Ingredients for Summer Zucchini Soup
Here are the handful of ingredients you need to make this summer squash soup.
- Zucchini - green
- Herbs- Dill or Cilantro or Parsley
- Scallions or Spring Onion or Chives or yellow onion
- Garlic Cloves
- Olive Oil
Zucchini
This is such a great way to use up all the fresh zucchini you get in summer. Look for dark green, blemish free zucchini when buying.
Though frankly, this recipe is quite forgiving. You can use your old forgotten zucchini in the back of the fridge too. You can also use frozen zucchini instead.
Herbs
Zucchini goes famously with basil and dill. That's usually my first choice but you can use any fresh herb you can find - including cilantro, mint and parsley
Thickener
If I am making this as a side and not a low carb meal, I usually skip using a thickener or just drizzle a bit of dairy or cashew cream on top.
But if I want this to be a hearty meal, I add cashews to the mix. This will give me a creamier soup plus it will keep me full for longer.
How to make Zucchini Soup in Instant Pot
Instant-Pot is a brand of Electric pressure cooker. I use a I use 6-quart instant pot model. This recipe will work in other brands and models too. You can also use traditional pressure cooker or make it on stover top.
To make it on stove top, increase the cooking time to 20 minutes and keep an eye on the water level.
Prep
Wash and Cut the zucchini into 1 inch pieces. It doesn't have to be uniform or pretty. Remember that we will be blending the whole thing into a soup. Roughly chop the fresh herbs and scallions too.
Pressure Cook
Add everything- zucchini, herbs, scallions, cashew(if using) and garlic to the instant pot along with 1 cup of water. Season with salt.
Select Pressure Cook on HIGH Pressure for 5 minutes
Puree
Once the 5 minutes of cook time is over and the instant pot beeps. Press cancel, you can Quick Release and open the pot.
Blend it to a smooth puree using the immersion blender.
IF you aren't able to get the smooth texture using an immersion blender, use a regular blender. If using regular blender, remember to cool the contents before pureeing.
Top with olive oil and creamy yogurt or cream.
Serving
I love a hot soup. In the colder months there is nothing more cozy and comforting than that. But sometimes, especially in peak summer, a cold soup just hits the right spots. And this summer soup can also be served cold like a zuppa.
When serving soup, you can add your favorite toppings for a visual treat and also textural balance.
Also here are some topping ideas
- Fresh Herb
- Greek Yogurt or Sour cream
- Heavy Cream
- Crispy Bacon
- Toasted Seeds & Nuts
- Grated Parmesan Cheese
- Smoked Paprika or cayenne pepper or red pepper flakes
Hot Tip
On busy weeknights, you could turn this soup into a main course by adding some cooked pasta to it.
Storing & Leftovers
Storing leftover zucchini soup in an airtight container is a great idea to enjoy it later. You should refrigerate the soup if you plan to consume it in the next 4-6 days.
For longer storage, place the containers in the freezer where is can be kept for up to 3 months.
Divide the soup into smaller portions based on your serving needs. This way, you can thaw and reheat only the amount you want to eat, reducing food waste.
When you're ready to enjoy the soup, thaw it in the refrigerator overnight if frozen. Then, gently reheat it on the stovetop or in the microwave until it reaches a safe and enjoyable temperature.
