Tips for the best oven Roasted Green Beans
These oven-roasted green beans are pretty forgiving, but these simple tips will help them brown nicely without getting soft or soggy.
- Dry them well: Excess moisture makes the green beans steam instead of roast.
- Give them some room: Spread the beans in a single layer so they can actually brown.
- Use a bare sheet pan: Direct contact with the hot pan gives you better browning than parchment.
- Finish with lemon: Add the lemon after roasting so the flavor stays fresh and bright.
