Easy Slow Cooker Loaded Potato Soup

This easy slow cooker loaded potato soup is the kind of comfort food that makes a weeknight feel cozy. Tender potatoes simmer in a savory broth until soft, then get mashed and blended with cream cheese and milk for a thick, creamy base. Crispy bacon, sharp cheddar, and green onions go on top, just like a loaded baked potato.

Most of the work happens in the slow cooker, so you can set it in the morning and come home to a hot, hearty dinner. It works well for family dinners, potlucks, and make-ahead lunches.

Why You’ll Love This Recipe

• Hands-off cooking: The slow cooker does most of the work while you go about your day.
• Simple ingredients: You likely have most of these staples on hand.

Ingredients

• 2 lb (900 g) russet potatoes, peeled and cut into 1/2-inch cubes (about 4 medium)
• 1 small yellow onion, finely diced (about 1 cup or 150 g)
• 3 cloves garlic, minced
• 4 cups (960 ml) low-sodium chicken broth
• 1 tsp kosher salt, plus more to taste
• 1/2 tsp black pepper
• 4 oz (115 g) cream cheese, softened
• 1 cup (240 ml) half-and-half
• 1 1/2 cups (150 g) shredded sharp cheddar cheese, divided
• 6 slices bacon, cooked until crisp and crumbled
• 2 green onions, thinly sliced, for garnish
• Sour cream, for serving (optional)

Ingredient Notes

Russet potatoes are starchy and break down easily, which helps the soup turn creamy. Waxy potatoes hold their shape better, so they are less ideal here.

Cream cheese adds body and richness without making the soup heavy. Softening it first helps it blend smoothly. Half-and-half works well, and whole milk can be used for a lighter version, though the soup will be less rich.

Sharp cheddar has a stronger flavor that stands up to the potatoes and bacon. Shred it yourself if you can, since pre-shredded cheese may not melt as smoothly.

Equipment You’ll Need

• Slow cooker (4-quart or larger)
• Potato masher or immersion blender
• Cutting board and sharp knife
• Large skillet (for bacon)
• Whisk or wooden spoon

How to Make Slow Cooker Loaded Potato Soup

1. Prepare the potatoes. Peel the potatoes and cut them into 1/2-inch cubes. Keep them roughly the same size so they cook evenly.
2. Add the base ingredients. Place the potatoes, diced onion, garlic, chicken broth, salt, and pepper in the slow cooker. Stir to combine.
3. Cook the soup. Cover and cook on low for 7 to 8 hours or on high for 3 to 4 hours. The soup is ready when a fork slides easily into a potato cube with no resistance.
4. Cook the bacon. While the soup cooks, fry the bacon in a skillet over medium heat for about 8 to 10 minutes, turning occasionally, until crisp. Drain on a paper towel and crumble once cool enough to handle.
5. Mash the soup. Use a potato masher to break up about half the potatoes right in the pot. Leave some chunks for texture. An immersion blender can be used for a smoother soup.
6. Add the dairy. Stir in the softened cream cheese and half-and-half until the cream cheese fully dissolves. Turn the slow cooker to low if it is not already on low and let the soup warm for about 15 to 20 minutes, stirring occasionally, until hot and smooth.
7. Melt the cheese. Stir in 1 cup (100 g) of the shredded cheddar until melted and glossy. Taste and adjust salt and pepper.
8. Serve. Ladle the soup into bowls. Top with the remaining cheddar, bacon, green onions, and sour cream if using.

Pro Tips for the Best Results

• Cut the potatoes into even cubes so they finish cooking at the same time.
• Avoid adding dairy at the beginning, since it can curdle or separate during long cooking.
• Season gradually. Broth and bacon both add salt, so taste before adding more.
• Shred cheddar from a block for a smoother, more even melt.
• Keep some potato chunks in the soup for a rustic texture rather than mashing everything.
• Add a splash of extra half-and-half if the soup thickens too much after it sits.

Common Mistakes to Avoid

Soup that is grainy or thin: Some potatoes may not have broken down enough. Mash more of them, or let the soup cook a bit longer before adding dairy.

Curdled or separated dairy: Adding milk or cheese too early or letting the soup boil after adding it can cause separation. Keep the heat low once the dairy goes in.

Soggy bacon: Adding bacon too early makes it lose its crunch. Stir it in just before serving or let guests add their own.

Overly salty soup: Broth and bacon vary in saltiness. Taste before adding the full amount of salt.

Variations and Substitutions

• Lighter version: Replace the half-and-half with whole milk and use reduced-fat cream cheese.
• Vegetarian option: Use vegetable broth and skip the bacon, or use smoked paprika for a smoky flavor.
• Extra veggies: Add 1 cup of chopped carrots or celery at the start of cooking.
• Ranch-style toppings: Top with a spoonful of ranch dressing or chives for a different flavor.
• Different cheese: Monterey Jack or a sharp white cheddar works well in place of the cheddar.

Serving Suggestions

Serve the soup with crusty bread, a simple green salad, or buttery rolls for dipping. Garlic bread or cornbread also pairs well. For a complete meal, add a side of roasted green beans.

Storage and Reheating

Store leftover soup in an airtight container in the refrigerator for up to 3 to 4 days. Freezing is possible, but the dairy may separate and the texture can become grainy after thawing. If you plan to freeze, leave out the cream cheese and half-and-half, then stir them in after reheating.

Reheat portions gently on the stovetop over medium-low heat, stirring often. Add a splash of broth or milk if the soup has thickened in the fridge.

Frequently Asked Questions

Can I make this soup ahead of time?

Yes. Cook the potato base ahead, then refrigerate it. Reheat and add the dairy and cheese just before serving for the best texture.

Can I freeze loaded potato soup?

You can freeze the soup without the dairy. Add the cream cheese, half-and-half, and cheese after thawing and reheating.

Why is my potato soup too thin?

The soup may need more mashing. Mash more potatoes or let it cook longer on low before adding the dairy to help it thicken.

How do I know when the potatoes are done?

The potatoes are done when a fork slides into them with little resistance and they start to break apart easily.

Can I use frozen potatoes?

Frozen diced potatoes can be used, but the texture may be softer and the cooking time may be shorter. Check for doneness earlier than the recipe suggests.

What can I substitute for cream cheese?

Sour cream can be used, but add it at the end and do not boil it, since it can curdle. Plain Greek yogurt also works in a similar way.
