Roasted Tomato Leek Soup
Roasted Tomato Leek Soup, an easy homemade tomato soup with leeks, garlic and fresh basil. Simple vegan soup that's perfect for meal prep!
I was never a fan of tomato soup, honestly. I did not like the canned creamy and over-salted version that sat in our cupboard as a child (uneaten, not surprisingly).
It wasn't until I tried a taste of homemade tomato and basil soup at a friend's house a few years ago that I considered trying my hand at making my own.
And boy am I glad I did, because this Roasted Tomato Leek Soup is now famous in our house.
During tomato season in late summer and early fall this soup is a weekly occurrence. And when the market down the road puts one pound bags of tomatoes on sale for $0.99 you can believe that I'm coming home with bags full of tomatoes.
It's all I can do to find recipes to use them up, and this tomato soup is one of my favorites.
This recipe has evolved over time, as most recipes should. It started as a take on a classic tomato recipe and evolved into one with onions, garlic, basil and leeks.
No butter, no dairy, no cream. Just fresh vegetables and vegetables broth and a whole lot of flavor.
One thing that is absolutely not optional with this tomato soup is serving it with a side of bread. I'm particularly partial to sourdough since I live in San Francisco, but a fresh ciabatta or french baguette will also get the job done.
Because this tomato soup is for dipping, first and foremost.
How to make Roasted Tomato Leek Soup
First you'll start with about 3 pounds of fresh seasonal tomatoes. Cut them in half, drizzle them with olive oil, sprinkle with salt and pepper, and roast them in the oven for about 40 minutes or until they brown and release their juices.
In the mean time, cook the onions, garlic, and leeks in a soup pot. When they're softened, add your spices and broth. Then remove the tomatoes from the oven and add to the soup pot, bringing the whole mixture to a boil and then a slow simmer.
Before serving, add the basil and any salt and pepper to taste. Then blend with an immersion blender until smooth and serve with a side of sourdough. The BEST tomato soup!
Roasted Tomato Leek Soup: Tips, Tricks & Tools
This soup is as simple a soup recipe can be, but there are a few tricks and tools to make your time in the kitchen most efficient.
- A sturdy, ceramic soup pot. While I'm partial to my Lodge ceramic dutch oven, I have my eye on a larger soup pot because we like making extra to freeze and eat lunches all month.
- An immersion blender. I'm not one to collect needless kitchen gadgets (attempting to be a kitchen minimalist, plus my kitchen is about 100 square feet), but buying an immersion blender for soups changed my life. Before that I was scooping the soup into a blender, which was tedious and made a huge mess. The immersion blender was a game changer and took me from a soup amateur to master.
