Frozen Vegetable Soup

If there is one type of vegetables that I recommend that you cook with it is frozen vegetables.

They have often had a bad reputation, but they are actually better for you than fresh vegetables (most of the time).

This is because when you buy fresh vegetables from the supermarket, they are sprayed with chemicals to make them long lasting. Yet frozen vegetables are frozen when at their best and have the best nutrients.

Plus, what I also love about frozen vegetables is that there is zero prep, and the frozen vegetables are often much cheaper.

Today I wanted to show you how to transform a boring bag of frozen mixed vegetables into a delicious creamy instant pot frozen vegetable soup.

You will just love how fast, easy, and tasty this frozen veggie soup really is!


Plus, as well as our free newsletter, we also have a free instant pot mini course. It is ideal for instant pot beginners or those that want to get more confident with their instant pot. The free course runs for 5 days with a new lesson delivered each day to your inbox.

Can You Put Frozen Vegetables In An Instant Pot?

Yes, you can. Cooking frozen vegetables in the instant pot is so easy, they taste just as good as fresh and there is zero prep involved.

We love to cook instant pot frozen vegetables a lot in the instant pot and today is all about a similar way and transforming those vegetables into soup.

Frozen Vegetable Soup Mix

This is the bag of frozen vegetable soup mix that I used:

Frozen Vegetable Soup Mix

We were living in Portugal when I made this instant pot frozen mixed vegetable soup and I used the bag above from the French supermarket that was down the road from where we lived.

It was a medley of vegetables and included carrots, cauliflower, peas, and a few other vegetables too.

You just need to find any bag of mixed frozen vegetables for this recipe. It can be what we used, it could be frozen cauliflower, broccoli, and peas, or even vegetables you have blanched and frozen yourself.

Or one of my readers loves Kroger vegetable soup mix.

Medley – Of course, it starts with your medley of frozen vegetables. Just like I have mentioned above, you can use any mix of frozen vegetables. You don’t even have to use one that says frozen soup mix on it. Or you could empty out a few different half used bags of frozen veggies that you have in the freezer.

Liquid – Its essential to have liquid to send the instant pot to pressure. Plus, you add more liquid compared to other instant pot recipes as you want a creamy soup. I recommend either tinned tomatoes, vegetable stock or seasoned water. By seasoned water I mean water you have mixed with your favourite herbs such as oregano or basil.

Seasoning – There is nothing worse than bland boring soup. I recommend oregano, thyme, basil, either one of these or all. Along with salt, pepper, and garlic. You can also add extra seasoning at the end if it doesn’t taste like it has enough flavour.

Then for the kitchen gadgets that we have used in this frozen vegetable soup in the instant pot, it has just been our instant pot pressure cooker. We have this one along with a hand blender. This was used to blend the soup and make it thick and creamy without having to move it to the blender and create more washing up.

How To Make Vegetable Soup In An Instant Pot?

  • Dump. Remember this is a ZERO PREP instant pot vegetable soup recipe. Simply dump into the instant pot ALL ingredients and place the lid on the instant pot pressure cooker.
  • Cook. Next you set the cook time to zero minutes and let the instant pot work its magic, whilst you plan your favourite sides.
  • Blend. Once the instant pot beeps and you do a quick pressure release, blend with a hand blender until smooth.
  • Serve. Serve with bread rolls and enjoy!

How Long To Cook Vegetable Soup In Instant Pot?

This easy vegetable soup with frozen vegetables takes ZERO minutes in the instant pot pressure cooker.

For those not familiar with instant pot zero minutes, it means the cook time is just the time to pressure. Then you do a quick pressure release, and you are ready to blend your soup.

You can also speed up these frozen veggies in the instant pot by adding warm or hot stock as this speeds up the time to pressure.

How Much Water Do I Put In My Instant Pot For Frozen Vegetables?

The water needed for vegetable soup with frozen vegetables is approximately 720ml which is the same as 3 cups.

This will create a yummy creamy soup that will be similar to a soup made with fresh vegetables and I bet your family will not be able to tell the difference.

What To Serve With Instant Pot Frozen Vegetable Soup?

Instant pot frozen veggie soup is just amazing served with some bread or bread rolls. In fact, my hubby always says, he will eat soup as long as there is bread!!!

I recommend you make our air fryer bread rolls. They are amazing and you can make them as a platter of pull apart bread rolls and they taste as good as they look.

Or put a loaf of our bread maker beer bread on for the ultimate bread making experience.

Or like our American readers like it, have our soup maker celery soup with air fryer grilled cheese.

Swaps. Speed things up and swap the thyme, basil and parsley for Italian seasoning.
Bland. I find that the frozen veggies need more seasoning than regular vegetables and when pressure cooked vegetables can lose their flavour. Therefore, do a taste test and add extra seasoning if necessary.
Hot. I recommend using a stock that is warm or hot. This will speed up the time to pressure and you are not waiting around for as long.

    1. Hi Ann,

      The only issue is that the red lentils are a thickener so the soup could end up too thick, and as we have not tested this recipe with lentils then we really cannot say how the soup will go, but here we have a soup recipe with red lentils in:

      You could change the butternut squash for frozen vegetables if you wanted if this recipe is of any help 🙂

    1. Hi Manjinder,

      We have not tried it on a stove top as the cooking times will not be correct, this recipe is just for any electric pressure cooker 🙂
