If you are looking for a simple and delicious vegetable side dish to go with any meal, roasted green beans tossed lightly in garlic and olive oil and then sprinkled with Parmesan cheese is the perfect choice. In my family, we try to have a vegetable with every meal. Since these are easy and quick to make, they tend to be my go-to—and the kids absolutely love them!

If you aren’t a fan of vegetables, roasting them is one of the best and easiest ways to add delicious flavor to what are typically bland vegetables. Green beans are so easy to roast, and high temperatures bring out their incredible flavor without making them mushy. They stay crisp and tender, and they develop an amazing char that adds depth of flavor that cannot be compared to canned or frozen products.

Green vs. String Beans: What's the Difference?

String beans and green beans are basically the same. Many years ago, when people were crossbreeding green beans, a variety developed and became well known for having a fibrous, inedible string that ran down the seam of the pod. Today, most of the green beans sold in stores and at markets don’t have this string anymore, so it can be made with any type of green bean available to you.

How to Trim Fresh Green Beans

When you are trimming green beans, you will notice that one side is soft, and the other side has a hard, rough stem. Line your beans up on a cutting board with all the stems aligned on the same side. Use a sharp knife and slice the stem off by cutting it all the way through.

Cook's Tips

  • If you want to add more flavor to this dish, add a few lemon slices, chopped parsley, or fresh herbs like basil or dill.
  • If you don’t have any fresh garlic, a pinch of garlic powder will add the flavor you’re looking for.
  • Make sure that your green beans are completely dry before you roast them. Make sure to coat them well with oil and make sure they are straightened out in a single layer, so they cook evenly.

Health Benefits of Green Beans

Green beans are something a lot of households are familiar with. They go by several names, but almost everyone knows them by sight. Something that isn’t commonly known though is they have a lot of health benefits.

They are low in calories but they contain a lot of important nutrients that can be beneficial in different areas of your life. One benefit people notice is that since they are high in soluble fiber, they can reduce your LDL cholesterol, which is the bad cholesterol that your body needs to fight against.

They Protect Gut Health

The fiber in green beans can help your digestive system run healthily and smoothly. If you have certain digestive orders though, this fiber can do more harm than good. If you are on a diet that recommends you avoid high FODMAP foods, you still may be able to enjoy this vegetable because they are a low FODMAP food.

They are also a great source of vitamin K, calcium, and plant-based iron, making it great for people who have iron deficiency anemia.
