Ingredients You’ll Need

This recipe calls for simple yet carefully chosen ingredients that work wonderfully together to create layers of flavor and texture. Each component plays its part, from the tangy Marmite to the velvety béchamel and the lush cheeses that melt perfectly over crisp bread.

• 20g salted butter: the base for a smooth, rich béchamel sauce that adds creamy depth.
• 20g plain flour: thickens the béchamel to a luscious consistency.
• 250ml whole milk: brings richness and body to the sauce.
• ¼ nutmeg, finely grated: adds a subtle warmth and aromatic flair to the béchamel.
• 2 tsp Marmite (divided): delivers its signature savory umami punch—1 tsp in the sauce, 1 tsp spread on bread.
• 2 tbsp Dijon mustard: introduces a gentle tang that balances the richness.
• 250g Gruyère, grated (divided): 50g in the béchamel for creaminess, the rest melts beautifully on top for that golden crust.
• 50g cheddar, grated: adds sharpness and depth to the cheese mixture.
• 8 thick slices white bread: the perfect sturdy canvas to hold all the glorious fillings.
• 4 slices ham: bring a smoky, meaty element to each sandwich.
• 1 tbsp vegetable oil (optional): for frying the eggs to sunny perfection.
• 4 eggs (optional): crowns the sandwich with luscious, runny yolks for extra indulgence.
• Salad (vinegary, optional): provides a fresh, tangy contrast that brightens up the whole meal.

How to Make Croque Marmite Sandwich with Béchamel and Fried Eggs Recipe

Step 1: Prepare the Béchamel Sauce

Start by melting the salted butter in a pan over medium heat; once it foams, add the plain flour and constantly stir to form a smooth paste. Cooking this briefly removes the raw flour taste and sets the base for a creamy sauce.

Step 2: Gradually Add Milk

Pour in the whole milk slowly while stirring continuously to avoid lumps. Keep going until the béchamel thickens into a velvety sauce that will coat your sandwich beautifully.

Step 3: Flavor the Sauce

Bring in the magic by whisking in finely grated nutmeg, 1 teaspoon of Marmite, and Dijon mustard. These additions infuse the béchamel with a subtle kick of umami and warmth. Season lightly with black pepper and a pinch of salt to taste.

Step 4: Melt in the Cheeses

Remove your pan from the heat, then stir in 50g of Gruyère plus all the cheddar. The cheeses will melt perfectly, creating a rich, gooey sauce that’s the heart of this recipe.

Step 5: Toast the Bread Slices

Preheat your grill to high. Toast all the bread slices on one side under the grill for 2-3 minutes until golden and slightly crispy. Flip them over so the untoasted sides face up, preparing for the next flavorful layer.

Step 6: Add Marmite and Cheese

Spread the remaining teaspoon of Marmite evenly across the untoasted sides of the bread, then sprinkle over the reserved grated Gruyère. Pop the slices back under the grill just until the cheese melts and bubbles delightfully.

Step 7: Assemble the Sandwich

Place a slice of ham on half of the toasted bread. Cover each with a Marmite-cheese-topped slice to form sandwiches. Now, generously spread 3 to 4 tablespoons of your creamy béchamel sauce over the tops.

Step 8: Grill to Finish

Return the sandwiches to the grill for several minutes until the béchamel topping bubbles, turns golden, and develops a few irresistible charred spots—this step seals all those flavors with a gorgeous crust.

Step 9: Fry the Eggs

While the sandwiches grill, heat a tablespoon of vegetable oil in a small pan and fry your eggs to your preferred doneness. The runny yolks are a heavenly match for the savory layers below.

Step 10: Serve and Enjoy

Plate the sandwiches, topping each with a fried egg. Serve immediately with a bright, vinegary salad to cut through the richness and complete this show-stopping meal.

How to Serve Croque Marmite Sandwich with Béchamel and Fried Eggs Recipe

Garnishes

A sprinkle of freshly chopped parsley or chives can add a fresh herbal note that balances the intense flavors of the sandwich. A light dusting of ground black pepper over the fried eggs also elevates the taste.

Side Dishes

A crisp, vinegary green salad with mustard vinaigrette makes a perfect side, providing both color and a refreshing crunch. You might also enjoy simple roasted potatoes or a bowl of tomato soup for a comforting, hearty meal.

Creative Ways to Present

For a party or brunch gathering, consider cutting each sandwich diagonally into smaller triangles, perfect for sharing. Layering on a little more Marmite or swapping ham for smoked turkey can personalize your Croque Marmite Sandwich with Béchamel and Fried Eggs Recipe to suit different tastes.

Make Ahead and Storage

Storing Leftovers

You can store leftover sandwiches in an airtight container in the refrigerator for up to two days. To keep the béchamel from drying out, cover sandwiches tightly with cling film.

Freezing

Although best enjoyed fresh, the assembled sandwiches can be frozen before grilling for up to one month. Wrap them individually in foil or plastic wrap and thaw in the fridge overnight before finishing under the grill.

Reheating

To reheat, place sandwiches under a grill or in an oven at medium heat until warmed through and the béchamel is bubbly again. Avoid microwaving to preserve the texture and crispness.

FAQs

Can I make this recipe without eggs?

Absolutely! The fried eggs are optional and delicious, but the Croque Marmite Sandwich with Béchamel and Fried Eggs Recipe is just as satisfying without them.

Is Marmite necessary or can I substitute it?

Marmite is key to getting that distinctive umami flavor, but if you don’t have it, a little soy sauce or a miso paste can be used sparingly as alternatives.

What type of bread works best?

Thick slices of sturdy white bread hold up best to the wet béchamel and multiple toppings without becoming soggy, but a good quality sourdough or country loaf also works wonderfully.

Can I prepare the béchamel sauce in advance?

Yes, you can make the béchamel sauce a day ahead and refrigerate it. Reheat gently while stirring before using it to top the sandwiches.

How do I get the cheese to melt perfectly?

Grating the cheese finely ensures it melts evenly. Adding it off the heat for the béchamel prevents it from becoming stringy, giving a smooth and creamy finish.
