Quick, easy, and healthy, our grilled tuna recipe can be prepared in just under 20 minutes. Drizzle olive oil and lime over the tuna before grilling it for a zesty flavor. If you don't have a lime on-hand, a lemon makes a nice substitution. The freshly made herb butter is the secret ingredient in this grilled fish recipe that also tastes great drizzled over the spinach. It's a tasty way to flavor steamed or grilled vegetables, too.


Cooking spray

4 spray(s)

Uncooked yellowfin tuna

1 pound(s), 1 steak (1 to 1 1⁄2 inches thick)

Olive oil

1 tsp

Fresh lime juice

1 tsp

Salted butter

2 Tbsp, softened


1 Tbsp, finely chopped

Fresh parsley

1 Tbsp, finely chopped

Fresh tarragon

1 Tbsp, finely chopped

Lime zest

1 tsp

Table salt

¼ tsp

Black pepper



1 pound(s), rinsed but not dried


  1. Off heat, coat grill rack or grill pan with nonstick spray. Preheat gas grill or grill pan to medium-high, or prepare medium-high fire in charcoal grill.
  2. Drizzle both sides of fish with oil and lime juice. In small metal bowl, combine butter, chives, parsley, tarragon, lime zest, salt, and black pepper.
  3. In large saucepan, cook spinach, covered, over medium-high heat until leaves are wilted, about 2 minutes. Remove from heat.
  4. Grill fish, turning once, until charred in spots and cooked to desired doneness, about 3 minutes per side for rare. Place bowl with herb butter directly on grill and let sit just until butter melts.
  5. Thinly slice fish. Divide spinach among plates and arrange fish on top. Drizzle melted herb butter over fish and spinach.
  6. Serving size: about 3 oz tuna and 1⁄4 of spinach


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 herb butter topping is great on both the tuna and the spinach. Use a lemon if you don’t have a lime on hand.
