Instructions

Begin by thinly slicing your yellow onions. Aim for uniform slices for even cooking.
3 large yellow onions
In a large skillet, heat vegetable oil over medium-low heat. Avoid high heat, as this will quickly brown the onions without allowing them to caramelize properly.
5 tbsp vegetable oil
Add the sliced onions to the hot oil and season with a pinch of salt and pepper. Stir occasionally to ensure the onions cook evenly.
1 tsp Salt, Black pepper
Reduce the heat to low and allow the onions to cook slowly. This process can take 30-45 minutes, depending on the amount of onions and the desired level of caramelization.
Resist the urge to crank up the heat! Low and slow cooking is essential for achieving that deep, golden brown color and caramelized sweetness.
The onions are caramelized when they have reached a deep golden brown color and have softened significantly. They should have a slightly jammy texture and a rich, sweet aroma.
While the onions cook, stir them occasionally to prevent sticking and browning too quickly. You want them to soften and caramelize evenly, not burn.
Once caramelized, season the onions with a touch of black pepper (optional) and use them immediately in your favorite recipe or store them for later use.

Notes

Thinly sliced onions will caramelize more evenly and achieve a more consistent texture.

Don't rush the process; allow the onions to cook slowly to achieve the desired caramelization.

While occasional stirring is necessary to prevent sticking, avoid overworking the onions. Excessive stirring can break them down and prevent them from caramelizing properly.

Use a large enough skillet to avoid overcrowding the onions. This allows for even cooking and prevents them from steaming instead of caramelizing.

If the onions start to stick to the pan, you can deglaze the pan with a splash of water, white wine, or even broth. This will loosen any browned bits and add a touch of extra flavor.
