How to Make Slow Cooker Potato Soup
1. Prepare the Potatoes
Peel the potatoes and cut them into small, evenly sized cubes.
Keeping the pieces similar in size helps them cook at the same rate.
2. Add Everything to the Slow Cooker
Place the potatoes, onion, and garlic into a 6-quart slow cooker.
Pour in the chicken or vegetable broth.
Add the salt, black pepper, parsley, thyme, paprika, and butter.
Stir everything together.
3. Slow Cook
Cover and cook on:
- Low for 6–8 hours, or
- High for 3–4 hours
The potatoes should be completely tender and easy to pierce with a fork.
4. Blend Part of the Soup
For a naturally creamy texture, use a potato masher to mash some of the potatoes directly in the slow cooker.
Leave some potato pieces whole for texture.
If you prefer a completely smooth soup, use an immersion blender, but don’t overblend because potatoes can become gluey.
5. Make It Creamy
About 20–30 minutes before serving, stir in the milk and heavy cream.
If you’d like a thicker soup, whisk the flour with a few tablespoons of cold milk until smooth before adding it to the slow cooker.
Stir well.
6. Add the Cheese
Add the shredded cheddar and stir until completely melted.
Taste and adjust the salt and pepper as needed.
Allow the soup to heat for another 15–20 minutes, but avoid aggressively boiling the soup after adding the dairy.
How to Serve
Ladle the hot potato soup into bowls and top with your favorite combination of:
- Crispy bacon
- Cheddar cheese
- Green onions
- Sour cream
- Fresh parsley
- Cracked black pepper
For an extra comforting meal, serve it with warm crusty bread, garlic bread, or homemade dinner rolls.
Tips for the Best Slow Cooker Potato Soup
Choose the Right Potatoes
Yukon Gold potatoes create a naturally creamy soup while holding their shape well.
Russet potatoes break down more easily and are excellent if you want a thicker, creamier soup.
Cut the Potatoes Evenly
Large chunks will take longer to cook, while very small pieces can break down completely.
Aim for roughly 1-inch cubes.
Don’t Add Dairy Too Early
Milk and cream can separate or develop an unpleasant texture during a long slow-cooking process.
For the best results, add them toward the end.
Don’t Overblend
If you’re using an immersion blender, blend only part of the soup. A mixture of creamy broth and tender potato chunks gives the soup a much better texture.
Easy Variations
Loaded Baked Potato Soup
Add crispy bacon, extra cheddar, sour cream, and green onions before serving.
Chicken Potato Soup
Add 2 cups of cooked shredded chicken during the final 30 minutes.
Ham and Potato Soup
Stir in diced cooked ham for a smoky, savory variation.
Garlic Potato Soup
Increase the garlic and add a little roasted garlic for deeper flavor.
Vegetable Potato Soup
Add carrots, celery, corn, or peas for extra vegetables.
Extra Cheesy Potato Soup
Use a combination of cheddar, Monterey Jack, and a little Parmesan.
Make-Ahead Instructions
Prepare the soup through the potato-cooking stage and refrigerate it once cooled.
When ready to serve, reheat gently on the stovetop or in the slow cooker, then add the milk, cream, and cheese toward the end.
This approach can help maintain a better creamy texture.
Storage
Allow leftovers to cool and refrigerate them in an airtight container for up to 3–4 days.
Reheat gently, stirring occasionally.
If the soup becomes too thick in the refrigerator, add a splash of milk or broth while reheating.
Because dairy-based potato soups can change texture when frozen and thawed, freezing is generally not the best option if you want the original creamy consistency.
Frequently Asked Questions
Can I make this soup without cream?
Yes. You can use additional milk, evaporated milk, or simply add more broth and mash more of the potatoes to create a creamy texture.
Can I use milk instead of heavy cream?
Yes. The soup will be lighter and less rich, but it will still be delicious.
Can I leave the potato skins on?
Yes, especially when using thin-skinned Yukon Gold or red potatoes. Just scrub them thoroughly first.
Can I make it vegetarian?
Absolutely. Use vegetable broth instead of chicken broth and choose vegetarian-friendly toppings.
How do I make it thicker?
Mash more of the potatoes directly in the slow cooker. You can also add a small amount of flour or cornstarch slurry near the end.
Final Thoughts
