Classic Tomato Soup

Ingredients

2 (28-ounce) cans diced tomatoes ¾ cup low-sodium chicken broth 3 tablespoons unsalted butter 1 onion, chopped 1 bay leaf 1 teaspoon brown sugar 2 tablespoons tomato paste 2 tablespoons all-purpose flour ½ teaspoon baking soda ½ teaspoon table salt ½ cup heavy cream

Before You Begin

Use unseasoned canned tomatoes.

Instructions

  1. Drain tomatoes in colander set over large bowl, pressing lightly to release juices. Transfer tomato juice and chicken broth to large measuring cup (mixture should measure about 4 cups); reserve.
  2. Melt butter in Dutch oven over medium heat. Add onion and cook until softened, about 5 minutes. Add two-thirds of drained tomatoes, bay leaf, and brown sugar and cook, stirring occasionally, until tomatoes begin to brown, about 15 minutes.
  3. Add tomato paste and flour to pot and cook, stirring frequently, until paste begins to darken, 1 to 2 minutes. Slowly stir in reserved tomato juice–broth mixture, remaining tomatoes, baking soda, and salt and bring to boil. Reduce heat to medium-low and simmer until slightly thickened, about 5 minutes.

Why This Recipe Works

Because tomato season is fleeting, we opted for canned tomatoes instead of fresh in our Classic Tomato Soup. Draining the tomatoes and browning them in a Dutch oven helped concentrate their flavor, while setting aside some and adding them at the end of cooking preserved their natural freshness.

When it came time to season our Classic Tomato Soup, we found that a light hand was best. After trying everything from Parmesan to anchovies, we settled on a single bay leaf and a bit of chicken broth to add a meaty backdrop. Our final recipe had a harsh, almost metallic taste until we added a bit of baking soda, which helped neutralize the acidity of the tomatoes.
