Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
4 white fish fillets (6 ounces each), such as cod or tilapia
1/4 cup unsalted butter, softened
2 cloves garlic, finely minced
1 teaspoon salt
1/2 teaspoon black pepper
2 tablespoons freshly minced herbs (parsley, oregano, basil, thyme, or dill)
1 lemon, zested and thinly sliced
Directions
Preheat your oven to 350°F (175°C).
Lightly spray a baking dish with cooking spray. Arrange the white fish fillets in a single layer at the bottom of the dish.
Season the fish evenly with a small pinch of salt and black pepper.
In a small bowl, combine the softened butter, minced garlic, 1 teaspoon salt, 1/2 teaspoon black pepper, minced herbs, and lemon zest. Mix until smooth and well blended.
Spread the lemon butter mixture evenly over the top of each fish fillet.
Place thin lemon slices over the buttered fish.
Bake for 15–20 minutes, or until the fish is opaque, tender, and flakes easily with a fork. Cooking time may vary slightly depending on the thickness of the fillets.
Remove from the oven and, if desired, sprinkle with additional fresh herbs before serving. Serve immediately with your favorite side dishes.
Servings and timing
Servings: 4 (1 fillet per serving)
Prep time: 5 minutes
Cook time: 15–20 minutes
Total time: About 20–25 minutes
Use different herbs such as rosemary and thyme for a more earthy flavor, or dill and parsley for a fresher taste.
Add a tablespoon of fresh lemon juice to the butter mixture for extra citrus brightness.
Sprinkle a light layer of grated parmesan cheese on top before baking for a slightly crisp finish.
Add a pinch of paprika or red pepper flakes for mild heat.
Place thin slices of zucchini or cherry tomatoes around the fish in the baking dish to create a complete one-pan meal.
Storage/Reheating
Store leftover fish in an airtight container in the refrigerator for up to 2 days.
To reheat, place the fish in a baking dish, cover loosely with foil, and warm in a 300°F (150°C) oven for about 8–10 minutes, or until heated through. Avoid high heat to prevent drying out.
You can also reheat gently in the microwave in short intervals, though the oven method helps maintain better texture.
Freezing is not recommended, as the texture of baked fish may become watery once thawed.
FAQs
How do I keep fish from drying out while baking?
Spreading a layer of lemon herb butter over the fish helps lock in moisture and protects it from drying out in the oven. Avoid overcooking and remove the fish as soon as it flakes easily.
What types of fish work best for this recipe?
Mild white fish such as cod, tilapia, halibut, haddock, flounder, or snapper all work well.
How do I know when the fish is done?
The fish should turn opaque and flake easily when gently pressed with a fork. The internal temperature should reach 145°F (63°C).
Can I use frozen fish fillets?
Yes, but thaw them completely and pat them dry before baking to prevent excess moisture in the dish.
Can I use salted butter instead of unsalted?
Yes, but reduce the added salt slightly to prevent the dish from becoming too salty.
Can I make this recipe dairy-free?
You can substitute the butter with a dairy-free plant-based alternative that melts well.
What sides go well with lemon butter baked white fish?
Steamed vegetables, roasted potatoes, rice, quinoa, fresh salads, or mashed potatoes all pair nicely.
Can I prepare this ahead of time?
You can mix the lemon butter and store it in the refrigerator for up to 24 hours. Assemble and bake just before serving for the best texture.
Why is my fish watery?
This can happen if the fish was not fully thawed or if it naturally releases moisture while baking. Patting the fish dry before seasoning helps reduce excess liquid.
Can I cook this at a higher temperature?
Yes, you can bake at 400°F (200°C) for about 10–12 minutes, but watch carefully to avoid overcooking.
