If using fresh beans: Bring a large pot of salted water to a boil. Pre-cook green beans for 2 minutes, then soak them in ice-cold water. Drain very well and pat dry with a paper towel.
If using frozen beans: Place the frozen beans in a microwave-safe container. Add ¼ cup of water and cover with a (microwave-safe) lid. Microwave for 45 sec to 1 min, until green beans are thawed. Remove from the microwave. The beans should be thawed but not hot. Drain very well and pat dry with a paper towel.
Preheat the oven to 425 F and line an extra-large baking sheet with parchment paper. Add in the beans.
Pour the olive oil over the beans, add the garlic, seasonings, Parmesan cheese, and toss well to combine; Arrange in a single layer.
Bake for 15-20 minutes, or until the green beans are crisp-tender.
Garnish with freshly chopped parsley and serve with lemon wedges.
