Sheet Pan Maple Mustard Chicken with Brussels Sprouts
Juicy chicken thighs roasted with crispy Brussels sprouts and sweet potatoes in a tangy Dijon maple glaze. Easy 35-minute autumn dinner.
Table of contents
Sheet pan maple mustard chicken is the kind of effortless weeknight dinner that feels like a cozy weekend feast. In about 15 minutes of hands-on prep, everything comes together on a single rimmed baking sheet: bone-in chicken thighs tossed in a tangy Dijon maple glaze, alongside sweet potato cubes and fresh Brussels sprouts that roast until crispy and caramelized.
Why This Dinner Belongs on Your Weekly Rotation
- 15 Minutes of Real Prep: Chop the vegetables, whisk the 4-ingredient glaze in a small bowl, and let the oven do the heavy lifting.
- True One-Pan Cleanup: The chicken roasts right alongside the vegetables, so you only wash one sheet pan and a mixing bowl.
- Naturally Balanced: Packed with lean protein from the chicken, complex carbs from sweet potatoes, and fiber from Brussels sprouts.
- Gluten-Free & Dairy-Free: Wholesome, comforting food that works naturally for sensitive eaters without special substitute ingredients.
The Secret to Crispy Sheet Pan Dinners
The biggest mistake with sheet pan meals is overcrowding the pan. When chicken and vegetables are piled on top of each other, they trap steam and turn soft instead of roasting.
Here are the three rules that guarantee golden chicken skin and crispy vegetables every single time:
- Use an unlined metal pan: While parchment paper makes cleanup fast, putting the halved Brussels sprouts cut-side down directly on the hot metal baking sheet creates those irresistible, deeply browned edges.
- Give the chicken breathing room: Spread the Brussels sprouts and sweet potatoes across the pan first, then nudge them aside to create four dedicated pockets for the chicken thighs.
- Glaze in two stages: Brush half the glaze onto the chicken before it goes into the oven. Spoon the rest over the chicken during the last 12 to 15 minutes of roasting so the maple sugars caramelize into a glossy coating without burning.
Ingredients You’ll Need
- Chicken Thighs: Bone-in, skin-on thighs stay juicy throughout the 35-minute roast and render flavorful pan drippings that season the vegetables below.
- Brussels Sprouts: Trim the stem end and slice them in half lengthwise. Look for firm, bright green heads that are relatively uniform in size.
- Sweet Potatoes: Peel and cut into 3/4-inch cubes so they finish roasting at the exact same moment the chicken is cooked through.
- Whole-Grain Dijon Mustard: Whole mustard seeds give the glaze a wonderful texture and sharp, rustic bite. You can also mix half whole-grain and half smooth Dijon.
- Pure Maple Syrup: Real Grade A amber maple syrup brings rich woodsy sweetness. Avoid artificial pancake syrup, which burns too quickly under high heat.
- Apple Cider Vinegar: A quick splash balances the sweet maple syrup and rich chicken juices with bright acidity.
- Fresh Thyme & Garlic: Fresh thyme leaves pair naturally with roasted poultry and root vegetables.
Temperature & Doneness
Always use a simple instant-read meat thermometer to check your chicken. Insert the probe into the thickest part of the thigh without hitting the bone.
Poultry is safe at 165°F (74°C) according to USDA guidelines, but bone-in dark meat chicken thighs are even more tender and flavorful when cooked closer to 175°F to 180°F (79°C–82°C). At this temperature, the collagen melts down into rich gelatin, leaving the meat tender and pull-apart juicy.
How to Make It (Step-by-Step)
Step 1: Prep the Oven and Pan
Preheat your oven to 425°F (220°C) with the rack set in the middle position. Lightly rub your 18x13-inch rimmed baking sheet with olive oil.
Step 2: Whisk the Glaze
In a small bowl, whisk together the whole-grain Dijon mustard, maple syrup, apple cider vinegar, minced garlic, 1 tablespoon of olive oil, salt, and freshly cracked black pepper until smooth and glossy.
Step 3: Season the Vegetables
Toss the halved Brussels sprouts and sweet potato cubes with the remaining olive oil, thyme leaves, and a pinch of salt. Spread them across the pan, leaving four open spaces for the chicken.
Step 4: Season and Glaze the Chicken
Pat the chicken thighs dry with a paper towel. Season lightly with salt and pepper, then brush half of the maple-mustard glaze over both sides. Nestle the thighs skin-side up into the open pockets on the sheet pan.
