Wash Brussels sprouts, remove any bad exterior leaves, trim bottom stems, and dry thoroughly.
Cut dried sprouts in half and place into large mixing bowl.
Add rough chopped garlic, parmesan cheese, olive oil, salt, and pepper. Toss to evenly distribute all ingredients except the lemon.
Place sprout halves flat side down onto a baking sheet. Add extra olive oil if needed.
Place into a preheated 425° oven for 20 to 30 minutes until Brussel sprouts are cooked through with plenty of crispy bits.
Top with lemon zest and juice. Toss and enjoy!
Notes
Make sure to thoroughly dry the Brussels sprouts to ensure a crispy result. I chop the garlic very roughly, almost chunky, to help prevent any burning. Do not mince it in this case. I always add extra parm at the end. Because, parm.
