While most of the ingredients for this recipe are common, you might need to check your pantry for poppy seeds and dijon mustard. These ingredients add a unique flavor and texture to the sandwiches.

Ingredients For Baked Ham And Cheese Party Sandwiches
Hawaiian rolls: Soft, sweet rolls that are perfect for these sandwiches.
Ham: Thinly sliced deli ham works best for layering.
Swiss cheese: Provides a mild, nutty flavor that pairs well with the ham.
Butter: Melted to create a rich, flavorful topping.
Dijon mustard: Adds a tangy kick to the butter mixture.
Poppy seeds: Give a slight crunch and visual appeal to the sandwiches.
Minced onion: Adds a subtle onion flavor to the topping.
Worcestershire sauce: Enhances the savory flavor of the butter mixture.
Technique Tip for Making These Party Sandwiches
When preparing the butter mixture, ensure that the minced onion is finely chopped to allow for even distribution of flavor. Additionally, let the butter cool slightly after melting to prevent it from cooking the other ingredients prematurely. This will help the dijon mustard and worcestershire sauce blend more smoothly, creating a cohesive and flavorful topping for the sandwiches.

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.
- Wrap each sandwich individually in plastic wrap or aluminum foil to maintain freshness and prevent them from sticking together.
- Place the wrapped sandwiches in an airtight container or a resealable plastic bag. This will help keep out any unwanted odors and maintain the flavor.
- Store the container or bag in the refrigerator if you plan to consume the sandwiches within 3-4 days. This keeps the ham and cheese fresh and safe to eat.
- For longer storage, place the wrapped sandwiches in a single layer on a baking sheet and freeze for about 1-2 hours. This initial freezing step prevents them from sticking together.
- Once the sandwiches are frozen solid, transfer them to a resealable freezer bag or an airtight container. Label the container with the date to keep track of their freshness.
- When ready to enjoy, thaw the sandwiches in the refrigerator overnight. This slow thawing process helps maintain the texture and flavor.
- To reheat, preheat your oven to 350°F (175°C). Place the sandwiches on a baking sheet and cover with aluminum foil. Bake for 10-15 minutes or until heated through. Remove the foil for the last few minutes to crisp up the bread if desired.
- Alternatively, you can reheat individual sandwiches in the microwave. Wrap in a damp paper towel and microwave on medium power for 1-2 minutes, checking frequently to avoid overcooking.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover sandwiches on a baking sheet and cover them with aluminum foil. Bake for 10-15 minutes or until the cheese is melted and the ham is heated through.
For a quicker method, use a microwave. Place the sandwiches on a microwave-safe plate and cover them with a damp paper towel to retain moisture. Microwave on medium power for 1-2 minutes, checking halfway to ensure even heating.
If you prefer a crispy texture, use a toaster oven. Set it to 350°F (175°C) and place the sandwiches inside. Toast for about 10 minutes or until the cheese is bubbly and the rolls are slightly crispy.
For an alternative method, use a skillet. Heat the skillet over medium heat and place the sandwiches in it. Cover with a lid and cook for 3-4 minutes on each side, or until the cheese is melted and the ham is warmed through.
