This recipe for crockpot potato soup is made simply in your slow cooker and thickened with a bacon and cheese sauce made in under five minutes on the stovetop. Made completely from scratch without canned soup or cream cheese, it is thick, creamy, and packed with loaded baked potato flavor.
In testing how to make the perfect creamy potato soup recipe in a slow cooker, I decided to combine two methods from two of my most popular soup recipes: my slow cooker broccoli cheddar soup and my New England clam chowder. The chowder uses fat rendered from bacon to make a roux which thickens the soup. The broccoli cheddar soup cooks the base of the soup in the slow cooker and then adds a creamy roux at the end to bring the whole thing together.
In this recipe, we are making a roux on the stovetop near the end of the soup’s cook time using fat rendered from bacon. Then we mix in cream and shredded cheese and add it all back to the crockpot. The result is a silky smooth and creamy potato soup that you will want to make again and again.
If you love this recipe but want to make a stovetop spin on it, you could make my creamy potato soup with bacon or my ham and potato soup.
So delicious!!! 10/10 recommend! Even my VERY picky son loved it, he even had seconds! Absolutely the best potato soup I’ve had! I’m looking forward to doubling the recipe to serve to my family coming for the holidays! Thank you for sharing!
Why This Recipe Works
- Made completely from scratch: No canned soup or cream cheese.
- Filled with flavor: The base of the roux is formed with bacon grease instead of butter.
- Thick and creamy: Russet potatoes and the roux give the soup a creamy texture without making it gluey.
- Flexible cooking time: The soup can be cooked on high for three hours or on low for six hours.
- Loaded baked potato flavor: Bacon, cheddar cheese, sour cream, and green onions give the soup that classic loaded potato flavor.
Ingredients and Notes
- Russet potatoes: Their high starch content helps give this soup its thick, creamy texture You could also use Yukon Gold potatoes.
- Chicken broth: This can be made with 4 – 6 cups chicken broth. Four cups of broth give you a thick soup, while six cups of broth make a thinner soup.
- Bacon: Not only does it add flavor to the soup, but we use the rendered fat to make a roux, which gives the soup its thick, creamy texture without needing canned cream soup.
- Flour: Combines with the bacon fat to make a roux.
- Heavy cream: Adds a smooth, rich consistency to the soup base.
- Cheddar cheese: Freshly grated from a block of cheese will melt and taste much better than pre-shredded cheese.
How to Make Potato Soup in the Crockpot
- Combine the potatoes, onion, chicken broth, salt, and pepper in the slow cooker and cook on low for six hours or on high for three hours.
- Towards the end of the soup’s cooking time, in a saucepan on the stovetop, cook some diced bacon. Once crispy, leave the bacon and rendered fat in the pan. They will be used to make the roux.
- Whisk the flour into the cooked bacon and fat. Slowly add the cooking liquid from the slow cooker.
- Add cream and shredded cheese to the roux. Doing this on the stovetop will melt the cheese quickly. Then add the roux back to the slow cooker.
- Use an immersion blender to blend just until the soup becomes smooth being careful not to over-blend.
How to Make Crockpot Potato Soup Thick and Creamy
The key to a perfect creamy soup is a roux, a thickening mixture made from fat and flour. Cooking the flour in the rendered bacon fat allows it to combine smoothly with the broth, thickening the soup without lumps while adding extra bacon flavor.
Potatoes for Potato Soup
This soup calls for Russet potatoes. Their high starch content helps give the soup its creamy texture, especially if you blend or mash the potatoes at the end. You could also use Yukon Gold potatoes, which have a buttery texture and tend to hold their shape a little better if you prefer chunks of potato in your soup.
Keep in mind that the smaller you dice the potatoes, the quicker they will cook. If you like chunks of potato in your potato soup, consider the size of potato you prefer in each bite. For either type of potato, the pieces should be fork-tender before you finish the soup. Since slow cookers can vary, be sure to check that your potatoes can be easily mashed with a fork before adding the roux.
