What color should caramelized onions look like?

Slowly caramelizing the onions in butter until deeply golden (but not bitterly dark) brings out their natural sweetness and best flavor. Using a wide pan, like a sauté pan, gives the onions plenty of contact with the heat so they brown evenly instead of steaming or scorching.

What are common mistakes when caramelizing onions?

Common mistakes when caramelizing onions include rushing the process with high heat, overcrowding the pan (causing steaming instead of browning), cutting them unevenly, adding too much fat (leading to frying), or removing them too soon before deep flavor develops, all preventing the slow breakdown of sugars for that sweet, rich result. 

How to tell if caramelized onions have gone bad?

What is the color of caramelization?

Caramelization of sucrose produces large brown molecules (caramelan, caramelen, and caramelin) and small, volatile aroma molecules such as furan, maltol, ethyl acetate and diacetyl. The large brown molecules (caramelin, caramelen and caramelan) are what give caramel its color, its viscosity and its stickiness.

What is the trick to caramelizing onions?

The best way to caramelize onions is low and slow, using a heavy pan with butter/oil, adding salt early to draw out moisture, and stirring occasionally, deglazing with water as needed to prevent sticking and build flavor; it takes patience (45-90 mins) for deep sweetness, but a faster method involves a quick steam with water and a lid to wilt them first. 

How long can caramelized onions be in the fridge?

Stored in an airtight container in the fridge, they'll keep for a week. You can also freeze them for up to two months. I like to freeze caramelized onions in ice cube trays.

Should you use butter or oil for caramelizing onions?

For the best flavor and texture, use a combination of butter and oil, as butter adds richness and milk solids help browning, while oil's higher smoke point prevents burning, making it a superior choice to just butter alone, though oil or butter can be used individually. The ideal method involves butter for flavor and oil for heat stability, cooked low and slow with frequent stirring, using water to deglaze the pan as needed for jammy, sweet results, says Serious Eats and Bon Appétit.
 

Is it better to caramelize onions fast or slowly?

Why should onions not be kept in the fridge?

You should not refrigerate whole, uncut onions because the cold, humid environment turns their starches into sugar, making them soft, mushy, and prone to mold, while also causing them to absorb odors from other foods; instead, store them in a cool, dry, well-ventilated spot like a pantry, but keep cut onions in the fridge in an airtight container.

The key is low, slow cooking with occasional stirring, as rushing with high heat will burn them. 

Should onions be covered while caramelizing?

(It's the same principle as when you're roasting vegetables: Pile them on a baking sheet and they'll steam in their own moisture; spread them out and they'll char and brown.) Second, cover the pan for the first 15 minutes of cooking, during which the onions will soften in their own moisture.

Is it best to caramelize onions in butter or oil?

You can use either oil or butter to caramelize onions — but ideally, you use a combination of both! I like to use olive oil, and this cooking fat tolerates heat particularly well. Meanwhile, butter adds a distinctly rich flavor to the caramelized onions.
