Easy Crockpot Potato Soup
This creamy, cheesy potato soup is simple to prepare in a slow cooker and perfect for cozy weeknight dinners.
I make this slow-cooker potato soup whenever I want something warm, low-effort, and reliably comforting — it’s the kind of meal that turns a busy weeknight into a cozy family dinner. The hands-off crockpot method lets the potatoes and onion soften into a rich base while you get other things done; if you enjoy slow-cooker dinners, try pairing it with a hearty companion like this easy crockpot chicken and gravy for a full comfort-food spread.
Why you’ll love this dish
This recipe is simple, forgiving, and excellent for busy cooks. It uses inexpensive pantry staples, takes minimal hands-on time, and finishes with a creamy, cheesy comfort that appeals to kids and adults alike. Make it for a chilly weeknight, a casual potluck, or when you want a low-effort meal that still feels special.
Beyond comfort, this soup is flexible: use vegetable broth to keep it meat-free, swap cheeses depending on what’s on hand, or turn leftovers into a loaded baked-potato topping. If you’re exploring other soup ideas, check my roundup of soup recipes for more inspiration.
Step-by-step overview
This crockpot potato soup is straightforward: add diced potatoes and onion to the slow cooker with broth, cook low and slow until tender, mash some of the potatoes right in the pot for body, then stir in cream and cheese. The entire process is mostly unattended — perfect for days when you can’t babysit the stove.
- Prep: Peel and dice potatoes, chop an onion.
- Slow-cook: Combine with broth in the crockpot and cook until tender.
- Finish: Mash part of the potatoes, add cream and cheese, season, and garnish.
What you’ll need
- 4 large potatoes, peeled and diced (about 2–2.5 lbs)
- 1 onion, chopped
- 3 cups vegetable or chicken broth (use low-sodium if watching salt)
- 1 cup heavy cream
- 1 cup shredded cheese (cheddar is classic; try sharp for more bite)
- Salt and pepper to taste
- Green onions or chives for garnish
Substitution notes:
- For a lighter soup, use half-and-half or whole milk instead of heavy cream (see Tips below).
- Swap the cheese: Gruyère gives a nutty depth; pepper jack adds heat.
- For vegan/plant-based: use vegetable broth, a non-dairy cream (like cashew cream), and a vegan cheese substitute.
Step-by-step instructions
- Add the diced potatoes and chopped onion to the crockpot. Pour in the 3 cups of broth and give everything a quick stir.
- Cover and cook on low for 6–8 hours or on high for 3–4 hours. Potatoes should be fork-tender.
- With a potato masher, mash some (not all) of the potatoes in the pot to create a thicker, creamier texture while leaving chunks for bite.
- Stir in the heavy cream and shredded cheese until melted and combined. Taste and season with salt and pepper.
- Serve hot, garnished with chopped green onions or chives.

Storage and reheating tips
Cool quickly: refrigerate within 2 hours of cooking in shallow containers.
Refrigeration: keep in an airtight container for up to 3–4 days.
Freezing: portion into freezer-safe containers and freeze up to 2–3 months. Note that dairy (especially cream) can separate slightly after freezing; thaw overnight in the fridge and whisk well when reheating.
Reheat on the stove over medium-low heat until steaming and uniform. Bring leftovers to at least 165°F (74°C) for food safety. Add a splash of broth or milk while reheating if the soup has thickened too much.
Creative twists
- Loaded baked potato: top each bowl with turkey bacon, chives, and a dollop of sour cream.
- Smoky version: add 1–2 smoked paprika teaspoons or a small diced smoked sausage in the pot for a smoky depth.
- Herb-forward: finish with fresh thyme or parsley for brightness.
- Vegan swap: use full-flavored cashew cream and nutritional yeast for cheesiness.
- Spicy kick: stir in a spoonful of chipotle in adobo or cayenne to heat things up.
Common questions
Can I use milk instead of heavy cream?
A: Yes. Whole milk or half-and-half works to lighten calories, but the soup will be thinner. If using milk, you can mash more potatoes or stir in a teaspoon of cornstarch mixed with cold water to thicken.
Will the cream separate if I freeze the soup?
A: Dairy can separate after freezing. To minimize this, cool and freeze quickly, then thaw in the refrigerator. Reheat slowly and whisk or blend to re-emulsify. Using full-fat dairy reduces separation.
How long does this keep in the fridge?
A: Store in an airtight container and eat within 3–4 days. Always reheat to 165°F (74°C) before serving.
Can I brown the onions first?
A: You can sauté the onion before adding to the crockpot for a deeper, sweeter flavor, but it’s not necessary — the slow cook does most of the flavor development.
Can I make this on the stovetop instead?
A: Absolutely. Simmer diced potatoes and onion in broth until tender (about 15–20 minutes), mash some potatoes, then stir in cream and cheese off heat.
