Prepare Brussels sprouts, making sure to pat them dry to remove any remaining moisture. Add prepared Brussels sprouts to a large bowl.
In a small bowl, prepare sauce with all remaining ingredients except for parmesan cheese.
Add sauce to sprouts and toss to coat, making sure everything is mixed and coated. Add Parmesan cheese and toss one more time. (See notes for alternative prep methods!)
Place Brussels sprouts in a single layer on a large, rimmed non-stick baking sheet.
Bake at 400 F for 15 mins, remove from oven and toss Brussels sprouts while also making sure to scrape all Parmesan cheese off the bottom of the pan.
Return pan to oven and bake for another 5 minutes, then repeat the toss/scrape process from the previous step.
Optionally return to the oven for another 5 minutes. Your goal is fairly crispy Brussels sprouts without burning the Parmesan.
Serve and enjoy!
Notes
Want the parmesan cheese to melt mostly on the Brussels sprouts rather than allowing some of the cheese to crisp on the baking sheet? Don’t toss the Parmesan with the sprouts; instead, strategically sprinkle it on by hand after you’ve added the sprouts to the baking sheet.
Like your sprouts extra crispy? Bake them for 10 mins first before adding the parmesan cheese. This will allow you to bake the whole dish longer until you achieve the extra crispy sprouts of your dreams!
