  • 1 can 10 oz diced tomatoes with green chilies
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • ½ tsp paprika

  • 1 tbsp butter
  • 4 oz cream cheese softened
  • ½ cup milk or heavy cream
  • 1 cup shredded cheddar cheese

Method
 

  1. Place the chicken breasts in the Instant Pot.
  2. Add chicken broth, diced tomatoes with green chilies, garlic powder, onion powder, paprika, salt, and black pepper.
  3. Close the lid and cook on High Pressure for 10 minutes.

  6. Turn the Instant Pot to Sauté mode and return the shredded chicken to the pot.
  7. Add the broken spaghetti and gently push it into the liquid.
  8. Cook on Sauté mode for 6–8 minutes, stirring occasionally, until the spaghetti is tender.

  10. Stir until the cheese melts and the sauce becomes creamy.
  11. Taste and adjust seasoning if needed. Garnish with parsley and serve warm.

Notes

  • Break spaghetti in half so it fits easily in the pot.
  • Stir the pasta occasionally while cooking to prevent sticking.
  • Add a splash of broth or milk if the sauce becomes too thick.
  • Bell peppers or mushrooms can be added for extra flavor.
