Making Sticky Guinness Chicken is quite easy if you follow these simple steps:

1. Prepare the Marinade: In a bowl, whisk together the Guinness, brown sugar, soy sauce, apple cider vinegar, minced garlic, Dijon mustard, paprika, and black pepper until well combined.
2. Marinate the Chicken: Place the chicken breasts in a resealable plastic bag or shallow dish. Pour the marinade over the chicken, ensuring it’s well coated. Seal the bag or cover the dish, and refrigerate for at least 30 minutes, or up to overnight for maximum flavor.
3. Preheat the Oven or Grill: If using an oven, preheat it to 375°F (190°C). If grilling, preheat your grill to medium-high heat.
4. Remove Chicken from Marinade: Take the chicken breasts out of the marinade, letting excess liquid drip off. Reserve the marinade for later use.
5. Sear the Chicken: In a large, oven-safe skillet, heat the olive oil over medium-high heat. Add the chicken breasts and sear for about 3-4 minutes on each side until golden brown.
6. Add Marinade and Bake: If using the oven, pour the reserved marinade over the chicken and transfer the skillet to the preheated oven. Bake for 20-25 minutes or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
7. Glaze the Chicken: If grilling, place the chicken on the grill and brush with the reserved marinade. Grill for about 6-7 minutes on each side, basting occasionally, until cooked through.
8. Rest the Chicken: Once cooked, remove the chicken from the oven or grill and let it rest for about 5 minutes before slicing.
9. Garnish and Serve: If desired, garnish with fresh parsley for a pop of color. Serve the Sticky Guinness Chicken with the remaining glaze drizzled on top.

These steps will guide you to create a dish that’s not only flavorful but also visually stunning.
