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!

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!

Mashed Potato Casserole with Crispy Chicken

4.92 from 34 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!

  1. In the oven now, super easy, yum!

  2. This is a super tasty dish! HIGHLY recommend pre-slicing the chicken as advised…cut into mine after 22 min cooking and it was still cold 😪 

  3. I have never made mashed potatoes this way, but my stepson commented that they were really good. My whole family enjoyed this recipe and wanted it added to our regular rotation! Thank you!

    • Hey Amanda! That is SO great to hear, I’m so glad! And thank you so much for taking the time to leave a review too, I really appreciate it!! -Stephanie

  4. Hi Stephanie! This looks awesome. Have you ever made and frozen this to eat later?

  5. Made this for dinner tonight. Yummy comfort food on a January night. I divided the recipe for, part for my small family of 4 (two small kids and 2 adults) and part for a neighbor who’s wife is ill. I baked them in small round Pyrex dishes and they took more than 20 minutes but otherwise turned out great. Next time I’ll peel the potatoes ahead of time to save time. Thanks for a great recipe.

  6. This was an awesome dish.

  7. My family of 5 ages 3 to 38, absolutely loved this. Said it’s probably their favorite meal now. 

  8. Just to be clear, you don’t have to cook the frozen chicken fingers before adding them to the casserole ?

  9. My husband use to order this from KFC and I wondered how did he eat that! Well I made this and sampled it. It is delicious and he loves it.

    • Hi Jeanne! I’m so happy that you guys enjoyed this recipe! It definitely reminds me of KFC, but even better! Thank you for taking the time to comment and rate! 🙌🏻 -Stephanie

  10. I made this with my own breaded boneless pieces, about 1 inch pieces.. not a big fan of frozen chicken, I also used canned mushroom gravy, it was absolutely wonderful…. thanks for sharing….
