Ingredients

This recipe relies on the inherent sweetness of its star players, amplified by the magic of roasting.

• 1 lb carrots, peeled and cut into 1/2-inch rounds
• 1/2 lb parsnips, peeled and cut into 1/2-inch rounds
• 1 large yellow onion, quartered
• 5 tablespoons olive oil, divided
• 1 1/2 teaspoons kosher salt, divided
• 1/4 teaspoon black pepper, divided
• 1/2 baguette, cut into 16 thin slices
• 3 cups water, approximate (plus more as needed)

Equipment Needed

To bring this delightful soup to life, you’ll need a few essential kitchen tools:

• Large roasting pan
• Baking sheet
• Blender (high-powered blender recommended for the smoothest texture)
• Medium saucepan

Instructions

The beauty of this soup lies in its simplicity, with the oven doing most of the heavy lifting.

1. Preheat your oven to a welcoming 400 degrees Fahrenheit (200 degrees Celsius). This is the perfect temperature to coax out the natural sugars from the root vegetables, creating those delightful caramelized edges.

2. In a large roasting pan, combine the prepared carrots, parsnips, and quartered yellow onion. Drizzle them with 3 tablespoons of olive oil, and season generously with 1 teaspoon of the kosher salt and 1/4 teaspoon of the black pepper. Toss everything together until the vegetables are evenly coated. Spread the vegetables in an even layer across the roasting pan, ensuring they aren’t too crowded, which would steam them rather than roast.

3. Roast the vegetables, stirring occasionally, for approximately 45 minutes, or until they are tender and beautifully golden brown. The edges might even develop a lovely, slightly crisped texture, which adds another layer of flavor.

4. While the vegetables are roasting, prepare the accompanying toast. Arrange the baguette slices on a baking sheet. Brush them with the remaining 2 tablespoons of olive oil.

5. During the last 10 minutes of the vegetables’ roasting time, place the baking sheet with the bread into the oven. Toast the baguette slices until they are crisp and golden. These will serve as a delightful crunchy garnish for your soup.

6. Once the vegetables are perfectly roasted, carefully transfer them to a blender. Add 3 cups of water to the blender.

7. Puree the mixture until it is wonderfully smooth and velvety. If the soup is too thick for your liking, you can add more water, 1/4 cup at a time, until you achieve your desired consistency. You might also want to taste and add the remaining 1/2 teaspoon of kosher salt and 1/4 teaspoon of black pepper at this stage, adjusting to your preference.

8. Transfer the pureed soup to a medium saucepan. Rewarm the soup over medium-low heat, stirring occasionally, until it is heated through. Be careful not to let it boil vigorously.

9. To serve, divide the warm soup among individual bowls. Garnish each bowl with the crisp olive oil toast you prepared earlier.

Expert Tips & Tricks

• Uniformity is Key: When cutting your carrots and parsnips, aim for consistent 1/2-inch rounds. This ensures they cook evenly in the roasting pan, preventing some pieces from becoming mushy while others remain undercooked.
• Don’t Crowd the Pan: Giving your vegetables ample space in the roasting pan is crucial for achieving that desirable caramelization. If they are too crowded, they will steam instead of roast, leading to a less intense flavor.
• The Power of the Parsnip: Parsnips can sometimes have a slightly woody core. If you notice this in larger parsnips, you can carefully cut it out before chopping them into rounds.
• Blender Brilliance: For an exceptionally silky smooth soup, a high-powered blender is your best friend. If you don’t have one, you may need to blend in batches and ensure you process each batch thoroughly. For an even smoother finish, you can pass the soup through a fine-mesh sieve after blending.
• Make-Ahead Magic: This soup is a fantastic candidate for making ahead. Once cooled, store it in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop, adding a splash more water if needed to achieve the right consistency.

Serving & Storage Suggestions

This Roasted Carrot and Parsnip Soup is best served piping hot, immediately after reheating. The crisp baguette slices offer a wonderful textural contrast to the velvety soup. For an extra touch of elegance, consider a drizzle of good quality olive oil or a scattering of fresh herbs like chives or parsley.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low heat, stirring frequently. You may need to add a little extra water or vegetable broth to thin it out to your desired consistency. This soup is not ideal for freezing, as the texture can be compromised upon thawing.

Variations & Substitutions

While this recipe is wonderfully satisfying as is, feel free to explore these delicious variations:

• Spice it Up: For a gentle warmth, add a pinch of cayenne pepper or a finely minced fresh chili to the vegetables before roasting.
• Creamy Dream: If you aren’t adhering to a vegan diet, a swirl of heavy cream or a dollop of crème fraîche at the end of cooking adds a luxurious richness. For a dairy-free creamy alternative, consider adding a splash of full-fat coconut milk.
• Herbaceous Notes: Infuse the soup with additional herbal notes by adding a sprig of fresh thyme or rosemary to the roasting pan with the vegetables. Remove before blending.
• Root Vegetable Medley: Feel free to substitute some of the carrots or parsnips with other hearty root vegetables like sweet potatoes or celery root. Adjust roasting times accordingly.

FAQs (Frequently Asked Questions)

Q: Why do I need to roast the vegetables first?
A: Roasting caramelizes the natural sugars in the carrots and parsnips, deepening their flavor and adding a subtle sweetness and complexity that simply boiling them wouldn’t achieve.

Q: Can I use a different type of onion?
A: Absolutely. A sweet onion or even a red onion would work well, offering slightly different flavor profiles.

Q: What if I don’t have a high-powered blender?
A: You can use a regular blender or an immersion blender. You may need to blend in batches and process for a bit longer to achieve a smooth texture. Sieving the soup afterwards is also a good option for extra smoothness.

Q: Can I make this soup ahead of time?
A: Yes, this soup is an excellent candidate for meal prep. It can be made and stored in the refrigerator for up to 3 days and reheats beautifully.

Q: What can I use instead of baguette for the toast?
A: Any crusty bread will work. Sourdough, ciabatta, or even whole wheat slices would be delicious, brushed with olive oil and toasted until crisp.
