Preparing the Baking Dish: Start by greasing a 9x13 inch baking dish. You can use cooking spray or butter to coat it well. This step helps prevent sticking. 2. Layering the Croissants: Next, take your six large croissants and tear them into bite-sized pieces. Spread these pieces evenly in the greased dish. This will be the base for your delicious casserole. 3. Adding Fillings: Now, sprinkle the diced cooked ham or turkey over the croissants. Follow that with the diced bell pepper and chopped spinach. Finally, add ¾ cup of shredded Gruyère cheese. This mix adds great flavor and texture. 4. Making the Egg Mixture: In a large bowl, crack six large eggs. Whisk them together with two cups of whole milk, one teaspoon of garlic powder, ½ teaspoon of salt, and ½ teaspoon of pepper. Don't forget to add one tablespoon of Dijon mustard. This mixture binds everything together and adds richness. 5. Combining Ingredients: Pour the egg mixture evenly over the layered croissants and fillings. Make sure every piece is soaked. This step is key for a moist casserole. 6. Topping with Cheese: Sprinkle the remaining ¼ cup of Gruyère cheese on top. This will create a lovely cheesy crust when baked. 7. Covering and Refrigerating: Cover the baking dish tightly with plastic wrap. Place it in the fridge overnight or for at least four hours. This allows the flavors to meld beautifully. 8. Baking Instructions: Preheat your oven to 350°F (175°C). Take the casserole out of the fridge and let it sit at room temperature for about 15 minutes. Bake it uncovered for 45-50 minutes. You want it set and golden brown on top. 9. Cooling and Serving Tips: Once baked, let the casserole cool for a few minutes before slicing. This helps it hold its shape. Garnish with fresh herbs like parsley or chives for a pop of color and flavor.

Aim for a light, airy texture, which will help the casserole rise nicely. - Choosing the Right Cheese Gruyère cheese works great for its meltiness and flavor. You can also try cheddar or mozzarella for a different taste. Choose a cheese that melts well to give your casserole a creamy texture. - Recommended Cooking Time Adjustments If your casserole is cold from the fridge, it may need extra cooking time. Check for a golden top and a firm center. If it’s still jiggly, bake for another 5-10 minutes. Always keep an eye on it to avoid burning. Pro Tips Use Day-Old Croissants: For the best texture, use croissants that are a day or two old. They will absorb the egg mixture better without becoming too soggy.

Both options add great flavor. Chicken offers a milder taste, while bacon brings a smoky crunch. Use about a cup of either, chopped into bite-sized pieces. Different Cheese Options Gruyère cheese is rich and creamy, but you can use other cheeses too. Cheddar adds a sharp flavor, while mozzarella gives a milder taste. Feta cheese can bring a tangy twist. Choose any cheese that will melt well and fit your taste. Vegetarian Version To make a vegetarian casserole, skip the meat entirely. You can pile on more veggies like mushrooms, zucchini, or broccoli. This adds color and nutrients without losing flavor. Make sure to use eggs and cheese to keep it hearty. Seasonal Vegetable Additions You can change the vegetables based on what’s in season. In spring, add asparagus or peas. In fall, try butternut squash or kale. Seasonal veggies not only taste better, but they also make the dish fresh and vibrant. Experiment to find your favorite mix! Refrigeration Tips After baking, let the casserole cool down. Cover it tightly with plastic wrap or foil. Store it in the fridge for up to 3 days. This keeps it fresh and tasty. Freezing Instructions You can freeze the casserole before baking.
