Step‑by‑Step Instructions for Croque Madame Breakfast Casserole
Step 1: Prepare the Bread
Begin by cutting the thick country-style French bread into 1-inch cubes, ensuring a sturdy base that will absorb the egg mixture beautifully. Set the bread cubes aside in a large mixing bowl while you gather the other ingredients, allowing them to breathe and prepare for their delicious journey ahead.
Step 2: Make the Egg Mixture
In a separate large mixing bowl, whisk together 6 Pete and Gerry’s organic eggs, 2 cups of milk, and a pinch of salt until fully blended and frothy. This mixture will serve as the binding agent for your Croque Madame Breakfast Casserole, creating a creamy and rich texture that will elevate every bite.
Step 3: Combine Ingredients
Carefully add the cubed bread to the egg mixture, gently stirring until every piece is well-coated and saturated. Allow this mixture to sit for at least 30 minutes, letting the bread soak up all those delightful flavors, resulting in a moist casserole that’s bursting with goodness.
Step 4: Layer the Casserole
Grease a medium-sized casserole dish with butter or cooking spray for easy removal. Begin layering by placing half of the soaked bread mixture at the bottom, followed by slices of smoked ham and half of the Gruyere cheese. Pour half of the creamy bechamel sauce on top, ensuring an even distribution of flavors.
Step 5: Add Second Layer
Next, repeat the layering process with the remaining bread mixture, finishing with the rest of the ham, Gruyere cheese, and the remaining bechamel sauce. This builds height and creates that decadent, melty top layer that is signature to the Croque Madame Breakfast Casserole.
Step 6: Add Toppings
If desired, crack additional eggs on top of the casserole for an extra touch of indulgence. Sprinkle with dried thyme and freshly cracked black pepper, which will infuse the dish with warmth and aroma as it bakes, ensuring a flavorful experience in every bite.
Step 7: Bake
Cover the casserole dish with foil and bake in a preheated oven at 350°F (175°C) for 30 minutes. After this time, carefully remove the foil, allowing the casserole to continue baking for an additional 10 minutes or until the top is golden brown and bubbling with molten cheese.
Step 8: Finish and Serve
Once baked, let the Croque Madame Breakfast Casserole cool for about 10 minutes before slicing. Garnish with fresh thyme and an extra sprinkle of black pepper to enhance its presentation. Serve warm, allowing your guests to enjoy this hearty and comforting dish filled with delightful flavors!
