Expert Tips
- Buy the bags of green beans for easy prep.
- You do not have to boil the green beans before roasting which makes them super easy. Green beans cook through easily without par-boiling.
- Be sure to check them after about 15 minutes to see how they’re cooking. All ovens roast differently!
- You can also cook these in the air fryer for about 10-15 minutes.
Garlic Roasted Green Beans are a great side dish any time you need a quick vegetable that’s simple to make. You only need a few ingredients and these are super flavorful from all the garlic – plus roasted green beans are so much better than boiled!

If you’ve never tried garlic roasted green beans, I’m pretty sure you’re going to love them. You only need five ingredients and two of them are salt and pepper!
The green beans are roasted with olive oil and garlic which turns golden and caramelized giving the whole dish so much flavor. It also smells pretty amazing while it’s cooking!
This dish is easy to prep in about ten minutes and it’s one of my favorite easy side dishes to make all year long or for the holidays. If you’ve never roasted green beans or added tons of garlic – you MUST try them. I know you’ll love it!

How to make Roasted Green Beans
- Green Beans: be sure to trim the ends, or buy one of those bags of green beans that’s already trimmed. I also love the small haricot vert that you get at the grocery store – they’re smaller and thinner so they cook quicker but my family loves them – especially the kids.
- Garlic – While I love garlic paste, be sure to buy fresh garlic and press it yourself for this recipe.
- Roast vegetables at a hight temperature (400°F) and they’ll be done in 15-20 minutes. Stir halfway though cooking.

How to make Garlic Green Beans step-by-step
- Peel your garlic. I like to use my garlic press to prep the garlic. It’s easier and faster to press garlic than to mince it with a knife. Sprinkle the pressed garlic over the top along with some olive oil, salt and pepper.
- Spread the green beans into an even layer on a baking sheet.
- Roast them for about 20 to 25 minutes or until they’re tender in a 400°F oven.
