Before I tell you about this delicious Italian Sausage Stew and how you can make it in the Instant Pot or the Slow Cooker, I want to say a few words about how food blogging has changed. For sure when I started sharing recipes I never imagined there’d be a time when blogging became so competitive, search engines were so finicky about what was acceptable, and new cooking gadgets made previously-loved recipes no longer appealing. And then I switched to more carb-conscious eating, so the way I was cooking changed too.

I’m doing my best to manage so much change! I’m trying to update slow cooker recipes to have an Instant Pot option and trying to make lower-carb versions of recipes I used to make when I ate more carbs. But the changes come so quickly I’ll never be able to update every older recipe. If you had an old favorite on the site that you can’t find any more, please e-mail me; I have those older recipes and will be happy to send it to you! And today I am updating this crockpot stew that originally had Italian Sausage, red and green pepper, and Cannellini beans. (You can find the original version here if you’re curious.)

Of course now many people would make this in the Instant Pot and wouldn’t want the beans. Kara and I used more Italian Sausage, switched out the beans for mushrooms, and added some Rao’s Pasta Sauce to thicken and flavor the stew. And it was such a success! Whether or not you ever tried the original version, I hope you’ll try this tasty stew that’s so good eaten with Parmesan cheese sprinkled on top!

What ingredients do you need?

What kind of Italian Sausage did we use?

For months I haven’t been able to find my favorite turkey Italian sausage, so when I saw these one-pound rolls made by the same company I grabbed a bunch for the freezer. If you have turkey sausage links, just squeeze the sausage out. You can use pork Italian sausage, but it will add quite a bit of fat to the stew.

What kind of mushrooms did we use?

We used brown Cremini mushrooms for this recipe, but any mushrooms you have will be fine.

What Instant Pot and Slow Cooker Did I Use?

I originally used a 5-Quart Slow Cooker (affiliate link) for this recipe. I use a 6 Quart Instant Pot (affiliate link) for all my Instant Pot Recipes! You can find more Instant Pot Recipes on my other site, Slow Cooker or Pressure Cooker.

How to make Italian Sausage Stew:

(Scroll down for complete recipe with nutritional information; check the recipe notes for the slow cooker instructions and changes.)

  1. Chop onions into pieces about 1/2 inch.
  2. Heat one tablespoon olive oil in the Instant Pot on SAUTE, MEDIUM HEAT.
  3. Add onions and cook until they’re starting to soften and brown. Then add dried basil, Greek oregano, ground fennel, Spike Seasoning and black pepper and cook a few minutes longer.
  4. I was excited to find these one-pound rolls of turkey Italian sausage. If you have sausage in links, just squeeze it out of the casings.
  5. Add a little more olive oil to the Instant Pot and cook the Italian Sausage until it’s well-browned and most of the liquid has evaporated. 
  6. I used this Meat Chopper (affiliate link) to chop up the sausage while it cooked. (My new favorite cooking gadget!)
  7. While sausage cooks chop mushrooms and red and green bell peppers. 
  8. When sausage is nicely browned add mushrooms, red bell pepper, green bell pepper, Rao’s Pasta Sauce, and chicken broth to the Instant Pot. 
  9. Set Instant Pot to MANUAL, HIGH HEAT, 5 minutes.
  10. After the cooking time ends, let the stew natural release for 5 minutes.
  11. That’s it! Serve hot with some freshly-grated Parmesan to sprinkle on at the table if desired.

Prep Time 30 minutes
Cook Time 4 hours
Total Time 4 hours 30 minutes

Make this Italian Sausage Stew in the Instant Pot or the Slow Cooker; it will be delicious either way!

Ingredients

  • 12 oz. mushrooms
  • 1 medium onion
  • 1 red bell pepper
  • 1 green bell pepper
  • 1 T + 1 tsp. Olive Oil
  • 1 tsp. dried basil
  • 1 tsp. Greek oregano
  • 1 tsp. ground fennel
  • 2 tsp. Spike Seasoning (see notes)
  • ground pepper to taste
  • 2 lbs. turkey Italian Sausage
  • one 14 oz. can petite dice tomatoes
  • 2 cups Rao's Pasta Sauce
  • one 14 oz. can chicken broth
  • freshly grated parmesan cheese for serving (optional)

Instructions

  1. Chop onions into pieces about 1/2 inch or slightly larger.
  2. Heat one tablespoon olive oil in the Instant Pot on SAUTE, MEDIUM HEAT.
  3. Add onions and cook until they're starting to soften and brown. Then add dried basil, Greek oregano, ground fennel, Spike Seasoning and black pepper and cook a few minutes longer.
  4. Add a little more olive oil to the Instant Pot and cook the Italian Sausage until it's well-browned and most of the liquid has evaporated. Break the sausage apart as it cooks. (Don't rush this step. The browning adds flavor.)
  5. While sausage cooks chop mushrooms and red and green bell peppers. We made the peppers just slightly over 1/2 inch square and chopped the mushrooms into thick half-slices.
  6. When sausage is nicely browned add mushrooms, red bell pepper, green bell pepper, Rao's Pasta Sauce, and chicken broth to the Instant Pot. 
  7. Set Instant Pot to MANUAL, HIGH HEAT, 5 minutes.
  8. After the cooking time ends, let the stew natural release for 5 minutes.
  9. That's it! Serve hot with some freshly-grated Parmesan to sprinkle on at the table if desired.

Notes

SLOW COOKER INSTRUCTIONS:

--I would use just 1 1/4 cup of chicken broth for the slow cooker recipe.

--You can add the onion, red bell pepper, green bell pepper, and chopped mushrooms to the slow cooker without pre-cooking if you prefer. If you do they will release some water; I would reduce the amount of chicken broth to one cup. (The instructions below call for pre-cooking them, which is how I made it when I used the slow cooker.)

--Cook chopped onion, chopped red bell pepper, and chopped green bell pepper in olive oil until they are starting to soften, then add to slow cooker.

--Cook mushrooms until they release their liquid and are partly done, then add to slow cooker.

--Brown the Italian in the same pan, adding a bit more olive oil if needed, then add sausage to slow cooker.

--Add petite diced tomatoes, dried basil, dried oregano, ground fennel, and black pepper to slow cooker.

--Pour the broth over the other ingredients, add Rao's Pasta Sauce, and stir to combine. Cook on high for about 3 hours or on low for 6-8 hours.

--Serve hot, with plenty of parmesan cheese to sprinkle over at the table.

If you don't have Spike Seasoning, use any all-purpose seasoning blend.

You can use turkey or pork Italian Sausage (either hot or mild) but the pork Italian sausage will definitely make the stew higher in fat.

If you don't have Rao's Pasta Sauce, choose the pasta sauce with the lowest amount of sugar you can find.
