Island Chicken Inasal is the smoky, tangy, and incredibly juicy grilled chicken that defines Boracay’s famous beachside food stalls. It’s a Filipino classic where chicken is marinated in a bright blend of calamansi, vinegar, lemongrass, and annatto oil, then grilled over hot coals while being basted with more of that flavorful oil. This recipe recreates that iconic street-food experience at home, delivering caramelized, tender chicken with a signature orange-red glow that’s perfect for any backyard grill.
Ingredients
- 4 bone-in, skin-on chicken leg quarters (about 3 lb / 1.4 kg total)
- 1 cup (240 ml) calamansi juice (or ½ cup lime + ½ cup lemon juice)
- ½ cup (120 ml) cane vinegar (or white vinegar)
- 6 cloves garlic, minced
- 2 stalks lemongrass, bottom 4 inches bruised and chopped
- 1 tablespoon (15 g) brown sugar
- 1 teaspoon (5 g) black pepper
- 1 teaspoon (5 g) salt
- 1 tablespoon (15 ml) soy sauce
- ½ cup (120 ml) annatto oil (see note)
- For basting: additional ¼ cup (60 ml) annatto oil mixed with 2 tablespoons (30 ml) marinade
Note: Annatto oil is made by warming ½ cup (120 ml) neutral oil with 2 tablespoons (16 g) annatto seeds over low heat for 5 minutes, then straining. If unavailable, substitute with ½ cup oil mixed with 1 teaspoon paprika for color.
Instructions
- Make the marinade: In a large bowl, combine calamansi juice, vinegar, minced garlic, lemongrass, brown sugar, black pepper, salt, and soy sauce. Whisk until the sugar and salt dissolve.
- Marinate the chicken: Add the chicken leg quarters to the marinade, turning to coat each piece thoroughly. Cover the bowl and refrigerate for at least 4 hours, or up to 24 hours for deeper flavor. The longer it marinates, the more tangy and tender the meat becomes.
- Prepare the grill: When ready to cook, preheat your grill to medium-high heat (about 375–400°F / 190–205°C). If using charcoal, arrange the coals to one side for indirect heat.
- Make the basting oil: In a small bowl, mix the ¼ cup (60 ml) annatto oil with 2 tablespoons (30 ml) of the used marinade. This will be your basting sauce.
- Grill the chicken: Remove chicken from the marinade, letting excess drip off. Place the chicken skin-side down on the grill over medium-high heat. Cook for 5–7 minutes until the skin is golden brown and crisp.
- Flip and baste: Flip the chicken and brush generously with the basting oil. Move the chicken to the cooler side of the grill (indirect heat) if using charcoal, or reduce heat to medium if using gas. Cover and cook for another 15–20 minutes, turning and basting every 5 minutes, until the internal temperature reaches 165°F (74°C) as checked with a food thermometer (USDA FSIS safe minimum for poultry).
- Rest and serve: Remove the chicken from the grill and let it rest for 5 minutes. Serve hot with extra basting oil drizzled on top, if desired.
Tips
- Substitutions: If you can’t find calamansi, use a 1:1 mix of fresh lime and lemon juice—it mimics the tartness well. For annatto oil, you can steep annatto seeds in warm oil for 10 minutes, or just use regular oil with a pinch of paprika for color.
- Don’t skip the basting: The basting oil is what gives inasal its glossy, flavorful crust. Brush it on every time you flip, and don’t be shy—it’s what makes the skin irresistible.
- Watch for flare-ups: The sugar in the marinade can cause flare-ups on the grill. If you see flames, move the chicken to a cooler part of the grill immediately to prevent burning.
- Marinate overnight: For the most authentic flavor, marinate the chicken for 24 hours. The acid in the marinade tenderizes the meat and infuses it deeply.
Serving Suggestions
Serve Island Chicken Inasal with steamed jasmine rice, a side of garlic fried rice (sinangag), and a bowl of sinamak (vinegar with chili and garlic) for dipping. A fresh cucumber-tomato salad or grilled corn on the cob also complements the smoky, tangy flavors. For a true Boracay experience, serve it on a banana leaf with a wedge of calamansi on the side.
Variations
- Spicy Inasal: Add 2–3 bird’s eye chilies (siling labuyo) to the marinade for a fiery kick.
- Chicken Thighs: Use boneless, skinless thighs for faster cooking (about 10 minutes total). Reduce grilling time accordingly and check for doneness.
- Oven-Baked: If you don’t have a grill, bake the marinated chicken in a preheated 425°F (220°C) oven for 25–30 minutes, basting twice with oil, until the internal temperature reaches 165°F (74°C).
- Pork Inasal: Substitute pork shoulder chops or pork belly slices for chicken. Cook until the internal temperature reaches 145°F (63°C) for whole cuts (USDA FSIS safe minimum) and let rest for 3 minutes before serving.
Storage and Reheating
Refrigerate leftover grilled chicken in an airtight container for up to 4 days. To reheat, place the chicken on a baking sheet and warm in a 350°F (175°C) oven for 10–15 minutes, or until heated through. You can also microwave on high for 2–3 minutes, but the skin will lose its crispness. For best results, reheat on a grill or in a skillet over medium heat, basting with a little oil to restore moisture. Always reheat leftovers to an internal temperature of 165°F (74°C) before serving.
Frequently Asked Questions
What is annatto oil and where can I find it? Annatto oil is a vibrant orange oil made by infusing annatto seeds (achiote) in neutral oil. It’s commonly available in Latin or Asian grocery stores, or online. If you can’t find it, you can make it at home by heating ½ cup oil with 2 tablespoons of annatto seeds for 5 minutes, then straining. The oil adds color and a mild, earthy flavor—without it, the chicken won’t have that signature orange hue.
Can I use boneless chicken breasts instead of leg quarters? Yes, but breasts cook faster and can dry out. Marinate them for the same time, but grill for only 8–10 minutes total (4–5 minutes per side) over medium heat. Always check that the internal temperature reaches 165°F (74°C) with a thermometer.
Is there a substitute for calamansi juice? Calamansi is a small, sour Filipino citrus. The closest common substitute is a 50/50 mix of fresh lime and lemon juice. You can also use pure lime juice, but it will be slightly more tart. Avoid bottled calamansi juice, which often has added sugar and preservatives.
Why is my chicken burning on the grill? The sugar in the marinade can cause the outside to char before the inside is cooked. To prevent this, use medium heat, not high, and move the chicken to a cooler part of the grill if you see flames. Also, pat the chicken dry before grilling to remove excess marinade that can drip and cause flare-ups.
Can I marinate the chicken for more than 24 hours? You can, but the acid in the marinade will start to break down the meat’s texture, making it mushy. For best results, stick to 4–24 hours. If you need to prep ahead, freeze the chicken in the marinade for up to 3 months, then thaw in the refrigerator before grilling.
What is sinamak and how do I make it? Sinamak is a Filipino dipping vinegar made by steeping vinegar with garlic, chili, and sometimes peppercorns. To make a quick version, combine ½ cup (120 ml) cane vinegar, 2 minced garlic cloves, 1 sliced bird’s eye chili, and ½ teaspoon black peppercorns. Let it sit for at least 30 minutes before serving. It’s a tangy, spicy condiment that cuts through the richness of the chicken.
