These roasted green beans with garlic and olive oil are so tasty and they are also very easy to make.
Only 15 minutes in a 425°F oven and this delicious side dish is ready! Even the leftovers are good.
I make green beans quite often for my family (the Picky Eater likes them which is a huge incentive). So I try to vary the ways I prepare them to ensure we don't get bored.
I have experimented with many recipes over the years, and I have to say that oven-roasting is one of my favorite ways to prepare green beans. It helps that my family members enjoy this recipe too and that even the leftovers are tasty.

Ingredients
You'll only need a few ingredients to make these roasted green beans. The exact measurements are listed in the recipe card below. Here's an overview of what you'll need:
- Fresh green beans: I don't recommend trying to bake frozen (or frozen and defrosted) green beans. I tried frozen and it wasn't as good. Fresh is definitely the way to go.
- Olive oil: This is by far my favorite oil to cook with - it's so delicious. But if you'd rather use an oil with a higher smoke point, avocado oil is another good (though not as flavorful) option. You could also use melted butter - I often do.
- To season: I use kosher salt, black pepper, and garlic powder.
Variations
- I often use melted butter instead of olive oil. It's delicious!
- Add more spices. Good options that I tried and liked include onion powder, dried thyme, and red pepper flakes.
- Immediately after pulling them out of the oven, sprinkle the green beans with dry-grated parmesan cheese. The cheese is just lovely on the beans and greatly enhances their flavor.
Roasted Green Beans Instructions
Baking green beans in the oven is one of the easiest ways of cooking them. Scroll down to the recipe card for the details. Here are the basic steps:
You start by coating fresh green beans in olive oil, kosher salt, black pepper, and garlic powder.
I use my hands to make sure the beans are well-coated:
Now, bake them in the oven until they are tender and browned in spots, about 15 minutes at 425°F. That's it! How easy is that!
Expert Tips
- As with most vegetable recipes, I urge you to avoid overcooking the beans. You want them to be al dente - just like pasta. When done, they should still have a "bite" and a bit of crunch - you don't want them soft and mushy.
- I actually prefer garlic powder to fresh minced garlic in this recipe, because it's easier to evenly distribute. But if you prefer to use fresh minced garlic, that's fine too.
Recipe FAQs
Both are great! I actually love making boiled green beans, then dressing them with kosher salt and butter. Sometimes the simplest recipes are the best!
But oven baking does have its advantages, and I love the way it makes vegetables crispy and delicious, especially when roasted in tasty olive oil with garlic.
Yes. Like all veggies, you should wash them before cooking. For this recipe, do make sure to dry them thoroughly. You want them to roast in the oven, not steam.
Add fat and salt them generously. Either olive oil or butter - both are delicious. See this recipe for green beans almondine, for example.
The French have always known that the secret to tasty vegetables is to add butter, olive oil, and/or cheese. We should listen to them. They are smart people.
Serving Suggestions
Since I roast them in a 425°F oven, I like to serve these green beans with main dishes that I can cook in the same oven. So I often serve them with one of the following:
- Baked salmon - just like the beans, it only needs about 15 minutes in the oven. So these dishes are perfect to cook together.
- Baked cod - same as the salmon, it's very convenient when the main dish and the side dish can be cooked in the same oven for the same amount of time.
- Keto chicken parmesan - this is a fairly rich main dish, so I like to serve it with a side of vegetables to balance it out.
- Baked chicken legs - these need to spend about 45 minutes in the oven, so simply put them into the oven 30 minutes before the green beans.
- Roasted rack of lamb - this rich and fatty meat is nicely balanced out by the crisp vegetables.
Storing Leftovers
The leftovers keep well in the fridge, in an airtight container, for 3-4 days. I actually like to eat them cold, like you would eat antipasti. You can also gently reheat them in the microwave, covered, at 50% power.
