Scale
Béchamel Sauce
- 20g salted butter
- 20g plain flour
- 250ml whole milk
- 1/4 nutmeg, finely grated
- 2 tsp Marmite (divided, 1 tsp in sauce, 1 tsp to spread)
- 2 tbsp Dijon mustard
- 250g Gruyère, grated (divided, 50g in sauce, rest for topping)
- 50g cheddar, grated
Sandwich
- 8 thick slices white bread
- 4 slices ham
For Cooking
- 1 tbsp vegetable oil (for frying eggs, optional)
- 4 eggs (optional)
To Serve
- Salad (vinegary, optional)
Instructions
- Make the béchamel sauce: Melt the butter in a pan over medium heat; once foaming, sprinkle in the flour and stir to form a paste. Cook for 1 minute, stirring constantly to avoid lumps.
- Add milk gradually: Pour in the milk a splash at a time, stirring continuously until the sauce is smooth and thickened.
- Season and flavor the sauce: Whisk in the grated nutmeg, 1 teaspoon of Marmite, and Dijon mustard. Season with black pepper and a pinch of salt to taste.
- Add cheeses: Remove the pan from heat and stir in 50g of Gruyère and all the cheddar until melted and fully combined. Set aside.
- Toast the bread: Preheat the grill to high. Place the bread slices on a large baking tray under the grill for 2-3 minutes until golden. Flip them over so the untoasted side is facing up.
- Assemble base layer: Spread each untoasted side of bread with a smear of the remaining Marmite, then sprinkle over the remaining grated Gruyère. Grill for a few minutes until the cheese melts.
- Add ham and close sandwiches: Top half of the slices with ham, then cover with the other bread slices. Spread 3-4 tablespoons of the béchamel sauce generously over the top of the closed sandwiches.
- Finish under the grill: Return the sandwiches to the grill for several minutes until the béchamel is golden, bubbling, and has a few charred spots.
- Cook eggs if using: Heat vegetable oil in a small frying pan over medium heat. Crack in eggs and fry to your preferred doneness. Drain on kitchen paper.
- Serve: Place fried eggs on top of the sandwiches (optional). Serve immediately with a fresh vinegary salad on the side for balance.
Notes
- Using the grill allows you to make several croques at once, perfect for feeding a crowd.
- For a vegetarian option, omit the ham and consider adding grilled vegetables.
- The Marmite adds a unique umami depth; adjust the quantity per your taste preference.
- Ensure the béchamel sauce is thick enough to coat the sandwiches well without running off.
- Serve immediately for the best texture, as the cheese and béchamel are at their peak when hot.
