1 medium red onion – Halved, peeled, and sliced into ¼-inch pieces, the onion provides a subtle sweetness when roasted along with other ingredients.

5 tablespoons olive oil – This versatile oil coats the vegetables and chicken, ensuring they roast evenly while enhancing their flavors.

1 ½ teaspoons kosher salt – This essential seasoning boosts the natural flavors of all the ingredients during cooking.

½ teaspoon ground black pepper – This simple spice adds a kick of warmth and enhances the overall taste without overwhelming it.

2 cloves garlic – Pressed or finely minced, garlic injects an aromatic depth that pairs wonderfully with the mustard and maple syrup.

2 tablespoons Dijon mustard – This tangy condiment adds a layer of zesty flavor that brightens the dish.

2 tablespoons maple syrup – The maple syrup balances the Dijon and adds a sweet, caramelized note as it bakes.

2 tablespoons balsamic vinegar – This ingredient contributes a tangy element that deepens the flavors of the marinade.

2 teaspoons minced fresh thyme leaves – Fresh thyme offers a fragrant herbal note that rounds out the dish beautifully; dried thyme is a great substitute if fresh isn’t available.

How to Make Sheet Pan Chicken, Brussels Sprouts & Butternut Squash

Follow these simple steps to prepare this delicious Sheet Pan Chicken, Brussels Sprouts & Butternut Squash:

Step 1: Preheat the Oven
Preheat the oven to 425°F (220°C). It’s important to get your oven nice and hot so the chicken and vegetables can roast perfectly.

Step 2: Prepare the Vegetables
Place the diced butternut squash, halved Brussels sprouts, and sliced red onion in the center of a large, rimmed sheet pan. Drizzle with 2 tablespoons of olive oil, add ½ teaspoon of kosher salt, and ¼ teaspoon of black pepper. Toss everything together to coat, then spread the vegetables into an even layer on the pan. Bake for 20 minutes, letting the vegetables soften slightly.

Step 3: Make the Marinade
In a large bowl, combine the minced garlic, Dijon mustard, maple syrup, balsamic vinegar, remaining 3 tablespoons of olive oil, 1 teaspoon of salt, ¼ teaspoon of black pepper, and minced thyme. Stir well to create a delicious marinade.

Step 4: Coat the Chicken
Once the vegetables have roasted for 20 minutes, remove the pan from the oven. Add the diced chicken to the bowl with the marinade and stir to ensure every piece is well coated. Spoon the chicken pieces evenly over the roasted vegetables on the sheet pan. Drizzle any remaining marinade over the top for extra flavor.

Step 5: Roast Everything Together
Return the pan to the oven and bake for an additional 15 to 18 minutes or until the chicken is fully cooked through, reaching an internal temperature of 165°F (74°C) and the veggies are tender and slightly caramelized.

Step 6: Garnish and Serve
Once everything is cooked to perfection, remove it from the oven and sprinkle with extra fresh thyme for a pop of color and flavor. Transfer to plates and enjoy the lovely mingling of flavors in every bite—this dish is a true winner at the dinner table!
