Ingredients
  

  • 1 –2 lbs ground turkey
  • 1 tsp baking soda optional
  • 1 onion chopped
  • 2 –3 cloves garlic
  • 3 tbsp Italian seasoning
  • 1 tsp red pepper flakes optional
  • 2 15 oz cans stewed tomatoes
  • 8 oz cream cheese cubed
  • 4 cups chicken broth
  • 3 –4 cups spinach
  • 1 package tortellini

Equipment

  • Cast iron skillet (for browning meat)
  • Slow Cooker

Method
 

  1. Prep the Turkey: Sprinkle baking soda over ground turkey (optional) and mix in. In a skillet, sauté onion, then garlic. Add turkey and cook until browned. Stir in Italian seasoning and red pepper flakes.
  2. Build the Soup Base: Transfer browned mixture to slow cooker. Add stewed tomatoes, cream cheese, and chicken broth. Stir to combine.
  3. Cook: Cook on low for 4-8 hours, stirring occasionally if possible to help the cream cheese melt fully.
  4. Add Spinach & Tortellini: About 15 minutes before serving, blend spinach (if desired) and stir into soup. Add fresh tortellini. *If using frozen or dried tortellini: add 25–30 minutes before serving.
  5. Finish & Serve: Stir gently, let everything heat through, and serve warm with sourdough bread.

Notes

Tips & Tricks

  • Blend the spinach – Perfect for picky eaters
  • Stir cream cheese occasionally – Helps it melt smoothly
  • Adjust thickness – Add more broth if it becomes too thick
  • Watch tortellini timing – Overcooking can make it too soft
  • Reheat smart – Add broth or water the next day as pasta absorbs liquid
  • Make it richer – Add a sprinkle of mozzarella or parmesan on top
