Instant Pot Million Dollar Potato Casserole
Looking for a fast and easy side dish? This is a creamy potato casserole with cream cheese, cheddar, Ricotta (or sour cream, if you prefer) and a Ritz cracker topping. It is so fast because you actually use frozen hashbrowns instead of having to peel and dice potatoes. After they are cooked and stirred together with the other ingredients they are more like mashed potatoes than hash browns. Shhhh, it’s a little secret!
Ingredients/Substitution Ideas
- Frozen hashbrowns–or frozen O’Brien potatoes
- Cream cheese–or a can of cream of chicken or mushroom soup
- Ricotta cheese–or sour cream or cottage cheese
- Dry ranch dressing mix–I like to use Hidden Valley brand and I buy it in the big container from Costco. You can also make your own.
- Cheddar cheese–or Colby, Monterey jack, etc.
- Ritz crackers–or a half cup of panko bread crumbs or crushed cornflakes
- Butter
- Green onion–or chives
How to make potato casserole in the Instant Pot
Because you don’t have to peel and dice potatoes this casserole comes together really quickly! If you’d like you can make this in your slow cooker or oven too. Look at the recipe card below for instructions.
- Quickly pressure cook the frozen hashbrowns in a steamer basket.
- Stir the hashbrowns together with the cheeses and ranch dressing mix. The hashbrowns get creamy almost like mashed potatoes.
- Sprinkle the Ritz crackers on top and drizzle with the melted butter. Brown up the top of the casserole with an air fryer lid.
- Serve and enjoy topped with green onions.
Pro tip: Place the package of cream cheese on top of your Instant Pot lid while the hashbrowns are cooking. It gets warm on the lid and will help soften the cream cheese so that it melts easier.

Equipment
- I used my 6 quart Instant Pot Duo Crisp with Air Fryer Lid*. You can also make this in an 8 quart pot or your 6 quart Crockpot.
- Silicone steamer basket*
What if I don’t have a steamer basket?
If you don’t have a steamer basket you may want to make the slow cooker or oven version of this casserole instead. Both instructions are listed in the recipe card below.
What if I don’t have an air fryer lid?
If you don’t have an air fryer lid you can finish this dish off under your oven’s broiler. Scrape potato mixture into a baking dish. Top with the Ritz and butter and broil for 3-5 minutes.
Does this casserole stay good on the warm setting?
Like most potato dishes in the Instant Pot this casserole is best served right away. However, it will still taste good if you put it on the KEEP WARM setting for up to 2 hours.

Sounds wonderful! Can’t wait to try this one. I might even be a little naughty & toss some crispy bacon in when I mix in the cheeses 😋
