Way back in the archives of this blog there’s a recipe called Ground Beef and Barley Soup that used to be one of my favorites when I wasn’t thinking so much about carbs, and that’s the recipe that inspired this Instant Pot Low-Carb Ground Beef Cauliflower Soup. Both recipes are the kind of simple soup you might make when you have ground beef thawed out in the fridge and just want some soup that’s warm and comforting, and this soup was so quick and easy to make in the Instant Pot.

The ground beef and cauliflower gets added flavor from celery, garlic, parsley, thyme, onion powder, Worcestershire sauce, and a splash of balsamic vinegar added at the end, and we used frozen cauliflower rice to make it easy. We enjoyed the Instant Pot Low-Carb Ground Beef Cauliflower Soup with a generous sprinkle of freshly-grated Parmesan cheese to add at the table, but you can certainly omit that if you want a dairy-free soup.

How to Make Instant Pot Low-Carb Ground Beef Cauliflower Soup:

(Scroll down for complete printable recipe, including nutritional information.)

1. Chop onion and celery and measure out 2 T minced garlic.
2. Heat olive oil in the Instant Pot (affiliate link) on SAUTE, HIGH HEAT, add ground beef and cook until it’s nicely browned, breaking apart with a plastic or wooden turner as it cooks.
3. When the meat is browned, drain excess fat if needed and season with salt and fresh ground black pepper.
4. Then push browned meat over to the side, add another teaspoon of olive oil if needed, and add the chopped onion and celery.
5. Cook 3-4 minutes, then add the Minced Garlic (affiliate link) and cook a minute or two more.
6. Mix the barely-cooked onion/celery mixture into the ground beef.
7. Add Dried Parsley (affiliate link), Dried Thyme (affiliate link), Onion Powder (affiliate link), Worcestershire Sauce (affiliate link), beef broth, vegetable broth, and 1 cup frozen cauliflower rice to the pot.
8. Lock the lid and set the Instant Pot to MANUAL, HIGH PRESSURE, 10 minutes. Let the pot natural release (or natural release 10 minutes and then release the rest of the pressure if you prefer.
9. Turn the IP settings back to SAUTE, MEDIUM HEAT, add two more cups cauliflower rice and let the soup simmer until the newly-added cauliflower rice is cooked, about 10-12 minutes. (By now the first cauliflower rice will be mostly dissolved, thickening the soup.)
10. 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.
11. Serve hot, with plenty of freshly-grated Parmesan cheese to add at the table!

Instant Pot Low-Carb Ground Beef Cauliflower Soup is an easy comforting soup with ground beef, and this uses ingredients you might already have on hand!

Ingredients

• 1 T olive oil (plus a little more if needed)
• 1 lb. ground beef
• 1 medium onion, chopped small
• 1 cup chopped celery
• 2 T minced garlic (minced garlic from a jar is fine for this)
• 1 tsp. kosher salt
• fresh-ground black pepper to taste
• 2 T dried parsley
• 2 tsp. dried thyme
• 1 tsp. onion powder
• 2 T Worcestershire Sauce (see notes for gluten-free)
• 3 cans (14 oz. size) beef broth
• 1 can (14 oz. size) vegetable broth
• 3 cups frozen cauliflower rice (divided)
• 2 T balsamic vinegar (or other flavorful vinegar of your choice)

Instructions

1. Chop one cup each of onion and celery and measure out 2 tablespoons minced garlic (or chop fresh garlic if you prefer.)
2. Heat 1 tablespoon olive oil in the Instant Pot (affiliate link) on SAUTE, HIGH HEAT, add the ground beef and cook until it's nicely browned, breaking apart with a plastic or wooden turner as it cooks. (Don't use a metal turner. which might scratch the pot.) 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.
3. Season the browned meat with salt and fresh ground black pepper, push it over to the side, add another teaspoon of olive oil if needed, and add the chopped onion and celery. Cook 3-4 minutes, then add the minced garlic and cook a minute or two more. Mix the barely-cooked onion/celery mixture into the ground beef.
4. Add dried parsley, dried thyme, onion powder, Worcestershire Sauce (affiliate link), beef broth, vegetable broth, and 1 cup frozen cauliflower rice to the pot. Lock the lid and set the Instant Pot to MANUAL, HIGH PRESSURE, 10 minutes. After cooking time is up, let the pot natural release (or natural release 10 minutes and then release the rest of the pressure if you want it to go a bit faster.)
5. Turn the IP settings back to SAUTE, MEDIUM HEAT, add two more cups cauliflower rice and let the soup simmer until the newly-added cauliflower rice is cooked, about 10-12 minutes. (By now the first cauliflower rice you added will be mostly dissolved, thickening the soup.)
6. Stir in 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.
7. Serve hot, with freshly-grated Parmesan cheese to add at the table if desired.

Notes

Use gluten-free Worcestershire Sauce (affiliate link) if needed.
