Winter is coming. And with winter weather approaching I’ve already started making casseroles and roasts and soups and stews. To me there is nothing better than a good cheesy casserole to warm your hearts and bellies on a cold winter day.

However since I like to keep the carbs down, I forgo the rice, pasta and potatoes and use substitutes. I still use the cream, butter and cheese though! Especially in this creamy, low carb cheesy cauliflower casserole.

Spray a baking dish with cooking spray.
Place a layer of cauliflower then the cheese, green onions and salt and pepper.
Repeat layers but on the top pour the cream and then end with the rest of the cheese.
Bake until brown and bubbly.

What type of cheese to use in this low carb casserole

For this keto cauliflower casserole I like to use Gruyere cheese. Aldi now has it almost all the time but if you can’t find it, try Swiss cheese. Along with the heavy cream the Gruyere has a special taste that sets it apart from other casseroles.

This cauliflower casserole is so flavorful you won’t miss the potatoes.

Use either a muffin tin or baking dish

The first time I made cauliflower casserole I did so in a muffin tin and they were soooo good. However they looked terrible and since I had enough time, I remade them in a baking dish. And while they were very good, I liked them better in the tins.

In the tins they get all brown and crusty around the sides and I personally find that part to be the tastiest. So if you really want them more crispy try a muffin tin, however note they can be a real pain to clean.

I love gruyere or Swiss cheese for this keto casserole. It works so well with cream and green onions.

Today, though I am sticking to the baking dish. The most recent time I’ve made these I just made them in the baking dish above. I increased the cooking time and I got all that good crusty parts on the top.

Now let’s get to the recipe. I used a mandoline like this to cut my head of cauliflower into thin pieces to make it layer more easily. You can just use a knife if you wish. Try to cut them evenly though.

Once you have your ingredients lined up (cauliflower, cheese, salt, pepper, green onions and cream) you start to layer them. Remember to spray your muffin tins or baking dish first. Start with the cauliflower, then the cheese, green onions and salt and pepper.

I only used salt and pepper on one layer in the middle. Then repeat layers but on the last layer, add the cream before the cheese. Bake until golden and delicious!

Is this a keto casserole?

If you are following a keto diet as opposed to a low carb diet the macros for 1 serving of this cauliflower casserole is: 81% fat / 14% protein / 5% carbs which I would consider this a keto casserole as well as low carb.

This cheesy casserole is very rich so a large baking dish makes a lot. You only need a small amount to be satisfied. This will be great for the fall and winter months. It’s pure comfort food if you are on a low carb diet and even if you are not.

We ate it as a side dish with a nice pork roast and it was the perfect side dish. Here is the nutritional information per serving:

cals 280 / fat 24g / carbs 3.6g / fiber 1.8g / protein 9.4g – net carbs = 1.8g per serving
