Ingredient Notes & Details

Potatoes
Use Yukon Gold or Russet potatoes for the best texture. Yukon Gold gives a naturally creamy consistency, while Russets break down more for a thicker soup.

Broccoli
Fresh broccoli works best for texture, but frozen can be used in a pinch. Just add it later to prevent overcooking.

Cheddar Cheese
Sharp cheddar gives the best flavor. Always shred your own cheese if possible—it melts smoother than pre-shredded varieties.

Onion
Adds depth and a subtle sweetness to the soup base. Yellow or white onions work well.

Garlic
Fresh garlic enhances the savory flavor. You can substitute with garlic powder if needed.

Chicken Broth
Provides a flavorful base. Vegetable broth works perfectly for a vegetarian version.

Heavy Cream
This is what gives the soup its rich, luxurious texture. Half-and-half can be used for a lighter option.

Butter
Adds richness and helps create that classic comforting flavor.

Flour
Used to slightly thicken the soup. You can skip it for a thinner consistency or use a cornstarch slurry.

Salt & Pepper
Essential for balancing flavors—adjust to taste at the end.

Step-by-Step Instructions

Step 1: Prep your ingredients
Peel and dice the potatoes into bite-sized chunks. Chop the broccoli into small florets and finely dice the onion.

Step 2: Add to the crockpot
Place the potatoes, broccoli (reserve half if you like more texture), onion, garlic, and chicken broth into your slow cooker.

Step 3: Cook low and slow
Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours. The potatoes should be fork-tender and easy to mash.

Step 4: Create the creamy base
About 30 minutes before serving, melt butter in a small saucepan. Whisk in the flour and cook for 1–2 minutes until lightly golden.

Step 5: Add cream and thicken
Slowly whisk in the heavy cream until smooth. Let it thicken slightly, then pour this mixture into the crockpot.

Step 6: Blend (optional)
For a smoother soup, use an immersion blender to partially blend the soup. Leave some chunks for texture.

Step 7: Stir in the cheese
Add the shredded cheddar cheese gradually, stirring until fully melted and smooth.

Step 8: Final seasoning
Taste and adjust salt and pepper as needed. Add remaining broccoli if you reserved some for texture.

Step 9: Serve warm
Ladle into bowls and enjoy immediately while hot and creamy.
