Preheat your oven to 200°C (390°F) and line a baking sheet with parchment or foil for easy cleanup.
Combine minced garlic, olive oil, lemon juice, smoked paprika, cumin, and a pinch of salt in a mixing bowl. Whisk until well blended and fragrant.
Add the chicken chunks to the marinade and toss gently to coat all pieces evenly. Let sit for at least 10 minutes to absorb the flavors.
Thread the marinated chicken pieces onto skewers, alternating with colorful bell pepper chunks to add vibrant color and sweetness.
Place the skewers onto the prepared baking sheet, spacing them slightly apart to allow even roasting.
Bake in the oven for 15–20 minutes, turning the skewers once halfway through, until the chicken is golden with a slight char and juices run clear.
Optional: broil the skewers for an additional 2–3 minutes to enhance the charred, smoky edges, watching closely to prevent burning.
Remove the skewers from the oven and let rest for 5 minutes, allowing the juices to redistribute and keeping the meat tender.
Finish with a squeeze of fresh lemon and a sprinkle of herbs if desired, then serve hot with your favorite sides.
