Ingredients for Ruth’s Chris Ahi Tuna

8 oz sashimi-grade Ahi tuna (center-cut loin)
2 tbsp black and white sesame seeds (or cracked black pepper for variation)
1 tbsp olive oil
Sea salt, to taste
Microgreens or scallions, for garnish

For the Sauce:

2 tbsp soy sauce
1 tbsp rice vinegar
1 tsp sesame oil
1 tsp Dijon mustard
1 tsp honey
1 clove garlic, finely minced
1 tsp fresh ginger, grated

Step 1: Prepare the Tuna

Start with a high-quality, sashimi-grade Ahi tuna steak. Pat it dry using paper towels to remove any excess moisture. Lightly season it with sea salt on all sides.

Step 2: Coat with Sesame or Pepper

Spread the sesame seeds or crushed black pepper evenly on a plate. Gently press the tuna into the coating so all sides are evenly covered. This crust gives the dish its signature texture and visual flair.

Step 3: Sear the Tuna

Heat olive oil in a non-stick skillet over high heat. When the oil shimmers, add the tuna steak. Sear for about 30 seconds to 1 minute per side—just until the outer layer is browned but the inside remains rare. Remove from heat and let it rest for a minute before slicing.

Step 4: Make the Signature Sauce

While the tuna rests, whisk together the soy sauce, rice vinegar, sesame oil, Dijon mustard, honey, garlic, and grated ginger in a bowl. This creates a tangy, savory, and slightly sweet glaze that enhances the umami flavor of the tuna.

Step 5: Slice and Plate

Using a sharp knife, cut the seared tuna into thick slices. Arrange artfully on a platter or plate. Drizzle the soy-ginger sauce over or around the tuna slices.

Step 6: Garnish and Serve

Top each slice with microgreens or finely chopped scallions. Serve immediately while the tuna is still slightly warm, paired with pickled ginger, wasabi, or a light salad for a complete fine-dining experience.

Frequently Asked Questions

1. Can I use frozen tuna for this dish?

Yes, as long as it’s sashimi-grade and thoroughly thawed in the refrigerator before cooking. Make sure it’s from a reputable source.

2. What does “sashimi-grade” mean?

It refers to fish that’s safe to eat raw, having been flash-frozen to eliminate parasites. Always look for this label when buying tuna for searing rare.

3. How rare should the center be?

The ideal Ruth’s Chris Ahi Tuna is seared on the outside and rare (deep pink) in the center. It should be cool and tender inside.

4. Can I make this ahead of time?

It’s best made fresh, but you can prepare the sauce and crust in advance. Sear the tuna just before serving.

5. Is this dish gluten-free?

It can be if you use gluten-free soy sauce (like tamari). Double-check all sauce ingredients for hidden gluten.

6. What sides go well with this?

Light and fresh options like a cucumber salad, steamed edamame, or jasmine rice complement the flavors well.

7. Can I grill the tuna instead of searing in a pan?

Absolutely. A very hot grill can achieve the same quick sear, but be careful not to overcook.

8. Is the sauce spicy?

No, it’s more tangy and savory. For heat, feel free to add a few drops of sriracha or freshly chopped chili to the sauce.
