Equipment

  • Skillet
  • Slow Cooker

Ingredients

  • 8 tablespoons butter
  • 3 teaspoons jarred minced garlic
  • 1 teaspoon dried rubbed sage
  • 1/4 teaspoon salt
  • 1 pound boneless skinless chicken thighs
  • 15 oz can diced tomatoes with green chilies
  • 2 1/2 cups chicken broth
  • 1 cup heavy cream
  • 12 oz spaghetti noodles
  • ½ cup shredded parmesan cheese

Instructions

  • Heat skillet to medium-high heat
  • Cut butter into 1 tablespoon pieces and add to skillet
  • Let butter melt until it starts to bubble, then whisk
  • Add garlic, sage, and salt to butter; continue whisking until the bubbles dissipate and the butter starts to develop brown specks and takes on a nutty aroma
  • Remove skillet from heat and continue to whisk for 1-2 more minutes while it cools
  • Add butter to slow cooker along with chicken breasts, broth, and can of diced tomatoes and chilies
  • Cover and cook on low for 6-8 hours or high for 3-4 hours until chicken is fully cooked
  • Remove chicken from the slow cooker and shred with two forks
  • Add heavy cream, spaghetti noodles, and parmesan cheese to slow cooker and press the noodles into the liquid until fully covered and they start to soften
  • Return chicken to the slow cooker and give everything a stir to combine
  • Turn slow cooker to high and continue to cook for 30-40 minutes (stirring 2-3 times throughout) until pasta is cooked to al dente
  • Serve with an extra sprinkle of parmesan cheese and parsley or as desired

Notes

  • Store leftovers in the fridge for up to 3 days and reheat in the microwave.
  • If noodles are not completely cooked or too dry at the end, add a little more broth and continue cooking while stirring occasionally.
  • If there is too much sauce, you can thicken it by making a slurry of 1 tablespoon cornstarch and 1 tablespoon of water. Stir it into the slow cooker mixture and let it heat through.
  • To make this recipe gluten-free, use gluten-free spaghetti noodles and reduce the broth by ¼ cup. Cooking time may be slightly less, so monitor in the last 30-60 minutes.
