Bright, citrus-glazed Cornish hens with a tangy-sweet finish are a high protein, elegant family dinner. These individual-portion birds make entertaining effortless and impressive.
Preheat the oven to 400°F (204°C) and pat the Cornish hens dry with paper towels for better browning.
In a small saucepan over medium-low heat, melt the butter. Add orange juice, lemon juice, honey, minced garlic, and half the rosemary; simmer until syrupy, about 6-8 minutes, stirring occasionally.
Rub the hens with olive oil, then season thoroughly with salt, black pepper, and the remaining rosemary, making sure to season cavity and skin evenly.
Arrange hens breast-side up on a rack in a roasting pan; brush generously with half the citrus glaze, reserving the rest.
Roast for 45 minutes, basting twice with remaining glaze. Increase oven to 425°F for the last 10 minutes, roasting until the skin is golden and the thickest part of the thigh registers 165°F. Let rest 10 minutes before serving.
