Ingredients (Baked Fish Fillets Recipe)
To make about 4 servings of perfectly baked fish, you’ll need:
- 4 fish fillets (about 5–6 ounces each; cod, tilapia, haddock, or halibut all work well)
- 2 tablespoons olive oil (or melted butter for richer flavor)
- 2 tablespoons lemon juice (freshly squeezed is best)
- 2 garlic cloves, minced
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon paprika (optional, for color and mild smokiness)
- 1 teaspoon dried parsley (or 1 tablespoon fresh parsley, chopped)
- 1 teaspoon dried thyme or oregano (optional, for an herby note)
- 1 tablespoon grated Parmesan cheese (optional, for a savory finish)
- Lemon wedges, for serving
Step-by-Step Instructions for Baked Fish Fillets
Step 1: Preheat Your Oven
Set your oven to 400°F (200°C). This temperature ensures the fish cooks quickly while staying moist and tender. Line a baking sheet with parchment paper or lightly grease it with oil to prevent sticking.
Step 2: Prepare the Marinade
In a small bowl, whisk together the olive oil, lemon juice, garlic, salt, pepper, paprika, and parsley. This mixture adds brightness and depth of flavor without overpowering the natural taste of the fish.
Step 3: Season the Fish
Pat the fish fillets dry with a paper towel—this step helps the seasonings stick better. Place the fillets on your prepared baking sheet, then brush or drizzle the marinade evenly over them. Make sure both sides are coated for maximum flavor.
Step 4: Bake the Fish
Place the tray in the preheated oven and bake for 12–15 minutes, depending on the thickness of your fillets. A general rule is to bake fish for 10 minutes per inch of thickness. The fish is ready when it flakes easily with a fork and turns opaque.
Step 5: Add a Finishing Touch
For extra flavor, sprinkle a little Parmesan cheese on top during the last 2–3 minutes of baking. You can also switch on the broiler for a minute to give the fillets a lightly golden crust.
Step 6: Serve and Enjoy
Remove the baked fish fillets from the oven and serve immediately with fresh lemon wedges. Pair them with roasted vegetables, steamed rice, or even garlic bread for a complete meal.

Tips for Perfect Baked Fish Fillets
- Choose Fresh Fish – Look for fillets that are firm, with no strong odor. Frozen fillets also work well—just be sure to thaw them completely and pat them dry before seasoning.
- Don’t Overbake – Fish cooks quickly, so keep an eye on it. Overcooking can make it dry. Use a fork to test flakiness after 12 minutes.
- Line the Pan – Using parchment paper or foil makes cleanup easy and prevents sticking.
- Season Generously – Since fish is naturally mild, don’t be afraid to use herbs, spices, and citrus for extra flavor.
- Add a Crunchy Topping – Mix breadcrumbs with olive oil and herbs, then sprinkle on top before baking for a crispy finish.
Variations to Try
One of the best things about making Baked Fish Fillets is how easily you can adapt the recipe to suit your taste or what you have in your kitchen. With just a few swaps, you can completely change the flavor profile while still enjoying the same tender, flaky results. Here are some delicious twists you’ll love trying:
Garlic Butter Baked Fish Fillets
For a richer, more indulgent version, replace the olive oil with melted butter and add an extra clove of garlic. The butter infuses the fish with a nutty depth of flavor, while the garlic adds a comforting aroma. This variation is perfect if you’re serving your Baked Fish Fillets with mashed potatoes or crusty bread to soak up the buttery goodness.
Mediterranean Style
Give your dish a sunny, Mediterranean flair by topping the fillets with sliced cherry tomatoes, briny black olives, and a sprinkle of feta cheese before baking. The combination of sweet tomatoes, salty cheese, and tender fish creates a colorful and vibrant plate that’s both healthy and satisfying. Pair with a side of couscous or a Greek salad for a complete meal.
Spicy Cajun Baked Fish Fillets
If you love bold flavors, coat your fish with Cajun seasoning instead of the usual paprika and parsley. The smoky, slightly spicy kick transforms ordinary Baked Fish Fillets into a dish full of southern charm. Serve with corn on the cob or dirty rice for a true Cajun-inspired dinner.
Asian-Inspired Baked Fish Fillets
For a fresh twist, whisk soy sauce, sesame oil, and grated ginger into your marinade. This Asian-inspired take adds tangy, savory, and slightly nutty flavors that complement the mildness of the fish beautifully. Top with green onions or sesame seeds before serving for extra flair.
Creamy Parmesan Crust
If you’re in the mood for something decadent, mix mayonnaise, Parmesan cheese, and breadcrumbs, then spread a thin layer over each fillet before baking. The topping bakes into a golden, cheesy crust that makes the fish irresistible. This version of Baked Fish Fillets is a crowd-pleaser that pairs especially well with roasted vegetables or a simple pasta side.
Ingredient Substitutions
- Fish: Cod, tilapia, haddock, halibut, sole, or even salmon can be used. Choose what’s freshest or most budget-friendly.
- Olive oil: Can be swapped with avocado oil, butter, or coconut oil depending on your preference.
- Lemon juice: Lime juice makes a good substitute.
- Garlic: Garlic powder works in a pinch if you don’t have fresh cloves.
- Herbs: Try dill, chives, or basil if you’d like a different flavor profile.
Storage Instructions
If you have leftovers (though they disappear quickly), here’s how to store them properly:
- Refrigerator: Store cooled baked fish fillets in an airtight container for up to 3 days.
- Freezer: Place portions in freezer-safe bags or containers and store for up to 2 months. Reheat gently in the oven at 300°F (150°C) until warmed through to avoid drying it out.
- Reheating tip: Avoid microwaving if possible—it can make fish rubbery. The oven or stovetop works better.
Serving Suggestions
Baked fish fillets are incredibly versatile and pair well with many sides. Try serving them with:
- Steamed asparagus or green beans
- Garlic mashed potatoes
- Quinoa or wild rice
- Fresh garden salad
- Roasted sweet potatoes
You can even flake the fish and use it in tacos, wraps, or over pasta for a different spin.
