Ingredients

Scale
  • 9 Roma tomatoes, sliced lengthwise

  • 3 tbsp extra virgin olive oil

  • 2 tbsp unsalted butter

  • 1 yellow onion, diced

  • 4 garlic cloves, minced

  • 1 tbsp fresh thyme, minced

  • 1 tsp Kosher salt

  • ½ tsp ground black pepper

  • 1 × 28 oz can San Marzano tomatoes, crushed

  • 1 cup fresh basil, roughly chopped

  • 1 tbsp sugar

  • 2 cups chicken stock (or vegetable stock for vegetarian option)

  • ⅔ cup heavy cream

  • Optional croutons: cubed bread tossed with olive oil, garlic, and basil, baked at 400°F for 7 minutes


Instructions

  • Preheat oven to 375°F. Arrange Roma tomatoes on a baking sheet, drizzle with olive oil, season with salt and pepper. Roast for 1 hour until soft and caramelized.

  • In a Dutch oven, melt butter over medium-high heat. Add onion and cook for 5 minutes until translucent. Stir in garlic, thyme, salt, and pepper; cook 1 minute.

  • Add crushed San Marzano tomatoes, basil, and sugar. Simmer 10 minutes.

  • Stir in roasted tomatoes and chicken stock. Simmer 30 minutes, stirring occasionally.

  • Use an immersion blender (or transfer carefully to a blender) to purée until smooth.

  • Stir in heavy cream, simmer 2–3 minutes, then serve hot with optional croutons.

Notes

Roasting tomatoes adds depth and sweetness—don’t skip this step.

Use vegetable stock to make it vegetarian-friendly.

Adjust cream for a lighter or richer texture.

Freezes beautifully—double the recipe for make-ahead meals.

Blend until silky for a restaurant-style finish.
