This roasted tomato soup delivers deep, sweet, and smoky flavors thanks to a simple but transformative step: roasting. By caramelizing tomatoes, onions, bell peppers, and garlic in the oven, you build a rich foundation that no stovetop simmer can match. And while a hand blender works in a pinch, a high-speed blender makes a noticeable difference—turning the mixture into a luxuriously smooth, restaurant-quality soup.
For best results, use ripe, in-season tomatoes. Their natural sweetness and acidity shine through after roasting, creating a balanced, vibrant base. This recipe serves four and comes together in under an hour, with only 5 minutes of active prep.
Ingredients
- 1½ pounds ripe tomatoes, cored (if needed) and quartered
- 1 large red bell pepper, seeded and quartered
- 3 medium yellow onions, peeled and quartered
- Extra-virgin olive oil
- 5 plump garlic cloves, unpeeled
- 1 teaspoon fine-grain sea salt, plus more to taste
- 2–3 cups hot vegetable stock or water
- 1 teaspoon smoked paprika
- ½ teaspoon cayenne powder (optional)
Topping ideas: toasted sesame seeds, extra smoked paprika, crumbled goat cheese, fresh chives
Instructions
Preheat your oven to 375°F (190°C). Position two racks in the middle and line two rimmed baking sheets with parchment paper—or lightly coat them with olive oil.
Arrange the tomatoes skin-side down on one sheet. On the other, toss the bell pepper, onions, and garlic cloves with olive oil. Place the pepper skin-side down as well. Sprinkle both sheets lightly with salt.
Roast for about 45 minutes, or until the tomatoes collapse and the onions turn golden and caramelized. If the onions darken too quickly, flip them halfway through. Check the garlic early—once the cloves are soft and golden inside, remove them to cool.
Let the vegetables cool slightly. Then peel the garlic and add all roasted ingredients to a high-speed blender. Start with 1 cup of hot stock and blend until smooth. Gradually add more stock, ½ cup at a time, until you reach your preferred consistency.
Stir in the smoked paprika and cayenne (if using). Season with additional salt to taste.
Serve warm, generously topped with your favorites—goat cheese for creaminess, chives for freshness, sesame seeds for crunch, or a dusting of paprika for color and warmth.
Why Roasting Makes the Difference
Roasting concentrates flavor and adds natural sweetness through caramelization. The garlic becomes mellow and buttery, while the bell pepper lends subtle depth. Blending while warm ensures a silky texture without needing cream or thickeners.
This roasted tomato soup is naturally vegetarian, easily vegan (skip the cheese), and perfect for showcasing summer’s best tomatoes. Make it once, and you’ll never go back to canned versions again.
