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!
- Homemade Mashed Potatoes
- Fried Chicken Tenders
- Easy Brown Gravy

Mashed Potato Casserole with Crispy Chicken
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!

this is a fantastic stoner meal 😀
Easy and fast. I used instant mashed potatoes and drained can corn, I as in a real hurry to get dinner on the table.
Nice Leanette! So happy you enjoyed it!!! 🙂
This sounds really good, and because I live alone and cook only for myself, it’ll give me leftovers for a few meals besides the initial one. Because of severe allergies to many foods, I’d leave the gravy off the dish, but since I prefer butter to any other topping, I’m sure I can “tough it out” with that :-D.
Making this again tonight for the second time. SO good and the whole family loved it. Comfort food at its best 🙂
Excellent! That’s so great Nicole, thank you so much for taking the time to rate and comment!! I really appreciate it! -Stephanie
Are the chicken tenders from frozen to the top of potatoes or thaw first??
Hi Brenda, they’re still frozen, I like to let them sit out for 5 minutes so I can cut them into smaller pieces though! Enjoy! -Stephanie
This casserole recipe is the bomb. So delicious. Thanks
Hi Rusty! I’m so so happy that you like it! Thank you so much for taking the time to leave a comment and a rating!!! Have a great weekend! -Stephanie
I am not one to usually leave a review but this casserole was simple and very flavorful. Everyone went for seconds, a big hit for sure. Mine had a couple slight variations. I added Fried onion pieces on top with the chicken and substituted country gravy for the brown gravy. This is definitely and new family favorite! Thank you.
Hey Lyndsey! I am sooo happy that you took the time to leave a review here! It totally made my day, SO glad that you all enjoyed this casserole! Country gravy sounds amazing and I love crispy fried onions, I’m totally adding that next time! 🙂 Thank you for sharing! Have a wonderful day! -Stephanie
Good and easy! Makes a lot! But, needed more corn, chicken, and gravy for the amount of potatoes. The potatoes really overpowered the other ingredients in the casserole. Thank you for the recipe and will be saving to make again!
Hi Maddison! Thank you for your comment, I appreciate it! I updated the quantity of potatoes from 6 to 5 to try to mitigate this, glad you’ll be making it again! -Stephanie
Looks yummy! Are the Tyson chicken strips supposed to be cooked or just thawed when putting together this casserole?
Hi Kristina! Just thawed is fine! 🙂
Sounds really good, will definitely try, thanks
Excellent Shirley! Can’t wait for you to make it!
Ah… just like KFC’s “Sadness” Bowl (if you don’t get that reference Google comedian Patton Oswalt’s skit about it – it’s hilarious. 😀
Personally, if you’re going to take the shortcut of using frozen chicken strips (which I understand this post was sponsored by Tyson, so they had to be in there), why not make it super-easy on yourself and just use instant mashed potatoes too?
And, forget messing with a brown gravy packet? Just buy a jar (or can) of gravy. This recipe would then take zero cooking skills to make.
Just a thought!
Hey Kim! No I totally get what you’re saying! I just wanted to have “more” i information instead of less so I fcured if someone does want to make their own mashed potatoes then they have all the info! I personally (really) dislike instant mashed potatoes do I’d never use those but that’s a personal preference! Same with gravy, I am partial to the pockets but if someone wants to use a jar instead, that’s easy enough! Totally easy to customize. I’ll have to check out that comedy clip you mentioned! Have a great rest of your weekend! -Stephanie
Can you use boneless chicken breast? I don’t usually have chicken strips on hand.
You could! It won’t be quite the same and you could buy some Tyson Chciken Strips and keep them in the freezer for whenever you want to make this, but if you use boneless I would sear strips of chicken in a skillet and then dice them and top the casserole with it! 🙌🏻 -ENJOY! It’s sooo good!! -Stephanie
