Why You Will Love It
- Easy - This slow cooker soup couldn't be easier. You just chop all the vegetables up and put them in the slow cooker with the stock. No need to keep an eye on it or stir. Just leave it and get on with your day.
- Adaptable - There are so many different vegetables you can put in this and it's a great fridge clear out as it doesn't matter if the vegetables are past their best.
- Budget friendly - This is a really cheap recipe to make. You can bulk it out with root vegetables and batch cook it too. Not to mention slow cookers are much cheaper to use than cooking this on the hob.
- Comforting - hearty comfort food, but nutritious too.
- Nutritious - This is a veggie packed soup meaning it is super nutritious and bursting with vitamins.
- Virtually fat free - Cooking this vegetable soup in the slow cooker means that you don't have to use any oil to brown and soften the vegetables first. Meaning that this is virtually fat free if you leave the cream out. However, your body can't absorb vitamin A without a little fat, which is why we like to drizzle some cream or olive oil on top. But the butter on the homemade bread counts too!
Ingredients and Substitutions
A full ingredients list, along with US Customary and Metric measurements, can be found in the recipe card at the end of this post.
- Butternut Squash - This has so much sweetness and colour, as well as making this slow cooker soup really filling. You can use any squash though.
- Carrots - This adds flavour and colour. We have used basic supermarket carrots to make this a really budget friendly meal.
- Parsnips - These are lovely and creamy and with an almost liquorice flavour. So good to add to hearty winter soups.
- Potato - This helps to thicken the soup and make it a little bit creamy. For a more vibrant colour, use sweet potato.
- Onion - This is the base of the soup. You could swap it for shallots, which would give a sweeter taste or even leeks.
- Garlic - Freshly crushed is best, but you could save time by using ready crushed garlic.
- Celery - This is always a base to our soups and adds a lovely depth of flavour.
- Vegetable stock - Always use homemade stock if you can. If not, use the best quality stock you can buy. We used vegetable stock to keep this soup vegetarian. If making this for young kids, then use a low salt stock. You can use chicken stock for a richer flavour though.
- Salt and pepper - Generously season.
- Single cream (optional) - This adds a lovely extra creaminess to the finished homemade vegetable soup, but it is optional. Leaving it out makes this vegan and virtually fat free.
Variations
The great thing about this slow cooker vegetable soup is that it is so easy to adapt. This recipe is made up with whatever I had leftover in the fridge, and what I knew my kids would enjoy.
I wanted it to be a nice golden colour, rather than a super green colour too as I knew that would make it easier to get my kids to eat it. However, here are some other vegetables to would go well in this soup:
- Broccoli
- Bell pepper
- Cabbage
- Spinach
- Peas (these are nice stirred into the blended soup for a bit of texture)
- Green beans
- Sweet potato
- Asparagus
- Butternut squash
- Courgette
If you want to add some extra flavour to this slow cooker soup, then why not add some curry powder or curry paste? It would give it a nice little kick.
You could also stir in some fresh herbs just before serving - fresh basil or parsley are my favourite with soup.
To make this slow cooker veg soup more filling, you have a few options. You could add a can of cooked lentils which would give it a protein boost, or even some cooked chickpeas.
For a filling, but child-friendly option, you could stir in some cooked pasta. Something little like macaroni would work.
How to Make Slow Cooker Vegetable Soup
- Step 1: Finely dice all your vegetables and add them to the slow cooker.
- Step 2: Pour in the stock and give everything a good stir.
- Step 3: Cook on high for 4 hours.
- Step 4: Use a stick blender to blend the soup to your desired consistency.
- Step 5 (optional): Stir in some single cream, if using.
Serving Suggestions
A couple of slices of buttered crusty bread go down well. We served this homemade vegetable soup with our Slow Cooker Bread. But, why not do something a little different and serve with some some warm pita bread or even our Easy Homemade Flatbreads? You could also try our Garlic and Rosemary Focaccia.
Soup and bread is such a classic combination. But why not take the humble slice of bread and butter up a gear and make your own crunchy croutons Not just any croutons, but cheesy, herby croutons. They are so easy to make, and a great way to use up bread that is going a little stale.
Just take a couple of slices of bread and cut into 1 inch cubes and scatter on a baking tray. Drizzle with olive oil and sprinkle with Parmesan (or grated cheddar) and sprinkle with dried oregano. Put them in a preheated oven at 180°C/350°F/Gas 4 for around 8 minutes.
Or you could try our Air Fryer Croutons or our Sourdough Croutons recipe.
Storage
Store: This slow cooker vegetable soup can be kept in an airtight container in the fridge 3-4 days.
Freeze: If you want to freeze the soup, put it in an airtight container, leaving a gap of about 1cm (0.5 inch). This will keep in the freezer for 2-3 months.
Defrost: Defrost in the fridge overnight before reheating. If you used cream, you will need to use a whisk to gently stir the liquid in the soup. Because it has dairy in it, it needs to be moved around a lot to get that creamy texture back.
Reheat: Reheat on the hob (stove top) until cooked through, about 5 minutes.
Dannii's Top Tips
- Cut all the vegetables evenly, into small pieces so that they will cook quickly. Big chunky bits of vegetables will take much longer to cook, especially the root vegetables.
- You don't have to peel the carrots and potatoes. It will save time and add fibre.
- Spice this soup up a little with a sprinkling of red chilli flakes before serving or even adding some curry powder at the same time as the vegetables.
- If you are making this soup for young children, then use a low salt stock.
- If blending this in a jug blender, allow to mostly cool first, so the heat doesn't crack the blender.
- You can make this more of a filling soup by stirring in a can of chickpeas.
- A little bit of grated cheddar, crumbled stilton or Parmesan shavings on top finishes this perfectly.
Frequently Asked Questions
Yes, you can use frozen vegetables for this recipe, however that tends to give you a much more watery soup. If you are using frozen vegetables, then you will need to reduce the amount of stock you have used. Using frozen vegetables means you can make this soup any time, and makes it much more budget friendly too.
No, if you prefer a chunky soup, then you don't need to blend it at all. It would be more like a broth though.
You need to make sure all the vegetables are finely diced, and evenly cut otherwise they won't be cooked in the 4 hours cooking time if the chunks are too large.
All slow cookers cook things differently, so if yours is too thick, then just add a little more vegetable stock to thin it out.
