Serving suggestion — your result will vary

Most broccoli cheddar soup leans on flour or a starchy roux to get thick. This one skips it — cream cheese and a heap of sharp cheddar do the body, so a bowl lands around 7g net carbs while tasting like the diner version. It comes together in one pot in about half an hour.

The one rule worth following: melt the cheese off the heat. Boiling shredded cheese is what turns a smooth soup grainy.

Ingredients

  • 4 tablespoons butter
  • 1/2 small onion, diced
  • 2 cloves garlic, minced
  • 4 cups chicken broth
  • 1 lb broccoli florets, chopped small
  • 1 cup heavy cream
  • 4 oz cream cheese
  • 3 cups shredded sharp cheddar
  • 1/2 teaspoon salt, 1/4 teaspoon pepper
  • Pinch of nutmeg (optional)

Steps

  1. Melt the butter in a large pot over medium. Cook the onion until soft, about 4 minutes, then add the garlic for 30 seconds.
  2. Pour in the broth and add the broccoli. Simmer until the broccoli is tender, 10–12 minutes.
  3. Lower the heat. Stir in the heavy cream and cream cheese until the cream cheese melts smoothly.
  4. Off the heat, add the cheddar a handful at a time, stirring until each addition melts before adding more (high heat will make it grainy).
  5. Season with salt, pepper, and nutmeg. For a thicker texture, blend half the soup and stir it back in.

Notes and swaps

Pre-shredded cheese is coated with anti-caking starch and melts less cleanly — shred a block yourself if you can. For a thicker bowl without flour, blend half the soup and stir it back in, or let it reduce a few extra minutes. Add cooked bacon or shredded rotisserie chicken to turn it into a meal.
