Plus, I’ve added a make ahead note so this recipe can easily make an appearance on your holiday table this year. And since it calls for unpeeled potatoes, you can count on that extra nutritional punch that you wouldn’t get otherwise. Enjoy!
Cheesy Mashed Potato Casserole
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.
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.
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.
We recommend organic ingredients when feasible.
