I had an “Ah-ha!” moment last week that I just had to share with you. I always thought frozen broccoli wouldn’t work well for roasting because it’s just too wet (it is blanched in hot water before freezing), but a couple weeks ago and a friendly commenter mentioned that they roast frozen broccoli all the time and it turns out great (this is why I love to hear your thoughts and experiences). So, I tried it, I loved it, and now I’m sharing it! Oven Roasted Frozen Broccoli is officially my new favorite easy side dish.
See this recipe used in my weekly meal prep.
Why Roast Frozen Broccoli?
Not only is frozen broccoli generally less expensive than fresh broccoli, but it’s already washed and chopped, which takes a lot of prep work out of your meal. And because frozen broccoli is blanched before it’s frozen, it’s already partially cooked, which means it takes less time to roast than fresh broccoli. It’s seriously the easiest side dish ever and it goes with just about anything!
Is Roasted Frozen Broccoli Crispy?
Roasted frozen broccoli florets will not be quite as crispy as roasted fresh broccoli, but the edges of the florets still develop a nice gentle brown color that gives that slightly smoky roasted flavor. The inside of the broccoli florets maintains a nice level of moisture and a good amount of tooth/bite.
How Do You Keep it From Turning Out Wet?
Frozen broccoli can have a lot of ice on the outside, so it’s really important that the broccoli florets are spaced out very well on the baking sheet. If they’re crowded, the ice will not be able to evaporate well and your broccoli will turn out wet and mushy. You can also control the moisture level by roasting a bit longer, which again, allows for more evaporation.
What Do You Use to Season Roasted Broccoli?
I seasoned my broccoli with Montreal Steak Seasoning (coarse ground salt, garlic, pepper, red pepper), but you can customize the seasoning to be whatever your heart desires. I think lemon pepper would be great, as would chili powder, smoked paprika, and cumin. Play with it! :)
Oven Roasted Frozen Broccoli
Servings 2 to 3 servingsIngredients
- 1/2 lb. frozen broccoli florets ($1.00)
- 1 Tbsp olive oil ($0.16)
- 1/2 Tbsp Montreal steak seasoning ($0.07)
Instructions
- Preheat the oven to 400ºF. Line a baking sheet with parchment paper. Spread the frozen florets out over the baking sheet (no need to thaw).
- Drizzle the olive oil over the florets, then sprinkle the Montreal steak seasoning over top. Toss the florets in the oil and seasoning until everything is evenly distributed (it's okay if a lot of it falls onto the baking sheet, it will be stirred and redistributed again later).
- Transfer the baking sheet to the oven and roast for 20 minutes. Take the baking sheet out and use a spatula to stir the broccoli and redistribute the oil and spices. Return the baking sheet to the oven and roast for another 10 minutes, or until the broccoli develops the amount of brownness desired. Serve hot.

How to Roast Frozen Broccoli – Step by Step Photos
Make sure you buy “broccoli florets” and not “broccoli pieces” for this recipe. Broccoli pieces are usually at least half-stem pieces, which can be great for things like broccoli soup, but not as good for recipes like this. Preheat the oven to 400ºF before you begin so that it’s fully up to temp before the broccoli goes in.
This is the steak seasoning I used. Some brands call it “Montreal Steak Seasoning” but it’s basically a really coarse mix of salt, pepper, garlic, and a couple other spices. It’s so delish! You can use this seasoning or any other seasoning blend for your roasted broccoli.
Line a baking sheet with parchment then spread the frozen broccoli florets out over the baking sheet. Drizzle with 2 Tbsp olive oil and 1/2 Tbsp steak seasoning. Toss the broccoli in the oil and spices to distribute them over the surface. It’s okay if a lot of it ends up on the parchment instead of the broccoli because it will be stirred later and the seasoning will stick better then (as opposed to now when it’s frozen).
Roast the broccoli in the fully preheated oven for 20 minutes, then take the baking sheet out and give the broccoli a good stir. The spices should stick to the broccoli a little better now. Return the sheet to the oven and roast for another ten minutes, or until the edges are browned to your liking. Serve immediately.
Enjoy as a side dish with your favorite meal, or just on its own with a little sauce for dipping! (pictured with ranch dressing)
Does this reheat well? Or will it be soggy? Wondering if I could use this for my meal prep!
I think it does well personally! I make a big batch once and eat it all week ;)
I think I may have put a little too much seasoning on mine so a few of the bites I had were a little powerful but overall it tasted great and the broccoli added some great flavors to my meal!
This broccoli is so good., love it!
So easy and so delicious. As The Beth says, it doesn’t go from frozen to *crazy* crispy, but it is so very good. I am going to try it with fresh just to see how much I like it.
But seriously–dump, drizzle, season, stir? Yes, please!B
Thank you for the great dishes you make Brenda Tippens st Petersburg fl
Super easy and hubby and I love it! We have roasted broccoli twice a week thanks to this recipe. I use olive oil, chili powder, dash of black pepper and dash of salt and shake it up in a ziplock bag. Comes out perfect every time!
Wow I was truly surprised. I am not a fan of frozen broccoli but this recipe totally transforms it. I used salt/pepper/garlic powder in place of the Montreal. I only needed to bake ours about 25 minutes total. I am very happy to have a new easy side to add to the rotation, I will definitely keep frozen broccoli in the freezer from now on!
Hmmm, mine was mushy. What did I do wrong?
I would try roasting them a bit longer to help them dry out a bit. Also, you may want to check the accuracy of your oven’s temperature, because if it’s not quite hot enough the ice will just melt and not evaporate quickly, which can leave you with mushy broccoli. That being said, roasted frozen broccoli will always still be softer than roasted fresh broccoli.
Have you ever tried roasting frozen green beans? I may have to experiment and see how that comes out. We love them roasted but fresh can be hard to find.
We haven’t tried that yet! But keep us posted on how it goes.
I roast the Trader Joe’s French Green Beans all the time – really good, fast and easy!
I’ve made this recipe a couple times and thought it was great! Definitely best right out of the oven. I use Penzey’s Ruth Ann Muskego Avenue seasoning instead of Montreal steak. It’s a blend of salt, pepper, onion, garlic, lemon peel and I use it on…pretty much everything at least once.
Also do you think I could use a Silpat (silicon baking mat) instead of parchment paper? I’m trying to reduce my disposables in the kitchen :)
I used garlic powder and a ridiculous amount of salt, and my picky kids devoured it!!
I have been led astray by other roasted frozen broccoli recipes, but this recipe did not disappoint! It definitely has snuck its way many times into my meals for each week! I did not have any Montreal steak seasoning on hand so I used Italian seasoning (rosemary, thyme, oregano, basil, sage). The broccoli is crisp and delicious and holds a lot of flavor. Can’t wait to make it again tonight! Thank you for this great recipe and saving me from choking down bland boiled frozen broccoli!
Hooray! Thanks Cassie!
Accidentally bought frozen chopped broccoli (meant for broccoli cheese soup) instead of florets but it still turned out tasty! I put broccoli “sprinkles” on my toddler’s pasta and he ate it up. Can’t wait to try it again with florets! Thanks for the time and money saving tip!
Ha! I love the sprinkles!
It was amazing. Thanks so much for letting us know that frozen broccoli is actually better than fresh, when roasted. Will definitely be making many times over in the future.
You’re welcome!
This is literally my go to veggie now, so easy and I always have frozen broccoli on hand. I truly appreciate all your awesome recipes, I use your website at least a few times a week!
