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.


  • 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.
  • Brown Gravy- My homemade brown gravy is SO easy and takes 10 minutes! (But a packet works too.)

Make it from Scratch!


How to Make the Best Mashed Potatoes

Everything from the type of potato you use, how you boil the potatoes, and even to how you mash them up is important. Be sure to check out my mashed potato recipe for all the info!

Vegetable Variations:

  • Frozen peas, carrots, corn, and green beans make excellent vegetable options in this casserole!

Mashed Potato Casserole with Crispy Chicken

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!


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


  • 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!

  1. Great casserole!  Hubby and kids loved it. Definitely going into the rotation. I cheated and used Tyson chicken strips and made 3 envelopes gravy. I also doubled the corn and cheese.  

  2. Just a note that the 20 min baking time for frozen chicken tenders is if they are pre-cooked. I used uncooked frozen chicken tenders and needed to bake it longer.

  3. We have made this several times and different ways every time! Frozen chicken, homemade chicken, packet gravy, KFC gravy, homemade potatoes, premade Bob Evans potatoes, it’s DELICIOUS every time!!!!!!!! 

    • I’m so happy that you have enjoyed it no matter how you’ve made it Britt!! Wahooo!! Thank you so much for taking the time to leave a review, I really appreciate it! 🙂 -Stephanie

  4. Should I spray my pan first?

  5. Delicious! Added sauteed onions and baby Bella’s.

  6. We love this recipe. Thank you for sharing. So easy and delicious. 

    • Hi Melissa! I am so happy to hear that you love this casserole, it’s always a hit in our house too! Thank you so much for taking the time to leave a review, I really appreciate it! -Stephanie

  7. It was excellent. I made my own chicken nuggets, they were crispy as noted! I made my own gravy and it was delicious as well! 

  8. This may sound too easy but believe me it’s the bomb.

  9. My husband asks me to make this multiple times a week. We both love it. It’s so comforting and delicious.
