It is that good.

How to Make Mashed Potato Casserole with Hash Browns

This potato casserole is super easy to make. Starts with making a couple of packets of instant mashed potatoes. Next, mix in frozen shredded hash browns, butter, frozen spinach, chopped artichokes, softened cream cheese, Monterey Jack cheese, sour cream, and Italian dressing mix. Transfer the potato mixture to a deep-dish 9×13-inch pan. Top the casserole with some French fried onions and bake.

Tips for Making Instant Mashed Potato Casserole

  • Can substitute 4 cups prepared mashed potatoes for instant mashed potatoes. Our Roasted Garlic Mashed Potatoes work GREAT in this dish!
  • I did not thaw the frozen shredded hash browns before adding them to the casserole.
  • Can substitute fresh spinach for frozen spinach.
  • Do NOT make the Italian dressing. You are going to use the mix dry. It is to season the casserole.
  • If you need a gluten-free casserole, you can leave off the fried onions or substitute crushed pork rinds.
  • I used Monterey Jack cheese, but any cheese you like will work fine. Cheddar, Pepper Jack, gruyere, or Gouda would be yummy.
  • Turn this into a main dish by adding some cooked chopped chicken.
  • Can make the casserole in advance and refrigerate or freeze for later.
  • To bake casserole after freezing, thaw completely and bake as directed below.
  • To reheat casserole after freezing, partially thaw. Cover with aluminum foil and bake at 350ºF for 30 to 40 minutes.
