Step‑by‑Step Instructions for Croque Madame Breakfast Casserole
Step 1: Bread Preparation
Begin by cubing the thick country French bread into bite-sized pieces and placing them in a large mixing bowl. This will create a sturdy base for your Croque Madame Breakfast Casserole. Aim for about 8 cups of bread, and let it sit while you prep the other ingredients—this allows the bread to dry slightly, enhancing texture.
Step 2: Whisk Ingredients
In a separate mixing bowl, whisk together Pete and Gerry’s organic eggs, milk, a pinch of black pepper, and optional thyme. This fragrant mixture will bind your casserole beautifully. Set this egg mixture aside for about 5 minutes, allowing the flavors to meld while you prepare for soaking the bread.
Step 3: Soak the Bread
Pour the egg mixture evenly over the cubed bread in the large bowl, gently folding it together to ensure the bread absorbs all the liquid. Let it soak for at least 15 minutes at room temperature, allowing the bread to become fully saturated and flavorful. Stir occasionally to encourage even soaking.
Step 4: Layering Ingredients
Preheat your oven to 350°F (175°C). Grease a casserole dish with butter or oil to prevent sticking. Spread half of the soaked bread mixture into the bottom of the dish. Layer on slices of smoked ham and sprinkle generously with grated Gruyere cheese, providing a rich, melty flavor throughout your Croque Madame Breakfast Casserole.
Step 5: Pour Béchamel Sauce
Prepare a creamy béchamel sauce by melting butter in a saucepan, whisking in flour until golden, then gradually adding milk until thickened. Pour this silky sauce evenly over the layered bread and ham in your casserole dish. To enhance the dish, add a few extra egg yolks on top before finishing.
Step 6: Bake and Broil
Cover the casserole dish with aluminum foil to prevent excessive browning, and place it in the preheated oven. Bake for 45–50 minutes, or until the center is set and a knife inserted comes out clean. Remove the foil during the last 5–10 minutes and broil for 2-3 minutes to achieve a beautifully crispy and golden top.
Step 7: Serve and Garnish
Once out of the oven, allow the Croque Madame Breakfast Casserole to rest for about 10 minutes to firm up. Just before serving, garnish generously with fresh thyme and a dash of black pepper. Serve warm and enjoy this comforting dish that brings warmth and joy to your breakfast table!
