Step‑by‑Step Instructions for Ham and Cheese Croissant Breakfast Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). While the oven warms up, grab a 9x13-inch baking dish and generously grease it with nonstick spray. This will ensure an easy release of your delectable Ham and Cheese Croissant Breakfast Casserole once it’s baked to perfection.
Step 2: Prepare the Croissants
Take your day-old croissants and cut them into bite-sized pieces, aiming for about 1-inch chunks. Layer these evenly across the bottom of the greased baking dish, filling it as much as possible. The delightful buttery texture of the croissants will serve as a wonderful base, soaking up the egg mixture beautifully.
Step 3: Layer the Ham and Cheese
Now, sprinkle the diced ham evenly over the croissant layer, ensuring each piece gets a touch of savory goodness. Next, follow with a generous layer of shredded Swiss cheese and then shredded cheddar cheese. The combination of these two cheeses will create a mouthwatering, gooey texture in your Ham and Cheese Croissant Breakfast Casserole.
Step 4: Whisk the Custard Mixture
In a mixing bowl, crack the large eggs and whisk them until frothy. Gradually blend in the whole milk or half-and-half, Dijon mustard, salt, and pepper. Whisk the mixture until smooth and creamy, ensuring the flavors are well combined. This custard will bind the casserole together and add richness to each bite.
Step 5: Combine and Soak
Pour the whisked egg mixture evenly over the layered croissants, ham, and cheese. Gently press down on the croissants to help them absorb the custard. Allow the casserole to sit for 15 minutes so the croissants soak up that divine mixture, ensuring a moist and flavorful result when baked.
Step 6: Bake in the Oven
Place the baking dish in your preheated oven and bake the Ham and Cheese Croissant Breakfast Casserole for 30-35 minutes. Keep an eye out for a golden-brown top and bubbling edges; this visual cue indicates your casserole is nearly ready to be enjoyed. The aroma will surely fill your kitchen with warmth!
Step 7: Cool and Serve
Once baked, carefully remove the casserole from the oven and let it cool for at least 5-10 minutes. This resting time allows the flavors to meld and makes serving easier. Slice into squares and serve warm, reveling in the comforting flavors of your delightful Ham and Cheese Croissant Breakfast Casserole!

Ham and Cheese Croissant Breakfast Casserole Recipe FAQs
What type of croissants should I use for the casserole?
Using day-old croissants is ideal for the Ham and Cheese Croissant Breakfast Casserole as they are a bit stale, allowing them to soak up the egg mixture better without becoming too mushy. Fresh croissants can work as well, but they may not provide the same texture experience.
How should I store leftovers from the casserole?
Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days. When you're ready to enjoy it again, simply reheat individual portions in the microwave or place slices in the oven until heated through.

What should I do if my casserole doesn’t set properly?
If you find that your casserole didn’t set or is too runny, it’s likely that it didn't soak long enough in the egg mixture or the oven temperature wasn't high enough. For future attempts, make sure to press down gently on the croissants after combining with the custard and let it sit for at least 15 minutes. If baking from cold, remember to increase the baking time by about 5-10 minutes to ensure thorough cooking.
Can I make this dish vegetarian or accommodate specific dietary needs?
Yes, you can make the Ham and Cheese Croissant Breakfast Casserole vegetarian by simply omitting the ham and adding extra veggies like spinach, bell peppers, or mushrooms.
