Preheat oven to 425°F. Line a large baking sheet with parchment paper.

Wash and thoroughly dry green beans.

Trim any stems from green beans with a knife or kitchen scissors.

In a large bowl, combine vegetable oil, ranch powder, salt, pepper, garlic powder, red pepper flakes, and vinegar. Whisk ingredients until well combined.

Add green beans to bowl and toss in oil mixture until beans are well coated.

Spread prepared green beans on cookie sheet evenly.

Bake in oven for 15 minutes.

TIP: Green beans will still be somewhat crunchy. If a softer texture is desired, turn off oven and allow to sit in closed oven for 10 minutes. This will soften the beans.

Place roasted green beans in serving bowl. Toss with grated parmesan cheese and almonds.

Store leftovers in an airtight container for up to 4 days.
