There's nothing quite as comforting as homemade tomato soup after a hard day's work, and this roasted tomato soup recipe is on another level!

🍅 Creamy Tomato Basil Soup
This is not your regular canned tomato soup that you can get in your local grocery store. This recipe is tried and tested to be the best roasted tomato soup you will ever try!
It's got everything you could possibly want in one bowl with a rich and creamy tomato, basil flavor, and just like the green pea soup, it's purified for an irresistible smooth consistency.
The recipe takes over an hour to cook as we let the ingredients infuse and simmer peacefully in a large stove pot.
Tomato basil soup is deliciously sweet with a slight tang coming from the balsamic vinegar and a pleasant creaminess from the sour cream blended with the roasted tomatoes until smooth.
It's what comfort food is all about, and when served alongside grilled cheese sandwiches, it's a match made in heaven!

Substitutions
Tomatoes
You can use fresh tomatoes if you can't find San Marzano tomatoes for this recipe, but I don't recommend using cherry tomatoes, as you need to roast them in the oven with garlic inside.
Cream
heavy cream or coconut cream works well in this recipe. Although, using coconut flavored cream will add a slight tropical feel to the soup. But still tasty nevertheless.
Spices
I like to add a touch of spice to my soups with half a teaspoon of red pepper flakes, cayenne pepper, or a chopped chili.

Prepare Ingredients
Step 1
Slice the onions into thin circles on the chopping board along with the carrots coarsely chopped, and set them aside.
Step 2
Make slices out of the garlic cloves for roasting inside the tomatoes.
Step 3
Grab the fresh basil leaves and tear them up into strips with your hands or coarsely chop them.
Cooking Instructions
Step 1
Preheat the oven to 400 degrees Fahrenheit (200 degrees Celsius).
Step 2
Line a baking sheet with aluminum foil and grease lightly.
Step 3
Drain the tomatoes, reserving the juice for later.
Step 4
Take each tomato and gently push about 2 or 3 slices of garlic in it, then arrange them apart on the foil drizzled with a little olive oil along with a sprinkle of dried basil, salt, and pepper.
Step 5
Roast in the top third of your oven for about 30 - 35 minutes, until beginning to char but not drying out completely.
Step 6
While the tomatoes are roasting, heat the oil and butter in a large soup pot over medium heat with the onions and carrot, adding a generous amount of salt and pepper. Sauté for about 5 or 6 minutes until the onion rings begin to lose their shape.
Step 7
Add the reserved tomato liquid, tomato paste, vinegar, sugar, and stock. Stirring occasionally until it starts to boil, and then reduce the heat to a simmer.
Step 8
Take the roasted tomatoes from the oven and add them to the pot with their juices. Continue to simmer for about 30 minutes to an hour.
Step 9
Remove the soup from heat, let it cool for about 10 minutes, then whisk a few tablespoons of the hot soup into the sour cream to warm it. Then pour creamy tomato mixture into the soup with the fresh basil and blend until smooth.
Step 10
Serve with a crusty baguette and garnish with a little sour cream on top with a few basil leaves.
Cooking Tips
The acidity in tomatoes can make the soup a bit bitter, but you counteract this with 2 spoons of sugar. Feel free to add another spoon if needed.
Make sure not to put the soup back on to the heat after adding the sour cream, or else it will curdle as it comes to a boil.
🥗 What to serve with
Roasted tomato soup pairs well with salads, fries, or sandwiches.
Sandwiches
Serving a grilled cheese sandwich with tomato soup is a common thing. I also like to add a bit of bacon with my cheese sandwiches to make a BLT and sometimes some spice with chipotle chile.
Fries
Perfect for dipping in soups and especially this rich tomato-flavored one! Make it healthy fries with my delicious avocado fries that are crispy and super easy to prepare.
Salad
An earthy arugula salad with olive oil, chopped walnuts, and parmesan cheese shavings is one of my go-to fresh salads to accompany soup recipes.
🙋 Frequently Asked Questions
