How to Make Sheet Pan Balsamic Chicken with Brussels, Grapes, and Red Onion Recipe

Step 1: Prepare the oven and pan

Start by preheating your oven to a high heat of 425°F. This temperature ensures your chicken gets that perfect golden crisp and your Brussels sprouts caramelize just right. Line a large sheet pan with parchment paper or foil for easy cleanup and to prevent sticking.

Step 2: Season the chicken

In a spacious bowl, toss the chicken thighs with olive oil, dried thyme, garlic powder, salt, and black pepper. This simple seasoning blend is classic yet full of flavor, creating a beautiful savory base that will absorb the tangy glaze later on.

Step 3: Prepare the vegetables and grapes

Grab another bowl and combine the halved Brussels sprouts, seedless red grapes, and red onion wedges. Drizzle them with olive oil, sprinkle salt and pepper, then toss everything until each piece is evenly coated. This mixture promises a lively contrast of textures and natural sweetness.

Step 4: Arrange on the sheet pan

Spread the Brussels sprouts, grapes, and onions evenly across the prepared sheet pan. Nestle the seasoned chicken thighs among the vegetables and fruit, giving them room to roast without overcrowding. This setup ensures everything cooks uniformly and develops those gorgeous roasted edges.

Step 5: Make and apply the balsamic glaze

In a small bowl, whisk together balsamic vinegar, honey, and Dijon mustard until silky and smooth. Drizzle half of this glaze over the chicken and vegetable mixture before roasting. The initial coating will infuse the dish with that distinct sweet-tangy flavor as it bakes.

Step 6: Roast to perfection

Place the sheet pan into your preheated oven and roast for 25 to 30 minutes. You’re aiming for the chicken to reach an internal temperature of 165°F, while the Brussels sprouts become golden and tender. The grapes will soften beautifully, bursting with their natural sugars.

Step 7: Finish and serve

Once out of the oven, drizzle the remaining balsamic glaze over the entire pan. This final touch adds a glossy, irresistible sheen and an extra pop of flavor. Serve immediately to enjoy the dish at its most vibrant and warm.

Garnishes

Fresh herbs like chopped parsley or thyme make excellent garnishes, adding a burst of color and a fresh, herby note. A light sprinkle of toasted pine nuts or slivered almonds can also add a satisfying crunch and nutty dimension to the dish.

Side Dishes

This sheet pan meal is a complete dinner on its own, but you could pair it with a simple green salad for extra freshness or creamy mashed potatoes to soak up any extra balsamic glaze. For a low-carb option, a cauliflower rice or quinoa pilaf works beautifully alongside these flavors.

Creative Ways to Present

For a lovely presentation, arrange the chicken and veggies on a large platter, placing the grapes on top as a vibrant garnish. Drizzle a little extra balsamic glaze over the plate and sprinkle with fresh herbs for an elegant, rustic look that’s perfect for both weeknights and entertaining guests.

Make Ahead and Storage

Storing Leftovers

Simply transfer any leftovers into an airtight container and refrigerate. They will stay fresh for up to 3 days, making this a great option for quick lunches or reheated dinners.

Freezing

If you want to freeze this dish, place cooled leftovers in a freezer-safe container or bag. It should keep well for up to 2 months. Thaw overnight in the fridge before reheating to maintain flavor and texture.

Reheating

Reheat leftovers gently in a preheated oven at 350°F for 10-15 minutes or until warmed through. This method helps retain the crispness of the Brussels sprouts and moisture in the chicken better than microwaving.

FAQs

Can I use chicken breasts instead of thighs?

Absolutely! Chicken breasts can work well, but keep in mind they may dry out faster. Consider checking for doneness a bit earlier and possibly marinating them slightly to keep them juicy.

What can I substitute for red grapes?

If you don’t have red grapes, green grapes or even diced apples can add a similar burst of sweetness. Just make sure to adjust cooking time slightly if you use firmer fruits.

Is this recipe gluten-free?

Yes, this Sheet Pan Balsamic Chicken with Brussels, Grapes, and Red Onion Recipe is naturally gluten-free. Just double-check that your mustard and balsamic vinegar do not contain any gluten additives.

Can I make this recipe vegetarian?

Definitely! Swap the chicken for hearty tofu or tempeh and proceed with the same seasoning and roasting method. The balsamic glaze and veggies will still shine beautifully.

How can I make the balsamic glaze thicker?

Simply simmer the balsamic vinegar, honey, and Dijon mixture on low heat for a few minutes until it reduces and thickens to your liking. Be careful not to burn it, as balsamic vinegar can darken quickly.
