Ingredients

Scale
  • 2 tuna steaks (6 oz each)
  • 1 tablespoon blackened seasoning
  • 1 tablespoon olive oil
  • Optional: Avocado-mango salsa for serving

Instructions

  1. Pat the tuna steaks dry with paper towels.
  2. Rub both sides of the tuna steaks with blackened seasoning.
  3. Heat olive oil in a skillet over medium-high heat, or preheat your grill or air fryer.
  4. Sear the tuna steaks for 2-3 minutes per side for medium-rare, or longer for your desired doneness. Use a meat thermometer for accuracy: 115°F for rare, 125°F for medium-rare, 135°F for medium.
  5. Let the tuna rest for a few minutes before serving.
  6. Serve with avocado-mango salsa if desired.

Notes

  • For meal prep, you can make a marinade ahead of time. Combine 1/4 cup olive oil, 2 tablespoons lemon juice, 1 tablespoon Worcestershire sauce, 1 teaspoon garlic powder, 1 teaspoon onion powder, and 1 teaspoon paprika. Marinate tuna for 30 minutes before seasoning and cooking.
  • This recipe is a great option for a healthy tuna dinner.
