Crockpot Hashbrown Casserole Without Sour Cream (Easy + Cheesy)

Looking for a creamy, cheesy potato side dish that doesn’t use sour cream? This crockpot hashbrown casserole without sour cream is the ultimate comfort food. With tender shredded potatoes, melty cheddar, and savory onions, it’s perfect for holiday breakfasts, potlucks, or weeknight dinners.

I’ve always had a soft spot for hashbrown casseroles. They’re the kind of cozy, cheesy comfort food that shows up at every holiday table and family brunch. But as much as I love the classic versions, I often find myself craving something a little lighter — especially casseroles that are just as creamy without the sour cream.

Over the years, I’ve tested this recipe more times than I can count, trying different swaps and tweaks. My personal favorite version uses my homemade vegan cream of mushroom soup as the base. It gives the casserole a rich, savory flavor without feeling heavy, and it keeps the texture wonderfully creamy. That said, the other sour cream–free options I’ve shared here — from Greek yogurt to cream cheese or even dairy-free alternatives — are all delicious in their own right and definitely worth trying.

Pro Tip: If you’re making this for a crowd, try two different versions side by side — you’ll be surprised at how quickly both dishes disappear

Ingredients for Hashbrown Casserole Without Sour Cream

This recipe uses basic ingredients you likely already have. We’re talking simple kitchen stables that create a delicious casserole:

• Butter or vegan butter
• Onion (diced)
• Garlic (fresh or powder)
• Shredded hash brown potatoes (frozen or refrigerated)
• Shredded cheddar cheese (or vegan cheese / nutritional yeast)
• Condensed cream of mushroom soup (or vegan alternative / white sauce) I like to use my vegan Cream of mushroom soup
• Water
• Salt + pepper

Substitutions for Sour Cream

In my easy recipe I like to use plant based cream of mushroom soup which is naturally free of sour cream. However, if you’re looking for more sour cream free options, I’ve got you covered. You can try any one of these and still make a delicious hash brown casserole. Instead of sour cream, try one of these tested swaps:

• Greek yogurt (1:1) – tangy, creamy, healthier.
• Cream cheese + splash of milk – extra rich and smooth.
• Cottage cheese (blended) – light but creamy.
• Dairy-free cream soup or vegan cream cheese – for vegan or lactose-free diets.
• Homemade white sauce – for a no-soup version.

How to make crockpot hashbrown casserole without sour cream recipe:

How to Make Crockpot Hashbrown Casserole Without Sour Cream:

• Prepare your ingredients: Gather all your ingredients and make sure your slow cooker is ready. Lightly coat the inside of a 5-quart slow cooker with cooking spray to prevent sticking.
• Cook the onions and garlic: In a medium-sized skillet (about 8 inches), melt the butter over medium heat. Add the diced onions and chopped garlic, stirring frequently. Sauté for 2-3 minutes until the onions become translucent and soft. Be careful not to burn the garlic, as it can turn bitter.
• Combine ingredients: In a large mixing bowl, combine the sautéed onion and garlic mixture with the remaining ingredients—hashbrowns, cheese, cream of mushroom soup, water, salt, and pepper. Stir everything together until it’s evenly mixed and well combined.
• Transfer to slow cooker: Pour the mixture into your prepared slow cooker. Smooth it out so the casserole cooks evenly.
• Cook: Cover the slow cooker with the lid and cook on the Low heat setting for 3 hours. After 3 hours, give it a stir to ensure even cooking. Cover again and continue to cook on Low for an additional 2-3 hours, or until the center reaches at least 165°F and the edges are bubbling.
• Serve: Once cooked through, give the casserole a final stir before serving. Enjoy the rich, cheesy flavors with your favorite sides!

Instructions for Oven-Baked Hash Brown Casserole without sour cream:

• Preheat your oven to 350°F (175°C).
• Prepare the Baking Dish: Grease a 9×13-inch baking dish with cooking spray or lightly coat it with butter or oil.
• Sauté the Onion and Garlic: In a medium skillet, melt the butter over medium heat. Add the diced onion and chopped garlic (or garlic powder) and sauté for 2-3 minutes until soft and translucent.
• Combine the Ingredients: In a large mixing bowl, combine the sautéed onion and garlic, shredded hash browns, shredded cheddar cheese (or vegan option), condensed cream of mushroom soup (or vegan alternative), water, salt, and pepper. Stir everything until well combined.
• Transfer to Baking Dish: Pour the mixture into the greased baking dish, spreading it out evenly.
• Bake: Cover the dish with aluminum foil and bake in the preheated oven for about 45 minutes. Then, remove the foil and bake uncovered for an additional 15-20 minutes or until the top is golden brown, the edges are bubbly, and the casserole is heated through (center should reach at least 165°F/74°C).
• Serve: Remove from the oven and let it cool for a few minutes before serving. This will allow it to set a bit and make it easier to slice and serve.
• Enjoy your oven-baked hash brown casserole as a hearty, cheesy side dish or main course!

Notes

1 serving is approximately 235kcal

Extra tip: If you like a crispy top, transfer the finished casserole to a broiler-safe dish and broil for 2-3 minutes until the cheese turns golden and bubbly.

Tip 1:

For an even more convenient way to make cheesy hash browns in the slow cooker, opt for refrigerated pre-shredded hash brown potatoes. They eliminate the hassle of grating your own, and unlike freshly grated potatoes, they won’t brown or oxidize while you’re prepping the other ingredients.

Tip 2:

Sautéing the onions and garlic before adding them to the slow cooker adds a deep, rich flavor to the dish. These “aromatics” don’t just add taste; their irresistible aroma will have everyone eagerly anticipating the meal.

Tip 3:

Remember to stir your cheesy hash brown casserole halfway through the cooking process. This will help prevent the edges from overcooking or burning, ensuring the dish stays creamy and evenly cooked.

Tip 4:

If you’re looking for a soup-free version, you can replace the condensed soup with a thick, homemade white gravy. It will still deliver a creamy, rich consistency without the need for canned soup.

Tip 5:

For an extra layer of flavor, swap out the cream of mushroom soup for cream of poblano soup. This will add a subtle hint of smokiness and spice to the dish.
