Roasted Vegetable Soup

Roasted Vegetable Soup is a rich and hearty dish that elevates the classic vegetable soup with deep, smoky flavors.

This simple yet satisfying soup is perfect for a cozy weeknight meal, and the best part? It’s easy to make and can be customized to your taste.

Why Roasting Vegetables Makes the Best Soup

When it comes to making vegetable soup, roasting the veggies before adding them to the soup pot is a game-changer. Here’s why:

Deepened Flavors: Roasting vegetables brings out their natural sweetness and creates a caramelized exterior that adds a savory, smoky depth to the soup.
Less Water: Vegetables release moisture when they are roasted, which helps intensify their flavor. This is especially important for soups, as it reduces the need for additional seasonings.
Perfect Texture: Roasted vegetables add a pleasing texture to the soup. The caramelization process adds a lovely, slightly crispy bite in contrast to the smoothness of the soup.

By choosing to roast the vegetables instead of boiling them, you end up with a more flavorful, aromatic, and satisfying soup.

What Are the Best Vegetables for Roasted Vegetable Soup?

When it comes to making the best roasted vegetable soup, choosing the right vegetables is key. Certain vegetables roast beautifully and blend seamlessly into the soup to create a rich, creamy texture. Here are the vegetables you’ll need:

Sweet Potato: This vegetable adds natural sweetness and a creamy texture to the soup. Sweet potatoes are also rich in vitamin A and fiber.
Red Bell Peppers: Roasted peppers bring a smoky, slightly sweet flavor to the soup. They’re packed with vitamin C and antioxidants.
Parsnips: These root vegetables add a slightly nutty, earthy flavor. They pair well with sweet potatoes and carrots, adding variety to the taste profile.
Carrots: Carrots bring a subtle sweetness and vibrant color to the soup. They’re a great source of vitamin A and beta-carotene.
Onions: Roasting onions brings out their natural sugars, making them sweet and soft. They also help to form the base of the soup’s flavor.
Garlic: Roasting garlic adds a sweet, mellow depth to the soup, without the sharpness of raw garlic. Plus, garlic is a great source of vitamins and minerals.

The Role of Spices in Roasted Vegetable Soup

While the vegetables provide the bulk of the flavor in this soup, spices are key to enhancing and deepening the taste. Here’s what you’ll need:

Cumin: Adds a warm, earthy flavor that works well with roasted vegetables, especially root vegetables like carrots and sweet potatoes.
Ground Coriander: Brings a citrusy, slightly sweet flavor that pairs beautifully with cumin and enhances the earthiness of the roasted vegetables.
Turmeric: Known for its bright yellow color and earthy flavor, turmeric brings warmth and a subtle bitterness that balances the sweetness of the vegetables.
Salt and Pepper: These simple seasonings help to elevate the natural flavors of the vegetables and bring the soup together.
Optional Spices: For added depth, you can also include paprika or a pinch of cayenne pepper to introduce a bit of heat.

How to Make Roasted Vegetable Soup

Making this roasted vegetable soup is simple and straightforward. Here’s the step-by-step process:

Step 1: Preheat the Oven and Prepare the Vegetables

Preheat your oven to 200°C (390°F).
Peel and dice the sweet potato, carrots, and parsnips into small chunks (around ¾ inch). This ensures that they cook evenly.
Slice the red bell peppers into large pieces and quarter the onions. Keep the garlic cloves whole, with their skins intact, to prevent burning.

Step 2: Season and Roast the Vegetables

In a large mixing bowl, toss the diced vegetables with olive oil, salt, cumin, ground coriander, turmeric, and black pepper.
Spread the seasoned vegetables on a large baking tray in a single layer to ensure even roasting.
Roast for 25-30 minutes, flipping the vegetables halfway through to ensure they cook evenly and get that beautiful caramelized color.
After 15 minutes, check for any vegetables that might be charring too fast and adjust their placement on the tray.

