Ingredients
Scale
Sandwich Ingredients
- 1 loaf specialty bread, such as Franz Innkeeper’s Cranberry Orange Bread (or what’s in season)
- 16 oz Canadian bacon or ham slices
- 4 oz Swiss cheese, sliced
- ¼ cup honey mustard
- ½ cup orange cranberry relish or ½ cup favorite preserves like peach marmalade or raspberry jam
Custard and Topping Ingredients
- 1 ½ cups shredded Gruyere cheese
- 1 ¾ cups milk
- 8 large eggs
- 1 tsp kosher salt
- ½ tsp fresh ground pepper
- Powdered sugar for dusting
- ¾ cup raspberry preserves (optional, for serving)
- Fresh sage, for garnish
Instructions
- Prepare the baking dish: Spray a 13×9 inch baking dish evenly with cooking spray to prevent sticking.
- Assemble the sandwiches: On a large surface, lay out the slices of bread. On half of the slices, arrange the Canadian bacon or ham, then layer with sliced Swiss cheese. Spread 1 tablespoon of orange cranberry relish or raspberry jam over the cheese.
- Spread honey mustard: On the remaining bread slices, generously spread the honey mustard. The generous amount is important to enhance the flavor.
- Create sandwiches: Place the bread slices together to form sandwiches, then cut each sandwich into triangles.
- Arrange in the baking dish: Place the triangle sandwiches in the prepared pan with points facing upwards, pushing them close together to fit well in the dish.
- Mix custard: In a large bowl, whisk together the eggs, milk, kosher salt, and fresh ground pepper until fully combined.
- Pour custard and add cheese: Pour the egg mixture over the arranged sandwiches in the baking dish, then sprinkle the shredded Gruyere cheese evenly on top.
- Chill overnight: Cover the dish and refrigerate overnight to allow the bread to soak in the custard mixture.
- Bake the casserole: Preheat your oven to 350°F (175°C). Remove the cover and bake uncovered for 30-35 minutes, or until the casserole is golden brown and the eggs are set but not runny.
- Cool and garnish: Remove the casserole from the oven and let it cool for 10 minutes. Garnish with fresh sage sprigs and dust with powdered sugar.
- Serve: Serve warm with optional sides of raspberry preserves or maple syrup to complement the sweet and savory flavors. Makes about 8 servings.
Notes
- This casserole can be made ahead and refrigerated for up to 2 days before baking, making it convenient for busy mornings or entertaining.
- Feel free to serve with your favorite preserves or maple syrup for added sweetness.
- Using specialty bread like cranberry orange adds a unique flavor, but any hearty bread can be substituted.
- Adjust the amount of honey mustard and preserves to your taste to balance the sweet and savory elements.
- Make sure to bake until the eggs are fully set to avoid a runny texture.
