Ingredients
- 3 pounds ripe Roma tomatoes, halved
- 1 large yellow onion, roughly chopped
- 6 cloves garlic, peeled
- 1/4 cup extra virgin olive oil
- 1 teaspoon salt

- 1/4 teaspoon red pepper flakes (optional)

- 4 cups vegetable broth
- 1/2 cup heavy cream or coconut milk for a dairy-free option
Ingredients
Equipment
Method
- Preheat your oven to 400°F (200°C). This high heat is essential for achieving that beautiful caramelization on the tomatoes and vegetables. Line a large baking sheet with parchment paper for easy cleanup.
- Toss the halved tomatoes, chopped onion, and garlic cloves with olive oil, salt, and pepper. Spread them in a single layer on the prepared baking sheet. This ensures they roast evenly instead of steaming.
- Roast for 35–45 minutes until the tomatoes are blistered and the onion edges are lightly charred. The caramelized bits are packed with flavor, so don’t be afraid of a little color.
- Carefully transfer the roasted vegetables to a large pot. Add the vegetable broth and fresh basil. Bring the mixture to a simmer over medium heat, then cook for 10 minutes to let the flavors meld.
- Use an immersion blender to puree the soup directly in the pot until completely smooth. Alternatively, you can blend it in batches in a countertop blender. Please be cautious with the hot liquid.
- Stir in the heavy cream and adjust seasoning if needed. Let it heat through for another 2–3 minutes. Serve immediately with a fresh basil garnish and crusty bread for dipping.

Storage and Reheating Tips
This Roasted Tomato Basil Soup stores beautifully. Let it cool completely before transferring it to an airtight container. It will keep in the refrigerator for up to 4 days. The flavors often taste even better the next day.
For freezing, omit the cream and freeze the pureed soup base for up to 3 months. Add the cream when you reheat it. For more ideas, check out our guide on White Chicken Lasagna Soup. This prevents the dairy from separating and ensures a perfect texture every time.
Reheat gently on the stovetop over medium-low heat, stirring occasionally. Avoid boiling it after adding the cream. You can also reheat single portions in the microwave, covered, stirring every 30 seconds.

5 Common Mistakes to Avoid
Even the best recipes can go awry with a few simple missteps. Being aware of these pitfalls will guarantee your soup is a resounding success. For more ideas, check out our guide on Chinese Pepper Steak with Onions. Let’s navigate these potential hiccups together.
- Using Unripe Tomatoes: The flavor of your soup depends on sweet, ripe tomatoes. Avoid ones that are pale or hard. They lack the necessary sugar for proper caramelization.
- Crowding the Pan: If the tomatoes are piled on top of each other, they will steam instead of roast. Use two pans if needed to ensure a single layer. This is non-negotiable for flavor.
- Blending While Too Hot: When using a countertop blender, always allow the soup to cool slightly. Hot liquid can expand and blow the lid off, creating a dangerous and messy situation.
- Overcooking the Basil: Adding the basil at the simmering stage preserves its bright, fresh flavor. If you cook it for too long, it can become bitter and lose its vibrant color.
- Skipping the Cream: The cream or a dairy-free alternative adds a necessary richness and balances the tomatoes’ acidity. Don’t skip it if you want that classic, velvety texture.
Delicious Variations to Try
Once you’ve mastered the classic version, feel free to get creative. This recipe is wonderfully adaptable to different tastes and dietary preferences. Don’t be afraid to make it your own.
For a spicy kick, add a chopped jalapeño to the roasting pan. You can also stir in a tablespoon of harissa or sriracha during the blending stage. It adds a wonderful warmth that complements the sweet tomatoes.
To make it heartier, add a can of drained and rinsed cannellini beans before blending. For a protein boost, stir in shredded rotisserie chicken or cooked lentils at the end. For more ideas, check out our guide on high protein crispy garlic chicken fried rice. It transforms the soup into a complete meal.
If you’re vegan, use coconut milk instead of heavy cream. It provides a similar creamy texture with a subtle, lovely flavor. You can also add a tablespoon of nutritional yeast for a cheesy note.
Frequently Asked Questions
What type of tomatoes work best for Roasted Tomato Basil Soup?
Roma or plum tomatoes are ideal because they are meaty with less water and fewer seeds. This concentrated flesh leads to a richer, thicker soup. In a pinch, you can use vine-ripened or cherry tomatoes.
Can I make this soup without an immersion blender?
Absolutely. A standard countertop blender works perfectly. Just be sure to blend in small batches and leave the lid’s center piece removed to allow steam to escape. For more ideas, check out our guide on garlic shrimp tacos with avocado. Cover the opening with a towel instead.
How can I make my soup thicker?
If your soup is too thin, let it simmer uncovered for an extra 10-15 minutes to reduce. You can also add a tablespoon of tomato paste during the simmering stage. Both methods will effectively thicken the consistency.
Why is my soup tasting acidic?
Tomatoes can vary in acidity. A pinch of sugar or a grated carrot added during roasting can help balance this. The cream at the end also does a fantastic job of mellowing out any sharpness.
Can I use dried basil instead of fresh?
I strongly recommend fresh basil for its vibrant flavor. If you must use dried, add only 1-2 tablespoons when you add the broth. The flavor profile will be different, but it will still be tasty.
How long does it take to roast the tomatoes?
Roasting typically takes 35-45 minutes in a 400°F oven. You’re looking for the skins to be blistered and slightly blackened at the edges. This visual cue is your best indicator that they are ready.
Is this soup freezer-friendly?
Yes, it freezes exceptionally well. For best results, freeze the soup base before adding the cream. Thaw overnight in the refrigerator and add the cream when reheating gently on the stovetop.
