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.
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:

Make-Ahead Method:
Prep Work:
Prepare homemade potatoes, chicken tenders, and brown gravy. Store each in a separate airtight container for 1-2 days ahead. Grate the cheese ahead of time and keep it in a small storage bag in the fridge.
When Ready to Bake:
Heat up the potatoes. (On stove top or in the microwave) Top with frozen corn, cheese, and chicken. Bake for 15 minutes. Reheat the gravy in the microwave or stove top. Drizzle the gravy over the casserole and serve!
Storing Leftovers
Leftovers can be stored in an airtight container in the fridge and are best if used within 3 days. You can reheat in the microwave or in an oven at 350°. You can also freeze leftovers in an airtight container, it’s best if used within 3 months.
