Spread green beans in a single layer on baking sheet. Drizzle with olive oil. Roll the green beans in the olive oil so each one is nicely coated. Liberally salt and pepper. Bake for 15 minutes.
Remove from the oven. Flip green beans. Spread minced garlic and slivered almonds. Place back in the oven and bake for an additional 5 to 7 minutes. (Keep an eye on the almond slivers. You want them browned but not blackened. 7 minutes is the sweet spot for my oven.)
