3 cheese roasted cauliflower tomato soup, seriously our new favorite fall soup

It has happened. All of these years of picking our cauliflower out of those costco veggie bags (what’s it called? Normandy mix?) we’ve finally found a way to fall in love with the stuff. In fact, I wonder if I could use frozen cauliflower for a 3 cheese roasted cauliflower tomato soup? No? I’ll have to experiment. And I feel just awful but I didn’t do any pretty pics. Sorry. I just was so surprised by it’s taste and was losing light fast so I had to hurry and snap a photo.

The other day I asked if any of you liked cauliflower soup after noticing how many people search for roasted cauliflower. I mean, where was I all of these years? I thought everyone ignored the white stuff. I for sure would have if I was a pioneer and saw it. Anyway, I also started hearing rumor that people eat something called Wisconsin Cauliflower Soup at Cafe Zupas and I couldn’t help but be intrigued.

I mean, these were people I totally trust about food and yet they were actually pureeing and EATING cauliflower? Had they gone crazy or was I living in a hole? And that’s where you all come in. We stinking love our readers. Your advice is always awesome and you all totally love eating like we do. So I asked, you answered and the verdict was in. Cauliflower soup is a must try.

And then I doubted. I started to get nervous that it couldn’t possibly be wonderful made from something so bland. So I doctored it up. We love our roasted tomato soup and happen to think it’s the best ever, so I prepped the cauliflower to be roasted. And that’s when I noticed the four sad roma tomatoes. Surely I should add those, right? So then if you’re going to add tomatoes why not roast a little garlic, yeah? We got it all on the pan, and cooked it to perfection, blended everything together and then since I was already getting crazy I threw in 3 cheeses, fontina, colby jack and parmesan. And it was creamy, delicious, perfection. And even Cade said, “New favorite soup! I can’t stop eating it!” So my darlings, it’s your turn to make it and report back to me.
