Simply Tomato Soup
Ingredients
- 4 ears of corn, husked
- 1 quart low-sodium chicken broth, vegetable broth, or water, plus more as needed
- Kosher salt
- 4 tablespoons olive oil or butter
- 1 to 2 cups cubed zucchini or summer squash
- ½ cup chopped onion
- ¼ cup chopped scallions
- ½ cup chopped celery
- 1 garlic clove, finely chopped (plus more, to taste)
- Freshly ground black pepper
- 1 to 2 cups cubed, peeled Yukon gold or red-skinned potatoes
- 1 to 2 cups cubed tomatoes
- About ½ cup finely sliced fresh basil leaves
Instructions
- Cut the kernels off the corncobs and set the kernels aside. Place the reserved cobs in a pot with 1 quart of the broth or water, along with a teaspoon of salt. Bring the pot to a simmer over medium heat and cook until reduced to about 6 cups, about 45 minutes.
- While the broth simmers, heat 2 tablespoons of the olive oil or butter in a medium skillet over medium heat. Add the zucchini or squash in a single layer, season with a pinch of salt, and let cook, undisturbed, for about a minute, until lightly browned; flip and cook the other side until browned and slightly tender but not mushy. Set aside.
- In a large soup pot or Dutch oven, heat the remaining oil or butter over medium heat. Add the onions, scallions, celery, and garlic. Season lightly with salt and pepper.
- When the corn broth is ready, strain it and measure to see if you have 6 cups; if not, add more broth or water, then add to the soup pot, along with the potatoes and 2 teaspoons of salt. Bring to a simmer and cook until the potatoes are tender, but not mushy, 15 to 20 minutes.
- Add the tomatoes, sautéed zucchini, and reserved corn kernels and simmer until all the vegetables are heated through. Taste and adjust seasoning as desired.
- To serve, divide the basil among soup bowls and ladle the hot soup on top.
