Kitchen Tools You’ll Need

Whisk
Measuring cups and spoons
Spatula
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 400°F (200°C).
Lightly grease a baking dish with cooking spray or butter to prevent sticking.
Step 2: Prepare the Tilapia
Pat the tilapia fillets dry using paper towels.
This helps the seasoning stick and prevents excess moisture.
Step 3: Arrange the Fish
Place the fillets in a single layer in the baking dish.
If some pieces are thicker, position them around the edges for even cooking.
Step 4: Season the Fillets
Sprinkle evenly with:
Salt
Black pepper
Garlic powder
Onion powder
Paprika (optional)
Drizzle melted butter over the top.
Step 5: Make the Creamy Parmesan Sauce
In a medium bowl, whisk together:
Heavy cream
Mayonnaise
Grated Parmesan cheese
Lemon juice
Dijon mustard (optional)
Minced garlic
Parsley
Mix until smooth and creamy.
Step 6: Coat the Fish
Pour the creamy parmesan mixture over the tilapia fillets.
Spread evenly so each piece is fully coated.
Step 7: Add the Cheese Topping
Sprinkle shredded Parmesan or mozzarella evenly over the top.
This creates a golden, bubbly crust.
Step 8: Bake
Bake for 15–20 minutes, or until:
Fish flakes easily with a fork
Flesh is opaque throughout
Thinner fillets may cook in 12–15 minutes.
Step 9: Optional Broil
For a golden top, broil for 2–3 minutes at the end.
Watch closely to avoid burning.
Step 10: Rest & Serve
Let the dish rest for 3–5 minutes to allow the sauce to thicken.
Serve warm with lemon wedges for a fresh, zesty finish.
