Scatter the trimmed green beans on a baking sheet and drizzle with olive oil. Sprinkle with salt and pepper and scatter the garlic over the green beans.
Place the baking sheet into the oven and roast for 12-15 minutes until the green beans are slightly toasty and tender. Remove the baking sheet from the oven and top with the goat cheese, lemon zest and lemon juice. Adjust salt and pepper as needed and serve immediately
