Recipe notes

You can buy cauliflower whole from the grocery store, or you can purchase bags of cauliflower florets.

If you want to make this keto-friendly, leave out the flour and substitute heavy cream for the milk.

What to serve this cheesy cauliflower bake with

I suggest serving this side dish with comfort foods such as smoked chicken, baked ham, or pork ribs. Honestly, even a homemade sloppy joe or kielbasa sausage tastes amazing with it, too. There are so many routes you can take.

Pair it with other sides, too: mixed salad, glazed carrots, creamed corn, broccoli salad, or baked beans are all top-tier accompaniments.

How to store leftovers

If you plan to eat it the next day, you can keep the baked cauliflower in the same baking dish that you cooked it in. Make sure to tightly wrap it with foil once it cools and move it to the fridge. Otherwise, I suggest transferring it to an airtight container.

How long does baked cauliflower with cheese last?

This side dish will last 3-4 days when you properly store it. Leftover portions can be frozen in an airtight container for up to three months.

What is the best way to reheat this dish?

For the best texture and taste, I would reheat this dish in the oven! You can cover it while you warm it up to prevent the top from burning. Add a splash of milk if needed. Reheat it in a 350°F oven until it is thoroughly heated.

Individual portions can be heated in the microwave. Cover it and stir it every 45 seconds until it is hot.
