“My teenage son loved this so much, he told me to always cook broccoli for him this way.”
Ingredients needed
- Frozen broccoli florets: do not buy broccoli cuts as half of the bag will be stems. You want to buy broccoli florets specifically.
- Olive oil spray: or other neutral cooking spray.
- Salt and pepper
- Garlic powder
- Onion powder

How to Roast Frozen Broccoli
- Preheat the oven to 420 degrees.
- Line a baking sheet with parchment paper.
- Take the frozen broccoli florets straight from the freezer and place them on the baking sheet in a single layer.
- Spray the florets with olive oil cooking spray, then sprinkle on salt, pepper, garlic powder, and onion powder.
- Roast the frozen broccoli at 420 degrees for 15-20 minutes, stirring once or twice, until desired crispiness.
- Top with optional parmesan cheese and serve immediately.

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!

Awesome recipe, everyone loved it
How would you recommend storing leftovers or for weekly meal prep?
I wouldn’t recommend this for meal prep, it’s not going to be as good reheated.
Would it be better to thaw the broccoli, blot it dry, and then roast – to avoid the water problem that was mentioned? Thank you.
I would not go this route
@Leslie, yeah I was wondering about that. Thanks for the tip!
Going to try this tonight along with baking my spicy chicken thighs.
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.
I don’t have parchment paper. Can I spray aluminum foil with oil spray? Will that keep the vegetables from sticking?
Do you preheat the oven for this recipe? Or put the broccoli in a cold oven and then turn on the heat? Thanks,
The oven needs to be preheated first.
Do I have use olive oil spray or can use another spray?
any cooking spray is fine
