Step-by-Step Instructions

Step 1: Prepare the Tuna

Pat the tuna steaks dry with paper towels. This helps them sear nicely in the pan.

Sprinkle both sides with salt, black pepper, and paprika if you are using it. Gently press the seasoning into the fish.

Let the tuna sit at room temperature for about 5 minutes. This helps it cook evenly.

Step 2: Heat the Pan

Place a large skillet on the stove over medium-high heat.

Add the olive oil. Let it heat until it looks slightly shiny but not smoking. The pan must be hot before adding the tuna. This helps create a nice golden crust.

---

Step 3: Sear the Tuna

Carefully place the tuna steaks in the hot pan.

Cook for about 2–3 minutes on the first side without moving them. This creates a beautiful crust.

Flip the tuna and cook for another 1–2 minutes for medium-rare. If you prefer it more cooked, add another minute per side.

Small Tip: Ahi tuna tastes best when it is slightly pink in the center. Overcooking can make it dry.

Once done, remove the tuna from the pan and place it on a plate. Cover loosely with foil.

Step 4: Make the Garlic Butter Sauce

Lower the heat to medium.

In the same pan, add the butter. Let it melt slowly.

Add the minced garlic. Cook for about 30–60 seconds until fragrant. Stir constantly so the garlic does not burn. Burned garlic tastes bitter.

Add lemon juice, lemon zest, and soy sauce if using. Stir well and let it cook for another 30 seconds.

Turn off the heat.

Step 5: Combine and Serve

Place the tuna steaks back into the pan. Spoon the garlic butter sauce over the top.

Let the tuna sit in the sauce for about 1 minute to absorb the flavors.

Sprinkle chopped fresh parsley on top.

Serve immediately with lemon wedges on the side.

Tips & Variations

This recipe is simple, but you can easily change it to fit your taste.

1. Make It Spicy

Add a pinch of red pepper flakes or a small amount of chili paste to the garlic butter sauce.

Fresh thyme or rosemary can be added to the butter for a deeper flavor.

3. Asian-Inspired Version

Add a teaspoon of sesame oil and sprinkle sesame seeds on top. Serve with steamed rice and stir-fried vegetables.

4. Dairy-Free Option

Replace butter with vegan butter or extra olive oil. The flavor will still be delicious.

Use gluten-free soy sauce or tamari. Everything else in the recipe is naturally gluten-free.

6. Low-Sodium Version

Reduce the salt and skip the soy sauce. Use extra lemon juice for flavor instead.

7. Well-Done Tuna

If you prefer fully cooked tuna, cook each side for about 3–4 minutes. Keep in mind the texture will be firmer.
