Ingredients
This recipe makes 4 servings.
- For the Tuna Steaks:
- 4 (6-8 ounce) tuna steaks, about 1-inch thick, fresh or thawed
- 1 tablespoon olive oil
- 1 teaspoon sea salt
- ½ teaspoon black pepper, freshly ground
- For the Garlic Butter:
- ½ cup unsalted butter, softened
- 4 cloves garlic, minced
- 2 tablespoons fresh parsley, finely chopped, plus extra for garnish
- 1 tablespoon fresh lemon juice
- ½ teaspoon sea salt
- ¼ teaspoon black pepper, freshly ground
- Optional Garnish:
- Lemon wedges
Step-by-Step Instructions
-
Step 1: Prepare the Tuna Steaks
Gently pat the tuna steaks dry with paper towels. This helps them get a better sear. Brush both sides of each tuna steak with olive oil. Season generously with sea salt and freshly ground black pepper. Set them aside while you prepare the garlic butter.
Small tip: Drying the tuna is crucial for a beautiful crust. Don’t skip this step!
-
Step 2: Make the Garlic Butter
In a small bowl, combine the softened unsalted butter, minced garlic, chopped fresh parsley, fresh lemon juice, sea salt, and black pepper. Mix everything together until it’s well combined and creamy. This can be done with a fork or a small whisk.
Small tip: Make sure your butter is truly softened, not melted, for the best consistency. You can leave it on the counter for 30 minutes or gently microwave for 10-15 seconds.
-
Step 3: Preheat Your Grill
Preheat your grill to high heat (about 450-500°F or 230-260°C). Make sure the grill grates are clean. Once hot, lightly oil the grates to prevent sticking. This creates the perfect surface for grilling your tuna.
Small tip: A hot grill is key for a good sear and prevents the tuna from sticking. Use tongs to wipe the grates with an oil-soaked paper towel.
-
Step 4: Grill the Tuna Steaks
Carefully place the seasoned tuna steaks on the hot, oiled grill grates. Grill for 2-3 minutes per side for medium-rare, or 3-4 minutes per side for medium. The cooking time will depend on the thickness of your steaks and your desired doneness.
Small tip: Tuna is best served medium-rare, with a pink center. Overcooking will make it dry and tough.
-
Step 5: Baste and Finish Grilling
During the last minute of grilling, generously brush the garlic butter onto both sides of the tuna steaks. The butter will melt into the fish, infusing it with incredible flavor. Continue to grill briefly, just until the butter is melted and fragrant.
Small tip: Use a silicone brush for easy basting. Be careful not to let the butter drip directly onto the flames, as it can cause flare-ups.
-
Step 6: Rest and Serve
Once cooked to your liking, remove the tuna steaks from the grill. Place them on a platter and let them rest for 2-3 minutes. This allows the juices to redistribute, ensuring a tender and moist steak. Garnish with extra fresh parsley and lemon wedges, if desired, and serve immediately.
Small tip: Resting meat is just as important as cooking it. It locks in all those delicious juices.
Tips & Variations
- Gluten-Free Option: This recipe is naturally gluten-free! All the ingredients used are free from gluten, making it a perfect choice for those with dietary restrictions.
- Vegan or Vegetarian Option: For a delicious plant-based alternative, try grilling thick slices of portobello mushrooms instead of tuna. Marinate them in a mixture of olive oil, soy sauce (or tamari), garlic, and herbs before grilling. For the “butter,” use a high-quality vegan butter alternative.
- Add More Vegetables or Protein: Grill some asparagus spears, bell peppers, or zucchini alongside your tuna for a complete meal. You can also add some grilled shrimp or scallops for extra protein and variety.
- Spicy Version: For a kick of heat, add a pinch or two of red pepper flakes to your garlic butter mixture. You can also sprinkle a little cayenne pepper on the tuna steaks before grilling.
- Herb Variations: Feel free to experiment with other fresh herbs in your garlic butter. Dill, chives, or oregano would all be wonderful additions. A little lemon zest added to the butter also brightens the flavor beautifully.

Health Benefits
Grilled Tuna Steaks with Garlic Butter is not just delicious; it offers some wonderful health benefits too! Tuna is a powerhouse of nutrition, especially when it comes to lean protein. It’s essential for building and repairing tissues in your body, keeping you feeling full and satisfied.
One of the most celebrated aspects of tuna is its high content of Omega-3 fatty acids, particularly EPA and DHA. These healthy fats are incredibly beneficial for heart health, brain function, and reducing inflammation throughout the body. Regular consumption of Omega-3s can contribute to a healthier cardiovascular system.
Tuna is also a great source of several important vitamins and minerals. It provides B vitamins like B12, B6, and niacin, which are crucial for energy production and nerve function. You’ll also find minerals such as selenium, which acts as an antioxidant, and magnesium, important for muscle and nerve function.
Garlic, a key component of our flavorful butter, is another fantastic ingredient for your health. It’s known for its immune-boosting properties and contains compounds that may help reduce blood pressure and cholesterol levels. Plus, the olive oil used for brushing the tuna contributes monounsaturated fats, which are considered heart-healthy fats.
Serving Suggestions
- Serve your grilled tuna with a fresh, vibrant side salad tossed with a light vinaigrette. The crispness of the salad provides a lovely contrast to the rich tuna.
- Pair it with roasted or steamed vegetables like asparagus, green beans, or broccoli. A simple squeeze of lemon over the veggies complements the tuna beautifully.
- For a heartier meal, serve alongside a fluffy quinoa salad, wild rice, or even some creamy mashed potatoes. The tuna can be the star of a light dinner or a more substantial plate.
- Meal Prep Ideas: If you have leftover grilled tuna, flake it and use it in a tuna salad sandwich (light on the mayo!), a vibrant pasta salad, or as a topping for green salads throughout the week. It’s a great way to add healthy protein to your lunches.
Storage Tips: Leftover grilled tuna steaks should be stored in an airtight container in the refrigerator. They will keep well for 2-3 days. While you can freeze cooked tuna, it often changes the texture, making it drier, so it’s best enjoyed fresh. To reheat, gently warm the tuna in a pan over low heat or in a microwave on a low setting, being careful not to overcook it and dry it out. A little extra garlic butter can help revive it!
