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.

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.

Refrigeration: Allow the roasted green beans to cool completely before transferring them to an airtight container. Refrigerate them for up to 3 days.

Freezing: While you can freeze roasted green beans, their texture may become mushy when thawed and reheated. If you do freeze them, place them in a single layer on a baking sheet and freeze until solid before transferring them to a freezer-safe container or bag. They can be stored in the freezer for up to 2 months.

Reheating: To reheat refrigerated roasted green beans, place them on a baking sheet and heat them in a 350°F (175°C) oven for about 10 minutes, or until warmed through. For frozen green beans, bake them at 350°F (175°C) for about 15-20 minutes, or until heated through.

Microwaving: You can also reheat small portions of roasted green beans in the microwave. Place them in a microwave-safe dish, cover with a damp paper towel, and microwave on high for 1-2 minutes, or until heated through.

Can I use fresh green beans instead of frozen green beans in this quick recipe?
Yes, you can use fresh whole green beans for this recipe. Simply blanch them in boiling water for a few minutes before tossing them in the seasoning mixture and roasting them in the oven.

Can I use a different type of cheese in this green bean recipe?
Yes, you can use any hard cheese you prefer, such as Pecorino Romano or Asiago, instead of Parmesan cheese.

Can I add other ingredients to the green beans?
Yes, you can add other ingredients such as sliced almonds, bacon bits, or cherry tomatoes before roasting to create different flavor profiles.

Can I adjust the seasoning to suit my taste?
Yes, feel free to adjust the seasoning quantities to suit your taste. You can also add other herbs and spices for additional flavor.

    These were sooo amazing! I have a giant bag of skinny frozen green beans from Costco that I had NO idea what to do with…now I could easily eat the entire bag this way! Thank you for the recipe! My kids loved them as well. Followed your recipe exactly, except I only baked the beans for 13ish minutes because they are super thin, and they were perfect. Will be making again!

    1. Hi Sus, thank you so much for sharing this with me!! I feel the same way 🙂 I was so happy to find a last minute and delicious way to add green beans to our meals that are so easily stored in the freezer!
