Roasted Cauliflower Potato and Beet Soup
But as for this irresistible soup, inspiration came from the farmer’s market tables piled with fall and winter produce. There was also a stand with micro greens, pea shoots and beautiful radishes that made for the perfect garnish.
I started off by roasting the beets separately from the cauliflower, potatoes, onion and garlic since they would take much longer to become tender. As a shortcut, you can buy packaged beets already roasted but I found the pigment isn’t quite as intense. Plus I love having roasted beets on hand so I’ll roast a bunch, slice and freeze them.
The veggies simply get a good drizzle of olive oil and a generous sprinkling of spices before heading to the oven. You can see how the color intensifies after roasting in the photo below.
What if you can’t find purple cauliflower and potatoes? No problem! Purple sweet potatoes are an obvious alternative, and you can simply use white cauliflower and potatoes as well. The soup will be less purple and have more of a magenta hue from the beets adding the only color.
Tip of the day – when working with hot liquids, do not fill the blender or processor bowl more than halfway, and allow room for steam to escape.
You can ladle the soup into bowls as a main course or ‘soup course’, or in shooters if serving a crowd. No matter the serving size, have fun garnishing! I used radishes, cauliflower florets, pea shoots, sesame seeds and coconut cream to keep it vegan. Enjoy!
