Ingredients
- 1 medium yellow onion, finely chopped
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 tablespoons brown sugar
- 2 tablespoons tomato paste
- 1/2 teaspoon table salt
- 1 teaspoon freshly ground black pepper
- Pinch of cayenne pepper

- 4 cups low-sodium chicken or vegetable broth, plus more as needed
- 2 bay leaves
- 3/4 cup heavy cream
- 1 tablespoon dry sherry
Tips Before You Begin
For added texture, consider adding croutons on top before serving. If you’re using table salt instead of kosher salt, remember to halve the measurements. Using undrained diced tomatoes ensures maximum flavor.
Prepare the Soup Base
In a microwave-safe bowl, mix together 1 medium yellow onion (finely chopped), 3 tablespoons unsalted butter, 3 tablespoons all-purpose flour, 2 tablespoons brown sugar, 2 tablespoons tomato paste, 1/2 teaspoon table salt, 1 teaspoon freshly ground black pepper, and a pinch of cayenne pepper.
Microwave on high, stirring occasionally, until the onion softens, about 5 minutes. Transfer this mixture to a slow cooker.
Build the Soup
Add 3 (14.5-ounce) cans undrained diced tomatoes, 4 cups low-sodium chicken or vegetable broth, and 2 bay leaves to the slow cooker.
Cover and cook on low for 4 to 6 hours or on high for 3 to 5 hours, until flavors meld and vegetables are tender.
Blend and Finish
Remove and discard the bay leaves. Working in batches, blend the soup until smooth, about 1 to 2 minutes per batch, and then return it to the slow cooker. Stir in 3/4 cup heavy cream and 1 tablespoon dry sherry.
If the soup is too thick, thin it with additional hot broth. Season with salt and freshly ground black pepper to taste.
Serve warm.
