How to Cook Tuna Steaks in the Oven

Fish, not only healthy but also tasty, is an option for those who cannot eat red meat. Tuna, a deep-sea fish often bought in the can, does well cut up into steaks and prepared in a number of ways, such as cooked in the oven. If looking for a simple and quick idea to try for dinner one night, then consider tuna steaks. Serve this dish to your family and watch them clean their plates.

Things You'll Need

  • Aluminum foil

  • 1 onion

  • 1 garlic clove

  • 1 tbsp. olive oil

  • Skillet

  • Tuna steaks

  • 4 tsp. butter

  • 1 tbsp. black pepper

  • Baking pan

  • 2 lemons

Step 1

Preheat the oven to 400 degrees F. The oven rack should be about 6 inches from the top burner. Next, tear off four pieces of aluminum foil that are double the size of 1-inch thick tuna steaks.

Step 2

Cut the onion and garlic clove into tiny pieces. Add the olive oil to a skillet and heat on medium high.

Step 3

Put the chopped onion and garlic into the skillet and cook for 10 minutes or until softened. Stir them often so they do not stick to the bottom and burn.

Step 4

Place one steak on each piece of foil. Rub 1 tsp. of butter onto both sides of each piece of fish.

Step 5

Sprinkle black pepper over the surface of the tuna. Evenly divide the sauteed onion and garlic onto the top of each steak.

Step 6

Fold the aluminum foil over the fish, making a loose envelope, and place the steaks on the baking pan.

Step 7

Bake the tuna steaks in the oven for 10 minutes. Next, take them out of the oven and place the pouches on plates, garnishing each with the slices of lemon. The flesh of fully cooked tuna is brownish-pink in color and flakes easily away from a fork.
