I mix up condensed cream of cheddar soup, sour cream, and cheese with hash browns to get my bomb hashbrown casserole. My secret is in the spice mix that no other recipe has. No lies but it’s better than Cracker Barrel’s!

This recipe is legit as easy as can be. Here are a few tips I discovered while testing to ensure your casserole turns out perfectly.
- Thaw the hashbrowns. Let them thaw in a colander in the sink, or if you’re in a rush, toss them in a big bowl and hit the microwave’s defrost setting for about 3-4 minutes, stirring halfway.
- Shred your own cheese. Pre-shredded cheese has anti-caking agents that mess with the melt.
- Keep that top from burning. If the cheese is getting too golden before the cook time’s up, tent it with foil and let it finish baking.

Notes
Can I freeze hashbrown breakfast casserole?
Absolutely! Wrap it up tight in plastic wrap and foil or store it in a freezer-safe container. It’ll keep for about 2 months. Ingredient Swaps and Information-
- Hashbrowns: I use frozen shredded hashbrowns because they’re quick and easy, but if you wanna go homemade, they’re simple to make.
-
- Cream of Cheddar Soup: Cream of chicken or cream of mushroom will work too.
-
- Sour Cream: You can swap it for full-fat plain Greek yogurt if that’s what’s in your fridge.
-
- Butter: Try a good-quality olive oil instead.
-
- Colby Jack Cheese: Cheddar, mozzarella, gouda also work here.

Pop it under the broiler for a minute or two at the end. Keep a close eye on it tho!
Yep! You can mix everything up the night before, cover it, and chill in the fridge. Just let it come to room temp for about 30 minutes before baking so it cooks evenly.
Hashbrowns can hold a lot of moisture, especially if they weren’t fully thawed and drained. Next time, make sure to pat them dry with paper towels before mixing everything up.
A perfect combination of crispy, tender, and creamy!! I’ve made this time and again for weekend breakfasts for my family and brunches with friends! This casserole will stay on heavy rotation in my kitchen! Thank you, Jocelyn!
Thanks so much, doll!
