Prepare the shallots by peeling the skin off and washing them with water. Drain the water thoroughly.
Then, evenly slice the shallots by cutting them crosswise at about 2mm thick.
Next, prepare a pan with unheated oil, just enough for deep-frying all the sliced shallots.
Combine the shallots with oil and fry on low heat.
Continuously stir the shallots, making sure there are no clumps.
Wait until the shallots float to the top of the oil and turn lightly golden brown.
Then, immediately transfer shallots to a baking sheet lined with parchment paper or paper towel.
Spread the shallots evenly on a single layer and let it cool.
Once completely cooled, transfer the fried shallots to your preferred dry glass jar and pour in the excess cooled oil as well. You can also keep the extra oil in a separate glass jar to use as a shallot-infused oil.
