The Corned Beef Sandwich Recipe creates a classic and hearty sandwich perfect for any occasion. It features buttery toasted bread filled with caramelized onions, deli-sliced corned beef, and Swiss cheese, flavored with Worcestershire sauce and grainy mustard for a tangy kick.

To make this sandwich, start by caramelizing onions until golden brown, then mix them with corned beef, Worcestershire sauce, and mustard. Layer this mixture with Swiss cheese between slices of bread and toast until golden and the cheese melts.

Serve these sandwiches warm, ideally with a side of crispy potato chips, a simple green salad, or alongside pickles for extra crunch. They make a satisfying lunch or dinner option, especially when you’re craving comfort food with a touch of tangy flavors.

For storing leftovers, wrap the sandwiches individually in foil or store them in an airtight container in the refrigerator for up to 2 days. Reheat in the oven or toaster oven until warmed through, ensuring the bread stays crisp and the cheese melts again.

  • 1 ½ tbsp Butter divided
  • 1 small Onion thinly sliced
  • 1 tbsp Sugar
  • ½ tsp Salt
  • ¼ tsp Ground black pepper
  • 2 ounces Deli-sliced corned beef cut into strips
  • 2 tsp Worcestershire sauce
  • 1 tbsp Grainy mustard
  • 4 slices Swiss cheese or any cheese you prefer
  • 4 slices Rye bread or any bread you prefer


  • In a large skillet over medium-high heat, melt ½ tablespoon butter. Add sliced onion, sugar, salt, and black pepper. Cook, stirring regularly, until onions are soft, translucent, and golden brown, about 10-15 minutes.
  • Remove skillet from heat. Stir in corned beef, Worcestershire sauce, and mustard until well combined. Set aside momentarily.
  • On 4 slices of bread, place a slice of cheese on each. Divide the corned beef mixture evenly between two slices of bread over the cheese. Top each with another slice of bread to make two sandwiches.
  • In the same skillet over medium-high heat, melt 1 tablespoon butter. If needed, cook sandwiches one at a time. Toast sandwiches on one side until golden brown, then flip with a spatula, pressing down gently as they cook.
  • Once bread is toasted and cheese has melted, carefully remove sandwiches from skillet and serve warm. Enjoy this delicious St. Patrick’s Day treat!


  • Use thick-sliced Swiss cheese for better melting. Shredded cheese works well too.
  • A cast-iron skillet heats evenly and gives sandwiches a nice crunch, but a non-stick skillet is also suitable.
  • Adjust heat as needed to prevent sandwiches from burning too quickly.

Can I Use Different Types of Bread For This Sandwich?

Can I Use Different Types of Bread For This Sandwich?

Yes, you can! While rye bread is traditional and complements the flavors of corned beef well, you can use other types of bread like sourdough, whole wheat, or even a hearty white bread. Choose a bread that you enjoy and that can hold up to toasting and filling without becoming too soggy.

Can I Prepare the Caramelized Onions Ahead of Time?

Absolutely! Caramelized onions can be made ahead and stored in the refrigerator for up to 3-4 days. Simply reheat them gently on the stove or in the microwave before assembling your sandwiches. This makes it easier to whip up these sandwiches quickly for a meal or snack.

What Are Some Good Sides to Serve With This Sandwich?

This sandwich pairs well with a variety of sides. For a classic pairing, serve it with a side of potato chips or a simple green salad. If you’re looking for something heartier, consider serving it with a warm bowl of soup such as tomato soup or creamy potato soup. You can also serve it alongside pickles or coleslaw for added crunch and flavor contrast.
