Roasted Parmesan Green Beans are a simple and tasty way to enjoy fresh green beans with a bit of a cheesy crunch. The beans get tender in the oven, with edges that crisp up just right, while a sprinkle of parmesan cheese adds a nice salty twist. It’s a quick side dish that feels like a small upgrade to everyday veggies.
I love making this because it’s so easy to prepare, and it always gets great feedback from everyone at the table. For a little extra flavor, I like to toss the beans with a drizzle of olive oil and some garlic before roasting—it makes the parmesan stick better and gives the beans a gentle garlic punch. It’s one of those dishes where simple ingredients come together to make something really enjoyable.
This goes perfectly alongside just about any main dish, whether it’s grilled chicken, pasta, or even a casual weeknight burger. I often serve it with a squeeze of lemon on top to brighten everything up. It’s a go-to recipe when I want a healthy side but still want something with a little personality and flavor to it.
Key Ingredients & Substitutions for Roasted Parmesan Green Beans
Green Beans: Fresh green beans work best because they roast to a nice crisp-tender texture. If you can’t find fresh, frozen green beans can be used but roast them for a shorter time to avoid mushiness.
Parmesan Cheese: Parmesan adds a salty, nutty flavor and a crisp topping. Pecorino Romano is a good substitute if you want a sharper taste. For dairy-free, try nutritional yeast for a cheesy hint.
Olive Oil: Olive oil helps the beans roast evenly and keeps them from drying out. You can swap with avocado or sunflower oil if you prefer a neutral taste or have allergies.
Garlic: Garlic is optional but adds great depth. If fresh garlic is too strong for you, garlic powder or roasted garlic can be good milder alternatives.
How Do I Get Crispy, Roasted Green Beans Without Burning the Parmesan?
Getting perfectly roasted green beans with crispy cheese can be tricky. Here’s how I do it:
- Roast the beans first without cheese at a high heat (425°F) until they start to brown and soften, about 15-18 minutes.
- Sprinkle the Parmesan over the hot beans after roasting, then switch your oven to broil for just 2-3 minutes. Keep a close eye so the cheese crisps but doesn’t burn.
- Stir halfway during roasting to brown the beans evenly and avoid burning.
- Using a preheated oven helps create that nice crisp texture on the outside while the insides stay tender.
Equipment You’ll Need
- Baking sheet – perfect for roasting the green beans evenly without crowding them.
- Parchment paper or silicone baking mat – helps prevent sticking and makes cleanup easier.
- Mixing bowl – great for tossing green beans with oil and seasonings.
- Grater – for freshly shredding Parmesan, which melts better and tastes fresher.
- Tongs or spatula – handy for stirring beans halfway through roasting without breaking them.
Flavor Variations & Add-Ins
- Add crushed red pepper flakes for a spicy kick that pairs well with the cheese.
- Stir in toasted sliced almonds after roasting for a crunchy texture contrast.
- Mix in lemon zest with the Parmesan to add a bright, fresh note.
- Swap Parmesan for shaved Pecorino Romano for a bolder, saltier flavor.

How Much Time Will You Need?
This recipe takes about 5 minutes of prep time and around 20 minutes to roast and broil the green beans, so roughly 25 minutes in total from start to finish.
Step-by-Step Instructions:
1. Prepare Your Oven and Baking Sheet:
Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly grease it to prevent sticking.
2. Toss the Green Beans:
In a large bowl, combine the trimmed green beans with olive oil, minced garlic if you’re using it, salt, and freshly ground black pepper. Toss everything together until the beans are evenly coated.
3. Roast the Beans:
Spread the green beans out in a single layer on your prepared baking sheet. Roast them in the preheated oven for 15 to 18 minutes, stirring once halfway through so they cook evenly. You’ll notice they become tender and start to brown.
4. Add Parmesan and Broil:
Carefully remove the baking sheet from the oven, then sprinkle the grated Parmesan cheese evenly over the hot green beans. Return the baking sheet to the oven and switch to the broil setting. Broil for 2 to 3 minutes, watching closely, until the cheese melts and forms a light golden, crispy crust.
5. Serve and Enjoy:
Take the green beans out of the oven and transfer them to a serving dish. If you like, squeeze fresh lemon juice over the top to add a bright finishing touch. Serve warm and enjoy your delicious roasted Parmesan green beans!
Can I Use Frozen Green Beans for This Recipe?
Yes, you can use frozen green beans, but it’s best to thaw and pat them dry first to avoid excess moisture. Roast them for a slightly shorter time to prevent them from becoming mushy.
Can I Make Roasted Parmesan Green Beans Ahead of Time?
Absolutely! You can prepare and roast the green beans a few hours ahead, then reheat in the oven at 350°F for about 5-7 minutes before adding Parmesan and broiling to crisp it up.
How Should I Store Leftovers?
Store leftover green beans in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through, then add a sprinkle of fresh Parmesan if desired.
What Can I Serve with Roasted Parmesan Green Beans?
