Pat the chicken dry and season both sides with Italian seasoning, salt, and pepper.
4 boneless, skinless chicken breasts, 1 teaspoon Italian seasoning, Kosher salt and freshly ground black pepper
Set your Instant Pot to Sauté. Once hot, add in the butter and olive oil. Add in the chicken, in batches if needed, and cook until both sides are browned, about 2-3 minutes per side. Remove from the Instant Pot and set aside.
1 tablespoon unsalted butter, 1 tablespoon olive oil
Add in the garlic and sauté for 30 seconds until fragrant. Pour in the chicken stock and scrape up any browned bits from the bottom of the pot. Turn off the Sauté function.
4 cloves garlic, ½ cup low-sodium chicken broth
Return the chicken to the pot, secure the lid and pressure cook for 4 minutes. Let natural release for 10 minutes before releasing any remaining pressure.
Set the chicken aside and set the Instant Pot to Sauté. Stir in the heavy cream, sun dried tomatoes, Parmesan, and spinach. Cook, stirring, until the spinach is wilted and the parmesan is melted.
1 cup heavy cream, 8.5 ounces sun-dried tomatoes, 1 cup baby spinach, ½ cup freshly grated Parmesan cheese
Turn off the Instant Pot, return the chicken to the pot, and spoon over the sauce. Garnish with herbs and serve.
Fresh parsley or basil
