🐟 Ingredients

½ pound ahi tuna steaks. ¼ pound each if using two steaks.
2 tablespoons soy sauce.
3 tablespoons olive oil. Divided.
1 teaspoon minced garlic.
1 teaspoon lemon juice.
6 large eggs.
2 tablespoons butter. Divided.
½ teaspoon salt. Adjust to taste.
¼ teaspoon pepper. Adjust to taste.
1½ teaspoon non-pareil capers.
2 teaspoons fresh dill. Chopped. If you find the flavor of dill to be too strong, you can substitute thyme or basil.

Make Ahead Tip

Prepare the simple marinade the night before. Add the tuna steaks to the marinade, cover with plastic wrap, and place in your fridge overnight. They will be ready to go the next morning!

📝 Instructions

Step 1. In a small bowl, combine soy sauce, 2 tablespoons olive oil, minced garlic and lemon juice to make a marinade.

Place tuna steaks in a small bowl and pour marinade over the top. Make sure steaks are fully coated with marinade, cover with plastic wrap, and refrigerate at least one hour or overnight.

Remove steaks to a cutting board and allow to rest for 3 minutes. Wipe out skillet with a paper towel.

Overhead view of eggs and salt and pepper in a blender — **Step 4.** Meanwhile, add eggs and salt and pepper to a blender and blend for about 1 minute. Alternatively, you can add the eggs and salt and pepper to a medium bowl and whisk vigorously for 1-2 minutes.

Seared ahi tuna slices on a cutting board — **Step 5.** Thinly slice tuna steaks and season with lemon juice if desired. It's okay that they are rare inside. They will cook a bit more inside the omelette. You do not want to overcook the tuna because that will make it dry and rubbery.

Overhead view of butter melting in a skillet — **Step 6.** Melt 1 tablespoon butter in skillet over medium heat.

Overhead view of uncooked beaten eggs in a skillet — **Step 7.** Add half of the egg mixture and cook until warmed and the edges are beginning to set, about 30 seconds.

At the same time, lift and tilt the pan to allow the liquid egg on top to flow underneath, then cook for 30 seconds longer.

Step 8. When the eggs are almost set but still moist on top, lay ½ of the tuna slices on one side of the omelette.

Step 9. Sprinkle ½ of the capers and dill over the top of the tuna slices.

Overhead view of cooked omelette in a skillet — **Step 10.** Using a wide spatula, fold the untopped half of the omelette over the filled half. Allow to cook about 30 seconds longer to allow the omelette to meld together. Slide the omelette onto a serving plate.

Repeat steps 7-10 for the second omelette. Serve warm.

💡 Tips for Success

A few tips to get you off and running to make the perfect omelette:

Use a non-stick skillet. A non-stick skillet will make it easier to lift the edges of the eggs as necessary cook and achieve a beautiful omelette.
Blend the eggs in a blender, along with salt and pepper, before adding them to the skillet. This will make for a fluffier omelette.
When the egg edges begin to set, gently lift the edge and push it toward the center of the pan. Then gently tilt the pan so that the uncooked liquid can flow underneath. Continue working your way around the perimeter as necessary until no liquid egg remains.
When adding the filling, only add it to one half of the omelette then use a heatproof spatula to cover that half with the unfilled half.
