A quick and elegant recipe for perfectly seared ahi tuna steaks paired with a smooth, tangy wasabi cream sauce that balances richness with a gentle spicy kick.

Ingredients

Scale
  • 6 oz (170 g) ahi tuna steaks, fresh and sashimi-grade if possible
  • 1 tablespoon (15 ml) sesame oil
  • 1 tablespoon (15 ml) olive oil
  • Salt, to taste
  • Freshly ground black pepper, to taste
  • 1 teaspoon (5 g) wasabi paste
  • 1/4 cup (60 ml) sour cream
  • 2 tablespoons (30 ml) mayonnaise
  • 1 teaspoon (5 ml) lime juice, freshly squeezed
  • 1 teaspoon (5 ml) soy sauce, preferably low sodium
  • 1 tablespoon finely chopped green onions (optional)

Instructions

  1. Prepare the Wasabi Cream Sauce: In a small mixing bowl, combine 1/4 cup sour cream, 2 tablespoons mayonnaise, 1 teaspoon wasabi paste, 1 teaspoon lime juice, and 1 teaspoon soy sauce. Whisk until smooth and creamy. Taste and adjust wasabi or lime juice as desired. Cover and refrigerate while cooking the tuna. (5 minutes)
  2. Prep the Tuna Steaks: Pat the ahi tuna steaks dry with paper towels. Lightly season both sides with salt and freshly ground black pepper. (2 minutes)
  3. Heat the Pan: Place a skillet over medium-high heat and add 1 tablespoon sesame oil and 1 tablespoon olive oil. Heat until shimmering but not smoking, about 2 minutes. (2 minutes)
  4. Sear the Tuna: Place the tuna steaks in the hot pan. Sear without moving for about 1 minute 15 seconds. Flip and sear the other side for another 1 minute 15 seconds. The center should remain rare with a warm pink color. Adjust time for thickness. (3 minutes)
  5. Rest and Slice: Transfer tuna to a cutting board and let rest for 2 minutes. Slice against the grain into 1/4-inch thick pieces if desired. (3 minutes)
  6. Plate and Serve: Arrange sliced tuna on plates and drizzle or dollop with chilled wasabi cream sauce. Sprinkle with chopped green onions for garnish. (2 minutes)

Notes

Pat tuna dry before searing to avoid steaming. Use a combination of sesame and olive oil for flavor and heat control. Adjust wasabi paste carefully to avoid overpowering the tuna. Rest tuna before slicing for juicier bites. Keep wasabi cream sauce refrigerated until serving. For gluten-free, use tamari instead of soy sauce. Dairy-free sauce can be made by substituting sour cream and mayonnaise with coconut yogurt and vegan mayo.
