Ingredients
Method
Step 1: Start the Base
- In a large pot over medium heat, add the olive oil and butter. Let the butter melt completely.
- Stir in the dried basil, dried thyme, and crushed red pepper flakes (if using). Cook for about 30 seconds, stirring frequently, until the herbs are fragrant.
- Add the finely chopped onion, grated garlic, and 2 teaspoons of kosher salt. Cook, stirring occasionally, until the onions are softened and lightly golden, about 6 minutes.
Step 2: Build the Soup
- Stir in the halved grape tomatoes and 2 tablespoons of vegetable bouillon paste. Cook for 2–3 minutes, gently mashing the tomatoes to release their juices.
- Add the carrots, celery, potatoes, and fennel to the pot. Season with the remaining 1 teaspoon of kosher salt and stir everything together.
Step 3: Add the Broth
- Add the Parmesan rind and sliced garlic to the pot. Pour in 8 cups of water and stir to combine.
- Bring the soup to a gentle simmer, then reduce the heat to medium-low. Cover the pot partially and cook for 20–25 minutes, stirring occasionally, until the vegetables are tender.
Step 4: Add Frozen Vegetables
- Remove and discard the Parmesan rind from the soup.
- Stir in the frozen corn, green beans, and peas. Let the soup cook for an additional 2–3 minutes, or until the frozen vegetables are thawed and heated through.
Step 5: Garnish and Serve
- Stir in the chopped parsley just before serving for a pop of freshness.
- Ladle the soup into bowls and enjoy it warm. Pair with crusty bread or crackers for a complete meal.
Notes
- Customizable Veggies: Feel free to swap or add vegetables based on what you have on hand. Zucchini, bell peppers, or mushrooms would be great additions.
- Boost the Flavor: For extra flavor, substitute some or all of the water with vegetable or chicken broth.
- Storage Tips: Store leftovers in an airtight container in the refrigerator for up to 3 days. The flavors deepen as it sits, making it even tastier the next day!
- Freezer-Friendly: Freeze the soup in individual portions for up to 3 months. Thaw and reheat on the stovetop for a quick and easy meal.
- Vegan Option: To make this soup vegan, use plant-based butter or extra olive oil and omit the Parmesan rind.
