Preheat an oven to 350 degrees and line a sheet tray with parchment paper. Rinse and pat dry fresh green beans and place them in a large mixing bowl. If necessary, cut off any hard or stringy ends of the green beans before you use them. Melt the butter in your microwave and drizzle it over the green beans. Toss the green beans with the butter until they’re completely coated. Then, toss the green beans with salt, pepper, and garlic powder.
Step 2
Fill a large Ziploc bag with grated parmesan cheese. You can add a little extra cheese than what is listed to the bag to ensure the green beans get properly coated. Transfer the seasoned green beans to the parmesan cheese bag and seal the bag with air inside. Shake the green beans around until they’re mostly coated in the parmesan cheese. Shake the green beans out onto your sheet tray.
Step 3
Spread the green beans out gently so they bake evenly. Bake the tray in your oven for 25 minutes. Then, flip and move the green beans around on the tray with a fork or other utensil so any remaining white parmesan cheese can brown. Bake the tray for an additional 10 minutes. The green beans should be crispy and easy to pick up. Serve hot!
