I’d love to be one of those people who finds chopping vegetables therapeutic, who derives joy from lovingly slicing broccoli into cute, evenly-sized florets. I do not, which is exactly why I am thrilled to report that you can make ROASTED FROZEN BROCCOLI.

That’s right. Without even thawing the broccoli first, you can make it crispy and caramelized. I bet if you didn’t know the broccoli was previously frozen, you’d never even suspect.

As much as I adore roasted vegetables and as ardently as I believe they are the tastiest way to add more veggies to your diet—I cook a pan almost every single night (usually this Roasted Broccoli and Carrots), and we eat the leftovers for lunches and dinners too—I certainly have my nights when it’s getting late, we’re hungry, and I simply do not feel like taking the time to chop vegetables for roasting.

Or, I’m feeling lazy and I fantasize about having someone else chop my vegetables for me.

Anyone want to be my sous chef? We’ll play peppy kitchen music, then eat oodles of Smashed Brussels Sprouts, Roasted Butternut Squash, Roasted Brussels Sprouts, Roasted Zucchini, and Roasted Potatoes and Carrots. (How’s that for a sell?)

Of course you can buy pre-chopped vegetables, which I do think is a better option compared to eating no vegetables at all. They can be pricey, however, so I started to wonder if there is an affordable way to a) keep eating roasted vegetables en masse but b) avoid chopping them myself without c) having to hire a sous chef.

The answer: roasted frozen broccoli.

I am so pleased to share that YES frozen vegetables can be roasted.

After experimenting with a few different cook times, oven temperatures, and techniques, I found a method for roasting frozen broccoli that yields crispy, delicious results that taste very similar to fresh. No soggy broccoli here!

Key Tips to Making Frozen Vegetables Crispy

With a few easy tips, you can turn a bag of frozen broccoli into hot, crispy vegetables that you’ll want to polish right off of the pan.

  • Roast at a high temperature. I found 450 degrees F optimal.
  • Preheat the oven with the sheet pan in it. When you add the frozen vegetables to an already hot sheet pan, it helps them crisp more effectively.
  • Add some acid. A squeeze of lemon juice livens up the broccoli’s flavor and makes it taste fresh, not flat.
  • A pinch of sugar. Sugar helps the broccoli caramelize in the oven. You can omit it if you like, but I think it’s was worth adding a small amount.

Frozen Broccoli: As Healthy as Fresh

Thankfully, frozen broccoli is just as good for you as fresh broccoli.

  • Frozen broccoli is typically picked and frozen at peak freshness, so it will maintain its nutritional value.
  • Occasionally, frozen broccoli can be more nutritious than fresh broccoli because the blanching process it goes through prior to being frozen can kill bacteria, preserve nutritional value, and prevent spoiling.
  • Frozen broccoli even contains the same amount of folic acid as fresh broccoli.

How to Make Roasted Frozen Broccoli

The Ingredients

  • Frozen Broccoli Florets. Purchase a bag of florets of any size or cook more than one bag at once. The broccoli cooks down quite a bit—I can almost eat an entire 10 ounce bag by myself at one meal—so if you are feeding four or more, I’d suggest doubling the recipe and roasting the broccoli on two pans at the same time.
  • Extra Virgin Olive Oil. Be generous to ensure the broccoli doesn’t burn.
  • Sugar. A little is all you need.
  • Salt and Pepper. Key seasonings for any roasted vegetable recipe.
  • Red Pepper Flakes. Optional if you’d like a bit of heat.
  • Lemon Juice. ESSENTIAL. The pop of acid really livens up the broccoli and is key to making a frozen vegetable taste fantastic.
  • Parmesan. Not necessary per se, but let’s be honest: Parmesan is delicious on frozen broccoli.

The Directions

  1. Add the broccoli to a mixing bowl and top with the oil, sugar, and seasonings. Toss to combine.

  1. Remove the baking sheet from the oven, and add the broccoli in an even layer.

  1. Bake for 16 to 18 minutes at 450 degrees F until the broccoli is tender and slightly browned. If you’d like it even crispier, pop it under the broiler.
  2. Squeeze lemon juice over the top. ENJOY!

Roasted Broccoli Seasoning Ideas

  • Garlic Roasted Broccoli. Add 1 teaspoon garlic powder with the other seasonings.
  • Spicy Roasted Broccoli. Add 1/4 teaspoon cayenne pepper with the other seasonings for an extra level of heat (omit the red pepper flakes unless you want it VERY SPICY).
  • Everything Seasoning Broccoli. Add 1 teaspoon everything bagel seasoning with the other seasonings. (If you don’t have a premade everything bagel seasoning, you can make your own by combining 2 tablespoons poppy seeds, 1 tablespoon sesame seeds, 1 tablespoon black sesame seeds, 1 tablespoon dried minced garlic, 1 tablespoon dried minced onion, and 2 teaspoons flaked sea salt. This will make 1/2 cup everything bagel seasoning for you to use however you wish.)
  • Pesto Roasted Broccoli. Toss the broccoli with a few tablespoons of your favorite store-bought pesto, and bake as directed. Add freshly grated Parmesan over the top after baking. YUM.

