  • 1 lb Italian sausage (mild or spicy)
  • 1 small yellow onion, diced
  • 3 garlic cloves, minced
  • 4 cups chicken broth
  • 1 can (14.5 oz) diced tomatoes

Pro Tips

  1. Brown the sausage first. It adds a ton of flavor and keeps the soup from getting greasy.
  2. Don’t overcook the tortellini. Add it in during the last 30 minutes so it stays perfectly tender.
  3. Want it thicker? Mash a few tortellini or add a cornstarch slurry (1 tbsp cornstarch + 1 tbsp water).
  4. Make it kid-friendly. Skip the red pepper flakes if your little ones don’t like spice.
  5. Serve with crusty bread! It’s perfect for soaking up all that creamy broth.

Tools Needed

  • Large skillet
  • Slow cooker
  • Wooden spoon
  • Measuring cups and spoons
  • Ladle

Substitutions & Variations

  • Vegetarian: Swap the sausage for sautéed mushrooms and use veggie broth.
  • Low-carb: Use zucchini noodles instead of tortellini.
  • Different greens: Kale or Swiss chard work great in place of spinach.
  • Lighter version: Replace heavy cream with half-and-half or evaporated milk.

Make-Ahead Tips

  • Prep everything the night before: brown the sausage, chop the onion, and mince the garlic. Store in the fridge, then toss everything into the slow cooker in the morning.
  • The soup (without tortellini and spinach) can be made 1 day ahead. Just reheat, add tortellini and spinach, and cook until tender.

Instructions

1. Brown the sausage and sauté the aromatics

Heat a skillet over medium heat. Brown the Italian sausage, breaking it into crumbles, until fully cooked. Add the diced onion and garlic, cooking for 2-3 minutes until softened. Drain any excess grease.

2. Combine ingredients in the slow cooker

Add the sausage mixture to your slow cooker. Stir in chicken broth, diced tomatoes, basil, oregano, red pepper flakes, salt, and black pepper. Cover and cook on low for 4-6 hours or high for 2-3 hours.

3. Add tortellini and spinach

About 30 minutes before serving, stir in the cheese tortellini and fresh spinach. Cover and cook until the tortellini is tender and the spinach is wilted.

4. Finish with cream and Parmesan

Once the tortellini is tender and the spinach has wilted, stir in the heavy cream and grated Parmesan. Mix well until the soup turns rich and creamy. Taste and adjust seasoning if needed. Ladle the soup into bowls, top with extra Parmesan and cracked black pepper, and serve hot with crusty bread on the side. Enjoy!
