Roasted Cauliflower Soup with Vitamix

Mike and I recently decided to clean out our kitchen cabinets. Have you done this before? It was a mess! We found ourselves asking, “Why do we have sooooooo much stuff?

When it comes to being organized, I like to keep it simple and not have so much stuff. We decided it was time to get rid of things we never use or don’t need anymore. It has made such a refreshing difference in our kitchen and with our everyday cooking.

INTRODUCING THE VITAMIX A3500

The main reason we could finally get rid of a lot of things that we don’t need anymore is because of my new Vitamix Ascent 3500. This machine replaced three kitchen gadgets. We no longer need our regular blender, our food processor or our immersion blender. I couldn’t bring myself to throw out my immersion blender yet, but probably don’t need it anymore. The Vitamix handles it all and getting rid of the food processor and old blender has cleared up so much space in our cabinets!

I’m going to share some fun facts about my new kitchen toy so you can see if it might be something worth having in your own kitchen.

THE VITAMIX GOES BEYOND SMOOTHIES

Seriously, this VitamixRoasted Cauliflower Soup Recipe | Regan Baroni (4) helps me make a wide variety of recipes. I used to think of the Vitamix as just a fancier, much more expensive blender. But, I can make so much more with this machine than I ever could with our blender… it just goes beyond smoothies. You can make chunky salsas, velvety-smooth soups and… wait for it… perfectly mixed dough for homemade pasta or pizza dough. I never would have thought to make homemade dough with a Vitamix. How cool is that?

VELVETY SMOOTH TEXTURES

Because I’ve been on a huge dairy-free soup kick lately, I have to talk about the texture of my soups while using the Vitamix. It creates the smoothest, creamiest textures because of the super powerful blades. And, although I hung on to my immersion blender, I haven’t had to use it all.

VARIETY OF SPEEDS

This machine will blend up or chop anything you want in about five minutes. The fact that it’s so fast has helped me create multiple recipes back-to-back with ease. There’s also custom program settings that let you set it and walk away until it’s done blending. The pretty digital touch screen display also provides a countdown for you, so you know how much time the custom settings will take.

EASY STORAGE

I will say that this is a large machine. But, the good news is, it’s only two pieces! This makes it easy to take apart and store if you don’t have the counter space for it. I’m leaving mine out on the counter for now. The stainless steel and digital touch screen look beautiful and everyone who stops by asks about it. I think the Vitamix has definitely elevated my cooking game.

THE RECIPE

Amongst all the soups I’ve been making, this roasted cauliflower soup recipe might be my favorite in comparison to the Gingered Carrot Soup that I shared earlier this month.

Happy Cooking!
