Creamy Roasted Tomato Basil Soup That Feels Like Home
There’s something deeply soothing about a warm bowl of Roasted Tomato Basil Soup. It’s one of those timeless recipes that never fail to comfort—simple ingredients, classic flavors, and that unbeatable aroma of roasted tomatoes wafting through your kitchen. This soup isn’t just food; it’s nostalgia in liquid form. Whether you’re dipping a grilled cheese sandwich into it or savoring it on its own, it’s a dish that embodies coziness and warmth.
What makes this version special is the dual layering of tomato flavor—first from the oven-roasted Roma tomatoes, and then from the luscious San Marzano tomatoes simmered with butter, garlic, and onions. The result is a silky, tangy, and slightly sweet soup with a deep roasted undertone that canned soup could never match. The fresh basil adds brightness, while the touch of cream smooths everything into velvety perfection.
I fell in love with this recipe years ago after visiting a small Italian café that served roasted tomato soup with rustic bread and a drizzle of olive oil. Since then, I’ve tweaked and tested it countless times to get the balance just right—bold but not acidic, creamy but not heavy, and packed with real tomato flavor.

Roasted Tomato Basil Soup
Ingredients
Method
- Roast the Tomatoes:
- Preheat your oven to 400°F (200°C). Arrange the sliced Roma tomatoes on a baking sheet, drizzle with olive oil, and sprinkle lightly with salt and pepper. Roast for 25–30 minutes, until caramelized and slightly shriveled.
- Sauté Aromatics:
- In a large pot, melt the butter over medium heat. Add the diced onion and cook for 5–6 minutes until translucent. Stir in the garlic and thyme, cooking for another minute until fragrant.
- Add Roasted and Canned Tomatoes:
- Add the roasted Roma tomatoes to the pot, followed by the crushed San Marzano tomatoes. Stir to combine and let simmer for 10 minutes to allow the flavors to meld.
- Season and Simmer:
- Add the sugar, salt, black pepper, and chicken stock. Bring to a gentle simmer and cook uncovered for 20 minutes, stirring occasionally.
- Blend the Soup:
- Using an immersion blender (or carefully transferring to a regular blender), puree until smooth and creamy. Return the soup to the pot if needed.
- Finish with Basil and Cream:
- Stir in the chopped basil and heavy cream. Simmer for another 2–3 minutes until warmed through.
- Taste and Serve:
- Adjust seasoning if needed and serve hot with a drizzle of olive oil or a sprinkle of parmesan.
Notes
- Active Time: 25 minutes
- Passive Time: 35 minutes
- Roasting the tomatoes enhances sweetness and depth—don’t skip it!
- For a vegan version, substitute butter and cream with olive oil and coconut milk.
- Use San Marzano tomatoes for the richest flavor.
Elevating the Flavor of Your Roasted Tomato Basil Soup
Roasting the Tomatoes to Perfection
Roasting is the heart of this recipe. It concentrates the natural sugars in Roma tomatoes, turning them slightly caramelized and jammy. Spread them cut side up, drizzle generously with olive oil, and roast until the edges darken slightly—those charred bits add smoky flavor that’s pure magic.
Choosing the Right Tomatoes for Balance
Roma tomatoes work beautifully, but if you want a bolder, deeper flavor, try heirloom or plum tomatoes. Avoid watery varieties like beefsteak—they dilute the soup’s body. A mix of fresh and canned tomatoes creates that full, layered tomato taste.
Enhancing Depth with Butter and Thyme
Butter and thyme may seem simple, but together they create a silky, aromatic base. Butter mellows the acidity of the tomatoes, while thyme infuses subtle earthy tones. I also sometimes add a splash of balsamic vinegar for a gentle tang.
Blending Techniques for the Silkiest Texture
An immersion blender gives a rustic texture, while a high-speed blender creates a restaurant-smooth finish. Blend in batches if needed, and for an ultra-luxe version, strain through a fine mesh sieve after blending.
Adding Cream at Just the Right Moment
Add heavy cream at the end, after blending and lowering the heat. This prevents curdling and ensures a glossy, velvety consistency. A swirl of cream right before serving also makes for a beautiful presentation.
Keeping Roasted Tomato Basil Soup Fresh and Flavorful
Storing Leftovers Like a Pro
Store leftover soup in airtight containers in the fridge for up to 5 days. The flavors deepen beautifully overnight, making it even better the next day.
Freezing Without Losing the Creaminess
If you plan to freeze, skip the cream initially. Freeze the soup base in portions, then add the cream after reheating. It keeps the texture smooth and the flavor fresh.
Reheating Gently for Perfect Consistency
Reheat on low to medium heat to avoid separating the cream. Stir frequently, and add a splash of stock or water if it thickens too much.
Refreshing Leftovers with Fresh Basil
Before serving reheated soup, toss in a few fresh basil leaves or a drizzle of olive oil. It instantly revives the aroma and adds a pop of color.
Pairing and Serving Ideas
Serve with crusty sourdough, parmesan crisps, or even a classic grilled cheese sandwich. The soup’s creamy acidity pairs beautifully with anything buttery and crunchy.
Making Roasted Tomato Basil Soup Work for Every Diet
Veganizing Without Losing Creaminess
Substitute butter with olive oil and heavy cream with coconut milk or cashew cream. The soup remains rich and silky with a subtle nutty twist.
Creating a Dairy-Free but Luxurious Version
Use a mix of oat milk and olive oil for creaminess. It adds mild sweetness while staying completely dairy-free.
Gluten-Free and Naturally Simple
This soup is naturally gluten-free—just check your broth labels. Pair with gluten-free croutons or a slice of gluten-free bread for dipping.
Lower-Calorie Adaptation Without Sacrificing Flavor
Skip the butter and reduce the cream to ¼ cup, or use milk instead. Roasting still keeps the flavor deep and satisfying.
Keto-Friendly Adjustments
To make it keto, reduce or skip sugar and use bone broth instead of chicken stock. The high-fat cream base fits perfectly into a keto plan.
Your Most-Asked Roasted Tomato Basil Soup Questions
Can I Use Canned Tomatoes Only?
Yes! You can skip roasting and use two cans of San Marzano tomatoes instead. However, roasting fresh tomatoes adds that caramelized sweetness that truly elevates the flavor.
What’s the Best Way to Make It Thicker?
Simmer longer to reduce liquid or add a spoonful of tomato paste. You can also blend in a roasted red pepper for natural thickness and color.
Can I Make It Ahead of Time?
Definitely. It tastes even better the next day as the flavors meld. Store in the fridge overnight and reheat gently before serving.
Can I Serve This Soup Cold?
While it’s meant to be served warm, this soup can double as a chilled summer soup (similar to gazpacho). Serve with a drizzle of olive oil and fresh basil for a refreshing twist.
What Protein Can I Add to Make It a Meal?
For extra substance, add grilled shrimp, shredded chicken, or even white beans. They soak up the tomato-basil flavor beautifully and make it a hearty main course.
