A one-pot Chicken recipe with Mexican flavors, built for busy weeknights when you want real food without a sink full of dishes. Comes together in roughly 43 minutes, serves about 4, and uses ingredients you can find at any normal grocery store. The technique is simple: build a base in your pot, layer in the main ingredients, simmer until everything has had time to talk to each other, and serve straight from the pan. If you're cooking for picky eaters, this one tends to land — the flavors are recognizable, the texture is comforting, and there's nothing weird hiding in the ingredient list. Perfect for the kind of evening where you want dinner on the table by 7pm and the kitchen empty by 7:30.

Step-by-step instructions

Cut each chicken breast in about 3 pieces, so that it cooks faster and put it in a small pot. Pour Enchilada sauce over it and cook covered on low to medium heat until chicken is cooked through, about 20 minutes. No water is needed, the chicken will cook in the Enchilada sauce. Make sure you stir occasionally so that it doesn't stick to the bottom.
Remove chicken from the pot and shred with two forks.
Preheat oven to 375 F degrees.
Start layering the casserole. Start with about ¼ cup of the leftover Enchilada sauce over the bottom of a baking dish. I used a longer baking dish, so that I can put 2 corn tortillas across. Place 2 tortillas on the bottom, top with ⅓ of the chicken and ⅓ of the remaining sauce. Sprinkle with ⅓ of the cheese and repeat starting with 2 more tortillas, then chicken, sauce, cheese. Repeat with last layer with the remaining ingredients, tortillas, chicken, sauce and cheese.
Bake for 20 to 30 minutes uncovered, until bubbly and cheese has melted and started to brown on top.
Serve warm.

Why this works on a weeknight

Chicken Enchilada Casserole lands at about 37 minutes total — a little longer than our 30-minute target, but most of that time is hands-off simmering, which is why it earned a spot in our Sheet-Pan Dinners collection. The technique is forgiving, the ingredient list is grocery-store standard, and the active cooking time is short enough that you can answer a text message in the middle without ruining dinner.

Cleanup notes

This is a single-pan recipe, so the cleanup is exactly one pan, one cutting board, and one knife. While the dish rests, fill the pan with hot soapy water — by the time you are done eating, the residue lifts off with a single pass of a sponge. Skip the steel wool on cast iron; a stiff brush and warm water are all you need to keep the seasoning intact.

Make-ahead and leftovers

Leftovers keep covered in the fridge for up to three days. Reheat in a dry pan over medium-low with a splash of water or stock to loosen the sauce. Chicken Enchilada Casserole actually improves overnight as the flavors keep talking to each other, so doubling the recipe and packing tomorrow's lunch is a high-leverage weeknight move.
