A Little Story About Tilapia

I first made this for my grandson. He said he didn’t like fish. But he loved this tilapia and roasted vegetables. He asked for seconds! Now it’s his favorite meal when he visits. That makes my heart so happy. *Fun fact*: Tilapia is one of the oldest farmed fish in the world. People have been eating it for thousands of years! So you’re enjoying a little bit of history on your sheet pan.

Making Your 30 Minute Tilapia Recipe

The trick is the marinade. Just mix oil, lemon, and spices in a bowl. Rub it all over the fish. Let the fish sit with it while you chop. Those flavors soak right in. Then pile your veggies on the pan. Give them a little oil and salt. Push them to the sides. Place your sheet pan baked tilapia in the middle. In it goes for about 15 minutes. Do you prefer broccoli or green beans with your fish?

Great for Meal Prep Too

This is a wonderful meal prep tilapia idea. You can chop the veggies ahead of time. Keep them in a bag in the fridge. The marinade can wait in a jar. Then dinner comes together in a flash. Leftovers are great for lunch the next day. Just warm them up gently. The flavors are even better. This roasted vegetables recipe works with many veggies. Have you ever tried meal prepping before?
