Roasted Tomato Basil Soup
This creamy roasted tomato basil soup is everything you want on a chilly night: rich, velvety, packed with deep roasted tomato flavor, and ready in under an hour with zero fuss.
Okay, real talk. My mom used to make tomato soup from a can and I thought that was just what tomato soup tasted like, kind of tangy and a little sad. Then I roasted my own tomatoes for the first time and honestly had a small kitchen epiphany right there at the stove.

Quick Overview: Why You’ll Love This Soup
This isn’t your average tomato soup. Roasting the tomatoes, onion, and garlic first brings out this deep, almost caramelized sweetness that canned soup could never dream of.
It’s a simple homemade tomato basil soup that comes together with one baking sheet and one pot, so cleanup is basically nonexistent. Blend it up, stir in cream and fresh basil, and you’ve got a creamy basil soup that tastes like it took way more effort than it did.
If you’re already a fan of cozy soups, this pairs perfectly with anything from our favorite soup recipes collection, especially if grilled cheese is involved (it should always be involved).

Step-by-Step Instructions
Roast the Vegetables
Preheat your oven to 400°F (200°C). Spread the halved tomatoes, quartered onion, and garlic cloves out on a large baking sheet.
Drizzle everything with the olive oil, then sprinkle generously with salt and pepper. Toss it all together right on the pan so every piece gets coated.
Slide the pan into the oven and roast for 30 to 40 minutes. You’ll know it’s ready when the tomatoes look soft and slightly blistered, and the garlic smells like something you want to bottle and wear as perfume.
Bring It All to a Simmer
Carefully transfer the roasted vegetables, juices and all, into a large pot or Dutch oven. Don’t skip the juices, that’s flavor gold sitting on the pan.
Pour in the vegetable broth and bring everything to a gentle simmer over medium heat. Let it bubble softly for a few minutes so the flavors start mingling.
Blend Until Silky Smooth
Grab an immersion blender and blend the soup right in the pot until it’s completely smooth. No immersion blender? No problem, just transfer the hot soup in batches to a regular blender.
Quick tip: never fill a blender all the way with hot liquid. Leave the lid slightly vented and cover it with a towel, or that soup will absolutely find a way to escape onto your ceiling.
Add the Cream and Basil
Stir in the heavy cream and freshly chopped basil, then taste and adjust the seasoning with more salt and pepper. If the soup tastes a little sharp or acidic, a small pinch of sugar smooths it right out.
Warm everything through for about 5 more minutes on low heat. Just don’t let it come to a full boil once the cream is in, or it can separate on you.
Serve It Up
Ladle the soup into bowls while it’s still steaming hot. Finish with a few extra basil leaves or a light swirl of cream on top for that cozy, restaurant-style look.
Expert Tips, Variations, and Troubleshooting
Tips for the Best Flavor
Let the tomatoes really caramelize in the oven, that’s where most of the flavor in this roasted tomato soup recipe actually comes from. If they look a little charred at the edges, that’s a good thing, not a mistake.
Fresh basil added at the end keeps its bright flavor and pretty color. Adding it too early in the cooking process can make it taste a bit dull.
Easy Variations to Try
Want it a little spicier? Toss in the optional red pepper flakes for a gentle kick. If you’re craving something with even more depth, our roasted red pepper soup is a fantastic next recipe to try.
For a dairy-free version, swap the heavy cream for full-fat coconut milk. It adds a subtle sweetness that pairs surprisingly well with the roasted tomatoes.
Troubleshooting Common Issues
Soup too thin? Simmer it uncovered for a few extra minutes to let some liquid evaporate. Soup too thick? Just stir in a splash more broth until it loosens up to your liking.
If your soup tastes flat, it usually just needs more salt, not more ingredients. Season a little at a time and taste as you go.
Storage, Reheating, and No-Waste Tips
| Method | How Long | Notes |
|---|---|---|
| Refrigerator | Up to 4 days | Store in an airtight container once fully cooled. |
| Freezer | Up to 2 months | Freeze in a sealed container, leaving room for expansion. |
| Reheating | 5 to 7 minutes | Warm gently on the stovetop over low heat, stirring often. |
To reheat from frozen, thaw the soup in the fridge overnight first for the smoothest texture. Reheating slowly on low prevents the cream from separating.
No-waste idea: save any leftover roasted vegetable scraps like onion ends or garlic skins for a homemade vegetable broth next time. Stale bread also makes fantastic croutons to float on top of this soup instead of tossing it out.
