If you don't usually keep Hawaiian sweet rolls in your pantry, you'll need to pick some up at the supermarket. These rolls are key to achieving the perfect balance of sweetness in the sandwiches. Additionally, poppy seeds and Worcestershire sauce might not be common in every household, so make sure to grab those as well.

How to Store / Freeze These Sandwiches
- Allow the baked Hawaiian sandwiches to cool completely before storing. This helps prevent condensation, which can make the rolls 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. This keeps the ham and cheese fresh and safe to eat.
- For longer storage, place the wrapped sandwiches in a freezer-safe container or a freezer bag. Label the container with the date to keep track of how long they've been stored.
- When ready to eat, thaw the sandwiches in the refrigerator overnight if they were frozen. This ensures even thawing and maintains the texture of the bread.
- Reheat the sandwiches in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until they are warmed through and the cheese is melted. This brings back the crispiness of the rolls and the gooeyness of the cheese.
- Alternatively, you can reheat the sandwiches in a microwave for 1-2 minutes, though this method may result in a softer texture. To maintain some crispiness, consider using a microwave-safe crisper tray.
- Enjoy your reheated baked Hawaiian sandwiches with a side of potato salad, coleslaw, or even a fresh fruit salad for a complete meal.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover Hawaiian sandwiches in an oven-safe dish. Cover them with aluminum foil to prevent them from drying out. Bake for about 10-15 minutes, or until the ham and swiss cheese are heated through and the tops are slightly crispy.
For a quicker method, use a microwave. Place the sandwiches on a microwave-safe plate. Cover them with a damp paper towel to keep them moist. Heat on medium power for 1-2 minutes, checking halfway through to ensure they are warming evenly.
If you have an air fryer, preheat it to 350°F (175°C). Place the sandwiches in the air fryer basket in a single layer. Heat for about 3-5 minutes, or until the cheese is melted and the tops are crispy.
For a stovetop method, use a skillet over medium heat. Place the sandwiches in the skillet and cover with a lid. Heat for about 3-5 minutes on each side, or until the ham and cheese are warmed through and the rolls are slightly toasted.
