How to make sheet pan dijon mustard chicken thighs and vegetables:

In order for everything to have room to cook on the sheet pan, I recommend you either make this on two separate sheet pans or invest in a half sheet pan (which will fit in most ovens)(affiliate). If you use a half sheet pan, start the pan with just the butternut squash, then add the chicken and brussel sprouts after roasting for about 10 minutes. Everything should be done at the same time!

The butternut squash will take slightly longer to cook than the brussel sprouts and chicken thighs so if you are making this on two separate sheet pans, the butternut squash will go on its own pan and will cook for about 10 minutes before adding the brussel sprouts and dijon mustard chicken thighs.
While the butternut squash is roasting, cut the brussel sprouts in half (or quarters if they are really large). Add the brussel sprouts to one side of a baking sheet and leave the other side for the chicken thighs.
Make the marinade for the dijon mustard chicken thighs and coat the boneless skinless chicken thighs well. Add the chicken thighs to the pan with the brussel sprouts.
Cook the chicken and brussel sprouts in the oven with the butternut squash for about 18 minutes.
After 18 minutes, check the internal temperature of the chicken. If it’s reached 165F, take the chicken thighs off the baking sheet and give the brussel sprouts 3-4 minutes to cook without the chicken to allow any excess liquid from the chicken thighs to cook off.

Can you use chicken breast instead of chicken thighs?

This recipe for dijon mustard sheet pan chicken uses boneless skinless chicken thighs because the chicken thighs are much more forgiving in the oven. Chicken thighs don’t dry out as quickly and don’t get as stringy if they are overcooked.

Yes, you can use chicken breast instead of chicken thighs in this recipe. However, it’s important that you butterfly the chicken breast so that it will cook inadequate time. You can also cut the chicken breast into strips so that it will cook quickly (15-18 minutes in a 450F oven).

One tip to keep the chicken breast from drying out is to cover the chicken with foil for at least part of the cooking.

Tips on easy clean-up for sheet pan meals:

Because you are cooking everything on a sheet pan, using parchment paper to line the sheet pan makes for a simple clean up. If you don’t have parchment paper you could also use aluminum foil or silicone pan liners.

How long will roasted chicken thighs and vegetables last in the fridge:

Roasted chicken is good for about 3 days in the fridge in a sealed container. The vegetables will last about 5 days in the fridge in a sealed container. If you are going to make this sheet pan dijon mustard chicken thighs and vegetables recipe for meal prep, I recommend these glass containers for easy storage!

If you need the chicken to last longer, you can freeze the cooked chicken thighs in individual portions in a zip lock bag with all the air removed. Just defrost and reheat as you normally would.
