Can I put Frozen Broccoli in the oven without defrosting it ?

Yes! The key here is to not let the frozen broccoli thaw at all before you place it in the oven. This is the secret to making sure that the broccoli is not mushy when you eat it!

Tips for Success

  • Do not let your broccoli thaw: the broccoli should go straight from freezer to a preheated oven. Do not let your broccoli thaw before cooking, as this can result in it becoming mushy.
  • Use parchment paper for easy cleanup: using parchment paper is one of my favorite time saving hacks that really cuts down on scrubbing pans.
  • Add parmesan cheese: try topping your finished broccoli with parmesan cheese for an extra boost of flavor

My favorite way to eat this roasted frozen broccoli is with my Easy Crock Pot Baked Ziti (pictured below).

This would also be yummy served up with some greek yogurt mac and cheese for a kid friendly dinner ready quick!

Worked like a charm! Thank you for this recipe! I usually roast fresh veggies because frozen always came out soggy but this changed everything!

  1. Would it be better to thaw the broccoli, blot it dry, and then roast – to avoid the water problem that was mentioned? Thank you.

  2. My teenage son loved this so much, he told me to always cook broccoli for him this way.
    I’m also going to try it with frozen green beans.

  3. I don’t have parchment paper. Can I spray aluminum foil with oil spray? Will that keep the vegetables from sticking?

  4. Do you preheat the oven for this recipe? Or put the broccoli in a cold oven and then turn on the heat? Thanks,
