Our Delicious Smoky Tomato-Red Onion Soup Recipe Is Packed With Health Benefits

A dollop of sour cream on top takes this richly flavorful bowl from good to great!

Tomato soup is a classic comfort dish – especially when it’s paired with a gooey grilled cheese sandwich. And this soup is good for you, too: tomatoes are loaded with vitamin C! At the Woman’s World test kitchen, we made this yummy bowl even better by adding red onion, which is high in quercetin, an antioxidant that improves cellular function. Not only will this smoky tomato-red onion soup recipe deliver health benefits, it will also delight your tastebuds. The soup is extra rich in flavor, thanks to garlic, beef broth and a little brown sugar. 

Quick tip: When you’re done chopping onions for this soup, save the skins! They have 53 percent more quercetin than the onions themselves. To reap the benefits, make onion skin tea by rinsing the skins thoroughly and simmering in a pot of water for up to 30 minutes. Strain into a mug and sip throughout the day.
