Mashed Potato Casserole

Sunday meal prep has been my jam lately, and I’m so thrilled to be growing my collection of casseroles that are easy to throw together and can made ahead of time.

Not to mention, if you find yourself with some leftover mashed potatoes, then this dinner is a no-brainer.

Ingredients

  • Mashed Potatoes- My homemade recipe is portioned perfectly for this recipe.
  • Corn– Frozen or drained from a can
  • Cheddar Cheese– Shredded from a block at home for best results
  • Chicken Tenders- It’s GREAT with my homemade chicken tenders but you can also use frozen. My popcorn chicken is perfect as well!
  • Brown Gravy- My homemade brown gravy is SO easy and takes 10 minutes! (But a packet works too.)

Make it from Scratch!

Mashed Potato Casserole with Crispy Chicken

4.87 from 37 ratings
This mouth-watering mashed potato casserole is topped with Corn, Cheddar Cheese, Tyson® Chicken Strips, and a drizzle of brown gravy! It’s easy to make ahead of time and bake later for a quick family dinner!

Ingredients

For Casserole:

  • 5-6 cups mashed potatoes, my homemade version is portioned for this recipe
  • 1 cup corn
  • 1 cup cheddar cheese, freshly grated
  • 8 Chicken Tenders, I prefer my homemade recipe but frozen may be used
  • Brown Gravy, you can also use a packet

Instructions

  • Preheat the oven to 400 degrees Fahrenheit.
  • If using frozen chicken tenders, let them sit at room temp for about 5 minutes if you prefer to slice them first, this allows them to soften.
  • Spread the potatoes on the bottom of a 9 x 13 casserole dish.
  • Note: If your mashed potatoes are cold, warm them first.
  • Top with corn and cheese.
  • Carefully slice the chicken strips into pieces of desired size and top the casserole dish with them.
  • Bake uncovered for 20 minutes if using frozen chicken tenders and 15 minutes for homemade.
  • Prepare the gravy on the stove top while the casserole finishes baking.
  • Drizzle desired amount of gravy over the casserole dish and serve!

Notes

My homemade Popcorn Chicken is great in this recipe as well!
