Prep Time 10 minutes
Cook Time 6 hours
Servings 6

Ingredients

  • 1 lb fresh broccoli florets chopped into small pieces
  • 1 medium yellow onion finely diced
  • 2 cloves garlic minced
  • 4 cups low-sodium chicken or vegetable broth
  • 1/2 teaspoon dried thyme
  • 1/4 teaspoon ground nutmeg
  • Salt and black pepper to taste
  • 1 cup heavy cream or half-and-half
  • 2 cups shredded sharp cheddar cheese
  • 2 tablespoons cornstarch mixed with 2 tablespoons cold water slurry

Instructions

  1. Place the chopped broccoli, diced onion, minced garlic, broth, thyme, and nutmeg into the slow cooker. Season with a pinch of salt and pepper.
  2. Cover and cook on low for 4 to 6 hours or on high for 2 to 3 hours, until the broccoli is very tender.
  3. Once the broccoli is soft, use an immersion blender to blend the soup directly in the slow cooker until it reaches your desired consistency.
  4. You can blend it until completely smooth or leave a few small chunks of broccoli for texture.
  5. If you do not have an immersion blender, carefully transfer the soup in batches to a standard blender and return it to the slow cooker.
  6. Stir in the cornstarch slurry, heavy cream, and shredded cheddar cheese.
  7. Cover the slow cooker and cook on high for an additional 20 to 30 minutes. This allows the soup to thicken and the cheese to melt completely into the base.
  8. Give the soup a final stir, taste for seasoning, and add more salt or pepper if needed. Serve warm with crusty bread or crackers.
  9. Add crunch and color to each bowl with simple toppings. Try toasted pumpkin seeds or chopped walnuts for texture; sprinkle them just before serving so they stay crisp.
  10. For extra flavor, grate sharp cheddar or crumble feta over the hot soup. The cheese will melt slightly and add savory depth.
  11. Fresh herbs lift the dish: chop parsley, chives, or dill and scatter a teaspoon or two per bowl. A small drizzle of olive oil or a light swirl of crème fraîche will add silkiness.
  12. If you want heat, add a few red pepper flakes or a dash of hot sauce. For a low-calorie option, lemon zest and cracked black pepper brighten the soup without extra fat.

Slow Cooker Tips

  1. Blend while the vegetables are hot for the smoothest texture; a high-speed blender gives the creamiest finish.
  2. For a partly chunky soup, reserve 1 cup of cooked broccoli, fold it in after blending, and heat through.
  3. Control thickness by adjusting liquid: add more broth to thin, or mash a cooked potato into the soup to thicken naturally. Add cream gradually and stir; overheating cream can separate, so warm it gently.
  4. If you want extra silkiness, mix 1–2 tablespoons of softened cream cheese into the hot soup until smooth. Finish with a splash of lemon juice to brighten flavors and a grind of black pepper for balance.
