Ingredients

  • 1 lb Italian sausage
  • 3 tbsp butter
  • 1/2 onion
  • 2 garlic cloves
  • 8 oz chopped radishes peeled and chopped
  • 1/4 cup chopped grape tomatoes
  • 8 oz mushrooms sliced
  • 5 cups chicken broth
  • 2 cups heavy whipping cream
  • 1 tsp basil
  • 1 tsp parsley
  • 1 tsp salt
  • 1/2 tsp pepper
  • 3/4 cup sharp cheese
  • 4 oz baby spinach
  • 1/2 cup crumbled, cooked bacon

Instructions

  • In a dutch oven, brown Italian sausage in larger chunks then drain and set aside.
  • In the same dutch oven, add 3 Tb butter, garlic, onion, mushrooms and tomatoes, and radishes. Sauté for 7 minutes.
  • Add about ¼ cup of the chicken broth to the pot then deglaze using a wooden spoon to scrape brown bits from the bottom. All the bits that are stuck to the bottom of your pot are flavorful, so don't discard these!
  • Add the rest of the chicken broth and seasoning, then bring to a boil.
  • Reduce to medium heat and cook for approx 20-30 minutes with the lid on or until the radishes are tender. Stoves cook differently, so you may need to adjust your cooking time.
  • Add sausage, heavy whipping cream, and 4 oz spinach to your pot and simmer on low with the lid on for approx 10 minutes.
  • Add 3/4 cup cheese and 1/2 cup crumbled bacon. Stir until the cheese melts.
  • Serve hot!

-Here are some substitutions you can try if you want to swap out an ingredient for something else:
  • Use hot Italian sausage if you like spicy foods
  • Use small cauliflower florets if you want a chunkier more "potato-like" soup
  • Puree cooked cauliflower and add it to your soup to thicken it (see notes below)
  • Swap out the pork sausage for ground chicken, turkey or beef
  • Feel free to use bone broth, beef broth or veggie broth instead
  • Add your own homemade Tuscan seasoning
  • Swap out the fresh tomatoes with sun-dried tomatoes
