There’s something about walking into a house that smells like melted cheese and warm potatoes simmering all day. Slow Cooker Cheesy Ranch Potato Soup is that kind of magiccreamy, tangy from ranch seasoning, and loaded with tender chunks of potato that practically melt on your spoon. It’s the soup you crave on a drizzly Tuesday when dinner needs to basically cook itself.
I started making this back in 2019 when I was testing comfort soups for the blog, and I must’ve tried twelve different potato bases before landing on this one. The ranch powder does something unexpectedit brightens the cream without making things heavy, and when you stir in sharp cheddar at the end, it gets this gorgeous, glossy swirl. After ten years writing about food, I can tell you: the best recipes are the ones you don’t have to babysit.

Easy Slow Cooker Cheesy Ranch Potato Soup Recipe
This Slow Cooker Cheesy Ranch Potato Soup is a creamy, flavorful dish loaded with tender potatoes and the delicious taste of ranch seasoning. Made effortlessly in your slow cooker, it’s topped off with crispy bacon, sharp cheddar cheese, and fresh green onions for a comforting meal that’s perfect for any day.
Place the potatoes, diced onion, diced celery, and chicken broth into the slow cooker. Set it on low and allow it to cook for 5 to 6 hours, or alternatively, use the high setting and cook for 3 to 4 hours until the potatoes become soft.
Once the potatoes are tender, lightly mash them directly in the slow cooker. Then add the flour, ranch seasoning, 2 cups of shredded cheddar cheese, sour cream, salt, pepper, and half and half. Stir everything thoroughly to combine.
Cover the slow cooker again and let the soup cook for another 30 minutes to allow it to thicken and for the flavors to meld.
If you’d like a chunkier texture, serve the soup as is with lightly mashed potatoes. For a smoother consistency, blend the soup gently with an immersion blender until creamy.
To finish, ladle the soup into bowls and garnish with the reserved crumbled bacon, diced green onions, and the remaining shredded cheese before serving.
Notes
For a richer soup, you can substitute half and half with heavy cream. Leftovers keep well refrigerated for up to 3 days and taste great reheated.

Pantry-friendly ingredients: You probably have most of this already, and the rest you can grab in one quick grocery run.
Key Ingredients You’ll Need
Here’s what makes this soup work. I always keep russet potatoes on handthey break down just enough to thicken the broth without turning gummy. The ranch seasoning is your secret weapon; it brightens everything without making the soup taste like salad dressing. And half and half? That’s what gives you creaminess without the weight of straight heavy cream.
Pro Tip: Use block cheddar and shred it yourself if you can. Pre-shredded cheese has anti-caking powder that can make your soup grainy instead of silky.

How to Make It (Step-by-Step)
Start by peeling and cubing your russet potatoes into bite-sized piecesabout an inch works well. Toss them into the slow cooker along with diced onion, celery, and chicken broth. Cover and cook on low for 5 to 6 hours, or high for 3 to 4 hours, until the potatoes are fork-tender and starting to break apart at the edges.
Once they’re soft, give them a gentle mash right in the potjust enough to release some starch and thicken the soup. Stir in the flour, ranch seasoning, 2 cups of shredded cheddar, sour cream, salt, pepper, and half and half. Mix everything until it’s smooth and creamy, then cover again and let it cook for another 30 minutes so the flavors marry and the cheese melts completely.
When you’re ready to serve, decide on your texture: leave it chunky for a rustic feel, or use an immersion blender to puree it into velvety smoothness. Ladle into bowls and pile on the cooked, crumbled bacon, green onions, and remaining cheddar cheese.
Tips for the Best Results
Don’t skip the mashing step: Even if you’re blending it later, breaking up some of the potatoes helps thicken the broth naturally without adding extra flour.
Add dairy at the end: Stirring in the half and half and sour cream during the last 30 minutes prevents curdling and keeps everything silky.
Taste before serving: Ranch seasoning can vary in saltiness, so adjust your salt and pepper right before ladling it out.
Make it heartier: If you want more protein, stir in shredded rotisserie chicken along with the cheese.
How to Serve and Store
Serve this Slow Cooker Cheesy Ranch Potato Soup in wide, shallow bowls so you can really pile on the toppings. It pairs beautifully with crusty bread, buttered sourdough toast, or even saltine crackers for a nostalgic touch. I like to set out extra bacon, cheese, and green onions so everyone can customize their bowl.
Storage Method
How Long It Lasts
Reheating Tip
Refrigerator (airtight container)
3–4 days
Reheat gently on stovetop, add splash of broth if thickened
Freezer (without dairy)
Up to 3 months
Thaw overnight, then stir in fresh half and half when reheating
Toppings (stored separately)

Add fresh bacon and cheese right before serving
Note: Dairy-based soups can separate slightly when frozen, so I usually freeze the base before adding the half and half and sour cream, then stir those in fresh when I reheat.

FAQs (Slow Cooker Cheesy Ranch Potato Soup)
What type of potatoes work best for this soup?
Russet potatoes are ideal because they break down slightly during cooking, naturally thickening the soup. Yukon Gold potatoes also work well and hold their shape better if you prefer chunkier pieces. Avoid waxy red potatoes as they won’t create the creamy texture this recipe needs.
Can I make this recipe ahead of time?
Yes, you can prepare this dish up to 2 days ahead and store it in the refrigerator. The flavors actually improve overnight. Reheat gently on the stovetop, adding a splash of milk or broth if it gets too thick. Avoid freezing as dairy-based soups can separate when thawed.
How do I prevent the soup from curdling?
Keep your slow cooker on low heat and add dairy ingredients during the last 30 minutes of cooking. Never boil the soup once cream or cheese is added. If using cream cheese, let it come to room temperature first and whisk it smooth before stirring into the hot soup.
What cheese gives the best flavor and melting?
Sharp cheddar cheese provides the best balance of flavor and smooth melting. Freshly shredded cheese melts better than pre-shredded varieties. For extra richness, combine cheddar with a small amount of cream cheese or Monterey Jack for the perfect creamy texture.
How long should I cook this in the slow cooker?
Cook on low for 6-7 hours or high for 3-4 hours until potatoes are fork-tender. Add cheese and dairy ingredients only in the final 30 minutes to prevent separation. The longer cooking time on low heat develops better flavors and ensures perfectly tender potatoes.
