Clean eating made in 35 minutes? I say serve it up! This Chicken with Brussels Sprouts and Mustard Sauce is a perfect mid-week dinner where chicken shares center stage. Protein doesn’t always have to be the main attraction, here vegetables and big time flavor are.

Chicken with Brussels Sprouts and Mustard Sauce.

This killer recipe is one I adapted from Cooking Light and is made with some homemade whole grain mustard, which reminds me I need to make a new batch, but that’s another story.

Instead of roasting the vegetables completely on their own I made sure to try and keep this a one pan meal. The potatoes and brussels sprouts get a quick blanching in the microwave to cut down on time, and to say this sauce is delicious would be an understatement.

Here I use frozen chicken tenders from Costco, but feel free to use what ever chicken pieces you prefer. Just remember if using bone in chicken, the cooking time will change. I made this with boneless chicken.

This is a meal that uses fresh seasonal vegetables like butternut squash, red potatoes and brussels sprouts to make this a balanced meal.  The pan roasted chicken gets a dose of apple cider, chicken broth and whole grain mustard to bump up the flavor. I could have the sauce poured over a baked potato alone and be happy.

Plus, this comes together in 35 minutes. Sound good to you? It did us, and it satisfies on the flavor level besides being a simple dish to pull together when time is an issue after a hard day. Enjoy!

    I didn’t have butternut squash and only had dijon mustard and added some honey (1TBS) and also a garlic clove and added a little more broth than what it asked for, since the potatoes soak up the juice so much. Delish! Thank you!

    This is a keeper!! Prepared this recipe today with a one change. I used Dijon mustard instead of the whole grain mustard because that is all I had. It is so delicious and so simple to make! I love cooking with cast iron!

    1. That’s great Carolyn, thanks for coming back and letting me know! So glad you enjoyed this one. 🙂

  3. Kevin,

    We love Brussels Sprouts, so I was excited to see your recipe. I also make my own mustard and am always looking for new ways to use it. The two were a perfect match. My wife raved about the dish. Another outstanding recipe, thanks!

    1. So glad to see you here again Dave! Glad you guys enjoyed it. Isn’t the apple cider and mustard such a great combo in flavor? Have a great day friend.

    So not only am I a huge fan of Brussels sprouts, red potatoes, chicken tenders and butternut squash…I might be an even huger fan of one pot meals. You knocked it out of the park with this one, my friend!

    I can eat Brussels sprouts all year round, and the combo of sprouts and chicken is one of my favorite. Paired with potatoes, butternut squash, and mustard, it’s one great hearty meal. Well done, Kevin!

    1. Thanks Ben! That mustard apple cider sauce is so good, enjoy.
      BTW, thought of you the other day as I used lavender in a spice blend that honestly could just as well be a potpourri. Heavenly aroma and taste. 🙂

  6. This may be dinner tonight, if I can get everything in time, plus have lunch with an old friend. Cooking for kids and in laws for dinner, so I need something that comes out much better than last night’s fail! I’m sure this would do the trick.

        Thank yoy Kevin, I finally made it tonight and we all loved it. It will definitely be. repeat, that mustard and apple juice really adds a nice flavor.

  7. Another chicken dish HIT OUT OF THE PARK! Butternut, Brussels and Chicken – that trio is kick ass in my opinion! However, I love it a TINY BIT MORE with turkey, because it reminds me of Thanksgiving! 😉

    1. Thanks Gigi, I think next time I’m in the mood for this turkey might have to make an appearance! Thanks for the suggestion my dear!
