This mashed potato casserole is a family favorite for busy weeknights and cozy Sunday dinners. Layers of creamy potatoes, sweet corn, gooey cheddar, and crispy chicken strips create the ultimate comfort food. A pour of savory brown gravy brings everything together for a fast classic meal that pleases all ages.

I threw this together on a chilly Saturday after a day of errands and everyone cleaned their plates in record time. Now we make it for movie nights and even let the kids help with the toppings.

Ingredients

  • Mashed potatoes The base holds everything together Use starchy potatoes like Russets and whip until fluffy for best texture
  • Corn Adds just the right pop of sweetness and color Use frozen or canned but choose bright yellow kernels for freshness
  • Cheddar cheese Sharp flavor and perfect melt Look for blocks to grate yourself instead of bagged for superior melty results
  • Chicken tenders Crispy and hearty topping You can make your own or use quality store-bought for speed Let them thaw a few minutes for easier slicing
  • Brown gravy Pulls all the flavors together A homemade batch is wonderful but a quality gravy packet works in a pinch Choose low sodium if desired

Step-by-Step Instructions

Prep the Oven
Set your oven to 400 degrees Fahrenheit for even baking
Prepare Chicken
If you use frozen chicken tenders set them out for about five minutes for softer slicing
Layer the Potatoes
Spread the mashed potatoes evenly across the bottom of a nine by thirteen casserole dish Make sure they are warm so they spread smoothly
Add the Corn and Cheese
Scatter the corn evenly over the potatoes Top generously with grated cheddar so every bite gets flavor
Slice and Top with Chicken
Carefully cut the chicken tenders into your preferred size Arrange them in a single layer across the cheesy casserole
Bake to Perfection
Place the casserole uncovered in the oven Bake for twenty minutes if your chicken is frozen or fifteen minutes if homemade
Make the Gravy
While the casserole bakes warm up your gravy on the stove so it is hot and pourable
Finish and Serve
Drizzle the hot gravy evenly over the casserole Just enough so it clings to the crispy chicken and cheesy potatoes

I always look forward to the cheddar in this dish It melts into the potatoes and creates the best gooey pockets My son loves helping sprinkle the cheese and always asks for extra

Storage Tips

Let any leftovers cool before covering the dish tightly with foil or plastic wrap Refrigerate for up to three days For longer storage freeze portions in airtight containers and thaw overnight before reheating Covered loosely with foil the casserole reheats nicely in a moderate oven or microwave

Ingredient Substitutions

Swap in Monterey Jack or mozzarella for cheddar if you want a milder cheese If corn is not your favorite use green peas instead For the chicken try crispy popcorn chicken or grilled chunks for a lighter version

Serving Suggestions

This hearty casserole is filling on its own A side salad with a zesty vinaigrette helps cut the richness Roasted broccoli or green beans are welcome additions Some families love serving it with extra gravy on the side for dipping
