Ingredients

For the Tuna Steaks

  • 4 (6 ounce) tuna steaks, 1-inch thick
  • 2 tablespoons olive oil
  • 2 tablespoons blackening seasoning

For the Avocado Crema

  • 1 large ripe avocado
  • 1/4 cup sour cream or Greek yogurt
  • 1 tablespoon lime juice
  • 1 clove garlic, minced
  • Salt to taste
  • Fresh cilantro, chopped (for garnish, optional)

Instructions

  1. Prepare the Tuna Steaks: Pat the tuna steaks dry thoroughly using paper towels to ensure proper searing. Rub each side of the tuna with olive oil, then generously coat both sides with blackening seasoning for maximum flavor.
  2. Heat the Skillet: Place a cast-iron skillet over high heat and allow it to become smoking hot, approximately 5 minutes. This high temperature is essential to achieve a perfect blackened crust.
  3. Cook the Tuna: Carefully place the seasoned tuna steaks onto the hot skillet. Cook each side for 1 to 2 minutes if you prefer your tuna rare. Adjust cooking time accordingly if you desire a more cooked steak, but be careful not to overcook to maintain tenderness.
  4. Make the Avocado Crema: While the tuna is cooking, prepare the creamy avocado sauce. Combine the ripe avocado, sour cream or Greek yogurt, lime juice, minced garlic, and salt in a food processor or blender. Blend until the mixture is smooth and creamy with no lumps.
  5. Rest the Tuna: Once cooked, remove the tuna steaks from the skillet and let them rest for a few minutes. This helps redistribute the juices and enhances flavor and tenderness.
  6. Serve: Plate the tuna steaks and generously spoon the avocado crema over or alongside them. Garnish with fresh chopped cilantro if you wish, and serve immediately for the best taste and texture.

Notes

  • The secret ingredient in this recipe is the creamy avocado crema, which adds freshness and a subtle tang that complements the spicy blackened seasoning.
  • For best results, use a cast-iron skillet to get a perfect sear and blackened crust on the tuna.
  • You can substitute Greek yogurt for sour cream to lighten the avocado crema and add protein.
  • Adjust blackening seasoning quantity based on spice tolerance.
  • Ensure tuna steaks are fresh and thick-cut for optimal texture and flavor.
