Roasted frozen green beans are crispy and caramelized with a delicious flavor. They are quick and easy to prepare and require minimal effort. Add roasted green beans as a side dish to any meal.
The best way to prepare fresh or frozen vegetables is by roasting them. Roasting brings out their sweetness, caramelizing the natural sugar within vegetables, giving them a delicious savory flavor. Not only does roasting improve vegetables' taste, but the vegetables become beautifully crispy on the outside and deliciously tender on the inside.
These roasted frozen green beans could not be easier to throw together. Like air frying frozen green beans, no washing or chopping is needed. Frozen green beans freeze at their peak of freshness, have a longer shelf-life and are overall more economical.
This delicious vegetable side dish is perfect for busy weeknights. It requires minimal prep time, and there is minimal equipment needed. This quick and easy recipe is sure to be one you add to your vegetable side dish rotation. If you like this recipe, be sure to try my garlic parmesan green beans too.

Can I roast green beans and then freeze them? While roasted vegetables are best eaten after roasting them, you can freeze roasted vegetables. Place cooled green beans onto a small sheet tray and place the tray in the freezer. Once the beans have frozen, transfer them to an airtight container or freezer bag. Freeze the beans for up to 2 months—thaw them completely in the refrigerator before reheating and eating.
