Ingredients

- Zucchini - Buy firm, medium-size, green fresh zucchini for this soup. Small to medium size zucchini tastes better. However, if you have grown zucchini that you forgot to harvest on time, this recipe is perfect to use them as well.
- Broccoli - Buy organic broccoli whenever possible. Veggies from the brassica family, like broccoli, cabbage, cauliflower, etc, have common pest problems. Therefore, pesticides are widely used to control pest issues. Do not throw away broccoli stalks. Trim and peel them to use in the soup.
- Onion and celery - They add depth of flavor, create a nice soup base, and add nutrition to the dish.
- Garlic - Use fresh garlic cloves to flavor the soup. Avoid store-bought preserved chopped garlic as it lacks flavor.
- Seasonings - For this simple soup, just salt and pepper is enough. However, you can add thyme or parsley, paprika, etc., for more flavors.
- Liquid - Make the soup delicious by using chicken bone broth, stock, or veggie broth. Or add a mix of broth/stock and water.
Recipe variations
- Make creamy broccoli and zucchini soup - Add whole milk, whole cream, or coconut milk to the soup to make it rich and creamy. Adjust the quantity of broth or stock accordingly.
- Make cheesy soup - Add shredded cheddar cheese or your favorite cheese blend to the soup at the end of cooking. Kids will enjoy this version.
- Add more veggies - Consider adding more veggies like grated carrots, spinach, or kale to make the soup even more nutritious and to give it a deeper color.
- Protein-rich soup - Add cooked shredded or diced chicken pieces. Perfect to use leftover roasted chicken or Air fried whole chicken in this soup.
Prep tips
- Zucchini and celery - Wash, trim both ends and cut them into 1-2" pieces.
- Onion - Peel, trim ends, cut in quarters, and dice into 1-2" pieces.
- Broccoli - Cut the broccoli head from its stalk, then separate large florets. Trim the stalk ends and cut into 1-2" pieces. Trim the end of the stalk, peel and dice the same way.
- Garlic - There is no need to chop the garlic. Just peel it and use the whole clove.

How to make broccoli and zucchini soup?
Step 1: Sautéing garlic and onion
Heat some oil in a medium size pot. Add garlic cloves and onion and sauté until translucent.

Step 2: Cooking veggies
Add broccoli florets and zucchini to the sautéed onion and garlic. Add chicken broth (or use veggie option) and water. Season with salt and black pepper. Mix everything well and bring to boil. Cover and simmer the mixture for 15 minutes.


Step 3: Blending the soup
Turn off the heat. Using an immersion blender (or regular blender) blend the veggies until it gets to your desired consistency. Serve warm!


Step 4: Optional-Roast zucchini to garnish the soup
Dice some extra zucchini into small pieces and roast them in a frying pan with little oil until they turn medium dark brown. Use them to garnish the soup before serving. This will add a nice flavor to the soup. Serve crispy bread croutons with the zucchini soup for the crunch.

Instant Pot zucchini soup
Sauté garlic and onion with oil on sauté mode in the Instant Pot. Then add broccoli florets, diced zucchini, celery, and broth (or mixture with water). Season with salt and black pepper. Mix well and cook the soup on manual high pressure for 3 minutes. Quick release the steam, blend the soup and serve warm.
Serving suggestions

Helpful tips

- It is convenient to use an immersion blender if you have one to blend the cooked veggies with the liquid.

FAQs
Yes! You can use frozen broccoli to make the soup. If you have time, thaw before using them, although it is not necessary to.
Yes! You can freeze it in an air-tight container for a few weeks. However, I prefer to make it fresh using fresh veggies as this soup is very quick to prepare.
You can use yellow squash instead of zucchini. It has a slightly different taste. And it might change the color of the final soup.
