Add Ingredients to Crockpot:
In the crockpot, add the broccoli florets, diced potatoes, chopped onion, minced garlic, broth, thyme, salt, and pepper.
Cook the Soup Base:
Cover and cook on Low for 6–7 hours or on High for 3–4 hours, until the potatoes and broccoli are tender.
Blend the Soup (Optional):
Use an immersion blender to blend the soup to your desired consistency—smooth or slightly chunky. Alternatively, transfer half of the soup to a blender, blend until smooth, and return it to the crockpot for a thicker texture.
Add Cream and Cheese:
Stir in the heavy cream or milk and shredded cheddar cheese. Continue to cook on Low for 10–15 minutes, stirring occasionally, until the cheese is melted and the soup is creamy.
Serve and Garnish:
Ladle the soup into bowls and garnish with chopped chives or parsley, if desired.
Enjoy this warm and comforting potato broccoli cheddar soup, perfect for chilly days!
