The Ingredients

This recipe uses simple, wholesome ingredients that come together beautifully.

2 pounds cubed Mountain Rose potatoes – These rosy-skinned potatoes have creamy, yellow flesh that cooks up velvety smooth. Yukon Gold or russet work too.
4 cups chicken broth – For savory depth. Vegetable broth works for a vegetarian version.
4 cloves garlic, minced – For warm, aromatic depth.
1½ cups heavy cream – For luxurious richness. Don’t substitute milk or half-and-half—the soup won’t be as silky.
1½ teaspoons kosher salt – Seasons the soup.
½ teaspoon black pepper – Adds warmth.
2 tablespoons butter, optional – For extra richness.
Chopped chives, shredded cheddar, or cooked bacon for serving, optional – For toppings.

Step-by-Step Instructions

Step 1: Add Everything to the Slow Cooker

Add the cubed Mountain Rose potatoes, chicken broth, minced garlic, salt, and black pepper to a 6-quart oval slow cooker. Stir once to combine, cover, and cook on low for 6 to 7 hours or on high for 3 to 4 hours, until the potatoes are very tender.

Pro Tip: Cut the potatoes into uniform cubes so they cook evenly.

Step 2: Blend the Soup

Once the potatoes are soft, use an immersion blender to blend the soup directly in the slow cooker until mostly smooth and velvety, leaving just a little texture if you like. If using butter, blend that in now.

Pro Tip: If you don’t have an immersion blender, carefully transfer the soup to a stand blender in batches. Be careful—hot soup expands!

Step 3: Stir in the Cream

Stir in the heavy cream, cover again, and cook on low for 15 to 20 minutes more, just until heated through. Do not boil after adding the cream.

Pro Tip: Keep the heat low after adding the cream. Boiling can cause the cream to curdle.

Step 4: Taste and Serve

Taste and adjust seasoning if needed, then ladle into bowls and serve hot with any toppings you like.

Pro Tip: Serve with crusty bread for dipping and your favorite toppings.
