“Cauliflower is nothing but a cabbage with a college education.” ~~ Mark Twain, via Food Lover’s Companion.

An elegant head of cauliflower tucked in our fridge crisper drawer inspired this simple silky-rich vegan soup. For color, contrast, and crunch, we give each bowl finishing sprinkles of toasted pumpkin seeds, sliced green onions, and cilantro leaves.

This healthful soup is more brothy than thick. If you prefer a thicker soup, you’ve got a few options. One is to include peeled potato chunks along with the other vegetables. You could also add cooked white beans–not only will the beans give this soup a creamier texture, they’ll bump up the protein ration. And the easiest way to give your velvety pureed cauliflower more body is to reduce the vegetable broth from 5 cups to 4.

If your kitchen sports a couple of worthy time-saving tools, you can make this soup in half an hour. A pressure cooker, stove-top or the electric Mealthy or Instant Pot, and an immersion blender, are the best speed tools I know for smooth creamy soups.

Know that you can make this soup without a pressure cooker. And of course you can puree it in a regular blender. Without those time-savers, it will just take a little longer. You’ll find directions for both pressure cooker and stove-top Southwestern cauliflower soup in the recipe card below.

Make this soup your own–this easy recipe offers plenty of riffing possibilities. One day sub in cauliflower’s cousin broccoli. Another, add a sweet potato and a carrot along with the cauliflower and season the soup with curry powder instead of cumin.

To make this soup in your pressure cooker, sauté the aromatics first, then add the caulflower, chiles, and broth. Lock the pressure cooker lid in place and bring to high pressure. Maintain the pressure for 6 minutes, then quick-release the pressure. With an Instant Pot, you turn the top dial to vent, for a stovetop pressure cooker, place the pot under cold running water until the pressure valve drops.

As I mentioned, a hand-held immersion blender (Affiliate) makes it easy to puree creamy soups. Really, especially if you make a lot of soups like we do at our house, an immersion blender is a very handy kitchen gadget, in my mind practically essential. Simply stick that wand in the cooking pot and whir until you’ve got smooth, creamy, no muss no fuss, lickety-split soup. All you do is keep moving the hand blender up, down, and around the pot until no chunks remain.

I mean, have you ever tried to liquefy hot soup in a regular blender jar? Don’t try to puree the whole batch at once, it’s just about impossible to hold the lid on tight. The heat/steam pushes the lid off, the hot soup splatters everywhere, on your clothes and all over the kitchen counter. You have a big cleanup situation. If a jar blender is all you have, be safe–blend in small batches, transferring the pureed soup to another pot as you go.
