This aromatic grilled chicken with rosemary and garlic is a fantastic way to elevate a simple barbecue. By cooking the chicken over a bed of fresh herbs and aromatics, the meat absorbs a deep, savoury flavour while remaining incredibly moist. The addition of charred spring onions provides a mild sweetness and a pleasant texture that complements the crispy, golden skin of the bird.
As a diabetes-friendly main course, this dish focuses on high-quality protein and fragrant seasonings rather than sugary marinades. It is an excellent choice for a healthy family lunch or a weekend garden gathering. Serve it alongside a fresh green salad or some steamed seasonal greens for a light, nutritious meal that feels truly indulgent without the extra carbohydrates.

Ingredients for Garlic-and-Rosemary Grilled Chicken with Spring onions
1 3 1/2–1.8kg chicken, backbone removed
Kosher salt, freshly ground pepper
4 sprigs rosemary
2 heads of garlic, halved crosswise
2 bunches red spring onions
2 tablespoons olive oil, divided
1 tablespoon onion or chive blossoms (optional)
How to make Garlic-and-Rosemary Grilled Chicken with Spring onions
Prepare grill for medium heat. Season chicken with salt and pepper. Place rosemary, garlic, and 1 bunch of spring onions in a layer on grill.
Place chicken, skin side up, on top of aromatics. Cover grill and cook until chicken is nearly cooked through, 35–40 minutes (aromatics will be thoroughly charred).
Brush chicken with 1 tablespoon oil and place skin side down, directly onto grates (you can discard aromatics at this point). Grill until chicken is cooked through and skin is crisp, 10–15 minutes longer. Transfer to a cutting board and let rest 10 minutes before cutting into pieces.
Meanwhile, toss remaining bunch of spring onions with remaining 1 tablespoon oil on a rimmed baking sheet and grill until tender and lightly charred, about 5 minutes.
Serve chicken with grilled spring onions alongside, topped with onion blossoms, if desired.
