  • Cusine


8 slices gluten-free white sandwich bread, homemade or store-bought

2 tablespoons unsalted butter

3 tablespoons sweet rice flour

2 1/2 cups whole or 2% milk, warmed

1/4 teaspoon salt

1/2 teaspoon freshly ground black pepper

8 ounces Gruyère cheese, grated

1/4 cup freshly grated parmesan cheese

Dijon mustard

1/2 pound thinly sliced ham


Preheat the oven to 425ºF. Place the bread on an 18 by 13-inch rimmed baking sheet. Bake, flipping once, until the slices begin to turn golden brown. Remove from the oven and set aside. Leave the oven on. Prepare the sauce: In a small pot, melt the butter. Add the sweet rice flour. Cook for 3 minutes, whisking constantly. The paste will turn a light golden brown. In a slow and steady steam, add the milk. Cook, whisking constantly, until the sauce begins to bubble. Season with salt and pepper. Stir in 1/4 cup of the Gruyère and all of the parmesan. Whisk until smooth. Make the sandwiches on the baking sheet. Spread a thin coat of mustard on each piece of bread. Place a few slices of ham and a generous sprinkle of Gruyère on each of 4 bread slices. (Reserve about one-quarter of the cheese.) Top with a second slice of bread, mustard side down. Spoon a generous amount of white sauce onto each sandwich. Divide the remaining Gruyère over the top. Return the sandwiches to the oven. Bake for 5 minutes to heat. Turn on the broiler. Broil until the cheese is melted, light brown, and bubbling. Serve immediately.
