This Hearty Hamburger Cauliflower soup is a quick and easy meal that is low carb and keto-friendly. The soup is healthy, made in a savory broth, loaded with vegetables and lean meat, diced tomatoes and instead of potatoes, I used cauliflower! Delicious!
Ingredients for Hearty Hamburger Cauliflower soup.
- 2 Tablespoons olive oil or avocado oil (more if needed)
- ground beef, 1 lb.
- 1 medium onion, chopped
- 1 cup celery, chopped
- 2 medium carrots, chopped
- 1 can crushed tomatoes, 16 oz.
- 2 teaspoons minced garlic (minced garlic from a jar is fine for this)
- 1 teaspoon salt
- fresh ground black pepper to taste
- 2 teaspoons dried parsley
- 2 teaspoons dried thyme
- 1 teaspoon onion powder
- 2 tablespoons Worcestershire Sauce
- 4 cups beef broth
- 2 cups cauliflower florets (about half a medium head) can also use 2 cups frozen cauliflower rice
- 1-2 Tablespoons balsamic vinegar (or other flavorful vinegar of your choice)
- freshly-grated Parmesan cheese for serving (optional but recommended)
DIRECTIONS:
- Chop onion, celery and carrots and measure out 2 tsp minced garlic (or chop fresh garlic if you prefer.)
- Heat 1 tablespoon olive oil in the Instant Pot on SAUTE, HIGH HEAT, add the ground beef and cook until it’s browned (about 5 minutes), breaking apart with a wooden turner as it cooks. I used lean ground beef so I didn’t need to drain any fat but drain some fat from the pot if needed when the beef is browned.
- Season the browned meat with salt and fresh ground black pepper, push it over to the side, add another tablespoon of olive oil if needed, and add the chopped onion, celery and carrots. Cook 5 minutes, until softened, then add the minced garlic and cook a minute or two more. Mix the onion/celery mixture into the ground beef.
- Add the rest of the spices, Worcestershire Sauce, beef broth, canned tomatoes and cauliflower to the pot. Lock the lid and set the Instant Pot to MANUAL, HIGH PRESSURE, 6 minutes. After cooking time is up, let the pot natural release (about 10 minutes)
- Open the lid, give it few stirs (By now the cauliflower florets that you have added will be mostly dissolved, falling apart and thickening the soup.)
- Stir in 1-2 T balsamic vinegar (or any flavorful vinegar will work, and taste to see if you want more salt and/or fresh ground black pepper.
- Serve hot, with freshly grated Parmesan cheese if desired.
Recipe notes:
1. Carrots are higher carb veggies so the use of carrots is optional, especially if you’re a keto follower. I used 2 medium carrots for the entire soup. I’m a low carber, not a strict keto so for me few pieces of carrots is no problem.
2. For more hearty and carb loaded soup, you can add macaroni, pasta or potatoes and proceed cooking in Instant pot as per recipe. Kids tend to love this soup more with pasta and cheese.
3. Stove top version: proceed as per instructions above, then simmer for 20-30 minutes after adding all the ingredients until everything is cooked through and cauliflower is falling apart and dissolved.

Just made this soup and it is delicious. I added a few things from freezer, corn and green beans. A little elbow macaroni. I love it. Won’t tell family it has cauliflower in it. This is a keeper.
So glad you enjoyed ?. Thanks for your feedback
Very good. When I went to the fridge for my cauliflower I realized it was way past prime. So I subbed Potato chopped in 1 – 1 1/2″ pieces. A home made broth and good quality ground beef really help make it flavorful.
