Sheet-Pan Roasted Red Onion Chicken Recipe
Introduction
Sheet-Pan Roasted Red Onion Chicken is a simple, flavorful meal perfect for busy weeknights or family dinners. The combination of tender chicken and sweet roasted onions with a fragrant herb sauce makes every bite deliciously satisfying.

Ingredients
- 4 medium red onions, sliced into 3/4″ thick wedges
- 4 cloves garlic, peeled
- 1 tbsp. chopped fresh sage
- 1 tbsp. chopped fresh thyme, plus more for serving
- 1 tbsp. extra-virgin olive oil
- Kosher salt
- Freshly ground black pepper
- 1 (3 1/2- to 4-lb.) whole chicken, or 8 assorted chicken pieces
- 2 tsp. paprika
- 1 tbsp. unsalted butter, softened
- 1 tsp. sweet white vinegar
- Pinch of crushed red pepper flakes
Instructions
- Step 1: Arrange a rack in the center of your oven with no rack above it and preheat to 450°F. Place a baking sheet on the rack to preheat.
- Step 2: In a large bowl, combine the sliced onions, garlic, sage, thyme, and olive oil. Season with kosher salt and freshly ground black pepper. Toss gently to coat, separating some but not all onion layers.
- Step 3: Pat the chicken dry with paper towels. Season thoroughly on all sides with paprika, 4 teaspoons kosher salt, and 1 teaspoon black pepper. Arrange the chicken breast side up. Optionally, tie the legs together with kitchen twine and tuck wing tips underneath.
- Step 4: Carefully remove the hot baking sheet from the oven. Transfer the onion mixture to the sheet in an even layer. Place the chicken on top, centered over the onions.
- Step 5: Roast the chicken and onions, rotating the pan halfway through cooking, until an instant-read thermometer inserted into a thigh reads 165°F, about 60 to 70 minutes.
- Step 6: Transfer the chicken to a cutting board. Place half of the roasted onions and all garlic cloves into a blender. Add softened butter, sweet white vinegar, crushed red pepper flakes, 1/4 teaspoon salt, and 2 tablespoons water. Blend until smooth to create the onion sauce.
- Step 7: Break the chicken down into 8 pieces. Transfer the remaining onions to a platter and arrange the chicken pieces on top. Spoon the onion sauce over the chicken and garnish with additional fresh thyme before serving.
Tips & Variations
- For extra crispy skin, let the chicken sit uncovered in the refrigerator for an hour before roasting.
- Substitute fresh rosemary for sage and thyme if preferred, for a different herbaceous flavor.
- Add root vegetables like carrots or potatoes around the chicken for a complete sheet-pan meal.
- If using chicken pieces, reduce cooking time to about 45-55 minutes or until cooked through.
Storage
Store leftover chicken and onions in an airtight container in the refrigerator for up to 3 days. Reheat gently in a 350°F oven until warmed through to preserve the texture and flavor. The onion sauce can be stored separately and warmed on the stovetop or in the microwave before serving.

FAQs
Can I use other types of onions?
Yes, though red onions provide a nice balance of sweetness and color when roasted. Yellow or white onions can be used but may have a stronger flavor.
Is it necessary to tie the chicken legs?
Tying the legs helps the chicken cook evenly and maintain its shape but is optional. You can skip this step if preferred.

Ingredients
Chicken and Seasoning
- 1 (3 1/2- to 4-lb.) whole chicken, or 8 assorted chicken pieces
- 2 tsp. paprika
- 4 tsp. kosher salt, divided
- 1 tsp. freshly ground black pepper, plus more for seasoning
- 1 tbsp. unsalted butter, softened
- 1 tsp. sweet white vinegar
- Pinch of crushed red pepper flakes
Vegetables and Herbs
- 4 medium red onions, sliced into 3/4“-thick wedges
- 4 cloves garlic, peeled
- 1 tbsp. chopped fresh sage
- 1 tbsp. chopped fresh thyme, plus more for serving
- 1 tbsp. extra-virgin olive oil
- Kosher salt
- Freshly ground black pepper
Instructions
- Preheat Oven and Baking Sheet: Arrange a rack in the center of your oven with no rack above it and preheat the oven to 450°F (232°C). Place a baking sheet on the rack to preheat as well to ensure it is hot when adding the chicken and vegetables.
- Prepare Onion Mixture: In a large bowl, combine the sliced red onions, peeled garlic cloves, chopped fresh sage, chopped fresh thyme, and extra-virgin olive oil. Season generously with kosher salt and freshly ground black pepper. Toss carefully to coat, making sure to separate some layers of the onions but not all to maintain texture.
- Season the Chicken: Pat the whole chicken thoroughly dry with paper towels. Season all over with paprika, 4 teaspoons kosher salt, and 1 teaspoon freshly ground black pepper. Arrange the chicken breast-side up. Optionally, tie the legs together with kitchen twine and tuck the wing tips underneath to promote even cooking.
- Assemble on Hot Baking Sheet: Carefully remove the preheated baking sheet from the oven. Transfer the onion and herb mixture onto the sheet, spreading it evenly in a layer. Place the seasoned chicken on top of the onions, centering it on the sheet.
- Roast Chicken and Onions: Roast in the preheated oven for 60 to 70 minutes, rotating the pan halfway through cooking for even browning. The chicken is done when an instant-read thermometer inserted into the thickest part of a thigh reads 165°F (74°C).
- Make Onion Sauce: Transfer the roasted chicken to a cutting board to rest. Using a spatula, transfer half of the roasted onions and all the garlic cloves into a blender. Add softened unsalted butter, sweet white vinegar, a pinch of crushed red pepper flakes, 1/4 teaspoon kosher salt, and 2 tablespoons water. Blend until smooth to create a flavorful onion sauce.
- Serve: Break down the rested chicken into 8 pieces. Arrange the remaining roasted onions on a serving platter and place the chicken pieces on top. Spoon the blended onion sauce generously over the chicken and onions. Garnish with additional fresh thyme before serving.
Notes
- Tying the chicken legs and tucking wing tips is optional but helps in even cooking and a neater presentation.
- You can use chicken pieces instead of a whole chicken if preferred; adjust cooking time accordingly.
- Make sure the baking sheet is preheated for a crispier skin on the chicken.
- Leftovers can be refrigerated for up to 3 days and reheated gently to preserve moisture.
- This dish pairs beautifully with roasted potatoes or a fresh green salad.
