Freshly made herbed butter hits the spot in this excellent grilled fish recipe. It's a tasty way to flavour steamed or grilled vegetables, too.

Ingredients

Uncooked yellowfin tuna

1 pound(s), one steak cut 1 to 1-1/2 inches thick

Olive oil

1 tsp(s)

Fresh lime juice

1 tsp(s)

Cooking spray

1 spray(s)

Salted butter

2 tbsp(s), softened

Chives

1 tbsp(s), fresh, finely chopped

Fresh parsley

1 tbsp(s), fresh, finely chopped

Fresh tarragon

1 tbsp(s), finely chopped

Lime zest

1 tsp(s), fresh, minced

Table salt

¼ tsp(s), or more to taste

Black pepper

pinch, or more to taste

Fresh spinach

1 pound(s), baby-variety, steamed

Instructions

  1. Coat both sides of fish with oil and lime juice; set aside.
  2. Off heat, coat grill with cooking spray; preheat grill to high.
  3. Meanwhile, in a small metal bowl, combine softened butter, chives, parsley, tarragon, lime zest, salt and pepper; set aside.
  4. Cook tuna on one side for 3 minutes; carefully flip and cook on other side for 3 more minutes for rare, or longer until desired degree of doneness. Place bowl containing butter mixture on grill just until it melts—you don’t want to cook it.
  5. Thinly slice tuna and serve over spinach; drizzle melted herbed butter over top.
  6. Yields about 3 ounces of tuna and 1/4 of spinach per serving.

Notes

You can cook the tuna on a grill pan in the broiler, if you prefer. Tuna is prepared like steak in this recipe—cooked in one large piece on a very hot grill. If you like your tuna more well done, add about 1 minute to the total cooking time. But tuna cooks fast so make sure not to overcook it. The herbed butter topping is great on both the tuna and the spinach. Use a lemon if you don’t have a lime on hand.
