Croque Madame Casserole Ingredients For the Casserole • Brioche – Provides a buttery, slightly sweet base that absorbs the béchamel sauce without becoming soggy. Substitution: Challah, French bread, or thick-cut white bread can be used. • Gruyère Cheese – Offers a nutty and creamy melt, essential for authentic flavor. Substitution: Emmental, Swiss cheese, or sharp white cheddar work well if Gruyère is unavailable. • Turkey Ham – Adds a savory element that complements the richness of the béchamel. Substitution: Sautéed mushrooms, spinach, or roasted bell peppers for a vegetarian option. • Eggs – Baked on top to add richness and a runny yolk, enhancing the overall texture. For the Béchamel Sauce • Butter – Essential for the béchamel sauce, providing richness that binds the ingredients together. • Flour – Used for thickening the béchamel sauce, creating a stable base for the casserole. • Milk – Forms the creamy béchamel sauce; whole milk is best for a rich flavor. • Dijon Mustard – Adds depth of flavor to the béchamel, elevating the overall dish. • Nutmeg – Provides warmth and a hint of spice in the béchamel, bringing everything together. Step‑by‑Step Instructions for Croque Madame Casserole Step 1: Preheat the Oven Begin by preheating your oven to 375°F (190°C). This temperature ensures your Croque Madame Casserole bakes evenly and develops that golden top. While the oven warms, gather your baking dish and set it aside, so you have everything ready for the next steps. Step 2: Make the Béchamel Sauce In a large saucepan, melt 4 tablespoons of butter over medium heat. Once melted, whisk in 4 tablespoons of flour, stirring continuously for about 2 minutes until you form a smooth roux. Gradually pour in 3 cups of milk while whisking until the mixture thickens, which should take about 5 minutes. Stir in 2 tablespoons of Dijon mustard and a pinch of nutmeg for a delightful flavor boost. Step 3: Layer the Casserole In your greased baking dish, arrange slices of slightly stale brioche to cover the bottom entirely. Pour half of the creamy béchamel sauce over the bread, ensuring even coverage. Then, sprinkle generously with 2 cups of shredded Gruyère cheese and layer 1 cup of turkey ham, or your preferred substitute, for added heartiness. Step 4: Add More Layers Repeat the layering process with the remaining brioche, followed by the rest of the béchamel sauce, ensuring the bread is fully saturated. Finish this layer with another generous sprinkle of Gruyère cheese on top. This will form a delectable crust as your Croque Madame Casserole bakes. Step 5: Prepare for Baking Allow the assembled casserole to sit for about 15 minutes at room temperature. This resting time helps the bread absorb the béchamel sauce before baking, yielding a rich texture. Meanwhile, you can crack 4 to 6 eggs on top of the casserole, spacing them evenly for an inviting presentation. Step 6: Bake the Casserole Transfer the baking dish to the preheated oven. Bake for 25-30 minutes, or until the top is beautifully golden-brown and the egg whites are set, while the yolks remain runny. Keep an eye on it in the last few minutes to prevent overbaking, ensuring that your Croque Madame Casserole is just perfect. Step 7: Serve and Savor Once out of the oven, let the casserole rest for about 5 minutes before slicing. This brief cooling period makes it easier to serve. Feel free to garnish with fresh herbs for an extra touch, and enjoy this delicious comfort food with family or friends!

Croque Madame Casserole Recipe FAQs How do I choose the right brioche for my Croque Madame Casserole? Absolutely! Look for brioche that is slightly stale, as it holds up better in the béchamel sauce without turning soggy. If your brioche is fresh, lightly toast it beforehand to ensure it absorbs the sauce perfectly. You can also opt for Challah or thick-cut white bread if necessary. How should I store any leftovers from the Croque Madame Casserole? For sure! Store any leftovers in an airtight container in the refrigerator for up to 3 days. When you’re ready to enjoy it again, gently reheat in the oven at 350°F (175°C) until warmed through, being mindful to keep the eggs intact. Can I freeze my Croque Madame Casserole? How? Yes, you can! To freeze, wrap individual portions tightly in plastic wrap, followed by foil, and store them for up to 2 months. When you’re ready to enjoy, thaw in the refrigerator overnight. To reheat, place the frozen casserole in a baking dish covered with foil and bake at 350°F (175°C) for about 30–40 minutes or until thoroughly heated. What if I have dietary restrictions or allergies? Very good question! If you’re looking to adapt the recipe, you can use gluten-free bread to accommodate gluten sensitivities.
