On a large rimmed sheet pan spread out the green beans on one end and line up your tilapia filets on the other end of the pan. Drizzle or spoon the melted butter mixture over the green beans and spread over the tilapia with the back of a spoon or a cooking brush. Season green beans and tilapia with a sprinkle of salt and pepper.
Place pan into the oven and bake for 15 minutes. Remove from oven and make sure the fish has reached the appropriate internal temperature, mine was 130 for the tilapia.
1. I like to cut my tilapia filets in half long ways, I find it helps them to cook more evenly.
2. This recipe could easily be doubled, but making much more than that and you might need to use 2 cookie sheets to ensure the fish isn't crowded and is able to cook thoroughly.
3. I like to use green beans in this recipe because I find 15 minutes is the perfect amount of time for them. But you could easily swap out the vegetables in the recipe, Ooh, asparagus would probably be delicious. Depending on how tender you like your broccoli, that might work as well. But I would stay away from potatoes as they would need a longer cook time and your fish would be overdone.
