Ingredient Quantities

  • 2 fresh tuna steaks (about 6 oz each)

  • 1 teaspoon fresh thyme leaves, chopped
  • Salt, to taste
  • Freshly ground black pepper, to taste

How to Make this

1. Wipe the tuna steaks with a paper towel to remove excess moisture, and then apply salt and freshly ground black pepper to both sides. Be generous; this fish can handle a lot of seasoning.

2. In a tiny bowl, mix together the Dijon mustard, the whole-grain mustard, and the chopped fresh thyme leaves to form a paste.

3. Spread the mustard-thyme blend equally over the opposing sides of the tuna steaks.

4. Olive oil should be heated in a large skillet, over a medium to high heat setting, until the oil shimmers.

5. Add the tuna steaks to the hot skillet with care and sear them for around 2 minutes on the first side.

6. Sear the other side of the tuna steaks for 1 to 2 minutes, depending on how done you want them. The steaks should have a crispy crust and remain pink in the center.

7. Set aside the tuna steaks for one to two minutes after removing them from the skillet, and place them on a cutting board.

8. Cut the tuna steaks into thick strips, slicing against the grain.

9. On a serving platter, arrange the slices and garnish them with fresh lemon wedges.

10. Immediate service is recommended, with the optional addition of lemon juice to taste, over the tuna. Seared Tuna Steaks with Mustard Thyme are ready for your enjoyment!

Seared Tuna Steaks With Mustard Thyme Recipe Substitutions and Variations

Substitute avocado oil or grapeseed oil for olive oil.
Dijon mustard: Substitute with spicy brown mustard or yellow mustard.
Mustard made with whole grains: Substitute with coarsely ground mustard or more Dijon mustard.
Fresh thyme leaves: Use 1/2 teaspoon dried thyme instead.
Wedges of lemon: Use wedges of lime instead, or feel free to use a dash of lemon juice.

Pro Tips

1. Pat Dry Thoroughly: Ensure the tuna steaks are completely dry before seasoning. This helps achieve a perfect sear and crispy crust when cooking.

2. Preheat the Skillet Well: Before adding olive oil, ensure the skillet is properly heated. The oil should shimmer but not smoke. A hot skillet ensures a quick sear, locking in moisture and flavor.

3. Use a Cast Iron Skillet: For an even and well-retained heat distribution, consider using a cast iron skillet. It enhances the sear and crust formation on the tuna steaks.

4. Monitor Tuna Doneness: If you prefer a rare center, sear the steaks for about 1-2 minutes per side. Adjust the searing time based on your doneness preference, remembering that tuna continues to cook slightly after removing from heat.

5. Rest Before Slicing: Allow the tuna steaks to rest for a minute or two after cooking. This helps the juices redistribute and prevents the tuna from drying out when sliced.
