    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 you roast frozen green beans?

    You sure can! Roasting green beans is the best way to cook them, fresh or frozen. After roasting, the beans come out crispy and caramelized with tender centers. The roasting process brings out their sugars and intensifies their flavor. Roasting green beans is a simple way to add vegetables to your plate any night of the week.

    Ingredients

    The ingredients you need for this recipe.
    • Frozen French Green Beans - I buy mine from Trader Joe's.
    • Olive Oil
    • Salt
    • Black Pepper

    See the recipe card for the ingredient quantities.

    How to Roast Frozen Green Beans

    STEP 1 - Preheat the oven to 425 degrees F. Line a sheet tray with parchment paper.

    A large bowl of frozen green beans with a wooden spoon.
    Toss the green beans in olive oil and spices.
    A parchment-lined tray of oiled and seasoned frozen green beans.
    Place the seasoned beans on a parchment-lined tray.

    STEP 2 - In a large mixing bowl, toss the frozen green beans in olive oil and spices until all of the beans are coated.

    STEP 3 - Transfer the seasoned beans to the prepared sheet pan, evenly spreading them out. Roast the green beans for 15 minutes. Stir the beans and rotate the pan in the oven. Cook for 15 - 20 minutes more, or until desired crispiness is achieved.

    Variations

    • With Almonds - Toss ¼ cup of slivered almonds with roasting green beans in their last 10 minutes of cooking.
    • Garlic Roasted - Mix 3 minced garlic cloves with olive oil and seasoning.
    • With Parmesan Cheese - Toss green beans in ⅓ cup of grated parmesan cheese alongside the olive oil and seasoning, then roast.
    • With Bacon - Toss green beans with 4oz of chopped uncooked bacon. Roast as the recipe specifies.

    What to Serve with Roasted Green Beans

    Roasted green beans pair with any cooked protein, pasta, or sandwich. They are a healthy alternative to french fries or chips. This simple side dish makes adding greens to almost any meal easy. Here are a few recipes that I love to serve these tender, crispy beans with:

    • Slow-Cooker BBQ Chicken Thighs
    • Bucatini Pomodoro
    • Buffalo Chicken Quesadillas
    • Sheet-Pan Sausage and Peppers
    • Cracker-Crusted Chicken Nuggets
    • Crockpot Frozen Turkey Meatball Subs
    A parchment-lined tray of roasted green beans with a spatula.

    Suggested Equipment

    • Half Sheet Pan
    • Large Tongs
    • Fish Spatula

    Storage

    Store cooled leftover roasted green beans in an airtight container in the refrigerator for up to 4 days.

    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.

    Expert Tips

    1. Keep the green beans frozen, but de-ice if necessary.
    2. Preheat the oven. Only roast the beans in a preheated oven for even cooking, 
    3. Roast vegetables on high heat. The higher temperature promotes caramelization and crispiness. 
    4. Make sure all green beans are evenly coated in olive oil and seasoning. 
    5. Avoid overcrowding the sheet pan. Space the green beans out on the tray for even cooking.

    Frequently Asked Questions

    Do you thaw frozen green beans before roasting them?

    There is no need to thaw frozen green beans before roasting them. In fact, thawing the beans before roasting them can promote too much moisture resulting in soggy green beans.

    Do green beans need to be blanched before roasting?

    Frozen green beans do not need to be blanched before roasting them.

    What spices go well with green beans?

    Green beans are a blank canvas for flavor. Most savory spices complement this vegetable; however, my favorite spices to season green beans include garlic powder, onion powder, dried parsley, thyme, and crushed red pepper flakes.

    Why are my frozen green beans soggy?

    There was most likely ice from the packaging that melted into your green beans, making them soggy. While you should not thaw frozen green beans before roasting them, do de-ice them to prevent excess moisture.
