Instructions: How to Make the Fantastic Lemon Butter Fillet

Fish fillets cooking in butter

1. Prep the Fillets

Pat the fillets dry with a paper towel and season them on both sides with salt and pepper. This helps them sear nicely and prevents excess moisture from watering down your sauce.

2. Sear to Perfection

Heat the olive oil in a large skillet over medium-high heat. Once shimmering, place the fillets in the pan and cook for 3–4 minutes per side (depending on thickness), until they are golden and cooked through. Remove and set aside.

3. Create the Lemon Butter Sauce

Reduce the heat to medium-low. In the same pan, add butter and let it melt slowly. Add the minced garlic and sauté for 30 seconds until fragrant. Stir in the lemon juice and zest, letting the sauce simmer for a minute.

4. Bring it All Together

Return the fillets to the pan, spooning the lemon butter sauce over them. Let everything warm together for another minute or two. Sprinkle with freshly chopped parsley and garnish with lemon slices.

Pro Tips for the Best Lemon Butter Fillet

Use fresh lemon juice: Bottled lemon juice lacks the zing of fresh.

  • Don’t overcook the fish: It should flake easily with a fork, not fall apart.
  • Butter matters: Use high-quality unsalted butter for the richest flavor.
