Quick Caramelised Onions

Quick Caramelised Onions

Believe the magic — make caramelised onions in the microwave! This recipe relies on a secret ingredient: baking soda. Cooking the onions with baking soda kickstarts the caramelisation process, no constant stirring or babysitting required.

All of Anyday’s recipes are tested (and retested!) in many different microwaves and home kitchens to make sure they work — and work well.

Select your microwave wattage in the dropdown. The cook times in this recipe will automatically change accordingly.

To find your microwave’s wattage, look at the front panel, the side of the door, in the back, in the user manual, or Google the model number. If both an input and output wattage are listed, use the output.

Wattage translates to how powerful the microwave is. The higher the wattage, the faster your food will cook. The lower the wattage, the longer the cook time.

When in doubt, start with less time — you can always add more.

Ingredients

  • 3 cups (300g) thinly sliced white onion
  • ½ teaspoon baking soda
  • 3 tablespoons butter
  • Sprig of fresh thyme (optional)

Preparation

  1. Toss onions, baking soda, butter, and thyme (if using) in the Anyday dish.
  2. Cook uncovered for 17 minutes or until the onions have turned a medium golden brown.
  3. Note that some liquid will bubble up. This is normal, and it is due to the release of juices during the cooking process. As the onion cooks down, the bubbling will stop.
  4. Enjoy caramelized onions warm, or store in an airtight container and refrigerate for up to 5 days.
