Ingredients List
All it takes is 4 basic ingredients to have these garlic green beans on your table. Here’s what we need from the grocery store:
- green beans – there are two main types of green beans that are easily available, regular green beans or Haricot verts (French green beans). The long, slender ones cook faster and kids absolutely love them!
- olive oil – I love fruity olive oil, but avocado oil will also work.
- garlic – fresh garlic cloves add so much flavor. Use 4 medium – large garlic cloves minced to a fine texture. You can also sprinkle on some garlic powder if you are a garlic lover.
- salt – fine sea salt enhances all those garlicky flavors.

How to Roast Green Beans
Baked garlic green beans are so easy to make, you’ll wonder why you never started roasting your string beans in the first place. Here are the step-by-step instructions:
prepare green beans
Preheat the oven to 400ºF.
Add green beans to a large baking sheet.
Drizzle on olive oil and minced garlic. Use your hands to toss and arrange in one single layer; allowing some overlap is okay.
roast
Bake string beans for 15-18 minutes, until lightly golden. No need to stir green beans while roasting.
serve
Serve green beans warm with your favorite meal (check out some of our favorites below!). Finish with some lemon juice or parmesan cheese, if desired.
Recipe Tips
Here are some tips for making the best garlic roasted green beans:
- prepare in advance: trim the ends of the green beans with a sharp knife on a cutting board. Or buy one of those bags with the ends already trimmed. Keep the one pound of green beans in an airtight container or the same plastic bag in the fridge until ready to roast in the oven.
- no need to boil: there is no blanching or par-boiling the green beans. Simply season and toss in the oven.
- dry the green beans well: spread the green beans out on paper towels or a clean kitchen towel to thoroughly dry. Excess moisture will prevent the green beans from getting crisp and caramelized.
- do not open the oven: not touching the string beans during the entire cooking time ensures they cook through and get those charred, blistered spots that add so much flavor.
- try the air fryer: you can also cook these in an air fryer. Air fry at 400ºF for about 10-15 minutes. You will probably have to air fry in 2-3 batches.
Serving Suggestions
Talk about a Thanksgiving side dish that will not stress you out. Baked green beans with garlic are a simple healthy side dish best served with any of the following:
- Weeknight Dinner: Serve these as the vegetable side dish to any main dish, including Sweet Spicy Glazed Salmon.
- Meal Prep: Prepare these at the beginning of the week and package for meal prep with your favorite protein, complex carb, and fat.
- Vegetable Side Dishes: Enjoy with a holiday table full of vegetable side dishes, including Loaded Cauliflower Casserole, Bacon Apple Brussels Sprouts, and Cauliflower Mashed Potatoes.
- Salads: Add even more greens with Shaved Brussels Sprouts Salad and Fall Kale Salad.
Flavor Variations
You can’t go wrong with simple garlic green beans. But if you’re looking for some different flavors to add, here are a few suggestions:
- Parmesan and herbs: add freshly grated parmesan and some fresh herbs for maximum flavor, such as thyme, rosemary or parsley.
- Balsamic glaze: finish off the green beans with a balsamic glaze, which you can find pre-made at most grocery stores.
- Sesame and soy sauce: roast the green beans in sesame oil and soy sauce then sprinkle on some sesame seeds for Asian-inspired flavors.
How to Store & Reheat
Make Ahead: Prepare the green beans as instructed. Store in an oven-proof dish tightly covered with plastic wrap in the fridge for 1 day. Follow the reheating instructions.
Leftover roasted string beans with garlic can be stored in an airtight container in the fridge, best enjoyed within 3-4 days.
Reheat in a low oven (300 degrees F) for 5-10 minutes, until warm. Or, pop a bunch in the microwave until warmed through.
Recipe FAQs
Why are my roasted green beans tough?
If you find your green beans are tough after roasting, it was either the green beans were too mature or you didn’t cook them long enough. You could try roasting them for another 3-5 minutes to help soften their texture.
What is the best flavor to add to green beans?
Garlic, of course! But you can also use simple salt and pepper. A little lemon juice and parmesan are also delicious additions.
Should I blanch green beans before roasting?
Blanching green beans means they are already cooked through before roasting. While you can blanch the string beans, I didn’t find this step necessary.
How can I tell when green beans are done?
They should be tender but have a bit of browning on the edges.
