Creamy Zucchini Soup (Instant Pot Recipe)

HOW TO MAKE INSTANT POT ZUCCHINI SOUP

This zucchini soup recipe is super easy! You only need a handful of ingredients and the dish comes together in under 30 minutes. Here is what you need for this cream of zucchini soup: 

  • Zucchini – we used about 1 kg/ 2lb of zucchini, also known as courgettes in the UK. Zucchini is available all year round and is often very affordable. It might seem like a lot of zucchini but it cooks down to soft and whizzes up into a silky, smooth, thick soup. The cream is there mostly for flavor!
  • Important: Zucchinis come in different sizes and shapes so make sure you use close to 1 kg/2 lb of zucchini for the amount of liquid in the recipe. If using a smaller amount, reduce water or you might end up with thinner soup consistency.
    Stock – you can use ready-made vegetable stock or water and stock cubes. Make sure the stock/water just barely covers the zucchini as the vegetable will give out a lot of moisture during cooking.
    Cream – you can add half and half, low-fat cream regular thickened cream or sour cream; yogurt would also work well here.

Zucchini soup ingredients

 

Step1. Dice the onions, garlic and zucchini; roughly is fine as the soup will be pureed at the end.

Step 2. Saute the onions in olive oil for 4-5 minutes on the Normal Saute setting, until softened. Stir a few times.

Step 3. Add zucchini, garlic, lemon zest, salt and pepper. Add water and crumbled stock cubes or ready-made vegetable stock. Stir through. The liquid should just barely cover the zucchini as the vegetable will give out a lot of moisture during cooking.

Step 4. Pressure Cook for 2 minutes on HIGH pressure. Pressurizing will take about 12 minutes, and then the 2-minute timer will begin. Once the timer is done, manually let off the remaining steam (quick release).

Step 5. Use an immersion stick blender to puree the soup directly in the Instant Pot or cool it off slightly and transfer it to a standing blender or a food processor in batches.

Step 6. Return pureed soup to the pot. Stir in the cream and lemon juice. Taste for salt and pepper and adjust seasoning if needed.

Ingredients

Scale

3 cloves garlic, diced

zest of 1/2 lemon

1 tbsp lemon juice

750 ml / 3 cups water

1.5 stock cube

1/2 tsp salt

1/4 tsp pepper

1/2 cup cream


Instructions

  1. Prep. Dice the onions, garlic and zucchini; roughly is fine as the soup will be pureed at the end. 
  2. Saute. Turn the Saute function on and once heated, add the olive oil and onions. Cook for 4-5 minutes on the Normal setting, until softened. Stir a few times. Press Cancel to stop the function.

  5. Once the timer is done, manually let off the remaining steam (quick release).
  6. Blend. Use an immersion stick blender to puree the soup directly in the Instant Pot or cool it off slightly and transfer it to a standing blender or a food processor in batches. 
  7. Finish with cream. Return pureed soup to the pot. Stir in the cream and lemon juice. Taste for salt and pepper and adjust seasoning if needed.

    1. Hi Karyn, all of our recipes are in a 6-quart unless specified otherwise. You should be able to use the same amount of liquid in the 8-quart one. Let us know how it goes 🙂

  1. Our instant pot arrived yesterday and this was the first recipe we tried in testing this new gadget. It was so incredibly easy and the result was super tasty. We’re on Keto so the poured cream at the end was a must. Great website. We’ll be using this as a regular reference.
