How to Make Healthy Tomato Zucchini Soup

Let me show you how easy it is to make this Healthy Tomato Zucchini Soup:

Sauté Vegetables and Aromatics

1. First, I heat the canola oil in a large pot or Dutch oven over medium heat.
2. I add the minced onions and sauté until they become translucent, which takes about 1 minute.
3. Next, I add the diced zucchini, mix it well, and sauté for another minute.
4. I add the minced garlic, Italian seasoning, black pepper, and red chili pepper flakes. I continue cooking, stirring constantly, for 1 more minute until the garlic is fragrant.

Simmer the Soup

1. I stir in the tomato sauce (I used marinara for extra flavor, as suggested) and the minced fresh basil. I give it a quick stir and let it cook for about 1 minute to lightly caramelize the tomato sauce.
2. Then, I add the vegetable stock and bring the mixture to a simmer.
3. I lower the heat to medium-low, cover the pot, and let the soup cook for about 10 minutes, stirring once in a while, until the zucchini is very tender.

Blend and Serve

1. I take the pot off the heat. Carefully, using an immersion blender right in the pot, or by transferring in batches to a stand blender, I pulse the Tomato Zucchini Soup until it reaches a smooth consistency.
2. I taste the soup and adjust the seasoning with salt if needed.
3. I divide the soup into bowls.
4. Garnish and serve

Tips and Tricks for the BEST Tomato Zucchini Soup

Here are my secrets for making this healthy soup truly exceptional:

• Sauté Aromatics: Taking the time to sauté the onion and garlic builds a flavorful foundation.
• Caramelize Tomato Sauce: Cooking the tomato sauce briefly before adding the broth deepens its flavor.
• Use an Immersion Blender: An immersion blender makes pureeing the soup directly in the pot super easy and minimizes cleanup. If using a regular blender, be very careful when blending hot liquids!
• Don't Overcook Zucchini: Cook just until tender before blending for the freshest flavor.
• Adjust Consistency: If the soup is too thick after blending, stir in a little more vegetable broth or water until it reaches your desired consistency.

How to Serve

This Healthy Tomato Zucchini Soup is delicious served hot! Enjoy it:

• Garnished: Top with some reserved diced zucchini (for texture!), more fresh basil or parsley, croutons (use gluten-free if needed), and a drizzle of good quality olive oil.
• With Bread: Serve with crusty bread (gluten-free if needed) for dipping.
• With Grilled Cheese: A classic pairing for tomato soup! Use gluten-free bread and vegan cheese if needed.
• As a Starter: A light and healthy start to a larger meal.

Make Ahead and Storage

This soup is great for making ahead! Store leftover Tomato Zucchini Soup in an airtight container in the refrigerator for up to 4-5 days. Reheat gently on the stovetop or in the microwave. This soup also freezes well for up to 3 months. Thaw overnight in the refrigerator before reheating.

FAQs about Healthy Tomato Zucchini Soup

• Can I use fresh tomatoes instead of canned tomato sauce?
  • Yes, you could use about 1.5 cups of fresh, chopped, ripe tomatoes (like Roma). You might need to simmer the soup a bit longer to allow them to break down before blending.
• Can I add other vegetables?
  • Absolutely! Carrots, celery, bell peppers, or even potatoes could be added during the initial sauté step (adjust simmering time accordingly).
• Is this soup spicy?
  • The red pepper flakes add a mild warmth. Adjust the amount or omit them based on your preference for this Tomato Zucchini Soup.
