Cheesy Mashed Potato Casserole is an ultra rich and creamy casserole with 3 types of cheese. Makes a great Thanksgiving side and also goes great with chicken, beef, or pork.
Three Types Of Cheese
There’s 3 types of cheese in this casserole for tons of cheesy flavor: cheddar, mozzarella, and parmesan.
Type of Potatoes
Yukon Gold potatoes are best for this recipe. They are great for mashed potatoes because they have an ultra creamy texture and buttery taste.
A full cup of butter and 1 1/2 cups of half-and-half make for an ultra creamy and rich casserole. With such a rich taste, it’s more of a special occasion casserole than an every day casserole.
This casserole can be prepared up to 8 hours in advance and then baked just before serving.
Panko Crumb Topping
To give the casserole a little texture and more flavor, there’s a buttery Panko crumb topping with a little Parmesan cheese.
