Store in an airtight container for up to 4 days. To freeze, store in an airtight container for up to 3 months. If you want to make a bigger batch, you can either use a bigger pan or use two separate pans. Just make sure you don’t pile the ingredients on top of each other or it won’t cook evenly or at the correct rate. You shouldn’t have to adjust the amount of cooking as long as everything stays in one layer and not piled. To avoid the chicken from sticking together while cooking, separate the breasts on the sheet pan and put some of the potato and peppers mixture in between them. Do not bake at a lower or higher temperature or it won’t cook properly or turn out looking good. There are quite a few brands of red baby potatoes that turn brown when cooked instead of remaining red. Simply Potatoes was the only brand that remained red enough to look red. I used thinner chicken breasts and not super thick chicken breasts. You may have to adjust the cooking time if the breasts are very thick. Keep an eye on the internal temperature as it should always reach 165 degrees to be finished and safe regardless of the size of the chicken.
