Ingredients
Instructions
- Preheat and prep. Preheat oven to 400°F (200°C). Lightly grease a baking dish or line with parchment. Pat the tilapia fillets dry with paper towels and place them in a single layer in the dish.
- Season the fish. Drizzle the fillets with olive oil or melted butter. Season both sides with salt, pepper, garlic powder, and paprika if using.
- Add lemon and butter. Scatter the minced garlic over the fish. Place a few thin lemon slices and small pieces of butter on top of each fillet. Drizzle with the fresh lemon juice.
- Bake. Bake 12–15 minutes, depending on thickness, until the fish is opaque and flakes easily with a fork. Avoid overbaking.
- Finish and serve. Sprinkle with chopped fresh parsley. Serve immediately with extra lemon wedges on the side.
Notes & Tips
- Pat the fish dry before seasoning so it browns slightly and the seasoning sticks.
- Thicker fillets may need an extra 1–2 minutes; thinner ones cook faster.
- For extra color, broil the last 1 minute while watching carefully.
- This pairs beautifully with asparagus, zucchini, or a simple green salad.
- Leftovers reheat gently in the oven or a covered skillet to avoid drying out.
Variations & serving ideas
- Other fish: Cod, sole, or flounder work well with the same method.
- Dairy-free: Use olive oil or a dairy-free butter alternative.
- Herb variation: Swap parsley for dill, chives, or basil.
- Extra flavor: Add a sprinkle of Parmesan in the last few minutes of baking.
- Garlic-herb version: Add extra minced garlic and a mix of parsley, dill, and chives.
- Parmesan crust: Sprinkle grated Parmesan over the fillets in the last 3–4 minutes of baking.
- Spicy lemon: Add a pinch of red pepper flakes or a dash of cayenne with the seasonings.
- Sheet-pan meal: Add asparagus or zucchini spears around the fish for a complete one-pan dinner.

- Refrigerator: Up to 3 days (Store in an airtight container; reheat gently)
