- 2 Thick Slices of Soft White Bread
- ¼ Teaspoon Ground Cinnamon
- 1 Generous Slice of Ham Steak
- ¼ Cup Shredded Gruyère Cheese
- 1 Tablespoon Dijon Mustard
- 1 Sliced Avocado
- 1 Tablespoon Unsalted Butter

Directions
Ready to embark on making this culinary delight? Follow these detailed steps:
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
Here are some useful tips to enhance your experience:
- 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.
Storage Tips
Leftovers? No problem! Here are some storage suggestions:
- Refrigeration: Wrap any leftover sandwiches in plastic wrap or foil and store in an airtight container in the fridge for up to 2 days.
- Reheating: For the best texture, reheat in a toaster oven or skillet rather than a microwave. This keeps it crispy.
- Freezing: You can freeze uncooked sandwiches. Wrap them carefully in foil, then store in a freezer bag. They’ll keep for up to a month.
Serving Suggestions
Here are my top suggestions to serve alongside this dish:
- Fresh Salad: A simple arugula and lemon salad gives a refreshing contrast. The peppery arugula balances the richness of the French toast.
- Roasted Vegetables: Roasted asparagus or zucchini offers natural sweetness and a delightful crunch.
- Fruit Compote: A sweet fig or berry compote brings out the flavors beautifully. The addition of a fruity side uplifts the overall dining experience.
- Chilled Soup: Consider a cold gazpacho. The coolness plays well against the warm, hearty French toast.
- Sparkling Beverage: A glass of sparkling water, perhaps with lemon, cleanses the palate efficiently.
What Other Substitutes Can I Use?
Sometimes, swapping ingredients is fun. Here are some substitutes to consider:
- Cheese Alternatives: Use mozzarella or cheddar if you prefer. Gruyère has a unique flavor, but these options will work too!
- Bread Varieties: Sourdough makes an excellent alternative for a zesty twist. Its chewiness contrasts well with the tender filling.
- Protein Swaps: Turkey or chicken ham offers a lighter take. You won’t lose flavor, just gain some health benefits.
- Veggie Additions: Add sautéed spinach or roasted red peppers for extra nutrients. These vegetables work excellently in this recipe.
- Dijon Substitute: If Dijon is too sharp for your palate, try a sweeter mustard or even a honey mustard for a touch of sweetness.
