Ingredients

Scale

Main Ingredients

  • 1 lb Ground Beef (80/20 or leaner)
  • 1 medium Yellow Onion, diced
  • 3 cloves Garlic, minced
  • 4 cups Cauliflower Florets, cut into bite-sized pieces
  • 6 cups Beef Broth, low sodium
  • 1 (14.5 oz) can Canned Diced Tomatoes, undrained
  • 2 Tbsp Tomato Paste
  • 1 Tbsp Dried Italian Seasoning
  • 1 Bay Leaf, optional
  • 1 tsp Worcestershire Sauce
  • Salt and Freshly Ground Black Pepper, to taste

Optional Ingredients

  • 2 Tbsp Heavy Cream or Cream Cheese
  • Chopped Fresh Parsley, for garnish

Instructions

  1. Preheat Your Equipment: Heat a large skillet or Dutch oven over medium heat to prepare for browning the beef and cooking the soup evenly.
  2. Brown the Beef and Sauté Aromatics: Add ground beef to the heated pan and cook thoroughly until browned. Stir in diced onion and minced garlic, cooking until fragrant and the onions are translucent.
  3. Prepare Your Cooking Vessel: Use a Dutch oven or large pot that has enough capacity for simmering the soup, ensuring even cooking of the ingredients.
  4. Add Soup Ingredients: To the pot, add cauliflower florets, beef broth, canned diced tomatoes with their juice, tomato paste, dried Italian seasoning, bay leaf (if using), Worcestershire sauce, salt, and freshly ground black pepper. Stir well to combine all ingredients.
  5. Simmer the Soup: Bring the mixture to a gentle simmer, maintaining a low boil for 20–25 minutes, or until the cauliflower is tender and all the flavors have melded together beautifully.
  6. Add Cream and Final Seasoning: Stir in heavy cream or cream cheese if using to add richness and creaminess. Remove the bay leaf from the pot, taste the soup, and adjust the seasoning with additional salt and pepper if necessary.
  7. Serve and Garnish: Ladle the hot soup into bowls and garnish with chopped fresh parsley for a burst of color and freshness before serving.

Notes

  • If you prefer a thicker soup, you can mash some of the cauliflower florets before adding the cream.
  • The heavy cream or cream cheese is optional but adds a nice richness and smooth texture to the soup.
  • Use leaner ground beef for a lower fat option.
  • Adjust seasoning to taste, especially the Worcestershire sauce, which adds depth and umami.
  • This soup can be stored in the refrigerator for up to 4 days and freezes well for up to 3 months.
