Ingredients

Ingredients

  • 2 tablespoons olive oil
  • 2 tablespoons butter
  • 2 pounds boneless and skinless chicken thighs
  • Salt and pepper to taste
  • 1 medium onion, finely diced
  • 4 cloves garlic, minced
  • ½ cup chicken stock or dry apple cider vinegar
  • 1 teaspoon dried thyme
  • 3 tablespoons Dijon mustard
  • 1 cup heavy whipping cream
  • ½ cup Parmesan cheese, grated
  • 2 cups baby spinach leaves

Instructions

  • Step 1: Sauté the Aromatics - Set your Instant Pot to the ‘Sauté’ function. Add olive oil and butter, then sauté diced onion for 3-4 minutes until translucent. Add minced garlic and sauté for an additional 30 seconds.
  • Step 2: Season and Add the Chicken - Pat chicken thighs dry, season with salt and pepper, and brown in the pot for 4-5 minutes.
  • Step 3: Deglaze the Pot - Pour in chicken stock or apple cider vinegar to deglaze, scraping up browned bits from the bottom.
  • Step 4: Add Mustard and Thyme - Stir in dried thyme and Dijon mustard, coating the chicken evenly.
  • Step 5: Pressure Cook the Chicken - Secure the lid and cook on high pressure for 10 minutes. Release pressure manually.
  • Step 6: Make it Creamy - Stir in heavy whipping cream and Parmesan cheese until well combined. Simmer until sauce thickens slightly, then fold in spinach until wilted.
  • Step 7: Serve and Enjoy - Spoon the creamy mustard chicken over rice or serve with roasted vegetables.

Notes

For best results, use high-quality Dijon mustard. You can substitute chicken thighs with chicken breasts, but adjust cooking time accordingly.
