Pat the artichoke hearts dry with a paper towel. Toss the artichoke hearts with olive oil, sea salt, and black pepper.
Place the artichoke hearts in a single layer across a parchment or aluminum foil lined, rimmed baking sheet - cut side down. Bake for 20 minutes.
Remove the artichokes from the oven, flip them over and sprinkle on the parmesan cheese. (If using optional minced garlic, combine it with the parmesan cheese before topping artichokes) Bake for an additional 5 minutes.
Place the roasted artichoke hearts on a serving plate and serve immediately.

Notes
Cooking Tips - Make sure to dry every artichoke before you toss it with olive oil. If the artichokes are too wet, the olive oil won't stick, and they won't get crispy in the oven.Storage - Leftovers can be stored in the refrigerator for up to 3 days. Reheat them in the oven or a toaster oven.
