French Grilled Cheese

I watched Ina Garten make a similar dish and had to try it myself. It's way beyond basic grilled cheese. Yum!

• Ready In: 35 mins
• Serves: 4

Ingredients

• 2  tablespoons butter
• 3  tablespoons all-purpose flour
• 2  cups  whole milk, scalded but not boiling
• 1⁄2 teaspoon salt
• 1⁄2 teaspoon  garlic salt
• 10  ounces swiss cheese, grated
• 3⁄4 cup  freshly grated parmesan cheese
• 1⁄2 lb ham, sliced thin from the deli
• 1⁄4 cup Dijon mustard
• 16  slices  rustic  white bread, sliced with crust removed

Directions

1. Preheat oven to 400°F
2. Melt butter over low heat in small saucepan. Whisk in flour until blended. Continue to stir and cook butter and flour for 1-2 minutes. Slowly add scalded milk, whisking continually, until mixture is smooth and thickened. Remove from heat, stir in salt, garlic salt, 1/2 cup Swiss cheese and all of Parmesan cheese until cheese is melted and set aside.
3. Toast bread slices on large baking sheet on both sides under broiler until golden brown. Remove from oven.
4. Brush each bread slice with Dijon mustard. Place sliced ham on half of bread slices and top each with 1/2 of remaining Swiss cheese and remaining 1/2 of bread slices. Spread reserved cheese sauce over tops of sandwiches, sprinkle with left over Swiss cheese.
5. Bake sandwiches for 5 minutes. Place under broiler for additional 2-4 minutes, or until tops are browned and bubbly. Watch closely to avoid burning tops. Serve immediately.
