Level:
4 (6 ounce) yellowfin tuna steaks
½ cup vegetable oil
⅓ cup soy sauce
¼ cup fresh lemon juice
2 teaspoons Dijon mustard
1 teaspoon grated lemon peel
1 clove garlic, crushed
4 wedges lemon, for garnish
Ingredients
Preparation
Prick tuna steaks all over with a fork and place in a shallow glass baking dish.
Whisk together oil, soy sauce, lemon juice, Dijon mustard, lemon peel, and garlic in a bowl; pour over tuna steaks. Cover the dish with plastic wrap and refrigerate for 1 to 3 hours.
Preheat the grill to medium heat and lightly oil the grate.
Remove tuna from marinade; shake excess marinade from steaks and transfer to a plate.
Pour marinade into a small saucepan; bring to a boil. Reduce heat to medium-low and simmer marinade for 10 minutes.
Cook tuna on the preheated grill, basting with boiled marinade, until cooked through, 5 to 6 minutes per side. Serve with lemon wedges.
