Barbecued chicken with romesco sauce

Barbecuing chicken is a time-honored tradition that enhances the flavor with a perfect char. This recipe for barbecued chicken is paired with romesco sauce made from roasted red peppers, almonds, garlic, and spices. It's a delicious way to enjoy outdoor cooking and impress your guests with a burst of bold flavors in every bite.

Instructions:

1. Preparation:
- Preheat your barbecue grill to medium-high heat.
- Rinse the whole chicken under cold water and pat it dry with paper towels.
2. Seasoning:
- Rub the chicken with olive oil, ensuring it’s well-coated to help it stay moist during grilling.
- Sprinkle the fresh thyme over the chicken, rubbing it into the skin and cavities for increased flavor.
3. Grilling the Chicken:
- Place the seasoned chicken on the barbecue grill.
- Grill the chicken, turning occasionally to ensure it cooks evenly. Use a meat thermometer to check for doneness; the internal temperature should reach 165°F (74°C) at the thickest part of the breast and thighs.
- Depending on the size of your chicken, it should take about 1 to 1.5 hours to cook.
4. Preparing the Fiery Romesco Sauce:
- While the chicken is cooking, prepare the red peppers by roasting them. Place them on the grill until their skins are charred and blistered. This should take about 10-15 minutes.
- Once the peppers are roasted, transfer them to a bowl and cover with plastic wrap or a kitchen towel to steam for about 10 minutes. This will make peeling the skin easier.
- Peel the skins off the peppers and remove the seeds.
5. Blending the Sauce:
- In a blender or food processor, combine the peeled red peppers, almonds, garlic cloves, vinegar, tomato puree, and chili powder.
- Blend the ingredients until you achieve a smooth, thick sauce. Taste and adjust seasoning if necessary.
6. Serving:
- Once the chicken is fully cooked, remove it from the grill and let it rest for about 10 minutes before carving.
- Serve the grilled chicken with a generous spoonful of the romesco sauce on the side or drizzled over the top.

A delicious barbecued chicken, paired with romesco sauce, is a perfect meal for any outdoor gathering. The combination of smoky, juicy chicken and the rich, spicy sauce will leave everyone craving for more. Follow the tips provided to ensure your chicken is cooked to perfection and your sauce is flawlessly blended for the ultimate dining experience.

Barbecued chicken with romesco sauce FAQ:

What is the ideal cooking time for the whole chicken on the grill?

The cooking time for a 3 lb whole chicken on a barbecue grill is approximately 1 to 1.5 hours. It’s important to grill the chicken at medium-high heat and turn it occasionally for even cooking.

How can I tell when the chicken is fully cooked?

To ensure the chicken is fully cooked, use a meat thermometer to check the internal temperature. It should reach 165°F (74°C) at the thickest part of the breast and thighs.

Can I make the romesco sauce in advance?

What can I substitute for almonds in the romesco sauce?

You can substitute almonds with other nuts like hazelnuts or walnuts. If you're looking for a nut-free option, consider using sunflower seeds, though the flavor will be slightly different.

Cooking Tips:

- 1: Ensure your grill is preheated to medium-high heat before placing the chicken on it. This helps to sear the chicken quickly and lock in juices.

- 2: Use a meat thermometer to check the internal temperature of the chicken. It should reach 165°F (75°C) for safe consumption.

- 3: Roast the red peppers until their skins are charred for a smoky flavor in your romesco sauce. Once charred, place them in a sealed container for a few minutes to make peeling off the skins easier.

- 4: Blend the romesco sauce ingredients until smooth but still with a bit of texture for a more authentic and hearty consistency.

- 5: Let the cooked chicken rest for 5-10 minutes before carving to allow the juices to redistribute, making for a juicier and more flavorful meal.
