Spicy Roasted Vegetable Soup with Leftover Grilled Meat

The aroma of roasting vegetables, kissed with balsamic vinegar and herbs, always takes me back to my grandmother’s kitchen. She had a knack for turning even the humblest ingredients into something extraordinary. One autumn, after a particularly bountiful harvest and a family barbecue, she tossed the leftover grilled chicken and roasted veggies into a pot with some broth. The result was a surprisingly delicious and comforting soup that warmed us from the inside out. This recipe is my tribute to her resourceful spirit and her ability to transform simple leftovers into a memorable meal.

• Dietary Type: Varies (see variations)

Ingredients

Grilling Leftovers:

• 1 cup cooked chicken (or beef or pork, shredded or thinly sliced)
• ½ cup marinade (from the cooked meat)

Optional Roasting Vegetables (8-10 cups total):

• 1 cup sweet potato (1 inch cubes)
• 1 cup baby potatoes (quartered)
• 1 cup turnip (1 inch cubes)
• 1 cup parsnip (1-1/2 inch lengths, halved)
• 1 cup carrot (1-1/2 inch lengths, halved)
• 1 cup broccoli florets
• 1 cup cauliflower florets
• 1 cup Brussels sprouts (halved)
• 1 eggplant (1-1/2 inch cubes)
• 4 celery ribs (1-1/2 inch lengths)
• 1 cup asparagus spears (1-1/2 inch lengths)
• 1 cup zucchini (1-1/2 inch lengths, halved or quartered, depending on diameter)

Roasting Spices and Soup Base:

• 1 large red onion (1-1/2 inch dice)
• 1 large red pepper (1-1/2 inch dice)
• 5 garlic cloves (minced)
• ⅓ cup olive oil
• ¼ cup balsamic vinegar
• 1 teaspoon dried basil
• 1 teaspoon dried thyme
• 1 teaspoon dried oregano
• ½ teaspoon fresh coarse ground black pepper
• 6 cups broth (beef, chicken, or vegetable)

Equipment Needed

• 2 large sheet pans
• Foil
• Large bowl
• Whisk
• Large soup pot

Instructions

1. Begin by preheating your oven to 425 degrees F (220 degrees C). Line 2 large sheet pans with foil and coat them generously with non-stick cooking spray. This prevents sticking and makes cleanup a breeze.

2. In a large bowl, prepare the spice mixture. Add the dried basil, dried thyme, and dried oregano, along with the fresh coarse ground black pepper. Pour in the olive oil and balsamic vinegar, then add the minced garlic. Use a whisk to thoroughly combine all the ingredients. This creates a flavorful base for your roasted vegetables.

3. Prepare your vegetables. You’ll need about 8-10 cups total. Add the sweet potato, baby potatoes, turnip, parsnip, carrot, broccoli florets, cauliflower florets, Brussels sprouts, eggplant, celery ribs, asparagus spears, zucchini, red onion, and red pepper to the bowl with the vinegar mixture. Using your hands, turn the vegetables over to ensure they are evenly coated with the oil and spice mixture. The balsamic vinegar will add a touch of sweetness and acidity that complements the spices perfectly.

4. Arrange the vegetables on the prepared baking sheets in a single layer. It’s important to separate the firm-fleshed vegetables (like sweet potatoes, carrots, and turnips) from the faster-cooking, softer ones (like zucchini and eggplant). This ensures that everything roasts evenly without some vegetables becoming mushy.

5. Roast the vegetables at 425 degrees F (220 degrees C) for about 20 minutes, then turn them over with a spatula. At around 25 minutes, remove the faster-cooking vegetables (like the zucchini and eggplant) before they become too soft. Reserve these in a separate bowl while the firmer vegetables continue to cook. This staged roasting approach is key to achieving perfectly caramelized vegetables. The firmer vegetables may need closer to 35 minutes to be tender.

6. Once all the vegetables have caramelized to your liking, combine them in a large soup pot along with the cooked chicken (or beef or pork), leftover marinade, and broth. Note: reserve the eggplant, zucchini and red pepper. Bring the mixture to a simmer over medium-low heat and cook for about 20 minutes. Now add the eggplant, zucchini, and red pepper. Continue to simmer for another 10-15 minutes, or until all the vegetables are fork-tender. This final simmering allows the flavors to meld together beautifully, creating a rich and satisfying soup.

7. Serve hot and enjoy!

Expert Tips & Tricks

• Maximize Caramelization: For extra caramelization, don’t overcrowd the baking sheets. Overcrowding steams the vegetables instead of roasting them.
• Spice it Up: Add a pinch of red pepper flakes to the spice mixture for an extra kick.
• Deglaze the Pan: After roasting the vegetables, deglaze the baking sheets with a splash of broth or wine to capture all those flavorful browned bits. Add this to the soup for an extra layer of flavor.
• Make Ahead: The roasted vegetables can be prepared a day or two in advance and stored in the refrigerator. This makes the soup-making process even quicker on a busy weeknight.

Serving & Storage Suggestions

Serve this Spicy Roasted Vegetable Soup hot with a side of crusty bread for dipping. A dollop of plain yogurt or a swirl of pesto adds a touch of richness and flavor.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. For longer storage, freeze the soup in individual portions. To reheat, simply warm the soup in a saucepan over medium heat or microwave until heated through.

FAQs (Frequently Asked Questions)

Q: Can I use frozen vegetables in this soup?
A: Yes, frozen vegetables can be used, but they may release more water during cooking. Adjust the simmering time accordingly and drain off any excess liquid if necessary.

Q: What if I don’t have balsamic vinegar?
A: You can substitute with red wine vinegar or apple cider vinegar. These will provide a similar tanginess.

Q: Can I use other types of meat besides chicken, beef, or pork?
A: Absolutely! Lamb, turkey, or even sausage would work well in this soup.

Q: How do I make this soup thicker?
A: You can puree a portion of the soup with an immersion blender or in a regular blender (carefully!). Alternatively, you can add a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water) to the soup during the last 10 minutes of simmering.

Q: Can I add beans to this soup?
A: Yes, adding beans is a great way to boost the protein and fiber content. Cannellini beans, kidney beans, or chickpeas would all be excellent choices. Add them during the last 15 minutes of simmering.
