Baked Lemon Garlic Butter Fish
Ingredients
For the Fish:
- 4 fillets of white fish cod, tilapia, haddock, or halibut
- 2 tablespoons olive oil or melted butter
- 2 tablespoons fresh lemon juice
- 2 teaspoons minced garlic
- 1 teaspoon salt
- ½ teaspoon black pepper
- 1 teaspoon smoked paprika for color and flavor
- ½ teaspoon dried oregano or thyme
For the Topping (Optional but Delicious!):
- ¼ cup grated Parmesan cheese
- ¼ cup panko breadcrumbs for extra crispiness
- 2 tablespoons melted butter
For Garnish:
- Lemon slices
- Fresh parsley chopped
Instructions
- Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease a baking dish to prevent sticking.
- Pat the fish fillets dry with a paper towel to remove excess moisture. This helps the seasonings stick better and ensures the fish bakes evenly.
- In a small bowl, mix together olive oil, lemon juice, minced garlic, salt, pepper, paprika, and oregano. Brush this mixture evenly over both sides of each fillet.
- For extra texture, mix Parmesan cheese, panko breadcrumbs, and melted butter in a separate bowl. Sprinkle this mixture over the fillets.
- Place the fillets in a single layer on the prepared baking sheet. Bake for 12-15 minutes, depending on thickness. The fish is done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C).
- Garnish with fresh parsley and lemon slices. Serve immediately with roasted vegetables, rice, or a fresh salad.
Notes
- Best Fish to Use: This recipe works well with white fish fillets like cod, tilapia, haddock, or halibut. Choose fresh or properly thawed frozen fish for the best texture and flavor.
- How to Prevent Dry Fish: Overbaking can make the fish dry. To keep it moist and flaky, bake until the internal temperature reaches 145°F (63°C) or until it flakes easily with a fork.
- Substituting Buttery Flavor: If you prefer a dairy-free option, replace butter with extra virgin olive oil or avocado oil for a lighter version.
- Enhancing the Flavor: Fresh lemon juice and minced garlic add brightness, but you can also sprinkle a little Old Bay seasoning, Cajun spice, or Italian seasoning for extra flavor.
- Making It Crispy: For a crunchy topping, add panko breadcrumbs and Parmesan cheese before baking. This creates a delicious golden crust.
- Baking Alternative: If you want a slightly firmer texture, you can broil the fish for the last 2-3 minutes to get a lightly crisped top.
- Meal Prep Tip: This dish is perfect for meal prep. Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350°F for 5-7 minutes to maintain crispiness.
