Step-by-step guide to making sweet potato carrot soup

1. Preheat your oven to 200°C (400°F).
2. Peel and chop 2 large sweet potatoes and 3 carrots into even chunks.
3. Toss the vegetables with olive oil, salt, and a pinch of pepper. Spread on a baking sheet.
4. Roast for about 30-35 minutes, stirring halfway, until they’re caramelized and tender.
5. In a large pot, sauté 1 chopped onion and 2 minced garlic cloves in a splash of oil until fragrant, about 5 minutes.
6. Add the roasted vegetables to the pot. Pour in 4 cups of vegetable broth.
7. Bring to a boil, then reduce heat and simmer for 10 minutes, letting the flavors meld.
8. Use an immersion blender or transfer to a blender to puree the soup until smooth.
9. Taste and adjust seasoning—add salt, pepper, and a squeeze of lemon if desired.

How to Know It’s Done

• Soup is smooth and velvety when blended.
• A slight caramelized smell indicates good roasting.
• Soup should be hot and steaming when served.

Tips and tricks for perfect soup

• FLAVOR: Roast the vegetables until slightly charred for a smoky depth.
• TEXTURE: Puree in stages if the soup is too thick, to avoid strain.
• AROMA: Add a sprig of thyme during simmering for subtle herbal notes.
• HEAT: Keep the soup at a gentle simmer—boiling too hard can break down the vegetables.
• BALANCE: Finish with a squeeze of lemon to brighten the sweetness.

Common mistakes and how to fix them

• FORGOT TO peel the vegetables? Just scrape the skins off after roasting for a smoother soup.
• DUMPED too much broth? Add a splash of water or more roasted veggies to balance.
• OVER-TORCHED the garlic? Discard and start fresh—bitter tastes ruin the sweetness.
• SCOURED the bottom of the pot? Deglaze with a little broth to lift the caramelized bits.

Quick fixes for common issues

• When too thick, splash in hot water or broth and blend again.
• Splash a little vinegar if the soup tastes flat.
• Patch blandness by stirring in a dash of soy sauce or miso.
• Shield burnt bits with a splash of water and scrape up the flavor.
• Shimmer with a drizzle of olive oil or cream for richness.

Make-ahead tips and storage notes

• Soup can be made 2 days in advance; reheat gently on the stove, stirring often.
• The flavors deepen overnight, making it even more comforting.
• Reheat the soup on low heat until steaming, checking for even warmth and adjusting seasoning as needed.
