Soup is such a great meal to make over the cooler months. For this Slow Cooker Vegetable Soup I've made the process even easier by cooking it in a slow cooker. You simply add the ingredients to the dish, then let it do all the cooking for you. Feel free to customise this with your favourite vegetables. You could even add some protein in the form of shredded chicken or bacon if you like.

Serve it with warm crusty bread and butter. If you have the time, why not try my No-Knead Loaf?

Ingredient notes:

A wooden surface displays two carrots, two celery stalks, three potatoes, an onion, two garlic cloves, a bowl of dried herbs, and a packet of vegetable soup mix.

Base vegetables: I used a combination of potatoes, carrot and celery. You could also use kumara, leek and parsnips or any other vegetables you want to use up.
Dried herbs: If you have fresh herbs available to you, feel free to use those instead!
King vegetable soup mix: This is a classic New Zealand and Australian packet soup mix. It contains lentils, grains and vegetable stock. You can substitute for your preferred soup mix easily.

Recipe FAQs:

Could I add meat to this?

Yes of course! Stir through shredded cooked chicken, ham or chopped bacon for a heartier option.

Is this soup healthy?

Extremely healthy! This soup is full of nutritious vegetables. During the winter months we all need a little help keeping the winter bugs away. Feeding your body with healthy fruit and vegetables can definitely help with that.

Storage:

Store your soup in an airtight container in the fridge for up to 5 days or the freezer for 3 months. Defrost completely (if frozen) then reheat until piping hot.

Top tips:

Add extra veg: This soup is super flexible, try adding kumara, pumpkin, parsnip or a handful of baby spinach at the end.
Make it meaty: Stir through shredded cooked chicken, ham or chopped bacon for a heartier option.
Soup mix swap: If you can't find King's soup mix, any dried soup mix with stock flavour lentils, barley or split peas will work.
