Wash potatoes and green beans, slice potatoes into 1 inch quarters and snip any stems off of ends of green beans.
Place on a large baking sheet and drizzle with olive oil and minced garlic. Toss with spoons or hands to coat the veggies in olive oil.
In a small bowl combine salt, pepper, onion powder, and parsley.
Sprinkle seasonings over all veggies, tossing to coat them evenly.
Bake for 35-40 minutes, make sure to take the veggies out at the 20 minute mark to stir them, then place them back in the oven for the last 15-20 minutes. Test with a fork for doneness.
Notes
Note: If using frozen green beans, make sure to thaw completely before baking, otherwise they won't be properly cooked. Refrigerate for up to 5 days. Freeze for up to 3 months.
