Ingredients

Scale

Meats and Oils

  • 1 tbsp vegetable oil (or olive oil, not extra virgin, or coconut oil)
  • 1 lb Italian sausage, ground
  • ½ lb lean ground beef

Vegetables and Aromatics

  • 1 medium white onion, chopped
  • 6 cloves garlic, minced

Tomato and Broth

  • 2 tbsp tomato paste
  • 1 (14 oz) can crushed tomatoes
  • 2 cups tomato passata (or more crushed tomatoes or tomato sauce with water)
  • 2½ cups low sodium chicken broth (or beef or vegetable broth)

Spices and Herbs

  • 1 tsp fennel seeds
  • 2 tsp Italian seasoning
  • 2 tsp onion powder
  • 1½ tsp sea salt
  • ½ tsp black pepper

Cheeses

  • 8 oz shredded mozzarella cheese (can substitute cheddar or asiago or a combination)
  • ½ cup grated Parmesan cheese (or nutritional yeast for plant-based option)

Fresh Garnish

  • ½ cup fresh parsley, chopped (or fresh basil or cilantro)
  • Additional grated Parmesan and chopped parsley for garnish

Instructions

  1. Heat and Cook Meats: Grab a large pot and heat it over medium-high heat. Add the vegetable oil, Italian sausage, ground beef, and chopped white onion. Break the ground meat apart and cook it until it browns, which should take about 7-8 minutes.
  2. Add Garlic: Stir in the minced garlic and cook for another minute to release its aroma and flavor.
  3. Add Tomato Ingredients and Broth: Mix in the tomato paste, crushed tomatoes, tomato passata, and chicken broth. These ingredients create a rich tomato base for your soup.
  4. Season the Soup: Add fennel seeds, Italian seasoning, onion powder, sea salt, and black pepper. Stir well to combine all the flavors.
  5. Simmer the Soup: Bring the soup to a boil, then lower the heat and let it simmer gently for around 20 minutes. This allows the flavors to meld together and the soup to thicken slightly.
  6. Add Cheese and Herbs: Stir in the shredded mozzarella and grated Parmesan cheese, as well as the fresh chopped parsley. This adds creaminess and freshness to your soup.
  7. Serve and Garnish: Ladle the soup into bowls and garnish with additional grated Parmesan and chopped parsley for an appealing presentation and extra flavor.

Notes

  • You can substitute Italian sausage with plant-based sausages or other sausage types for different flavor profiles.
  • Ground turkey, chicken, or plant-based ground meat or tofu can replace the ground beef as a leaner or vegetarian protein option.
  • If you don’t have fresh garlic, use garlic powder or minced garlic in oil to save time.
  • Tomato passata can be replaced by extra crushed tomatoes or tomato sauce mixed with a little water.
  • Use low sodium broth to better control salt levels and dietary preferences.
  • For a plant-based version, replace cheese with nutritional yeast and substitute meats accordingly.
  • Fennel seeds add a subtle anise flavor, but they can be omitted if preferred.
  • Use fresh herbs like basil or cilantro if parsley is unavailable for garnish.
