Can I make this soup ahead of time?
Yes. Refrigerate for up to 4 days, or freeze for up to 3 months. Reheat gently on the stovetop, adding broth or water if needed to reach desired consistency.
What's the purpose of roasting the vegetables?
Roasting caramelizes the natural sugars in tomatoes, peppers, and garlic, creating depth and sweetness without added sugar. It also softens them for smooth blending.
Can I use canned tomatoes instead of fresh?
Yes, use 2 cans (28 oz each) of crushed or whole tomatoes. Roasting is optional but recommended; you can roast them in a shallow pan or go straight to blending with the other roasted vegetables.
How do I adjust the soup's thickness?
Blend longer for creamier texture, or blend less for a chunkier consistency. Add vegetable broth or water to thin, or simmer uncovered to reduce and thicken.
Can I skip the Greek yogurt?
Yes. For creaminess, substitute heavy cream, coconut milk, or whole milk. The soup is also delicious without added cream.
