Ingredients
Here’s what you’ll need to make this indulgent and halal-friendly Croque Monsieur Breakfast Casserole:
- 8 slices of halal bread (such as white, whole wheat, or brioche)
- 2 tablespoons unsalted butter
- 1 ½ cups shredded Gruyère cheese (or a mild Swiss cheese, Halal-certified)
- 1 cup shredded cheddar cheese
- 1 ½ cups halal ham (sliced or diced)

- 1 ½ cups milk (dairy or plant-based)

Step-by-Step
InstructionsFollow these easy-to-follow steps to create the ultimate Croque Monsieur Breakfast Casserole:
Prepare the Casserole:
- Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or casserole pan with butter or cooking spray, or line it with parchment paper for easy removal after baking.
- Prepare the Bread: If using a loaf of bread, cut it into thick slices (about 1-inch thick). Lightly toast the bread slices in a toaster or under a broiler to ensure they hold up well in the casserole. Lay the slices of bread in an even layer at the bottom of the prepared casserole dish, cutting the bread to fit if necessary.
- Cook the Ham: If you’re using whole slices of halal ham, chop them into bite-sized pieces. For extra flavor, sauté the ham in a little butter or olive oil for a couple of minutes until slightly crispy and caramelized. Spread the cooked ham evenly over the bread slices in the casserole dish.
- Layer the Cheese: Sprinkle half of the shredded Gruyère cheese and half of the shredded cheddar cheese over the ham and bread layers.
Make the Custard:
- Whisk the Eggs: In a large mixing bowl, whisk the eggs, milk, Dijon mustard, garlic powder, salt, and black pepper together until smooth. Make sure the eggs are fully incorporated into the milk to create a creamy custard base for the casserole.
- Pour the Custard Over the Bread: Pour the egg and milk mixture over the bread, ham, and cheese layers, making sure that all of the bread is soaked with the custard. Press the bread gently down into the custard mixture to help it absorb the liquid evenly.
- Top with Cheese: Sprinkle the remaining half of the Gruyère and cheddar cheese over the top of the casserole. This will create a deliciously cheesy, golden crust once baked.
Bake the Casserole:
- Bake: Place the casserole in the preheated oven and bake for 45-50 minutes or until the top is golden brown, bubbly, and the custard is set. To check for doneness, gently shake the pan; the casserole should not jiggle. You can also insert a toothpick or knife into the center of the casserole—if it comes out clean, it’s ready!
- Cool Slightly: Once baked, remove the casserole from the oven and let it cool for 5-10 minutes before serving. This will make it easier to cut into neat squares or slices.
Serve the Casserole:
- Garnish and Serve: Serve the Croque Monsieur Breakfast Casserole warm, garnished with a sprinkle of chopped fresh parsley and a dash of dried thyme if desired. This casserole pairs beautifully with a fresh salad or some roasted vegetables for a complete meal.

How to Serve Croque Monsieur Breakfast Casserole
The Croque Monsieur Breakfast Casserole is a versatile dish that can be served in several delicious ways:
- For Brunch: Serve the casserole as the centerpiece of a brunch spread, alongside fresh fruit, pastries, and a light salad.
- With Eggs: Pair with scrambled eggs or a soft-boiled egg for a more substantial meal.
- With Fresh Greens: Serve with a side of sautéed spinach, arugula, or a mixed greens salad dressed with a light vinaigrette to balance the richness of the casserole.

Additional Tips for Croque Monsieur Breakfast Casserole
Here are some tips to make your Croque Monsieur Breakfast Casserole even better:
- Use Day-Old Bread: Stale bread works best for casseroles because it soaks up the custard without getting too soggy. If your bread is fresh, let it sit out for a few hours to firm up before using.
- Chill Before Baking: For even better flavor, assemble the casserole the night before and let it sit in the fridge overnight. This allows the flavors to meld together and makes the baking process faster the next morning.
- Customize the Cheese: While Gruyère is traditional, feel free to experiment with other cheeses like mozzarella, fontina, or even a sharp cheddar to add different textures and flavors.
- Add Vegetables: Add sautéed mushrooms, spinach, or even roasted bell peppers to the casserole for a veggie-packed version.
- Make It Gluten-Free: Substitute the bread with gluten-free bread to make the casserole gluten-free.
