This baked burrito casserole transforms your wrapped favorites into a no-hassle family dinner. Tender, shredded chicken, airy rice, black beans and sweet corn mix with south-of-the-border seasonings and melted cheese. It's a clever way to enjoy Mexican-inspired flavors without rolling individual burritos. Need something simple for a hectic evening? This filling, mouthwatering meal comes together with minimal effort.
I originally created this when our after-school schedule went bonkers and we needed something that would hold up regardless of when everyone made it to the table. I was shocked when my pickiest eater asked for seconds! Now they request it twice a month, and I always make extra for packed lunches later.
