Ingredients

Scale
  • 1 tablespoon olive oil
  • 2 tablespoons butter
  • 1 medium yellow onion, chopped
  • 2 carrots, peeled and diced
  • 4 cups fresh broccoli florets
  • 4 cups chicken or vegetable broth
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon salt
  • 1/4 cup all-purpose flour
  • 2 cups milk (whole milk preferred for richness)
  • 3 cups sharp cheddar cheese, shredded
  • 1/2 cup heavy cream (optional, for extra creaminess)

Instructions

  1. Heat olive oil and butter in a large pot or Dutch oven over medium heat. Add the chopped onion and diced carrots. Cook until the onion softens, about 5 minutes.
  2. Add the broccoli florets, broth, garlic powder, salt, and pepper to the pot. Bring the mixture to a simmer, then cover and cook for 10 minutes, or until the broccoli is tender.
  3. In a small bowl, whisk the flour into the milk until no lumps remain. This creates a slurry.
  4. Slowly pour the milk mixture into the simmering soup, stirring constantly. Continue to cook, stirring often, until the soup thickens slightly, about 5 to 7 minutes. Do not let it boil rapidly.
  5. Reduce the heat to low. Stir in the shredded cheddar cheese one handful at a time, allowing each addition to melt completely before adding more. Stir until the cheese sauce is smooth and velvety.
  6. If using, stir in the heavy cream for added richness. Taste and adjust salt and pepper as needed.
  7. Serve the soup hot. You can leave it slightly chunky or use an immersion blender to make it smoother.

Notes

  • For a high-protein version, add 1/2 cup of cooked, shredded chicken breast when adding the cheese.
  • Use freshly shredded sharp cheddar cheese for the best melting quality and flavor. Pre-shredded cheese often contains anti-caking agents that prevent smooth melting.
  • If you prefer a chunkier soup, add half of the broccoli during the initial simmer and the other half during the last 5 minutes of cooking.
