This fall harvest bake with maple mustard sauce is so cozy! It has butternut squash, brussels sprouts, apples and walnuts all baked to perfection.

Sheet pan butternut squash, brussels sprouts, apples and walnuts with maple mustard sauce

Butternut squash, brussels sprouts, and apple all scream fall to me. The flavors are so comforting. Especially when you add maple syrup and cinnamon. However, I also wanted to add some savory flavors to this side dish. So I figured mustard would be a great place to start. I love the combination of dijon and maple syrup! This sauce drizzled on some roasted veggies is heavenly.

This recipe is very similar to my air fryer maple bourbon Brussels sprouts and squash. The flavors are a little bit different. However, they’re both such comforting recipes! Either of these would be great for Thanksgiving dinner.

I recommend using a good quality dijon for this recipe. It will make all the difference! I really like Sir Kensington’s brand. I’ve loved all of their condiments for years now. But, feel free to use your personal favorite.
