Ingredients
- Tilapia fillets: choose firm fillets without a fishy smell for best taste
- Butter: adds richness and helps the seasonings stick to the fish
- Lemon zest and lemon juice: for a fresh tangy flavor always use fresh lemons for the brightest flavor
- Garlic salt: boosts savory flavor with a touch of garlic
- Paprika: brings gentle smokiness and gorgeous color sweet paprika is best here
- Freshly ground pepper: brings gentle heat
- Fresh parsley chopped: for a fresh vibrant finish choose curly leaf if possible for more texture
Step-by-Step Instructions
- Prepare the Tilapia:
- Pat each fillet dry with a paper towel and arrange them in a single layer in a fifteen by ten inch baking pan. This prevents excess moisture and ensures the fish bakes evenly.
- Make Lemon Butter:
- Melt butter in the microwave until just melted not bubbling. Stir in both the grated lemon zest and the lemon juice. This lemon butter will infuse the fish with flavor while keeping it moist.
- Season the Fish:
- Drizzle the melted lemon butter mixture evenly over all the tilapia fillets. Sprinkle garlic salt paprika and black pepper evenly across the top of each piece for full coverage and balanced flavor. A light and even coating ensures every bite is tasty.
- Bake the Tilapia:
- Move pan to a preheated four hundred twenty five degree oven. Bake the fillets uncovered for ten to twelve minutes. Check the thickest part of a fillet with a fork It should flake easily and be opaque in color. Do not overbake or the fish can dry out.
- Garnish and Serve:
- Right after baking sprinkle the chopped parsley over the hot fillets. The herbs will wilt slightly from the heat and release their aroma. Serve immediately with extra lemon wedges if you like extra zing.

My favorite part of this dish is the punch of flavor fresh lemon zest brings. I always remember my youngest daughter trying to help zest the lemon for the first time and laughing when a curly peel danced across the counter.
