These oven-roasted green bean chips turn a humble vegetable into an addictively crunchy, savory snack. Dusted with parmesan and warm spices, they deliver the satisfying crunch of a chip with a fraction of the carbs.
Ingredients
- 1 lb fresh green beans, trimmed and patted dry
- 2 tbsp olive oil
- 1/3 cup grated parmesan cheese
- 1/2 tsp garlic powder
- 1/2 tsp onion powder
- 1/2 tsp smoked paprika
- 1/2 tsp salt
- 1/4 tsp black pepper
Instructions
- 1
Preheat the oven to 425°F and line two large baking sheets with parchment paper.
- 2
In a large bowl, toss the trimmed green beans with the olive oil until evenly coated.
- 3
In a small bowl, stir together the parmesan, garlic powder, onion powder, smoked paprika, salt, and pepper. Sprinkle the mixture over the beans and toss again so every bean is dusted.
- 4
Spread the beans in a single layer across both sheets, making sure they don't overlap — crowding steams them instead of crisping them.
- 5
Roast for 18–22 minutes, rotating the pans halfway through, until the beans are shriveled, browned at the edges, and crisp. Let cool 5 minutes on the pan to firm up, then serve.
Tips & notes
- Drying the beans thoroughly is the secret to crunch — any surface moisture turns to steam and leaves them soft.
- Swap the parmesan for nutritional yeast to make these dairy-free while keeping the savory, cheesy flavor.
- These are best eaten the day they're made; if they soften, re-crisp in a 350°F oven for 5 minutes rather than the microwave.
