How to Make Roasted Tomato Basil Soup Recipe
Step 1: Roast the Tomatoes to Perfection
Start by preheating your oven to 375°F. Lay out your sliced Roma tomatoes on a baking sheet, then drizzle them generously with olive oil, and season with salt and pepper. Roast these beauties for a full hour. This slow roasting unlocks their natural sugars and concentrates their flavors, creating a deep, smoky sweetness that forms the soup’s soul.
Step 2: Sauté the Onion Base
While those tomatoes cook, melt your butter in a large pot over medium heat. Add the diced yellow onion and let it soften gently for about five minutes. This step builds a tender, fragrant foundation that complements the roasted tomatoes and infuses the soup with gentle savory notes.
Step 3: Incorporate Garlic and Herbs
Toss in your minced garlic and fresh thyme. Stir them around until the kitchen fills with their irresistible aroma. Season with a little more salt and pepper to taste. This step elevates your soup from good to unforgettable by layering in fresh, garden-fresh herbs and aromatic garlic.
Step 4: Add Tomatoes, Basil, and Sugar
Pour in the crushed San Marzano tomatoes along with the chopped fresh basil. Add a tablespoon of sugar to balance the acidity. Let everything simmer for 10 minutes to allow the flavors to meld into a symphony of freshness and warmth.
Step 5: Simmer with Stock and Roasted Tomatoes
Now, add your chicken stock along with the slow-roasted tomato halves straight from the oven. Let it all simmer gently for 30 minutes, giving the tomatoes time to break down and the flavors to marry into a luscious, hearty broth.
Step 6: Purée and Finish with Cream
Using an immersion blender or transferring the soup in batches to a traditional blender, purée until smooth and silky. Return the puréed soup to the pot and stir in the heavy cream. This final touch brings an indulgent creaminess that rounds out the soup perfectly and makes every spoonful feel luxuriously comforting.
Step 7: Optional Croutons for the Perfect Crunch
For those who love a little texture contrast, toss bread cubes with olive oil, minced garlic, and chopped basil, then bake them at 400°F for 7 minutes until golden and crisp. These homemade croutons are like little bursts of flavor to crown your soup.
Step 8: Serve and Enjoy
Ladle your Roasted Tomato Basil Soup Recipe into bowls, sprinkle with those crunchy croutons if you made them, and dig in. The combination of the velvety soup with the fresh herb crunch is utterly irresistible.
