Want to know my secret for delicious roasted green beans with garlic? This oven roasted green beans recipe. I’ll show you just how to roast green beans with parmesan with my double roast method for maximum garlic and parmesan flavor… without burning the garlic.
These roasted haricots verts (that’s green beans in French!) make a great side dish for just about anything, because the flavors are so versatile. You’ll love how easy they come together and everyone else will love how delicious they are!
Can You Roast Green Beans?
Yes, you can absolutely roast green beans in the oven. I’ll show you the best way to cook fresh green beans in oven. And, (spoiler) it’s beyond easy! Which is just one of the reasons why I love these so much. 🙂
This roasted green beans recipe turns out perfectly cooked, and full of flavor from the roasted garlic and parmesan.
Oh, and you can use this method for roasted French green beans (haricot vert) or American green bean varieties. (There isn’t too much difference between the two – just the thickness.)

How To Roast Green Beans With Parmesan
Let’s get onto the important piece – how to roast green beans in the oven! Cooking green beans in the oven is simple, takes minimal prep, and turns out perfectly each and every time.
Let me show you how to bake green beans:
- Trim the green beans. Most people don’t like the stem ends, so trim those off.
TIP: Cut off the ends diagonally. This exposes more surface area, which means they cook a bit faster and absorb a bit more oil.
- Season green beans. In a large bowl, toss together the green beans, olive oil, garlic powder, sea salt, and black pepper. You want to make sure they all get a good coating of oil and seasoning. Spread them out on a sheet pan in a single layer.
TIP: Each green bean should be touching the pan. This helps them cook evenly, and get nice and browned!
- Roast for 20 minutes. Roasting green beans on their own first allows them to cook through, without risk of burning garlic and parmesan, which would happen if we added them right away.
- Prep garlic. While the green beans are roasting, thinly slice the garlic. Toss it with some olive oil, too.
- Add garlic and parmesan to the oven roasted fresh green beans. Sprinkle the garlic and parmesan onto baked green beans. Toss to coat everything.
- Roast again. Continue roasting the baked garlic green beans until they are soft and puckered, and garlic and parmesan are golden brown.
How Long Do You Roast Green Beans?
Wondering how long to roast green beans? I like my roasted green beans with garlic to be nice and golden, so I double roast them! (Don’t worry, it doesn’t add to the total time.)
Total cooking time for this roasted green beans recipe is about 25-30 minutes:
- The first roasting time takes about 20 minutes.
- Add the garlic and parmesan and roast for an additional 6-10 minutes.
If I added the garlic and parmesan for the initial roast, they would burn. This method allows the oven roasted green beans to be perfectly soft and tender, and the garlic and parmesan to turn perfectly golden.
TIP: If you like your green beans a little crispier, reduce the initial roasting to 9-14 minutes, then add the garlic and parmesan and roast for 6-10 more minutes, for a total of 15-20 minutes.
Can You Make Oven Roasted Green Beans Ahead?
Yes, there are a couple ways to make oven roasted green beans with parmesan ahead of time:
- Option 1: Cook green beans completely and then reheat once you’re ready to eat.
- Option 2: Cook the beans partially (the first roasting step), but don’t cook with the garlic and parmesan. Right before serving, toss the partially cooked green beans with the garlic and parmesan, and roast until hot and golden brown.
I prefer the second method since it tastes fresh, but the first one is perfectly fine for leftovers!
Can You Freeze Roasted Green Beans?
Yes, you can freeze pan roasted green beans. Just like the make-ahead green beans, you have two options for roasted frozen green beans:
Option 1: This is the preferred method for roasted frozen green beans. Partially roast them using the method above (~15 minutes) without the garlic or parmesan, then freeze on parchment paper in a single layer. Once solid, you can move them to a freezer bag.
To finish roasting frozen green beans, arrange them in a single layer again on a sheet pan. Roast for about 5-10 minutes, until they are warm, then add the garlic and parmesan, and finish roasting 6-10 minutes, until everything is golden brown.
Option 2: Freeze already roasted green beans. This is not ideal because the texture can get a bit mushy when you reheat them, but is better than wasting food. (I’ve done it with leftovers when I knew we wouldn’t eat them.)
If the beans were already fully cooked, you can simply thaw and reheat afterward in the oven or microwave. If you reheat in the oven, use a lower temperature (325 degrees F) if you had added garlic, otherwise it will burn.
