Ingredients for Baked Croque Monsieur

  • White Bread
  • Cheddar Cheese
  • 8 ounces thinly sliced deli ham
  • 1/2 medium yellow onion, thinly sliced
  • 6 large eggs
  • 1 cup whole milk
  • Herbs
  • Salt
  • Panko Breadcrumbs
  • 2 tablespoons melted butter

How to Make Baked Croque Monsieur

  1. Preheat oven to 400°F (200°C). Grease a 9x13 inch baking pan.
  2. Remove crusts from 1 loaf (about 1 pound) of bread, if desired. Cut bread into slices to fit the pan, creating an even bottom layer.
  3. Sprinkle half (about 4 ounces) of the grated Gruyère cheese over the bread.
  4. Layer 8 ounces thinly sliced deli ham over the cheese.
  5. Thinly slice 1/2 medium yellow onion and distribute evenly over the ham.
  6. Top with remaining 4 ounces of Gruyère cheese.
  7. Arrange the remaining bread slices on top of the cheese, creating a second layer.
  8. Gently press down on the bread to compact the layers.
  9. In a medium bowl, whisk together 6 large eggs, 1 cup whole milk, 1/2 teaspoon salt, and 1/4 teaspoon black pepper.
  10. Slowly pour the egg mixture evenly over the bread, ensuring all layers are moistened.
  11. Cover the baking pan and refrigerate for at least 2 hours, or preferably overnight.
  12. In a small bowl, combine 1/2 cup panko breadcrumbs, 2 tablespoons melted butter, and 1 tablespoon grated Parmesan cheese.
  13. Sprinkle the breadcrumb mixture evenly over the casserole.
  14. Bake for 42-48 minutes, or until the top is golden brown and the custard is set. The internal temperature should reach 160°F (71°C).
  15. Let the casserole rest for 10 minutes before cutting and serving. Enjoy!

Chef's Tip for Extra Flavor

Elevate your dish with simple flavor boosters! A final flourish of freshly chopped herbs can add incredible brightness, while a squeeze of lemon or lime juice right before serving can awaken all the flavors. Don't underestimate a sprinkle of quality finishing salt or a drizzle of good olive oil to make your creation shine.
