Oven-roasted frozen cauliflower is a delicious side dish worthy of any meal. It's got a nice crispness, softness, flavor, and appearance, making it perfect to sit next to your chicken, meatloaf, or pasta dishes.
Cooking frozen cauliflower in the oven is my favorite way to do it. In the microwave steamer bags the end results are usually hit or miss and flavorless but on a baking sheet I can cook it on the rack next to my main dish and have them finished at the same time and both full of flavor.
We love eating oven roasted frozen cauliflower so much that we eat it about once a week following the recipe below. Check out how to Roast Frozen Green Beans if you're looking for some more frozen veggie side dish ideas!
Why This Recipe Works
- It's flavorful. The chicken broth adds a great flavor to the baked frozen cauliflower as it cooks, but of course, using vegetable broth would work, too, if you want to skip the meat products.
- It's easy. Just toss it all on a baking sheet and let the oven do its thing.
- It's a nice change of pace. All too often, frozen veggies are simply steamed and left unseasoned. There's nothing wrong with this, but a little change of pace is always nice.
🥘 Ingredients
Frozen cauliflower- For this recipe, grab a bag of frozen cauliflower. Any brand will work. You want the bag to be about 12 ounces in size.
Seasonings- You will need Black pepper, Salt, Garlic powder, and Onion powder for flavorful veggies.
Chicken broth- This is an optional ingredient, but it's one that I have discovered truly makes cauliflower taste incredible.
Olive oil- Adding olive oil will help the seasonings to coat the frozen cauliflower so that they're all delicious.

🍴 Recipe Tips
Different temps, different speeds
This cauliflower can be cooked slower at 350 degrees or a little faster at 450 degrees. This gives you a perfect chance to cook it alongside your other oven-baked dishes without needing to extend the wait time and drag dinner out a little longer.
Easier clean up
Everything for this recipe is tossed together on a baking sheet, so there is no need to dirty additional dishes. While the pan will be fairly simple and easy to clean, laying parchment paper or foil down will greatly help in reducing the cleanup.
Thawing not needed
Also, it's worth noting that you do not need to thaw the cauliflower beforehand. Just open a bag of frozen veggies and toss them on the pan while still frozen. Maybe break up a few chunks if they're too large, but other than that, this recipe is super simple!
💭 FAQs
Absolutely! We like to double the recipe below because we just can't seem to get enough of it. I mean, how often do you get kids to WANT to eat extra veggies? Doubling or tripling the recipe will not increase bake time as long as the cauliflower is nicely spaced out and not piled up too much.
You can keep the leftover cooked frozen cauliflower in an airtight container in the fridge for up to 3 days. Just reheat before eating.
If you overcrowd the baking sheet with frozen cauliflower, the moisture that they will leave behind as they thaw and cook will be absorbed by one another. This means that they can become mushy if too much moisture is absorbed. To avoid this, limit the additional liquid by not overcrowding the pan.
