Easy Hashbrown Casserole – creamy and cheesy potato dish made with just a few ingredients! No canned cream of soup needed!
Easy Hashbrown Casserole makes for a perfect side dish for holiday dinner, weekend brunches or when you simply crave comfort food. I am excited to share my recipe that does not require a can of condensed cream of soup yet still is creamy, cheesy and delicious! It’s pure comfort food! So good, you will reach for seconds. Made with a super easy substitute for cream of soup, sour cream and frozen hash browns, this casserole is super easy to make and can easily be prepared ahead of time.
- frozen hashbrowns
- yellow onion
- half and half
- salt and pepper
- dried dill
- sour cream
- cheddar and Monterey Jack cheese
How to make it?
- Prepare the condensed cream of soup substitute.
- Mix hashbrowns (thawed) with the creamy mixture, sour cream, salt and pepper. It should be thick and creamy.
- Spread the mixture in a buttered casserole dish, top with cheddar and Monterey Jack cheese.
- Bake until bubbly and the cheese is melted.
Condensed cream of soup substitute from scratch:
Most recipes for hash brown casserole call for a can of condensed cream of chicken, celery or cheddar soup. Since I don’t use these in my kitchen, I found a way to make a creamy mixture with half and half and cornstarch as a perfect substitute. It takes only 5 to 7 minutes to cook it in a saucepan.
- First, saute garlic and onion in butter.
- Add half and half whisked with cornstarch, salt and pepper. I also add dill because I just love dill in potato dishes.
- Cook, stirring constantly, until thick and creamy.
- At this point, you can place cooled mixture in a jar, cover and refrigerate until you are ready to use it.
Yes, you can easily freeze this casserole. Prepare and freeze. Bring to room temperature before baking.
To reheat any leftovers, simply place the dish in the oven preheated to 350 degrees F and bake for 20 minutes or until heated through.
