Pan Seared Fish Fillet with Lemon Butter is a fast stovetop dinner built around a simple idea: season the fish well, give it time to brown, then finish it with butter, lemon, and capers. The result is crisp around the edges, tender in the center, and bright enough to serve with almost any simple side.
This method works especially well with firm fish fillets such as catfish, but you can use another fillet you enjoy. The most important part is starting with a dry surface and a hot pan so the fish sears instead of steaming.
Why This Pan Seared Fish Works
- Quick cooking: Fish fillets cook in minutes, making this useful for weeknight dinners.
- Simple pan sauce: Butter, lemon, and capers add flavor without requiring a separate sauce pot.
- Flexible fish choice: Catfish works well, but other firm fillets can be used too.
- Easy to pair: Serve it with salad, roasted vegetables, rice, or potatoes.
Tips for a Better Sear
Pat the fish dry before seasoning. Moisture on the surface makes browning more difficult. Heat the pan before adding the fish, then leave the first side alone long enough to develop color before flipping.
Butter adds flavor, but it can brown quickly at higher heat. Using a small amount of oil in the pan helps the fish sear while the butter adds richness. Once the fish is flipped, lowering the heat slightly gives the second side time to cook without scorching the butter.
Ingredient Notes
Fish fillets: Choose fillets of similar thickness so they finish cooking at about the same time.
Lemon: Fresh lemon adds acidity that balances the butter and seasoning.
Capers: A small amount adds a salty, briny bite that works especially well with mild fish.
Ingredients
- Fish fillets, such as catfish
- 1 lemon
- 1 tablespoon capers
- 2 tablespoons butter
- Seafood seasoning, to taste
- Olive oil, just enough to lightly coat the pan
How to Make Pan Seared Fish Fillet
- Pat the fish fillets dry and season them generously with seafood seasoning.
- Heat a skillet over medium-high heat. Add enough olive oil to lightly coat the pan, then add the butter.
- Place the fish in the hot skillet and cook for about 4 to 5 minutes on the first side, or until nicely browned.
- Add sliced lemon, a squeeze of lemon juice, and the capers to the pan.
- Flip the fish, reduce the heat to medium, and cook for another 4 to 5 minutes, or until the fish is cooked through and flakes easily.
- Spoon the lemon-butter pan juices over the fish and serve warm.
Storage and Reheating
Refrigerate leftover fish in a covered container for up to 2 days. Reheat gently in a skillet over low heat or in a low oven. High heat can dry the fish quickly, so warm it only until heated through.
