Lay five of the bread slices on a board. Spread over the butter and mustard. Next, divide the ham among the bread slices and finish by laying another piece of bread on top of each stack. Cut the sandwiches into quarters on the diagonal.
Step 2
Arrange the triangles in a not-too-deep 23cm x 23cm x 7.5cm (9in x 9in x 3in) ovenproof serving dish. In a large jug, mix together the milk, cream, eggs and plenty of seasoning until well combined. Pour the egg mixture evenly over the bread, then press the bread down a little. Leave to soak in the fridge for 15min, if you have time, otherwise carry straight on.
Step 3
Preheat oven to 180°C (160°C fan) mark 4. Scatter over the cheese and season with freshly ground black pepper. Cook for 30-35min until the egg mixture has set. Serve immediately with a crisp green salad.
An experienced and highly skilled team of food writers, stylists and digital content producers, the Good Housekeeping Cookery Team is a close-knit squad of food obsessives. Cookery Editor Emma Franklin is our resident chilli obsessive and barbecue expert, who spends an inordinate amount of time on holidays poking round the local supermarkets seeking out new and exciting foods. Senior Cookery Writer Alice Shields is a former pastry chef and baking fanatic who loves making bread and would have peanut butter with everything if she could. Her favourite carb is pasta, and our vibrant green spaghetti is her weeknight go-to. Lover of all things savoury, Senior Cookery Writer Grace Evans can be found eating crispy corn and nocellara olives at every opportunity, and will take the cheeseboard over dessert any time (though she cannot resist a slice of tres leches cake). With a wealth of professional kitchen know-how, culinary training and years of experience between them, they are all dedicated to ensuring every Good Housekeeping recipe is the best it can be, so you can trust they’ll work (and if they don’t – we’ll have the answer for why*) every time (*90% of the time the answer is: “buy an separate oven thermometer”!).
