  • 2 pounds boneless skinless chicken thighs or breast cubed
  • 1 teaspoon Italian seasoning
  • 1 teaspoon sea salt
  • ½ teaspoon fresh ground black pepper
  • ¼ cup butter
  • ¼ cup chopped onion
  • 1 teaspoon minced garlic
  • 10 ounces canned diced tomatoes
  • 1 ½ cups chicken broth
  • ½ cup heavy cream
  • ¾ teaspoon xanthan gum
  • 2 cups sharp cheddar cheese divided
  • ½ cup parmesan cheese shredded
  • 1 can palmini noodles drained and rinsed or 2 zucchini, spiralized (see tips and tricks)


Stovetop Instructions

  • Preheat broiler to high.
  • In a large bowl, toss the chicken with the Italian seasoning, salt, and pepper.
  • Melt the butter in a large oven-safe skillet over medium-high heat.
  • Add the chicken and cook, stirring occasionally, for 6 minutes.
  • Add the onion and garlic to the skillet and cook for 3 minutes longer.
  • Stir in tomatoes, broth, and cream. Bring to a simmer over medium heat. Stir in xanthan gum and cook for 5 minutes, until the sauce starts to thicken.
  • Reduce the heat to low and add 1 cup of cheddar cheese and the parmesan cheese. Cook until melted, about 3 to 4 minutes.
  • Stir in palmini noodles and top with the remaining 1 cup of cheddar cheese.
  • Cook under the broiler until the cheese melts, about 3 minutes.

Instant Pot Instructions

  • Set your Instant Pot to Saute High. Add the butter. When it is melted, add the chicken and cook for 3 minutes. Add the onion and garlic and cook for 3 minutes longer.
  • Add the chicken broth and scrape up any brown bits.
  • Add the tomatoes, cream, and xanthan gum.
  • Hit cancel.
  • Set your instant pot to high pressure and set the time to 2 minutes. When the time is up, do an instant release and stir.
  • Add 1 cup of cheddar cheese and parmesan cheese. Place the lid back on the pot until the cheese is melted. Stir.
  • Stir in the palmini noodles (if using) and top with the remaining cheese. Replace the lid and let sit until the cheese is melted.
  • If desired, you can cook under the broiler for 3 minutes or use your air crisp lid.
