Best Chicken Inasal Recipe: Grilled Perfection with Filipino Flavors

I’ve perfected my Chicken Inasal recipe through years of experimentation, combining traditional Filipino flavors with modern grilling techniques. This dish delivers tender, juicy chicken with a crispy exterior, all infused with aromatic spices.

The secret lies in the marinade, where a blend of vinegar, citrus, and spices works to tenderize the chicken while building complex flavor layers. Grilling to perfect char completes this authentic Filipino dish that’s sure to become a favorite.

Ingredients for Best Chicken Inasal

Gather these aromatic ingredients to create authentic Filipino Chicken Inasal at home easily.

The marinade is where the magic happens. Calamansi gives that distinct Filipino citrus flavor—if you can’t find it, fresh lime is the next best thing. For the chicken, bone-in thighs are essential for that juicy, tender texture. Most Asian markets carry calamansi or you can substitute with lime.

No lemongrass? Skip it or use lemon zest as a substitute—the citrus flavor still works. For annatto, soak the seeds in oil for 30 minutes to get that signature red color. If you can’t find annatto, paprika gives a similar hue. The fish sauce is optional but adds depth—use a high-quality brand like Red Boat if you choose to include it.

Marinating overnight is best, but 4 hours minimum if you’re short on time. Grill over medium-high heat to get that perfect char. Leftovers keep for 3-4 days in the fridge. The flavors actually meld together better the next day.

Step-by-Step Instructions for Grilled Chicken Inasal

Here’s the method that delivers authentic Filipino-style grilled chicken every time.

Step 1: Prepare the Marinade

Start by combining the 0.5 cup White Vinegar, 0.25 cup Calamansi Juice, 6 cloves Garlic Cloves, 2 whole Lemongrass Stalks, 1 tbsp Black Pepper, 2 tsp Salt, and 2 whole Bay Leaves in a blender or food processor. Blend until the mixture is smooth and the aromatics are well-processed. I like to strain this mixture through a fine-mesh sieve into a large bowl to remove any solids, ensuring a smooth marinade.

The marinade should have a balanced tanginess from the vinegar and calamansi juice, with a deep aroma from the garlic and lemongrass. If you’re using fish sauce, now is the time to add the 1 tbsp Fish Sauce to enhance the umami flavor. Whisk everything together until well combined.

Step 2: Marinate the Chicken

Add the 2 lb Chicken Thighs to the marinade, making sure they’re fully submerged. If necessary, you can weigh down the chicken with a plate to keep it under the liquid. Cover the bowl with plastic wrap and refrigerate for at least 4 hours, though overnight is best for maximum flavor penetration. The longer it marinates, the more tender and flavorful the chicken will be.

During the marinating process, the acidity from the vinegar and calamansi juice will work to break down the proteins in the chicken, resulting in tender meat. You’ll notice the chicken taking on a slightly pinkish hue from the annatto seeds if you’ve added them to the marinade.

Step 3: Prepare the Annatto Oil

While the chicken is marinating, prepare the annatto oil by heating the 2 tbsp Annatto Seeds in the 0.25 cup Coconut Oil over low heat. Let it simmer gently for about 5 minutes until the oil takes on a deep red-orange color and the seeds have released their color and flavor into the oil. Strain the oil through a fine-mesh sieve into a clean bowl, discarding the seeds. This annatto oil will be used to brush the chicken before grilling, giving it that characteristic inasal color and flavor.

The annatto oil should be vibrant and aromatic, with a subtle earthy scent from the seeds. If you’re not using it immediately, let it cool completely before storing it in an airtight container in the refrigerator for up to a week.

Step 4: Grill the Chicken

Preheat your grill to medium-high heat. Remove the chicken from the marinade, letting any excess liquid drip off. Brush the chicken thighs generously with the prepared annatto oil on all sides. This not only adds flavor but also gives the chicken its signature color.

Grill the chicken for 8-10 minutes per side, or until it reaches an internal temperature of 165°F. The skin should be crispy and slightly charred, with a beautiful reddish hue from the annatto oil. If you’re using a charcoal grill, you might need to adjust the cooking time based on the heat intensity.

Step 5: Glaze and Serve

During the last 2 minutes of grilling, brush the chicken with a glaze made by mixing the 2 tbsp Brown Sugar with a bit of the annatto oil. This adds a sweet and sticky element to the chicken, balancing out the tanginess from the marinade. Once cooked, let the chicken rest for 5 minutes before serving to allow the juices to redistribute.

Serve the grilled chicken inasal hot, garnished with additional calamansi or lime wedges on the side. The chicken should be juicy on the inside with a crispy, flavorful exterior. Enjoy it with steamed rice or as part of a larger Filipino-inspired meal.

Make-Ahead Tips for best chicken inasal

Marinade Preparation

Prepare the marinade up to 24 hours in advance by blending all ingredients except the chicken. Store it in an airtight container in the refrigerator. This allows the flavors to meld together beautifully, enhancing the overall taste of the dish.

Chicken Preparation

You can marinate the chicken up to overnight in advance.

Annatto Oil Preparation

The annatto oil can be prepared up to a week in advance. Simply store it in an airtight container in the refrigerator. This not only saves time on the day of grilling but also allows the flavors to deepen. When you’re ready to grill, give it a good stir before using.

Grilling Preparation

If you want to get ahead, you can even grill the chicken partially (until it reaches about 145°F internally) and then finish it off when you’re ready to serve. Store the partially cooked chicken in the refrigerator and finish grilling when needed. This technique works well for managing timing during a party or gathering.

Reheating Tips

For leftovers, reheat the chicken in the oven at 350°F for about 10-15 minutes, or until warmed through. You can also reheat it on the grill for a few minutes on each side to restore that crispy exterior. Be sure to check that it reaches an internal temperature of 165°F for food safety.

Storage Tips

Store leftover chicken inasal in an airtight container in the refrigerator for up to 4 days. The flavors actually meld together better the next day, making it a great candidate for meal prep. When reheating, you might need to add a splash of water or broth to keep it moist. 🔥
