Servings 4

Equipment

  • Meat Thermometer Use a probe thermometer to monitor the internal temp in real-time.
  • Blender/Immersion Blender Essential for emulsifying the oil and mustard into a thick marinade.
  • Cast Iron Skillet or Sheet Pan For the oven method, a wire rack over a sheet pan is best for airflow.

Ingredients
  

  • 1 whole chicken 4–5 pounds, spatchcocked
  • 1 tsp dried basil
  • 1 tsp dried rosemary
  • 1 tsp dried oregano
  • 1 tsp dried thyme
  • 1 tsp dried parsley
  • 3 cloves garlic
  • 2 tsp salt
  • ½ tsp black pepper
  • ½ cup rice wine vinegar
  • ¼ cup Dijon mustard or yellow mustard
  • ½ cup olive oil

Instructions
 

  • Spatchcock the chicken by removing the backbone and flattening it.
  • In a blender, food processor, or with an immersion blender, combine all marinade ingredients. Blend until smooth and emulsified.
  • Rub marinade thoroughly over the chicken (including under the skin if possible).
  • Marinate at least 2 hours, preferably overnight.

Smoker Method

  • Preheat smoker to 325°F.
  • Cook until internal temperature reaches 125°F.
  • Increase smoker temperature to 375°F.
  • Continue cooking until internal temperature reaches 163°F.
  • Remove and rest until it reaches 165°F.

Oven Method

  • Preheat oven to 375°F.
  • Roast 40–50 minutes until internal temperature reaches 160–163°F.
  • Broil briefly for crisp skin if desired.
  • Remove and rest until it reaches 165°F.

Notes

Why Pull at 163°F?

Chicken continues cooking after removal from heat.
If you wait until it hits 165°F inside the oven or smoker, it will overshoot and dry out.
Pulling at 163°F gives you:
  • Juicy breast meat
  • Fully cooked thighs
  • No dryness
It’s a small detail that makes a huge difference.
