Creamy Slow Cooker Potato Soup with Bacon

There’s no duplicate in the Yummizer recipe history I have for Creamy Slow Cooker Potato Soup with Bacon, so this is a good one to add. It also gives us a strong cozy fall/winter slow-cooker recipe without overlapping with your existing lasagna soup or chicken chili recipes.

This Creamy Slow Cooker Potato Soup with Bacon is the kind of dinner made for cold, busy evenings. Tender potatoes slowly cook with onion, garlic, and savory broth until everything becomes rich and comforting, then cream and cheese turn the soup beautifully smooth without losing those satisfying pieces of potato.

Crispy bacon is the finishing touch, adding smoky, salty crunch against the creamy soup. Best of all, most of the cooking happens right in the Crockpot, making this an easy hands-off dinner you can start earlier in the day and finish just before serving.

Easy Creamy Slow Cooker Potato Soup with Bacon

Potato soup doesn’t need complicated ingredients to taste great. The best versions rely on simple ingredients cooked properly: starchy potatoes, aromatic onion and garlic, good broth, cream, cheese, and enough seasoning to keep everything balanced.

Using the slow cooker makes the process particularly convenient because the potatoes have several hours to become tender while absorbing the flavor of the broth and aromatics.

Instead of blending the entire soup completely smooth, we’ll mash only some of the cooked potatoes. That naturally thickens the broth while leaving plenty of tender potato pieces behind.

If you enjoy letting the slow cooker handle dinner, our Cozy Crockpot Chicken and Wild Rice Soup is another comforting option for busy evenings.

Ingredients

Russet Potatoes

You’ll need about 2½ pounds russet potatoes, peeled and cut into roughly ¾-inch cubes.

Russets work especially well because their high starch content helps naturally thicken the soup.

Bacon

Use 8 slices thick-cut bacon.

Cook it until crisp before adding it to the finished soup. Keeping the bacon out of the slow cooker prevents it from becoming soft and rubbery.

Yellow Onion

One medium yellow onion gives the soup a savory base.

Dice it fairly small so it becomes tender during slow cooking.

Garlic

Use 3 cloves fresh garlic, minced.

Chicken Broth

You’ll need 4 cups low-sodium chicken broth.

Using low-sodium broth gives you more control over the final seasoning, especially because bacon and cheese already contribute salt.

Butter

Use 2 tablespoons unsalted butter for extra richness.

Dried Thyme

A small amount of thyme adds savory flavor without overpowering the potatoes.

Smoked Paprika

Just ¼ teaspoon complements the bacon and adds subtle depth.

Salt and Black Pepper

Season conservatively at the beginning and adjust near the end.

Heavy Cream

Use 1 cup heavy cream.

Add it toward the end rather than cooking it for the entire slow-cooker period.

Sour Cream

Use ½ cup sour cream for creaminess and a subtle tang.

Cheddar Cheese

Use 1 cup freshly shredded sharp cheddar cheese.

Freshly grated cheese generally melts more smoothly than pre-shredded cheese.

Cornstarch

Use 2 tablespoons cornstarch mixed with 2 tablespoons cold water.

This is optional but useful if you prefer a particularly thick soup.

Green Onions

Fresh sliced green onions add color and freshness when serving.

How to Make Slow Cooker Potato Soup

1. Prepare the potatoes

Peel the potatoes and cut them into approximately ¾-inch cubes.

Try to keep them relatively similar in size so they cook at roughly the same rate, but they don’t need to be perfectly uniform.

2. Add potatoes to the slow cooker

Transfer the cubed potatoes to a 6-quart slow cooker.

3. Add the aromatics

Add the diced onion and minced garlic.

4. Add the seasonings

Sprinkle in the dried thyme, smoked paprika, salt, and black pepper.

Start lightly with the salt because the bacon and cheddar will add more later.

5. Pour in the broth

Add the chicken broth.

The potatoes don’t necessarily need to be completely submerged.

6. Add butter

Place the butter over the potatoes.

7. Slow cook

Cover and cook on:

LOW for 6–7 hours

or

HIGH for 3–4 hours

The potatoes should be completely fork-tender.

8. Cook the bacon

Near the end of the cooking time, cook the bacon in a skillet until crisp.

Transfer it to a paper-towel-lined plate.

Once cool enough to handle, crumble or chop it into irregular pieces.

9. Mash some of the potatoes

Once the potatoes are tender, use a potato masher directly inside the slow cooker.

Mash approximately one-third to one-half of the potatoes.

Don’t mash everything.

Leaving some potato chunks creates a much more satisfying texture.

10. Add the cream

Pour in the heavy cream and gently stir.

11. Add sour cream

Stir in the sour cream until incorporated.

12. Add cheddar

Add the freshly shredded cheddar gradually while stirring.

Continue until melted.

13. Check the consistency

The mashed potatoes may already make the soup thick enough.

