Maple Dijon Chicken w/ Roasted Fall Vegetables
Maple Dijon Chicken is one of those dinners that checks all the boxes for me: protein-forward, full of flavor, and cozy without feeling too heavy. I wanted to create a chicken dinner that was just as practical for a busy weeknight as it was something you’d actually look forward to eating—and this one definitely delivers.
The chicken gets coated in a sweet and tangy marinade made with pure maple syrup, Dijon mustard, mustard seeds, apple cider vinegar, garlic, and a few spices, then roasted alongside delicata squash, sweet potatoes, and broccoli. I like to reserve a little of the maple Dijon mixture before marinating the chicken so I can spoon it over everything at the end. That final drizzle brings back all that bright, punchy flavor after roasting and makes the whole dish come together.
It’s colorful, satisfying, packed with protein and vegetables, and a great reminder that a well-rounded dinner definitely doesn’t have to be boring or complicated. Let’s get cookin’!

5 garlic cloves, minced
1 teaspoon mustard seeds
1½ teaspoons smoked paprika
1½ teaspoons dried thyme
¾ teaspoon onion powder
1 teaspoon kosher salt
Freshly ground black pepper
ROASTED VEGGIES
2 medium sweet potatoes, cut into roughly ¾-inch pieces

Instructions
Make the maple Dijon marinade
In a bowl, whisk together the Dijon, mustard seeds, maple syrup, olive oil, apple cider vinegar, soy sauce, garlic, smoked paprika, thyme, onion powder, salt, and a few cracks of black pepper.Before the marinade touches the raw chicken, reserve about 3 tablespoons in a separate bowl. You’ll use this at the very end to finish the dish.
Marinate the chicken
Pat the chicken breasts dry. If your chicken breasts are especially thick or uneven, lightly pound them to a more even thickness so they cook at the same rate.Add the chicken to the remaining maple Dijon marinade and toss until well coated. You can cook the chicken right away or cover and refrigerate it to marinate ahead of time.
Prep the veggies
Preheat the oven to 425°F.Halve the delicata squash lengthwise and scoop out the seeds. Slice the squash into evenly sized half-moons.
Cut the sweet potatoes into pieces that are roughly the same thickness and size as the delicata squash. This is important: because the vegetables are cut to a similar size, they can roast together and finish cooking at roughly the same time.
Cut the broccoli into similarly sized florets.
Set up three sheet pans
Use three separate sheet pans: one for the chicken, one for the delicata squash and sweet potatoes, and one for the broccoli.Giving everything enough room allows moisture to evaporate so the vegetables roast and caramelize rather than steam. It also lets you pull each component from the oven as soon as it’s perfectly cooked instead of overcooking one ingredient while waiting for another.
Roast the squash and sweet potatoes
Add the delicata squash and sweet potatoes to one sheet pan. Drizzle with olive oil and season generously with salt and pepper. Toss to coat and spread everything into an even layer.Because the squash and sweet potatoes have been cut to a similar size and thickness, they can go into the oven at the same time.
Roast at 425°F until tender and golden around the edges, flipping or tossing about halfway through.
Roast the broccoli
On your second vegetable sheet pan, toss the broccoli with olive oil, salt, and pepper. Spread it into an even layer and roast at 425°F until tender with browned, slightly crisp edges.The broccoli will generally cook faster than the squash and sweet potatoes, which is another reason I like keeping it on its own pan—you can simply pull it when it’s ready.
Roast the chicken
Arrange the marinated chicken breasts on the third sheet pan, allowing any excess marinade to drip off before placing them on the pan.Roast at 425°F until the chicken is cooked through and the thickest part reaches 165°F, approximately 16–20 minutes depending on the thickness of your chicken breasts.
Let the chicken rest for about 5 minutes before slicing.
Finish and serve
Arrange the sliced chicken with the roasted delicata squash, sweet potatoes, and broccoli.Spoon the reserved maple Dijon sauce over the chicken and vegetables just before serving. Because this portion of the sauce never touched the raw chicken, it’s safe to use as-is—and adding it at the end brings back the bright, tangy maple Dijon flavor that mellows during roasting.
Make It Ahead
The chicken can be marinated ahead of time and refrigerated until you’re ready to cook. Instead of roasting it, you can also cook the chicken on the grill for a little extra char and smoky flavor.
Boneless, skinless chicken thighs can also be substituted for the chicken breasts; just adjust the cooking time as needed.
Jo’s Tips
Cut for the cook time. Different vegetables can absolutely roast together when you account for how quickly they cook. Cutting the sweet potatoes to roughly the same size and thickness as the delicata squash helps the two finish at the same time.
Give your food room to roast. Overcrowding a sheet pan traps moisture. That moisture creates steam, which makes it harder to develop the golden, caramelized edges you’re looking for. Using separate pans gives the chicken and vegetables enough room for better browning.
Balance sweetness with acid. Maple syrup brings sweetness, while Dijon and apple cider vinegar add acidity and sharpness. That contrast keeps the marinade balanced rather than overly sweet.
Finish with fresh flavor. Reserving some marinade before it touches the raw chicken gives you a fresh finishing sauce. Adding it after roasting brings back some of the brightness and acidity that naturally mellow in the oven.
STORAGE & REHEATING
To store: Let the chicken and roasted vegetables cool completely, then transfer to airtight containers and refrigerate for up to 3–4 days. You can store everything together for easy meal prep or keep the chicken and vegetables separate. Store any leftover maple Dijon sauce separately.
To reheat: For the best texture, reheat the chicken and vegetables in a 375°F oven until warmed through. You can also reheat individual portions in the microwave in 30-second intervals. To help keep the chicken juicy, avoid overheating it.
To serve again: Add a spoonful of the reserved maple Dijon sauce after reheating to bring back that fresh, tangy flavor. If you’re making this specifically for meal prep, consider keeping the finishing sauce separate and adding it just before serving.