Step 5: Roast to Golden Perfection
Roast for 20 minutes. Pull the pan out briefly to spoon the remaining glaze over the chicken skin. Return to the oven for another 12 to 15 minutes, until the chicken registers 165°F–175°F and the sprouts have crispy charred edges. Let the chicken rest for 5 minutes before serving so the juices settle.
What to Serve With This
Because this sheet pan recipe already includes protein, roasted greens, and sweet potato starches, it is practically a complete dinner right off the tray. If you want to round out the meal for company:
- Crisp Green Salad: A simple bowl of arugula or butter lettuce with lemon vinaigrette cuts through the rich glaze.
- Warm Crusty Bread: Great for scooping up the caramelized maple mustard pan drippings.
- Fluffy Grains: Serve over warm brown rice, farro, or quinoa to catch every drop of sauce.
Storage and Reheating
- In the Fridge: Store leftovers in an airtight container for up to 4 days.
- Best Way to Reheat: Skip the microwave, which turns roasted skin soggy. Warm leftovers on a baking sheet in a 375°F (190°C) oven for 10 minutes (or in an air fryer at 360°F for 4 minutes) until the chicken skin crisps up and the sweet potatoes are heated through.
Frequently Asked Questions
Can I make this with chicken breasts?
Yes. Boneless chicken breasts cook faster than bone-in thighs (about 18 to 20 minutes). Roast the sweet potatoes and Brussels sprouts for 15 minutes first, then add the glazed chicken breasts to the pan and roast for the remaining 18 minutes until they reach 165°F.
Can I prep the ingredients ahead of time?
Definitely. Chop the sweet potatoes and trim the Brussels sprouts up to 2 days in advance and keep them in airtight bags in the fridge. You can also mix the glaze in a jar ahead of time. When you are ready for dinner, toss everything on the pan and roast.
Can I swap the maple syrup for honey?
Yes, honey works nicely in a 1:1 ratio. Because honey has slightly more sugar than maple syrup, keep an eye on it during the last 5 minutes so it doesn’t brown too quickly.

Ingredients
Instructions
- Preheat oven to 425°F (220°C). Position the oven rack in the middle. Lightly oil a standard 18x13-inch heavy rimmed baking sheet.
- In a small glass bowl, whisk together the whole-grain Dijon mustard, pure maple syrup, apple cider vinegar, minced garlic, 1 tablespoon olive oil, 1/2 teaspoon salt, and black pepper until emulsified into a glossy glaze.
- In a large mixing bowl, toss the halved Brussels sprouts and cubed sweet potatoes with the remaining 1 tablespoon olive oil, thyme leaves, and remaining 1/2 teaspoon salt until evenly coated. Spread the vegetables across the baking sheet, leaving four clear pockets for the chicken.
- Season the chicken thighs lightly with salt and pepper, then brush half of the maple mustard glaze thoroughly over both sides of each thigh. Place the chicken skin-side up into the reserved spots on the baking sheet.
- Roast for 30 to 35 minutes without crowding. At the 20-minute mark, spoon the remaining glaze over the top of the chicken skin. Continue roasting until the Brussels sprout leaves are deeply charred at the edges, sweet potatoes are fork-tender, and an instant-read thermometer inserted into the thickest part of the chicken registers 165°F (74°C). Rest for 5 minutes before serving.

Frequently asked questions
Can I use boneless, skinless chicken breasts instead?
Yes. Use 1.25 lbs of chicken breasts cut into 1.5-inch cutlets. Because lean breast meat cooks faster than bone-in thighs, roast the sweet potatoes and Brussels sprouts for 15 minutes first, then add the glazed chicken breasts to the pan and roast for the final 15 to 18 minutes until internal temperature reaches 165°F.
How do I ensure the Brussels sprouts get crispy rather than soggy?
Ensure the sprouts are thoroughly dried after washing, roast cut-side down against the hot metal pan, and avoid crowding the sheet pan. If vegetables overlap, they steam instead of roasting.
What style of mustard works best for the glaze?
A coarse, whole-grain Dijon mustard delivers the best textural crunch and balanced acidity. Smooth yellow mustard is too acidic and lacks body, while sweet honey mustard makes the glaze burn too quickly under high heat.
Can I prep this sheet pan meal ahead of time?
Yes. Chop the sweet potatoes and trim the Brussels sprouts up to 48 hours in advance and store them dry in an airtight container. Whisk the glaze together and store in a jar. On dinner night, toss and roast in 35 minutes.
