Instructions
Soak Skewers (if using wooden): Soak wooden skewers in water for at least 30 minutes. Skip if using metal skewers.
Marinate Chicken and Veggies: Place chicken in a large bowl and vegetables in a second large bowl. In a small bowl, whisk together all marinade ingredients. Pour all but 3 tablespoons of the marinade over the chicken. Toss the vegetables with the reserved marinade. Cover both bowls and marinate for 30 minutes (or refrigerate up to 4 hours).
Preheat Oven: Preheat oven to 400°F. Line a 13x18-inch baking sheet with parchment paper or foil for easy cleanup.
Assemble Skewers: Alternate threading the chicken and vegetables on the skewers. For best results, group 2–3 slices of onion together. Do not pack too tightly.
Bake: Arrange skewers on the prepared sheet pan. Bake for 20–25 minutes, flipping halfway through, or until chicken reaches 165°F internal temperature.
Optional Broil: For added char, broil 1–2 minutes, watching closely to prevent burning.
Serve: Garnish with lemon wedges and chopped parsley if desired. Serve warm.
Notes
Make-Ahead Tips: You can marinate and assemble the skewers up to 4 hours in advance. For a quick dinner, chop the chicken and veggies a day ahead and store separately in the fridge.Storage: Remove food from skewers and store in an airtight container in the refrigerator for up to 3 days.Freezing: Chicken can be frozen in marinade for up to 3 months. Thaw in the refrigerator overnight. Do not freeze vegetables — they will become mushy.
