Why Roast the Vegetables?
Roasting vegetables is a game-changer for soup. Here’s why:
* **Enhanced Flavor:** Roasting caramelizes the natural sugars in the vegetables, creating a deeper, sweeter, and more complex flavor profile.
* **Concentrated Flavors:** As the vegetables roast, they lose some of their moisture, which intensifies their natural flavors.
* **Improved Texture:** Roasting softens the vegetables while also adding a slight char or crispness around the edges, providing a more interesting texture.
* **Aromatic Delight:** The aroma of roasting vegetables is incredibly inviting and adds to the overall sensory experience of the soup.
Ingredients You’ll Need
* **Vegetables:**
* 1 large onion, chopped
* 2 carrots, chopped
* 2 celery stalks, chopped
* 1 butternut squash (about 2 pounds), peeled, seeded, and cubed
* 2 bell peppers (any color), chopped
* 4 cloves garlic, minced
* Optional: Other vegetables like sweet potatoes, parsnips, broccoli florets, Brussels sprouts, or cauliflower florets can be added or substituted.
* **Kale:**
* 1 bunch kale, stemmed and chopped (about 6 cups packed). Tuscan (lacinato) or curly kale works well.

Step-by-Step Instructions
Follow these detailed steps to create your own flavorful Roasted Vegetable and Kale Soup:
**1. Prepare the Vegetables for Roasting:**
* Preheat your oven to 400°F (200°C). Line two large baking sheets with parchment paper. This makes for easy cleanup.
* Wash and chop all the vegetables: onion, carrots, celery, butternut squash, bell peppers. Mince the garlic.
* In a large bowl, toss the chopped vegetables with 2-3 tablespoons of olive oil, dried thyme, dried rosemary, red pepper flakes (if using), salt, and pepper. Make sure the vegetables are evenly coated with oil and seasonings.
**2. Roast the Vegetables:**
* Spread the seasoned vegetables in a single layer on the prepared baking sheets. Avoid overcrowding the pans, as this will steam the vegetables instead of roasting them. If necessary, use two baking sheets.
* Roast for 30-40 minutes, or until the vegetables are tender and slightly caramelized. Stir the vegetables halfway through roasting to ensure even cooking.
**3. Sauté Aromatics (if desired):**
* While the vegetables are roasting, you can begin building the flavor base for your soup. In a large soup pot or Dutch oven, heat a tablespoon of olive oil over medium heat. Add the chopped onion (if not already roasted) and sauté until softened, about 5-7 minutes. Add the minced garlic (if not already roasted) and cook for another minute until fragrant. This step is optional; you can add the roasted onions and garlic directly to the pot with the broth.
**4. Combine Roasted Vegetables and Broth:**
* Once the vegetables are roasted, transfer them to the soup pot or Dutch oven. Add the vegetable broth (or chicken broth) to the pot. If using a Parmesan rind, add it to the pot at this stage.
* Bring the soup to a simmer over medium heat.
**5. Simmer and Develop Flavor:**
* Reduce the heat to low, cover the pot, and simmer for at least 15-20 minutes to allow the flavors to meld together. The longer it simmers, the richer the flavor will become. You can simmer it for up to an hour or more.
**6. Add Kale:**
* Stir in the chopped kale. Cook until the kale is wilted and tender, about 5-7 minutes.
**7. Add Optional Ingredients:**
* If using diced tomatoes, lentils, or beans, stir them into the soup during the last 5-10 minutes of cooking. This will allow them to heat through without becoming mushy.
**8. Season to Taste:**
* Taste the soup and adjust the seasoning as needed. Add more salt, pepper, thyme, rosemary, or red pepper flakes to your liking. A squeeze of fresh lemon juice can also brighten the flavors.
**9. Remove Parmesan Rind (if used):**
* If you added a Parmesan rind to the broth, remove it before serving.
**10. Serve and Enjoy:**
* Ladle the Roasted Vegetable and Kale Soup into bowls. Garnish with fresh parsley or other herbs, if desired. Serve hot with crusty bread, a dollop of yogurt, or a sprinkle of Parmesan cheese.
Tips for Success
* **Don’t Overcrowd the Baking Sheet:** Ensure the vegetables are spread in a single layer when roasting. Overcrowding will steam the vegetables instead of roasting them.
* **Use High-Quality Olive Oil:** The flavor of the olive oil will impact the overall taste of the soup, so use a good-quality extra virgin olive oil.
* **Customize Your Vegetables:** Feel free to substitute or add other vegetables based on your preferences and what you have on hand. Sweet potatoes, parsnips, broccoli, and cauliflower are all excellent additions.
* **Adjust the Seasoning:** Taste the soup frequently and adjust the seasoning as needed. Don’t be afraid to experiment with different herbs and spices.
* **Make it Creamy (Optional):** For a creamier soup, use an immersion blender to partially blend the soup before adding the kale. Be careful not to over-blend, as you want to retain some texture.
* **Add Protein:** For a heartier and more filling soup, add cooked lentils, beans, chickpeas, or shredded chicken.
* **Make it Vegan:** To ensure the soup is vegan, use vegetable broth and omit the Parmesan rind (if using).
* **Storage:** Leftover soup can be stored in an airtight container in the refrigerator for up to 3-4 days. It can also be frozen for longer storage (up to 2-3 months). Thaw completely before reheating.
* **Reheating:** Reheat the soup gently on the stovetop over medium heat or in the microwave until heated through.
Variations
* **Spicy Roasted Vegetable and Kale Soup:** Add more red pepper flakes or a pinch of cayenne pepper for extra heat.
* **Creamy Roasted Vegetable and Kale Soup:** Blend a portion of the soup with an immersion blender for a creamier texture. You can also add a splash of coconut milk or heavy cream for richness.
* **Roasted Vegetable and Kale Soup with Sausage:** Add browned Italian sausage or chorizo for a heartier and more flavorful soup.
* **Lemon Roasted Vegetable and Kale Soup:** Add the zest and juice of one lemon to brighten the flavors and add a zesty touch.
* **Mediterranean Roasted Vegetable and Kale Soup:** Use Mediterranean herbs like oregano and basil, and add a can of chickpeas and some chopped sun-dried tomatoes.
Serving Suggestions
* Serve with crusty bread for dipping.
* Top with a dollop of plain yogurt or sour cream.
* Garnish with fresh herbs like parsley, cilantro, or basil.
* Sprinkle with grated Parmesan cheese or nutritional yeast (for a vegan option).
* Serve alongside a grilled cheese sandwich or a green salad.
