While we love summer fresh garden green beans, Roasted Frozen Green Beans are a great alternative in the winter, and perfect when you need a quick side dish in a pinch! Prepped in just a minute and hot out of the oven in 20 minutes, this handy recipe is simply delicious!
- A Fall Back Side Dish! - Need a quick dish to use up that bag of green beans in the back of the freezer? This is it! Frozen green beans are great to keep on hand! They can be thrown straight into soups, Chicken Veggie Pot Pie or Tater Tot Casserole. You can blanch them in boiling salted water for a few minutes and serve with butter, or roast them in the oven!
- From Fresh to Frozen - Fresh green beans picked from the garden are obviously the best! In the winter, the grocery store green beans can be pretty terrible and you're better off buying frozen. Frozen green beans are picked in season and then blanched, cooled, and frozen to preserve their freshness and green color. When you're roasting frozen green beans, they are already pre-cooked. Just 20 minutes in the oven to give them a little caramelization is all it takes!

- Frozen Green Beans - It's great to have a few bags of frozen vegetables on hand for a quick side dish when you need it! Frozen vegetables are budget friendly, so go for organic if you can for the best quality. This recipe uses a 16 ounce bag, but this recipe can be adjusted up or down for any amount.
- Olive Oil, Salt and Pepper - The basics of roasting are the same for frozen green beans! Just a drizzle of olive oil, salt and pepper is all that's needed to bring out their natural flavor.

Recipe Notes and Helpful Tips
- Preheat the Oven - Frozen green beans need to go from frozen to cooked, hot and fast! This will keep them from getting watery or mushy. You want to keep your green beans frozen until you're ready. Preheat your oven to a hot 425°F, and use convection bake if your oven has it, which means the fan is blowing the heat around. Adding them to the oven before it is preheated can cause them to slowly thaw and steam in their own liquid instead of roast.
- Use a Large Baking Sheet - To roast properly, the green beans need room to spread out so they don't steam instead of roast.
- Serve Right Away - Roasted frozen green beans are super quick to prepare, and are not the recipe to make ahead, or have resting too long. They are best hot out of the oven!
- Freeze your Own Garden Fresh Green Beans! - In the peak of summer when the garden is full, we like to Blanch and Freeze Garden Green Beans to use all winter long! Those frozen green beans are perfect to use for roasting!
- Storage - Leftovers can be stored in the fridge and should be eaten the next day, they will be a bit softer and not quite as good as fresh from the oven!
Recipe FAQs
No, frozen green beans should go from frozen into the hot preheated oven to avoid getting watery or mushy. No need to thaw or rinse.
I like to top roasted frozen green beans with a few pats of butter to melt and shredded Parmesan cheese. You could also add fresh minced garlic in the last 5 minutes of roasting. Fresh herbs or a squeeze of fresh lemon juice make great toppings. You can also add dried spices before roasting such as garlic powder, onion powder, dried thyme or oregano.
Yes, no matter the size of your bag of frozen green beans, or if you want to use two bags or just half a bag, the recipe is pretty much the same. Adjust the oil, salt and pepper and roast. If using two bags of frozen green beans, spread them out on two large sheet pans so they have plenty of room to roast.
Yes, frozen green beans are picked in season, washed, trimmed and blanched quickly in boiling water. They are then cooled immediately and frozen. This process helps them retain nutrition and their vibrant green color. When you are using frozen green beans, know that they are already partially pre-cooked and don't need much additional cooking time.
