Ingredients
Method
Step 1: Prepare the Béchamel Sauce
- In a small saucepan, melt 1 tablespoon of unsalted butter over medium heat. Once melted, add 1 tablespoon of flour. Whisk it together to create a roux, cooking for about 1 minute until it’s slightly golden. This ensures a nutty flavor. Gradually pour in ¾ cup of whole milk while whisking continuously to avoid lumps. Cook, stirring until the sauce thickens—this should take about 3-5 minutes. Season with salt, freshly ground pepper, and garlic powder. Just a pinch of nutmeg rounds it out beautifully. Set the sauce aside.
Step 2: Assemble the Sandwich
- Spread 1 tablespoon of Dijon mustard on one side of each slice of bread. This is where the magic starts. Layer one slice with the ham and ¼ cup of Gruyère cheese. You can also add a slice of avocado for added creaminess if desired. Place the second slice on top, mustard-side down to form a sandwich.
Step 3: Prepare the Egg Mixture
- In a bowl, beat 1 large egg along with ¼ teaspoon of ground cinnamon. Mix until well combined. This sweet egg mixture is crucial for that French toast transformation.
Step 4: Cook the Sandwich
- Preheat your skillet over medium-low heat and add 1 tablespoon of unsalted butter. Carefully dip the assembled sandwich into the egg mixture, coating both sides well. Place the sandwich in the skillet. Cook for about 3-4 minutes per side, or until golden brown and the cheese is melted. Adjust heat as necessary to avoid burning.
Step 5: Serve with Béchamel
- Once your sandwich is perfectly crispy, slice it in half. Pour the béchamel sauce over the top. You can sprinkle extra cheese or even some fresh herbs for garnish. Serve warm and savor the combination of flavors.
Notes
- Choose Quality Ingredients: The ham and cheese make or break the dish, so select high-quality, flavorful options.
- Bread Matters: A thicker bread like brioche or challah can elevate the dish.
- Make It Ahead: You can prepare the sandwich filling in advance and then dip it in the egg mixture just before frying.
- Add Layers: Feel free to add sautéed mushrooms or spinach for a gourmet twist.
- Garnishes: Chopped chives or parsley lifts the dish visually and adds freshness.
