Have you ever trundled past the packaged soup aisle in the supermarket and spotted various bags of mixed beans, lentils and grains tucked amongst the brightly coloured packets of instant soup? In my supermarket, they are strategically positioned on the bottom shelf, hidden just well enough that only the truly dedicated can find them. Those mysterious bags are soup mix, and as I discovered recently, they are the express route to a hearty, filling and super easy vegetable soup.
Soup mix is not something I have previously used and if I am being completely honest, it wouldn’t have been high on my list of must-try’s had it not been for the packet that appeared in my monthly subscription box. I have to say that I am now a complete convert. Add some stock, a few vegetables and a good amount of seasoning, and you are well on the way to a substantial dinner. All that is needed is a loaf of crusty bread or some soda bread for a complete meal.
So what is soup mix?
Whilst there are many different brands and variations on the market, soup mix is essentially just a mix of lentils, peas, beans and grains that add bulk and fibre to a meal.
Soup mix does not require soaking before use, so can be added straight into your soup liquid. It will also bulk up a simple meat and vegetable stew, giving it a hearty edge. And as soup mix requires just that little more time in the pot to soften to eating consistency, it is ideal for adding to the slow cooker.
Ingredient Substitutions for Slow Cooker Vegetable Soup
If you can’t find soup mix, you can simply make your own. Try 1/3 cup split peas, 1/3 cup lentils and 1/3 cup barley for an easy mix.
To make the soup gluten free, either use a gluten free soup mix, or make your own soup mix using the ratios above, replacing the barley with quinoa.
Chicken stock can be used in place of the vegetable stock, although the soup will no longer be vegetarian or vegan.
This slow cooker vegetable soup is what I refer to as a fridge cleaner. I threw in the vegetables I had, so feel free to swap in whatever you have on hand. Try sweet potato or pumpkin, parsnip or celeriac. And kale can be used in place of the silverbeet or spinach.
Tips & Tricks for a delicious Slow Cooker Vegetable Soup
This recipe will make a lot of soup, so it is ideal for feeding a crowd or for stocking the freezer. The soup will thicken on standing, although adding a little extra water or stock when reheating will loosen it back up.
A ratio of 1 cup of soup mix to six cups of stock will produce a thick, hearty soup. Just add less soup mix if you want a thinner soup.Throw soup mix into the #slowcooker with a few chopped #vegetables and some #stock.

If you are short on time, don’t bother browning the onions and garlic. This is an additional step I like to take to maximise flavour in the slow cooker but is not necessary.
And if you are really short on time, cut up all the vegetables the night before. In the morning just toss all the ingredients into the slow cooker. Dinner will be done in less than five minutes.
Freeze any leftovers in meal sized portions for ready made lunches and dinners.
