Delectable Zucchini Soup combines onions, carrots, celery, potatoes, garlic, zucchini, and fresh thyme in vegetable broth with the perfect blend of spices. This easy soup is ready in about thirty minutes, making it easily doable on those busy weeknights when time is precious. It is chock full of nutrition, making it a wise family-friendly choice.
Sometimes we enjoy this soup by itself for a light late summer meal. For a heartier meal, I love to serve this tasty soup with Beer Bread with Cheddar and Arnold Palmer Drinks.

How to make Zucchini Soup
Start by heating a little oil in a Dutch oven or large pot over medium-high heat. Then add the onions, carrots, and celery, cooking until tender. Next, add the potatoes, garlic, celery salt, and cayenne pepper, cooking for a minute while stirring constantly. Then add the broth and bay leaves. Bring it to a low boil. Reduce the heat and simmer until the potatoes are almost tender. Then add the zucchini and cook for about 7-8 minutes or until it is tender. Finally, remove the bay leaves and stir in the fresh thyme or fresh dill.

Recipe notes and helpful tips
- All vegetable broth or all chicken broth can be substituted. For a vegetarian-friendly recipe, use all vegetable broth.
- Zucchini cooks fairly fast, so add it in the last 7-8 minutes so it does not overcook.
- Cayenne pepper adds just a bit of flavor with a little kick. If you prefer something more mild, substitute a little cumin, ginger, or coriander. Or try fresh herbs like parsley, dill, or thyme.
- For protein, add a can of drained and rinsed white beans, chickpeas, or cannellini beans.
- Don’t forget to remove the bay leaves. They have sharp edges and can pose a choking hazard.
- To make a creamy texture soup, cook until everything is extremely soft. Then remove the bay leaves and puree in a blender (don’t forget to remove the blender jar lid) or puree with an immersion blender. Work in batches and puree until smooth. Add a splash of heavy cream and a sprinkle of Parmesan cheese for added flavor with a hint of sweetness.
- Store in the refrigerator in an airtight container for up to 3 days. Or freeze in heavy-duty quart or gallon freezer bags for up to 3 months.

How to freeze this soup
To freeze, slightly undercook the potatoes and zucchini. Cool the soup completely and ladle it into heavy-duty quart or gallon-sized freezer bags. Be sure to mark the bags with the date and the contents. Lay them down in a single layer on cookie sheets in the freezer. Once fully frozen, stack the bags in the freezer to save on space. Remember to thaw in the fridge overnight. Reheat on the stove top on low or in the microwave at reduced power so as not to overcook any ingredients.

LUV this soup recipe! Will definately add to the rotation during the winter months. Only deviation from the recipe was I didn’t add cayane pepper but added lots of black pepper and also added some Tarragon and dried Thyme (no fresh available). It is really yummy… even for those who don’t love vegtable soup!
Beth Pierce
So glad that you liked it! Tarragon and thyme sound delicious!
Michele
This soup is AMAZING! I used ALL homegrown veggies from my son’s garden! Homegrown celery is the best! I made 4 batches about to make 2 more!
I was wondering can I add beetroots & sweet potatoes? They are homegrown and I don’t want to waste them. THIS SOUP IS ABSOLUTELY AMAZING as written in original recipe so I’m extremely skeptical to change it. Also, I know roasted beets would change the color of the broth.
PLEASE I need a response. Thank you.
Beth Pierce
I have never tried that but it sounds delicious. Please let us know the results so I can post it.
