Miso Butter Poached Onions

Miso Butter Poached Onions

If you’ve never considered onions a side-dish worthy vegetable unto themselves, this recipe will make you change your mind. Onions are cooked in a buttery miso sauce until they’re fall-apart tender. If there’s a better side dish for chicken, we haven’t seen it!

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.
