Technique Tip for This Recipe
When preparing the butter mixture, make sure to thoroughly whisk together the melted butter, dijon mustard, poppy seeds, worcestershire sauce, and onion powder. This ensures that all the flavors are evenly distributed. Additionally, when pouring the mixture over the sandwiches, use a pastry brush to spread it evenly across the tops and sides of the slider rolls.

How To Store or Freeze These Party Sandwiches
- Allow the baked ham and cheese party 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. This ensures they stay fresh and prevents them from sticking together.
- Place the wrapped sandwiches in an airtight container or a resealable plastic bag. This adds an extra layer of protection against moisture and air.
- Store the container or bag in the refrigerator if you plan to consume the sandwiches within 3-4 days. For longer storage, place them in the freezer.
- When freezing, label the container or bag with the date. This helps you keep track of how long the sandwiches have been stored.
- To reheat refrigerated sandwiches, preheat your oven to 350°F (175°C). Place the sandwiches on a baking sheet and cover them loosely with aluminum foil. Bake for 10-15 minutes, or until heated through.
- For frozen sandwiches, allow them to thaw in the refrigerator overnight before reheating. Alternatively, you can reheat them directly from frozen by baking at 350°F (175°C) for 20-25 minutes, covered with foil.
- If you prefer a quicker reheating method, use a microwave. Unwrap the sandwich and place it on a microwave-safe plate. Heat on medium power for 1-2 minutes, or until the cheese is melted and the sandwich is warmed through.
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 about 10-15 minutes, or until the cheese is melted and the sandwiches are heated through.
For a quicker option, use a microwave. Place the sandwiches on a microwave-safe plate and cover them with a damp paper towel. Microwave on medium power for 1-2 minutes, checking halfway through to ensure even heating.
If you prefer a crispy texture, use a toaster oven. Set the toaster oven to 350°F (175°C) and place the sandwiches inside. Heat for 10-12 minutes, or until the cheese is melted and the tops are slightly crispy.
For a stovetop method, heat a skillet over medium heat. Place the sandwiches in the skillet and cover with a lid. Cook for about 3-5 minutes on each side, or until the cheese is melted and the sandwiches are warmed through.
