Perfectly tender Roasted Green Beans with Parmesan are a bold, easy side dish with plenty of fresh garlic. Try my trick of pouring melted butter over your roasted green beans, and you won’t want to make them any other way!

Classic Roasted Green Beans – So Easy to Make!

Roasted veggies are all the rage, and honestly it’s no surprise. Roasting is an easy, mostly hands-free cooking method that delivers tons of flavor. Lightly caramelized tender veggies, with hardly any prep? Um, yes, please!

Some of the most popular veggies to roast are root vegetables, but tender veggies also roast up beautifully. They also cook faster, which can be a real bonus on a busy night. These roasted green beans with parmesan cheese, garlic, and butter are some of the best. They have plenty of flavor, not only from the seasonings and garlic, but from the high-heat roast that brings out the best in each bite.

(Looking for other methods of making green beans? No problem – try this recipe for the Best Green Bean Casserole (from scratch!), these easy Sautéed Green Beans with Garlic or my ultra-easy Air Fryer Green Beans.)

The Ingredients You’ll Need

Keeping things simple, this recipe only needs a handful of basic ingredients to be absolutely scrumptious. Here’s the list of what you’ll need:

  • Olive Oil: Extra-virgin olive oil has the most flavor, but any kind is fine. You could also substitute avocado oil.
  • Garlic: Minced or pressed.
  • Seasonings: Onion powder, salt, and pepper.
  • Green Beans: Make sure to wash, dry, and trim the green beans before you start cooking.
  • Parmesan: Freshly grated is best, but pre-grated is also fine.
  • Butter: Melt the butter for drizzling over the beans.

How to Make This Dish

Another thing to love about roasted green beans is that it’s such a hands-off recipe. All you have to do is season the beans, and then let the oven do the rest. Quick and simple.

  • Get Your Oven and Sheet Pan Ready. First things first: preheat your oven to 400°F, and then line a large baking sheet with parchment paper.
  • Coat the Green Beans in the Seasoning Mixture. Next, whisk together the olive oil, garlic, onion powder, salt, and pepper in a big mixing bowl. Dump in the green beans, and toss them around to coat.
  • Top with Cheese and Roast for 10 Minutes. Spread the green beans out on your prepared baking sheet, making a single layer. Sprinkle about half of the parmesan cheese over them, and then bake them for 10 minutes.
  • Add the Melted Butter and More Cheese, and Finish Roasting. Take the green beans out of the oven for a moment, so you can drizzle the melted butter over them. Sprinkle on the rest of the parmesan, and bake for 10 more minutes, or until the beans are tender.
  • Enjoy! Serve these warm, garnished with extra parmesan if desired.

Why Are My Roasted Green Beans Tough?

If you find that your green beans are on the tough side, it’s probably one of three things: the age and size of the beans, undercooking them, or overcooking them.

  • Age and Size: The older the green beans, the tougher they get – this is why older beans are often slow-cooked for a long time. A light roast just isn’t intense enough to tenderize mature, stringy beans.
  • Undercooking: It’s easy to undercook veggies, especially when you’re using a new or different technique. Make sure to cook the green beans a little longer if they’re not quite tender. That could be all you need to do!
  • Overcooking: Although this one isn’t likely, it’s possible to cook the beans until soft and tender, but then keep going and cause them to be slightly burnt and dried out. Make sure to check them and avoid overcooking.

Recipe Tips

While making roasted green beans really is as easy as mixing everything up and baking, there are still some helpful tips for this recipe I’m excited to share:

  • Onion Powder: I like to use onion powder or onion flakes in roasted green beans – it adds a great flavor.
  • Add Tomatoes: For a touch of acidity and textural contrast, try adding some grape or cherry tomatoes to the seasoning mixture and roasting them along with the beans like in my favorite Garlic Roasted Cherry Tomatoes. They will soften and burst a little bit – so yummy.
  • Add Bacon: A little bit of crisply-cooked bacon is the perfect garnish for this recipe. You can cook it and chop it into tiny pieces before sprinkling it over the finished dish.

What to Serve with Green Beans

Roasted green beans are so versatile, and work well with almost any dinner. Here are a few easy ideas for inspiration:

  • Chicken: The sauce on this Baked Honey Mustard Chicken is so addictively sweet, tangy, and savory, you’ll want to make it every week. Or go with my very favorite classic recipe for The Best Baked Chicken.
  • Meatloaf: Why make just a plain meatloaf, when you can top it with a layer of ultra-creamy mashed potatoes? Just add a side of green beans to this Loaded Potato and Meatloaf Casserole, and you’re looking at a crowd-pleasing meal.
  • Hamburger Helper: But not from a box – once you see how easy it is to make your own Homemade Hamburger Helper, this kid-friendly classic is sure to be a go-to weeknight dinner.

Storing and Reheating

To store, place the green beans in an airtight container in the fridge for up to 5 days.

Reheat by baking them again for about 10 minutes. You can also reheat in the microwave, but the green beans won’t have as good a texture that way.

Do Roasted Green Beans Freeze Well?

I don’t recommend storing these in the freezer, because the texture tends to soften up quite a bit from freezing and thawing. 

However, if you really want to freeze roasted green beans for later, you can cool them down and “flash freeze” them in a single layer on a baking sheet. (This should take an hour or so.) Once they’re frozen solid, pack them into a freezer bag and keep frozen for up to 4 months.
