Oven-roasted parmesan green beans are a delicious and healthy side dish that is easy to prepare and packed with flavor. This dish is perfect for those looking to add some variety to their vesgetable dishes, and it’s a great way to incorporate more greens into your diet. Here’s how to make oven-roasted parmesan green beans.

What is the difference between a green bean and a string bean?

Green bean and string bean are two different names for the same vegetable. The long, thin, and green pods of this vegetable are commonly referred to as green beans in the United States and Canada, while in some other countries, such as the United Kingdom, they are referred to as string beans.

In the past, many varieties of green beans had a “string” running along the seam of the pod, which needed to be removed before cooking. This is why the term “string bean” was used to refer to this vegetable. However, most modern varieties of green beans have been bred to be “stringless,” meaning that the string is no longer present or is very minimal, making them easier to prepare and eat.

Overall, the difference between green beans and string beans is mostly regional and historical. Nowadays, both terms are used interchangeably to describe the same vegetable.

How To Roast Parmesan Green Beans

Roasting green beans is quite simple!

  • Toss fresh green beans with a small amount of olive oil and season with parmesan, salt, pepper and garlic powder.
  • Spread the green beans in an even layer on a lightly greased baking sheet.
  • Cook on high (425 degrees F), making sure to stir/turn them about halfway through.
PRO TIPS – Don’t overcrowd the beans! Try to put a little space between the beans so they don’t steam while roasting.

Can I Roast Frozen Green Beans?

While fresh green beans are typically recommended for roasting, you can also roast frozen green beans. However, there are a few things to keep in mind to ensure that they turn out well.

First, it’s important to thaw the frozen green beans before roasting them. This can be done by leaving them in the refrigerator overnight or by placing them in a colander and rinsing them under cold water until they are thawed. If you skip this step, the green beans may not cook evenly.

Second, frozen green beans may release more moisture when roasted than fresh parmesan green beans. To prevent them from getting soggy, it’s important to spread them out in a single layer on the baking sheet and pat them dry with a paper towel before roasting.

Lastly, you may need to adjust the roasting time for frozen parmesan green beans. They may take a bit longer to roast than fresh green beans, so keep an eye on them and adjust the cooking time as needed.

Overall, while fresh green beans are ideal for roasting, you can definitely roast frozen green beans with a little extra care and attention to ensure that they turn out delicious.

How do you make crispy green beans?

Making crispy green beans is easy and can be done by following these simple steps:

  1. Start by washing and trimming the green beans, and then pat them dry with a paper towel.
  2. Preheat the oven to 425°F (220°C) and line a large baking sheet with parchment paper.
  3. In a large mixing bowl, toss the green beans with 1-2 tablespoons of olive oil until they are evenly coated.
  4. Season the green beans with your favorite seasonings, such as garlic powder, salt, and black pepper.
  5. Spread the green beans in a single layer on the baking sheet, making sure they are not overcrowded. This will allow them to crisp up better.
  6. Roast the green beans in the preheated oven for 15-20 minutes, or until they are tender and slightly browned.
  7. If you want them even crispier, turn on the broiler and broil them for 1-2 minutes until they are golden brown and crispy.
  8. Remove the baking sheet from the oven and let the green beans cool for a few minutes before serving.


  • Make sure the green beans are dry before tossing them in oil to prevent steaming.
  • Do not overcrowd the baking sheet, as this will cause the green beans to steam rather than roast, making them less crispy.
  • You can also try using a wire rack over the baking sheet to allow for even more air circulation and to prevent the green beans from sitting in their own moisture.
  • Try adding some grated Parmesan cheese, chopped nuts, or breadcrumbs before roasting for extra flavor and crunch.

By following these simple steps and tips, you can easily make crispy and delicious green beans that everyone will love!
