Ingredients

• 3 lbs chicken leg quarters or thighs, or a mix
• 1 cup soy sauce
• 1/2 cup vinegar (cane or white)
• 1/4 cup calamansi juice (or substitute with equal parts lemon and lime juice)
• 1 whole head garlic, minced or crushed
• 2 stalks lemongrass, tough outer layers removed, bottom third smashed and finely chopped
• 1 tablespoon freshly ground black pepper
• 1 tablespoon sugar (brown or white)
• 1 teaspoon paprika (for color, optional)
• 1/2 teaspoon turmeric powder (optional, for deeper color)
• Salt to taste
• 1/2 cup vegetable oil or coconut oil (for basting)
• 1/4 cup annatto oil (Achiote oil) (for color and flavor)
• Additional calamansi or lemon wedges for serving

Step-by-Step Instructions

1. Prepare the Chicken: Score the chicken pieces deeply (especially on the thicker parts) to allow the marinade to penetrate fully. Place the chicken in a large, non-reactive bowl or sealable bag.
2. Create the Marinade: In a separate bowl, combine the soy sauce, vinegar, calamansi juice, minced garlic, chopped lemongrass, black pepper, sugar, paprika, and turmeric (if using). Mix thoroughly until the sugar dissolves.
3. Marinate the Chicken: Pour about three-quarters of the marinade mixture over the chicken. Reserve the remaining one-quarter of the marinade—this will be used later for basting and cooking safely. Mix everything well, ensuring the chicken is completely coated.
4. Refrigerate: Cover the bowl or seal the bag and refrigerate for at least 4 hours, but ideally overnight (12 to 24 hours) for the best flavor saturation.
5. Prepare the Basting Liquid: About 30 minutes before grilling, prepare the basting liquid. In a small saucepan, gently heat the vegetable oil, the reserved undiluted marinade, and the annatto oil until warmed through (do not boil). Stir well to combine the colors.
6. Preheat the Grill: Preheat your grill (charcoal is highly recommended for authentic flavor) to medium heat, aiming for about 350°F (175°C). If using charcoal, let the coals burn until they are covered in white ash. Clean and lightly oil the grates.
7. Grill the Chicken: Remove the chicken from the marinade, letting any excess drip off (discard the used marinade). Place the chicken pieces on the oiled grill grates, skin-side down first if possible.
8. Baste and Cook: Grill for about 5–7 minutes on the first side until nice grill marks appear. Flip the chicken. Begin basting generously with the annatto oil mixture every few minutes on both sides.
9. Continue Cooking: Continue flipping and basting every 4–6 minutes until the chicken is cooked through. The internal temperature should register 165°F (74°C) in the thickest part. Total grilling time is usually 20–30 minutes, depending on the heat and thickness of the cuts. The exterior should be beautifully charred and deep orange-yellow.
10. Rest and Serve: Remove the grilled chicken inasal from the heat and let it rest for 5 minutes before serving immediately with rice and extra calamansi.

Expert Tips / Pro Tips

• Use Charcoal: For the most authentic smoky flavor profile characteristic of true inasal, charcoal grilling is highly recommended over gas.
• Don’t Skip the Lemongrass: Lemongrass is crucial for the distinct aroma and taste of inasal. Ensure you smash it sufficiently so its oils release into the marinade.
• Annatto Oil is Key: Annatto seeds (achiote) provide the signature deep orange-yellow color. You can buy pre-made annatto oil or quickly infuse neutral oil by heating it with annatto seeds, then straining.
• Discard Used Marinade: Never reuse the marinade that touched the raw chicken for basting. Always reserve a portion separately for the basting mixture, as detailed in the instructions.
• Patience in Marinating: While 4 hours is sufficient, marinating chicken inasal overnight drastically improves flavor absorption, yielding superior results.

Variations & Substitutions

• Calamansi Substitute: If fresh calamansi is unavailable, use a 50/50 mix of fresh lemon juice and fresh lime juice. Do not use bottled citrus juices if possible, as the fresh flavor is far superior.
• Spice Level: For a spicy kick, add 1 teaspoon of crushed red pepper flakes to the marinade mixture.
• Vegetable Skewers: Thread chunks of onions, bell peppers, and pineapple onto skewers and baste them with the leftover annatto oil mixture to serve alongside the chicken.
• Oven/Broiler Method: If grilling isn’t possible, bake the chicken at 400°F (200°C) for 35 minutes, basting every 10 minutes with the annatto oil mixture. Finish under the broiler for 2–3 minutes until slightly charred.

