· 1 cup water
· 2 bay leaves
· 1 teaspoon kosher salt
· ½ teaspoon black pepper
· 2 Yukon Gold potatoes, cut into ½-inch cubes
· 1 cup fresh or frozen green beans, trimmed and cut into 1-inch pieces
· 1 cup frozen corn

For the Homemade Croutons:
· 3 cups cubed day-old bread (baguette, sourdough, or Italian bread)
· 3 tablespoons olive oil or melted butter
· 2 cloves garlic, minced
· ½ teaspoon kosher salt
· ¼ teaspoon black pepper
· 2 tablespoons fresh parsley, chopped (optional)
Optional Garnish:

· Fresh parsley or basil
Step-by-Step Instructions
Step 1: Make the Croutons
Preheat your oven to 375°F (190°C). In a large bowl, toss the bread cubes with olive oil, minced garlic, salt, and pepper until evenly coated. Spread the bread cubes in a single layer on a baking sheet. Bake for 10-15 minutes, tossing halfway through, until golden brown and crispy. If using fresh parsley, toss it in during the last 2 minutes of baking. Set aside.
Step 2: Sauté the Aromatics
Heat the olive oil in a large Dutch oven or heavy-bottomed pot over medium heat. Add the diced onion, carrots, and celery. Cook for 8-10 minutes, stirring occasionally, until the vegetables are softened and the onion is translucent.
Step 3: Add the Garlic and Spices
Add the minced garlic, oregano, thyme, and smoked paprika (if using). Cook for 60 seconds until fragrant.
Step 4: Build the Broth
Pour in the crushed tomatoes, vegetable broth, and water. Add the bay leaves, salt, and pepper. Stir to combine.
Step 5: Add the Potatoes and Green Beans
Add the diced potatoes and green beans to the pot. Bring the soup to a boil, then reduce the heat to low. Cover and simmer for 15-20 minutes, until the potatoes are fork-tender.
Step 6: Add the Corn and Finish
Stir in the frozen corn and simmer for another 5 minutes until heated through. Remove the bay leaves. Stir in the red wine vinegar or lemon juice. Taste and adjust salt and pepper.
Step 7: Serve
Ladle the soup into bowls. Top with a generous handful of homemade croutons. Sprinkle with Parmesan cheese and fresh parsley if desired.
Cooking Tips and Pro Tips for Best Results
· Cut vegetables into uniform pieces: Evenly sized vegetables cook at the same rate. Aim for ½-inch dice for the potatoes, carrots, and celery.
· Use day-old bread for croutons: Slightly stale bread absorbs the oil and garlic better and becomes crispier. Fresh bread works too, but may need an extra 2-3 minutes in the oven.
· Do not overcook the vegetables: The potatoes should be fork-tender, not falling apart. The green beans should be tender-crisp.
· Add vinegar at the end: A splash of red wine vinegar or lemon juice brightens the soup and balances the acidity of the tomatoes. Do not skip this step.
· Make it a heartier meal: Add 1 can of drained and rinsed cannellini beans or chickpeas. Add 1 cup of cooked lentils or barley.

Frequently Asked Questions (FAQ)
1. Can I use fresh tomatoes instead of canned?
Yes. Use 2 lbs of ripe Roma tomatoes, chopped. You may need to add an extra 1 cup of broth, as fresh tomatoes are less concentrated than canned.
2. Can I add meat to this soup?
Absolutely. Brown ½ lb of Italian sausage, ground beef, or diced chicken before sautéing the vegetables. Add cooked shredded chicken or turkey at the end.
3. How do I keep my croutons crispy?
Store croutons in an airtight container at room temperature. Do not refrigerate them. Add them to the soup just before serving; if they sit in the soup too long, they will become soggy.
4. Can I make this soup in a slow cooker?
Yes. Sauté the aromatics on the stovetop first (this step is important for flavor). Transfer to a slow cooker. Add the remaining ingredients (except the corn and vinegar). Cook on low for 6-7 hours or on high for 3-4 hours. Stir in the corn and vinegar during the last 30 minutes.
5. What can I use instead of vegetable broth?
Use chicken broth for a non-vegetarian version. Use water with 1 tablespoon of vegetable bouillon paste (like Better Than Bouillon). This adds even more flavor.
6. Can I freeze this soup with the potatoes?
Yes. Potatoes can become slightly softer when frozen and thawed, but they are still delicious. If you prefer a firmer texture, add the potatoes after thawing and simmer until tender.
