When you want a quick weeknight dinner that feels like a meal from a high-end seafood restaurant, pan-seared white fish fillets in a glossy lemon garlic butter sauce are unbeatable. Featuring lightly seasoned fish fillets seared to a delicate golden brown, spooned over with warm garlic-infused butter, and topped with fresh lemon slices and parsley, this recipe delivers maximum flavor with minimal effort.
The beauty of this classic preparation lies in its simplicity. A mild white fish—such as cod, tilapia, flounder, halibut, or haddock—serves as the perfect canvas for rich, melted butter, bright fresh citrus, and fragrant minced garlic. Searing the fillets in hot olive oil first gives them a golden crust before basting them in butter, keeping the interior moist and flaky.
Serve these tender fillets immediately over a bed of fluffy jasmine rice, angel hair pasta, or roasted asparagus for a light, restaurant-quality meal!

Ingredient Notes
A great seafood dish relies on fresh, quality ingredients:
- White Fish Fillets: Cod, tilapia, halibut, flounder, sole, or sea bass fillets work exceptionally well. Choose fillets of uniform thickness so they cook evenly.
- Butter & Olive Oil: Cooking with a mixture of extra virgin olive oil and unsalted butter raises the smoke point while retaining that rich, silky butter flavor.
- Fresh Garlic: Finely minced fresh garlic adds pungent savory depth to the pan sauce.
- Fresh Lemon Juice & Slices: Citrus cuts through the richness of the butter, providing brightness and balancing the savory seasonings.
- Seasoning Blend: A subtle mix of paprika, garlic powder, sea salt, freshly cracked black pepper, and fresh parsley for garnish.
Always pat the fish fillets completely dry with paper towels before seasoning. Removing excess moisture is essential for getting a golden sear rather than steaming the fish in the pan.

Step-by-Step Instructions
- Dry and Season the Fillets: Pat 4 white fish fillets (about 6 oz each, total 1.5 lbs) thoroughly dry on both sides with paper towels. Season both sides evenly with 1 teaspoon kosher salt, 1/2 teaspoon freshly cracked black pepper, 1/2 teaspoon garlic powder, and 1/2 teaspoon paprika.
- Heat the Pan: Heat 1 tablespoon of extra virgin olive oil and 1 tablespoon of unsalted butter in a large skillet (cast-iron or stainless steel works best) over medium-high heat until hot and shimmering.
- Sear the Fish: Carefully lay the seasoned fish fillets into the hot pan, taking care not to overcrowd them. Fry for 3 to 4 minutes without moving them, allowing a light golden crust to form on the bottom.
- Flip carefully: Gently flip each fillet using a wide fish spatula. Reduce the heat slightly to medium.
- Make the Garlic Butter Sauce: Add the remaining 3 tablespoons of unsalted butter, 3 finely minced garlic cloves, and 2 tablespoons of freshly squeezed lemon juice to the skillet right next to the fillets.
- Baste and Finish Cooking: As the butter melts and foams, tilt the pan slightly and use a spoon to continuously baste the warm garlic butter over the tops of the fish fillets. Cook for another 3 to 4 minutes, until the fish is completely opaque throughout and flakes easily with a fork (internal temperature reaches 145°F / 63°C).
- Garnish and Serve: Transfer the tender fish fillets to a warmed plate or platter. Spoon the fragrant lemon garlic pan sauce liberally over the top. Top with thin fresh lemon slices and a sprinkle of chopped fresh parsley. Serve immediately.Tip: Basting the fish continuously with hot butter cooks the top gently, infusing the flavor deep into the delicate flakes.

Storage & Reheating
Store leftover pan-seared fish fillets in an airtight container in the refrigerator for up to 2 days.
To reheat without drying out the delicate fish, place the fillets in a covered skillet over low heat with a splash of water or a small knob of butter for 3–5 minutes until warm. Alternatively, heat in an oven or toaster oven preheated to 325°F (160°C) for 8 minutes.
Budget Note
Preparing white fish fillets at home is an affordable way to eat more seafood. A batch of 4 fillets costs approximately $3.00 to $5.00 per portion depending on the type of white fish used (e.g., tilapia or cod vs. halibut), compared to $22+ per plate at a seafood restaurant.
Recipe Variations
- Caper & Wine Piccata Style: Add 1 tablespoon of drained capers and 2 tablespoons of dry white wine to the pan sauce along with the lemon juice.
- Spicy Cajun White Fish: Swap out the paprika and garlic powder for a bold Cajun or Blackened seasoning rub before searing.
- Creamy Lemon Dill Sauce: Stir 2 tablespoons of heavy cream and 1 tablespoon of chopped fresh dill into the butter sauce right before removing from heat.
Frequently Asked Questions
What is the best white fish to use for pan searing? Cod, flounder, tilapia, and halibut are top choices. Flounder and sole are thinner and cook faster (2–3 mins per side), while thicker cod or halibut fillets take 4–5 mins per side.
Why did my fish break apart when flipping? Fish becomes delicate as it cooks. Ensure the pan is properly heated and oiled before adding the fish, don’t flip too early before a crust forms, and use a wide, flexible fish spatula to slide under the fillet gently.
Can I use frozen fish fillets? Yes, but they must be completely thawed first! Thaw overnight in the refrigerator, and make sure to thoroughly press out excess water using paper towels before cooking.
