This easy roasted frozen cauliflower is the answer to trying a new vegetable side dish this week!

Frozen roasted vegetables are my go to side these days. 

I already have recipes for roasted frozen carrots , roasted frozen brussel sprouts, and frozen broccoli, so of course cauliflower needed to be next on my list to make! 

Especially with times like we find ourselves in currently, frozen vegetables are an absolute must have. 

My freezer is stocked full of bags of all kinds and it has made dinner time quicker.

The convenience factor cannot be beat. 

When you need a fast and healthy side dish, frozen vegetables are the answer!

how to make roasted frozen cauliflower

You will need one bag of frozen cauliflower. 

If you are feeding more than 2-3, just double this recipe!

One thing I notice is that we always regret not making more.

This roasted cauliflower is so delicious I could have eaten the whole batch myself!

Preheat your oven to 450 degrees. 

Place the cauliflower on a nonstick sheet pan.

Do not allow the cauliflower to thaw before cooking.

Roasting from frozen allows us to get the perfect texture and those delicious crispy edges. 

It’s very important to place the cauliflower straight from the freezer to the tray, with the oven already preheated.

Use olive oil cooking spray to generously coat the top of the cauliflower. 

I always suggest cooking spray when preparing frozen vegetables, as it is much easier to make sure everything is well coated.

Once the cauliflower is sprayed, sprinkle on even amounts of salt, pepper, garlic powder, and onion powder. 

No need to stir, just sprinkle so that it is all evenly covered. 

Place the cauliflower in the preheated oven and cook for 15 minutes without touching it. 

This will help the cauliflower edges crisp up!

After 15 minutes, remove the pan from the oven and stir/flip the cauliflower. 

Spray the cauliflower again with a light layer of olive oil cooking spray, then sprinkle powdered parmesan cheese over the tops of the florets. 

Roast for an additional 5-10 minutes, until the cauliflower is browned with crispy parmesan edges!

The recipe is simple, but it’s all in the method! 

This cauliflower was the favorite food on my plate. 

Roasting cauliflower without any fuss and no chopping required is perfect for busy nights (or for when you are cooking dinner for what feels like the 100th night in a row). 

Try making this for dinner and let me know what you think!

Very tasty - I didn't have olive oil spray so I put a little olive oil on the bottom of the pan and used regular spray over the top. I just used salt and garlic powder, with the hit of parm. Really enjoyed it and happy that it didn't get mushy.

I was skeptical of this working, but it turned out great! I just used olive oil, salt and pepper and didn't even flip because I forgot. We've been burned by so many supposed 4-5 star blog recipes lately that just turn out to be blah. I'm happy to say this is a winner. Thank you for introducing us to a new way of making easy veggie side dishes!

Soooo good! I love the convenience of using frozen, I tend to buy whole ones and forget to use them.... I used shredded Parm and it made great crispy chips... thank you!
