When cooler evenings arrive, simple oven dinners are hard to beat. This Easy Fall Sheet Pan Chicken and Vegetables combines juicy, herb-seasoned chicken with roasted sweet potatoes, Brussels sprouts, carrots, red onion, and crisp apple for a colorful dinner that tastes like fall without requiring hours in the kitchen.

Everything cooks together on one large sheet pan, which means less cleanup and very little hands-on work. The vegetables become caramelized around the edges, the apple adds subtle sweetness, and a maple-Dijon herb mixture brings the entire pan together.

It’s an especially useful recipe for busy weeknights because most of the work is simply chopping, seasoning, and letting the oven do the rest.

Easy Fall Sheet Pan Chicken Dinner

A good sheet pan dinner isn’t just about putting everything on one tray. The ingredients need to finish cooking at roughly the same time.

That’s why the vegetables in this recipe are cut intentionally. Sweet potatoes and carrots are kept relatively small, while Brussels sprouts are halved. The apple is added later so it softens and caramelizes without turning into applesauce.

Boneless chicken thighs work especially well because they stay juicy at the higher temperature needed for beautifully roasted vegetables.

The result is a complete fall dinner with protein, vegetables, and plenty of seasonal flavor—all from one pan.

🛒 Ingredients

Boneless Skinless Chicken Thighs — 1½ lb (680 g)

Chicken thighs stay juicy during high-temperature roasting and are more forgiving than chicken breasts.

Trim away any large pieces of excess fat before cooking.

Sweet Potato — 1 Large

Peel and cut it into approximately ¾-inch cubes. Keeping the pieces relatively small helps them become tender at the same time as the chicken.

Brussels Sprouts — 12 oz (340 g)

Trim the ends and halve them lengthwise.

If some sprouts are especially large, quarter them.

Carrots — 3 Medium

Cut the carrots into approximately ½-inch diagonal pieces.

Red Onion — 1 Medium

Cut into thick wedges so the onion doesn’t burn before the rest of the vegetables finish roasting.

Apple — 1 Large

Use a firm apple such as Honeycrisp, Pink Lady, or Granny Smith.

Cut it into thick wedges and add it partway through roasting.

Olive Oil — 3 Tablespoons

Helps the vegetables caramelize and carries the herbs and seasoning across the entire dish.

Dijon Mustard — 1½ Tablespoons

Adds acidity and savory depth without making the dish taste strongly of mustard.

Pure Maple Syrup — 1 Tablespoon

A small amount complements the sweet potato and apple.

It shouldn’t make the chicken noticeably sweet.

Garlic — 3 Cloves, Minced

Fresh garlic adds savory flavor to the maple-Dijon mixture.

Fresh Rosemary — 1 Teaspoon, Finely Chopped

Rosemary gives the chicken a distinctly cozy fall aroma.

Fresh Thyme Leaves — 1 Teaspoon

Thyme pairs particularly well with chicken, apple, and roasted root vegetables.

Smoked Paprika — 1 Teaspoon

Adds color and a subtle smoky background flavor.

Salt — 1 Teaspoon

Adjust according to taste.

Black Pepper — ½ Teaspoon

Freshly ground pepper works best.

👩‍🍳 How to Make Fall Sheet Pan Chicken and Vegetables

1. Preheat the Oven

Preheat your oven to 425°F (220°C).

Line a large rimmed sheet pan with parchment paper or lightly grease it.

2. Prepare the Sweet Potato

Peel the sweet potato and cut it into roughly ¾-inch cubes.

Try to keep the pieces reasonably similar in size without worrying about perfect uniformity.

3. Prepare the Brussels Sprouts

Trim the dry ends and remove any damaged outer leaves.

Slice each Brussels sprout in half.

4. Cut the Carrots

Slice the carrots diagonally into approximately ½-inch pieces.

5. Prepare the Onion

Peel the red onion and cut it into thick wedges.

Keep some of the layers together so they don’t burn too quickly.

6. Make the Seasoning Mixture

In a small bowl, whisk together:

• olive oil
• Dijon mustard
• maple syrup
• minced garlic
• rosemary
• thyme
• smoked paprika
• salt
• black pepper

The mixture should look slightly emulsified but doesn’t need to be perfectly smooth.

7. Season the Vegetables

Place the sweet potato, Brussels sprouts, carrots, and red onion on the prepared sheet pan.

Drizzle with approximately half of the seasoning mixture.

Toss until lightly coated.

8. Season the Chicken

Pat the chicken thighs dry with paper towels.

Coat them with the remaining seasoning mixture.

9. Arrange the Sheet Pan

Nestle the chicken thighs between the vegetables.

Avoid piling vegetables underneath the chicken because they will steam instead of roast.

Leave a little space between ingredients wherever possible.

10. Begin Roasting

Transfer the sheet pan to the oven.

