Step‑by‑Step Instructions for Keto Cauliflower & Hamburger Soup
Step 1: Brown the Beef
Heat a large skillet or Dutch oven over medium heat. Add the ground beef and cook for 5-7 minutes, stirring occasionally, until the meat is fully browned and no longer pink. This step establishes the savory base for your Keto Cauliflower & Hamburger Soup.
Step 2: Sauté the Aromatics
Add the chopped onions and minced garlic to the skillet with the cooked beef. Sauté for about 3-4 minutes, until the onions become translucent and the garlic releases a fragrant aroma. This combination will deepen the flavor of your soup.
Step 3: Incorporate the Cauliflower and Liquids
Mix in the cauliflower florets, tomato sauce, and beef broth. Bring the mixture to a gentle boil over medium-high heat, allowing the ingredients to meld for about 5 minutes. The vibrant colors should invite you as the soup begins to come together.
Step 4: Simmer Until Tender
Once boiling, reduce the heat to low and cover the pot. Let it simmer for 20 minutes, stirring occasionally, until the cauliflower is tender yet still holds its shape. This step is crucial for maintaining the texture in your Keto Cauliflower & Hamburger Soup.
Step 5: Add Cream for Richness
Stir in the heavy cream or cream cheese until completely blended. Allow the soup to heat through on low for an additional 3-5 minutes. You should see the soup turn creamy and rich, creating a comforting finish to your dish.
Step 6: Season to Perfection
Add Worcestershire sauce, salt, and pepper to taste. Stir well, adjusting the seasoning as necessary to bring out the flavors of the soup. This final touch ensures every spoonful of your Keto Cauliflower & Hamburger Soup is packed with savory goodness.
Step 7: Serve and Garnish
Ladle the hot soup into bowls and garnish with fresh parsley and an optional swirl of cream. The vibrant parsley adds a pop of color, making your comforting bowl of Keto Cauliflower & Hamburger Soup even more inviting for everyone at the table.

Keto Cauliflower & Hamburger Soup Recipe FAQs
What kind of cauliflower should I use for the soup?
Absolutely! Fresh cauliflower florets work best to achieve the ideal texture and flavor. Look for heads that are firm, with tightly packed florets and no dark spots. If you're in a pinch, frozen cauliflower can be a convenient substitute—just be sure to thaw and drain it before adding to your soup.
How long can I store Keto Cauliflower & Hamburger Soup in the fridge?
You can store your delicious soup in airtight containers in the fridge for up to 3 days. To keep it fresh, allow it to cool completely before sealing the container. Adding a piece of parchment paper between the lid and soup can help with moisture, ensuring your soup stays perfect until it's time to enjoy it again!
Can I freeze Keto Cauliflower & Hamburger Soup?
Certainly! Freezing is a great way to save leftovers. Portion the soup into freezer-safe containers, leaving about an inch of space at the top for expansion during freezing. It can be stored for up to 2 months. To thaw, just place it in the fridge overnight or use the defrost setting on your microwave, and then reheat on the stove with a splash of broth to bring back that creamy goodness.
What if my soup is too thick after cooking?
Very! If your soup turns out thicker than you'd like, simply stir in a bit of extra beef broth or water until you reach your desired consistency. This can bring back that comforting creaminess while still retaining the delicious flavors. Just make sure to warm it gently on the stove while you add the liquid.
Can I make this soup dairy-free?
Absolutely! For a dairy-free version of the Keto Cauliflower & Hamburger Soup, substitute heavy cream with coconut cream or cashew cream. These alternatives will provide a delightful creaminess without dairy. If using cream cheese, you can replace it with pureed silken tofu or a dairy-free cream cheese spread.
Is this soup suitable for kids or those with dietary restrictions?
Yes! The Keto Cauliflower & Hamburger Soup is not only a hit with kids and adults alike, but it's also a wonderful option for those following low-carb or keto diets.
