How to make roasted tomatoes basil soup
Arrange chopped ingredients in one layer on a baking tray. Drizzle olive oil. Season with salt and ground pepper.
Don’t bother chopping the ingredients fine. Roughly chop tomatoes, white onions and celery.
Roast in oven at 400 F for about 30 to 45 minutes. Time taken to roast entirely depends on the size of tomatoes you chop and the quantity of ingredients on the tray.
Do not over load the baking tray with ingredients and make sure they are in one single layer for even roasting.
Blitz the roasted ingredients. You can go as smooth or keep is chunky coarse depending on how you like to have your soup.
Add fresh basil leaves and blitz again. The amount of basil leaves in the soup is totally up to you. I love basil but too much basil is not my thing.
I find over powered basil flavor to be unpleasant. Go with your taste buds preference and add as much basil as you like.
We served the soup with grilled garlic bread and grilled cheese bread (for the kids).
FAQS

Notes
- I roasted all ingredients together at a time in oven. Alternatively you can roast just tomatoes, garlic in oven and roast onions separately on stove top or if you have left-over caramelized onions stored. This method will give you perfectly caramelized onions to make rich soup.
- I don’t usually strain my soup, as I don’t mind it chunky. Feel free to run the soup through a fine mesh strainer, you’ll have perfectly smooth tomato soup.

We love soups and it has only been recently whereby I’m enjoying the wonderful flavor of homemade tomato soup or should I say roasted tomato soup. That awful canned variety ruined it for many people. For years I wouldn’t try it and when I discovered that homemade was simply delicious — well, now I crave it. Your recipe is just the way I like it.
Noel Lizotte says
Two of the best flavors combined. I’ve got basil coming out my ears with the garden this year… one wouldn’t think a single plant would produce so many leaves! I’ll be saving this recipe for when the tomatoes come in …
Veena Azmanov says
Oh, such a pretty color on this soup. Soon we will start making soup again on a regular basis. Tomato and basil sound like the perfect combination for a good tomato soup. Saving this for later. Looks yum.
Gloria says