Roast for 15 minutes.

11. Prepare the Apple

While the pan roasts, core the apple and cut it into thick wedges.

There’s no need to peel it.

12. Turn the Vegetables

Remove the pan carefully.

Use a spatula to turn the vegetables so additional surfaces can brown.

13. Add the Apple

Scatter the apple wedges throughout the pan.

Keep them in a single layer where possible.

14. Return to the Oven

Roast for another 10–15 minutes.

15. Check the Chicken

The thickest part of the chicken should reach at least 165°F (74°C) internally.

Cooking time can vary according to the size of the thighs.

16. Check the Vegetables

The sweet potato and carrots should be tender when pierced with a fork.

The Brussels sprouts should have browned edges, and the apples should be tender while still holding their shape.

17. Optional Final Browning

If the chicken is cooked but you’d like additional browning, broil the sheet pan briefly for 1–2 minutes.

Watch it constantly.

18. Rest

Allow the chicken to rest for approximately 5 minutes before serving.

19. Finish With Herbs

Scatter a little additional fresh thyme or finely chopped rosemary over the pan if desired.

20. Serve

Divide the chicken and roasted vegetables between plates and spoon any flavorful pan juices over the top.

🍳 Equipment

You’ll need a large rimmed sheet pan, parchment paper, chef’s knife, cutting board, small mixing bowl, whisk, silicone spatula or turner, measuring spoons, and an instant-read meat thermometer.

Using a sufficiently large pan matters. If everything is crowded together, the vegetables release moisture and steam instead of developing those caramelized roasted edges.

🔄 Variations

Butternut Squash

Replace the sweet potato with peeled, cubed butternut squash for an even more autumnal version.

Chicken Breast

Boneless chicken breasts can work, but cooking time will depend heavily on thickness. Use a thermometer and remove them once they reach a safe internal temperature.

Pear Instead of Apple

A firm pear can replace the apple for a slightly different seasonal sweetness.

Add Pecans

Scatter toasted pecans over the finished sheet pan for crunch.

Make It Spicier

Add ¼–½ teaspoon crushed red pepper flakes to the seasoning mixture.

Add Cranberries

A small handful of dried cranberries scattered over the finished dish adds sweetness and color.

💡 Pro Tips

Don’t overcrowd the pan. Use your largest sheet pan so the ingredients roast instead of steam.

Cut dense vegetables smaller. Sweet potatoes and carrots take longer to soften than onions and apples.

Add the apple later. If it roasts for the entire cooking time, it may become excessively soft.

Dry the chicken first. Removing surface moisture helps it brown.

Use a thermometer. Chicken size varies, so temperature is more reliable than appearance alone.

Put Brussels sprouts cut-side down. This gives them better caramelization.

Don’t overdo the maple syrup. We’re making a savory chicken dinner with a touch of fall sweetness, not candied vegetables.

🧊 Storage & Reheating

Allow leftovers to cool before transferring them to an airtight container.

Refrigerate for up to 3–4 days.

For the best texture, reheat the chicken and vegetables in a 375°F (190°C) oven until hot. An air fryer also works well for smaller portions.

The microwave is convenient, although the roasted vegetables will become softer.

You can freeze the cooked chicken and vegetables, but the apple and Brussels sprouts will lose some of their original texture after thawing. For that reason, this recipe is best enjoyed fresh or refrigerated rather than frozen.

❓ Frequently Asked Questions

Can I Prepare This Ahead?

Yes. Chop the sweet potato, Brussels sprouts, carrots, and onion ahead of time and refrigerate them in airtight containers.

The apple is best sliced shortly before adding it to the pan.

Can I Use Chicken Breasts?

Yes, but breasts can dry out more easily than thighs.

Check their internal temperature early and adjust the cooking time according to their thickness.

Why Aren’t My Vegetables Browning?

The most common cause is overcrowding.

Moisture becomes trapped when ingredients are packed tightly together, causing them to steam.

Do I Need to Peel the Apple?

No. Leaving the skin on helps the wedges hold their shape and adds color.

What Apples Are Best?

Choose a firm apple that holds up to heat, such as Honeycrisp, Pink Lady, or Granny Smith.

Can I Use Frozen Vegetables?

Fresh vegetables work much better here because frozen vegetables release additional water during roasting.

Can I Make It Without Maple Syrup?

Yes. Simply omit it or replace it with a small amount of honey.

🍽️ What to Serve With It

This recipe is already a complete dinner, so it doesn’t require much on the side.

A simple green salad works particularly well if you want something fresh alongside the roasted vegetables.

Warm crusty bread is another good option because it can soak up the maple-Dijon pan juices.

For a larger autumn dinner, serve it alongside roasted squash, wild rice, or a simple fall salad with apples and pecans.

And if you’re planning a full seasonal meal, a pumpkin or apple dessert makes a natural finish.
