Baked Cheesy Cauliflower Casserole is like eating cauliflower mac and cheese, only instead of pasta as in the “mac,” it’s packed with only cauliflower! Super easy and impossible to mess up. This low-calorie, Keto-friendly, gluten-free casserole is creamy delicious, and it makes a wonderful side dish that’s loaded with nutrients!
I mean, how many ways can we make cauliflower?
We buy cauliflower weekly. So when it comes to dreaming up different ways to make it for my family, it’s not easy.
Every so often I make my girl’s favorite cauliflower dish: my pasta with creamy cauliflower, and my luscious potato-cauliflower soup.
But since my girls have been home for the past few weeks, they requested some low-carb, gluten-free dishes for dinner.
So when I was craving some comfort food, like mac and cheese (but I was voted out), I decided to make this baked cheesy cauliflower casserole instead.
Baked Cheesy Cauliflower Casserole is so simple, super easy, and TOTALLY delicious!
This cauliflower dish turned out better than I had expected and it serves four people.
If you need more servings, you can easily double all the ingredients, and it’s worth it. Leftovers turn out great too simply because it reheats beautifully.
For this recipe, you will need:
one small head of cauliflower
a few seasonings
How To Make Baked Cheesy Cauliflower Casserole (full recipe card below).
This recipe couldn’t be easier!
1. First, cut up the cauliflower, cutting the florets, and discard the cord. Then give it a good rinse. Next, in a medium-size pot, toss in the florets and pour water up to one inch.
2. Cover with a lid, and bring to a boil. Then lower the heat and simmer the cauliflower for one to two minutes. Turn off heat. Drain water and return back to the stove, cover with a lid, and allow the florets to steam for 2 to 4 minutes, until fork-tender.
3. Transfer cauliflower to a baking dish.
4. In the meantime, make the cheese sauce. In a small saucepan, pour in the cream, then add in the mustard, seasonings, and cheddar cheese. Simmer until the cheese melts and the sauce thickens.
5. Pour the cheese sauce directly over the cauliflower. Then bake in the oven for 15 to 18 minutes, until the cheese sauce is bubbling and cauliflower is golden on top. If you prefer, you can broil in the oven for a few minutes to brown the top.
Cook’s Notes and Tips!
You can adapt this recipe and use a blend of shredded cheeses to your liking.
Can we use frozen cauliflower florets? I haven’t yet but I’m sure it’s fine.
You may add additional seasonings to your liking, try a splash of smoked paprika.
If you don’t have heavy cream, you can use 1 cup of milk or almond milk, and whisk in 2 teaspoons of flour (or GF flour), and simmer until the sauce thickens. Then add in the shredded cheese and stir until the cheese completely melts.
Don’t forget to scoop up some of that delicious cheese sauce on the bottom of the baking dish and drizzle it over each serving. It’s the best!
FOR INSTANT POT…
To make in the instant pot, you will need to rinse, cord, cut the cauliflower.
Add cauliflower with 2 to 4 tablespoons of water.
Then cook on the “Manual” setting for 5 minutes.
Stir in remaining ingredients. Leave on “keep warm” for about 10 minutes.
Stir and repeat until melted, creamy, and heated through.
If you prefer, you can transfer everything to a baking dish and broil it for a few minutes to brown the top.
