Prepared mashed potatoes, corn and cheddar form the base of this chicken-tender casserole. Cook or reheat the breaded chicken according to its own instructions before assembling the final bake. Add the gravy at serving so the breading has less time to soften.
Some are fully cooked and others are raw despite looking browned. Read the label and cook raw products fully to 165°F before adding them to this casserole. Follow package directions for reheating cooked products, too; the assembled bake is not a substitute for those instructions.
Ingredient amounts and preparation
- Set out: 5-6 cups mashed potatoes, homemade or store-bought
- Set out: 1 cup corn
- Set out: 1 cup cheddar cheese, freshly grated
- Set out: 8 breaded chicken tenders, cooked or reheated separately according to their package before assembly
- Set out: Brown gravy, prepared or from a packet
Cooking sequence and doneness
- Stage 1
- Read the chicken-tender label and cook or reheat the eight tenders separately as directed, checking raw poultry reaches 165°F.
- Stage 2
- Heat the oven to 400°F for the casserole stage.
- Stage 3
- Warm five to six cups of prepared mashed potatoes and spread in a 9-by-13-inch baking dish.
- Stage 4
- Drain canned corn if used, or prepare frozen corn according to its package. Scatter the corn and grated cheddar over the potatoes.
- Stage 5
- Cut the cooked chicken on a clean board if desired and arrange it on top.
- Stage 6
- Bake uncovered, starting to check after fifteen minutes, until the center of the potato mixture reaches 165°F.
- Stage 7
- Prepare the gravy separately according to its package or your already prepared gravy’s reheating instructions.
- Stage 8
- Remove the casserole carefully and serve promptly. Add hot gravy to individual portions or drizzle over the dish just before serving.
Warm refrigerated mashed potatoes first and spread them evenly in the dish. A deep layer of cold mash takes longer to heat than the cheese takes to melt. Check the middle of the assembled dish with a thermometer before serving.
When should the chicken be cut?
Cut cooked, safely heated tenders on a clean board if smaller pieces are wanted. Do not leave frozen tenders out to soften just so a knife can go through them. Whole cooked tenders can also be arranged on top. Warm gravy softens breading quickly. Serve it in a jug or spoon it over individual portions after baking. Prepare packet gravy with the water quantity on its package; the amount poured over the casserole is a serving preference.
Can the casserole be assembled in advance?
Keep the potato base and chicken separate until the final heating when practical. That reduces moisture transfer into the breading. If starting with refrigerated components, allow additional heating time and still use 165°F at the center as the endpoint.
Storage and serving later
Refrigerate perishable leftovers promptly in shallow containers at 40°F or below; do not wait for a large hot batch to cool completely on the counter. University of Illinois Extension’s leftover guidance gives a three-to-four-day refrigerated window and 165°F for reheating foods served hot. Keep cold salads and toppings chilled, and follow shorter product-label limits where applicable.
