There are tons of low carb mac and cheese recipes using cauliflower on the interwebs these days. You can’t browse Pinterest for more than a minute or two without running into at least one. Yet I’ve been blogging low carb recipes here on IBIH for over 3 years and have never posted my own version!

That travesty ends today, for I give you this totally crave-worthy faux mac and cheese recipe, which contains not only the ubiquitous cauliflower, cream, butter, and cheese – but also some spicy Chorizo, earthy green chilis, and a pop of fresh cilantro!
The resulting recipe is a delicious and hearty casserole that comes together in less than half an hour! Perfect for a busy weeknight, this recipe also reheats well for the week’s lunches (if it lasts that long!)

Description
A hearty and delicious Keto Mac and Cheese recipe made with cauliflower instead of pasta. Low Carb and Gluten Free.
Ingredients
- 4 cups raw cauliflower florets
- 1/4 cup heavy whipping cream
- 2 tablespoons butter
- 2 tablespoons chopped canned green chilis (mild)
- 4 oz Mexican Chorizo (you’ll cook and use 1/3 cup for this recipe)
- 1/2 cup shredded sharp cheddar cheese
- 1/8 teaspoon kosher salt
- 1 tablespoon chopped fresh cilantro
Instructions
- Spread your cauliflower out in a microwave safe casserole dish. Microwave for 10 minutes or until partially tender.
- Meanwhile, cook your Chorizo in a small saute pan and drain off the extra fat. Measure out 1/3 cup of the cooked Chorizo for this recipe and reserve any extra for another use.
- Remove the cauliflower from the microwave and stir in the heavy whipping cream, butter, chopped chilis, cooked Chorizo, shredded cheddar, salt, and chopped cilantro.
- Once it’s fully combined, bake in a preheated 375 degree (F) oven for 15 minutes or until the cauliflower is fork tender and the cheese is melted and bubbling. Serve hot.

I have nothing but kudos for this recipe. I’m not a huge fan of cauliflower, but after being diagnosed as a Type 2 diabetic several years ago, I’ve had to find ways to incorporate this super low carb veg into my meals. So far, this recipe is my favorite, for several reasons. The first reason: I really like the way it tastes. No, it is not like mac and cheese, but I truly found it flavorful, delicious and very filling. One pan of this dish has provided me with three meals. Second reason I like this recipe so much is it is inexpensive AND quick and easy to make. Third reason, which should really be the first: I got excellent BG readings after eating this.
When I made this dish, I steamed fresh cauliflower. I didn’t see the note about letting the steamed cauliflowr drain well before using, but it really didn’t negatively impact the final dish.
I also substituted two TBSP of mild salsa for the green chilis, because that is what I had on hand. Otherwise, I did follow the recipe.
Thanks again for the receipe. I know I will be adding this into regular rotation all this fall and winter.

I’m making this tonight to prep for my lunches at work this week! Cauliflower is teely expensive here right now and at Costco in Canada we don’t get everything that the states do, so I was super pumped to find cauliflower rice at Costco today! I’m going to attempt this recipe with cauliflower rice instead of florets and see how it turns out. REALLY looking forward to it!
Kendra says
Oh the typos and poor grammar – I’m usually better I promise hah
Becky says
Do you think this could be frozen and reheated?
Mellissa Sevigny says
Definitely!
Sherry says
Is there any way I can use frozen cauliflower in this recipe?
Belinda says
I made this tonight and it was very good! I doubled up on the green chile and used HOT ’cause I like it like that! It really wasn’t a whole lot like mac ‘n’ cheese but it was even better being low carb. Going to be a regular dish around here!

This comment made me laugh out loud Carlie, thanks! That last part made me envision “Phteven” under(bite) dog from Pinterest meme fame!
Carlie says
Ha haaaa! I’m glad you enjoyed my comment, ’cause I certainly enjoyed that mac n’ cheese, girl!
I had seen that dog before, but did not truly understand the root of the meme, and for that, I thank you. You are just enriching all kinds of parts of my life! :D
