The Annual Downsizing.

Is anyone else feeling less than svelte after indulging during the holidays? If we’re like millions of people, our resolutions for the new year call for less food and more exercise.

As we downsize, this soup will satisfy our yearning for filling, full-flavored fare. It keeps well in both the fridge and freezer so keep plenty on hand for fast lunches and light suppers.

Does Vegetable Soup Need Oil? A Taste Test.

This recipe has no added fat – and needs none.

When making it for the first time a long while back, I employed the standard trick to reduce fat while enriching the flavor in soups and stews.

It’s a simple thing, no "trick" really: simply sauté the garlic and onions in a tablespoon of olive oil (typically less than specified) to a deep gold color rather than until pale and translucent, the typical instruction. Doing so releases the onion’s natural sugar and can make a big difference in perceived richness. In fact, I use this very technique in my master recipe for vegetable soup, How to Make Homemade Vegetable Soup.

In this soup, however, side-by-side taste tests yielded no difference at all.

  • In Pot One, I threw in all the ingredients, no oil, no cooking.
  • In Pot Two, I sautéed the garlic and onion in oil first.

The results: No difference.

So nix the oil. Not one drop is needed. "Fat free" goodness doesn’t happen often so with each swallow, let’s just enjoy.

And feel mighty virtuous.

Hands-on time: 30 minutes
Time-to-table: 1-1/4 hours
Makes 13 cups
  • 3 15-ounce cans fat-free (about 5-1/2 cups) vegetable broth
  • 3 15-ounce cans diced or stewed tomatoes
  • 1 tablespoon minced garlic
  • 1 onion, chopped (about 1 cup)
  • 8 ounces fresh mushrooms, quartered (about 2 cups)
  • 3 zucchini, chopped (about 4 cups)
  • 2 carrots, chopped (about 1 cup)
  • 1 russet potato, skin on, chopped (about 1-3/4 cups)
  • 3 tablespoons chopped fresh parsley
  • 2 tablespoons chopped cilantro (optional)
  • 1 teaspoon dried basil
  • 1 teaspoon dried oregano
  • Salt and pepper to taste

Heat a four-quart Dutch oven or very large heavy pot on medium heat. Add the vegetable broth and tomatoes. Add all the remaining ingredients as they're prepped. Cover and bring to a boil. Reduce the heat to maintain a slow simmer and simmer until the vegetables are tender, about 30 minutes.

With a slotted spoon, transfer 3 cups of the cooked vegetables to a blender or food processor. Add about 1/4 cup cooking liquid to the blender and purée until smooth. Return the purée to the soup pot. Alternatively, use an immersion blender (affiliate link), just sticking it into the hot soup right in the pot and spritzing a few times, just enough to thicken the soup using the vegetables themselves, no flour, no added thickener.

Season to taste with salt and pepper and serve.

ALANNA's TIPS This recipe makes a bunch, so make sure your pot is big enough. I usually use two Dutch ovens, rather than dragging out the big stockpot. If you're reducing carbs as well as calories, substitute chopped turnips for the russet potato.
