Cut chicken in half or spatchcock it. Place the chicken in a large bowl and season generously with beer, vinegar, lime juice, 1 1/2 teaspoon salt, 1 1/2 teaspoons garlic powder, cumin, and oregano.
Transfer to a large bag and marinate overnight.
Remove chicken from marinade, and place both halves on a large oven-safe baking dish, skin side up. Discard the marinade.
Season the chicken with paprika, remaining 1/2 teaspoon garlic powder and 1/2 teaspoon salt.
Bake at 425°F for about 50 minutes, basting with the pan juices halfway through, until a thermometer inserted into the thickest part of the chicken registers 165°F. Let rest for 5 minutes before carving.
Aji Verde Sauce
Place all ingredients in a blender and puree until smooth. Serve over chicken, rice, beans, or plantains.
Notes
Nutrition is based on 4 ounces of cooked chicken breast with skin and ¼ of the sauce. Values will vary depending on the piece of chicken and amount of skin and sauce consumed.
Grilling Method:If you want to make this chicken on the grill, I would recommend cutting the chicken into individual pieces before you marinate. Position the grill rack 4-6 inches above the fire. Cook covered, turning often, about 20-25 minutes, until juices run clear when the thigh is pierced with a knife.
