Heavy skillet

Small mixing bowl
Whisk

Ingredients

2 sushi-grade tuna steaks 6 ounces each, 170 grams
1 tablespoon avocado oil 15 ml
Sea salt and freshly ground black pepper to taste
½ cup mayonnaise 120 ml
1 teaspoon wasabi paste 5 grams
1 tablespoon lemon juice 15 ml
1 teaspoon soy sauce or coconut aminos 5 ml
1 garlic clove, minced about 1 gram
1 teaspoon ginger, freshly grated 2 grams

Instructions

Step 1: Begin by patting the tuna steaks dry with paper towels. Season both sides with sea salt and freshly ground black pepper.
Step 2: Heat the avocado oil in a heavy skillet over high heat until just smoking. Carefully place the tuna in the skillet and sear for about 1 minute on each side for rare, or longer if preferred. Once seared to your liking, transfer the tuna steaks to a cutting board and let them rest.
Step 3: To make the wasabi aioli, combine the mayonnaise, wasabi paste, lemon juice, soy sauce or coconut aminos, minced garlic, and grated ginger in a bowl. Whisk the ingredients together until smooth and fully integrated.
Step 4: Slice the tuna steaks against the grain into 1/4-inch thick slices. Arrange the slices on plates.
Step 5: Drizzle the wasabi aioli over the seared tuna slices or serve on the side for dipping. Garnish with additional wasabi or ginger if desired.

Notes

For the best flavor and texture, use sushi-grade tuna and consume the dish immediately after preparation. Adjust the amount of wasabi in the aioli to suit your taste and spice tolerance. If you're avoiding soy, opt for coconut aminos, which provide a similar umami flavor without the carbs. This dish can be served as a main course or sliced into smaller pieces for a keto-friendly appetizer.
