RECIPE NOTES & TIPS

It's important to scrape the onions from the base of the Thermomix bowl in between the cooking times. This helps to ensure that they don't stick to the base.
While the soup is cooking, cook the cheese toastie slices - place thinly sliced baguette pieces onto a flat baking tray. Sprinkle the reserved gruyere cheese over the top and grill in the oven until golden and melted. Place on top of the bowls of soup when serving.
Do NOT exceed the MAX line - at no stage should you exceed the MAX line in the Thermomix machine. This is particularly important with the TM31 as the bowl is smaller than the TM5 and TM6. If you are close to the MAX line, use less chicken stock liquid.
MC OFF - for safety reasons, it's important to remove the measuring cup (MC) when cooking at very high temperatures. To avoid splatters, place the splatter guard or simmering basket over the top of the lid instead.
Store in an airtight container in the fridge for up to 3 days.
Reheat frozen soup in a pot on the stovetop or in the microwave.
Reheat defrosted soup in the microwave, on the stovetop or in the Thermomix.
The onion soup (without the baguette slices) can be frozen for up to 3 months, however, you'll need to make fresh cheesy toastie melts when you reheat the soup (see my tips below).
