Vegan Tomato Soup
BEST soup from scratch is Thick, Creamy, Cozy, Comforting but made without heavy cream or coconut milk (making it no dairy) yet so LUSCIOUS. This is a slightly modified version of our Instant Pot Tomato Soup.
Full of basil and a hint of garlic, this bisque will most likely be on you weekly rotation, no matter the season. I garnished with chopped cashews, torn basil and red pepper flakes for a hint of spice. Make ahead, serve immediately or freeze for later.
Cashews adds creaminess, thickness and makes it taste amazingly delicious!

WHAT IS THE DIFFERENCE BETWEEN TOMATO SOUP AND BISQUE?
Tomato Bisque is super silky smooth version, but made with shell fish stock (like crab or shrimp) and heavy cream. Whereas Tomato soup is made with fresh or canned tomatoes as the primary ingredient uses chicken or vegetable broth instead.
WHAT BLENDERS TO USE?
You can use a good quality immersion blender or regular blender like Vitamix (immersion blender takes a while and might get messy with soup splashing out if the pot isn't big enough). If using Vitamix or other blenders, make sure that bisque is cooled down to warm before blending.
WHAT TOMATOES TO USE?
This soup is excellent with canned whole peeled variety. So, it is excellent recipe to make in all seasons, even when fruits are not at their prime.
CAN I USE DRIED BASIL?
Sure can! Use about 1 tablespoon of dried basil instead of fresh. I suggest adding dried basil when you add the vegetable and cashews to give them a chance to soften.
WHAT POTS TO USE?
We'd recommend a non-reactive pot like stainless steel or enamel coated cast iron, for tomato based recipes. Avoid metal pots like cast iron or copper that can react with tomatoes and make the soup taste metallic.
INGREDIENTS
This recipe has only 5 main ingredients and few additional seasonings-
- Tomatoes - Whole peeled canned variety (preferably, San Marzano).
- Cashews - Whole raw cashews.
- Aromatics - Onion, garlic and Italian seasoning.
- Seasoning - Red pepper flakes, black pepper, sugar and salt.
- Basil - Fresh basil leaves
PRO TIPS FOR SUCCESS
- Blend until very smooth - Cashews might take a touch longer to blend well, so make sure to puree well for a silky smooth.
- We recommend a bigger pot if you are going to an immersion blender.
- Let the soup cool slightly before adding into a regular blender.
HOW TO GARNISH?
Soup can also be garnished with croutons, red pepper flakes, chopped basil, red pepper flakes or a swirl of coconut milk for a pretty finish.
HOW TO MAKE?
- Saute -Saute chopped onion and garlic in some olive oil, until onion turns golden.
- Simmer - Stir in canned veggie, raw cashews, red pepper flakes, Italian seasoning, salt, black pepper, sugar and water. Cover and cook in medium heat for about 20 minutes.
- Blend - Remove pan from heat, and blend everything until smooth (using an immersion blender or a high powered blender) and stir in chopped fresh basil, Serve.
HOW TO SERVE?
- Grilled cheese - Hot grilled cheese sandwich (keep it vegan by using vegan cheese slices) is always a classic.
- We sometimes like it with a good crusty bread on the side for dipping.
- Delicious as an appetizer for any Chicken, Shrimp, Fish or Vegetarian main course.
Other accompaniment suggestions: Garlic bread, Garlic knots, Stuffed mushrooms, Parmesan bread bites, Crusty bread or Avocado dinner rolls.
HOW TO STORE?
Store cooled bisque in air tight containers in the fridge for up to 4 days. Reheat in the microwave when required.
CAN THIS BE FROZEN?
Yes! It's perfect to make ahead and comes in handy for a busy weeknight. We like to freeze in single serve portions in quart size zip lock bags for up to 2 months. It thaws quick and perfect to serve one or two. Transfer to the fridge overnight to thaw.
Frequently asked questions:
Soup can be thickened using a variety of ingredients, like cornstarch mixed with water, blending stale bread along with the soup, ground nuts such as cashews or almonds, cooked vegetables such as carrot, cauliflower or potato or coconut milk.

Yes! Store in an airtight container in the fridge for 3 to 4 days or freeze up to two months.
You’ll need to make your own crushed ones which requires blanching and peeling. It can be a time-consuming process, so we find it much easier using canned variety.
Cashews are one of our families favorite snack. My husband can polish off an entire sheet tray of roasted cashews in a day! They are packed with plant based protein, fiber, heart healthy fats, antioxidants and so much more (refer more here).
