Ingredients

  • 1 tablespoon olive oil
  • 8 oz mushrooms, diced
  • 1 teaspoon paprika
  • 1 teaspoon fennel seed
  • ½ teaspoon pepper flakes
  • ½ teaspoon Italian seasoning
  • 1 tablespoon Better than Bouillon**
  • ½ cup green beans, chopped
  • ½ cup celery, diced leaves and all
  • 1 cup diced tomatoes
  • ½ cup carrots, sliced
  • ½ cup sweet bell peppers, diced
  • 3 tablespoons tomato paste
  • ½ cup zucchini or yellow squash, sliced
  • 1 cup cabbage, chopped
  • 1 cup broccoli florets
  • 8 cups water
  • ¼ cup Parmesan cheese, grated
  • 2 cloves garlic, crushed

Instructions

  1. In a large soup pot, add the oil and heat to medium high. 

  2. Add in the mushrooms and all the spices except the garlic. Mix well and let the mushrooms cook for a few minutes until they are almost cooked.

  3. Add in the rest of the vegetables, tomato paste, Better than Boullion and water. Mix well and bring to a boil. Then turn down the heat to let it simmer for 20 minutes.

  4. Now you want to add in the Parmesan cheese and crushed garlic. Mix well and let it simmer for 5 minutes more and you are done. You can always season with salt and black pepper if you wish but I didn't think it needed it.

  5. You can freeze this soup and just reheat on the stove or in the microwave.

  6. **You can use vegetable Better than Bouillon if you want to keep this vegetarian or you can use chicken or beef. All will work well in this recipe. If you don't have better than bouillon, use regular bouillon but I highly recommend the Better than Bouillon products because they add so much flavor. 

  7. To make this in the Instant Pot

    Just add the oil mushrooms and spices and saute them in the Instant Pot for a few minutes. Turn off the saute function and place the rest of the ingredients in. Mix well and then secure the lid. Manually cook for 8 minutes and when done, immediately release the pressure. That's it!
