Description

A comforting and flavorful Roasted Tomato Basil Soup that is simple to prepare and perfect for chilly evenings.


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
  • ⅔ cup heavy cream

Instructions

  1. Preheat your oven to 375°F (190°C). Spread the ripe tomato halves on a baking sheet, drizzle with olive oil, and sprinkle with salt and pepper.
  2. Roast the tomatoes in the oven for about an hour until they are caramelized and fragrant. Once done, remove them from the oven and set aside.
  3. In a large pot or Dutch oven, heat the butter and remaining olive oil over medium-high heat. Add the diced onion and sauté for about 5 minutes until the onions become translucent.
  4. Stir in the minced garlic and thyme, and sauté for another minute until fragrant.
  5. Add the crushed San Marzano tomatoes, fresh basil, and sugar to the pot, then lower the heat and allow it to simmer for about 10 minutes.
  6. Incorporate the roasted tomatoes and chicken stock into the pot and let everything simmer for an additional 30 minutes, stirring occasionally.
  7. Use an immersion blender to purée the soup until smooth; alternatively, carefully transfer to a blender in small batches. Return the puréed soup to the pot.
  8. Stir in the heavy cream to create a creamy and luscious texture.
  9. Serve the soup hot, garnished with homemade croutons or freshly chopped basil.

Perfect Pairings for This Dish

When it comes to enjoying this Roasted Tomato Basil Soup, there are some perfect pairings that really elevate the experience. Try serving it alongside a warm, crusty loaf of sourdough bread or classic grilled cheese sandwiches for a hearty meal. A light, crisp salad makes a refreshing complement, balancing out the rich flavors of the soup. Drink-wise, a chilled glass of white wine such as Sauvignon Blanc or even a sparkling water with a twist of lemon can be delightful company.

Make-Ahead & Storage Tips

This Roasted Tomato Basil Soup is not only satisfying when made fresh, but it also stores beautifully! To keep it fresh, allow the soup to cool completely before transferring it to airtight containers. Store in the refrigerator for up to four days or freeze for up to three months. When reheating, simply warm it on the stove over low heat, adding a splash of chicken stock or heavy cream if it thickens too much.

Tips for Perfect Results

  1. For maximum flavor, roast your tomatoes until they are caramelized and bubbling — it’s well worth the wait!
  2. Adjust the thickness of the soup by varying the amount of chicken stock added when blending — keep it thick and hearty or thin it to your desire.
  3. If you prefer a more intense basil flavor, feel free to add a little extra as it simmers.
  4. Don’t skip the sugar; it helps balance the acidity of the tomatoes perfectly.
  5. For a creamier texture, consider blending in a bit more heavy cream or even some mascarpone at the end.

Creative Twists to Try

Feeling adventurous? Here are a few flavor twists you can experiment with to keep this recipe fresh:

  • Spice things up by adding a pinch of red pepper flakes or a drizzle of chili oil for that extra kick.
  • Swap out the basil for fresh oregano or parsley for a different herbal vibe.
  • Combine in some roasted red peppers for a smoky flavor that adds depth to your soup.
