Step 1: Sauté the Chicken - Select the sauté function on your Instant Pot. Add the sun-dried tomato oil and butter to the pot. Once melted and bubbly, season the chicken breasts with ½ teaspoon of salt and the black pepper. Place the chicken in the pot and sauté for about 3-4 minutes on each side, just until they are browned. Remove the chicken and set it aside.
Step 2: Cook the Aromatics - In the same pot, add the minced garlic and cook for about 30 seconds until fragrant, stirring constantly.
Step 3: Deglaze the Pot - Pour in the chicken stock, scraping the browned bits off the bottom of the pot. Stir in the Italian seasoning, chili flakes, and the remaining ½ teaspoon of salt.
Step 4: Add Chicken and Sun-Dried Tomatoes - Return the browned chicken to the pot, placing it on top of the garlic mixture. Sprinkle the chopped sun-dried tomatoes over the chicken.
Step 5: Pressure Cook - Close the lid of the Instant Pot and set the valve to sealing. Pressure cook on high for 8 minutes. Once done, do a quick release of the pressure.
Step 6: Make the Creamy Sauce - Once the pressure is released, take the chicken out and add the heavy cream and parmesan cheese to the pot, stirring until the sauce is creamy and smooth.
Step 7: Add Spinach - Stir in the baby spinach leaves until wilted and incorporated into the sauce. Slice the chicken or serve whole, drizzling the sauce over the top.
Step 8: Serve and Enjoy! - Serve over rice, pasta, or with crusty bread for dipping.
Notes
For extra flavor, marinate the chicken in olive oil, lemon juice, and Italian herbs for a few hours before cooking. Adjust chili flakes to your spice preference.
