Ingredients
For the Fish
- 4 white fish fillets, about 5–6 ounces each
- 2 tablespoons olive oil
- 2 tablespoons unsalted butter
- 3 cloves garlic, minced
- 1 teaspoon paprika
- ½ teaspoon Italian seasoning
- ½ teaspoon onion powder
- ¼ teaspoon black pepper
- ½ teaspoon salt, or to taste
- 1 tablespoon fresh lemon juice
- 1 teaspoon lemon zest
- 2 tablespoons fresh parsley, chopped
Optional Garnish
- Lemon wedges
- Extra fresh parsley

How to Make White Fish Fillets
1. Prepare the Fish
Pat the fish fillets thoroughly dry with paper towels.
Removing excess moisture helps the fish brown instead of steaming.
Check the fillets for any remaining bones and remove them with clean tweezers if necessary.
2. Season the Fillets
In a small bowl, combine:
- Paprika
- Italian seasoning
- Onion powder
- Black pepper
- Salt
Lightly season both sides of each fish fillet.
Don’t use an excessive amount of seasoning because white fish has a delicate flavor.
3. Heat the Pan
Place a large nonstick or heavy skillet over medium-high heat.
Add the olive oil and allow it to heat for about 30 seconds.
Add the butter and let it melt.
Once the butter is foamy but not burned, you’re ready to cook the fish.
4. Cook the Fish
Carefully place the seasoned fish fillets into the skillet.
Cook for approximately 3–5 minutes on the first side, depending on the thickness of the fillets.
Carefully flip the fish and cook for another 2–4 minutes.
The exact cooking time will vary according to the type and thickness of the fish.
5. Add the Garlic Butter
Reduce the heat to medium-low.
Add the minced garlic around the fish and cook for approximately 30 seconds, stirring gently so the garlic doesn’t burn.
Spoon some of the melted garlic butter over the fish.
Add the lemon zest and fresh lemon juice.
Continue cooking briefly until the fish is cooked through and flakes easily with a fork.
For food safety, fish should reach an internal temperature of 145°F (63°C).
6. Finish With Fresh Herbs
Remove the skillet from the heat.
Sprinkle the fish with freshly chopped parsley.
Add an extra squeeze of lemon just before serving.
The bright lemon flavor helps balance the buttery richness.
How to Tell When White Fish Is Done
White fish cooks quickly, so keeping an eye on it is important.
The fish is generally ready when:
- The flesh becomes opaque.
- It flakes easily with a fork.
- The center is no longer translucent.
- The thickest part reaches 145°F (63°C).
Avoid cooking the fish much longer than necessary because overcooking can make it dry and tough.
Oven-Baked White Fish Fillets
If you’d rather bake the fish, this recipe is just as easy.
Preheat the oven to 400°F (200°C).
Place the seasoned fish in a lightly greased baking dish.
Combine the melted butter, garlic, lemon juice, lemon zest, and herbs, then spoon the mixture over the fillets.
Bake for approximately 12–18 minutes, depending on the thickness of the fish.
Check the thickest part with a food thermometer and remove the fish once it reaches 145°F (63°C).
Air Fryer White Fish
You can also make these fillets in an air fryer.
Preheat the air fryer to 390°F (200°C).
Lightly brush the fish with olive oil and season as directed.
Place the fillets in the basket without overcrowding.
Air fry for approximately 8–12 minutes, depending on thickness, turning carefully if needed.
Finish with lemon juice, melted butter, and parsley.
Tips for Perfect White Fish Fillets
Pat the Fish Dry
This is one of the simplest ways to improve browning.
Don’t Overcrowd the Pan
Leave space between the fillets so heat can circulate properly.
Handle the Fish Gently
White fish can be delicate and may break when flipped. A wide fish spatula makes the job easier.
Use Medium to Medium-High Heat
Very high heat can burn the butter and garlic before the fish is finished.
Don’t Overcook
The biggest mistake with white fish is usually cooking it too long.
A thermometer is the most reliable way to check doneness.
Add Lemon at the End
Adding lemon near the end keeps the flavor fresh and prevents the fish from becoming overly acidic during cooking.
Best Types of White Fish to Use
Several varieties work well with this recipe.
Cod
Cod is mild, flaky, and relatively thick, making it excellent for pan-searing or baking.
Haddock
Haddock has a slightly more distinctive flavor while remaining mild enough for garlic butter and lemon.
Tilapia
Tilapia is delicate, cooks quickly, and works especially well with bold seasonings.
Hake
Hake has a tender texture and mild flavor that pairs beautifully with lemon and herbs.
Pollock
Pollock is another mild white fish that works well in quick weeknight recipes.
Cooking time should always be adjusted according to the thickness of the particular fillets you’re using.
Easy Flavor Variations
Cajun White Fish
Add Cajun seasoning and a pinch of cayenne pepper to the seasoning mixture.
Parmesan Crusted Fish
Mix grated Parmesan with breadcrumbs and sprinkle the mixture over the fish before baking.
Mediterranean Style
Add cherry tomatoes, olives, oregano, parsley, and a little extra lemon.
Creamy Garlic Fish
After removing the fish from the pan, make a quick sauce using butter, garlic, heavy cream, Parmesan, and black pepper.
Return the fish to the sauce just before serving.
Spicy Lemon Fish
Add crushed red pepper flakes or cayenne pepper to the garlic butter.
What to Serve With White Fish
These fillets pair with almost any simple side dish.
Try:
- Roasted potatoes
- Mashed potatoes
- Steamed rice
- Seasoned fried rice
- Roasted vegetables
- Steamed broccoli
- Green beans
- Asparagus
- Garden salad
- Coleslaw
- Garlic bread
- Lemon cucumber salad
For a lighter meal, serve the fish with steamed vegetables and a fresh salad.
Storage and Reheating
Place leftover fish in an airtight container and refrigerate within two hours of cooking.
Use refrigerated leftovers within 3–4 days.
To reheat, place the fish in a covered skillet over low heat with a small splash of water or broth.
Heat gently until warmed through.
You can also use the microwave, but short heating intervals help prevent the fish from becoming rubbery.
Frequently Asked Questions
What is the best white fish for this recipe?
Cod, haddock, tilapia, hake, and pollock all work well. Choose a fresh or properly frozen fillet with a thickness similar to the recipe.
Can I use frozen fish?
Yes. Thaw the fish completely in the refrigerator and pat it very dry before cooking.
Can I make this recipe without butter?
Yes. Use olive oil instead. However, butter provides the rich flavor that makes the garlic-lemon sauce especially delicious.
How long should I cook white fish?
Cooking time depends mainly on thickness. Most average fillets take roughly 3–5 minutes per side in a skillet, but use an internal temperature of 145°F (63°C) as the food-safety guide.
Why does my fish fall apart when I flip it?
White fish can be delicate. Make sure the first side has developed a light crust before flipping, and use a wide spatula to support the entire fillet.
