Believe the magic — make caramelized onions in the microwave! This recipe relies on a secret ingredient: baking soda. Cooking the onions with baking soda kickstarts the caramelization 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.

3 cups (300g) thinly sliced white onion
½ teaspoon baking soda
3 tablespoons butter
Sprig of fresh thyme (optional)
Toss onions, baking soda, butter, and thyme (if using) in the Anyday Deep dish.
Cook uncovered for 17-18 minutesor until the onions have turned a medium golden brown. Check halfway through cook time to make sure the onions are cooking properly.
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.
Enjoy caramelized onions warm, or store in an airtight container and refrigerate for up to 5 days.
Serving suggestions & tips
This recipe can be made vegan by substituting olive oil for butter.
Top a burger or hot dog for a quick, pub-inspired dinner.
Finely chop caramelized onions and add them to mac and cheese for an extra flavorful dish.
Note: It is important to use a Deep Dish for this recipe! A Shallow Dish will spread out the onions and liquid, forcing it to evaporate too quickly in the microwave. Too little liquid can result in scorched onions!
Microwave ovens vary, even with the same wattages. Adjust cooking times as needed.
