  • 2 tablespoons butter
  • 4 ounces yellow onion chopped
  • 2 cloves garlic crushed
  • 1 tablespoon white wine vinegar
  • 4 ounces cream cheese cut into large chunks
  • 2 cups heavy cream
  • 3 cups low-salt chicken bone broth (low salt chicken or vegetables stock will work)
  • 2 teaspoons whole grain mustard
  • 1/4 teaspoon crushed red pepper flakes
  • 1 teaspoon Worcestershire sauce gluten-free
  • 1 pound broccoli florets fresh or frozen
  • 6 ounces sharp cheddar cheese shredded
  • 1 1/2 teaspoon sea salt (or to taste)
  • 1/4 teaspoon black pepper freshly ground


  1. Heat a large, heavy pot over medium heat. Add butter and stir to melt. When butter stops foaming, add the onions.

  2. Cook onions, stirring frequently until onions begin to appear translucent and start to brown on the edges. Stir in the garlic. Cook for one minute. 

  3. Stir in the vinegar and simmer, scraping up browned bits on the bottom of the pot. Simmer until the vinegar has almost completely evaporated. Stir in the cream cheese and about 1/2 cup of the heavy whipping cream.

  4. After the cream cheese melts, stir in the remaining heavy cream, prepared mustard, Worcestershire sauce, and crushed red pepper flakes. 

  5. Stir in the broth and bring the mixture to a simmer. Add the broccoli and return to a simmer. Simmer, stirring occasionally, until the broccoli is very tender-about 10-12 minutes.
