This Chicken Potato Broccoli Casserole is my answer to busy nights when comfort food is the only thing that will do. It brings together tender chicken, hearty potatoes, and vibrant broccoli all tucked under a cheesy, golden crust. With every bite, you get warmth, nutrition, and that classic home-cooked satisfaction that only casseroles deliver.
I whipped this up one week when my fridge was nearly empty yet everyone was hungry and cranky. Now it’s in my regular rotation because it always gets requests for seconds and even picky eaters clear their plates.

Storage Tips
Keep leftovers in a sealed container in the fridge for three to four days. Reheat portions in the oven for crispiness or use a microwave for lunches. For longer storage freeze in single portions and thaw overnight for an easy meal later.
Ingredient Substitutions
If you do not have chicken breast use chicken thighs or diced rotisserie chicken for more flavor and tenderness. The potatoes can be replaced with sweet potatoes or cauliflower for a twist. Out of cheddar cheese blend mozzarella or pepper jack into the mix for a new flavor profile.
Serving Suggestions
Serve this casserole straight from the dish alongside a crisp green salad or roasted carrots. It also makes a filling lunch for meal prep. Crumble bacon or a handful of crispy onions on top for those who love extra crunch.
