2 tablespoons olive oil
-
3 cloves garlic, minced

Step-by-Step Instructions
Preparing the Fish
I start by patting the fish fillets completely dry with paper towels. This helps them get a nice golden color when cooked. Then I season both sides with salt, pepper, and paprika. I make sure the seasoning is evenly distributed across all the fillets.
Cooking to Perfection
I heat olive oil in a large skillet over medium-high heat. Once the oil is shimmering, I carefully place the fish fillets in the pan without overcrowding them. I cook for 3-4 minutes on the first side until golden brown, then flip and cook for another 2-3 minutes until the fish flakes easily with a fork. I transfer the cooked fish to a plate and keep it warm.
Making the Lemon Butter Sauce
In the same skillet, I reduce the heat to medium and add the butter. Once it melts, I add the minced garlic and sauté for about 30 seconds until fragrant. Then I pour in the fresh lemon juice and let the sauce simmer for 1 minute. I stir in the chopped parsley and taste to adjust seasoning. I spoon this gorgeous sauce over the fish fillets and serve immediately with lemon slices.
Perfect Pairings and Serving Ideas
I love serving this fish with steamed broccoli or sautéed green beans. Roasted baby potatoes or garlic rice make excellent sides that soak up the delicious lemon butter sauce. For a lighter option, I pair it with a crisp Caesar salad or roasted vegetables. A glass of white wine and some crusty bread to mop up the sauce complete the meal beautifully.
Pro Tips for Success
I’ve learned that using room temperature fish cooks more evenly than cold fish straight from the fridge. I let my fillets sit out for 10-15 minutes before cooking. The key to avoiding dry fish is not overcooking it—I remove it from heat as soon as it flakes easily. If my fillets are thick, I cover the pan for the last minute to ensure they cook through. Using freshly squeezed lemon juice instead of bottled makes a huge difference in flavor.
Ways to Make It Your Own
I sometimes add capers to the sauce for a briny kick or swap the parsley for fresh dill or basil. For extra richness, I finish the sauce with a tablespoon of heavy cream. When I want more heat, I add red pepper flakes to the garlic. I’ve also made this with salmon instead of white fish, and it’s equally delicious. Adding cherry tomatoes to the pan during the last minute creates a beautiful presentation.
Choosing the Best Fish
I prefer cod or halibut for their mild flavor and firm texture, but tilapia, mahi-mahi, or sea bass work wonderfully too. I look for fillets that are firm, moist, and smell fresh like the ocean, not fishy. Thicker fillets hold up better during cooking and are less likely to fall apart. If I’m using frozen fish, I thaw it overnight in the refrigerator and pat it extra dry before cooking.

Frequently Asked Questions
How do I know when the fish is done?
The fish is ready when it turns opaque and flakes easily when tested with a fork. The internal temperature should reach 145°F. I avoid overcooking because fish continues cooking slightly after removing it from heat.
Can I use frozen fish fillets?
Yes, but make sure to thaw them completely in the refrigerator overnight. I always pat frozen fish extra dry to remove excess moisture, which helps achieve a better sear.
What if I don’t have fresh lemon?
While fresh lemon is best, I’ve used bottled lemon juice in a pinch. Use about 2 tablespoons and add a bit of lemon zest if you have it to boost the flavor.
Can I make this ahead of time?
Fish is best cooked fresh, but I can prepare the sauce ahead and reheat it when ready. The entire dish cooks so quickly that I don’t usually need to prep ahead.
Why is my fish sticking to the pan?
Make sure your pan is hot enough before adding the fish and that the fillets are completely dry. Don’t move the fish too soon—let it develop a golden crust for 2-3 minutes before flipping.
