Ingredients

This Roasted Tomato Basil Soup comes together with simple, fresh ingredients that create a rich, velvety texture and deep, caramelized flavor.

• 3 pounds ripe tomatoes, halved
• 1 large onion, quartered
• 6 cloves garlic, peeled
• 3 tablespoons olive oil

• 1/2 cup fresh basil leaves, chopped

Step-by-Step Instructions

Step 1 — Preheat Oven and Prepare Tomatoes

Preheat your oven to 400°F (200°C). While it heats, wash and halve 3 pounds of ripe Roma or plum tomatoes. Place them cut-side up on a large, rimmed baking sheet.

Step 2 — Season and Roast Tomatoes

Drizzle the tomatoes generously with olive oil and season with salt and black pepper. Roast for 35-40 minutes until the skins are blistered and the edges are slightly caramelized. This roasting deepens the flavor of your Roasted Tomato Basil Soup.

Step 3 — Sauté Aromatics

While tomatoes roast, heat 2 tablespoons of olive oil in a large pot over medium heat. Add 1 chopped onion and 4 minced garlic cloves, sautéing until soft and fragrant, about 5-7 minutes.

Step 4 — Combine and Simmer

Add the roasted tomatoes and any juices from the pan to the pot. Stir in 4 cups of vegetable broth and a handful of fresh basil leaves. Bring to a boil, then reduce heat and let it simmer for 15 minutes to allow the flavors to meld.

Step 5 — Blend the Soup

Carefully blend the soup until smooth using an immersion blender directly in the pot. Alternatively, transfer in batches to a countertop blender, but be sure to allow steam to escape to avoid splatters.

Step 6 — Adjust Consistency and Seasoning

If the Roasted Tomato Basil Soup is too thick, add more broth or a splash of cream until it reaches your desired consistency. Taste and adjust seasoning with more salt and pepper if needed.

Step 7 — Final Simmer and Serve

Let the soup simmer for another 5 minutes on low heat. Serve hot, garnished with fresh basil, a drizzle of cream, or a sprinkle of Parmesan cheese.

Common Mistakes to Avoid

• Mistake: Using underripe, out-of-season tomatoes. Fix: Opt for Roma or plum tomatoes, which have less water and more concentrated flavor, especially when roasted.
• Mistake: Overcrowding the roasting pan. Fix: Spread tomatoes in a single layer to ensure proper caramelization, not steaming.
• Mistake: Adding basil too early in cooking. Fix: Stir in fresh basil just before blending to preserve its bright, aromatic flavor.
• Mistake: Skipping the roasting step for garlic. Fix: Roast garlic cloves with the tomatoes to mellow their sharpness and add a sweet, nutty depth.
• Mistake: Blending the soup while it’s too hot. Fix: Let the soup cool slightly to avoid pressure buildup and potential splatters from your blender.
• Mistake: Not adjusting the soup’s consistency after blending. Fix: Thin with broth or cream to your desired texture; it often thickens upon standing.
• Mistake: Forgetting to season in layers. Fix: Season tomatoes before roasting, then taste and adjust again after blending for a perfectly balanced Roasted Tomato Basil Soup.
• Mistake: Using a weak blender. Fix: A high-powered blender ensures an ultra-smooth, velvety texture that defines a great tomato soup.

Storing Tips

• Fridge: Cool completely, then store in an airtight container for up to 4 days.
• Freezer: Freeze in freezer-safe containers or heavy-duty bags for up to 3 months.
• Reheat: Thaw if frozen, then warm on the stovetop or in the microwave until it reaches 165°F, stirring occasionally.

For best quality, avoid repeated reheating of your Roasted Tomato Basil Soup. Always use clean utensils to serve and never leave soup at room temperature for more than 2 hours.
