Gluten-Free Croque-Monsieur Recipe

• 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 Gruyere cheese, grated (about 2 cups)
• 1/4 cup freshly grated parmesan cheese
• Dijon mustard
• 1/2 pound thinly sliced ham

1. Preheat the oven to 425u0b0F. 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.
2. 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 Gruyere and all of the parmesan. Whisk until smooth.
3. 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 Gruyere 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 Gruyere over the top.
4. Return the sandwiches to the oven. Bake for 5 minutes to heat.
5. Turn on the broiler. Broil until the cheese is melted, light brown, and bubbling. Serve immediately.
