A simple, crisp-tender side dish, these roasted Parmesan green beans are packed with savory flavor and require minimal effort. I toss fresh green beans with olive oil, seasonings, and a generous sprinkle of Parmesan cheese before roasting them to golden perfection. The result is a deliciously cheesy and slightly crispy vegetable dish that pairs well with almost any main course.
Why You’ll Love This Recipe
I love how this recipe transforms everyday green beans into something truly special with just a handful of ingredients. It’s easy enough for a weeknight meal but flavorful enough to serve at a dinner party or holiday gathering. Roasting brings out the natural sweetness of the green beans, and the Parmesan adds a deliciously salty crunch on top. Plus, it's vegetarian, gluten-free, and low-carb — making it suitable for a variety of dietary preferences.
ingredients
(Here's a tip: Check out the full list of ingredients and measurements in the recipe card below.)
1½ lb (≈ 680 g) fresh green beans, trimmed
1 tablespoon olive oil
⅓ cup (≈ 35 g) grated Parmesan cheese
1 teaspoon garlic powder
½ teaspoon salt (or to taste)
¼ teaspoon freshly ground black pepper
directions
I preheat the oven to 425 °F (≈ 220 °C) and line a baking sheet with parchment paper or lightly grease it.
In a large bowl, I toss the green beans with olive oil, garlic powder, salt, and black pepper until evenly coated.
Then I spread the beans out in a single layer on the prepared baking sheet.
I roast them for about 15 minutes, then use a spatula to shake or turn them for even cooking.
I sprinkle the grated Parmesan cheese over the top and return the pan to the oven for another 8–10 minutes, until the beans are tender and the cheese is golden and crisp.
I serve them immediately while they’re still warm and delicious.

Variations
There are plenty of ways I like to switch this up:
I sometimes add red pepper flakes for a spicy kick.
A sprinkle of smoked paprika or Italian seasoning gives a whole new flavor profile.
I like to finish with a squeeze of fresh lemon juice to brighten the dish.
Swapping Parmesan for Asiago or Pecorino Romano also works beautifully.
For a heartier version, I toss in toasted almonds
storage/reheating
These green beans are best enjoyed fresh, but I do save leftovers occasionally. I store them in an airtight container in the fridge for up to 3 days. To reheat, I use the oven or toaster oven to bring back their crisp texture. The microwave works in a pinch, but the beans will be much softer and less crisp.
FAQs
How do I keep green beans from getting soggy in the oven?
I make sure the beans are completely dry before tossing with oil and roasting. Moisture can steam the beans instead of crisping them.
Can I use frozen green beans instead of fresh?
Yes, but I thaw and dry them thoroughly first. They won't be quite as crisp as fresh, but they’ll still taste great.
Is it better to use grated or shredded Parmesan?
I always use freshly grated Parmesan for this recipe. It melts and crisps up better than pre-shredded varieties, which often have anti-caking agents.
Can I make this dish ahead of time?
It’s best served fresh, but I can prep everything in advance and pop the beans in the oven right before serving.
What can I serve with roasted Parmesan green beans?
I like to pair them with roast chicken, grilled steak, pasta dishes, or even holiday meals like turkey or ham. They’re a versatile side that works with almost anything.
Conclusion
Roasted Parmesan green beans are one of my go-to side dishes when I want something easy, healthy, and flavorful. With just a few pantry staples and 30 minutes, I can whip up a dish that everyone loves. Whether I’m serving them on a busy weeknight or adding them to a special dinner, these beans never disappoint.
A simple, flavorful side dish of green beans roasted until crisp‑tender, coated with olive oil and topped with savory Parmesan cheese.
Ingredients
1½ lb (≈ 680 g) fresh green beans, trimmed
1 Tbsp olive oil
⅓ cup (≈ 35 g) grated Parmesan cheese
1 tsp garlic powder
½ tsp salt (or to taste)
¼ tsp freshly ground black pepper
Instructions
Preheat your oven to 425 °F (≈ 220 °C). Line a baking sheet with parchment paper or lightly grease it.
In a large bowl, toss the green beans with olive oil, garlic powder, salt, and black pepper until evenly coated.
Spread the green beans in a single layer on the prepared baking sheet.
Bake for about 15 minutes, then use a spatula to turn or shake the pan so the beans roast evenly.
Sprinkle the grated Parmesan cheese over the beans, then return to the oven and roast another 8–10 minutes (or until the beans are tender and the cheese is golden and crisp).
Remove from oven and serve immediately, while still warm.
Notes
Make sure the beans are dry before tossing them so the cheese and oil adhere better.
Use freshly grated Parmesan (not pre‑shredded) for better melting and flavor.
If desired, add a squeeze of lemon juice just before serving to brighten the flavor.
You can add extra seasonings (e.g. smoked paprika, red pepper flakes, fresh herbs) to vary the taste.
Leftovers lose crispness — reheat in oven or toaster oven rather than microwave to maintain texture.
