Why You'll Love This Recipe
About the Ingredients
3 pounds (1.36kg) russet potatoes, peeled and cut into 1-inch cubes
Russets break down beautifully and thicken the soup; for a waxy, chunkier texture, substitute Yukon Golds and reduce the cook time by about 30 minutes on low.
1 medium yellow onion, finely diced (about 1 cup / 160g)
Yellow onion gives the best balance of sweetness and bite; if you are short on time, use 1 cup of frozen chopped onion straight from the freezer.
3 cloves garlic, minced (about 1 tablespoon)
Fresh garlic is ideal, but 1 teaspoon of garlic powder can stand in; add it with the broth so it does not scorch.
6 cups (1.42L) low-sodium chicken broth
Use vegetable broth to make it vegetarian; choose a low-sodium brand so you can control the salt level at the end.
1 teaspoon kosher salt, plus more to taste
Kosher salt dissolves evenly; if using fine table salt, start with 3/4 teaspoon since it is saltier by volume.
1/2 teaspoon freshly ground black pepper
Fresh-cracked pepper is far more aromatic than pre-ground; white pepper works if you want to keep the soup snowy white.
4 tablespoons (57g) unsalted butter
Butter adds a silky finish; for a lighter version, substitute 3 tablespoons of olive oil and stir in the cream at the end.
1 cup (240ml) heavy cream, warmed
Half-and-half or whole milk can replace the cream for a lighter soup, but warm it first so it does not curdle when it hits the hot broth.
2 cups (226g) shredded sharp cheddar cheese
Shred your own block cheddar for the smoothest melt; bagged pre-shredded cheese contains anti-caking starch that can turn grainy.
1/4 cup (15g) chopped fresh chives or green onions, for garnish
Chives add a fresh oniony pop; crispy crumbled bacon or a dollop of sour cream are excellent stand-ins.
Tips & Tricks
Do not overcook the potatoes
Check them at the low end of the time range. Once they fall apart into mush, the soup turns gluey, so pull the lid off and mash as soon as a fork slides in easily.
Add dairy at the very end
Stirring cream and cheese into boiling-hot soup can cause curdling. Turn the slow cooker off, let it sit 5 minutes, then whisk in the dairy until smooth.
Season in layers
Salt the potatoes and broth at the start, then taste and adjust after the cheese goes in, since cheddar adds its own saltiness.
Mash for the right texture
Use a potato masher right in the crock for a rustic, chunky soup, or blend half the pot with an immersion blender for a creamier body.
Pro Tips
Step-by-Step Instructions
1. Load the slow cooker
Add the cubed potatoes, diced onion, garlic, chicken broth, kosher salt, and black pepper to a 6-quart slow cooker and stir to combine.
2. Cook on low
Cover and cook on LOW for 6 to 7 hours or on HIGH for 3 to 4 hours, until the potatoes are fork-tender and a cube crushes easily against the side of the pot.
3. Mash for texture
Turn the slow cooker off and mash about half the potatoes with a potato masher right in the pot, leaving plenty of chunks for body.
4. Melt in the butter
Stir in the butter until it melts completely and the broth looks glossy, about 1 minute.
5. Add the cream
Pour in the warmed heavy cream in a slow stream while stirring, then whisk until the soup is uniform and steaming but not boiling.
6. Melt the cheese
Add the shredded cheddar one handful at a time, stirring after each addition until fully melted and the soup turns velvety, about 2 to 3 minutes total.
7. Taste and season
Taste and add more salt and pepper as needed; the amount depends on the saltiness of your broth and cheese.
8. Serve hot
Ladle into bowls and top with chives, extra cheddar, bacon, or sour cream, and serve immediately.
Delicious Variations
Loaded Baked Potato
Top each bowl with crumbled bacon, sour cream, and extra chives for a baked-potato spin.
Broccoli Cheddar
Stir in 2 cups of small broccoli florets during the last 30 minutes on HIGH for a greener, heartier soup.
Spicy Southwest
Add a 4-ounce can of diced green chiles and 1 teaspoon of cumin with the broth, then finish with pepper jack instead of cheddar.
How to Store Easy Crockpot Potato Soup Recipe
Refrigerator
Store in an airtight container in the refrigerator for up to 4 days; the soup thickens as it chills, so loosen it with a splash of broth when reheating.
Freezer
Freeze in portions for up to 2 months, but note that dairy-based soups can separate; whisk vigorously while reheating and add a splash of cream to restore smoothness.
Reheating
Reheat gently on the stovetop over medium-low heat, stirring often, or in the microwave in 1-minute bursts; avoid boiling, which can make the dairy grainy.
Frequently Asked Questions
Q: Can I put raw potatoes in a crockpot for soup?
Yes, raw cubed potatoes cook perfectly in a slow cooker and are exactly what this recipe calls for. Cut them into even 1-inch pieces so they soften at the same rate, and never add them whole or they will take far too long.
Q: Why did my crockpot potato soup turn out gluey?
Overcooking and over-mashing are the usual culprits, because mashed potato starches turn pasty when beaten too much. Cook just until fork-tender and mash gently by hand rather than blending at high speed.
Q: Can I make this potato soup in a slow cooker without cream?
Yes, substitute whole milk or half-and-half, or use evaporated milk for a lighter but still creamy result. Add it at the very end off the heat so it does not curdle.
Q: How long does potato soup last in the fridge?
Leftover potato soup keeps for about 4 days in an airtight container in the refrigerator. Reheat it gently and stir well, since it thickens considerably when cold.
Q: Can I double this recipe in my crockpot?
You can double it only if you have a 7-quart or larger slow cooker, and you should add about 1 extra hour of cook time. Filling the pot more than three-quarters full prevents proper heat circulation.
