What Italian Sausage did I use did I use for this Soup?

I used my favorite Turkey Italian Sausage for this soup that’s an updated version of a soup that was back in the archives of the blog, and I like the hot version of Italian Sausage that’s a bit spicy. But use pork Italian Sausage if you prefer, or if you can’t find turkey sausage. And you might want to switch it out for Sweet Italian Sausage without the added spiciness if you’re making the soup for kids

How to make Instant Pot Italian Sausage Soup a lower-carb soup?

For a version of this soup that’s much lower in carbs, just switch out the chickpeas for a 10 oz. or 12 0z. package of frozen cauliflower rice.

What Size Instant Pot Did I Use?

I use a 6 Quart Instant Pot (affiliate link) for all my Instant Pot Recipes. Check out my growing collection of Instant Pot Recipes! Or find more Instant Pot Recipes on my Slow Cooker or Pressure Cooker site.

Total Time 15 minutes

This easy Instant Pot Italian Sausage Soup is flavored with pesto, and this soup can also cook on the stove in less than an hour and it's delicious! Use garbanzo beans, or replace them with frozen cauliflower rice if you want fewer carbs.

Ingredients

  • 1 medium onion, chopped small
  • 1 green bell pepper, chopped small
  • 1 T olive oil, divided
  • 1 T minced garlic
  • 1 15 oz. can chickpeas (see notes)
  • 1 19.5 oz. pkg. Italian sausage (see notes)
  • 3 14 oz. cans chicken broth (see notes)
  • 1 14.5 oz. can petite diced tomatoes
  • 2 tsp. Italian Herb Blend
  • pinch of red pepper flakes (optional)
  • 1/4 cup basil pesto (see notes)

Instructions

  1. Chop the onion and green bell pepper.
  2. Heat 2 teaspoons olive oil in the Instant Pot on SAUTE, MEDIUM, and cook the onion and bell pepper 2-3 minutes or until barely starting to brown. Add minced garlic and cook 1 minute longer.
  3. While those aromatic ingredients cook, drain garbanzos into a colander placed in the sink and rinse with cold water. (You can mash them slightly with a potato masher (affiliate link) if you'd like smaller chunks of beans in the soup, but we didn't do that this time.)
  4. Push onions and peppers to the side, add the other teaspoon of olive oil, and crumble the Italian Sausage into the Instant Pot. Cook sausage, breaking apart with the turner, until sausage is nicely browned.
  5. Add the chicken broth, petite diced tomatoes, drained garbanzo beans (or frozen cauliflower rice), Italian Herb Seasoning (affiliate link), and a pinch of red pepper flakes (optional) to the Instant Pot.
  6. Lock lid and set Instant Pot to MANUAL, HIGH PRESSURE, 5 minutes.
  7. When cooking time is up, let pressure release naturally for 10-15 minutes, then release the rest of the pressure.
  8. Add the basil pesto and set the Instant Pot to SAUTE, LOW and cook about 5-1o minutes more to blend flavors.
  9. Serve hot, with Parmesan cheese to add at the table if desired.

STOVETOP DIRECTIONS:

  1. Heat olive oil in a large non-stick frying pan and saute the onion and green bell pepper.  Add garlic and cook about 1 minute more.
  2. Add the vegetables to soup pot with the chicken broth, petite diced tomatoes, Italian Herb Seasoning (affiliate link), and red pepper flakes (if using) start to simmer the soup over medium heat. (Use one more cup chicken stock for stovetop cooking.)
  3. Heat the other teaspoon of oil in the frying pan, squeeze the sausage out of the links, and brown the sausage, breaking apart with a turner as it cooks.
  4. While the sausage browns, rinse garbanzo beans as above, and mash if desired.
  5. Add the browned Italian sausage and drained beans (or frozen cauliflower rice) to the soup, turn heat to low, and simmer about 30 minutes. (Longer cooking time won’t hurt, even as long as a couple of hours.)
  6. After the soup has simmered enough to blend flavors. stir in the basil pesto and cook about 10 minutes more.
  7. Serve hot, with freshly-grated Parmesan cheese to add at the table if desired.

Notes

For a version of this soup with a lot less carbs, switch out the can of garbanzo beans for one 12 oz. package frozen cauliflower rice. Using cauliflower rice will lower the carbs to about 15 carbs per serving (and calories, fiber, sugar, and protein will also be slightly less.)

I used my favorite turkey Italian sausage, but use pork sausage if you prefer. You can use 5 cups homemade chicken stock if you prefer. Use one more cup chicken stock for stovetop cooking. I love using my frozen Basil Pesto with Lemon for this recipe, but I use my favorite purchased pesto when I don't have any in the freezer.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
If you’d like a soup with Italian sausage that’s lower in carbs, just replace the garbanzo beans in this recipe with a package of frozen cauliflower rice. I use lean turkey Italian Sausage and use a generous amount of sausage in proportion to the amount of beans to make this a low-glycemic soup that’s suitable for all phases of the original South Beach Diet.
