Love hashbrowns? Turn them into a full meal with my Slow Cooker Breakfast Casserole recipe.

This recipe is a favorite simply because it has few ingredients. Beyond the seasonings, you’ll only need frozen shredded hashbrowns, shredded cheese, and sour cream. The prep time is quick, and the quick cook time gives you the option to get some stuff done before serving.
It’s also a big hit and a family favorite because it’s super versatile. Leave it as is or go for some additions like diced jalapenos, cooked and crumbled sausage (or beef), and extra varieties of cheese. If you’re looking for a quick and easy appetizer, meal, or snack to serve a crowd at a pot luck, this recipe is one to try.

Step Three – Add the cheesy hash brown mixture to the sprayed slow cooker.

Step Four – Cover and cook on HIGH for 3 hours and 20 minutes.
Step Five – Add the remaining cheese (2 cups).
Step Six – Put the lid back on until the cheese melts. Serve and enjoy!

Serving Suggestions
Here are my favorite ways to serve this potato dish:
- This casserole is great on it’s own, but also pairs well with a variety of toppings. Think diced ham, colby jack cheese, extra shredded cheddar cheese, diced onions, or green onions.
- Main dishes that go great with this are pork chops and onions, BBQ Crockpot back ribs, and Crockpot Ham, we also love to make air fryer fried chicken!
- You can also serve it as a side dish with scrambled eggs, sausage, and bacon for breakfast.
- The leftovers also make a great meal and can be turned into something new with a few extra sides and toppings (think baked potato toppings).

Recipe FAQs and Variations
Place any remaining hash brown casserole in an airtight container and keep in the fridge for up to 4 days. Reheat in the microwave or oven until warmed throughout.
Greek yogurt tends to turn into water when put into hot dishes. I suggest using sour cream as the recipe calls for.
Yes, but I would not cook it longer than 4-5 hours on LOW.
Yes, and you’ll want to be generous with it. You may also try a slow cooker liner to prevent sticking.
You can add cream of chicken soup, mushroom soup, use frozen diced potatoes, or add extra cheese to make cheesy potatoes.

- Are you tempted to use Greek yogurt instead of sour cream? Don’t, for greek yogurt tends to turn watery when added to hot dishes.

I made this using only 16 ounces of sour cream (all I had on hand). I added 2 cans cream of chicken soup and 1/2 cup water. I also added diced cooked onion. Added the cheese as instructed. I proceeded with cook time and added cheese on top at the end. Absolutely fantastic!
How many would this feed as a side dish? Do you think I could double it? I’m having a party for 60 people.
Hi! this recipe serves 8 as a side dish. I’m unsure how this would turn out doubled in the slow cooker, I don’t know if the potatoes would cook in the center before burning around the edges.
Yes I’ve tripled it before lol
Stir often
If you double this recipe, what how long do you cook it for? And on high or low?
Could you use frozen diced potatoes instead?
I’m unsure without testing it first for timing and flavor. I apologize.
Yes
I add a stick of butter to mine.
Can you freeze this after it’s cooked?
Potaotes don’t freeze well, I apologize.
I thought so; too bad!
I thought so; too bad!
They started out frozen
Would this work on low heat instead of high or do you think it might burn cooking longer?
It’s hard to say without testing. Sorry! It may burn on the edges.
Loved by my family!!
I will tre this soon
This recipe turned out great! The fact that it did not have cream of chicken soup was a plus for one our family members that is vegetarian. This will be my go to for party potatoes.
You give all the nutritional information for this recipe (which is great), but you don’t state the serving size. Based off 8 people… but how much did those 8 people get? 1 cup? 2 cups?
I’m sorry this website can not provide that information for the recipes at this time. I apologize.
