For the Casserole

  • Deli Ham (Black Forest) – Provides savory flavor and protein; can substitute with turkey or a different deli meat.
  • Shredded Swiss Cheese – Offers a creamy texture and mild tang; cheddar can be used for a stronger flavor.
  • Large Eggs – Binds the casserole and contributes to the custard-like base; substitutable with flax eggs for a vegan version.
  • Half and Half – Adds richness to the egg mixture; milk or a non-dairy milk can be used as a lighter option.
  • Salt – Enhances flavors; adjust to preference or dietary needs.
  • Mustard Powder – Adds depth and a slight tang; omit for a milder flavor.
  • Garlic Powder – Supplies a hint of aroma and flavor; fresh garlic can be used for more potency.
  • White Ground Pepper – Provides subtle heat and flavor; black pepper can be substituted for a similar effect.
  • Maple Syrup – Sweetens the dish and balances the savory elements; honey or agave syrup are suitable alternatives.

How to Make Ham and Cheese Breakfast Casserole

  1. Prep Ingredients: Start by cubing the croissants into bite-sized pieces and chopping the ham. In a large bowl, combine them with the shredded cheese to set the flavorful base for your casserole.

  2. Mix Egg Mixture: In a separate bowl, beat the eggs with the half and half, maple syrup, salt, mustard powder, garlic powder, and white pepper. Mix until everything is well combined and the texture is uniform.

  3. Combine: Pour the egg mixture over the croissant and ham mixture, ensuring all pieces are soaked well. Allow it to sit for at least 20 minutes—this step helps the croissants absorb the egg goodness.

  4. Preheat Oven: Set your oven to 350°F (175°C) so it’s hot and ready for baking after your casserole has soaked.

  5. Bake: Cover the casserole dish with aluminum foil and bake it for 20 minutes. Then, remove the foil, rotate the pan, and bake for another 20-25 minutes. Look for a golden-brown top and ensure the eggs are fully set.

  6. Serve: Dust the top with powdered sugar just before serving for that sweet touch. Pair it with raspberry jam and additional maple syrup for an extra layer of sweetness.

Optional: Garnish with fresh berries for an inviting touch.

Ham and Cheese Breakfast Casserole Using Croissants Recipe FAQs

What type of croissants are best for this casserole?
Absolutely! I recommend using stale or day-old croissants for the best results. They absorb the egg mixture well, providing that delightful softness without becoming overly soggy. Fresh croissants can also be used, but drying them out slightly by leaving them out for a few hours helps enhance their texture.

How should I store leftovers from the Ham and Cheese Breakfast Casserole?
You can store leftovers in an airtight container in the refrigerator for up to 3 days. Make sure it’s completely cooled before sealing to maintain its freshness. For the best flavor and texture, reheat individual portions in the oven at 350°F (175°C) for about 15-20 minutes until thoroughly warmed.

Can I freeze the casserole?
Definitely! This casserole freezes beautifully. Wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn, and it can last up to 2 months. When you’re ready to enjoy it, just thaw it in the fridge overnight, then reheat in the oven.

What if the casserole is too soggy after baking?
If your casserole turns out soggy, a common culprit is too much egg mixture or not letting the croissants soak long enough. To remedy a soggy casserole, ensure you stick to the listed measurements, and it’s best to let it rest for at least 20 minutes before baking. For a crisper end result, you can also bake it a bit longer or broil for a few minutes at the end while keeping a watchful eye.

Is this casserole suitable for someone with dietary restrictions?
Very! If you have dietary concerns, there are simple substitutions to make this casserole fit your needs. Use flax eggs instead of regular eggs for a vegan option. Substitute deli ham with turkey or omit the meat altogether for a vegetarian twist. For dairy-free needs, opt for a non-dairy milk instead of half and half, and a non-dairy cheese can also work if desired.

How can I enhance this casserole with additional flavors?
You can easily customize your Ham and Cheese Breakfast Casserole with various veggies or spices. Adding chopped spinach or bell peppers can enhance nutrition and taste. If you like a bit of heat, toss in jalapeños or sprinkle some cayenne pepper into the egg mixture for an added kick that elevates the flavors!
