Preheat oven to 400 degrees F.
Clean and trim Brussels sprouts.
Finely chop 1 shallot.
In a medium-sized bowl add Brussels sprouts, olive oil, salt, pepper and shallot. Mix together.
Pour onto a baking sheet and spread evenly.
Bake uncovered for 20 minutes. Then rotate and flip the sprouts and bake for another 10-15 minutes. * Rotating and flipping helps them brown evenly so they are crispy on the outside and tender on the inside.
Take out the pan and put the brussels sprouts into a medium-sized bowl.
In your Brussels sprouts bowl, add the aged balsamic vinegar and chopped nuts. Mix.
Check for seasoning and serve!
Don't forget that you can bake your Brussels sprouts and cauliflower at the same time. So check out the recipe for "Roasted Cauliflower with Lemon" below!
