Ingredients You’ll Need
Before we dive into the step-by-step guide, here’s what you’ll need for this easy oven-baked whole tilapia recipe:
- 1 whole tilapia fish (cleaned and scaled, about 1–1.5 lbs)
- 2 tablespoons butter (melted)
- 3 cloves garlic (minced)
- 1 lemon (sliced)
- 1 tablespoon olive oil
- Salt and black pepper (to taste)
- Fresh herbs (like parsley or cilantro)
- Optional: paprika or chili flakes for a mild kick
Step-by-Step: How to Make Garlic Butter Whole Tilapia
1. Preheat the Oven
Set your oven to 400°F (200°C) so it’s ready for baking once you’ve prepped your fish.
2. Clean and Score the Fish
Pat the tilapia dry with paper towels. Use a sharp knife to make 2–3 diagonal cuts on each side. This helps the seasoning soak in better.
3. Season Generously
Rub olive oil, salt, and pepper all over the fish — including inside the cavity. Then, mix melted butter with minced garlic and brush it thoroughly over the entire fish.
4. Add Lemon and Herbs
Stuff a few lemon slices and fresh herbs into the fish cavity. This infuses the fish with a citrusy aroma while keeping it moist during baking.
5. Bake to Perfection
Place the fish on a lined baking sheet or foil. Bake for 20–25 minutes, depending on size, until the skin is golden and the meat flakes easily with a fork.
6. Optional: Broil for Crispiness
If you love crispy skin, broil for an additional 2–3 minutes — but keep an eye on it to avoid burning.
