Ingredient Checklist


Instructions Checklist
  • Preheat the oven to 400 degrees F (200 degrees C).

  • Place cauliflower, potatoes, and onions into a 9x13-inch glass baking dish and sprinkle rosemary over the top. Season liberally with salt and pepper. Add olive oil and toss vegetables until evenly coated.

  • Roast in the preheated oven, tossing halfway through, until evenly browned, about 1 hour. Remove from the oven. Add lemon juice and toss with a metal spatula, scraping any browned vegetable bits off the bottom. Allow to cool.

  • Fill blender halfway with roasted vegetables and add 2 cups stock. Cover and hold lid down with a potholder; pulse a few times before leaving on to puree. Pour into a big soup pot. Repeat with remaining vegetables and stock.

  • Heat soup over medium heat until it boils. Season with salt and pepper to taste.

Cook's Note:

Before serving you can add more stock or water to thin the soup out if necessary.

This was ok, but it has potential! I felt like it was missing something. I would add some garlic and additional seasonings for more flavor, as I could barely taste the rosemary. Serving it with seasoned croutons really helped provide additional flavor, as well as a nice crunch factor. Ovens do vary, but I found the roasting time to be too long; 40-45 mins was plenty.
