Ingredients

For the Fish:

4 white fish fillets (about 5 to 6 ounces each)
Salt and freshly ground black pepper, to taste
½ teaspoon garlic powder
¼ teaspoon paprika (optional, for color)
2 tablespoons all-purpose flour (for a light coating)
2 tablespoons olive oil

For the Lemon Butter Sauce:

4 tablespoons unsalted butter
3 garlic cloves, minced
Juice of 1 large lemon (about 2 to 3 tablespoons)
Zest of 1 lemon
2 tablespoons fresh parsley, chopped
1 tablespoon capers (optional, adds a savory touch)

Choosing the Right Fish

Any mild, flaky white fish works well for this recipe. Here are some great options:

Cod: Flaky and mild, very popular and budget-friendly
Tilapia: Mild flavor and widely available
Haddock: A bit firmer than cod, but still flaky
Snapper: Slightly sweeter taste with a firmer texture
Halibut: Meaty and rich, but often pricier
Salmon: Not white fish, but works well with lemon butter too

Fresh fish is ideal, but thawed frozen fillets work just as well. Make sure to pat them dry thoroughly before seasoning and cooking.

Step-by-Step Instructions

Step 1: Prepare the Fish

Pat each fillet dry with a paper towel. This step helps the seasoning stick and gives a better sear.

Season both sides of each fillet with salt, pepper, garlic powder, and paprika if using. Lightly dust with flour on both sides. This thin coating helps create a golden crust and helps the butter sauce stick to the fish.

Step 2: Sear the Fish

Heat the olive oil in a large nonstick skillet over medium-high heat. Once the oil is shimmering but not smoking, gently place the fillets in the pan.

Cook for 3 to 4 minutes on the first side, depending on the thickness of your fish. Flip carefully using a spatula and cook another 2 to 3 minutes on the second side, or until the fish is golden and flakes easily with a fork.

Transfer the cooked fillets to a plate and cover loosely with foil to keep warm.

Step 3: Make the Lemon Butter Sauce

Reduce the heat to medium. In the same skillet, melt the butter. Add the minced garlic and sauté for about 30 seconds, just until fragrant.

Add the lemon juice and zest, stirring to combine. Let it simmer gently for 1 to 2 minutes to let the flavors blend.

Add chopped parsley and capers if using, then stir and taste. Adjust seasoning with more lemon or a pinch of salt if needed.

Step 4: Combine and Serve

Return the fish to the skillet for just a moment to coat with the sauce, or spoon the sauce over the fillets while they rest on the plate.

Garnish with more parsley and lemon slices if desired. Serve immediately with your favorite sides.

Best Sides to Serve with Lemon Butter Fish Fillet

Expert Tips for Success

Dry the fish

Moisture on the surface will steam the fish instead of searing it. Use paper towels to dry it thoroughly before seasoning.

Don’t overcook

Fish cooks quickly, and overcooking leads to dryness. Aim for about 140°F internal temperature if you’re using a meat thermometer. When it flakes easily and looks opaque, it’s ready.

Use fresh lemon

Fresh lemon juice gives the sauce a clean, bright flavor that bottled juice just can’t match.

Add wine (optional)

A splash of white wine in the sauce after the garlic can add a lovely depth. Let it simmer for 30 seconds before adding the lemon juice.

Variations and Add-Ons

Spicy version: Add a pinch of red pepper flakes to the butter sauce for a subtle kick.
Mediterranean twist: Add cherry tomatoes, olives, and fresh basil.
Creamy lemon butter: Stir in 2 tablespoons of heavy cream for a richer sauce.
Panko-crusted: For a crunchier texture, coat the fish in egg and seasoned panko instead of flour and bake until golden.

Make-Ahead and Storage

This dish is best served fresh, but leftovers can be stored and enjoyed too.

Storage: Store leftovers in an airtight container in the fridge for up to 2 days.
Reheating: Warm gently in a skillet with a bit of butter or cover with foil and reheat in the oven at 300°F until heated through. Microwaving can make the fish rubbery, so it’s best avoided.
Freezing: Not recommended for this recipe, as the texture of the fish and sauce can change.

Frequently Asked Questions

Can I bake the fish instead?
Yes. Bake seasoned fillets at 375°F for 12 to 15 minutes or until cooked through, then spoon lemon butter sauce over just before serving.

What kind of pan should I use?
A nonstick or stainless-steel skillet works best for delicate fish. Cast iron is also fine if well-oiled and preheated.

Can I make this dairy-free?
Yes. Substitute butter with a plant-based butter alternative or a mix of olive oil and dairy-free margarine.

Is this recipe gluten-free?
You can make it gluten-free by skipping the flour or using a gluten-free flour blend.
