Few foods give the cozy comfort of a bowl of creamy vegan tomato soup with a toasted sandwich for dipping.
This full-bodied soup has a wonderful depth of flavor thanks to sun-dried tomatoes.
I didn’t grow up eating tomato soup. It wasn’t until I was in high school and over at a friend’s house that she introduced me to this simple, homey pleasure.
She’d take a can of condensed tomato soup, add a bit of milk to it, and heat it in a pot. While it was warming, she’d toast a couple of grilled cheese sandwiches.
Then we’d convene to the living room couches, dunking our sandwiches while we talked.
After that, grilled cheese & tomato soup was a staple whenever I wanted something effortlessly cozy.
Something about dipping that gooey sandwich into the soup made it better collectively than separately.
Grilled cheese and tomato soup doesn’t have to be a thing of the past, though.
This tomato soup recipe gives that old school favorite an upgrade.
Sun-dried tomatoes give it an extra depth of flavor, tomato paste amps up the richness.
And a spoonful of nutritional yeast & spices elevates the soup into a dish both children and adults alike can enjoy.
What kind of tomatoes should I use?
Fresh tomatoes may be perfect on a vegan BLT. But for a quick & easy soup, I recommend using canned tomatoes for this recipe.
Scoring, boiling, and blanching tomatoes to remove their skins before making soup is really fussy.
And who wants to be inside by a hot stove when you could have tomato soup in hand from start to finish in about thirty minutes?
I recommend using peeled whole tomatoes for this recipe.
While I love chopped fire-roasted tomatoes for things like vegan three bean chili, it can give too much of a burnt taste for a subtly sweet soup. So I prefer to opt for whole peeled San Marzano tomatoes.
Taste your canned tomatoes before using and make sure they don’t have a tinny taste, because if they do, that will stand out in a tomato soup where it’s all about the tomato flavor.
Even in canned tomatoes, tomato sweetness varies. So I’ve given a range of amounts of agave syrup for the soup.
If your tomatoes are very sweet, you may not need any at all. And if they are less sweet, feel free to add up to a couple teaspoons full.
That little bit of added sweetness also balances the acidity of the tomatoes.
Here are the ingredients you will need to make this recipe.
Oil: Any neutral-flavored cooking oil can be used to sauté onions and garlic. Avocado oil is my go-to.
Onion: Yellow onion is my preference, but any color will work.
Garlic: Freshly minced garlic has the best, most robust flavor. But it can be replaced with ⅛ teaspoon of garlic powder. If using powdered garlic, add it at the same time as the other seasonings.
Canned whole peeled tomatoes: You’ll need the juices as well as the tomatoes. San Marzano is my favorite.
Bouillon: Use a vegetable bouillon cube or 1 teaspoon Better Than Bouillon no chicken base.
Water + bouillon can be replaced with ½ cup of vegetable broth.
Seasonings: Dried oregano, dried basil, salt, and pepper.
Nutritional yeast flakes: This inactive yeast adds cheesiness and umami. Look for it in natural grocery stores or Trader Joe’s.
You can read more about it in this post, “What is nutritional yeast?“
Tomato paste: This adds a punch of tomato flavor. You can find it in jars or tubes in the center aisles of the grocery store.
Sun-dried tomatoes: This adds a wonderful depth of flavor. Look for the kind packed in oil.
Non-dairy milk: You can use any kind of non-dairy milk you enjoy, like cashew milk, almond milk, or soy milk.
Agave syrup: This optional ingredient adds a little sweetness, and offsets the acidity of canned tomatoes.
