Place the frozen beans on a baking sheet and drizzle with 2 tablespoons of olive oil. Mix well, then sprinkle with some salt.
Roast frozen green beans for 20 minutes, then take them out of the oven, mix well, and toss with the garlic herb breadcrumb mixture.
Make the seasoned breadcrumbs
While the green beans are baking, melt 1 tablespoon of vegan butter, then add 1/4 teaspoon garlic powder, 1/8 teaspoon onion powder, 1/8 teaspoon salt, 1/2 teaspoon Italian seasoning, 1/2 tablespoon nutritional yeast, 1/4 teaspoon dried parsley, and 1/4 cup of panko bread crumbs. Mix well.
After baking for 20 minutes, take them out of the oven, stir the beans around, and sprinkle with the garlic-herb breadcrumb mixture.
Then bake the green beans for an additional 5-7 minutes, until the breadcrumbs are golden brown and the beans are slightly crispy on the edges.
Notes
I like to use French green beans, which are a little thinner. If you use larger, fatter green beans, they will need a few extra minutes in the oven!
To make these green beans gluten-free, simply use gluten-free breadcrumbs, omit the breadcrumbs, or drizzle with a squeeze of lemon juice.
You can add other vegetables to the sheetpan too, like cauliflower, broccoli, or Brussels sprouts.
Sliced almonds are also delcious with green beans and can be added along with the breadcrumbs or in their place for a gluten free opiton.