How to Store and Reheat Roasted Vegetables

  • To Store. Refrigerate leftovers in an airtight container for up to 3 days.
  • To Reheat. Reheat in a 400 degree F oven for 4 to 6 minutes, until heated through. You can also rewarm this broccoli in the microwave until hot.
  • To Freeze. You can freeze roasted vegetables for up to 2 months. Thaw them overnight in the refrigerator, then reheat in the oven.

Recommended Tools to Make This Recipe

  • Baking Sheets. Ideal for roasting any and all frozen veggies and fresh veggies too.
  • Mixing Bowls. These are great for tossing your broccoli with spices and oil.
  • Measuring Spoons. Accurately measure all the spices for your roasted frozen broccoli.
Roasted vegetables and lemon wedges on a plate

We are loving this frozen chopped broccoli recipe so much, I’ve been roasting at least two bags per week. It’s so quick and easy, I may not go back to using fresh when all I need is a fast vegetable side dish (although this Roasted Broccoli is calling my name).

I’m also feeling super jazzed and curious about other frozen vegetables that roast well. I suspect this method would work well for roasting frozen cauliflower without needing to adjust the recipe—you could make a mix of roasted frozen broccoli and cauliflower too. I’ve learned that Roasted Frozen Brussels Sprouts are equally as delicious, and if there’s a different vegetable you’d love to see me tackle, please let me know in the comments below.

How to make roasted frozen broccoli in the oven. This easy method makes crispy frozen vegetables and is such a timesaver. Perfect for fast, healthy sides!

Prep: 5 minutes
Cook: 20 minutes
Total: 25 minutes

Servings: 4 Servings



  • Arrange one rack in the lower third of your oven and one in the upper third and preheat the oven to 450 degrees F. Line a rimmed baking sheet with parchment paper and place the sheet pan on the lower rack while it preheats.
  • Place the broccoli in a large mixing bowl and top with the oil, sugar, salt, black pepper, and red pepper flakes. With a big spoon or your fingers, toss to combine.
  • Once the oven is preheated, carefully remove the hot baking sheet from the oven. Add the broccoli (it will sizzle as it hits the pan) and spread it into an even layer. Where possible, turn the flat sides of the broccoli florets so that they are touching the pan.
  • Return the pan to the lower third rack, and bake until the broccoli is tender and beginning to brown at the tips and edges, about 16 to 18 minutes. If you’d like the broccoli even more crisp, switch the oven to broil and move the pan to the upper rack. Bake for 1 to 2 minutes, until the broccoli becomes even more caramelized.
  • Remove from the oven and squeeze the lemon over the top. Serve hot.


  • TO STORE: Refrigerate leftovers in an airtight container for up to 3 days.
  • TO REHEAT: Reheat in a 400 degree F oven for 4 to 6 minutes, until heated through. You can also rewarm this broccoli in the microwave until hot.

  1. This recipe fails to account for the amount of moisture in these florets, especially if your bag is full of large round tops. I had to drain this after the prescribed bake time and returned it to the oven. If you don’t cut the larger tops after they’ve softened in the oven, they taste like wet socks. This is easier in a non stick frying pan. Takes about the same amount of time. Cover on high until no longer frozen, drain, uncover until they no longer leave a trail in the pan and add olive oil. Minced garlic ect. Toast in the oil a few min.

    1. I’m sorry to hear that you had trouble with this recipe, Michael. I know it’s frustrating to try a new recipe and not have them turn out, so I really wish you would’ve enjoyed them!

    2. Delicious!!!!! I used a lemon flavored olive oil, Trader Joe’s green goddess seasoning + a touch of maple syrup. I took someone’s advice from another comment & added the oil + seasonings straight into the bag of broccoli & shook it up. Definitely will be roasting broccoli this way forever!!! YUMMM!!!!5 stars

  2. I tried this and it was really yummy! It was not as crispy as when roasting raw broccoli but I did not follow the advice of broiling in the upper rack, I will next time. I ate all of it right out of the oven and didn’t share lol. Thanks Erin!5 stars

    1. Hi Dee! I have a slow cooker broccoli cheese soup that is similar to Panera’s but doesn’t need the to have the broccoli cooked ahead of time if you’d like to check it out: Also it would be really hard for me to advise if this can be used in other recipes without knowing the recipe that you are using, but I do think this broccoli is very flavorful and so delicious, even on it’s own! Hope this helps!

