Ham and Cheese Croissant Breakfast Casserole Ingredients
For the Casserole
• Croissants – The buttery base that lends a flaky texture; opt for fresh, medium-sized croissants for the best results.
• Eggs – Essential for creating a rich, custard-like filling; large eggs are recommended for optimal flavor.
• Half and Half (or Whole Milk) – Provides creaminess; substitute with whole milk if you want a lighter option.
• Dijon Mustard – Adds a lovely tang; this ingredient is recommended for an authentic ham and cheese flavor.
• Salt – Helps to balance and enhance the flavors; use a pinch to taste.
• Ham – Adds a savory and hearty element; approximately 6 thin slices of deli or leftover ham work best.
• Swiss or Gruyere Cheese – Melts beautifully, creating a creamy texture; freshly shredded is ideal for optimal melting.
• Powdered Sugar – Dust over the casserole just before serving for a touch of sweetness that beautifully contrasts the savory ingredients.
Step‑by‑Step Instructions for Ham and Cheese Croissant Breakfast Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures that the Ham and Cheese Croissant Breakfast Casserole bakes evenly and develops a delightful golden crust. Preheating is essential for achieving that perfect texture, so don’t skip this step.
Step 2: Prepare the Baking Dish
Lightly coat a 9×6 or 9×11 inch deep baking dish with cooking spray to prevent sticking. This step is crucial for easy removal once the casserole is baked. Being thorough ensures your delicious creation will come out easily and maintain its appealing presentation.
Step 3: Arrange the Croissants
Tear your fresh croissants in half and arrange them cut-side up in the prepared dish. For an even distribution, nestle the croissants closely together. Cut the ham into thirds and intersperse it among the croissants, ensuring each piece is surrounded by that buttery goodness for optimal flavor.
Step 4: Add the Cheese
Sprinkle the freshly shredded Swiss or Gruyere cheese evenly over the croissants and ham. The cheese will melt beautifully during baking, creating that gooey texture we all adore. Make sure to cover every croissant to ensure that each bite is packed with cheesy goodness.
Step 5: Combine the Egg Mixture
In a medium bowl, whisk together the eggs, half and half, Dijon mustard, and a pinch of salt until well-combined and frothy. This mixture adds a rich custard-like filling to your casserole. Pour this egg mixture evenly over the layered croissants and ham, making sure to soak them thoroughly.
Step 6: Refrigerate the Casserole
Cover the dish with foil and refrigerate for at least 30 minutes, or up to overnight for the best flavor absorption. This soaking time allows the croissants to absorb the egg mixture, creating a moist and flavorful breakfast casserole.
Step 7: Bake the Casserole
Once your casserole has soaked, bake it covered with foil for 20 minutes. This initial cooking will set the eggs. After this, remove the foil and continue baking for an additional 10-15 minutes until the casserole is hot and bubbly, with a golden-brown top.
Step 8: Rest and Serve
After removing the casserole from the oven, let it rest for 5 minutes to allow the flavors to settle. As a final touch, dust the top with powdered sugar just before serving. This adds a sweet contrast to the savory layers of your Ham and Cheese Croissant Breakfast Casserole.
