Creating this Spicy Maple Glazed Chicken with Cheddar Polenta is straightforward when you follow these steps:

1. Prepare the Chicken Marinade: In a bowl, whisk together maple syrup, soy sauce, chili powder, garlic powder, smoked paprika, cayenne pepper, salt, and pepper.
2. Marinate the Chicken: Place chicken breasts in a shallow dish and pour the marinade over them. Cover and let marinate for at least 30 minutes, or up to 2 hours in the refrigerator for more flavor.
3. Preheat the Oven: Preheat your oven to 375°F (190°C).
4. Bake the Chicken: Remove the chicken from the marinade, reserving the liquid. Place chicken breasts on a baking sheet and pour the reserved marinade over them. Bake for 25-30 minutes or until the internal temperature reaches 165°F (74°C).
5. Prepare the Polenta: While the chicken is baking, bring 4 cups of water or chicken broth to a boil in a saucepan. Gradually whisk in the polenta, stirring constantly to prevent lumps.
6. Cook the Polenta: Reduce heat to low and cook for about 20-25 minutes, continuing to stir frequently until it thickens. Remove from heat and stir in cheddar cheese and butter. Season with salt and pepper.
7. Rest the Chicken: Once done, remove chicken from the oven and let it rest for 10 minutes, which allows juices to redistribute.
8. Slice the Chicken: After resting, slice the chicken breasts into strips for serving.
9. Plating: Serve the sliced chicken over a generous bed of cheddar polenta. Drizzle any remaining glaze from the baking tray over the top for extra flavor.
10. Garnish: Sprinkle with fresh parsley if desired and serve hot.
