Step-by-Step Instructions
Step 1: Preheat the Oven
- Preheat your oven to 400°F (200°C).

Step 2: Prepare the Garlic Butter Sauce
- In a small mixing bowl, combine the melted butter, minced garlic, lemon juice, lemon zest, dried parsley, paprika, salt, and black pepper.

Step 3: Season the Tilapia

Step 5: Broil for Extra Flavor (Optional)
- If you like a slightly golden top, switch your oven to broil for the last 2-3 minutes.
- Keep a close eye to avoid burning.
Step 6: Garnish and Serve
- Remove from the oven and let rest for a minute or two.
- Garnish with chopped fresh parsley and serve with lemon wedges on the side.
- Plate with your favorite sides like fluffy rice, creamy mashed potatoes, or crisp roasted veggies.

Customize the Herbs – Try adding dill, thyme, or Italian seasoning for a different flavor twist.
Add Veggies – Bake with thin slices of zucchini, tomatoes, or bell peppers for a complete one-pan meal.
Serve Immediately – Tilapia tastes best fresh out of the oven.
