Soups are a great way to pack in a load of speed foods for a Syn free lunch.

You can also make this in a slow cooker, but you’d need to brown the onions in a frying pan first.

This soup is really simple to make, with no blending or blitzing required.
You will need an Instant Pot
The Instant Pot is like a slow cooker/pressure cooker hybrid and is probably one of our favourite kitchen gadgets.
You can cook stews and soups in it in a quarter of the time it would take in a slow cooker! This Syn Free French Onion Soup takes 5 minutes in the Instant Pot, but would take about 2 hours in a slow cooker!
How many Syns are in this Syn Free French Onion Soup?
As the title suggests, this Syn Free French Onion Soup is…Syn Free! In fact it is packed full of Speed Food!
There are a few things you can use to garnish this soup. We like to toast a slice of Healthy Extra B bread, topped with some Healthy Extra A Reduced Fat Emmental.
Whatever you choose don’t forget to check the Syn value and adjust it accordingly.
How do I make this Syn Free French Onion Soup?
Slice the onions and garlic finely. Set the Instant Pot to Sauté, spray the inner with Frylight and brown the onions and garlic.
Do not stir too frequently, you want the bottom to brown to give the soup extra colour.
Add the balsamic vinegar and Worcestershire Sauce and stir. Pour in all of the water and add the beef stock cubes and vegetable stock pot. Press the “off” button.
Put the lid on, ensure the pressure valve is closed, and press the “Manual” button. The Instant Pot may take a little while to come up to pressure as there is quite a lot of liquid in there!
Once the Instant Pot has beeped to let you know it has finished, quick release the pressure (careful not to get in the way of the releasing steam!). Serve the soup with a garnish of your choice!
Whenever we need to replace oil in cooking we use Frylight. Perfect for everyday frying and cooking, it delivers exactly one calorie per spray, which makes it Syn free! We used the Olive Oil one for this Syn Free French Onion Soup recipe, and it was fab!
