Step 1

Place cod in colander and let sit to drain and get closer to room temperature, while you prepare rest of ingredients.

Step 2

In a small pan, combine all Lemon Butter Mixture ingredients and stir to fully combine. Set aside.

Step 3

Use paper towels to pat-dry all excess moisture from the fish fillets. This step is important, so be sure to pat off as much moisture as you can (extra moisture from fish will dilute flavors and steam the fish rather than brown it.)

Step 4

Evenly sprinkle both sides of fillets with pinches of kosher salt and freshly ground black pepper. Set aside. In a large pan, heat the olive oil over high heat. Once oil is sizzling hot, add fish fillets to pan (you may want to do 2 at a time to avoid crowding) and cover with lid ajar, allowing steam to escape. Cook until browned on one side, about 3-4 minutes. Do not move fish around.

Step 5

Use a thin but wide metal spatula to gently flip fish fillets over to the other side for another 3-4 minutes just until nicely browned and center is just-cooked. The key to tender fish is to avoid overcooking.If your fillets are less than 1-inch thick, shorten cook time.

Step 6

While your last fish fillets are cooking, heat up small pan of prepared lemon-garlic mixture over medium-high, stirring just until bubbly. Immediately turn heat off and keep warm.

Step 7

Once fish is done, plate fillets and spoon lemon butter mixture over the fish, including any leftover juices from your frying pan. Garnish with lemon slices and enjoy.
