1-First Step: Prep the fish and spice mix Start by patting the fish fillets dry with paper towels. This helps the seasoning stick and gives the fish a better sear. In a small bowl, mix together the paprika, garlic powder, salt, and black pepper. Rub the spice mixture over all sides of the fish fillets. If you are using a thicker white fish, like halibut or grouper, make sure the seasoning covers the top and edges well. For a lighter version, you can slightly reduce the salt and still get plenty of flavor from the lemon butter sauce later.

2-Second Step: Warm the skillet and sear the fish Heat a skillet over medium heat for 1 minute. This quick preheat helps the fish begin cooking right away instead of sticking to a cold pan. Add the olive oil, then place the fillets in the skillet carefully. Cook the fish for about 2 minutes per side. The exact time depends on thickness, but most 4-ounce fillets will be close to done with this timing. You want a lightly golden exterior and fish that lifts easily from the pan. If your fillets are very thin, check them a little earlier so they do not overcook.

3-Third Step: Make the browned butter sauce Once the fish is cooked through, remove it from the pan and reduce the heat. Add the butter and let it cook for 1 to 2 minutes until it browns. Watch it closely because browned butter can move from nutty to burnt fast. Stir in the lemon juice, parsley, and a pinch of salt and pepper. Let the sauce cook for another 2 minutes so the flavors come together. If you like a little heat, add fresh garlic and red pepper flakes here. That is an easy way to give this zesty lemon butter fish fillet a sharper kick.

4-Fourth Step: Return the fish and finish gently Add the lemon slices to the pan, then return the fish to the skillet. Cook over medium-low heat for 3 more minutes. During this time, spoon the sauce over the fish every 30 seconds so each piece gets coated with that glossy lemon butter flavor. This final simmer helps the fish soak up the sauce without drying out. If you are using a delicate fish like flounder, keep the heat low and spoon gently so the fillets stay intact. For firmer fish like cod or halibut, the same method works beautifully and gives you a nice, sturdy finish.

5-Final Step: Serve right away Transfer the fish to plates and spoon extra sauce over the top. Garnish with fresh lemon slices and serve it while hot. This recipe makes about 4 servings, and it tastes especially good with roasted baby potatoes, grilled vegetables, grains, or a simple side salad.
