Ingredient Notes and Substitutions

Russet Potatoes

Russet potatoes break down easily and help create a naturally thick soup.

Yukon Gold potatoes can also be used, but they generally retain their shape more firmly and produce a slightly different texture.

Chicken Broth

Low-sodium chicken broth adds flavor while giving you more control over the salt.

Vegetable broth can be used if the remaining ingredients also suit your dietary preferences.

Heavy Cream

Heavy cream gives the soup a rich finish. Half-and-half may produce a lighter, thinner soup.

Cheddar Cheese

Sharp cheddar provides a pronounced cheese flavor. Shred the cheese from a block so it melts more smoothly.

Sour Cream

Sour cream adds creaminess and the tang associated with a loaded baked potato.

Bacon

Cook the bacon separately until crisp. Do not add uncooked bacon as a final topping.

How to Make Slow Cooker Loaded Baked Potato Soup

Step 1: Prepare the Potatoes

Wash and peel the potatoes.

Cut them into similarly sized pieces, approximately ¾ inch each. Even pieces cook more consistently.

Place the potatoes inside the slow cooker.

Step 2: Add the Aromatics and Broth

Add the diced onion, minced garlic, chicken broth, salt, black pepper, and dried thyme.

Stir briefly to distribute the seasonings.

The broth may not completely cover every potato. The potatoes will release moisture and settle as they cook.

Step 3: Slow-Cook the Potatoes

Cover the slow cooker.

Cook on:

Low for approximately 6 to 7 hours, or
High for approximately 3 to 4 hours.

The potatoes should be completely tender and easy to crush with a fork.

Cooking time varies according to the slow-cooker model and the size of the potato pieces.

Avoid repeatedly lifting the lid, as this releases heat and can extend the cooking time.

Step 4: Mash Some of the Potatoes

Use a potato masher to mash approximately half of the potatoes directly inside the slow cooker.

Leave the remaining pieces intact for texture.

For a smoother soup, blend a portion carefully with an immersion blender. Avoid blending excessively because potatoes can become gluey.

Step 5: Add the Cream, Cheese, and Sour Cream

Set the slow cooker to low if it was cooking on high.

Add the heavy cream gradually and stir.

Add the shredded cheddar in small amounts, stirring after each addition. Then mix in the sour cream.

Continue heating gently until the cheese melts and the soup is hot throughout.

Avoid aggressively boiling the soup after adding the dairy.

Step 6: Adjust the Consistency

If the soup is too thick, add a small amount of warm broth or milk.

If it is too thin, combine the cornstarch and cold water in a small bowl. Stir the slurry into the soup and cook until it thickens.

Taste and adjust the salt and black pepper.

Step 7: Add the Toppings and Serve

Ladle the hot soup into bowls.

Top each serving with cooked bacon, shredded cheddar, green onions, sour cream, and black pepper.

Serve immediately with bread, crackers, or a green salad.

Tips for the Best Potato Soup

Cut the Potatoes Evenly

Consistently sized pieces become tender at approximately the same time.

Use Freshly Shredded Cheese

Freshly grated cheese generally melts more smoothly than packaged shredded cheese.

Add Dairy Near the End

Cream, cheese, and sour cream do not need to cook for the full slow-cooker time.

Avoid High Heat After Adding Cheese

Strong boiling can cause dairy-based soups to separate or become grainy.

Mash Only Part of the Soup

Partially mashing thickens the broth while maintaining some potato texture.

Season Gradually

Broth, cheese, and bacon all contain salt. Taste before adding more.

Loaded Potato Soup Variations

Broccoli Cheddar Potato Soup

Add small steamed broccoli florets near the end of cooking.

Ham and Potato Soup

Add diced, fully cooked ham during the final heating stage.

Spicy Loaded Potato Soup

Add diced jalapeños, red pepper flakes, or Pepper Jack cheese.

Vegetarian Potato Soup

Use vegetable broth and omit the bacon. Check that all other toppings are suitable.

Extra-Cheesy Potato Soup

Add more cheese gradually, ensuring it melts smoothly before adding additional quantities.

Potato Soup Without Bacon

Leave out the bacon and add roasted vegetables, extra green onions, or toasted breadcrumbs.

What to Serve With Potato Soup

Serve it with:

Garlic bread.
Dinner rolls.
Grilled cheese sandwiches.
Garden salad.
Roasted broccoli.
Crackers.
Cornbread.
Crispy chicken tenders.
Air fryer chicken wings.
Sautéed green beans.

For an easy comfort-food dinner, pair the soup with garlic bread and a fresh salad.

How to Store and Reheat Leftovers

Allow leftover soup to cool before transferring it to an airtight container.

Refrigerate promptly and use within 3 to 4 days.

Reheat gently in a saucepan over medium-low heat, stirring frequently. Add a little broth or milk if the soup becomes too thick.

Heat leftovers to 165°F.

Avoid rapid boiling because the dairy can separate.

Can You Freeze Loaded Potato Soup?

Freezing is possible, but potatoes and dairy may develop a grainier texture after thawing.

If you plan to freeze it, consider freezing the soup before adding the cream, cheese, and sour cream. Add those ingredients after thawing and reheating.

Thaw frozen soup safely in the refrigerator.

Frequently Asked Questions

Do I Need to Boil the Potatoes First?

No. The raw potato pieces cook directly in the slow cooker with the broth.

Can I Leave the Potato Skins On?

Yes, particularly with thin-skinned potatoes. Wash and scrub them thoroughly first. Russet skins can create a more rustic texture.

Why Is My Potato Soup Too Thin?

The potatoes may need additional cooking or mashing. You can also add a cornstarch slurry gradually.

Why Is My Soup Grainy?

The dairy may have been heated too aggressively, or packaged cheese may not have melted smoothly.

Can I Use an Immersion Blender?

Yes. Blend only part of the soup unless you want a completely smooth texture.

Can I Add Raw Bacon to the Slow Cooker?

For predictable texture and food safety, cook the bacon separately before using it as a topping.

Can I Make This Without Heavy Cream?

You can use another suitable dairy ingredient, but the consistency and richness will change.
