Preheat the oven to 450 degrees F. Place the green beans on a large rimmed baking sheet.
Drizzle the oil over the green beans. Then sprinkle beans with minced garlic, lemon zest, salt and black pepper. Toss to coat.
Spread the green beans out in a single layer. Roast in the oven for 12-15 minutes, or until soft but still slightly firm. Top with toasted almonds.Serve warm.
