Creamy Roasted Tomato Basil Soup Recipe
You’re about to discover my absolute favorite way to transform humble Roma tomatoes into the most luxurious soup you’ll ever taste. I’ve spent years perfecting this creamy roasted tomato basil recipe, and I’m thrilled to share the secret technique that brings out their natural sweetness. When those tomatoes caramelize in the oven, they create an incredible depth of flavor that canned varieties simply can’t match. Let me show you how to make this restaurant-worthy soup in your own kitchen.

The Secret to Perfect Roasted Tomatoes
While roasting tomatoes might seem straightforward, I’ve discovered that achieving that perfect caramelized sweetness requires a few insider tricks.
You’ll want to drizzle olive oil generously over halved Roma tomatoes, then sprinkle with sea salt and a pinch of sugar.
I’ve found that roasting at 400°F for 45 minutes, cut-side up, gives you that concentrated, jammy sweetness that makes soup incredible.
Essential Ingredients and Equipment
Success in making this classic soup starts with gathering the right tools and quality ingredients. You’ll need a heavy-bottomed Dutch oven, baking sheets, and an immersion blender. For ingredients, gather 3 pounds ripe Roma tomatoes, 2 cups vegetable stock, 1 cup heavy cream, fresh basil, 4 garlic cloves, yellow onion, olive oil, salt, and pepper. I always keep extra basil on hand for garnish.
Step-by-Step Cooking Instructions
Three simple steps kick off this cozy soup – preheating your oven to 400°F, halving the tomatoes lengthwise, and arranging them cut-side up on your baking sheets.
Drizzle them with olive oil, sprinkle with salt and pepper, then roast for 45 minutes until caramelized.
While they’re roasting, sauté onions and garlic in butter until softened.
Finally, blend everything with fresh basil and cream until silky smooth.
Flavor Variations and Add-ins
Although this classic tomato basil soup is delicious on its own, I’ve discovered some amazing ways to customize the flavors and make it truly your own.
Try adding a splash of heavy cream, crumbled goat cheese, or a dollop of pesto for richness. You can also spice things up with red pepper flakes, smoked paprika, or roasted garlic.
My personal favorite is stirring in caramelized onions and a dash of balsamic vinegar.
Storage and Reheating Tips
Since this homemade tomato basil soup keeps beautifully, I’m excited to share my tried-and-true storage methods with you.
Store leftover soup in an airtight container in your fridge for up to 4 days. For longer storage, freeze portions in freezer-safe containers for up to 3 months.
When reheating, warm gently over medium-low heat, stirring occasionally to maintain that silky texture.
Serving Suggestions and Pairings
While this cozy tomato basil soup is delicious on its own, I love serving it with crispy grilled cheese sandwiches for the ultimate comfort food experience.
You’ll also enjoy pairing it with garlic bread, crusty sourdough, or homemade croutons. For a lighter meal, try adding a fresh green salad dressed with balsamic vinaigrette.
I sometimes top mine with a swirl of cream and extra basil leaves.
Recipe Notes and Expert Tips
Before diving into the recipe, I’ve discovered a few game-changing tips that’ll help you make the most incredible tomato basil soup.
First, use vine-ripened tomatoes and roast them until they’re deeply caramelized.
If your soup’s too acidic, add a pinch of baking soda.
For extra creaminess, blend in a peeled potato – it’s my secret weapon!
And always taste for seasoning before serving.
