Cauliflower Casserole Recipe

Easy baked cauliflower dish

This simple side is equally great to accompany any low key weeknight meal or fancy holiday feast. Many people say it tastes like mac and cheese!

My family serves it every year next to the sweet potatoes, green bean casserole, mushroom gravy, and cranberry sauce for Thanksgiving dinner, and it’s perfect for Christmas or Easter too.

For a loaded baked cauliflower casserole, sprinkle with bacon bits (some brands are surprisingly vegetarian) and diced chives or green onions.

Or turn it into a main course by adding your favorite protein source before baking. Some people like chicken, sausage, or ground beef, but as a vegan I use chickpeas.

Boiled Cauliflower

Healthy cauliflower casserole ingredients

The cauliflower: The dish calls for seven cups of chopped florets, which is about one medium to large head. I recommend buying a large cauliflower head to ensure it will yield enough. Or for a quick option, you can use frozen cauliflower florets if you prefer.

For the cheese: Cheddar, mozzarella, or a four cheese blend are all fine to use in the easy casserole recipe. Use vegan cheese shreds for a vegan casserole. I like Follow Your Heart brand, which melts like real cheese.

The milk: I used unsweetened almond milk. Feel free to go with whatever type of plain milk you have on hand. Because the dish is a savory recipe, it’s best to not use flavored or vanilla milk or one with enough added sugar that it tastes sweet on its own.

Oil free options: If you use full-fat canned coconut milk, or if you go with the cream cheese option, the dish is rich enough on its own that you can omit the oil. Tahini can also be subbed as long as you don’t mind the strong flavor. Or the oil can be left out completely; the healthy casserole flavor will just not be as rich and full-bodied.

Flour options: All purpose white flour, spelt flour, or whole wheat flour can be used. For a keto cauliflower casserole, use almond flour. I haven’t tried the recipe with coconut flour or cornstarch, so be sure to report back with results if you experiment.

Baked Cauliflower With Cheese

Keto cauliflower casserole

If you want to make a keto casserole, or even if you’re not on a low carb diet and simply want a cauliflower casserole with cream cheese, substitute one third cup of cream cheese (or vegan cream cheese) for the flour.

Use a dairy free and sugar free milk option, such as unsweetened almond milk or cashew milk, macadamia nut milk, or full fat coconut milk.

The keto version of the recipe will have just 1 gram of net carbs per serving.

How to make a cauliflower cheese casserole

If using frozen cauliflower florets, be sure to defrost and fully thaw them first. Pat dry, discarding the extra water.

Optional cream cheese should also be softened if using. Let it come to room temperature so that it’s smooth and easily stir-able.

Only if using raw fresh cauliflower, boil a pot of water. Once boiling, throw in the florets and cook, covered, for 5 minutes or until just tender. Drain.

Spread the cauliflower into an 8×8 baking dish, and set aside. Preheat the oven to 425 degrees Fahrenheit.

For the cauliflower cheese sauce, start by sautéing the garlic in the butter or oil for about a minute. Stir in the milk and salt.

Add the flour or the softened cream cheese, stirring constantly until it thickens and no lumps remain. Remove from the heat.

Add one cup of the shredded cheese to the mixture, reserving the second cup. Stir until it smoothly melts into the sauce.

Pour over the casserole pan, and stir to evenly coat the cauliflower. Sprinkle the remaining cheese on top.

Bake on the oven’s center rack for 30 minutes or until hot and bubbly. Serve and enjoy.

Whole Cauliflower

Make ahead and storage tips

Keep leftovers in a covered container in the fridge for 3-4 days. They can be reheated in the microwave or oven.

If you’re bringing the recipe to a party, it can be made ahead of time and stored in the refrigerator overnight, covered. Reheat in the oven once you arrive at the event.

To reheat in an oven: Preheat to 350 degrees Fahrenheit. Cover with tin foil to prevent moisture loss. Bake the casserole 20 minutes or until hot all the way through.

While you technically can freeze this cauliflower dish, the texture is much better if you don’t, due to cauliflower’s high water content and the creaminess of the vegetarian casserole sauce.

The cruciferous vegetable is a good source of numerous vitamins.

A single cup of chopped cauliflower contains fiber, potassium, magnesium, manganese, phosphorus, vitamin K, folate, and over 75% of the RDI for vitamin C.

Cauliflower is a keto friendly vegetable and is often used instead of carbs such as rice or pasta to lower the calories and carbohydrates of a recipe. It is considered a free food or zero points food on Weight Watchers.

One serving of this cauliflower casserole contains around 5 grams each of protein and fiber, with little saturated fat and no added sugar. It’s also high in calcium.

    I love cauliflower and look forward to trying that recipe! Quick question: would you recommend greasing the baking dish before you put the cauliflower casserole in it?

    • CCK Media Team says

      We never have, and have never found it’s needed. But of course you can and that wouldn’t hurt anything. So either way!

  2. Misha says

    This was easy to make and delicious. I used shredded cheddar and mozzarella for the casserole recipe. Absolutely one I will make again.

  3. Larissa Stevenson says

    5 stars
    Absolutely awesome! I am going to be adding it to my list of meals that I make on a regular basis, thanks for the great recipe! (:

    I have been making this since the early 80’s and used my sister’s recipe which is similiar to yours. I use Swiss Cheese instead of cheddar. I make a white sauce with 2 tbls butter, 2 tbls. flour , 1 tsp of Worcestershire Sauce, 2 tbls of white wine and use Lactose Free Milk for my husband’s tummy. We do not have children so this is a great way to add depth and complexity for adults or a dinner party.

    This was unbelievably good (and so simple to make)! I got ~3 servings from this and enjoyed each one.

    Haven’t tried, but am looking forward to making this as it looks amazing. Just wondering (sorry if I missed it) what is a serving size?

    • CCK Media Team says

      Hi! It makes 8-10 servings. We haven’t actually measured out what that looks like in cups so will have to make it again!

    This Cheesey Casserole was absolutley devine. I loved how rich and creamy it was. I loved the rich flavor of the cheese, and the hearty flavor of the cauliflower. I would definitely recomend this dish to anyone who loves the rich and creamy flavor of the cheese mixed with the soft healthy tang of the cauliflower. It honestly was just a wonderful blend between the two flavors. I would highly recomend.

  8. Sharon Main says

    I just made this and, even though it tastes good, it came out watery. I don’t know what I did wrong.
    I steamed fresh cauliflower and used the cream cheese instead of the flour.
    Also freshly shredded cheddar cheese. The cheese nor the cream cheese wasn’t melting like it should on the stove.
    The only thing I can think of is I used generic cheese (and maybe should have used flour instead of cc).
