This chicken with brussels sprouts and sweet potatoes is an easy way to enjoy all the flavors of fall in one dish! Crispy chicken is nestled into a bed of tender veggies with bacon and pecans. It all gets roasted in the oven for a simple, seasonal meal that’s ready in under an hour!

This chicken with Brussels sprouts and sweet potatoes is one of my favorite meals to make once fall settles in. It’s hearty, cozy, and filled with all the flavors I crave as the weather starts to cool and life gets a little busier.
I love how versatile it is, too. It’s simple enough for a weeknight dinner, but it also feels right at home on the table for small gatherings or special occasions, including Thanksgiving.
Ingredients needed
This chicken with brussels sprouts and sweet potatoes is full of feel-good ingredients. Here’s everything you need to make it:
- Bacon: we use regular slices of bacon but you can use a thick-cut variety if you prefer.
- Onion: any type of cooking onion works and will become nice and caramelized as it cooks.
- Bone-in chicken thighs: we use bone-in chicken thighs but you can use boneless if you don’t want to deal with the bones. Snd chicken breasts works, too.
- Sweet potato, brussels sprouts, and apple: this trio of vegetables makes this dish undeniably perfect for fall!
- Toasted pecans: the toasted pecans soften in this dish and add a wonderfully nutty flavor. Walnuts make a great substitute.

Recipe FAQs
Can I add fresh herbs to this dish?
Of course! A sprinkle of fresh herbs, such as thyme, rosemary, oregano, and sage, is a flavorful addition to this dish.
How do I store leftover chicken?
Store any leftover chicken and vegetables in your fridge in an airtight container for 3-4 days.
Can I make it without the bacon?
Yes, you can. If you’re skipping the bacon, cook the onions in a tablespoon of olive oil or butter.
Can I make it on a baking sheet instead of in a casserole dish?
Yep! We like to roast it in a casserole dish because it looks nice for serving, but you can make it a sheet pan meal by using a baking sheet.

This is a solid recipe. Simple and delicious and flavorful. I didn’t have pecans so I used walnuts and it was still great.

That’s great, Lindsay! Thank you for the comment!
This was amazing! I loved it! I made it pretty much like the recipe said, but I used a little more of everything to make 6 servings instead of 4. The grocery store didn’t have organic thigh meat on the bone, so I used boneless instead. I bet bone-in thighs would be better, but the boneless worked just fine. I will be making this several more times this fall. It’s a perfect fall meal.
That’s so wonderful to hear! Hooray!!

This was so delicious! And easy! I doubled the bacon (duh), added dates (duh, subbed butternut squash for the sweet potatoes, and used chicken breast chunks instead of chicken thighs. I even got compliments on how good the leftovers smelled at lunch in the office the next day!
Great recipe! I just finished the whole30 but love eating that way so much Im still pretty much sticking to it. And its so easy with recipes like this! I cut out the brussels and added carrots instead and it was awesome both for dinner and as left overs.
