You’ll need:

  • 1½ pounds of tilapia fillets
  • 4 tablespoons olive oil
  • 4 tablespoons lemon juice
  • 2 teaspoons garlic powder, divided
  • 2 teaspoons salt, divided
  • 1 teaspoon onion powder
  • 1 teaspoon dried thyme
  • 1 teaspoon dried oregano
  • 1 teaspoon paprika

SUBSTITUTIONS AND ADDITIONS

OLIVE OIL: If you don’t have olive oil on hand, you could also use vegetable oil in a pinch.

PAPRIKA: Smoked paprika would also add a bold smoky flavor to this grilled tilapia if you have it on hand. 

LEMON PEPPER: Lemon pepper would be a tasty addition to your seasoning mix and give your fish a bit of tangy flavor.

FISH: Fresh is ideal, but grilling frozen tilapia works fine. Just make sure your tilapia is fully thawed before placing it in the marinade. It’s best to let your fish thaw in the fridge overnight before grilling for the best results. You could also substitute any mild white fish fillets in its place, such as haddock or cod.

How To Make This Grilled Tilapia Recipe

STEP ONE: Place tilapia in a bowl or sealable plastic bag. Make the marinade by combining olive oil, lemon juice, 1 teaspoon of garlic powder, and 1 teaspoon of salt. Pour over the tilapia and marinate for 30 minutes to an hour, turning halfway through. This will make sure the flavor is evenly distributed.

OUR RECIPE DEVELOPER SAYS

Grill plates can also be used if your grill bars are too far apart for small fillets.

STEP TWO: Prepare your outdoor grill by lightly oiling the cooking grates so your fish won’t stick. Heat the grill to high heat, about 450ºF to 500ºF.

PRO TIP:

Don’t skip oiling the grill grate as you want to make sure to keep the fish from sticking and pulling off all your flavor.

STEP THREE: In a small bowl, make the spice blend by combining the remaining garlic powder, onion powder, dried thyme, oregano, paprika, and the remaining 1 teaspoon of salt. Making your own seasoning mix is so much better than buying a store-bought mix!

PRO TIP:

If you plan to make this recipe regularly, you can make up a big batch of the seasoning mix and store it in the cupboard for next time.

STEP FOUR: Place fish on a plate and pour the remaining marinade over the fish. Sprinkle the seasoning mix on one side of the fish. If you season the fish on both sides, it will overpower the fish.

STEP FIVE: Place fish diagonally across the cooking grates, seasoned side up. Grill for about 4 minutes, turning when the fish begins to pull away from the grate. Turn and grill for about 4 minutes on the other side or until the fish begins to flake.

How To Serve

Storage

MARINATING: If you don’t have time to marinate while you prepare the rest of the meal, you can always place the fish in the marinade in a sealed container in the fridge overnight before cooking the recipe the next day.

IN THE FRIDGE: Grilled tilapia is best eaten the day you cook it but if you have leftovers, you can keep them in the fridge for a day or two.

IN THE FREEZER: You can freeze cooked tilapia for up to 1 month. Thaw and use in salads or casseroles.

REHEATING: Grilled tilapia can get a little dry when you try to reheat it, so it’s best to eat it fresh. If you need to reheat leftovers, it’s best to microwave them in a mostly sealed container to allow the steam to keep them moist while it warms. Use a little lemon juice to help refresh it if needed as well.
