Whole fish butterflied and grilled with a two-sided chile paste is Guerrero's coastal masterpiece. This high protein, keto-friendly dish is a healthy, fresh option for family beachside meals.
Butterfly the whole snapper by cutting along the backbone, then open it flat, removing the backbone entirely for easier grilling.
Soak the guajillo and ancho chiles in warm water for 15 minutes to soften them, then remove seeds and stems.
Blend softened chiles with onion, garlic, lime juice, olive oil, salt, and black pepper to produce a smooth, vibrant paste.
Rub half the chile paste on the flesh side and the other half on the skin side of the fish, ensuring even coverage; marinate for at least 30 minutes.
Preheat the grill to medium-high; oil the grates, then grill the fish skin-side down first for 6–8 minutes, cover, then flip carefully and cook the flesh side for an additional 6–8 minutes, or until fish is just cooked through and flakes easily with a fork.