  3. This worked well with fresh broccoli tonight. I sliced the large florets in half, peeled and sliced the stems into coins, and used a pinch of brown sugar. The lemon halves were roasted along with the broccoli. Before serving I drizzled the lemon juice over the broccoli. Quick, easy, and tasty recipe – thank you.5 stars

  4. Just like to note that frozen veggies are not bacteria free, which is why you can’t just defrost and eat them raw like fresh veggies, but as long as you cook them at above 165f, then you’re good. Also why you can’t steam frozen veggies out of the bag and must let it sit in the bag for at least 5mins if you microwave them.5 stars

  5. Tried this in a pinch, turned out just amazing. Would never have thought this could work, it’s a game changer. Thank you!!5 stars

  6. Delicious. I am definitely making this again. Most likely as the main course. I skipped the sugar and have no regrets.5 stars

  7. My family loved this recipe and it’s a game changer! The broccoli came out perfectly and the lemon hit was perfect. This will be in permanent rotation at our house. Thank you!5 stars

  8. Dumb question but do you defrost first or use right from freezer. I reread but don’t see this ste

    1. Hi Hillary! I’m sorry to hear you didn’t see it! It was actually listed as the first ingredient in the recipe card! I love this recipe because you do not have to defrost them first! That is the beauty of it! Hope you enjoy it!

  9. I love this recipe! Someone commented about the moisture in the florets. I’ve found that if I buy the store brand, the florets are enormous and there’s tons of extra liquid and this method isn’t ideal for them. But, if I buy a brand name (just grab them when they’re on sale), the florets are smaller, and this is perfect. Thank you so much for sharing!5 stars

  10. Quick, easy and super delicious! So much better than steaming frozen broccoli. I’ll be using this one regularly. Thanks!5 stars

  11. I tried this tonight minus the parchment paper and lemon (I realized I had no lemon after I started cooking), and it was delicious! Next time I think I’ll try mixing broccoli and cauliflower.5 stars

  12. Loved the taste and the texture. I threw some leftover steak on the sheet a few minutes before I took the broccoli out. I used Stevia instead of sugar and red pepper cause I didn’t have the flakes. This is going to be a go to for me. Thank you!5 stars

    1. Hi Lis! So glad you enjoyed the recipe! Thank you for this kind review and feedback on the changes you made! Yum!

  13. I loved your roasted frozen brussels sprouts but the broccoli just did not work for me. Even after broiling a bit it was still no where near the fresh roasted.1 star

    1. I’m sorry to hear that you had trouble with the recipe, Sheila. The method and timing has worked well for myself (and others) but I know how frustrating it can be to try a new recipe and not have it work out, so I really wish you would’ve enjoyed it!

  14. I’m with some of the commenters… I’d blanch the broccoli,that’s frozen for a min or two.. then follow,as written. My broccoli even after roasting was still a bit wet. Tasted good, but needs some adjustment. With raw broccoli I think it could be great.3 stars

  15. Very very good! I think pre-heating the baking sheet is the “magic” in this recipe. I love fresh broccoli oven roasted, but don’t always have that option. This recipe makes the frozen broccoli taste like I roasted fresh broccoli. Yum, yum, yum!!!5 stars

  16. I tried this this afternoon, just for myself, lol old but not yet daft, I was cooking salmon darnes in my recently aquired air fryer, I was matching the salmon with steamed baby new potatoes, frozen peas and trying the frozen broccoli also in the air fryer, sadly , I blame it on my advancing years I ommited at the start, tossing the broccoli in the extra virgin olive oil and as I plated up I forgot to sprinkle with lemon juice. However the resultant dish was very enjoyable, Ok the oil and the lemon juice were badly missed. I will however try this again,` but will atempt to make sure and switch on my sadly geriatric 82 year old brain !!!

  17. This is excellent and I might never fix frozen broccoli any other way. I added red bell pepper 1 inch squares, baked for 15, flipped all and baked 4 more minutes. I seved it with garlicky pasta Alfredo and what an excellent, easy, quick meal it was!5 stars

  18. I’m not sure what was wrong but I followed the recipe exactly and the broccoli was mushy. The only thing I wonder is could it make a difference that I used the steamable broccoli florets. Very disappointed since it was a Thanksgiving dish.1 star

    1. Katherine, I am so sorry to hear this was disappointing. Frozen broccoli is definitely more of a shortcut weeknight side than holiday worthy dish, as it just can’t get as crisp as fresh. Regardless, I know this is a huge bummer. I wish it would have turned out better for you.
