Ingredients You’ll Need
Let’s take a closer look at each component in this dish and how it contributes to the final flavor and texture.
Ahi Tuna Steaks
Opt for fresh, sushi-grade steaks that are at least one inch thick. Quality matters here, especially if you prefer your tuna rare or medium-rare.
Olive Oil
Used to sear the tuna, creating a golden crust while keeping the inside tender and juicy.
Unsalted Butter
This is the foundation of the sauce. It adds richness and creates a smooth, velvety texture when combined with garlic.
Garlic
Freshly minced garlic infuses the butter with savory flavor and gives the dish its signature aroma.
Parsley
A handful of chopped parsley brightens the overall taste and adds a pop of color.
Lemon Juice
A squeeze of lemon balances the richness of the butter and enhances the natural flavor of the fish.
Salt and Pepper
Don’t skip seasoning. Salt and freshly cracked black pepper ensure that the tuna is flavorful with every bite.
How to Make Garlic Butter Ahi Tuna
This recipe follows a straightforward process. First, the tuna steaks are seared quickly in olive oil to lock in moisture and flavor. Then, you’ll build a quick sauce in the same pan using butter, garlic, herbs, and lemon. The fish is returned to the skillet to soak up the sauce before serving.
The process is easy but delivers impressive results. You’ll be surprised how such a simple preparation can produce a meal with so much depth.

Step-by-Step Instructions
Step 1: Dry and Season the Tuna
Blot the tuna steaks with paper towels until completely dry. This ensures a better sear. Season both sides of the steaks with salt and black pepper.
Step 2: Preheat the Skillet
Heat the olive oil in a large pan over medium-high heat. Wait until the oil shimmers before adding the tuna.
Step 3: Sear the Tuna
Place the steaks into the hot pan. Sear for 1 to 2 minutes per side if you want it rare, or 2 to 3 minutes for medium-rare. The outside should have a golden crust while the inside remains pink.
Step 4: Set the Tuna Aside
Remove the seared steaks from the pan and place them on a plate. Tent loosely with foil to keep them warm.
Step 5: Build the Garlic Butter Sauce
Lower the heat to medium-low. Add the butter to the same skillet. When melted, stir in the minced garlic. Cook for 30 seconds, stirring constantly to avoid burning.
Step 6: Add Lemon Juice and Herbs
Stir in the chopped parsley and lemon juice. Allow the sauce to simmer gently for another 15 to 20 seconds so the flavors meld.
Step 7: Return the Tuna to the Pan
Place the steaks back in the skillet. Spoon the sauce over them so each side gets fully coated in the garlic butter.
Step 8: Serve Immediately
Transfer the tuna steaks to serving plates. Pour the remaining sauce over the top and serve while hot with your preferred side dish.
Helpful Tips
- Use high-quality tuna for the best results, especially if you like your fish rare.
- Make sure the pan is fully preheated before adding the tuna to get a good sear.
- Garlic cooks quickly, so keep an eye on it to prevent burning.
- Let the tuna rest for a minute or two if slicing before serving.
- Add chili flakes to the butter if you like a little heat.
