Cheesy Mashed Potato Casserole
You are going to love this cheesy mashed potato casserole which has a layer of warm toasted cheese on top - so yum! Plus, I've added a make ahead note.
Ingredients
Instructions
- Set a pot of water over high heat to boil. Scrub the outside of the potatoes with water and a bristled brush (no need to peel!). Dice into 1 to 2 inch pieces. Add the potato pieces to the water and cook until tender when pierced with a fork, about 15 to 20 minutes.
- Drain the water and puree the potatoes with an electric mixer or hand masher. Mix in the butter, milk, salt, and pepper until thoroughly combined and smooth being careful not to overmix.
- Turn the oven broiler to high. Transfer the potatoes to a baking dish and top with an even layer of the grated cheese. Place it right under the broiler until the cheese is melted and just begins to brown (be sure to watch it closely!), about 5 to 8 minutes. Serve warm.
Recipe Notes
Make Ahead: Complete steps 1 and 2 in advance and refrigerate the mashed potatoes overnight. Then prior to step 3, heat the potatoes in the oven at 350 degrees F for 20 to 30 minutes.

Can you substitute Almond or Coconut milk? We are lactose free…
Hi there. You can.
Love this recipe so easy and yummy!
I live in the middle of nowhere and am curious what brands of cheese don’t use dye?? I haven’t been able to find cheese in my town that is dye free yet. Thank you!
Hi Rebekah. Just know that cheddar should be white not yellow/orange. :)
Hello! I love your website, have bought your cookbook, etc… Thank you for it all! This recipe was a huge hit at my house. Question – is this gluten-free? I’m making a meal for a gluten-free family and wanted to include this. Thanks in advance.
Yep, no gluten in this recipe.
My family is obsessed with mashed potatoes, which drives me crazy because of the hassle. Would this freeze?
Hi Rebecca. Yes, you can freeze this.
These were fantastic! Even my kids who aren’t big fans of any mashed potato gobbled them up! Easy and tasty!
We ended up making a double batch in a 13×9 dish to serve 10 people for Thanksgiving. A real hit, very easy, and something I felt good about serving.
