Start by making a batch of mashed potatoes or reheating leftovers. Spread the mashed potatoes evenly along the bottom of your casserole dish. They act as a creamy base that holds all the delicious toppings.
Next, sprinkle a layer of corn over the mashed potatoes. It adds a pop of sweetness and texture. Grate the cheddar cheese and spread it across the corn, creating a layer that melts beautifully when baked.
If using homemade chicken tenders, slice them into bite-sized pieces. This step makes the casserole easier to serve while ensuring every bite is packed with crispy chicken.
Top the casserole with your chicken pieces, arranging them evenly. Bake the dish in a preheated oven at 400°F for 15-20 minutes, depending on whether you’re using fresh or frozen chicken. The cheese will melt, and the chicken will crisp up during baking.
While the casserole is baking, heat up the brown gravy in a saucepan. Once the casserole is ready, drizzle the gravy over the top just before serving. It’s the finishing touch that ties all the flavors together.
