Tuna steak is a wonderfully easy-to-make dinner and lunch choice that is often overlooked by home cooks. Packed with protein and very filling, tuna steaks make a delicious main. When served with baked potatoes and grilled vegetables, these spicy steaks make a wholesome meal. Incredibly versatile, tuna steaks can be served instead of the classic grilled chicken breast at your next BBQ and make a great alternative to red meat for when you are entertaining all sorts of dietary needs and preferences. Ready in just 25 minutes, after a 30-minute marinade, the steaks must be quickly cooked on a very hot grill. So preheat your grill and give it time to achieve the right temperature.

Our easy marinade has the perfect amount of spice, but it can be adjusted to your preference by adding more or less cayenne pepper. The bright flavors of shallots and cilantro complement the tangy citrus juice (lemon or lime) and make a flavorful marinade that can also be used on beef, chicken, and other types of fish. Tuna steaks are rich in lean protein and Omega 3 fatty acids, besides bringing to your table great levels of niacin and vitamins B12 and D. A 6-once steak of raw bluefin tuna has a whopping 40 grams of protein, just 8 grams of fat, and an outstanding 16 μg of vitamin B12—the recommended daily intake is just 2.4 μg.

Thinly sliced and served inside of tacos with tangy coleslaw, or placed on a bed of sushi rice, the steaks can be part of any style of meal you like. Accompany the steaks with garlic spaghetti or pesto gnocchi, serve on top of a green salad for a low-carb option, or use with avocado or lettuce "buns" for a keto alternative. When buying tuna, the steaks are usually cut to order at the fish counter from a bigger loin, so always look for shiny meat and moisture. If the steaks are already cut, look for a vibrant color—depending on the type of tuna the color varies from red to pink—and meat that looks somehow wet. Avoid dull or brown streaks and fish that smells too fishy, as fresh tuna should smell like the sea and not like a fish tank.
