These baked ham and cheese party sandwiches are perfect for any gathering. They are easy to make, delicious, and sure to be a hit with your guests. The combination of ham and swiss cheese nestled in hawaiian rolls and topped with a flavorful butter mixture makes for an irresistible treat.
If you don't usually have hawaiian rolls or poppy seeds in your pantry, you might need to pick them up at the supermarket. Hawaiian rolls are sweet, soft rolls that add a unique flavor to the sandwiches. Poppy seeds add a slight crunch and a nutty flavor to the butter mixture.

Ingredients For Baked Ham And Cheese Party Sandwiches
Hawaiian rolls: Soft, sweet rolls that provide a unique flavor and texture.
Ham: Thinly sliced deli ham, providing a savory and salty taste.
Swiss cheese: Mild, nutty cheese that melts beautifully.
Butter: Melted to create a rich, flavorful topping.
Dijon mustard: Adds a tangy and slightly spicy flavor to the butter mixture.
Poppy seeds: Provide a slight crunch and nutty flavor.
Minced onion: Adds a bit of sweetness and texture.
Worcestershire sauce: Adds a deep, umami flavor to the butter mixture.
Technique Tip for Making These Party Sandwiches
When preparing the butter mixture for these sandwiches, make sure to mince the onion very finely. This ensures that the flavors are evenly distributed and that you don't end up with large chunks of onion in your sandwiches. Additionally, when pouring the butter mixture over the sandwiches, use a pastry brush to ensure that every roll is well-coated, which will enhance the flavor and texture of the final dish.

How To Store or Freeze These Party Sandwiches
Allow the sandwiches to cool completely before storing. This helps prevent condensation, which can make the bread soggy.
For short-term storage, place the cooled sandwiches in an airtight container or wrap them tightly with plastic wrap. Store in the refrigerator for up to 3 days.
To reheat refrigerated sandwiches, preheat your oven to 350°F (175°C). Place the sandwiches on a baking sheet and cover with aluminum foil. Bake for about 10-15 minutes, or until heated through.
For longer storage, consider freezing the sandwiches. Wrap each sandwich individually in plastic wrap, then place them in a freezer-safe bag or container. This prevents freezer burn and keeps them fresh for up to 2 months.
When ready to enjoy frozen sandwiches, thaw them in the refrigerator overnight. Reheat as you would refrigerated sandwiches, using the oven method mentioned above.
If you prefer a quicker reheating method, you can use a microwave. Place a thawed sandwich on a microwave-safe plate and cover with a damp paper towel. Microwave on medium power for 1-2 minutes, checking frequently to avoid overcooking.
For an extra crispy texture, consider reheating the sandwiches in a toaster oven. This method helps maintain the bread's crunchiness while ensuring the ham and cheese are thoroughly heated.
Always label your storage containers or bags with the date to keep track of freshness. This ensures you enjoy your baked ham and cheese party sandwiches at their best quality.
How To Reheat Leftovers
Preheat your oven to 350°F (175°C). Wrap the leftover sandwiches in aluminum foil to keep them from drying out. Place them on a baking sheet and heat for about 10-15 minutes, or until the cheese is melted and the ham is warmed through.
For a quicker method, use a microwave. Place the sandwiches on a microwave-safe plate and cover with a damp paper towel. Heat on medium power for 1-2 minutes, checking halfway through to ensure even heating.
If you prefer a crispy top, use a toaster oven. Preheat to 350°F (175°C) and place the sandwiches directly on the rack or on a baking sheet. Heat for 10-12 minutes, or until the tops are golden and the cheese is bubbly.
For a stovetop method, use a skillet over medium heat. Place the sandwiches in the skillet and cover with a lid. Heat for about 5-7 minutes, flipping halfway through, until the cheese is melted and the ham is heated through.
