Hot & Melty Oven Baked Ham & Swiss Sandwiches

My grandma, bless her heart, had a knack for whipping up simple yet soul-satisfying dishes. I remember one Christmas Eve, the air thick with the scent of pine and anticipation, when she unveiled a tray of these glorious Ham and Swiss sliders. The buttery aroma alone was enough to make my mouth water, but the first bite – oh, that was pure magic! The soft, sweet Hawaiian rolls yielding to warm, salty ham and gooey Swiss, all bathed in a savory-sweet mustard glaze… it was comfort food elevated to an art form, and a memory I cherish to this day.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 15 minutes
• Total Time: 30 minutes
• Servings: 12
• Dietary Type: Comfort Food

Ingredients

• 1 (12 count) package King’s Hawaiian Rolls
• 18 slices Swiss cheese, 1/2 slice per sandwich
• 16 ounces sliced ham, Use a good deli ham. About 1/2 pound is sufficient for 12 rolls.
• 1/2 cup butter, melted
• 1 teaspoon stone ground grainy mustard, use a good brown grainy mustard
• 1 teaspoon poppy seed (optional)
• 2 teaspoons onion flakes, dried
• 2 tablespoons Worcestershire sauce

Equipment Needed

• Small saucepan
• 9×13 inch baking dish or foil-lined baking sheet
• Pastry brush
• Aluminum foil

Instructions

1. In a small saucepan over low heat, combine the melted butter, stone ground grainy mustard, poppy seeds (if using), dried onion flakes, and Worcestershire sauce.
2. Heat the mixture until the butter is completely melted and the onion flakes are hydrated, about 5 minutes. Remove from heat and set aside. The aroma at this point is truly intoxicating!
3. Slice all of the King’s Hawaiian rolls in half horizontally, creating a top and bottom section.
4. Place the bottom halves of the rolls in a 9×13 inch baking dish or on a foil-lined baking sheet.
5. Lightly brush the bottom halves of the rolls with the buttery mustard sauce. You don’t need to saturate them, just a thin, even coating will do.
6. Divide the sliced ham and Swiss cheese evenly among all the bottom halves of the sliced rolls. Be generous! If it fits comfortably, go for it. The more cheese, the gooier and more delicious the sandwiches will be.
7. Cover the filled bottom halves with the top halves of the King’s Hawaiian rolls, creating the assembled sandwiches.
8. Spoon the remaining buttery mustard sauce evenly over the tops of the sandwiches. Ensure each sandwich is adequately glazed for maximum flavor.
9. Cover the baking dish with aluminum foil. At this point, you can either bake immediately or refrigerate for later.
10. Refrigerate the covered sandwiches for at least one hour, or ideally, overnight. This allows the flavors to meld together beautifully and ensures the rolls don’t dry out during baking.
11. When ready to bake, preheat your oven to 350°F (175°C).
12. Place the covered baking dish on the middle rack of the preheated oven and bake for 10 minutes.
13. Remove the aluminum foil and continue baking for an additional 5 minutes (for a total baking time of 15 minutes) or until the sandwiches are warmed through, the cheese is delightfully gooey and melted, and the tops of the rolls are golden brown.
14. If needed, add an additional minute or two of baking time to achieve your desired level of cheesiness and browning. Keep a close eye on them to prevent burning.
15. Remove from the oven and serve immediately.

Expert Tips & Tricks

• For a more intense mustard flavor: Use Dijon mustard in addition to, or instead of, the stone ground mustard.
• Don’t overbake: Overbaking can result in dry rolls. Keep a close eye on the sandwiches, especially during the last few minutes of baking.
• Adjust the ham and cheese: Feel free to adjust the amount of ham and cheese to your liking. If you prefer a cheesier sandwich, add more cheese!
• Use a serrated knife: When slicing the rolls, use a serrated knife for a clean, even cut without tearing the soft bread.
• Prevent soggy bottoms: Line the baking dish with parchment paper for easy cleanup and to prevent the bottoms of the rolls from becoming soggy.
• Make it ahead: Prepare the sandwiches completely, cover tightly with foil, and refrigerate for up to 24 hours before baking. This is a great option for parties or gatherings.

Serving & Storage Suggestions

Serve these Hot & Melty Ham & Swiss Sandwiches immediately while they are warm and the cheese is gooey. They are fantastic on their own or as part of a larger meal. Consider serving them with a side of potato salad, coleslaw, or a simple green salad.

Leftover sandwiches can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, wrap the sandwich in foil and bake in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until warmed through. You can also microwave them, but the rolls may become slightly softer.

While freezing is not recommended, you can freeze individual sandwiches. Wrap them tightly in plastic wrap and then in foil. Thaw overnight in the refrigerator and then reheat as directed above.
