Creating the perfect Peri-Peri Chicken Roast involves several steps, but the end result is well worth the effort. Follow these instructions for a delightful meal:

Step 1: Prepare the Marinade

1. Blend the Chilies: In a blender or food processor, combine Peri-Peri chilies, garlic, smoked paprika, olive oil, lemon juice, red wine vinegar, oregano, cumin, salt, and black pepper. Blend until you achieve a smooth paste.
2. Taste and Adjust: Taste the marinade and adjust the seasoning if necessary. You can add more salt, lemon juice, or chilies based on your preference for heat and tang.

Step 2: Marinate the Chicken

3. Prepare the Chicken: Rinse the chicken under cold water and pat dry with paper towels. Make small incisions in the chicken to help the marinade penetrate.
4. Apply the Marinade: Generously rub the marinade all over the chicken, ensuring even coverage. Place the chicken in a bowl or zip-lock bag, and marinate in the refrigerator for at least 4 hours, ideally overnight.

Step 3: Roast the Chicken

5. Preheat the Oven: Preheat your oven to 400°F (200°C).
6. Prepare the Baking Tray: Place the marinated chicken in a roasting pan or on a baking sheet. Arrange lemon slices around and inside the chicken cavity.
7. Roast the Chicken: Roast in the preheated oven for 45-60 minutes, or until the internal temperature of the chicken reaches 165°F (74°C) and the skin is crispy and golden brown.
8. Rest the Chicken: Once cooked, remove the chicken from the oven and let it rest for 10 minutes before carving.
