- 100g salted butter: Creates the luscious base for the lemon, caper, and parsley sauce.
- 3 tablespoons baby capers: Add a salty, slightly tangy punch to brighten the butter sauce.
- 2½ tablespoons chopped fresh parsley: Brings a fresh, herbal lift that contrasts beautifully with the rich butter.

How to Make Seared Tuna Steaks with Lemon, Caper & Parsley Butter Recipe
Step 1: Prep and Season the Tuna
Begin by brushing each tuna steak generously with olive oil. This not only helps create that irresistible golden crust but also prevents sticking during cooking. Season both sides with sea salt and freshly ground pepper—simple but critical, as this layers foundational taste right from the start.
Step 2: Perfectly Sear the Tuna
Preheat a large griddle or non-stick frying pan over medium-high heat until hot but not smoking. Place the tuna steaks on the pan, hearing that satisfying sizzle. Cook each side for about 3 to 5 minutes. The goal is a beautifully caramelized exterior with a still-pink center, ensuring the tuna stays tender and juicy. Remember, the residual heat will continue to gently cook the fish once off the pan, so timing here is everything.
Step 3: Prepare the Lemon, Caper & Parsley Butter Sauce
While the tuna is resting, melt the salted butter gently in a small pot. Once melted, stir in the baby capers, fresh parsley, and lemon juice. Bring this mixture to a simmer to marry the flavors, allowing the capers’ salty tang and lemon’s brightness to infuse the creamy butter. This sauce is what turns the dish from simple to spectacular.
Step 4: Bring It All Together
Plate the seared tuna steaks, then generously spoon the warm lemon, caper, and parsley butter sauce over them. Garnish with caperberries and lemon wedges for a final pop of flavor and a stunning presentation. The contrast of textures and tastes here is truly irresistible.
How to Serve Seared Tuna Steaks with Lemon, Caper & Parsley Butter Recipe

Garnishes
Adding caperberries and fresh lemon wedges not only elevates the visual appeal of your plate but also offers bursts of salty and citrusy goodness for anyone wanting an extra kick. Fresh parsley sprigs can also enhance color and freshness.
Side Dishes
This dish pairs wonderfully with light, crisp sides such as a simple mixed green salad tossed with a lemon vinaigrette, or roasted asparagus. For a heartier meal, creamy mashed potatoes or a silky risotto absorb the flavorful butter sauce beautifully.
Creative Ways to Present
For a dinner party, arrange the tuna steaks atop a bed of sautéed spinach or alongside a delicate quinoa salad with cucumber and herbs. Drizzle any remaining lemon butter sauce artistically across the plate to impress your guests visually and taste-wise.
Make Ahead and Storage
Storing Leftovers
Store any leftover tuna steaks in an airtight container in the refrigerator and consume within 1 to 2 days. The lemon, caper & parsley butter sauce will keep beautifully covered to maintain flavor and moisture.
Freezing
Because fresh tuna tastes best when freshly cooked, freezing the cooked steaks is not recommended. However, you can freeze the lemon caper butter sauce separately in a freezer-safe container for up to a month.
Reheating
Reheat leftovers gently in a pan over low heat just until warmed through, to avoid overcooking the tender tuna. Pour over freshly warmed lemon caper butter sauce for best results.
FAQs
Can I use frozen tuna steaks for this recipe?
While fresh tuna is ideal for a tender, pink center, you can use thawed frozen tuna steaks if fresh isn’t available. Just be sure to pat them dry well before cooking to get a good sear.
How do I know when the tuna is cooked perfectly?
Look for a nicely browned crust on the outside with a translucent pink center. Cooking times will vary with thickness but aim for about 3-5 minutes per side for medium rare.
Can I substitute the capers with something else?
Capers are key for their distinctive salty tang, but if you don’t have them, finely chopped green olives can offer a similar briny punch, though the flavor will be slightly different.
Is this recipe suitable for a weeknight meal?
Absolutely—this Seared Tuna Steaks with Lemon, Caper & Parsley Butter Recipe comes together quickly and easily, making it perfect for both casual dinners and special occasions.
What wine pairs well with this dish?
A crisp white wine like Sauvignon Blanc or a light rosé beautifully complements the citrusy, buttery sauce and the mild flavor of the tuna.
