Step-by-Step Instructions
Step 1: Prepare the Vegetables
Peel and dice the potatoes into bite-sized pieces.
Chop the broccoli into small florets.
Dice the onion, chop the celery, shred the carrots, and mince the garlic.
Step 2: Add Ingredients to the Crockpot
Place the potatoes, broccoli, onion, carrots, celery, and garlic into the slow cooker.
Pour in the chicken broth.
Add the salt, pepper, thyme, paprika, and onion powder.
Stir everything together.
Step 3: Slow Cook
Cover and cook:
- Low: 6–8 hours
- High: 3–4 hours
The vegetables should be very tender when finished.
Step 4: Make It Creamy
About 30 minutes before serving, add:
- Cream cheese
- Heavy cream
- Whole milk
- Butter
Stir until the cream cheese melts completely into the soup.
Step 5: Blend (Optional)
For a thicker, creamier soup:
- Mash some of the potatoes with a potato masher directly in the slow cooker, or
- Use an immersion blender to partially blend the soup while leaving some chunks for texture.
Step 6: Add the Cheese
Gradually stir in the freshly shredded cheddar cheese a handful at a time.
Mix until fully melted and smooth.
Avoid boiling the soup after adding the cheese, as high heat can cause it to separate.
Step 7: Taste and Adjust
Taste the soup and adjust the seasoning with additional salt and pepper if needed.
If the soup is thicker than desired, stir in a little extra broth or milk until it reaches your preferred consistency.
Step 8: Serve
Ladle the hot soup into bowls.
Top with extra cheddar cheese, crispy bacon, green onions, parsley, or croutons if desired.
Serve immediately with warm bread or biscuits.
Tips for the Best Soup
- Freshly shred your cheddar cheese for the smoothest melting texture.
- Use russet potatoes for a naturally creamy soup.
- Don’t overcook the broccoli if you prefer it to retain a little texture—add it during the last 1–2 hours of cooking on Low if desired.
- Stir the dairy ingredients in gently to maintain a silky consistency.
- Partially mashing the potatoes creates a naturally thick soup without adding flour.

Frequently Asked Questions
Can I use frozen broccoli?
Yes. Frozen broccoli works well and can be added during the last hour of cooking to prevent it from becoming too soft.
Why did my cheese become grainy?
Cheese can separate if it’s added when the soup is boiling or if pre-shredded cheese is used. Reduce the heat before adding cheese and use freshly grated cheddar for the smoothest results.
Can I make this soup thicker?
Yes. Mash some of the cooked potatoes directly in the slow cooker or blend a portion of the soup with an immersion blender. You can also stir in a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water) during the last 20–30 minutes if needed.
Can I prepare the ingredients the night before?
Absolutely. Chop the vegetables and store them in the refrigerator overnight. In the morning, simply add everything to the slow cooker and start cooking.
What potatoes work best?
Russet potatoes create the creamiest texture because of their higher starch content, while Yukon Gold potatoes provide a buttery flavor and hold their shape a bit better.
