Preheat the oven to 400°F. Line a baking sheet with parchment paper and set aside. Wash and slice the bottoms off of 2 lbs Brussels sprouts. Peel off the outer layer of each one, then slice them in half.
In a large bowl, mix together ¾ cup freshly grated parmesan cheese, 3 tablespoon olive oil, 4 minced garlic cloves, 1 teaspoon salt, and ½ teaspoon ground black pepper.
Add the 2 lbs Brussels Sprouts to the large bowl and toss with the parmesan mixture until they’re evenly coated.
Spread the Brussels sprouts on the baking sheet in a single layer. Bake for 30-35 minutes, or until the edges are crispy and the insides are tender when poked with a fork. Use a spatula to scoop everything onto a plate to serve.
