Jump to RecipeWhy You’ll Love This Recipe
There is something especially appealing about a dinner that tastes restaurant-worthy but asks very little from the cook. This fish recipe uses one skillet, a short ingredient list, and a quick sauce that comes together while the cooked fillets rest.
The butter brings a mellow, creamy richness, while garlic adds savory depth and lemon juice keeps every bite fresh. Parsley contributes color and a clean herbal note, so the finished dish tastes balanced rather than overly rich.
It is also flexible enough for different shopping lists. Cod has large, tender flakes, tilapia cooks quickly, haddock has a delicate flavor, and halibut offers a firm, substantial bite. Choose fillets that are about ¾–1 inch thick and roughly 5–6 ounces each so they cook at a similar pace.

Ingredients You’ll Need
Start with four white-fish fillets totaling about 1½ pounds or 680 grams. Cod, haddock, pollock, tilapia, and halibut are all suitable choices, as are other firm white fish with evenly thick fillets.
- Fish: Four fillets, approximately 5–6 ounces each.
- Seasoning: ½ teaspoon fine salt and ¼ teaspoon black pepper.
- Optional flour: ¼ cup or 30 grams all-purpose flour for a delicate, lightly crisp coating.
- For the skillet: 1 tablespoon olive oil and 4 tablespoons unsalted butter, divided.
- For the sauce: Four finely minced garlic cloves, 2 tablespoons fresh lemon juice, and 2 tablespoons chopped fresh parsley.
- For serving: Lemon wedges.
The flour is optional rather than essential. Leaving it out gives you a clean pan-seared fish, while using it creates a light crust that helps the sauce cling to the surface.
Prepare the garlic, lemon juice, and parsley before the fish enters the skillet. Since the sauce cooks in less than a minute, having everything ready prevents overcooking the garlic while you search for ingredients.

How to Make It Step-by-Step
Step 1: Pat the fillets thoroughly dry with paper towels, including the edges. Season both sides evenly with the salt and pepper, then lightly dredge them in flour if you want a delicate crust, shaking off every bit of loose excess.
Step 2: Place a large skillet over medium-high heat and add the olive oil along with 1 tablespoon of the butter. Wait until the butter melts and the pan is hot, but do not let the butter smoke before adding the fish.
Step 3: Arrange the fish in the skillet with space between the fillets. Cook the first side for approximately 3–4 minutes without moving the fish too often, allowing the surface to develop light browning and the fish to release more easily.
Step 4: Carefully turn each fillet with a wide spatula and cook the second side for 2–4 minutes. The exact time depends on thickness, so check that the center flakes easily and reaches 145°F / 63°C internally before transferring the fish to a plate.
Step 5: Reduce the skillet heat to medium and add the remaining 3 tablespoons of butter. Once it has melted, add the minced garlic and cook for about 30–60 seconds, stirring gently until fragrant but not brown.
Step 6: Stir the lemon juice and chopped parsley into the warm garlic butter. Spoon the sauce generously over the fish, add lemon wedges to the plate, and serve immediately while the fillets are tender and the sauce is glossy.
Chef’s Tips for Tender, Flavorful Fish
Drying the fish is one of the most important small steps in this recipe. Moisture on the surface can cause the fillets to steam instead of sear, which makes browning more difficult and may leave the fish less appealing.
Do not crowd the skillet. If the fillets are pressed tightly together, the pan temperature can drop and the fish may cook unevenly. Use a large skillet, or cook in batches if necessary, though a single batch is ideal for this four-serving recipe.
Garlic should go into the pan only after the fish has been removed and the heat has been lowered. It needs just 30–60 seconds to become fragrant, and browned garlic can turn bitter quickly.
For thick fillets, an instant-read thermometer is the most dependable way to judge doneness. The fish can be removed at about 140–145°F / 60–63°C, with the final target being 145°F / 63°C internally.
A pinch of paprika or red-pepper flakes can be added to the salt and pepper if you want gentle warmth. You can also swap the parsley for cilantro, dill, or chives while keeping the same quantity.
What to Serve with Garlic Butter Fish
This saucy fish pairs well with foods that can catch every last drop of lemon butter. Steamed rice, couscous, mashed potatoes, or crusty bread are all practical choices for a satisfying plate.
For vegetables, try steamed broccoli, green beans, asparagus, peas, or a crisp green salad. The fresh vegetable flavors provide contrast to the buttery sauce without requiring another complicated recipe.
A light pasta or simple roasted potatoes can turn the fish into a more filling dinner. Keep the side dishes modestly seasoned so the garlic, lemon, and parsley remain the main flavors.
If you are planning a larger family meal, serve this fish before a fruity dessert such as an easy no-bake pineapple pie. Its cool, bright flavor follows the warm skillet dinner nicely.
Storage, Reheating, and Make-Ahead Notes
This fish is best served immediately because the sauce is freshest and the fillets are at their most tender right after cooking. If you have leftovers, let them cool, place them in an airtight container, and refrigerate them promptly.
Reheat leftovers gently in a skillet over low to medium heat with a small spoonful of water or extra butter. Cover the pan briefly to warm the fish through without drying it out, and avoid prolonged high heat.
You can prepare the sauce ingredients ahead by mincing the garlic, chopping the parsley, and measuring the lemon juice. Season and cook the fish close to serving time for the best texture.
When serving leftovers, add a fresh squeeze of lemon just before eating. The flavor will taste brighter, and a little freshly chopped parsley can refresh the appearance.

Easy Variations for Every Dinner
The simplest variation is to omit the flour and pan-sear the seasoned fillets directly in the olive oil and butter. This version has a softer exterior and is especially good when you want the clean flavor of the fish and sauce to stand out.
For a little extra color and spice, add a pinch of paprika or red-pepper flakes to the salt and pepper. Add the spice before cooking so it lightly coats the fish rather than sitting only in the finished sauce.
Herb changes are an easy way to suit the rest of your meal. Dill works beautifully with lemon and delicate fish, cilantro adds a lively flavor, and chives provide a mild onion note.
If you are feeding people with different preferences, keep the base sauce mild and place extra lemon wedges and red-pepper flakes on the table. That way, everyone can adjust the brightness or heat of their portion.
