When the slow cooker lid lifts, the broth is savory and the potatoes are tender, but it doesn’t look like the thick, creamy soup you might be expecting yet. That’s on purpose. Cheesy Crock Pot Hamburger Potato Soup gets its creamy finish from a separate milk-and-flour mixture added near the end, not from asking dairy to spend hours cooking with the beef and vegetables.

I brown the beef first, then let the potatoes, carrots, and celery soften slowly in beef broth. The stovetop thickener takes only a few minutes, and the cheddar goes in after the slow cooker is turned off. That order gives you a soup that’s hearty without turning the potatoes to paste or leaving the cheese grainy. Each bowl is creamy around tender chunks of potato, with beef and sharp cheddar in every spoonful.

Why the Flour-and-Milk Thickener Waits Until the Potatoes Are Tender

The slow cooker does the slow work of softening the vegetables and building a beefy broth. The flour thickener has a different job: it gives the finished soup a creamy body. Cooking butter and flour together on the stove first lets the flour cook for a minute before milk goes in, then the mixture thickens in just a few minutes of stirring.

Add that mixture near the end, once the potatoes are already tender. If it went in at the beginning, it would spend hours cooking with the broth and vegetables, when the soup still needs to stay loose enough for the potatoes to cook evenly. The late addition also makes it easier to judge the finish: after the final short stretch on HIGH, the soup should be hot and just a little thicker, not as dense as a casserole filling.

The cheddar has an even shorter job. It melts into the hot soup after the slow cooker is off, so the cheese adds a smooth, savory finish rather than sitting through a long cook.

What Builds the Beefy Base and Creamy Cheddar Finish

• Ground beef — The 85% lean beef gives the broth a rounded, meaty flavor without making the soup overly rich. A store-brand package works just as well as a pricier one; browning it thoroughly is what builds the savory base.
• Yukon Gold potatoes — Their creamy texture holds up well in the slow cooker while still giving the broth some body. Russets can be used, but they’re starchier and more likely to soften and break apart, so the finished soup will be less chunky.
• Yellow onion, garlic, carrots, and celery — These build the soup’s background flavor and give each spoonful some sweetness and bite. Cut the carrots and celery into similar-sized pieces so they soften at a similar pace.
• Beef broth and Worcestershire sauce — The broth is the main cooking liquid, while Worcestershire adds a tangy, savory depth. A basic store-brand broth is fine here; choose a broth you like drinking because its flavor carries through the whole pot.
• Butter, flour, and whole milk — Butter and flour form the stovetop thickener, and whole milk makes it creamy without relying on cream. A gluten-free cup-for-cup flour blend can replace the all-purpose flour; use it in the same way for a gluten-free variation.
• Sharp cheddar — Sharp cheese gives the soup a distinct cheddar flavor against the beef and potatoes. A block of cheddar is a good choice when you want the smoothest melt, while the FAQ below covers using packaged shredded cheese.

The Slow-Cooker Stages That Give the Soup Its Texture

Brown the Beef, Then Soften the Aromatics

Set a 12-inch skillet over medium-high heat and brown the ground beef, breaking it into small pieces, for 6 to 8 minutes, until it reaches 160°F. Drain the excess fat, then add the diced onion and cook for 4 to 5 minutes, until softened. Stir in the minced garlic for 30 seconds. Keep the garlic moving; it needs only a brief time in the hot skillet.

Load the Slow Cooker With the Broth Base

Put the cubed Yukon Gold potatoes, carrots, and celery in a 6-quart slow cooker. Add the browned beef mixture, beef broth, Worcestershire sauce, kosher salt, and black pepper. Stir gently so the seasonings and broth are distributed around the vegetables. The potatoes should be cut into even half-inch cubes so they soften at a similar pace.

Cook Until a Fork Slides Into the Potatoes

Cover the slow cooker and cook on LOW for 6 to 7 hours or HIGH for 3 to 4 hours. The clearest doneness cue is the potatoes: a fork should pierce a cube easily, without the center feeling firm. Check a few pieces from different parts of the cooker, since vegetables near the edge may cook differently from those in the middle. Keep the lid on during cooking so the slow cooker holds its heat.

Whisk a Smooth Milk Thickener

Near the end of the slow-cooking time, melt the butter in a medium saucepan over medium heat. Whisk in the flour and cook for 1 minute, then gradually whisk in the milk. Stir for 4 to 6 minutes, until the mixture thickens and looks smooth. Adding the milk gradually while whisking helps prevent floury lumps.

Finish With the Cheddar

Stir the thickened milk mixture into the slow cooker, cover, and cook on HIGH for 15 to 20 minutes, until the soup is hot and slightly thickened. Turn off the slow cooker before adding the shredded cheddar. Stir it in a handful at a time, giving each addition a chance to melt before adding the next.

Equipment

• 1 12-inch skillet

Method

 

1. In a 12-inch skillet over medium-high heat, brown the ground beef, breaking it into small pieces, for 6 to 8 minutes, until it reaches 160°F; drain excess fat.
2. Add the onion and cook for 4 to 5 minutes until softened.
3. Stir in the garlic for 30 seconds.
4. Put the potatoes, carrots, and celery in a 6-quart slow cooker.
5. Add the beef mixture, beef broth, Worcestershire sauce, salt, and pepper.
6. Cover and cook on LOW for 6 to 7 hours or HIGH for 3 to 4 hours, until the potatoes are tender when pierced with a fork.
7. Near the end of the cooking time, melt the butter in a medium saucepan over medium heat.
8. Whisk in the flour and cook for 1 minute.
9. Gradually whisk in the milk and cook, stirring, for 4 to 6 minutes until thickened.
10. Stir the milk mixture into the slow cooker, cover, and cook on HIGH for 15 to 20 minutes, until the soup is hot and slightly thickened.
11. Turn off the slow cooker and stir in the cheddar a handful at a time until melted.

Notes

For the smoothest texture, turn off the slow cooker before adding the cheddar and stir it in gradually. Refrigerate leftovers for 3 to 4 days; freezing is not recommended because the potatoes and dairy can become grainy. For a gluten-free variation, use a gluten-free 1:1 flour blend.
