Preheat your oven to 400 degrees Fahrenheit and move one of the racks to a lower shelf so that its closer to the bottom heating element. This ensures your green beans get that golden-brown layer on them.

Rinse the green beans well and pat them dry with a paper towel or kitchen towel. Place them on a cutting board and trim the ends off. Note: If you bought packaged green beans from the produce section, they are likely already washed and trimmed so you can skip this step.

Spread the green beans on a large baking sheet and drizzle with avocado oil. Use your hands to toss the beans in avocado oil, ensuring they are well coated. Sprinkle with sea salt.

Place the baking sheet on the lower shelf and roast for 20 to 25 minutes, until beans are golden-brown and have reached desired done-ness.

Serve immediately, and enjoy!
