Here are the best onions to pair with burgers and the best ways to prepare them:
Yellow, White and Red Onions
Yellow, white, and red onions are the three most common species of onions. These types of onions appear to be very dense on the outside, yet they are approximately 1.7% fiber, 9% carbohydrates, and 89% water.
Yellow Onions
Out of the three, yellow onions, also known as ‘brown onions’, are the most widely available type of cooking onion. They have a yellow/brown papery skin, and are highly durable. Yellow onions last up to six weeks if stored in your pantry and around two months if refrigerated.
They have the highest sulphur content out of all the existing varieties of onions. As a result, raw yellow onions are more pungent in taste and aroma. However, when cooked, they become slightly sweet and mild in flavor.
How to Prepare: The best ways to prepare yellow onions for burgers are to caramelize, sauté, and roast them. Yellow onions are usually considered as too pungent and intense to be used raw.
White Onions
White onions are very similar to yellow onions in terms of size and shape. They have white papery skin and are much milder in flavor when compared to the yellow onion. White onions also have a crunchier texture than the yellow onion.
The best ways to prepare white onions for burgers are to fry, sauté, caramelize, and grill them. White onions can also be used raw.
Red Onions
Red onions, also commonly referred to as ‘purple onions’, are considerably milder in taste than yellow and white onions. This makes them ideal for recipes that require raw onion, such as salads and of course, burgers!
How to Prepare: The best ways to prepare red onions for burgers are to pickle, sauté, and grill them. Red onions are one of the most ideal types of onion to be eaten raw on burgers.
Scallions and Spring Onions
Scallions, also known as green onions, are simply red, white, or yellow onions that have been harvested early. As a result of this, they are much milder in flavor. Scallions have long, green, leafy stalks with a small bulb at the bottom.
Spring onions are just scallions that have been allowed to mature a bit longer. Spring onions have a bigger bulb than scallions and are also a bit sweeter. Typically, ripe onions are picked during the summer season. Spring onions are picked during the spring season when the onions are not fully ripe.
How to Prepare: The best ways to prepare scallions and spring onions for burgers are to braise, roast, grill, or pickle them.
Sweet Onions
Sweet onions, also known as ‘Vidalia onions’ or ‘Walla Walla,’ are quite similar to yellow onions, but they are generally a bit larger. As the name suggests, sweet onions are naturally sweet due to their low sulfur and higher water content.
How to Prepare: The best ways to prepare sweet onions for burgers are to caramelize, grill, sauté, and fry them. Sweet onions hold the number one spot as the best type of onion that can be paired raw with burgers.
Shallots
Shallots have many similarities with the red onion but are much milder. Some people describe them as having a very mild garlic-type taste as well.
How to Prepare: The best ways to prepare shallots for burgers are to pickle, fry or add them in a delicious salsa. Shallots can also be used raw due to their mild properties.
Leeks
Leeks look very similar to scallions but are much larger in size. Unlike scallions, the green, leafy stalks of leeks are largely inedible. It is for this reason that leeks are never eaten raw.
However, when cooked, they have a mild and sweet onion flavor with a slightly crunchy texture.
How to Prepare: The best ways to prepare leeks for burgers are to roast, sauté, fry, grill or braise them.
