    Roasting frozen vegetables is a super simple way to get veggies in your diet without the hassle of peeling and chopping. In one minute you can have a nutritious side dish in your oven roasting for dinner.

    Why frozen vegetables?

    Everyone knows that fresh vegetables are good for you. We are constantly being told to eat more produce. Often when we embark on a healthy eating journey, we get ambitious and buy ALL the fresh veggies from the grocery store and then end up shamefully tossing them in a a couple of weeks after they go bad. I get it. After a long busy day it can be a lot of work to peel and chop that big butternut squash or messy beets.

    Enter frozen veggies. The prep work is already done for you. No peeling and chopping required. Just open the bag, dump it on a baking sheet, drizzle with olive oil, and season before popping it in the oven.

    They reduce food waste when you keep a combination of fresh and frozen vegetables on hand. Frozen vegetables are also great to keep stocked up for emergencies. I always keep a hefty stock of them in my freezer.

    The best way to prepare frozen vegetables

    Roasting is by far, in my opinion, superior to any other cooking method for frozen vegetables. Roasting helps achieve crispy vegetables similar to using fresh. Of course, they will be slightly mushier in texture than fresh, but not by much.

    The convenience factor wins out over the slight difference in quality. We are big fans of roasting frozen veg in my house. Mama needs easy!

    • sweet potatoes

     

    Tips for roasting

    Watch the video below for a detailed hands on explanation for how to roast vegetables.

    Use high heat

    To roast your vegetables and get a crispy texture, you will need a very hot oven. I find that a big mistake when a lot of people making when cooking is they cook everything at 350 degrees. To get your veggies nice and browned and delicious you need a much higher temperature. Roast at the minimum 425 degrees F. If your vegetables seem to not be getting browned to your liking, increase the temp to 450 degrees F.

    Use parchment paper

    Lining your baking sheet with parchment paper is perfect for easy clean up. It also helps prevent the vegetables from sticking to the pan. I prefer to use unbleached parchment paper.

    Do you need to thaw frozen vegetables before roasting?

    No, you do not need to thaw the vegetables before roasting. Simply place them frozen on the tray and break up any pieces that are stuck together. Remove any large ice chunks as well to prevent steaming.

    Oil and season

    Drizzle your vegetables with olive oil or your favorite cooking fat, spread vegetables into a single layer with plenty of room, and salt and season generously. You can play around with the flavors: rosemary, thyme, oregano, garlic, ranch seasoning.

    How long to roast?

    Here is where you have to use your intuition and senses. For vegetables like broccoli and cauliflower, it will likely take around 20 minutes. For root vegetables like beets, they will take 30-45 minutes. Start checking around 20 minutes to see if they are roasted and browned to your liking. If they are done but not as crisp as you like them, you may consider cranking up the heat or turning on broil for a minute or two. It also depends on how large the chunks are. Larger chunks take longer to cook. Use your senses to guide you.
