How to Make Tomato Basil Soup

Making this soup is a rewarding, multi-step process that fills your kitchen with amazing aromas. Here’s how:

1. Roast the Tomatoes

• Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
• Slice 2½ pounds of roma tomatoes in half vertically and place them cut-side up on the sheet.
• Drizzle with olive oil, season with salt and pepper.
• Roast for about 1 hour, or until the tomatoes are juicy but beginning to shrivel along the edges.

2. Sauté Aromatics

• Heat remaining olive oil in a large pot over medium heat.
• Add chopped onion, carrot, and garlic along with some salt.
• Cook for 8 minutes, until soft and fragrant.

3. Simmer the Soup

• Add the roasted tomatoes, 3 cups vegetable broth, balsamic vinegar, and fresh thyme to the pot.
• Bring to a boil, then reduce heat and simmer gently for 20 minutes to develop flavor.

4. Blend Until Creamy

• Let the mixture cool slightly.
• Transfer soup to a blender in batches, or use an immersion blender directly in the pot.
• Blend until completely smooth.
• Add 1 packed cup of fresh basil leaves and pulse briefly until combined for a flecked green appearance and vivid flavor.

5. Season & Serve

• Taste the soup; adjust seasoning with salt, pepper, or more vinegar if needed.
• Ladle into bowls and garnish with extra basil leaves.

Tips for the Best Tomato Basil Soup

• Choose the right tomatoes: Roma or plum tomatoes are less watery and more flavorful. Avoid large heirloom or salad tomatoes for this recipe.
• Blend in basil at the end: This keeps its flavor fresh and the color vivid.
• Don’t skip the roasting: Roasting intensifies and caramelizes the tomato flavor.
• For creamier soup: Add more carrots or use a splash of coconut milk for a dairy-free option.
• Freeze extra soup: Cool completely and store in an airtight container for up to 3 months. Thaw and reheat gently.

Serving Suggestions

This soup is satisfying on its own, but truly shines with the right sides:

• Classic Grilled Cheese: The ultimate partner! Crunchy bread and melty cheese are perfect for dunking.
• Crusty Bread: Dip a thick slice into your bowl for a rustic, comforting meal.
• Salad: Pair with a simple mixed green salad dressed with balsamic vinaigrette.
• Herb Swirl: Garnish each bowl with a swirl of olive oil and a sprinkle of chopped fresh basil.

Recipe Variations

• Spicy Tomato Basil Soup: Add a pinch of crushed red pepper flakes while sautéing the aromatics.
• Coconut Tomato Basil Soup: Swirl in a little coconut milk at the end for a non-dairy creamy touch.
• Cheesy Finish: Top each serving with freshly grated Parmesan cheese for extra richness.
• More Garlic: For garlic lovers, feel free to increase the amount for extra punch.
• Add greens: Stir in baby spinach or kale for more nutrition and color.

Frequently Asked Questions (FAQs)

Q: Can I use canned tomatoes instead of fresh?

A: For this recipe, fresh roma or plum tomatoes are best to achieve the deep roasted flavor. Canned tomatoes work, but the soup will lack the same roasted, caramelized notes. If you use canned, skip the roasting and simmer a bit longer with the aromatics.

Q: Do I need to peel the tomatoes before roasting?

A: No, there is no need to peel the tomatoes. The skins blend smoothly into the soup and add flavor once pureed.

Q: How long does tomato basil soup last in the fridge?

A: Store cooled soup in an airtight container for up to 4 days in the refrigerator.

Q: Can I freeze this soup?

A: Absolutely! Let the soup cool completely, then freeze in meal-sized containers for up to 3 months. Thaw overnight in the fridge and reheat gently.

Q: How can I make this soup vegan or dairy-free?

A: This recipe is naturally vegan and dairy-free as written, thanks to the use of olive oil and carrots for creaminess. Avoid adding cheese or butter for keeping it fully plant-based.
