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. Scoop out the seeds with a spoon for a less watery soup.

Tip: Use a rimmed baking sheet to catch any juices and prevent mess.

Step 2 — Season and Roast Tomatoes

Arrange the tomato halves cut-side up on the baking sheet. Drizzle generously with olive oil and season with salt and black pepper. Roast for 30-40 minutes until the tomatoes are soft and the edges begin to caramelize.

Doneness cue: Look for slight charring and wrinkling on the skins.

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.

Tip: Avoid browning the garlic to prevent bitterness.

Step 4 — Combine and Simmer

Add the roasted tomatoes and any pan juices 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 simmer for 15 minutes.

Step 5 — Blend the Soup

Carefully puree the soup using an immersion blender directly in the pot until smooth. Alternatively, blend in batches in a countertop blender, ensuring the lid is vented to avoid steam pressure.

Safety tip: Let the soup cool slightly before blending to prevent splatters.

Step 6 — Adjust Consistency and Seasoning

If the Roasted Tomato Basil Soup is too thick, add more broth or a splash of water. Season with additional salt, pepper, and a pinch of sugar if the tomatoes are acidic.

Step 7 — Finish and Serve

Stir in ¼ cup of heavy cream or coconut milk for richness, if desired. Ladle the soup into bowls and garnish with fresh basil, a drizzle of olive oil, or croutons.

Serve hot alongside crusty bread for a complete meal.

Common Mistakes to Avoid

• Mistake: Using underripe or out-of-season tomatoes, which lack sweetness and depth. Fix: Opt for ripe, in-season Roma or San Marzano tomatoes for a more concentrated, robust flavor.
• Mistake: Not roasting the tomatoes long enough, resulting in a flat, watery soup. Fix: Roast until the tomatoes are deeply caramelized and have released their juices, about 30-40 minutes at 400°F (200°C).
• Mistake: Adding basil too early in the cooking process, causing it to turn brown and bitter. Fix: Stir in fresh basil leaves just before blending to preserve their bright, aromatic quality.
• Mistake: Skipping the step of blending the soup until completely smooth. Fix: Use a high-powered blender or immersion blender to achieve a velvety, luxurious texture without any chunks.
• Mistake: Forgetting to balance the acidity of the tomatoes, which can make the soup taste sharp. Fix: A pinch of sugar or a splash of cream can mellow the acidity and round out the flavors perfectly.
• Mistake: Overlooking the importance of seasoning throughout the cooking process. Fix: Season the tomatoes before roasting and taste and adjust the salt and pepper after blending for a well-layered flavor.
• Mistake: Using a weak or inferior vegetable broth that overpowers the delicate tomato and basil. Fix: Choose a low-sodium, high-quality broth or even water to let the roasted tomato flavor shine.
• Mistake: Rushing the roasting step by crowding the pan, which steams instead of roasts the tomatoes. Fix: Spread tomatoes in a single layer on the baking sheet to ensure proper caramelization and flavor development.

Storing Tips

• Fridge: Cool completely, then store in an airtight container for up to 4 days.
• Freezer: Portion into freezer-safe bags or containers, leaving headspace; freeze for up to 3 months.
• Reheat: Warm gently on the stovetop or in the microwave, stirring occasionally, until it reaches 165°F for food safety.

This Roasted Tomato Basil Soup holds up beautifully when stored properly, making it a fantastic make-ahead meal.
