Baked Tilapia Whole Fish with Garlic and Herbs

Fresh tilapia, garlic, and herbs come together in the easiest way when you bake the fish whole. The skin keeps the flesh tender, while lemon and herbs perfume every bite. It’s the kind of dish that feels special without much effort.

If you’re ready to get cooking, you can scroll straight down to the recipe card, or use the table of contents to skip to the section you need. Either way, this baked whole tilapia recipe will walk you through each step simply.

Ingredients You’ll Need

Here’s a clear ingredient list with enough detail to make shopping and prepping easy:

• 2 whole tilapia (1.5–2 lb each), cleaned, scaled, and gutted
• 3 cloves fresh garlic, finely minced or pressed
• 2 tablespoons fresh parsley, chopped (or substitute cilantro if preferred)
• 1 tablespoon fresh cilantro, chopped (optional, can combine with parsley)
• 1 medium lemon, zest finely grated and cut into thin slices
• 2 tablespoons olive oil
• 2 tablespoons unsalted butter, softened to room temperature
• 1 teaspoon paprika (regular or smoked for deeper flavor)
• 1 teaspoon Dijon mustard (optional, for a slight tang in the paste)
• 1 teaspoon kosher salt, or to taste
• ½ teaspoon freshly ground black pepper
• Extra sprigs of parsley or cilantro for stuffing the cavity and garnish
• Optional aromatics for baking dish: sliced onion, extra lemon rounds, or herb sprigs for flavoring the pan juices

Step-by-Step Instructions

Step 1: Preheat and Prepare the Pan

Set your oven to 400°F (205°C). Line a baking dish or sheet pan with foil for easier cleanup. Lightly brush the foil with olive oil. If you’d like extra flavor, lay down a few onion slices or lemon rounds to act as a bed for the fish.

Step 2: Dry and Score the Fish

Pat the whole tilapia completely dry with paper towels. Use a sharp knife to make 3 shallow diagonal slits on each side of the fish. This helps the seasoning soak in and ensures even cooking.

Step 3: Make the Garlic-Herb Paste

In a small bowl, mix softened butter, olive oil, minced garlic, chopped parsley, cilantro, lemon zest, paprika, salt, and pepper. If you want a little tang, stir in Dijon mustard. Blend until it forms a fragrant paste.

Step 4: Season and Stuff the Fish

Rub the garlic-herb paste all over the outside of the tilapia, into the slits, and inside the cavity. Stuff the cavity with lemon slices and fresh herb sprigs. Drizzle a bit more olive oil and lemon juice on top to lock in flavor.

Step 5: Bake and Broil to Finish

Place the fish in the prepared pan. Cover loosely with foil and bake for 20–25 minutes, depending on size. Remove foil and switch to broil for 3–5 minutes until the skin is crisp and golden. The fish is ready when the flesh flakes easily and reaches 145°F (63°C) at the thickest part.

Step 6: Rest and Serve

Let the baked tilapia rest for 5 minutes before serving. Transfer to a platter, spoon over pan juices, add a final squeeze of lemon, and garnish with fresh herbs.

Storage & Make-Ahead Tips

• Make-Ahead Prep: You can clean, score, and season the tilapia up to 12 hours ahead. Wrap it tightly with plastic wrap and refrigerate until ready to bake. When it’s time, simply pop it in the oven.
• Storing Leftovers: Once cooled, store the baked tilapia in an airtight container in the refrigerator for up to 3 days. If possible, remove the fish meat from the bones first for easier reheating.
• Freezing: Flake the cooked fish off the bones, let it cool completely, then store in freezer bags for up to 2 months. Perfect for tossing into tacos, pasta, or rice bowls later.
• Reheating: Warm leftovers in the oven at 275°F (135°C), covered with foil and with a splash of broth or water to keep the fish moist. Heat until just warmed through (about 15 minutes). Avoid the microwave, which can dry out the fish quickly.
