Roasted Vegetable Soup: The Ultimate Guide & Recipe

Roasted vegetable soup: just the name conjures up images of warmth, comfort, and vibrant flavors dancing on your tongue. Have you ever craved a dish that’s both incredibly satisfying and packed with nutrients? This is it! Forget those bland, watery soups of your childhood; we’re talking about a deeply flavorful, intensely aromatic experience that will redefine your perception of vegetable soup.

While the concept of vegetable soup has existed for centuries across various cultures, the technique of roasting the vegetables before simmering them into a soup is a more modern innovation. It’s a game-changer! Roasting brings out the natural sweetness of the vegetables, caramelizing their edges and adding a depth of flavor that simply can’t be achieved through boiling alone. Think of it as unlocking the vegetables’ hidden potential.

People adore roasted vegetable soup for so many reasons. First, the taste is phenomenal. The roasting process concentrates the flavors, creating a rich, savory broth that’s incredibly satisfying. The texture is also a winner – you can choose to blend it until smooth and creamy, or leave it chunky for a heartier meal. And let’s not forget the convenience! It’s a fantastic way to use up leftover vegetables, and it’s a relatively hands-off recipe, perfect for busy weeknights. Plus, it’s a healthy and delicious way to load up on your daily dose of veggies. So, are you ready to discover the magic of roasted vegetable soup? Let’s get started!

Ingredients:

• 2 tablespoons olive oil, extra virgin
• 1 large yellow onion, chopped
• 2 carrots, peeled and chopped
• 2 celery stalks, chopped
• 4 cloves garlic, minced
• 1 red bell pepper, seeded and chopped
• 1 yellow bell pepper, seeded and chopped
• 1 large zucchini, chopped
• 1 large yellow squash, chopped
• 1 (28 ounce) can crushed tomatoes
• 6 cups vegetable broth, low sodium
• 1 teaspoon dried thyme
• 1 teaspoon dried oregano
• 1/2 teaspoon red pepper flakes (optional)
• Salt and freshly ground black pepper to taste
• 1/4 cup chopped fresh basil, for garnish
• 1/4 cup grated Parmesan cheese, for garnish (optional)
• Crusty bread, for serving (optional)

Preparing the Vegetables:

Okay, let’s get started! The key to a truly amazing roasted vegetable soup is, well, roasting the vegetables! This brings out their natural sweetness and adds a depth of flavor that you just can’t get any other way. Trust me, it’s worth the extra step.

1. Preheat your oven to 400°F (200°C). Make sure your oven is fully preheated before you start roasting. This ensures even cooking and prevents the vegetables from steaming instead of roasting.
2. Prepare the vegetables. Wash and chop all the vegetables according to the ingredient list. Aim for roughly the same size pieces so they cook evenly. I like to chop the onion, carrots, and celery into about 1/2-inch pieces. The bell peppers, zucchini, and yellow squash can be slightly larger, around 1-inch pieces.
3. Toss with olive oil and seasonings. In a large bowl, combine the chopped onion, carrots, celery, red bell pepper, yellow bell pepper, zucchini, and yellow squash. Drizzle with 2 tablespoons of olive oil. Add the minced garlic, dried thyme, dried oregano, and red pepper flakes (if using). Season generously with salt and freshly ground black pepper. Toss everything together until the vegetables are evenly coated with the oil and seasonings.
4. Roast the vegetables. Spread the seasoned vegetables in a single layer on a large baking sheet. If you have too many vegetables to fit comfortably on one sheet, use two baking sheets to avoid overcrowding. Overcrowding will cause the vegetables to steam instead of roast. Roast in the preheated oven for 30-40 minutes, or until the vegetables are tender and slightly caramelized. Stir the vegetables halfway through the roasting time to ensure even cooking. You’re looking for a nice golden-brown color and slightly softened texture.

Making the Soup:

Now that the vegetables are beautifully roasted, it’s time to turn them into a delicious and comforting soup! This part is relatively quick and easy.

1. Sauté the roasted vegetables (optional, but recommended). While not strictly necessary, I find that briefly sautéing the roasted vegetables in a pot before adding the broth enhances the flavor even further. In a large pot or Dutch oven, heat 1 tablespoon of olive oil over medium heat. Add the roasted vegetables and sauté for 5-7 minutes, stirring occasionally, until they are slightly softened and fragrant. This step helps to meld the flavors together and create a richer, more complex soup.
2. Add the crushed tomatoes and vegetable broth. Pour in the crushed tomatoes and vegetable broth. Stir well to combine. Bring the mixture to a simmer over medium heat.
3. Simmer the soup. Reduce the heat to low, cover the pot, and simmer for at least 15 minutes, or up to 30 minutes. The longer the soup simmers, the more the flavors will meld together. This is a great time to relax and let the soup do its thing.
4. Blend the soup. This is where the magic happens! You have a couple of options for blending the soup. You can use an immersion blender to blend the soup directly in the pot. This is the easiest and least messy option. Alternatively, you can carefully transfer the soup in batches to a regular blender. Be very careful when blending hot liquids! To prevent splattering, remove the center piece of the blender lid and cover the opening with a clean kitchen towel. Blend until the soup is smooth and creamy.
5. Season to taste. After blending, taste the soup and adjust the seasoning as needed. You may need to add more salt, pepper, or even a pinch of red pepper flakes to achieve your desired flavor.

Serving the Soup:

The final step is the best part: enjoying your homemade roasted vegetable soup! There are so many ways to customize this soup and make it your own.

1. Garnish and serve. Ladle the soup into bowls and garnish with chopped fresh basil and grated Parmesan cheese (if using). A swirl of cream or a dollop of sour cream would also be delicious.
2. Serve with crusty bread. I highly recommend serving the soup with a side of crusty bread for dipping. The bread is perfect for soaking up all the delicious broth.
3. Optional additions. Feel free to add other toppings to your soup, such as croutons, toasted pumpkin seeds, or a drizzle of olive oil. You can also add cooked pasta or rice to make the soup more substantial.

Tips and Variations:

• Customize the vegetables. Don’t be afraid to experiment with different vegetables! Other great options include sweet potatoes, butternut squash, Brussels sprouts, and cauliflower.
• Add protein. For a heartier soup, add cooked chicken, sausage, or beans.
• Make it vegan. To make the soup vegan, simply omit the Parmesan cheese garnish.
• Store leftovers. Leftover soup can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave.
• Freeze for later. Roasted vegetable soup freezes well, making it a great option for meal prepping. Allow the soup to cool completely before transferring it to freezer-safe containers. Freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
