Remove the tuna from the skillet and set aside. 4. In the same skillet, melt butter and add capers. Cook for a minute. 5. Add lemon juice to the skillet and stir to combine. 6. Pour the lemon-caper sauce over the tuna steak. 7. Garnish with fresh parsley and serve hot.

Tips for Tuna Steak with Lemon-Caper Sauce

A glossy sauce that clings to the fish is ready; avoid reducing the lemon juice until it tastes harsh or overly sharp.
A heavy skillet helps the tuna sear evenly, and a thin, flexible spatula makes it easier to turn without tearing.
For more even cooking, let the tuna sit out briefly while you prepare the other ingredients, rather than cooking it straight from the refrigerator.

Drink pairing

a crisp, dry Sauvignon Blanc
Its bright citrus character complements the lemon-caper sauce without overwhelming the tuna.

0% option: Sparkling water with a lemon wedge

Storage

Refrigerate leftover tuna and sauce within 2 hours in a covered container and use within 3–4 days. Reheat until steaming hot, though the tuna may become firmer.

Frequently asked questions

How can I tell whether the tuna is done?

For the recipe’s medium-rare finish, the outside should be seared while the center remains visibly pink and tender. Cook longer if you prefer it more done.
