Make dinner easy and delicious with this mouth-watering Chicken Pesto recipe! It's a dinner everyone will want on regular rotation each week, and you'll love it too because of how simple it is to throw together!
Place the chicken, onions, tomatoes, garlic, 1 tablespoon pesto, Italian seasoning, water, salt, and pepper in the inner liner of your Instant Pot or pressure cooker.
Cook for 5 minutes at high pressure. At the end of the cooking time, allow the pot to rest undisturbed for 10 minutes and then release any remaining pressure.
Add the whipping cream and pesto to the vegetables in the pot. Using an immersion blender, purée until you have a smooth and creamy sauce. At this point, if you would like a thicker sauce, turn the Instant Pot to Sauté and when the sauce boils, add the Xanthan gum or cornstarch slurry and cook until the sauce has thickened.
