Preparation Phase & Tools to Use

Before diving into the soup-making process, here’s what you’ll need and why each tool matters:

• Baking Sheet: Essential for roasting tomatoes and garlic evenly, bringing out their natural sweetness.
• Blender or Immersion Blender: To achieve that silky-smooth texture. Immersion blenders are great for less cleanup, while standard blenders work best for ultra-velvety finishes.
• Large Pot or Dutch Oven: Perfect for sautéing aromatics and simmering the soup.
• Fine Mesh Strainer (optional): If you prefer a smoother, seed-free soup.
• Ladle: For easy and mess-free serving.

How To Make the Perfect Roasted Tomato Basil Soup

Step 1: Roast the Vegetables

Preheat your oven to 400°F (200°C). Place halved tomatoes, garlic cloves (skins on), and sliced onions on a baking sheet. Drizzle generously with olive oil and a sprinkle of salt. Roast for 30-35 minutes until caramelized and slightly charred.

Step 2: Sauté the Aromatics

In a large pot or Dutch oven, heat a tablespoon of olive oil. Remove roasted garlic from its skin and add to the pot along with the roasted onion and tomatoes. Cook on medium heat for 5 minutes to deepen the flavor.

Step 3: Simmer with Broth

Pour in the vegetable broth and let everything simmer together for 15-20 minutes. This allows the flavors to fully blend.

Step 4: Blend Until Smooth

Use an immersion blender directly in the pot or transfer the mixture in batches to a blender. Blend until smooth and creamy. If desired, strain the soup through a mesh sieve for an ultra-smooth finish.

Step 5: Add Basil and Finish

Stir in fresh basil leaves and simmer for another 5 minutes. Add cream if using, and season to taste with salt and pepper.
