Ways to tell if grilled tilapia is done

No one wants to eat undercooked or overcooked fish. Tilapia is a delicate white fish that can be easy to overcook. Use this guide to help you master the art of cooking tilapia on the grill.

1. Touch the fillet

One way to determine if your fish is done cooking is to touch it. Gently poke the fillet with your finger.

When the fish is done cooking, it should have a slightly springy texture and a gentle firmness.

If it’s too soft, give it a few more minutes on the grill. Use your senses and trust the grill to cook your fish perfectly!

2. Use a meat thermometer

Using a meat thermometer to measure the internal temperature of grilled tilapia is simple and straightforward.

Insert the tip of an instant-read thermometer into the thickest part of the fish. The internal temperature should read 145° Fahrenheit.

3. Check the texture

To check the texture of a grilled tilapia fillet to determine its doneness, start by inserting the tines of a fork into the thickest portion of the fish at a 45-degree angle.

Gently twist the fork and pull up some of the fish. If it flakes easily without resistance, the fish is done and ready to eat.

If the fish is undercooked, it will resist flaking and be translucent.

4. Time on the grill.

Grilled tilapia fillets can be cooked in about 4-8 minutes, depending on the thickness of the fillets.

Cook for a few minutes over medium-high heat, turning once during grilling and allowing the other side to grill for an additional few minutes.

Make sure to cook the fish until it flakes easily and reaches a minimum temperature of 145°.
