Frequently asked questions
It all depends on whether you are baking a whole cauliflower or using cauliflower florets. A whole cauliflower will need 40 minutes or so to bake fully until it is fork-tender. Cauliflower florets need 25-30 minutes of baking in a 375-400 F preheated oven. It is always best to use your fork to check for doneness. Also, it cut down on baking time, consider steaming the cauliflower for a few minutes in some boiling water before adding it to the oven. This is certainly an option and not necessary.
Place leftover baked cauliflower in a tightly sealed container and store in the fridge for 3-4 days. We do not recommend freezing this cheesy baked cauliflower because it will be a bit watery and soggy. But if you must, they last up to 3 months in the freezer, thaw in the fridge the night before and reheat in the microwave and enjoy.
This cheesy cauliflower casserole makes for a great side dish to a variety of main courses. Serve it with any grilled protein like chicken or salmon, try it with roast beef, roasted whole chicken, shrimp, or kabobs.

Notes
- If you prefer to skip roasting the cauliflower first and save time by cooking everything in one dish, place the cauliflower first in the baking dish you will be using, then after it is cooking just pour in the prepared cheesy sauce.
- Cut the florets into smaller even sizes to ensure they all bake through,
- Consider adding in broccoli too if you like.
- Any milk of choice works.

Hi! Can you use frozen cauliflower for this recipe?
Rena Awada says
Yes you can
Melinda says
This recipe was super yummy and my husband and I enjoyed it. However, there were some things I found in the recipe that were confusing and you might want to edit….
1. In #3 when it said to season with salt and pepper, I just put a random amount. However, later I realized that you had suggested amounts in the recipe! If #3 said “with THE salt and pepper,” we would know to look at the ingredient list.
2. In #7 when it says to stir in the cheese, I assumed that meant ALL the cheese, but then I saw in #9 that I was supposed to save the parmesan! To fix that, #7 should specific that it’s just the cheddar going in.
3. On a practical note, why does there have to be two separate baking dishes? Why can’t the cauliflower be baked in the baking dish from the beginning, and then the sauce added on top?
Again, thanks for the recipe! Hopefully the feedback is helpful 🙂
Rena says
Hi Melinda. I can see where it is confusing about the cheese. I did fix it just now. Hope this helps.
Pat says
Have made this this several times. Is always a hit. Can this be made ahead and cooked next day
Rena says
Yes! We love it too
Alison Coen says
If you make ahead, which step do you save for the next day? Cook the cauliflower and add the sauce but bake the next day? Does that make it soggy?
Rena Awada says
yes. that would be ideal
Grace says
