  • 1 pound green beans, trimmed
  • 2 Tbsp olive oil
  • 2 large cloves garlic, minced
  • Salt + pepper, to taste

Directions

Let’s get roasting! Here’s how:

  1. Preheat your oven to 400°F. Line a large baking sheet with parchment paper.
  2. Place the green beans on the baking sheet. Toss them in olive oil, minced garlic, salt, and pepper. Make sure they’re well coated!

  5. Bake in the oven for about 20 minutes, or until lightly browned and the cheese is melted and slightly crispy. You want them fork-tender with a slight crunch—nobody likes mushy green beans!
