Step-by-Step Instructions

Preheat Oven and Prepare Baking Dish

First, you need to preheat your oven to 350°F (175°C). This step is important for even cooking. Next, grease a 9×13-inch baking dish. Use butter or cooking spray to ensure the casserole does not stick.

Combine Ingredients

In a large bowl, combine the torn croissant pieces, diced ham, and both shredded cheeses. Make sure to mix gently. You want each piece to be coated but not squished. This combination creates layers of flavor in every bite.

Prepare Egg Mixture

In another bowl, whisk together the eggs and milk. Add in the Dijon mustard, garlic powder, onion powder, salt, and pepper. Whisk until everything is well blended. This egg mixture binds everything together and adds richness.

Assemble Casserole

Pour the egg mixture over the croissant and ham mixture. Make sure to cover everything evenly. Let the mixture sit for about 10-15 minutes. This waiting time allows the croissants to soak up the egg mixture.

Baking the Casserole

Transfer the soaked mixture into the greased baking dish. Spread it out evenly to ensure it bakes well. Bake in the preheated oven for 35-40 minutes. Check for doneness by looking for a puffed and golden top. The casserole should feel set but still soft in the center.

Tips & Tricks

Best Serving Suggestions

Serve your ham and cheese croissant casserole warm. It tastes best right out of the oven. Pair it with a fresh salad or mixed greens. This adds a nice crunch and balances the dish. For a pretty presentation, cut the casserole into squares. Place each square on a plate and sprinkle with chopped parsley. This adds color and freshness.

Customization Ideas

Feel free to mix things up! Use different cheeses like Swiss or pepper jack for a twist. You can also swap the ham with turkey or chicken. For extra nutrition, add veggies. Spinach, bell peppers, or mushrooms work great. They add flavor and color to the dish.

Baking Tips

To check if your casserole is done, look for a puffed and golden top. It should be firm but not dry. A toothpick inserted in the center should come out clean. To avoid a soggy bottom, make sure to let the casserole sit for a bit before baking. This helps absorb the egg mixture well. Also, don’t skip the soaking time; it is key for great texture.

Variations

Vegetarian Option

You can easily make a vegetarian version of this dish. Instead of ham, use fresh spinach or sautéed mushrooms. Both options add great flavor and nutrition. Spinach adds a nice green touch, while mushrooms give a hearty feel. Just sauté them lightly before mixing into the casserole. This swap keeps the dish filling and tasty.

Gluten-Free Version

For a gluten-free option, pick gluten-free croissants or bread. Many brands offer tasty choices that work well in this recipe. Be sure to check the labels for any hidden gluten. This small change ensures everyone can enjoy this delicious dish without worry.

Different Cheese Combinations

Cheese is the star of this dish. While cheddar and mozzarella are classics, you can explore other options. Try Swiss cheese for a nutty flavor or pepper jack for a spicy kick. Mixing cheeses can create a unique twist on the classic recipe. Don’t be afraid to experiment with your favorites!

Storage Info

Storing Leftovers

To keep your ham and cheese croissant casserole fresh, follow these steps. First, let the casserole cool completely. This helps prevent condensation. Next, place leftovers in an airtight container. Glass or plastic containers with tight lids work best. You can store it in the fridge for up to three days. Make sure to label the container with the date.

Reheating Instructions

When it’s time to enjoy your leftovers, reheating is simple. For the best results, use the oven. Preheat it to 350°F (175°C). Cut the casserole into squares and place them in a baking dish. Cover with foil to keep moisture in. Heat for about 15-20 minutes. If you prefer the microwave, place a square on a microwave-safe plate. Heat for 1-2 minutes, checking to see if it’s warm throughout.

Freezing Tips

If you want to save some for later, freezing works great. Cut the casserole into portions before freezing. Wrap each piece in plastic wrap, then place them in a freezer bag. Remove as much air as possible. Label the bag with the date. You can freeze it for up to three months. To defrost, place it in the fridge overnight. Reheat it as mentioned earlier for a tasty meal.
