How to Make This Recipe
1: Preheat the Oven
Preheat your oven to 425°F and line a baking sheet with parchment paper. This prevents sticking and makes cleanup easier.
2: Prepare the Green Beans
- Wash the fresh green beans and trim the ends.
- Pat them dry completely to ensure they roast properly instead of steaming.
3: Season the Green Beans
- In a large mixing bowl, combine olive oil, onion powder, garlic, salt, black pepper, and shredded parmesan cheese.
- Add the green beans and toss them well to coat evenly.
4: Arrange on the Baking Sheet
- Spread the seasoned green beans out in a single layer on the prepared baking sheet.
- Avoid overcrowding to ensure even cooking and crispiness.

5: Bake the Green Beans
- Place the baking sheet in the preheated oven and bake for 20 minutes.
- Check halfway through and toss the green beans for even roasting.
6: Add the Cheese
- Remove the green beans from the oven and sprinkle them with shredded mozzarella cheese.
- The cheese adds a gooey, melty layer that enhances the flavor.
7: Broil for Extra Crispiness
- Turn the oven to broil and return the green beans for 4-5 minutes.
- Watch closely to prevent burning. The cheese should be golden and bubbly.
8: Serve and Enjoy
- Remove from the oven and let the green beans cool for a couple of minutes.
- Taste and adjust seasoning with additional salt and pepper if needed.
- Serve hot as a delicious low-carb side dish.
