I can’t tell you how many times I have made this Twice Baked Cauliflower lately, but it has been more times than I can count. I got the inspiration for this recipe from Kalyn, at Kalyn’s Kitchen. She is one amazing low carb food blogger. Everyone around me has been on a keto diet, and sometimes you just miss old favorites like mashed potatoes. I am not one for saying something tastes like something else, I want it to taste close. I really think you can turn cauliflower into a good substitute for mashed potatoes when you mix in a few more ingredients.

For this recipe, I steam the cauliflower, in the video, I show you how to do this with an Instant Pot. You can steam cauliflower in your favorite way, that could be with a steamer, or perhaps you will want to dig around in your pantry for the steamer insert that came with your pot and pan set.

How to make cauliflower creamy

For me the real secret in this recipe is overcooking the cauliflower. If you overcook it until it is soft, it will have the texture of potatoes without all of the carbs. So normally I steam vegetables for about 4 to 5 minutes in my pressure cooker, for this one, I steam 7 minutes when I want the cauliflower to be extra smooth and creamy.

What to mix into Twice Baked Cauliflower

You can mix in a variety of cheeses, some chopped onions or chives, bacon, and you can play around with your spice and herb blends. I love a smoked cheese in here, it really adds something extra to the recipe.

  • Mix with a blender until smooth.  Place in a 2-quart casserole dish and top with additional cheese and bacon.

    I am just learning about the keto diet this week. my surgeon suggested I do this to prepare for an upcoming procedure. to say I am overwhelmed is an understatement. Your recipes are awesome and I appreciate your guidance along this learning journey. Love cauliflower and spaghetti squash and am so happy to see they are approved to eat. thanks you so much!
