This roasted cauliflower Alfredo sauce is a rich and savory sauce with the sweetness from onions and roasted garlic. A healthy but rich take on the original cauliflower sauce. Super simple to make and perfect for creamy Alfredo sauce substitute.
Okay. So, we've all tried to be virtuous and get on the cauliflower Alfredo sauce wagon. But here's the thing. It's kinda gross, right?
Now, I'm a big fan of cauliflower and it's health benefits. But what I can't quite abide is that when so many recipes turn it into sauce, cauliflower becomes a watery/milky and tasteless shadow if it's former self. It's like it turns into a shy and embarrassed version of what it used to be.
So, how do we make this cauliflower the star of it's own show? We roast it. Pure and simple roasting here folks. We toss in a whole white onion for sweetness and a whole head of garlic. But hold up! Hold the heck up! We are not talking a whole head of pungent, a bit too much kinda garlic. You know... the kind where you can't leave the house or speak to anyone in person for a week. Yeah. It's not that kind of garlic. We are talking roasted, soft, caramelised and super sweet garlic.
As soon of that chopped tray of veggie goodness hits the heat of your oven you'll smell that garlic and onion and it will be like heaven.
Okay. So, these three ingredients together to create something that is a near perfect Alfredo sauce. I say near perfect because I always wanna leave room for improvement, ya know.
