crust.
Soy sauce: For a rich, umami base to the glaze and dipping sauce.
Fresh ginger and garlic: Essential for the marinade, adding warmth and a hint of spice.
Rice vinegar: Balances the soy sauce with acidity.
Honey or brown sugar: A touch of sweetness enhances the glaze.
Sriracha or wasabi (optional): For heat, if you want to add a spicy kick.
Mixed greens or microgreens: Serve alongside for freshness and visual appeal.
Olive oil or sesame oil: Used for searing and adding richness.

How To Make the Ruth’s Chris Ahi Tuna

Step 1: Prepare the Marinade

In a small bowl, whisk together soy sauce, grated fresh ginger, minced garlic, rice vinegar, and a touch of honey or brown sugar. This mixture will serve as both a marinade and a drizzle for serving.

Step 2: Coat the Tuna

Pat your ahi tuna steaks dry with a paper towel. Press both sides into a shallow plate filled with a mix of black and white sesame seeds until well coated. This step creates the signature crunchy crust.

Step 3: Sear the Tuna

Heat sesame oil or olive oil in a heavy skillet over high heat until shimmering. Sear the tuna steaks for about 30-45 seconds per side. You want a golden sesame crust while keeping the interior rare and ruby red.

Step 4: Slice and Serve

Remove the tuna from the pan and let it rest for a minute. Using a sharp knife, slice the steaks into 1/2-inch pieces. Arrange them on a plate with fresh greens or microgreens.

Step 5: Drizzle with Sauce

Drizzle the reserved marinade over the sliced tuna or serve it on the side as a dipping sauce. Garnish with additional sesame seeds or a light drizzle of sriracha if you like it spicy.

Serving and Storing Ruth’s Chris Ahi Tuna

This ahi tuna is best served immediately after slicing. The warm seared edges paired with the cool, rare center offer the ideal contrast. Pair it with a light salad, jasmine rice, or even alongside a chilled glass of crisp white wine or sake.

If you have leftovers, store them in an airtight container in the fridge for up to 24 hours. For food safety, avoid reheating the tuna; instead, enjoy it chilled as part of a salad or poke bowl.

Frequently Asked Questions

Can I use frozen tuna for this recipe?

Yes, but it must be labeled sushi-grade and properly thawed. Pat dry thoroughly to prevent steaming in the pan.

How do I know when the tuna is perfectly seared?

You’re looking for a golden crust on the outside and a deep pink or red center. Each side needs just 30-45 seconds on high heat.

What if I don’t like it rare?

You can cook the tuna longer, but keep in mind it will become firmer and lose its delicate texture. Medium-rare is a good middle ground.

What sides go well with this dish?

Steamed rice, seaweed salad, cucumber ribbons, or a miso soup pair beautifully with seared ahi tuna.

Can I make the marinade ahead of time?

Absolutely. You can mix the marinade up to 3 days in advance and store it in the fridge until you’re ready to use.

Is this recipe keto-friendly?

Yes! Just be sure to use a sugar-free sweetener in place of honey or brown sugar.
