Heat your oven to 400°F (200°C) and line a large baking sheet with parchment paper to prevent sticking.
02 -
Spread the trimmed green beans on your prepared baking sheet. Drizzle with olive oil, sprinkle with minced garlic, and season with salt and pepper. Use your hands to toss everything together so the beans are evenly coated, then spread them out in a single layer.
03 -
Sprinkle the freshly grated parmesan all over the green beans, making sure they're evenly covered with that delicious cheese.
04 -
Pop the baking sheet in the oven for about 20 minutes. You're looking for the beans to get slightly browned with the cheese melted and just starting to crisp up. The perfect texture is fork-tender but still with a nice bite to them!
05 -
Take the beans out of the oven and immediately squeeze fresh lemon juice over everything. Scatter the chopped parsley on top and taste - add a bit more salt and pepper if needed. Serve them while they're hot and enjoy!
