Crockpot Potato Broccoli Cheddar Soup Recipe

I made Slow Cooker Potato Broccoli Cheddar Soup and it came out stupidly creamy and cheesy, the kind of bowl that demands seconds.

I’m obsessed with this Crockpot Potato Broccoli Cheddar Soup because it tastes like a big, sloppy bowl of comfort without the fuss. I love the way cheddar melts into russet potatoes and the broccoli florets still snap a little.

It’s thick, cheesy, and a little salty in the best way. And sometimes I crave the kind of Broccoli Cheddar And Potato Soup that actually fills you up.

This Slow Cooker Potato Broccoli Cheddar Soup hits that spot every time. No pretense.

Just rich, chunky soup that makes dinner feel worth it. I spoon it fast, no patience required at night.

Ingredients

• Russet potatoes: creaminess and body, makes it hearty.
• Broccoli florets: fresh green bite and texture contrast.
• Yellow onion: sweet base, gives cozy savory depth.
• Garlic: warm little kick, smells like home.
• Chicken or veggie broth: salty liquid backbone, keeps it cozy.
• Whole milk: light creaminess, keeps soup silky.
• Heavy cream: rich, velvety mouthfeel you’ll love.
• Unsalted butter: smooth fat that rounds flavors out.
• All purpose flour: thickens gently, no weird sliminess.
• Sharp cheddar: tangy, melty cheese hug in every spoonful.
• Salt: wakes everything up, don’t skimp a little.
• Black pepper: little heat and earthy edge.
• Dry mustard or Dijon: basically brightens the cheese notes.
• Paprika: mild color and soft smoky hint.

  Plus, pretty.

• Fresh parsley: bright green finish and fresh lift.
• Optional tweaks: small additions that personalize your bowl.

Ingredient Quantities

• 2 lb russet potatoes, peeled and diced (about 4 cups)
• 6 cups broccoli florets (from 2 heads)
• 1 cup chopped yellow onion (about 1 medium)
• 3 cloves garlic, minced
• 4 cups low sodium chicken broth or vegetable broth
• 1 cup whole milk
• 1 cup heavy cream
• 3 tablespoons unsalted butter
• 1/4 cup all purpose flour
• 2 cups shredded sharp cheddar cheese, packed
• 1/2 teaspoon salt, plus more to taste
• 1/4 teaspoon black pepper, plus more to taste
• 1/2 teaspoon dry mustard powder or 1 teaspoon Dijon mustard (optional, but helps flavor)
• 1/4 teaspoon paprika (optional)
• 2 tablespoons chopped fresh parsley for garnish (optional)

How to Make this

1. Melt butter in a medium skillet over medium heat, add chopped onion and cook until soft and translucent about 5 minutes, then stir in minced garlic and cook another 30 seconds until fragrant.

2. Sprinkle the flour over the onion mixture and cook, stirring constantly, for 1 to 2 minutes to get rid of the raw flour taste.

3. Slowly whisk in the whole milk and heavy cream right in the skillet until smooth and slightly thickened, then remove from heat.

4. Transfer the milk mixture to the crockpot and add diced potatoes, chicken or vegetable broth, salt, pepper, mustard powder or Dijon, and paprika; stir to combine.

5. Cook on LOW for 7 to 8 hours or on HIGH for 3 to 4 hours, until the potatoes are very tender. Tip: if you want quicker weeknight timing use HIGH and check at 3 hours.

6. With the potatoes tender, mash about a third of them right in the crockpot with a potato masher or the back of a spoon to naturally thicken the soup, leaving the rest chunky.

7. Stir in the broccoli florets, cover, and cook another 25 to 35 minutes on HIGH or 45 minutes on LOW, until broccoli is bright green and tender but not mushy.

8. Turn the crockpot to LOW or OFF and gradually stir in the shredded sharp cheddar a handful at a time until melted and smooth; avoid boiling after adding cheese so it stays creamy. Tip: use freshly shredded cheese, pre-shredded can make the soup grainy.

9. Taste and adjust with more salt, pepper, or a splash of extra milk if it seems too thick; if it’s too thin simmer uncovered on HIGH a little to reduce.

10. Ladle into bowls, sprinkle chopped fresh parsley if you want, and serve with crusty bread or crackers for dipping.

9. Ladle and soup bowls (for serving)

FAQ

Crockpot Potato Broccoli Cheddar Soup Recipe Substitutions and Variations

• Potatoes: swap with diced sweet potatoes for a sweeter, earthier soup, or use cauliflower florets for a lower carb, creamier texture once blended.
• Broccoli: frozen broccoli works fine and saves time, or substitute chopped kale or spinach for a different green and a bit more bite.
• Whole milk + heavy cream: use half and half for a lighter finish, or 1 can evaporated milk plus a splash of water for similar creaminess without as much fat.
• Sharp cheddar: use Colby Jack or Monterey Jack for milder meltiness, or try Gruyere for a nuttier, richer flavor if you want to fancy it up.

Pro Tips

– Don’t skip fresh shredding on the cheese. Pre-shredded stuff has anti-caking agents that can make the soup a bit grainy, so grate a block of sharp cheddar right before you add it. Also add the cheese off the heat and stir slowly so it melts smooth and doesnt seize up.

– If your potatoes end up too firm, slice a few thinner instead of all big cubes at the start; they’ll cook faster and more evenly in the crockpot. Or if it’s already late in cooking, just cut a couple pieces open with a fork and drop them in smaller chunks to catch up.

– Mash about a third of the potatoes right in the crockpot like the recipe says, but leave some bigger chunks for texture. Use the back of a large spoon if you dont have a masher; it’ll still thicken the broth naturally without needing extra flour or starch.

– To keep the broccoli bright green and not mushy, add it near the end and check it a few minutes early. If you like a little bite, pull the cover off and test at 20 minutes; it keeps cooking in the residual heat even after you turn the slow cooker off.
