St. Patrick’s Day sandwiches are meant to be filling, a little messy, and completely satisfying. This is not the day for light bites. Whether you’re planning a St Patrick’s Day themed lunch, a casual Irish party, or an afternoon appetizer spread after the parade, these sandwiches lean into what works, corned beef stacked high, rye bread grilled until crisp, cheese melted properly, and bold flavors that hold up for big appetites.
1. Classic Corned Beef Reuben on Rye

This is the sandwich people expect on St. Patrick’s Day, and for good reason. A proper Reuben is all about balance: salty corned beef, tangy sauerkraut, creamy dressing, and rye bread that stays crisp instead of soggy. If you get the layering right and take your time grilling, this sandwich easily satisfies the biggest appetites.
Ingredients
- Rye bread slices
- Thinly sliced cooked corned beef
- Swiss cheese slices
- Sauerkraut, well drained
- Thousand Island dressing
- Unsalted butter, softened
Instructions
- Lay out the rye bread slices on a cutting board. Butter one side of each slice evenly.
- Flip the bread over and spread Thousand Island dressing on the unbuttered sides.
- Layer Swiss cheese first, then a generous portion of corned beef, followed by sauerkraut, and another slice of Swiss cheese.
- Top with the second slice of bread, buttered side facing out.
- Heat a skillet over medium heat. Place the sandwich in the pan and grill slowly, pressing lightly.
- Cook until the bread is golden and the cheese has started melting, about 3–4 minutes per side.
- Remove from heat and let it rest for one minute before slicing.
How to Serve
Cut the sandwich in half diagonally and serve it hot while the cheese is still pulling. Place it on a plate with kettle chips or a small scoop of potato salad. If you’re serving this as part of a St Patrick’s Day afternoon appetizer table, slice each half again so it’s easier to pick up and share.
2. Grilled Corned Beef and Swiss Melt

This sandwich is for people who want all the comfort without too many extras. It skips the sauerkraut and dressing and focuses on corned beef and Swiss cheese melted properly between crisp slices of bread. It’s simple, hearty, and great when feeding a crowd that prefers familiar flavors.

6. Cashel Blue Cheese and Roast Beef Sandwich
