Step-by-Step Instructions

Step 1 — Preheat and Prepare

Preheat your oven to 400°F (200°C). While it heats, wash and halve about 2 pounds of ripe tomatoes, placing them cut-side up on a large baking sheet.

Drizzle generously with olive oil and season with salt and black pepper. This initial roasting step deepens the flavor of your Roasted Tomato Basil Soup.

Step 2 — Roast the Tomatoes

Place the baking sheet in the preheated oven and roast for 30–40 minutes. You’ll know they’re ready when the tomatoes are soft, slightly caramelized, and their skins have begun to wrinkle.

For extra flavor, add a few unpeeled garlic cloves to the pan to roast alongside the tomatoes.

Step 3 — Sauté Aromatics

While the tomatoes roast, heat a tablespoon of olive oil in a large pot over medium heat. Add one chopped medium onion and cook until soft and translucent, about 5–7 minutes.

Step 4 — Combine and Simmer

Once the tomatoes and garlic are out of the oven, carefully squeeze the roasted garlic from its skin into the pot with the onions. Add the roasted tomatoes and any juices from the pan.

Pour in 4 cups of vegetable broth, bring to a boil, then reduce the heat and let it simmer for 15 minutes to allow the flavors to meld.

Step 5 — Blend the Soup

Remove the pot from the heat and let it cool slightly. Use an immersion blender directly in the pot to puree the soup until completely smooth.

Alternatively, carefully blend in batches using a countertop blender, ensuring you do not fill it more than halfway to prevent hot soup from splattering.

Step 6 — Stir in Fresh Basil and Cream

Once the soup is smooth, stir in ½ cup of fresh chopped basil leaves. For a creamier Roasted Tomato Basil Soup, you can also stir in ¼ cup of heavy cream or a dairy-free alternative at this stage.

Step 7 — Final Seasoning and Serve

Taste the soup and adjust the seasoning with more salt and pepper as needed. For a touch of acidity, a teaspoon of balsamic vinegar can brighten the flavors beautifully.

Ladle the hot Roasted Tomato Basil Soup into bowls and serve immediately, garnished with an extra basil leaf if desired.

Common Mistakes to Avoid

• Mistake: Using out-of-season tomatoes, which are watery and lack flavor. Fix: Opt for Roma or canned San Marzano tomatoes for a consistently rich, sweet base year-round.
• Mistake: Not roasting the tomatoes long enough, resulting in a flat, acidic soup. Fix: Roast until the tomatoes are deeply caramelized and collapsing to concentrate their natural sugars.
• Mistake: Adding basil too early in the cooking process. Fix: Stir in fresh basil just before blending to preserve its bright, aromatic flavor and vibrant green color.
• Mistake: Blending the soup while it’s still piping hot. Fix: Allow the soup to cool slightly before blending to prevent steam pressure from causing a messy and dangerous explosion.
• Mistake: Over-blending, which can incorporate too much air and make the soup foamy. Fix: Pulse in short bursts until smooth for a velvety, restaurant-quality texture.
• Mistake: Skipping the acid balance at the end. Fix: Finish with a splash of balsamic vinegar or a squeeze of lemon juice to brighten all the flavors.
• Mistake: Using a weak, store-bought broth that dilutes the tomato flavor. Fix: Use a high-quality vegetable or chicken broth, or even water, to let the roasted tomato flavor shine.
• Mistake: Not adjusting the soup’s consistency after blending. Fix: Thin it with more broth or cream to your desired thickness for the perfect spoonable texture.
• Mistake: Forgetting to season in layers throughout cooking. Fix: Season the tomatoes before roasting and again after blending for a fully developed, well-seasoned Roasted Tomato Basil Soup.
• Mistake: Rushing the final simmer after blending. Fix: Let the soup simmer gently for 10-15 minutes to allow the flavors to fully meld together.

Storing Tips

• Fridge: Store your Roasted Tomato Basil Soup in an airtight container for up to 4 days. Ensure it cools to room temperature before refrigerating.
• Freezer: Freeze the soup in freezer-safe containers or heavy-duty bags for up to 3 months. Leave some space at the top for expansion.
• Reheat: Reheat gently on the stovetop or in the microwave, stirring occasionally, until it reaches an internal temperature of 165°F for food safety.

For best quality, thaw frozen Roasted Tomato Basil Soup overnight in the refrigerator before reheating.
