Ingredients and Tools
Ingredients
- 4 fresh tilapia fillets
- 2 tablespoons olive oil or melted butter
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon garlic powder
- 1 teaspoon paprika
- 1 lemon (sliced into wedges)
- Optional: fresh parsley or dill for garnish
Tools
- Big Green Egg grill
- Fish basket or grill mat
- Meat thermometer
- Long-handled tongs or spatula
- Basting brush
Gathering these ingredients and tools ahead of time will make the grilling process seamless and enjoyable.
Preparing the Big Green Egg
Step 1: Setting up the Grill
Start by filling the Big Green Egg with natural lump charcoal. This type of charcoal burns cleanly and provides a mild, smoky flavor that enhances the tilapia. Light the charcoal using a fire starter or chimney starter and wait until it burns evenly. Avoid lighter fluid to prevent chemical odors.
Step 2: Adjusting the Temperature
Once the charcoal is burning, adjust the airflow vents to maintain a medium heat of 350–375°F (177–190°C). If you’re using indirect grilling, place the convEGGtor (ceramic heat deflector) inside the grill to prevent direct heat from scorching the fish.

Step 3: Prepping the Grill Grates
Clean the grates thoroughly with a grill brush to remove any residue. Then, use a paper towel dipped in oil to lightly grease the grates. This step helps prevent the tilapia from sticking.
Preparing the Tilapia
Step 1: Cleaning and Seasoning
Rinse the tilapia fillets under cold water and pat them dry with a paper towel. Drying the fish ensures that the seasonings adhere well and that it sears properly on the grill.
Brush both sides of the fillets with olive oil or melted butter to keep them moist and to enhance browning. Sprinkle salt, pepper, garlic powder, and paprika evenly over both sides of the fish. These seasonings bring out the natural flavors of the tilapia without overpowering its mild taste.
Step 2: Optional Marinade
If you’d like to add an extra layer of flavor, consider marinating the tilapia for 15–20 minutes in a citrus-based marinade made of lemon juice, minced garlic, olive oil, and a touch of honey. Avoid marinating for too long, as the acid can break down the delicate fish.
Step 3: Preparing for Grilling
Place the fillets in a fish basket or on a grill mat. This will make flipping easier and help prevent the fish from sticking to the grill.
Grilling the Tilapia
Step 1: Placing the Fish on the Grill
Once the Big Green Egg has reached the desired temperature, carefully place the tilapia on the grill. If the fillets have skin, place them skin-side down first. The skin acts as a barrier, helping the fish hold together as it cooks.
Step 2: Grilling Time
Grill the tilapia for 3–5 minutes on the first side. Use long-handled tongs or a spatula to gently flip the fish and cook for another 3–5 minutes on the other side. The exact timing depends on the thickness of the fillets.
Step 3: Checking for Doneness
To ensure the tilapia is fully cooked, use a meat thermometer to check the internal temperature. It should reach 145°F (63°C). Additionally, the flesh should appear opaque and flake easily with a fork.
Serving Suggestions
Step 1: Plating
Transfer the grilled tilapia to a serving platter and garnish with fresh parsley or dill. Add lemon wedges on the side for a bright, citrusy kick.
Step 2: Pairing with Sides
Grilled tilapia pairs wonderfully with a variety of sides. Consider serving it with:
- Grilled vegetables like zucchini, asparagus, or bell peppers.
- A light and fluffy rice pilaf.
- A fresh green salad with a tangy vinaigrette.
Step 3: Sauce Ideas
Enhance the flavor with a simple sauce. Options include:
- Tartar sauce for a creamy, tangy complement.
- Garlic butter sauce for a rich and indulgent touch.
- Lemon-dill sauce for a fresh and herbaceous finish.
Tips for Perfect Grilled Tilapia
- Prevent sticking: Always oil the grill grates or use a grill mat or fish basket.
- Avoid overcooking: Tilapia cooks quickly, so keep an eye on the grill and use a thermometer for accuracy.

- Maintain steady heat: Consistent grill temperature is key to evenly cooked fish.
