These Garlic Parmesan Green Beans are roasted until crisp-tender and browned in spots, then finished with garlic and a blanket of golden Parmesan. They’re the easiest side on the holiday table.
They’re also easy on the shopping list. A bag of fresh green beans, a few cloves of garlic and a handful of cheese make a side dish for six without adding much to the holiday total.
Everything happens on one sheet pan lined with parchment paper, so the oven does the work and cleanup takes a minute.
Serve them next to Pineapple-Honey Glazed Ham and Creamy Mashed Potatoes, or with any weeknight chicken dinner.
Ingredients and Swaps
- Green beans: Fresh beans brown the best. Bags of trimmed beans save time, and they still deserve a rinse. Frozen beans work too (see the recipe notes).
- Parmesan: Grate it from a wedge or use the shaker kind from the pasta aisle. Both turn golden in the oven. Pecorino Romano is a good swap.
- Garlic: Fresh minced garlic has the most flavor. In a pinch, toss the beans with ½ teaspoon of garlic powder at the start instead.
- Olive oil: Any cooking oil you have will work.
- Lemon: Optional, but a squeeze at the end brightens the whole pan.
Tips for Crisp-Tender Green Beans
- Let the oven heat all the way to 425°F before the pan goes in. A hot oven browns the beans before they turn soft.
- Keep the beans in a single layer with a little space between them. A crowded pan steams.
- Thin beans cook faster. If yours are slender, check them a couple of minutes early.
- Add the Parmesan with the garlic, not at the start, so the cheese turns golden without scorching.

Garlic Parmesan Green Beans
Ingredients
Method
- Heat the oven to 425°F. Line a sheet pan with parchment paper.
- Rinse the green beans and pat them completely dry. Spread them on the pan and toss with the olive oil, salt and pepper. Arrange in a single layer.
- Roast for 10 minutes.
- Stir in the garlic and sprinkle the Parmesan over the top. Roast for 5–7 minutes more, until the beans are crisp-tender and browned in spots and the cheese is golden.
- Squeeze a little lemon over the top, if you like, and serve.
Notes
- Dry the beans well. Wet beans steam in the oven and won’t brown.
- The garlic goes in partway through so it doesn’t burn.
- Using frozen green beans? Roast them straight from frozen and add about 5 minutes to the first roast.
- Feeding a crowd? Double the recipe and use two pans so the beans aren’t crowded.
Make-Ahead & Storage Tips
- Trim the green beans up to 2 days ahead and keep them in the fridge in a bag lined with a paper towel.
- Refrigerate leftovers for up to 4 days.
- Reheat in a 400°F oven or a hot skillet for a few minutes so they crisp back up.
- Roasted green beans turn soft when frozen, so these are best made fresh.
Garlic Parmesan Green Beans Questions
Can I use frozen green beans?
Yes. Roast them straight from frozen and add about 5 minutes to the first roast. They won’t brown quite as much as fresh, but the flavor is still good.
Can I use canned green beans?
Canned beans are already soft, so they won’t roast up crisp-tender. Save them for casseroles and use fresh or frozen here.
How do I keep the garlic from burning?
Add it for the last 5 to 7 minutes only. Minced garlic burns quickly at high heat, and stirring it in partway through keeps it golden.
