  • Before cooking tuna steaks, check for scales. If any are present, rinse with cool water. Pat dry with paper towels.
  • Measure the thickness of the fish with a ruler, so you know how long to cook tuna steak.
  • Fresh tuna steaks love a good marinade recipe, which flavors this fairly mild fish and helps keep it moist during cooking. A short marinating time is all it needs, from 15 minutes to 4 hours in the refrigerator. Tuna pairs especially well with Asian-inspired flavors.
  • Instead of marinating, you can brush the fish with olive oil or melted butter and season as desired. For example, try brushing tuna with olive oil and lemon juice, then sprinkle it with snipped fresh herbs (such as rosemary or tarragon), salt, and ground black pepper. Or try one of these delicious spice blends.

How to Cook Tuna Steaks 3 Ways

Tuna steaks need a watchful eye during cooking to remain tender and moist. Don't be turned off if your tuna looks medium-rare, whether you're baking tuna steak, skillet-cooking tuna steak, or grilling it. Because tuna steaks get dry and chewy when overcooked, the center should still be pink when it's done cooking. Some people like their tuna even more rare in the center, so adjust these suggestions on how long to cook tuna steaks accordingly.

How to Grill Tuna Steaks

Take a break from beef burgers, hot dogs, and shrimp skewers, and become a pro at cooking tuna on a grill by following these simple steps.

  1. Grease the unheated grill ($174, Walmart) rack or spray it with nonstick cooking spray. If not marinated, brush the tuna steaks with melted butter or olive oil, and season as desired.
  2. For direct grilling on a gas or charcoal grill, place the tuna steaks on the greased grill rack directly over medium heat. Grill, covered, for 4 to 6 minutes per ½-inch thickness or until fish begins to flake when tested with a fork but is still pink in the center, turning once halfway through cooking.
  3. For indirect grilling, preheat the grill. Reduce heat to medium and place tuna on the grill rack over a drip pan. Cover the grill. Grill 7 to 9 minutes per ½-inch thickness or until fish begins to flake when tested with a fork but is still pink in the center, turning once halfway through cooking.

If desired, try this Test Kitchen trick for cooking tuna steak on a grill that's even more flavorful: Brush tuna with additional melted butter or olive oil after turning. (So you're fully prepared for cooking tuna steaks for your next barbecue, stock up on these 10 must-have grilling tools ASAP.

How to Cook Tuna Steaks in a Skillet

Searing tuna steaks in a hot skillet caramelizes the surfaces of the fish and locks in the moisture. For best results when mastering how to cook tuna steak on a stove, start with ¾-inch-thick steaks.

  1. Choose a heavy skillet ($20, Bed Bath & Beyond) that best fits the number of tuna steaks you are cooking. Add 1 Tbsp. oil and 1 Tbsp. butter to the skillet. Heat the skillet over medium-high heat until hot.
  2. Add the tuna steaks. The steaks should sizzle when added. Cook, uncovered, 4 to 6 minutes per ½-inch thickness (6 to 9 minutes for the ¾-inch-thick steaks we suggest) or until fish begins to flake when tested with a fork but is still pink in the center, turning once during cooking. Adjust the heat as needed if the skillet gets too hot.

How to Buy and Store Fresh Tuna

Any method of cooking tuna will produce the best results if you start with a good piece of tuna. Here's what to look for.

  • Fresh tuna comes in a long loin that a fishmonger (a person or retailer that sells fish) cuts into tuna steaks. Tuna season is usually late spring into early fall, but it's available frozen year-round. If you're wondering how to cook frozen tuna steak, you can follow the instructions above after thawing the tuna steaks in the fridge for 24 to 48 hours.
  • Raw tuna varies from light pink to a reddish-brown color, depending on the variety. It can have a dark portion on the steak, which is edible but stronger in flavor. Sometimes this part is trimmed out before you buy it.
  • Tuna steaks are sold skinned. Look for tuna with moist flesh and a fresh and pleasant, not fishy, smell.
  • When purchasing, figure on one 4- to 5-ounce tuna steak per person. For optimum freshness, cook tuna the day you buy it.
