Using a serrated knife, slice the Hawaiian rolls in half horizontally to create a top and bottom slab. Place the bottom half in a baking dish. An 10 inch by 8 1/2 inch pan fit the rolls perfectly.
Spread 1 ½ tablespoons of Dijon mustard over the bottom slab. Layer with Swiss cheese, ham, and then provolone.
Bake for 10 minutes to start melting the cheese.
While that bakes, melt the butter in a small saucepan over low heat. Stir in the maple syrup, 1 teaspoon Dijon mustard, everything bagel seasoning, thyme, salt, and pepper.
Place the top slab of rolls over the warm sandwiches. Spoon the butter mixture evenly over the top.
Return to the oven and bake for another 20-25 minutes, until the tops are golden and slightly crisp. Serve with pickles or a tangy slaw to cut through the richness.
Notes
Don’t separate the rolls before slicing — keep the slab intact and slice horizontally to make assembly fast and even.
Skip the Dijon for younger eaters or sub with honey mustard for a milder flavor.
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in a toaster oven or covered in foil in the oven until warmed through. Leftovers reheat well in a toaster oven or air fryer—5 minutes at 350°F gets them crisp and gooey again.
