Quick & Easy Green Bean Recipe

Roasted vegetables are easily one of our favorite healthy sides to make when we are short on time and creativity. Sometimes we just don’t have the time or energy to whip up Mashed Potatoes or Cheesy Scalloped Potatoes. So, today we have one of our favorite (and one of the easiest!) side dish recipes for you – Roasted Green Beans.

There aren’t any fancy tricks or tips to this recipe. It’s basic, fast, and really delicious. Oftentimes all you need is a fresh vegetable, garlic, and some salt and pepper to put together a tasty side dish.

There is another perk to this recipe, too! You can easily add some other ingredients to dress them up. We like to add red chili flakes when the kids are around or even a drizzle of our Bang Bang Sauce. So when you feel like it, have fun with this recipe, or just keep it simple.

What You’ll Need

This list is short and sweet! Just add some fresh green beans to your shopping list and you’re good to go.

  • Green Beans: Buy trimmed green beans to make things even easier because the work is already done for you.
  • Olive Oil: Or use the cooking oil of your choice.
  • Garlic: You could also use a few sprinkles of granulated garlic or garlic powder instead if you do not have fresh garlic. Just remember to use less when using dried spices because they are dense in flavor.
  • Salt and Pepper

  • Use different beans or another green vegetable. This recipe also works with wax beans (yellow beans) or other green veggies like broccoli.

  • Use different spices. Try out some different spices like paprika or cumin for bursts of flavor.

How to Make Roasted Green Beans

The steps are very straightforward and your green beans will be ready in no time at all.

First, preheat the oven and prepare a sheet tray. You’ll want to line a sheet tray with parchment paper or foil for easy cleanup.

Then toss everything together. Add the green beans, oil, and seasonings to a large bowl and toss.

Spread the beans out on the sheet tray. And please make sure that they are spread evenly and not in large piles or they will not cook evenly.

Next, bake the green beans. You’ll roast them in the oven for about 20 minutes (or until they are tender). Then serve them immediately after coming out of the oven.

Tips for Success

Below are some helpful tips to follow when making this recipe.

  • Buy green beans that have been trimmed already. This eliminates the step of having to trim them yourself and can save you some time.
  • Make sure that the green beans are dry. If you try to roast vegetables that are still wet (from cleaning or rinsing) they will not get crispy when roasted.
  • The garlic needs to be minced fine. If you have large chunks of garlic it will not spread out evenly when tossed with the green beans and the flavor won’t be as good!

What to Serve With Oven Roasted Green Beans

Here are some of our favorite ways to serve this delicious green bean recipe.

  • Steaks: Green beans pair perfectly with a good steak! And our Air Fryer London Broil is a great recipe to try.
  • Chicken Dishes: Keep it simple with our Crockpot Chicken and Stuffing recipe. The chicken cooks all day and you only need to prep the green beans before eating!
  • Seafood: These beans pair great with grilled fish or Garlic Butter Shrimp. You can add a side of rice or pasta and you have a balanced meal!

How to Store & Reheat Leftovers

Then you can reheat them in a saute pan on the stovetop, in the oven, or the air fryer.

Can I Freeze These?

Yes, you can freeze these Roasted Green Beans but keep in mind they won’t be as tender and crispy after freezing. It’s best to reheat them in the oven at 400°F or in an air fryer.