Serving Suggestions

Grilled chicken inasal is traditionally served piping hot over a generous bed of steamed white rice, often referred to as “sinangag” or garlic fried rice. It must be accompanied by dipping sauces. Classic accompaniments include fresh calamansi wedges for an extra squirt of acid, sinamak (vinegar with chilies and garlic), and sometimes a side of atchara (pickled green papaya).

Storage, Freezing & Reheating

Cooled, cooked grilled chicken inasal can be stored in an airtight container in the refrigerator for up to 3 to 4 days. For longer storage, wrap cooked chicken tightly in plastic wrap followed by aluminum foil, and freeze for up to 3 months. To reheat, the best method is to wrap the chicken in foil and bake it at 350°F (175°C) for about 15 minutes, or until warmed through. You can briefly place it on a hot grill for a moment to refresh the char.

Nutrition Information

Please note that nutrition facts are approximate and can vary significantly based on the exact cut of chicken, oil absorption, and portion size. This estimate is based on a standard serving of one leg quarter without rice.

FAQ

What makes Inasal different from regular grilled chicken?

The primary difference is the marinade base. Regular barbecue often uses sweet tomato or ketchup bases, whereas authentic inasal relies heavily on citrus (calamansi), savory soy sauce, garlic, and the indispensable smoky, earthy color and flavor provided by annatto oil.

Can I use chicken breast instead of thighs?

Yes, you can use chicken breast, but thighs are traditionally preferred because they stay moister during the grilling process. If using breast, ensure you marinate for the full time and take extra care not to overcook it.

What is the purpose of basting with the reserved marinade?

Basting with the reserved, uncooked portion of the marinade deepens the flavor during cooking. However, it is crucial never to baste with the marinade that has touched the raw chicken during the initial soaking period due to food safety concerns; always use a separate, clean portion for basting.

Where can I find annatto oil?

Annatto oil can often be found in the international or Latin American aisle of well-stocked major supermarkets. If unavailable, you can easily make it by gently heating achiote (annatto seeds) in a neutral oil like canola or vegetable oil until the oil turns deep orange, then straining out the seeds.

Ingredients

  

For the Chicken Marinade

• 1.5 kg Chicken leg quarters Cut in half or scored deeply
• 1 cup Calamansi juice Or substitute with 1/2 cup lemon juice + 1/2 cup orange juice
• 1 stalk Lemongrass White part only, bruised and roughly chopped
• 1/4 cup Soy sauce
• 1 tablespoon Garlic Minced
• 1 teaspoon Ginger Grated
• 1 teaspoon Black peppercorns Cracked
• 1 tablespoon Brown sugar

For the Annatto Basting Oil

• 1/2 cup Vegetable oil
• 2 tablespoons Annatto seeds (Achuete)
• 2 cloves Garlic Smashed
• 1 tablespoon Butter Optional, for richer flavor
• 1 teaspoon Fish sauce Patîs

Method

 

Instructions

1. In a large bowl, combine all marinade ingredients: calamansi juice, lemongrass, soy sauce, minced garlic, ginger, peppercorns, and brown sugar. Mix well.
2. Add the chicken pieces to the marinade, ensuring they are fully submerged. Cover the bowl and refrigerate for at least 4 hours, or preferably overnight for best flavor penetration.
3. Prepare the basting oil: Gently heat the vegetable oil in a small saucepan. Add the annatto seeds and smashed garlic. Simmer on low heat for 5-7 minutes until the oil turns a deep orange-red. Strain the oil, discarding the solids, and stir in the fish sauce and butter (if using). Set aside.
4. Preheat your grill to medium-high heat. Remove the chicken from the marinade, allowing excess liquid to drip off (discard the remaining marinade). Lightly brush the chicken with the annatto basting oil.
5. Grill the chicken over direct heat for 8-10 minutes per side, turning occasionally, until cooked through (internal temperature reaches 165°F or 74°C). During the last 5 minutes of grilling, frequently brush both sides with the basting oil to develop a nice glaze.
6. Remove the Inasal from the grill. Let it rest for 5 minutes before serving hot, traditionally alongside steamed rice and an extra dipping sauce of calamansi juice mixed with fish sauce.

Notes

For an authentic smoky flavor, use charcoal. If using a gas grill, you can place a small wood chip packet over the flame to impart smoke. The key flavor comes from the lemongrass infusion and the annatto oil coating.
