Get ready. Preheat your oven to 425°F.
Roast the green beans. In a medium bowl, toss the green beans with enough olive oil to coat (2 to 3 tablespoons) and a big pinch of salt and pepper (1/2 to 3/4 teaspoon). Spread onto a large sheet pan so they’re all in one layer. Roast without moving until the edges are golden brown, 15 to 20 minutes.
Meanwhile, toast the almonds (optional). If you’d like to add a little garnish, heat a drizzle of olive oil in a small pan over medium. Add the almond and toast, tossing until just golden brown, about 5 minutes. As soon as they’re done, pour onto to a plate to avoid burning.
Serve. Transfer the green beans to a serving platter and top with the toasted almonds (if using). Serve warm.
