4 tilapia or other sustainable flaky white fish fillets (about 1 3/4 pounds total), divided
Salt and pepper
1 cup flour, for dredging
4 tablespoons extra virgin olive oil (EVOO), divided
4 tablespoons butter, divided
2 lemons, 1 sliced, 1 juiced (about 3 tablespoons)
1 large shallot, finely chopped
2 large cloves garlic, finely chopped
1/2 cup dry white wine or dry vermouth
2 tablespoons capers, drained
A handful of flat leaf parsley, chopped (about 2 tablespoons)
Pre-heat the oven to the lowest setting. Add a platter and four dinner plates; let warm while you make the tilapia.
Pat the fish dry; season with salt and pepper. Place the flour on a large plate. Dredge the fish lightly in the flour, shaking off the excess.
In a large skillet, heat 2 tablespoons EVOO, two turns of the pan, over medium-high. When the EVOO begins to smoke, melt in 1 tablespoon butter. Add two fillets and cook until opaque in the center, 2-4 minutes per side. Transfer the fish to the warm platter in the oven. Wipe the skillet clean, then repeat with the remaining 2 tablespoons EVOO, 1 tablespoon butter and two fillets.
Wipe the skillet clean, then add 1 tablespoon butter. When the butter melts, add the lemon slices and cook, turning once, until lightly browned, 2-3 minutes. Place the lemon slices on top of the fish.
Add the shallot and garlic to the skillet and stir until softened, about 1 minute. Add the wine, capers, parsley and lemon juice. Swirl in the remaining 1 tablespoon butter and simmer until the sauce thickens slightly, about 1 minute. Divide the fish among the warm plates. Season the lemon sauce and spoon over the fish.
