Microwave Raw Onions: Soft or Crispy

Microwave Raw Onions Soft Crispy

You can microwave raw onions, so they are soft onions or crispy onions – and they take just a few minutes.  You might wish to cook them fully, or just to soften the onions to add to other recipes, such as making a microwave stuffing recipe from scratch.  This is a great way to cook a small quantity of onion without using a hob and pan.


  • 1 medium onion, chopped, sliced or cut into onion rings
  • 1 tablespoon of oil, or a mixture of oil and butter


  1. Place the onion, cut into slices, onion rings, or diced, in a microwave safe dish.
  2. Add oil and/or butter and ensure the onion pieces are coated fully.
  3. Cover the dish and microwave on full power (800 watts) for 2 minutes at a time, stirring after each 2 minutes to ensure more even cooking/browning, for up to about 8 minutes, depending on how dark and brown you want the onions to be.  It’s not until about 4 minutes have passed that you’ll start to notice the onions are cooking.


The oil to coat the onions is essential as it keeps the onions moist.  Stirring the onions is important to prevent it cooking unevenly;  stirring ensures the onions will cook evenly and brown more evenly.

Watch the onions while they cook if you want them to brown evenly – and microwave them in 1 minute blasts so you can stir them more often.

Using Cooked Onions: 

Here are some ways that I use onions that I’ve cooked in the microwave.

  • To add to egg fried rice, or to add to microwave chow mein.
  • When making a microwave stuffing recipe from scratch I’ll cook onions in the microwave until they’re soft (but not browned).
  • I’ll add crunchy onions into a cheese & potato pie sometimes to make it a little different.
  • Soften onion to add to a cheese and onion microwave omelette.
