Pat the fish dry. Use paper towels to remove surface moisture from the tilapia. Dry fillets sear better and develop a light crust.

Season both sides. Sprinkle with salt and pepper. Add a pinch of red pepper flakes if you like a little heat.

Optional light dredge. Dust each fillet with flour and shake off the excess. This step is optional but helps with browning and keeps the fish tender.

Prep your flavor base. Zest one lemon, then cut both lemons in half. Mince the garlic and chop the parsley. Keep everything within reach.

Heat the pan. Set a large skillet over medium to medium-high heat. Add olive oil and 1 tablespoon butter. When the butter foams and smells nutty, you’re ready.

Cook the tilapia. Lay fillets in the pan without crowding. Cook 2–3 minutes per side, depending on thickness, until the fish is opaque and flakes easily. Transfer to a warm plate and tent loosely with foil.

Build the sauce. Lower heat to medium-low. Add the remaining 1 tablespoon butter to the skillet, then stir in the garlic. Cook 30–45 seconds until fragrant, not browned.

Deglaze and brighten. Squeeze in the juice of 1 to 1.5 lemons (about 3–4 tablespoons) and add the lemon zest. Scrape up any browned bits from the pan. Stir in capers if using.

Finish and taste. Simmer the sauce for 30 seconds to meld. Taste and adjust salt, pepper, and lemon. You want a balanced tangy-buttery flavor.

Serve. Spoon the lemon garlic sauce over the tilapia. Shower with chopped parsley. Add extra lemon wedges on the side.
