Ingredients:
- lb stale bread (Challah, Brioche, or White Bread), cubed into 1-inch pieces
- oz Canadian Bacon or smoked ham, chopped
- cup grated Swiss Cheese (or Gruyère), divided
- large Eggs
- cups Whole Milk
- cup Heavy Cream
- Tbsp Dijon Mustard
- Tbsp Fresh Lemon Juice
- tsp Worcestershire Sauce
- /2 tsp Freshly Ground Black Pepper
- /2 tsp Salt
- Tbsp Melted Unsalted Butter (for drizzling)
- Tbsp chopped Fresh Chives or Parsley (for garnish)
Instructions:
- Lightly grease a 9x13 inch baking dish. Toss the cubed bread pieces lightly with 1/3 of the grated Swiss cheese and spread evenly across the bottom.
- Distribute the chopped Canadian bacon or ham evenly over the bread layer. Sprinkle the remaining Swiss cheese on top.
- In a large bowl, vigorously whisk together the 12 eggs, milk, heavy cream, Dijon mustard, lemon juice, Worcestershire sauce, pepper, and salt until fully homogenous and slightly frothy.
- Slowly pour the entire custard mixture evenly over the bread and meat layers. Gently press down on the bread with a spatula to ensure everything is submerged.
- Cover the dish tightly with cling film and refrigerate for a minimum of 30 minutes, but preferably 2 to 4 hours or overnight, to allow the bread to fully absorb the liquid.
- Preheat your oven to 350°F (175°C). Remove the casserole from the fridge 20 minutes before baking to take the chill off slightly.
- Bake uncovered for 45–55 minutes. The casserole is done when the centre is set (no liquid jiggles when gently shaken) and the top is puffed and golden brown.
- Let the casserole rest for 5–10 minutes before slicing. Drizzle lightly with melted butter and garnish with fresh chives before serving.
