Key element — don’t overbake

Ingredients
Fish
- 4 tilapia fillets (about 5–6 oz / 140–170g each)
- 1–2 Tbsp olive oil or melted butter
- Salt and black pepper to taste
- ½ tsp garlic powder
- ½ tsp paprika (optional, for color)
Lemon butter topping
- 2–3 Tbsp butter, cut into small pieces
- 2 garlic cloves, minced (or ½ tsp garlic powder)
- 1 lemon, sliced into thin rounds + extra wedges for serving
- 2 Tbsp fresh lemon juice
- 2–3 Tbsp chopped fresh parsley
- Optional: pinch of red pepper flakes
Swaps
- 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.
Instructions
| 1 | 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. |
| 2 | Season the fish. Drizzle the fillets with olive oil or melted butter. Season both sides with salt, pepper, garlic powder, and paprika if using. |
| 3 | 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. |
| 4 | Bake. Bake 12–15 minutes, depending on thickness, until the fish is opaque and flakes easily with a fork. Avoid overbaking. |
| 5 | Finish and serve. Sprinkle with chopped fresh parsley. Serve immediately with extra lemon wedges on the side. |
Pro 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.
