Method
Preparation
- Heat 2 tablespoons olive oil in a 6-quart Dutch oven over medium heat until shimmering.
- Add the diced onion, carrots, and celery with a pinch of salt and sauté, stirring occasionally, until the onion is translucent and carrots begin to soften, 6–8 minutes.
- Add the minced garlic and cook 30–45 seconds until fragrant, taking care not to brown it.
Build the soup
- Stir in the canned diced tomatoes and tomato paste (if using), cook 1–2 minutes, scraping any browned bits from the bottom.
- Pour in 6 cups low-sodium stock and add the diced potatoes or butternut squash; bring to a gentle boil, then reduce to a low simmer.
- Simmer uncovered 18–22 minutes until the potatoes or squash are just tender.
Finish and serve
- Five to seven minutes before the end of simmering, add green beans, peas, and chopped spinach or kale; if adding small pasta, add it now and simmer until al dente (8–10 minutes).
- Season with 1 1/2 teaspoons kosher salt and 1/2 teaspoon black pepper, then taste and adjust seasoning.
- Turn off the heat and stir in 2 tablespoons chopped parsley and 1 tablespoon lemon juice; let the soup rest 5 minutes before serving.
Notes
Use low-sodium stock to control salt and add more after simmering. Add frozen vegetables in the last 5–7 minutes or briefly thaw and drain them first to avoid diluting the broth. For a creamier texture, purée a portion of the soup and stir it back in.
