Ingredients
Marinade Ingredients
- ¼ cup gluten-free tamari or soy sauce
- 2 tablespoons unseasoned rice vinegar
- 2 tablespoons sesame oil
- 2 teaspoons maple syrup or honey
- 2 teaspoons grated fresh ginger
- ½ teaspoon sea salt
Main Ingredient
- 2 pounds fresh ahi tuna steaks (sushi-grade)
Instructions
- Prepare the Marinade: In a small mixing bowl, thoroughly whisk together the gluten-free tamari, rice vinegar, sesame oil, maple syrup or honey, grated fresh ginger, and sea salt until well combined.
- Separate Marinade for Serving: Remove about half of the marinade (approximately ¼ cup) and transfer it to a serving bowl to use later as a dipping sauce.
- Marinate the Tuna: Place the remaining marinade in a shallow dish or resealable plastic bag. Add the ahi tuna steaks to this dish or bag, turning them to coat evenly with the marinade on all sides.
- Marinating Time: Allow the tuna to marinate for at least 10 minutes at room temperature to absorb flavors, or for deeper flavor, refrigerate and marinate overnight in a resealable container.
- Cook the Tuna: Remove the tuna from the marinade and cook it using your preferred method—either grill the steaks over medium-high heat or sear them quickly on a hot stovetop skillet until desired doneness is reached. Keep the cooking brief to preserve the delicate texture of the ahi tuna.
- Slice and Serve: Thinly slice the cooked tuna steaks. Serve the slices alongside the reserved marinade dipping sauce and consider adding optional garnishes such as sesame seeds or sliced green onions for extra flavor and presentation.
Notes
- For optimal flavor, marinate the ahi tuna steaks overnight in the refrigerator, but a minimum of 10 minutes also works well.
- If grilling, preheat the grill to medium-high and oil the grates to prevent sticking.
- When searing on the stove, use a very hot pan and sear the tuna for about 1-2 minutes per side for rare to medium-rare doneness.
- Optional garnishes that complement this marinade include toasted sesame seeds, sliced green onions, or fresh cilantro.
- This marinade is naturally gluten-free when using tamari, and suitable for pescatarians and those avoiding dairy.
