Slow Cooker Baked Potato Soup

I make this slow cooker baked potato soup when I want something warm, filling, and familiar without standing over the stove. It is one of those comforting soups that feels like it has always belonged at the table.

The soup cooks up thick and creamy with tender potatoes, rich broth, and just the right balance of cheese and cream. Finished with bacon, chives, and extra cheese, it tastes just like a loaded baked potato in a bowl.

It reminds me of the kind of soup Grandma would make on chilly evenings, served with big bowls and plenty of toppings to pass around.

What You Need to Know

  • This soup is thick, creamy, and hearty
  • Leftovers store well and reheat gently
  • It can be made ahead and tastes even better the next day
  • You can adjust the toppings to suit your table

Ingredients Overview

  • Russet potatoes: Break down slightly and give the soup its classic texture
  • Onion and garlic: Add savory depth as the soup cooks
  • Chicken broth: Creates a flavorful base
  • Butter: Adds richness to the soup
  • Heavy cream or half and half: Makes the soup smooth and creamy
  • Sharp cheddar cheese: Adds that classic baked potato flavor
  • Chives or green onions: Bring a fresh finish
  • Sour cream: Optional but adds tang and creaminess
  • Bacon: A classic topping that adds crunch and smoky flavor

How to Make Slow Cooker Baked Potato Soup

Step 1: Add the potatoes, chopped onion, chicken broth, minced garlic, butter, salt, and pepper to a large crock pot. Cover and cook on High for 4 hours or on Low for 8 hours, until the potatoes are very tender.

Step 2: Using a potato masher, mash the soup until the potatoes are coarsely broken down and the soup begins to thicken. Leave some chunks for texture.

Step 3: Stir in the heavy cream, shredded cheddar cheese, and chopped chives. Mix until the cheese melts and the soup is smooth and creamy.

Step 4: Ladle the soup into bowls and top with sour cream if using, crumbled bacon, extra cheese, and more chives before serving.

Grandma’s Tips

  • Mash gently so the soup stays thick but not gluey
  • Taste before serving and adjust salt if needed

Modern Updates

  • Use half and half instead of heavy cream for a lighter bowl