Step 3: Combine Vegetables with Stock

Once the vegetables are roasted and tender, remove them from the oven and transfer them to a large soup pot.
Add 5 cups of vegetable stock (or enough to just cover the vegetables). Bring the mixture to a boil, then lower the heat and simmer for 15 minutes to ensure all the flavors meld together.

Step 4: Blend the Soup

Remove the pot from the heat and use an immersion blender to blend the soup until smooth and creamy. If you don’t have an immersion blender, you can carefully transfer the soup in batches to a regular blender.
Gradually add more stock to achieve your desired consistency.

Step 5: Final Adjustments

Taste the soup and adjust the seasoning as necessary, adding more salt, pepper, or a pinch of red pepper flakes for extra heat.
Garnish the soup with fresh thyme or a drizzle of extra virgin olive oil for an added touch of flavor.

Tips for Perfect Roasted Vegetable Soup

While the recipe for Roasted Vegetable Soup is fairly straightforward, there are some important tips to ensure that your soup turns out perfectly every time. Follow these tips for the best results.

Pre-Roasting Vegetables: Get the Right Texture

When roasting vegetables, it’s crucial to ensure they cook evenly and get that delicious caramelized texture. Here’s how to achieve the perfect roast:

Uniform Size: Dice your root vegetables (like sweet potatoes, parsnips, and carrots) into small, even-sized pieces. This helps them cook at the same rate.
Don’t Overcrowd the Pan: Spread the vegetables out on a baking tray, ensuring they’re not stacked on top of each other. This allows each piece to roast evenly and get a beautiful char.
Flip Halfway: Halfway through the roasting process, give the vegetables a quick flip. This ensures all sides of the vegetables get that beautiful caramelized color.

Enhancing the Flavor with Stock and Herbs

The vegetable stock you use will have a significant impact on the soup’s flavor. Here are some tips for maximizing flavor:

Choose Low-Sodium Stock: If you’re looking to control the sodium content, opt for low-sodium vegetable stock. You can always add salt to taste later.
Herb Infusion: To take your soup to the next level, try adding fresh herbs like thyme, rosemary, or bay leaves while simmering the vegetables in the stock. These herbs infuse the broth with extra flavor.
Scrape the Roasting Tray: After roasting, there will be caramelized bits stuck to the bottom of your baking tray. Don’t throw that flavor away! Simply add a splash of boiling water to the tray and scrape up all those delicious, browned bits. Pour that into the soup pot for a deeper flavor profile.

Consistency and Texture

One of the best features of Roasted Vegetable Soup is its creamy, smooth texture. Here are some tips for achieving the perfect consistency:

Use an Immersion Blender: If you have an immersion blender, it’s the easiest and most efficient tool for pureeing the soup directly in the pot.
Adjust Consistency: After blending, if the soup is too thick, simply add more vegetable stock until it reaches your desired consistency. If it’s too thin, let the soup simmer uncovered for a few more minutes to reduce and thicken.
Chunky or Smooth: For a chunkier texture, blend only part of the soup and leave some vegetables intact. This gives the soup a rustic feel while maintaining a creamy base.

Make-Ahead and Storage

This soup is ideal for making in advance. Here’s how to store it for later:

Refrigerate: Once the soup has cooled, transfer it to an airtight container and store it in the fridge for up to 5 days.
Freeze for Later: This soup freezes beautifully. After cooling, divide the soup into freezer-safe containers. Label with the date, and store in the freezer for up to 3 months. When you’re ready to eat it, simply thaw it in the fridge overnight or reheat directly from frozen.
Reheat: To reheat, warm it on the stovetop over medium heat, adding more stock if needed to loosen the consistency.

Serving Suggestions

This Roasted Vegetable Soup is a versatile dish that pairs beautifully with many sides. Here are some great serving ideas:

Bread: A slice of crusty bread, such as French bread or sourdough, is perfect for dipping in this flavorful soup.
