This Ham and Cheese Croissant Casserole is a tasty breakfast treat that’s super easy to whip up. Flaky croissants, savory ham, and gooey cheese create a warm, cozy dish!
I love how simple it is to put together. You just mix, pour, and bake—perfect for a weekend brunch! It’s a crowd-pleaser, and I always sneak an extra piece for myself! 😄
Key Ingredients & Substitutions
Croissants: The flaky texture of croissants is essential for this casserole. If you’re in a pinch, you can substitute with store-bought puff pastry or even soft bread like brioche for similar results.
Ham: You can use any cooked ham, such as leftover holiday ham or deli meat. If you’re looking for a lighter option, turkey ham or even cooked bacon works great too!
Cheese: Cheddar is a classic choice, but feel free to mix in Swiss, mozzarella, or even pepper jack for a kick. I often like to grate my cheese fresh for better meltability!
Milk: Whole milk gives a rich flavor, but you can substitute with 2% or even dairy alternatives like almond or oat milk for a lighter dish.
Dijon Mustard: This adds a nice depth of flavor. If you’re not a fan, you can skip it or use a touch of yellow mustard instead.
How Do I Make Sure My Casserole is Perfectly Set?
Getting the casserole set properly is key for a good texture. Here’s how to ensure success:
- Letting the casserole sit for 15-20 minutes before baking is crucial. This allows the croissants to absorb the egg mixture, ensuring it cooks evenly.
- Bake until the top is golden brown and a knife inserted comes out clean. It should be firm in the middle, not jiggly!
- If you notice the top browning too quickly, you can cover it loosely with aluminum foil during baking.
Ham And Cheese Croissant Casserole
Ingredients:
- 6 large croissants, torn into bite-sized pieces
- 1 cup cooked ham, diced or sliced
- 2 cups shredded cheddar cheese (or a mix of cheddar and Swiss)
- 6 large eggs
- 2 cups milk (whole or 2%)
- 1 tsp Dijon mustard (optional)
- 1/2 tsp salt
- 1/4 tsp black pepper
- 1/4 tsp garlic powder (optional)
- 1 tbsp fresh chopped parsley (for garnish)
- Butter or non-stick spray for greasing the baking dish
How Much Time Will You Need?
This dish will take you about 15 minutes to prep, plus 35-45 minutes to bake. Letting it sit for 15-20 minutes before baking helps the flavors blend and ensures the croissants soak up the egg mixture just right. In total, you should plan for around 1 hour to 1 hour and 15 minutes to have your casserole ready to enjoy!
Step-by-Step Instructions:
1. Preheat & Prepare:
To get started, preheat your oven to 350°F (175°C). Grease a 9×13 inch casserole dish with butter or non-stick spray to prevent sticking.
2. Layer the Croissants:
Next, tear your croissants into bite-sized pieces and layer half of them evenly in the bottom of your casserole dish. This forms a delicious base!
3. Add the Ham and Cheese:
Spread half of your diced ham over the croissant layer, followed by half of the shredded cheese. This combination of flavors is going to be amazing!
4. Repeat the Layers:
Now, repeat the layering process with the remaining croissants, ham, and cheese. You’ll have a beautiful, layered casserole.
5. Mix the Egg Mixture:
In a bowl, whisk together the eggs, milk, Dijon mustard (if you like a little zing), salt, black pepper, and garlic powder until everything is well combined. This mixture is what will bind everything together.
6. Pour and Press:
Pour your egg mixture evenly over the layered croissant stack. Use a spatula to gently press down to help the croissants soak up the mixture—this makes for a richer flavor!
7. Let it Soak:
Allow the casserole to sit for about 15-20 minutes. This soaking time is important to ensure your casserole comes out perfectly fluffy and flavorful.
8. Bake to Perfection:
Place the casserole in your preheated oven and bake it uncovered for 35-45 minutes. You want the top to be golden brown and for a knife inserted into the center to come out clean. This tells you it’s set and ready!
9. Cool and Serve:
Once it’s out of the oven, let it cool for a few minutes—this makes it easier to serve. It’ll still be warm and inviting!
10. Garnish and Enjoy:
Just before serving, sprinkle some fresh chopped parsley on top for a pop of color and flavor. Now, your warm, cheesy, and savory Ham and Cheese Croissant Casserole is ready to be enjoyed. Dig in!
Can I Use Different Types of Bread?
Absolutely! While croissants give a lovely flaky texture, you can substitute with soft bread like brioche, challah, or even regular sandwich bread. Just make sure to adjust the soaking time as needed based on the bread’s absorption capabilities.
Can I Make This Casserole Vegetarian?
Definitely! Simply omit the ham and consider adding vegetables such as spinach, bell peppers, or mushrooms for a hearty vegetarian version. You can add more cheese or even some plant-based substitutes to maintain a rich flavor.
How Do I Store Leftover Casserole?
Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven or microwave, adding a splash of milk if it’s too dry when you warm it up.
Can I Freeze This Casserole?
Yes! You can prepare the casserole ahead of time and freeze it before baking. Just make sure to cover it tightly with plastic wrap and then foil. When you’re ready to bake, let it thaw in the fridge overnight before cooking as directed.
