Instructions

Preheat oven to 375°F (190°C). Arrange Roma tomatoes on a baking sheet, drizzle with olive oil, season with salt and pepper, and roast for 1 hour until caramelized.
In a Dutch oven, melt butter and sauté onion for 5 minutes until softened.
Add garlic, thyme, salt, and pepper; cook 1 minute until fragrant.
Stir in crushed San Marzano tomatoes, basil, and sugar. Simmer gently for 10 minutes.
Add roasted tomatoes and chicken stock. Simmer 30 minutes, stirring occasionally.
Blend with an immersion blender (or carefully in a regular blender) until smooth.
Stir in heavy cream and warm through. Adjust seasoning to taste.
Serve hot with croutons, crusty bread, or grilled cheese.

Notes

Roasting tomatoes deepens their sweetness—don’t skip this step.

For a chunkier soup, only blend half of the mixture.

Swap heavy cream with half-and-half or coconut milk for a lighter/dairy-free version.

Add carrots or red peppers for extra sweetness and depth.

Freezes beautifully—add cream after reheating for best texture.
