This Crockpot Cheesy Potato Casserole is warm, creamy, and downright cheesy! Made with tender potatoes, a rich cheese sauce, and spices, it’s a comforting dish everyone loves.
Honestly, who can resist something this cheesy? I always lose track of servings because it disappears so fast! Just toss everything in the crockpot and let the magic happen!
Key Ingredients & Substitutions
Frozen Diced Hashbrowns: These are super convenient and cook well in the crockpot. If you don’t have them, you can use fresh potatoes, but you’ll need to dice them and might want to parboil them slightly to ensure they cook through.
Cream of Chicken Soup: This gives the casserole a creamy base. If you’re vegetarian or want a lighter version, try using cream of mushroom soup or a homemade creamy sauce with broth and flour.
Sour Cream: Adds tanginess and creaminess. Greek yogurt makes a great substitute if you want to cut calories but maintain the creaminess!
Cheddar Cheese: Sharp cheddar is my go-to for more flavor. However, feel free to mix in other cheeses like Monterey Jack or mozzarella for a different taste!
Chopped Onion: This adds extra flavor. If you’re not a fan of raw onions, try using onion powder instead or sauté some fresh onions before adding them.
How Do I Get the Perfect Cheese Layer at the End?
One of the highlights of this casserole is the gooey cheese on top. For a flawless melty finish, sprinkle the remaining cheese about 15 minutes before you serve it. This way, it has just enough time to melt without overcooking. Make sure your crockpot is still on, and keep the lid on to create steam for melting!
- Layer the cheese just before serving.
- Keep the lid closed to help it melt evenly.
- Consider adding a few extra minutes to ensure everything is bubbly and perfect!

Step-by-Step Instructions:
1. Prepare the Crockpot:
Start by spraying the inside of your crockpot with nonstick cooking spray. This helps prevent sticking and makes cleanup easier!
2. Mix the Cheesy Sauce:
In a large bowl, mix together the cream of chicken soup, sour cream, 1 1/2 cups of the shredded cheddar cheese, melted butter, garlic powder, salt, and black pepper. Stir until everything is well combined and creamy.
3. Add the Potatoes and Onion:
Gently fold the thawed diced potatoes and chopped onion into the cheese mixture. Make sure every piece of potato is coated with that cheesy goodness!
4. Cook in the Crockpot:
Transfer the potato mixture into the prepared crockpot and spread it out evenly. Cover the crockpot lid and cook on LOW for about 4 to 5 hours. You’ll know it’s ready when the potatoes are tender when pierced with a fork.
5. Top with Cheese:
About 15 minutes before you’re ready to serve, sprinkle the remaining 1/2 cup of shredded cheddar cheese on top of the casserole. Cover it again and let it cook for those last few minutes until the cheese is perfectly melted.
6. Garnish and Serve:
When ready to enjoy, sprinkle some freshly chopped parsley or chives on top for a pop of color and flavor. Serve warm and dig into this creamy, cheesy casserole—your taste buds will thank you!
This Crockpot Cheesy Potato Casserole is perfect for parties, potlucks, or a cozy family dinner. It’s easy to make and a guaranteed hit!

Can I Use Fresh Potatoes Instead of Frozen Hashbrowns?
Yes, you can! If you prefer fresh potatoes, make sure to peel and dice them into small pieces. You may want to parboil them for about 10-15 minutes before adding them to the casserole to ensure they cook through properly in the crockpot.
What Can I Substitute for Sour Cream?
If you want a healthier option, Greek yogurt is a great substitute for sour cream. It will still give you that creamy texture with a beneficial tang. You can also use cottage cheese for a unique twist!
How Long Are Leftovers Good For?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Make sure to reheat thoroughly on the stove or in the microwave before serving again.
Can I Make This Casserole Vegetarian?
Absolutely! To make this dish vegetarian, simply replace the cream of chicken soup with cream of mushroom soup or a homemade vegetable cream sauce. It’s just as delicious without the meat!
