Cauliflower really is a magical vegetable. It can replace pizza crust, chicken nuggets/wings, rice, pasta, and potatoes. The first time I had mashed cauliflower was over a decade ago and it was quite watery – not the most appealing substitute for potatoes. But this Instant Pot version results in a thicker consistency more closely related to mashed (whipped) potatoes.

To make this, you steam the florets in broth, chicken or vegetable depending on your preference, along with garlic. Once cooked, make sure you drain all the liquid (I know it seems like a waste so if you wan to save it for soup be my guest) and then blend the garlic and cauliflower together. After that you simply add a little sour cream, butter, and salt and pepper to taste.

Chicken with Mustard Cream Sauce December 30, 2022 - 11:55 am

[…] For the many of you who will be partaking in resolutions of healthier eating in 2013, make this chicken NOW or be prepared to cheat a little on that resolution. Not only is there heavy cream in the mustard sauce, but brandy as well. To make it even better, it’s all made in one skillet in under 30 minutes. It’s pretty much impossible to resist. As such, I like to serve this with a side of roasted vegetables and maybe mashed cauliflower. […]
