It's simple, full of flavor, and absolutely delicious! Chances are, you already have the main ingredients right in your kitchen—bread and cheese.
Ingredients
- 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
Instructions
- 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!
Notes
- 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.
