This easy 5 ingredient oven roasted green beans recipe delivers crispy edges and tender centers with hardly any effort. Let your oven do the work and enjoy a simple side that makes any meal better.

The Easiest Green Beans You’ll Make
- Flavor: Savory with a hint of garlic, perfectly roasted to bring out toasty flavors and a subtle peppery kick.
- Why Make It: This beginner friendly, hands-off side cooks while you finish the main, with very little cleanup thanks to parchment.
- Tools needed: All you need is a rimmed baking sheet, parchment paper, and a mixing bowl. Or save dishes and simply toss everything directly on the sheet.
- Serving Suggestions: I love serving these as my default veggie! While the main is sizzling on the stove, I pop these in the oven and know they’ll be perfectly roasted and ready. They pair perfectly with chicken and pork.

Simple Ingredients, Big Flavor
- Green Beans: When prepping, I look for bright, firm beans that snap.
- Olive Oil: Use just enough to coat the beans so the seasonings stick and the beans roast evenly. Too much oil can make them limp instead of crisp-tender.
- Salt and Pepper: Season with a light amount of kosher salt, then adjust to taste after roasting. Add black pepper before or after cooking for depth or bite.
- Garlic: You can use finely crushed garlic, but be careful as it can burn easily. Garlic powder is easier to control flavor without fear of burning.
- Variations: Finish with a touch of lemon, a sprinkle of Parmesan, or a drizzle of balsamic glaze for extra flavor. Add crunch with toasted almonds or a kick with red pepper flakes or Cajun seasoning.


How to Roast Green Beans in the Oven
- Clean and prep green beans.
- Toss the beans in oil and seasonings, then roast (full recipe below).
Pro Tips for Perfectly Roasted Beans
- Be sure to dry beans thoroughly, or you can wash and trim beans early in the day then let them air dry. Dry beans will brown beautifully in the oven.
- Coat bean with just enough oil so the seasonings stick and beans roast evenly. Too much can make them limp.
- For crispier beans, space them out so they crisp on all sides. You can also broil for 30 to 60 seconds at the end of cooking.
- If the beans taste flat, you can finish with a pop of lemon juice or a tiny balsamic drizzle.

Storing and Reheating Leftovers
Refrigerate leftovers in an airtight container for up to 4 days and in the freezer for up to 3 months. Reheat in the oven or toaster oven at 400°F for 5 to 8 minutes, or in an air fryer at 350°F to 375°F for 3 to 5 minutes to regain some crispness. Leftovers can also be used in soups, casseroles, fried rice, or meal prep bowls.
