Fire up the grill! This grilled tilapia is deliciously seasoned and has the best flaky texture. Mix a few simple ingredients for the marinade, give it a little time to get super tasty and then it is grilled to perfection in a matter of minutes!
Prepare the marinade by whisking together the lemon juice, olive oil, garlic, black pepper, salt, and mustard powder.
Pour the marinade into a large sealable bag or container and place the tilapia filets into the container. If using frozen be sure they are thawed before you marinate.
Marinate the tilapia 30 minutes to an hour. While the filets are marinating, preheat a grill to 400 degrees Fahrenheit.
Once the tilapia filets are ready, remove them from the marinade. Brush the grill with olive oil and grill the filets for 4-6 minutes per side. The filets should easily come off the grill, if they are sticking give them another 1-2 minutes.
Remove the grilled tilapia from the grill and serve!
