What’s the difference between green beans and string beans?
Green beans and string beans are basically the same vegetable. Back in the day, “string beans” had a tough string down the seam that needed to be removed before cooking. Nowadays, we mostly just say “green beans” because newer kinds don’t have those strings. So, they’re pretty much the same thing, just with different names.

Ingredients & Substitutions
Here is everything you need to make the best-tasting roasted green beans:
Frozen Green Beans: I recommend using whole or cut green beans for the best texture. Avoid using French cut frozen beans. With French green beans, the thinner green bean will cook faster than the thicker pieces. You can also use fresh green beans instead of frozen. Blanch them before using them for a similar texture.
Light Olive Oil: Virgin olive oil, extra virgin olive oil, avocado oil, vegetable oil, or melted butter can be used instead of light olive oil.
Garlic Powder: Fresh minced garlic can be used as a substitute. Use one clove of fresh garlic for every 1/2 teaspoon of garlic powder.
Italian Seasoning: You can make your Italian seasoning blend using dried herbs such as basil, oregano, thyme, and rosemary. You can also use fresh herbs.
Onion Powder: Finely minced fresh onion or onion flakes can be used instead of onion powder. Use about one tablespoon of minced onion for every teaspoon of onion powder.
Parmesan Cheese: Any hard, grated cheese like Pecorino Romano or Asiago can be used instead of Parmesan cheese. Finely grated parmesan cheese works best. But you can also finely shred it from a block of parmesan cheese using a zesting grater.
Salt: You can use any salt you have on hand, including sea salt, kosher salt or flaky sea salt.
How to Make My Quick Parmesan Garlic Roasted Frozen Green Beans Recipe
Here are easy, step-by-step instructions for the best way to make this green bean simple side dish:
Step 1: Toss the Green Beans
Preheat your oven to 425°F (220°C).
In a large bowl, mix together 2 tablespoons of light olive oil, 2 teaspoons of garlic powder, 1 teaspoon of Italian seasoning, 1 teaspoon of onion powder, 1 teaspoon of salt, and a dash of black pepper.
Add 14 ounces of frozen green beans (being careful to remove any excess ice) to the bowl and toss them in the seasoning mixture until they are well coated. Sprinkle 1/4 cup of grated Parmesan cheese evenly over the green beans.
Spread the green beans out in a single layer on a baking sheet lined with parchment paper.
Step 2: Roast the Green Beans
Roast the green beans in the preheated oven for about 20 minutes, or until they are crispy on the outside and tender on the inside, stirring halfway through cooking.
Serve the roasted green beans hot as a delicious and healthy side dish. Enjoy!
How to Roast Frozen Green Beans in an Air Fryer:
Place the seasoned green beans in the air fryer basket in an even layer.
Cook the green beans in the air fryer for about 10-12 minutes, shaking the basket halfway through cooking, until they are crispy on the outside and tender on the inside.
Sprinkle 1/2 cup of grated Parmesan cheese evenly over the green beans and cook for an additional 1-2 minutes, or until the cheese is melted and bubbly.
Frozen Roasted Green Beans with Garlic and Parmesan Recipe Notes
Green Bean Texture: You do not need to thaw the green beans. Pull them out of the freezer right before they get tossed in the seasoning. For extra crispy green beans, you can adjust the roasting time and cook the green beans for a few minutes longer. Be careful not to overcook them, as they can become mushy and can burn.
Fresh Green Beans: If using fresh green beans, blanch them in boiling water for a few minutes before tossing them in the seasoning mixture and roasting them in the oven.
Seasoning Adjustments: Feel free to adjust the parmesan green beans seasoning quantities to suit your taste. You can also add other herbs and spices, such as red pepper flakes or smoked paprika, for additional flavor.
Serving Suggestions
You can add other ingredients to the green beans before roasting, such as sliced almonds, bacon bits, cherry tomatoes, a drizzle of lemon juice, or some lemon zest, to create different flavor profiles.
