What’s the difference between caramelized onions and sautéed onions?

The cooking process and the quantity used are the ultimate difference between the two.

To sauté onions, we tend to use less quantity and less cook time. These types of onions made are great with other added vegetables or to use on top of other dishes.

Caramelizing is a slower and longer cooking process of sautéing onions.

When sautéing onions, they turn to a golden colour, but the edges turn lightly browned while caramelizing can turn onions into a darker brown and softer.

  4. Stir well then close it with a lid and let it cook for a minute or two.

  5. Remove the lid. Stir & sauté further for another 20 more minutes without the lids this time.

  6. NOTE – Remember to stir the onions every few minutes to avoid it from burning. If the ingredients look too dry, burning and/or smoking up, remember to lower the heat and add a spoon of cooking oil or as need.

  7. When the onions are coming together cooked and looks glossy, add the sliced green chili pepper and the Maldives fish (both optional). Continue cooking for another 5-10 more minutes.

Onion Sambal Recipe Notes

  • You can accelerate the cooking process by not using a lid, increasing the heat level between medium/higher. This may create more steam/smoke. Constantly stir to avoid food burn.
  • If at any point while cooking, the onions look too dry, smokes up too much or burns the bottom of the pan, try lowering the heat back to medium if not lower. Add a little bit of oil and keep stirring to avoid further burning or drying out.
  • If your sambal looks too oily after cooking, use a drainer to drain the excessive oil from the onion sambal. This may take about 5-10 minutes.

Berry-secret note

On a busy day, when in need of this sambal, I go into all-in-one-go-mode.

First, I gather all the ingredients to cut and prep as needed. Throw it all in a non-stick pan with a lid to cover and cook on low/medium heat for about 5 minutes. Take the lid off, stir and cook for about 10 more minutes, remember to stir as you go and it’s done.

The overall cooking process can take between 15-20 minutes or even less, depending on the number of onions used. Just remember to stir in between cooking.

This way I can cut, prep, throw it all together and cook in one go. While that’s being made I’d be multi-tasking with another dish to complete a meal for the day.
