Ingredients You’ll Need

The quality of tuna steaks is paramount in this recipe—look for fresh, untouched cuts for the best results. A combination of parsley, thyme, and rosemary in the garlic herb butter not only adds flavor but also creates a wonderful aroma as they melt together. Feel free to experiment with herbs based on what you have on hand, but do keep the lemon juice for brightness.

  • 2 tuna steaks (6-8 ounces each), about 1 inch thick
  • 2 tablespoons olive oil
  • Salt, to taste
  • Freshly ground black pepper, to taste
  • 2 tablespoons unsalted butter, softened
  • 2 cloves garlic, minced
  • 2 tablespoons chopped fresh herbs (parsley, thyme, rosemary, or a combination)
  • 1 tablespoon lemon juice

How to Make Seared Tuna Steaks with Garlic Herb Butter

  1. Pat the tuna steaks dry with paper towels, ensuring they’re fully dried for a perfect sear. Season them generously with salt and freshly ground black pepper on both sides.
  2. In a small bowl, mix together the softened butter, minced garlic, chopped herbs, and lemon juice until well combined for your garlic herb butter. Set this aside to allow the flavors to meld.
  3. Heat the olive oil in a heavy-bottomed skillet over high heat until shimmering—this is crucial for that beautiful sear.
  4. Carefully place the seasoned tuna steaks in the hot skillet. Sear for approximately 2-3 minutes on each side, looking for a nice golden-brown crust. Adjust the cooking time to achieve your desired doneness; for medium-rare, the center should still feel soft.
  5. Once done, remove the tuna steaks from the skillet and transfer them to a plate. Top each steak with about a tablespoon of the garlic herb butter, allowing it to melt over the warm fish.
  6. Let the butter melt slightly before serving to create a glossy finish. Enjoy your gourmet meal!

Tips for Best Results

  • Make sure your skillet is hot enough before adding the tuna to avoid sticking and ensure a good sear.
  • Use a fish spatula to gently flip the steaks without breaking them apart.
  • Keep an eye on the tuna, as it cooks quickly; overcooking can lead to a dry texture.
  • Double the recipe for the garlic herb butter to have extra on hand for bread or vegetables.

Variations and Substitutions

  • If you don’t have fresh herbs, a pinch of dried herbs can work in a pinch, though the flavor will be less vibrant.
  • Consider adding a splash of soy sauce for an umami kick if you’re looking for an additional flavor layer.
  • For a spicy twist, a dash of chili flakes can be mixed into the garlic herb butter.
