Introduction
What if the secret to the most flavorful tomato soup wasn’t in a simmering pot, but in your oven? A 2020 study published in the Journal of Food Science found that roasting tomatoes significantly increases their umami flavor and overall acceptability compared to boiling or stewing (source: https://ift.onlinelibrary.wiley.com/doi/abs/10.1111/1750-3841.15334). This method transforms ordinary tomatoes into a sweet, caramelized base for an incredible Easy Roasted Tomato Soup.
This recipe leverages that simple scientific principle for maximum flavor with minimal effort. By roasting the tomatoes with garlic and onions, you create a deep, complex taste profile that forms the heart of this comforting dish. It’s a hands-off approach that yields a far superior result to any canned version, proving that the best meals are often the simplest to make.

Step-by-Step Instructions
Step 1 — Preheat Oven and Prepare Tomatoes
Preheat your oven to 400°F (200°C). While the oven heats, wash and core 3 pounds of ripe Roma or plum tomatoes. Cut them in half lengthwise and place them cut-side up on a large, rimmed baking sheet.
Step 2 — Season the Tomatoes
Drizzle the tomato halves with 3 tablespoons of olive oil and season generously with salt and black pepper. For added depth, you can also sprinkle with a teaspoon of dried oregano or thyme.
Step 3 — Roast the Tomatoes
Place the baking sheet in the preheated oven and roast for 35-40 minutes. The tomatoes are done when their skins have wrinkled and begun to caramelize at the edges, and they have released their juices onto the pan.
Step 4 — Sauté Aromatics
While the tomatoes roast, heat a tablespoon of olive oil in a large pot or Dutch oven over medium heat. Add one diced medium onion and cook for 5-7 minutes until softened and translucent. Add 3-4 minced garlic cloves and cook for another minute until fragrant.
Step 5 — Combine and Simmer
Once the tomatoes are finished roasting, carefully transfer them and all the pan juices into the pot with the aromatics. Add 4 cups of vegetable or chicken broth and bring the mixture to a boil. Reduce the heat to low and let it simmer for 15 minutes.
Step 6 — Blend the Soup
Use an immersion blender directly in the pot to puree the soup until completely smooth. Alternatively, carefully blend the soup in batches using a countertop blender. For an extra silky texture, you can pass the blended soup through a fine-mesh sieve.
Step 7 — Final Seasoning and Serve
Taste the soup and adjust seasoning with more salt and pepper if needed. For a touch of richness, stir in a quarter cup of heavy cream or a swirl of extra virgin olive oil. Serve your Easy Roasted Tomato Soup hot, garnished with fresh basil or croutons.
