Turn a simple bag of frozen green beans into a delicious, vibrant side dish with this frozen roasted green beans recipe! Frozen green beans are tossed in a tasty seasoning mix, roasted to perfection in the oven, then finished off with a sprinkle of parmesan. You get perfectly crisp, cheesy, and garlicky green beans – the perfect addition to your veggie side dish rotation!
I love frozen veggies as much as I love fresh ones. They’re incredibly convenient to have on hand and always ready to go for a last-minute meal. Plus, they last much longer than fresh produce, so you can always rely on them for quick options when your fridge is running low. While there are plenty of ways to cook them, roasting is my favorite – it brings out their natural sweetness and they become beautifully crispy on the outside yet deliciously tender on the inside.
Take these frozen roasted green beans, for example. I just toss them in a simple seasoning mix, then roast them in the oven. They come out super flavorful every time, with crisp edges and a tender bite. It’s the easiest, most delicious way to enjoy green beans without having to buy them fresh, and no one will know they were cooked from frozen.
You can enjoy frozen roasted green beans all year long but are best in the winter when fresh green beans are out of season. They make a nice addition to your holiday spread; perfect for brunch, lunch, or dinner and for sharing with a party crowd!

Ingredients You Need
- Frozen cut green beans: I use frozen cut green beans, but you can also use whole if that’s what’s available. I don’t recommend using frozen French green beans because they tend to dry out very quickly in the oven.
- Extra virgin olive oil: Helps the green beans roast to crispy perfection.
- Garlic powder: Adds a delicious savory flavor that enhances the sweetness of the green beans.
- Onion powder: Complements the garlic powder with its subtly sweet and savory flavor.
- Salt: Helps bring out all of the flavors. I usesea salt.
- Ground black pepper: Freshly-ground black pepper makes a huge difference!
- Parmesan cheese: I recommend using freshly-grated parmigiano-reggiano for the best flavor, but store-bought will also work.
Step-By-Step Instructions
Don’t you just love fast and easy recipes like this? Frozen roasted green beans have saved me countless times on busy weeknights or when I needed a quick side dish for meals. This recipe comes together in 2 simple steps – follow them closely and they’re guaranteed to come out perfect!
Step 1: Toss
Preheat your oven to 400 F.
Toss the frozen green beans with olive oil in a medium mixing bowl, then season with garlic, onion, salt, and pepper. Toss again to thoroughly coat the beans.
Step 2: Bake
Next, arrange the green beans in an even layer on a baking sheet and roast for 15 minutes.
Remove from the oven and stir them around on the sheet.
Sprinkle the cheese evenly over the top of all the green beans. Return to the oven and continue baking for another 10 minutes. The reason why we’re adding the parmesan cheese towards the end is so that it gets nice and golden without burning, as it will burn if cooked at a high temperature the entire time.
Finally, check your green beans – they are done when they’re soft and tender. Remove from the oven, cool for a few minutes, then serve.
Substitutions
The good news is, that you probably have most of the ingredients for frozen roasted green beans on hand. But if you’re missing something or want to switch it up, I’ve got some great alternatives for you!
- Extra virgin olive oil: If you don’t have extra virgin olive oil, you can substitute with sesame oil, avocado oil, or any vegetable oil of your choice. Melted unsalted butter will also work great.
- Garlic and onion powder: When it comes to vegetables, I always recommend seasoning to your preferences, so feel free to use your favorite spices or seasonings. Italian seasoning and smoked paprika are good options.
- Parmesan cheese: To make this recipe dairy-free, use nutritional yeast in place of cheese. I recommend using half of what the recipe calls for parmesan.
Variations
Frozen roasted green beans are amazing as is, but it’s nice to switch it up from time to time to keep the excitement going. Try these equally tasty variations:
- Want your green beans extra crispy? Add 1 cup of panko breadcrumbs to the seasoning mix. Toss the beans until they’re coated in the crispy crumbs!
- If you’re up for a delightful crunch, top the green beans with 1/4 cup slivered almonds or chopped pine nuts during the last 10 minutes of roasting.
- For a heartier side, toss the green beans along with 4 oz of chopped uncooked bacon, then proceed with the recipe as is.
- Add a pinch of crushed red pepper flakes or a dash of cayenne pepper to the seasoning mix for some heat.
- Toss the green beans in soy sauce and sesame oil before seasoning and garnish with toasted sesame seeds for a unique Asian-inspired twist. Omit the cheese.
Expert Tips
- Keep the green beans cold: Don’t take the green beans out of the freezer until your oven is preheated. You don’t want them to thaw while you’re getting everything ready, or the baking time will be off.
- Don’t thaw: Following that thought, thawing frozen green beans before roasting seems like it would make sense, but it’s best to cook them frozen. Roasting thawed beans will result in mushy beans!
- Use a roasting rack: Use a roasting rack if you have one. Keeping them up off the pan helps them cook evenly and crisp up better.
- Roast to preference: Roast the green beans to your desired doneness. This recipe makes tender-crisp green beans, but you can roast them a little longer until they are softened.
- Avoid using foil: Lining the pan with foil is for keeping the food moist, that’s why it’s ideal for roasting meat. When it comes to frozen veggies, we want them to get nice and crisp, so skip the foil to allow for better airflow and a crispier texture.
How to Store This Recipe
Frozen roasted green beans taste best fresh out of the oven. If you have leftovers, place them in an airtight container and store them in the refrigerator for up to 5 days. Reheat in the broiler or air fryer until warmed through.
This dish can also be frozen, although the texture won’t be as good when reheated. I recommend using them for soups, sauces, or casseroles.
To freeze cooked frozen roasted green beans, cool them completely, transfer them to a small sheet tray, and store in the freezer. Once frozen, place the beans in a freezer-safe container and keep in the freezer for up to 1 month. Thaw completely in the refrigerator before reheating.
What to Serve with Frozen Roasted Green Beans
Frozen roasted green beans make a wonderful side dish for so many dishes. I love to pair them with a starch and a protein for a well-rounded meal. Garlic mashed potatoes, roasted sweet potatoes, rice, quinoa, or farro are great choices for a starch pairing.
This versatile side goes with any type of protein, may it be chicken, pork, beef, fish, or seafood. My favorite mains to serve green beans with are parmesan-crusted chicken, crispy fried pork chops, bacon-wrapped filet mignon, chili-baked salmon, and seared scallops.
