Grilled Poussins with Lemon Herb Butter

These succulent grilled poussins with lemon herb butter offer a sophisticated and lighter alternative to a traditional roast chicken. By gently tucking a fragrant blend of fresh rosemary, thyme, and lemon zest beneath the skin, the delicate meat stays incredibly moist while the skin achieves a beautiful golden finish on the grill. The inclusion of lemon wedges in the cavity ensures a bright, citrusy aroma that permeates the bird during the slow, indirect cooking process.

This diabetes-friendly dish is high in protein and naturally low in carbohydrates, making it an excellent choice for a healthy, balanced dinner. Using the indirect grilling method ensures the small birds cook evenly without charring, resulting in a tender texture that pairs wonderfully with a crisp green salad or seasonal roasted Mediterranean vegetables. It is a simple yet impressive main course for any summer gathering or weekend family meal.

How to make Grilled Poussins with Lemon Herb Butter

Stir together 1 stick softened butter, thyme, rosemary, zest, 1 teaspoon sea salt, and 3/4 teaspoons pepper in a bowl until combined well.

Trim necks of poussins flush with bodies if necessary. Rinse poussins inside and out and pat dry. Discard any excess fat from opening of cavities, then sprinkle cavities with a total of 1 1/2 teaspoons sea salt and remaining 1/2 teaspoons pepper. Starting at cavity end of each bird, gently slide an index finger between skin and flesh of breasts and legs to loosen skin (be careful not to tear skin). Using a teaspoon measure or small spoon, slide 1 teaspoon herb butter under skin of each breast half and each drumstick (20ml per poussin), using your finger on outside of skin to push butter out of spoon.

Put 1 lemon wedge and 3 thyme sprigs into cavity of each poussin, then tie legs together with kitchen string and tuck wing tips under body. Arrange in a large pan. Pat poussins dry, then brush with melted butter and sprinkle with remaining teaspoon salt.

Open vents on bottom of grill and on lid. Light charcoal (80 to 100 briquettes) in chimney starter and pour evenly over 2 opposite sides of bottom rack, leaving about an 8-inch-wide space in centre of bottom rack free of coals. When charcoal fire is medium-hot (you can hold your hand 5 inches above grill rack for 3 to 4 seconds), remove poussins from pan and arrange in centre of lightly oiled grill rack with no coals underneath and cook, covered with lid, until thermometer inserted in fleshy part of a thigh registers 77°C, 35 to 50 minutes. (Add more briquettes if necessary during grilling to maintain heat.)

Preheat all burners on high, covered, 10 minutes, then reduce to moderately high. Turn off 1 burner (middle burner if there are 3) and put poussins on lightly oiled rack above shut-off burner. Remove poussins from pan, then grill, covered with lid, until thermometer inserted in fleshy part of a thigh registers 77°C, 35 to 45 minutes.
