Culinary school not only taught me technique, but also exposed me to new foods. Or in the case of this vegan eggplant soup, new ways of preparing foods that I was absolutely certain I didn't like.
I learned that eggplant, when combined with tomatoes, is nothing short of delicious. It adds depth and additional umami to the tomato. And the tomato adds body and pizzazz to the eggplant.
For some great examples of this flavor combination, check out these other eggplant recipes:
- Eggplant Parmesan Casserole made with pesto,
- Sicilian Pasta, and
- Moroccan Chickpea Stew that I modified from one of my many Ottolenghi cookbooks.
๐ Is eggplant bad for you?
For some people, the answer is yes. Eggplant is part of the nightshade family, along with tomatoes, potatoes, bell peppers and tomatillos.
Nightshades contain alkaloids, including solanine, which can be toxic. While bad effects of eating nightshades have not been proven, if you suffer from an auto-immune condition, ask your physician if you can ingest nightshades.
๐ Is eggplant good for you?
But eggplant have a lot of nutritional benefits, as well. So if you're not sensitive to vegetables in the nightshade family, they can be good for you. For example:
- Eggplant provides a beneficial amount of fiber, vitamins and minerals while only containing a few calories.
- They are high in antioxidants.
- Its fiber content supports digestive health.
๐ง Main Ingredients + Notes
The secret to faster and easier meals often lies in the ingredients. For example, store-bought items and ingredients you make ahead and store in the refrigerator (or freezer) can turn a 60-minute recipe into a 30-minutes meal or less.
For the all of the ingredients, measurements and directions for this eggplant soup recipe, go to the Recipe Card at the bottom of this post.
- Eggplant - either globe and Italian eggplant work great in this soup.
- Tomato - any kind of medium sized tomato is perfect.
- Onion - I prefer yellow onion, but white onion is also fine. Steer away from red onions when making this vegan eggplant soup.
- Garlic
- Fresh herbs - I use a combination of oregano and thyme from my garden. Marjoram works great too.
- Spices - cumin and a dash of cayenne pepper.
- Vegetable Broth or Vegetable Stock- I useย Better Than Bouillonย vegan pastes. To use these pastes, measure 1 teaspoon of bouillon for every cup of water added to the soup. NOTE: If you use a sodium-free broth in this vegan eggplant soup, you may need to add additional salt at the end.
- Balsamic vinegar - this is a great way to add a little extra savory umami oomph. The amount is small so feel free to use whatever balsamic vinegar you have on hand.

๐ How to roast and peel eggplant
This eggplant soup is very easy to make, but if eggplant is a vegetable you've not worked with before, here's the best way to roast and peel it, and then remove the seeds, along with tips.
How to roast eggplant
Either roast the eggplant whole on a baking sheet in a preheated 400หF oven, or slice each eggplant in half lengthwise, and roast them with their cut sides facing down on a baking sheet.
Slicing them in half reduces the roasting time, but the eggplant surface resting on the baking sheet becomes dry and tough. Slice it off after the roasting is complete.
How do you know when eggplant roasting is complete?
The eggplant are done roasting when the skin darkens and becomes all wrinkly. The eggplant skin will feel hollow to the touch, and easily press in on the meat inside. The meat of the eggplant will feel soft when the skin is pressed in.
How to peel eggplant and remove the seeds
Step 1. When the eggplant are cool enough to handle, slice off the top of each, and and cut in half, lengthwise. A chef's knife is ideal for this.
Step 2. Starting at the bottom rounded edge where it's easiest to separate the skin from the meat, slip the point of a knife between the skin and flesh, and tease the skin away.
A paring knife works very well for this, or a curved Bird's Beak Knife if you have one.
Step 3. Discard the skins.
Step 4. Nudge the ropes of seeds away from the meat of the eggplant using both your fingers and a paring knife. Be sure to pull the eggplant completely open to get at all the ropes. Many of the strands of seeds hide in layers of the meat.
Don't be concerned if stray seeds remain. It's unavoidable.
Take the remaining meat and coarsely chop.
๐ง Best Way to Store Roasted Eggplant Soup
- Store leftovers in the refrigerator:ย Allow the soup to completely cool to room temperature, and place in an airtight container. Refrigerate for up to 4 - 5 days.
- To freeze:ย Allow the soup to completely cool to room temperature, and place in an airtight, freezer-safe container. Store in the freezer for up to one month.
