Roasted Parmesan Green Beans: Ingredients and Substitutions
There are only 6 ingredients in this roasted green bean recipe, so let's chat about them and possible substitutions!
- Fresh Green Beans. You can use frozen green beans instead of fresh, just follow one of the two methods I laid out in the recipe card (thawing or roasting from frozen). You can use regular or french green beans! I do not recommend using canned green beans in this recipe.
- Olive Oil. Any neutral oil tastes great in this recipe. My recommendations are olive oil or avocado oil.
- Sea Salt. Feel free to use a delicious flavored salt to make these parmesan green beans (garlic salt, onion salt, etc.)
- Parmesan Cheese. I recommend using a finely grated parmesan cheese (powder-like) in this parmesan green beans recipe. It coats the beans so nicely and browns really well. You can add a sprinkle of the larger shreds for presentation if you like!
How to make Parmesan Green Beans
We're going to dive right into this roasted green bean recipe and walk through the process step-by-step, and don't forget to watch the video.
How to wash fresh green beans
Washing fresh green beans for this parmesan green bean recipe is super easy...
- First, remove the ends from the beans. I prefer to roast green beans without the ends attached because the ends usually become chewy in the roasting process. Either line up a handful of beans and cut the ends off, or snap the ends off by hand (a great task to have your kids help with)!
- Place trimmed green beans into a colander. Put the trimmed green beans in a colander as you go!
- Rinse the green beans. Once you have removed all the ends and the green beans are in the colander, rinse them with cool water. Be sure to toss the beans as you rinse them so they all get washed.
- Let the beans dry. I usually do this whole trimming/washing process sometime in the morning, long before I plan on making these roasted parmesan green beans so they have time to dry. If you're in a hurry you can turn the wet beans out onto a clean kitchen towel or paper towels and pat them dry.
Coat with Olive Oil & Spices
Once the green beans are washed and/or thawed and mostly dry, put them in a large bowl and add some (but not all) of the other ingredients.
Start by adding everything except for the parmesan cheese. Wait until the second roast to add the parmesan cheese because if it's added in the beginning, it will burn before the green beans are fully cooked.
So, in a large bowl toss the green beans with olive oil, sea salt, garlic powder, and pepper and stir until completely combined.
First Roast
After everything is combined, spread the green beans out in an even layer on a greased baking sheet. It's important that they do not overlap so that they all brown evenly!
Bake the green beans in the preheated oven for 10 minutes. They will turn bright green and will be a little softer to the touch than they were before roasting, but they shouldn't be browned yet.
Add Parmesan Cheese
After 10 minutes, remove the slightly roasted green beans from the oven and add the parmesan cheese.
Sprinkle the parmesan cheese all over the green beans and stir them with a spatula to make sure that it is evenly distributed. I recommend using a spatula to use it to lift any oil/cheese that sticks to the pan up off of the pan and onto the green beans.
Second Roast
Once the parmesan cheese is evenly distributed, put the beans back in the oven and roast again.
Bake the parmesan green beans for about 15-20 minutes more, stirring once halfway through. When you stir the beans, be sure to reincorporate any cheese, oil or spices that made their way to the bottom of the pan back onto the green beans.
The beans are done when the cheese is golden-brown!
Serve
These parmesan green beans are best when they are served immediately, crispy and warm straight from the oven.
Store
However, we usually have and I love to save them to use on salads throughout the week!
- Store the parmesan green beans in an airtight container in the refrigerator for up to 5 days!
- Reheating in the microwave will cause them to lose some of their crispiness after being stored in the refrigerator. To reheat in the oven and restore some crispness, warm them at 350 degrees F until they are warmed through.

The terms, green beans and string beans, are synonyms for the same produce item! When someone says, "Green beans they are usually referring to the most common variety, is called Blue Lake Green Beans. Blue Lakes are the classic green bean and are also referred to as string beans.
There is a type of green bean called Haricot vert, which is also known as French beans. These beans are a thinner, shorter and shorter than Blue Lake beans, which means they are more tender and take less time to cook. French beans are commonly sold frozen.

I am giving this a 5, I made it with frozen beans and want to try it with fresh next time....still. super quick and so tasty. I never would have thought to roast green beans with parmesan but it is probably going to become a weeknight staple since even the baby liked it!
Karen R.
Will this recipe travel & reheat reasonably well? Thanks
Laura
Hey Karen...honestly these beans are best when they are served right after roasting. If they are left too long sometimes they loose their crispiness and get soggy!
Karen
Just wondering if the roasted beans will travel & reheat reasonably well. Thanks
Brittany
So easy and delicious 😋
Laura
So glad you enjoyed them Brittany!
judy Herington
this recipe looks wonderful.
do you think the haricot vert type of bean would work? less cooking time?
Laura
They would work great! And yes I'd watch them because they may cook faster!
