Instructions
Preheat oven to 400 °F (204 °C).
Line a rimmed baking sheet with parchment paper.
Place potatoes in a large bowl and drizzle with 2 tablespoons of the olive oil and season to taste with salt and pepper; toss to coat. Spread in an even layer over half of the prepared baking sheet. Bake 20 minutes, stirring once halfway through.
Meanwhile, in a large bowl toss together Brussels sprouts, minced garlic, remaining 2 tablespoons of olive oil; season with salt and pepper and toss well to coat.
When potatoes have roasted for 20 minutes, remove from oven and stir. Spread the Brussels sprouts mixture in an even layer on the other half of the baking sheet. Bake 15 minutes.
Remove from oven; sprinkle Parmesan cheese evenly over all; bake 10 to 15 minutes more, or until potatoes and Brussels sprouts have crispy edges. Gently stir to combine vegetables and transfer to serving bowl; sprinkle with more parmesan cheese if desired. Serve hot.
