1-First Step: Prep Your Dish and Ingredients Begin by preheating your oven to 350°F and greasing a 9 x 13 inch casserole dish to prevent sticking. Cut the 5-6 large croissants into 1-inch cubes and spread them evenly in the dish. This step sets the foundation, allowing the croissants to absorb flavors while you mix the rest, and it’s a great way to adapt for dietary needs like using gluten-free croissants.

2-Second Step: Whisk the Egg Mixture In a large bowl, whisk together the 7 large eggs, 1/2 cup 2% milk, 1 tsp garlic powder, 1/4 tsp ground mustard, 1/2 tsp salt, and 1/2 tsp black pepper. This creates a savory custard that soaks into the croissants, enhancing the Ham And Cheese Croissant Casserole’s texture. For variations, you could use whole milk if you prefer a richer version, keeping it versatile for different tastes.

3-Third Step: Assemble the Casserole Pour the egg mixture over the cubed croissants in the dish, making sure everything is well-coated. Evenly distribute the 1/2 lbs cubed ham, 1 cup shredded cheddar, and 1 cup shredded mozzarella on top. This layering ensures each bite has a mix of flavors, and you can tweak it for low-calorie options by choosing leaner ham.

4-Fourth Step: Bake to Perfection Cover the dish and bake for 20 minutes, then uncover and bake for another 20 minutes until it’s golden and set. The total bake time is about 40 minutes, resulting in a bubbly, cheesy top that’s irresistible. If you’re preparing ahead, remember this Ham And Cheese Croissant Casserole can sit in the fridge for up to 24 hours, which might add a few minutes to baking if it’s cold.

5-Fifth Step: Add the Finishing Touch Once out of the oven, garnish with 1-2 tbsp chopped parsley for a fresh pop of color and flavor. Let it cool for a few minutes before serving to eight people. This final step makes your Ham And Cheese Croissant Casserole not just tasty but also visually appealing for family meals or gatherings.
