There’s a kind of magic that happens when vegetables roast in the oven—the edges caramelize, their natural sweetness deepens, and suddenly the simplest ingredients turn into something extraordinary. That’s the heart and soul of this Roasted Vegetable Soup.
I first made this soup on a snowy January afternoon. The house was quiet, the windows steamed, and I needed something comforting yet wholesome. I gathered what I had—root vegetables, a head of garlic, and a few forgotten tomatoes. I roasted them until golden and bubbling, then blended everything with vegetable broth. The result? A velvety, rich soup with layers of smoky, sweet, and savory flavor. It was the kind of meal that warms your bones and makes you feel cared for.
This recipe is a nod to humble kitchen traditions—using what’s on hand, cooking with intention, and letting the oven do the heavy lifting. Whether you’re looking for a way to use up leftover vegetables, need a meal-prep friendly soup, or just crave something cozy and nourishing, this roasted vegetable soup will wrap you up like your favorite blanket.

- ½ teaspoon dried rosemary
- 1 teaspoon salt
- ½ teaspoon black pepper
- 4 cups vegetable broth
- 1 tablespoon lemon juice (optional)

Instructions
- Preheat and prep:
Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper. - Prepare the vegetables:
Place carrots, parsnips, sweet potato, red pepper, onion, zucchini, tomatoes, and garlic cloves on the baking sheet. Drizzle with olive oil and sprinkle with thyme, rosemary, salt, and pepper. Toss to coat evenly. - Roast the vegetables:
Roast for 30–35 minutes, stirring once halfway through, until everything is tender and slightly browned. The garlic should be soft and fragrant. - Blend the soup:
Remove the garlic cloves from their skins and place all the roasted vegetables into a blender. Add vegetable broth and blend until smooth. You may need to do this in batches depending on the size of your blender. - Simmer and season:
Pour the blended soup into a large pot and bring to a gentle simmer over medium heat. Adjust seasoning to taste. Add lemon juice if desired for brightness. - Serve:
Ladle into bowls and garnish with fresh herbs. Serve with crusty bread or a swirl of non-dairy cream.
