Step 1

Place a rack in the center of your oven and preheat to 425 degrees F.

Step 2

In a large, shallow plate (a pie dish works well), combine the flour, 1 teaspoon salt, and pepper. Pat the salmon fillets dry with paper towels and sprinkle the remaining ¼ teaspoon salt over the top.

Step 3

Melt the butter in a large (12-inch) oven safe cast iron skillet or similar sturdy-bottomed oven safe skillet over medium heat. Continue to heat, swirling the pan periodically, until it begins to brown.

Step 4

Reduce the heat to medium-low. Dredge both sides of the salmon fillets in the flour mixture. Shake off the excess then gently place them in the hot butter, top-side down. Cook without disturbing them for 3 minutes, until the top is golden brown. When the salmon turns opaque on the sides and starts to turn opaque on top, use a flexible spatula to flip the salmon.

Step 5

Add the lemon zest and lemon juice to the pan. Place the skillet immediately into the oven and let cook for 6 minutes (the salmon will appear a little undercooked in the center but will finish cooking as it rests). Remove from the oven and cover with foil. Let rest 4 to 5 minutes.

Step 6

To serve, place each piece of salmon on a plate and spoon the pan sauce liberally over the top. Sprinkle with fresh parsley and capers. Season with additional salt and pepper to taste. Enjoy immediately.
