What You’ll Need

Ingredients:

  • 4 cups potatoes, peeled and diced
  • 2 cups broccoli florets (fresh or frozen)
  • 1 small onion, finely chopped
  • 2 carrots, diced
  • 4 cups chicken or vegetable broth
  • 1 cup heavy cream
  • 2 cups shredded sharp cheddar cheese

Pro Tips

  1. Cut veggies evenly: This helps everything cook at the same rate, so you don’t end up with mushy broccoli or hard potatoes.
  2. Use sharp cheddar: It gives the soup a richer, more flavorful cheese taste. Mild cheddar works but won’t be as bold.
  3. Thicken with flour properly: Whisk the flour and butter into a paste (a roux) before adding it to the soup to avoid lumps.
  4. Blend to your liking: Use an immersion blender for a creamy soup or leave it chunky—your call!
  5. Make it kid-friendly: If your kids are picky, blend the broccoli into the soup so it’s smooth and hidden!

Tools You’ll Need

  • A crockpot (slow cooker)
  • Immersion blender or potato masher (optional, for blending)
  • Cutting board and sharp knife
  • Measuring cups and spoons
  • Small saucepan (for the roux)

Substitutions and Variations

  • Cheese: Swap cheddar for Gouda, Monterey Jack, or even a mix of cheeses.
  • Broccoli: Cauliflower is a great substitute or mix-in.
  • Cream: Use whole milk, half-and-half, or dairy-free alternatives like coconut milk.
  • Vegetarian: Stick with veggie broth instead of chicken broth.

Make-Ahead Tips

  • Prep veggies ahead: Chop potatoes, broccoli, carrots, and onions the night before and store them in the fridge.
  • Reheat and serve: This soup reheats beautifully on the stovetop or microwave—just add a splash of broth or milk if it gets too thick.
