If you’re craving a warm, comforting, and deeply flavorful soup that tastes like it came straight from a rustic café, this Roasted Tomato Garlic Soup is the perfect recipe for you. It’s fresh, velvety, aromatic, and packed with rich flavors created through the simple magic of roasting. Unlike canned tomato soups that taste flat or overly acidic, roasting fresh tomatoes with onions and a whole head of garlic transforms them into something incredible. The tomatoes become naturally sweet and caramelized, the garlic turns buttery and mellow, and the onions develop a deep golden richness. Together, they create a base that feels luxurious even before you add the broth or cream. This soup has the perfect balance of sweetness, warmth, and herbal depth, thanks to dried basil, thyme, and just the right amount of red pepper flakes. A splash of heavy cream adds smoothness without making the soup heavy. It’s cozy, nourishing, and deeply satisfying — the kind of recipe that warms your hands, heart, and soul. It’s ideal for chilly fall evenings, winter comfort meals, rainy days, cozy Sunday dinners, or simply when you want something fresh and homemade. Pair it with grilled cheese, toasted sourdough, garlic croutons, or even enjoy it plain. No matter how you serve it, this soup is a masterpiece of simple ingredients layered with big flavor.
Preheat your oven to 425°F (220°C).
Slice tomatoes in half and spread them onto a baking sheet.
Cut the top off the garlic bulb, drizzle with olive oil, wrap completely in foil, and place on the tray.
Scatter onion wedges around the tomatoes.
Drizzle everything with olive oil, then season with salt and black pepper.
Roast for 25–30 minutes or until:
Tomatoes burst and caramelize
Garlic becomes buttery and soft
Onion edges turn golden
This step is key — it creates that deep, rich roasted flavor.
Step 3: Transfer to the Pot
Place roasted tomatoes and onions into a large pot.
Squeeze the softened garlic cloves out of the bulb and into the pot.
Add:
Dried basil
Dried thyme
Red pepper flakes
Sauté lightly for 2 minutes to bloom the spices.
Pour in vegetable broth.
Stir everything together.
Simmer for 10 minutes to blend the flavors.
Use an immersion blender in the pot
—or carefully transfer to a regular blender—
Blend until smooth, creamy, and velvety.
Taste and adjust:
Salt
Pepper
Herbs
Stir in the heavy cream.
Simmer gently for 2–3 minutes more.
Do not boil hard — low heat keeps the cream smooth.
Ladle into warm bowls.
Top with:
Fresh basil or parsley
Cracked black pepper
A swirl of cream
A drizzle of olive oil
Serve with garlic bread, croutons, or grilled cheese.