If you’d like it thicker, combine the cornstarch and cold water in a small bowl.

14. Add the slurry if needed

Stir the cornstarch slurry into the soup.

15. Finish cooking

Cover and cook on HIGH for another 15–20 minutes, until hot and creamy.

16. Add some bacon

Stir approximately half of the crispy bacon into the soup.

Reserve the remainder for topping.

17. Taste and season

Taste before adding additional salt.

Add more black pepper or salt as needed.

18. Serve

Ladle the soup into bowls and finish with crispy bacon, shredded cheddar, sliced green onions, and a small spoonful of sour cream if desired.

The Secret to Thick, Creamy Potato Soup

You don’t need to fill potato soup with flour to make it creamy.

Once russet potatoes cook until tender, their starch provides natural thickening power.

Mashing some—but not all—of them gives you both textures at once: a creamy broth and recognizable tender potato pieces.

The optional cornstarch slurry is there if you prefer an especially thick consistency.

Variations

Loaded Baked Potato Soup

Be generous with the cheddar, bacon, sour cream, and green onions when serving.

Ham and Potato Soup

Replace the bacon with diced cooked ham.

Potato and Corn Soup

Add about 1½ cups corn during the final 30 minutes.

Spicy Potato Soup

Add a pinch of cayenne or finely diced jalapeño.

Extra Cheesy Potato Soup

Increase the cheddar to 1½ cups.

Lighter Potato Soup

Replace the heavy cream with half-and-half. The finished soup won’t be quite as rich, but it will still be creamy.

Vegetarian Potato Soup

Use vegetable broth and omit the bacon.

Pro Tips

Cut potatoes relatively evenly. This helps them become tender at approximately the same time.

Don’t add dairy at the beginning. Cream and sour cream are best added toward the end.

Mash before adding the cheese. It’s much easier to control the final texture.

Shred your own cheddar. It tends to melt more smoothly.

Keep the bacon crisp. Add most of it at the end rather than slow-cooking it all day.

Season after adding the bacon and cheese. Both are salty.

Don’t over-blend. Completely blending potatoes can sometimes create a gluey texture.

Let the potatoes do most of the thickening. Add the cornstarch only if necessary.

What Are the Best Potatoes for Potato Soup?

Russet potatoes are my first choice for this recipe because they become soft and starchy during slow cooking.

That starch helps thicken the soup naturally.

Yukon Gold potatoes are another good option. They’ll hold their shape slightly better and produce a somewhat less starchy but naturally buttery soup.

You can even combine the two varieties if you want a balance of creaminess and defined potato chunks.

What to Serve with Potato Soup

This soup is filling enough to serve as dinner by itself, but simple sides work especially well:

• Crusty bread
• Garlic bread
• Dinner rolls
• Green salad
• Roasted broccoli
• Steamed vegetables
• Grilled cheese sandwich

Storage

Refrigerator

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

Refrigerate for up to 4 days.

Reheating

Reheat gently on the stovetop over medium-low heat or microwave individual portions.

If the soup becomes very thick after refrigeration, stir in a splash of broth or milk.

Freezing

Cream-based potato soups aren’t my favorite candidates for freezing.

The potatoes can become grainy and dairy may separate after thawing.

For the best texture, enjoy this soup fresh or refrigerated.

Make-Ahead Tips

You can chop the onion and cook the bacon ahead of time.

The bacon can be refrigerated separately so it stays as crisp as possible.

If you peel and cut the potatoes ahead, keep them submerged in cold water in the refrigerator for a short period to prevent browning. Drain them thoroughly before adding them to the slow cooker.

Frequently Asked Questions

Can I put raw potatoes directly into the slow cooker?

Yes. There’s no need to boil them first.

Do I need to peel the potatoes?

Not necessarily. Russet skins are more noticeable, so I prefer peeling them for a smoother soup. Yukon Gold potatoes can often be left unpeeled after thorough washing.

Can I use milk instead of heavy cream?

Yes, but the soup won’t be quite as rich. Whole milk or half-and-half works better than low-fat milk.

Can I make potato soup without bacon?

Absolutely. Simply leave it out.

Why is my potato soup watery?

Your potatoes may not have released enough starch. Mash more of them or use the optional cornstarch slurry.

Why is my potato soup too thick?

Stir in additional broth or milk until it reaches your preferred consistency.

Can I blend the soup?

You can use an immersion blender briefly, but don’t completely puree it. Over-processing cooked potatoes can create a gummy consistency.

When should I add the cheese?

Add it near the end after the potatoes are completely tender and partially mashed.

Can I leave this in the slow cooker on warm?

Yes, for a short period. Keep an eye on the consistency and stir occasionally.

Can I prepare it overnight?

Technically you can slow-cook the potato-and-broth base, but I wouldn’t leave the finished dairy-based soup cooking overnight. Add the cream, sour cream, cheese, and bacon near serving time.
