These baked Hawaiian sandwiches are a delightful blend of savory and sweet flavors, perfect for any gathering or a simple family meal. The combination of ham and swiss cheese nestled in soft Hawaiian rolls creates a mouthwatering treat that is both satisfying and easy to prepare. The buttery topping with dijon mustard, poppy seeds, and minced onion adds an extra layer of flavor that elevates these sandwiches to a whole new level.
While most of the ingredients for this recipe are common, you might need to pay special attention to Hawaiian rolls. These sweet, fluffy rolls are essential for the unique flavor of the sandwiches and can usually be found in the bakery section of your supermarket. If you can't find them, any soft, sweet roll will work as a substitute.

Ingredients For Baked Hawaiian Sandwiches Recipe
Ham: Thinly sliced, providing a savory and salty flavor that pairs well with the sweetness of the rolls.
Swiss cheese: Adds a creamy, slightly nutty taste that melts beautifully over the ham.
Hawaiian rolls: Soft, sweet rolls that are the perfect base for these sandwiches.
Butter: Melted and mixed with other ingredients to create a flavorful topping.
Dijon mustard: Adds a tangy, slightly spicy kick to the butter mixture.
Poppy seeds: Provide a subtle crunch and a hint of nutty flavor.
Minced onion: Adds a touch of sweetness and depth to the butter mixture.
Technique Tip for Making These Sandwiches
To ensure the ham and swiss cheese are evenly distributed and the sandwiches hold together well, consider slightly overlapping the slices of ham and cheese as you layer them on the hawaiian rolls. This technique helps create a more cohesive bite and prevents the ingredients from slipping out when you cut or serve the sandwiches. Additionally, for an extra burst of flavor, you can lightly toast the rolls before assembling the sandwiches, which adds a delightful crunch and enhances the overall texture.

How to Store or 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 eat 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 bag. Label it with the date to keep track of how long they’ve been stored.
- Freeze the sandwiches for up to 2 months. This ensures they maintain their quality and flavor.
- To reheat, preheat your oven to 350°F (175°C). Remove the sandwiches from the wrapping and place them on a baking sheet.
- Cover the sandwiches loosely with aluminum foil to prevent the tops from browning too quickly.
- Bake for 15-20 minutes or until the cheese is melted and the sandwiches are heated through. This brings back the original texture and taste.
- Alternatively, you can reheat individual sandwiches in the microwave. Unwrap the sandwich and place it on a microwave-safe plate. Heat on medium power for 1-2 minutes, checking to ensure it’s heated evenly.
- Enjoy your reheated baked Hawaiian sandwiches warm, just like when they were freshly made.
How to Reheat Leftovers
Preheat your oven to 325°F (165°C). Place the leftover sandwiches on a baking sheet and cover them with aluminum foil to prevent them from drying out. Heat for about 15-20 minutes or until the cheese is melted and the sandwiches are warmed through.
If you're in a hurry, 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 they are heating evenly.
For an extra crispy top, use a toaster oven. Set it to 325°F (165°C) and place the sandwiches inside. Heat for about 10-15 minutes, keeping an eye on them to make sure the tops don't burn.
If you have an air fryer, preheat it to 320°F (160°C). Place the sandwiches in the basket and heat for 5-7 minutes. This method will give you a nice, crispy exterior while keeping the inside warm and gooey.
For a stovetop method, use a skillet over medium-low heat. Place the sandwiches in the skillet and cover with a lid. Heat for about 5-7 minutes, flipping halfway through to ensure even warming. This method works well if you want a slightly toasted bottom.
