Onion sandwiches are a staple in many cuisines around the world, and for good reason. They’re simple, flavorful, and can be customized to suit any taste. Whether you’re a fan of sweet caramelized onions or pungent raw onions, there’s an onion sandwich out there for you. In this article, we’ll take you through the steps to make the perfect onion sandwich, from preparation to assembly.
Choosing the Right Onions
The type of onion you use can make or break your sandwich. There are several varieties to choose from, each with its own unique flavor and texture.
Yellow Onions
Yellow onions are the most commonly available variety and are great for caramelizing. They have a strong, sweet flavor and a firm texture that holds up well to cooking.
Red Onions
Red onions are sweeter and milder than yellow onions, with a beautiful deep red color. They’re great for using raw in sandwiches, as they add a pop of color and a touch of sweetness.
Shallots
Shallots are a type of onion that’s smaller and milder than yellow onions. They have a delicate flavor and a soft texture, making them great for using raw in sandwiches.
Scallions
Scallions, also known as green onions, are a type of onion that’s harvested before the bulb forms. They have a mild flavor and a crunchy texture, making them great for adding a fresh flavor to sandwiches.
Preparing the Onions
Once you’ve chosen your onions, it’s time to prepare them for your sandwich. Here are a few ways to prepare onions, depending on the type of sandwich you’re making:
Caramelizing Onions
Caramelizing onions is a process that brings out the natural sweetness in onions. To caramelize onions, heat a tablespoon of oil in a pan over medium-low heat. Add sliced onions and cook, stirring occasionally, for 30-40 minutes or until the onions are deep golden brown.
Roasting Onions
Roasting onions is a great way to bring out their natural sweetness without the need for constant stirring. To roast onions, preheat your oven to 400°F (200°C). Slice the onions and place them on a baking sheet lined with parchment paper. Drizzle with oil and season with salt and pepper. Roast for 30-40 minutes or until the onions are tender and caramelized.
Grilling Onions
Grilling onions adds a smoky flavor to your sandwich. To grill onions, preheat your grill to medium-high heat. Slice the onions and brush with oil. Season with salt and pepper. Grill for 5-7 minutes per side or until the onions are tender and slightly charred.
Assembling the Sandwich
Now that your onions are prepared, it’s time to assemble your sandwich. Here are a few tips to keep in mind:

What is the best type of onion to use for an onion sandwich?
The best type of onion to use for an onion sandwich is a matter of personal preference. Some people prefer sweet onions like Vidalia or Maui, while others like the pungency of yellow or white onions. If you want a sweeter onion flavor, go for the Vidalia or Maui. If you prefer a stronger onion flavor, go for the yellow or white onion.
It’s also worth noting that the type of onion you choose will affect the texture of the sandwich. Sweet onions tend to be softer and more prone to caramelization, while yellow and white onions are firmer and hold their shape better. So, if you want a crunchy onion texture, go for the yellow or white onion.
How do I caramelize onions for an onion sandwich?
Caramelizing onions is a simple process that brings out the natural sweetness in onions. To caramelize onions, heat some oil in a pan over medium-low heat. Add sliced onions and cook, stirring occasionally, for about 30-40 minutes or until they turn golden brown. You can also add a pinch of salt and a sprinkle of sugar to enhance the flavor.
It’s essential to cook the onions slowly and patiently, as high heat can burn them. Stir the onions occasionally to prevent burning and promote even cooking. You can also add a little liquid, such as wine or broth, to the pan to help the onions cook more evenly. Once the onions are caramelized, let them cool before using them in your sandwich.
What type of bread is best for an onion sandwich?
The type of bread you choose for an onion sandwich can make a big difference in the overall flavor and texture. A crusty bread, such as baguette or ciabatta, is ideal for an onion sandwich. The crunchy crust provides a nice contrast to the soft onions and any other fillings you may add.
You can also use a hearty bread, such as sourdough or whole wheat, for a more robust flavor. Avoid using a soft, fluffy bread, such as white bread, as it can become soggy with the onions and other fillings. Toasting the bread before assembling the sandwich can also help keep it crispy.
What are some popular fillings to add to an onion sandwich?
There are many delicious fillings you can add to an onion sandwich to enhance the flavor. Some popular options include cheese, such as cheddar or Swiss, which melts beautifully and adds a rich flavor. You can also add sliced meats, such as roast beef or turkey, for added protein.
Other popular fillings include avocado, which adds a creamy texture, and bacon, which adds a smoky flavor. You can also add some fresh herbs, such as parsley or thyme, for a bright, refreshing flavor. The key is to balance the flavors and textures so that the onions remain the star of the show.
How do I assemble an onion sandwich?
Assembling an onion sandwich is a straightforward process. Start by spreading a layer of caramelized onions on one slice of bread. Add any other fillings you like, such as cheese or sliced meats, on top of the onions. Place the second slice of bread on top to complete the sandwich.
You can also add some condiments, such as mayonnaise or mustard, to the bread for added flavor. Be careful not to overfill the sandwich, as the onions and other fillings can make it messy. You can also grill or toast the sandwich for a crispy texture and melted cheese.
Can I make an onion sandwich ahead of time?
While it’s best to assemble an onion sandwich just before serving, you can make some components ahead of time. Caramelized onions can be made up to a day in advance and stored in the fridge. You can also toast the bread ahead of time and store it in an airtight container.
However, it’s best to assemble the sandwich just before serving, as the onions and other fillings can make the bread soggy. If you need to make the sandwich ahead of time, consider using a crusty bread that can hold up to the fillings. You can also assemble the sandwich and store it in the fridge for up to an hour before serving.
How do I store leftover onion sandwiches?
If you have leftover onion sandwiches, you can store them in the fridge for up to a day. Wrap the sandwich tightly in plastic wrap or aluminum foil to prevent the bread from getting soggy. You can also store the components separately, such as the caramelized onions and toasted bread, and assemble the sandwich just before serving.
It’s best to consume the sandwich within a day, as the onions and other fillings can lose their flavor and texture over time. You can also freeze the sandwich for up to a month, but the texture and flavor may not be as fresh.