Tips and Substitutions
- Cut the potatoes evenly: Cut your potatoes into approximately 1 1/2-inch cubes so they cook at the same rate. Larger pieces may take longer to become fork-tender.
- Make a vegetarian potato soup: Use vegetable broth as the soup base and butter to make your roux instead of bacon grease. Instead of cooking bacon, melt a little less than two tablespoons of butter in the stockpot and continue with the recipe as written.
- Save some of the bacon: Make extra bacon and set it aside for garnishing your soup.
FAQ
This is a thick, creamy soup when made with four cups of broth. If you want a thinner soup, I would use six cups of chicken broth.
I love the smooth texture that blended potato soup gives. If you like chunks of potato in your soup, you can skip blending it or use a potato masher to mash the potatoes to your desired thickness.
Storing Leftovers
This soup makes great leftovers. In fact some readers have told me it is even better the next day. Store in your refrigerator in an airtight container for three to four days. When you want to reheat, take out the portion you plan on eating and heat over very low heat, stirring often so the soup doesn’t separate.
Freezing
Cream-based soups are not my favorite to freeze. That being said, it can be done. Once the soup has cooled completely, transfer it to a container with room for the soup to expand. Freeze it for up to three months. When you are ready to eat it, allow it to thaw in the refrigerator overnight and reheat over low heat on the stovetop, stirring often.
Reheating Leftovers
Reheat leftover potato soup at a low temperature so that it doesn’t separate. Either cook it covered in the microwave at half power, stirring halfway through, or cook it over very low heat on the stovetop, stirring often. Add some broth or milk to thin the soup, as it may thicken as it sits. Remember that leftovers should never be reheated more than once.

Notes

Hey, we are in our late seventies and early eighties , so I am needing some recipes with less calories and less cheese! My real problem is simple cooking! I don’t trust myself with knowing when things are done! Several of my friends are saying the same thing but we want this to be a secret! I need basic help like: baked chicken breast, baked salmon, meat balls , grilled chicken, canned tuna salad! Thanks!🙏Have a blessed day
Thank you so much for this great comment Sandy! I’m adding all these recipes to my “to make” list. In the meantime, try some of these: Oven Baked Chicken Thighs, Italian Meatballs, Grilled Chicken, Tuna Pasta Salad.
Mel says
Has anyone tried it with vegetable stock instead of chicken broth? Thank you so much.
S Pierce says
I have NEVER added flour to my soup. My son made potato soup the other day with canned diced potatoes (saved having to steam potatoes). Cook bacon, after bacon cooked, put potatoes and onions in bacon fat and stir until coated. Add milk, butter, velveeta. Best soup ever. No offense to you, I’m sure yours is good too, but this is so much faster.
Connie says
I have a probably dumb question. Do you use all the fat from the bacon you cook?
Not a dumb question at all! Yes! You will need all the fat from the bacon to make the roux.
Kassidy says
We made this for our weekly “Soup Sunday” and loved it. We halved it as there’s only 2 adults and a toddler, and we still had leftovers for lunch the next day! Will definitely be making again. :)
I’m so glad to hear you liked it, Kassidy! Nothing makes me happier than helping feed young families.
Lisa says
I don’t have any heavy cream! Could I use milk instead?
Sharon Tucket says
I am going to try this this week. Sounds delicious
Sunny says
I happen to have duck fat in my fridge. I know Duck Fat and potatoes are a marriage made in heaven. So, maybe do half the bacon fat and add in the duck fat.
What is your thoughts on this?
I haven’t actually cooked with duck, but I do think this will work! Let me know how it turns out.
Bruce says
Do you have to peel the potatoes?
You don’t have to, but I recommend that you do.
Lindsey says
Could you use frozen diced potatoes?
I haven’t tested that but I’m sure it will work just fine.
