- Fresh parsley: Finely chopped for a fresh, herbaceous note that brightens the butter.
- Fresh lemon juice: Adds necessary acidity and lightness to counterbalance the richness.
- Lemon zest: For an intense lemon aroma that makes every bite pop.

How to Make Seared Tuna Steaks with Lemon, Caper, and Parsley Butter Recipe
Step 1: Prepare the Lemon, Caper, and Parsley Butter
Begin by combining the softened butter, chopped capers, fresh parsley, lemon juice, and lemon zest in a small bowl. Sprinkle in salt and freshly ground black pepper to your taste, then mix everything thoroughly. This vibrant butter will melt over the hot tuna steaks and infuse each bite with bright, tangy goodness.
Step 2: Season the Tuna Steaks
Pat your fresh tuna steaks dry and generously season both sides with salt and black pepper. This simple seasoning forms the foundation and ensures every mouthful bursts with perfectly balanced flavors.
Step 3: Heat the Skillet and Sear the Tuna
Place a skillet over medium-high heat and pour in the olive oil. Wait until it shimmers, which indicates it’s hot enough to give the tuna those beautiful sear marks and a slightly crispy exterior. Carefully lay the tuna steaks in the pan and let them cook for about 2 minutes on each side if you like your tuna rare. For more doneness, just add extra cooking time—remember, tuna can easily dry out, so keep an eye on it!
Step 4: Finish with the Lemon, Caper, and Parsley Butter
Once your tuna steaks have reached the desired doneness, reduce the heat to low. Place a generous dollop of the lemon, caper, and parsley butter on top of each steak. Watch it melt slowly, soaking into the warm fish, enriching every bite with creamy, zesty flavor. Don’t rush this step—let the butter gently embrace the tuna.
Step 5: Plate and Garnish
Transfer the seared tuna steaks carefully onto your serving plates. Spoon any remaining melted butter from the pan over the steaks to add a touch of gloss and extra flavor. Serve immediately with fresh lemon wedges for an extra splash of citrus if desired.

Garnishes
The simplest garnishes often make the dish shine the brightest. Fresh lemon wedges are perfect for squeezing over before eating, boosting the bright flavors. A sprinkle of additional chopped parsley adds a pop of green and a fresh herbal note that complements the butter beautifully. If you want a little crunch, toasted pine nuts or thinly sliced radishes provide excellent textural contrast.
Side Dishes
Seared Tuna Steaks with Lemon, Caper, and Parsley Butter Recipe pairs wonderfully with light, fresh sides. Serve alongside a crisp green salad with a lemon vinaigrette or roasted asparagus for a healthy touch. Herb quinoa or a simple wild rice pilaf also works well, soaking up any buttery, flavorful juices from the tuna.
Creative Ways to Present
If you want to impress your guests or simply enjoy your meal in style, try serving your tuna steaks atop a bed of creamy mashed potatoes or alongside a colorful ratatouille. For a more casual yet stunning presentation, slice the tuna thinly to create a beautiful tuna tataki platter, drizzling the melted lemon-caper butter and garnishing with fresh herbs and edible flowers.
Make Ahead and Storage
Storing Leftovers
If you happen to have any leftovers of this Seared Tuna Steaks with Lemon, Caper, and Parsley Butter Recipe, wrap them tightly in plastic wrap or store in an airtight container. Refrigerate promptly and consume within 1 to 2 days for the best flavor and texture.
Freezing
For best quality, it’s not recommended to freeze cooked tuna steaks as the texture may suffer upon thawing. However, you can freeze the lemon, caper, and parsley butter separately in small portions, which can be thawed and used fresh with freshly cooked tuna later on.
Reheating
Reheating seared tuna is best done gently to avoid overcooking. Use a low oven setting (around 275°F/135°C) and warm for just a few minutes, or briefly in a skillet over low heat. Avoid microwaving as it can make the tuna dry and tough.
FAQs
Can I use frozen tuna steaks for this recipe?
Yes, you can use frozen tuna steaks as long as they’re fully thawed and patted dry before cooking. Freshness is key for the best flavor, so try to use high-quality tuna whether fresh or frozen.
How do I know when the tuna is cooked perfectly?
Seared tuna is often enjoyed rare or medium-rare, where the outside has a nice crust but the inside is still pink. Cooking approximately 2 minutes per side usually achieves this, but times vary based on steak thickness. Use your judgment or a cooking thermometer aiming for an internal temperature around 115°F to 120°F for rare.
Can I substitute other herbs for parsley?
Absolutely! While parsley offers a bright freshness, herbs like cilantro, basil, or tarragon can provide different but equally wonderful flavor profiles in the butter. Just make sure to use fresh herbs for the best results.
Is there a way to make this recipe dairy-free?
Yes, you can substitute the butter with a high-quality olive oil or a dairy-free butter alternative. The texture will be slightly different, but the lemon, capers, and herbs will still shine through wonderfully.
What can I serve instead of lemon wedges?
If lemon wedges aren’t your favorite, a drizzle of extra virgin olive oil infused with garlic or chili flakes can add a lovely finishing touch. Alternatively, a small dollop of citrusy aioli works beautifully as a dipping sauce alongside the tuna steaks.
