Equipment

  • Slow Cooker

Ingredients

  • 1 pound chicken breast
  • 1 cup pesto
  • 8 cups chicken broth
  • 2 handfuls spinach about 2 cups, tightly packed
  • 7 oz short pasta like rotini or penne
  • ½ tsp salt

Instructions

  • Place the chicken breasts, pesto, and chicken broth into your slow cooker. Give it a quick stir to combine.
  • Cover and cook on low for 6–7 hours or high for 3–4 hours, until the chicken is fully cooked and tender.
  • Remove the chicken from the slow cooker and shred it using two forks. Return the shredded chicken back into the soup.
  • Stir in the uncooked short pasta (like rotini or penne). Cover and cook on high for 20–25 minutes, or until the pasta is tender.
  • Once the pasta is cooked, stir in the spinach and salt. Let it sit for another 5–10 minutes until the spinach wilts.
  • Taste and adjust seasoning if needed, then serve warm. Enjoy your creamy, cozy slow cooker chicken pesto soup!

Notes

  • Use rotisserie chicken for a quicker version, add it at the end instead of slow cooking.
  • Taste before serving since pesto and broth may already be salty.
  • Add spinach at the end so it stays fresh and perfectly wilted.
  • For a thicker soup, reduce broth slightly or add a splash of cream at the end.
