• 1 cup shredded Swiss cheese: Adds a creamy texture and nutty flavor that pairs well with the ham.
• 6 large eggs: Essential for binding the casserole together with a fluffy texture.
• 1 cup milk: Enhances the custard-like consistency, making it creamy and moist.

How to Make

1. Prepare the dish: Begin by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking dish lightly with butter or non-stick spray to prevent sticking.
2. Chop the croissants: Tear the croissants into bite-sized pieces and spread them evenly across the base of the greased baking dish. This ensures that every bite will have that incredible croissant texture.
3. Add the ham and cheese: Evenly distribute the diced ham and shredded Swiss cheese over the croissant pieces, creating delicious layers of flavor.
4. Whisk together the egg mixture: In a large bowl, whisk together the eggs, milk, salt, black pepper, and garlic powder until fully combined. Pour this mixture over the croissant, ham, and cheese layers, making sure to soak everything well.
5. Cover and chill: Cover the baking dish with plastic wrap and refrigerate it for at least 2 hours or overnight. This allows the croissants to absorb the egg mixture, enhancing the flavor and texture.
6. Bake: Remove from the refrigerator and uncover. Bake in the preheated oven for about 45 minutes, or until the center is set and the top is golden brown. Allow it to cool for about 10 minutes before serving.

Variations & Substitutions

Vegetable Option: To make a vegetarian version, replace the ham with sautéed spinach or diced bell peppers. This not only adds nutrition but also introduces vibrant colors to your dish.

Meat Alternatives: If you want to maximize flavor, try substituting ham with cooked bacon or sausage. This will give a different, yet equally savory twist to your casserole.

Cheese Choices: Feel free to experiment with other cheeses like cheddar or pepper jack for a spicy kick. Each cheese offers a unique flavor profile and complements the eggs beautifully.

Herbs and Spices: Enhance your casserole by adding chopped fresh herbs like chives or parsley into the egg mixture. They will impart a fresh and aromatic quality that elevates the dish.

Common Mistakes to Avoid

A few pitfalls can detract from your casserole experience. Overmixing the egg mixture can result in a rubbery texture. Be gentle when whisking. Not letting it sit long enough can lead to soggy croissants; allow adequate time for the custard to soak in overnight. Additionally, baking at too high a temperature can cause uneven cooking—always stick to the recommended baking temperature for consistent results.

Storage, Freezing & Reheating Tips

For any leftovers, store them in an airtight container in the refrigerator for up to 3 days. When reheating, microwave individual portions to keep them warm without drying out. If you wish to freeze, ensure it’s completely cooled, then wrap it tightly. It can last in the freezer for up to 3 months. To reheat from frozen, thaw overnight in the fridge and bake in the oven until heated through.
