Save Recipe

I’m a HUGE fan of green beans, and luckily my three kiddos are too. I’ve loved experimenting and learning how to cook fresh green beans over the years.

Roasting them is my absolute favorite and I love to experiment with flavors, like the garlic and Parmesan in today’s recipe! (If you like roasting veggies you should also check out my Oven Roasted Peppers and Roasted Russet Potatoes!)

How to Prep and Trim Green Beans

I grew up with farmer grandparents so I go old school and snap the ends of my green beans off by hand. For those who want to do it otherwise, it’s quite easy.

  • Wash in cold water and pat dry.
  • Cut the ends with kitchen shears as you wash them or line them up on a cutting board with the ends even and slice them off with a knife.

Have extra beans? You can use them in this From Scratch Green Bean Casserole or my Pesto Potato Salad!

How long should I roast my green beans?

Roasting is very forgiving and you can adjust the cook time according to how you crisp you like your green beans.
Roasting at 400 degrees for 20 minutes leaves the beans tender yet still crispy. My children prefer them a little softer so I have roasted them up to 30 minutes in the past to get that texture right.

Can I use frozen or canned green beans?

You cannot use canned green beans because they are pre-cooked the end result of roasting will be mushy. To use frozen green beans, thaw and thoroughly dry before roasting.
For the very best results, however, find nice fresh green beans when making this recipe.

How do you store leftovers?

Keep these beans in an airtight container in the refrigerator up to 3 days. Reheat in the microwave, or for a more crisp result warm in the oven at 350 degrees until heated through.

Are green beans the same things as string beans?

Yes! String beans, green beans, wax beans, pole beans are all referring to the same veggie. There are different varieties such as Romano and haricots vert but they are interchangeable in this recipe. See this article for a deep-dive into all the different types of green beans.

I hope you love this recipe as much as we do, it’s a tasty and family-friendly way to get fresh veggies in your meal plan.
