Ingredients

• Croissants: large and fluffy these add richness and soak up the custard for a soft yet crisp top try to use fresh bakery croissants if possible
• Breakfast sausage: classic pork sausage adds a savory bite look for one with good seasoning and not too much fat
• Shredded cheddar cheese: brings a gooey melt and sharp flavor choose extra sharp for bolder taste
• Eggs: large eggs provide structure and richness make sure they are fresh for the fluffiest texture
• Milk: whole milk makes the custard creamy you can use half and half for extra richness if desired
• Dry mustard: gives a tiny bit of warmth and depth do not skip this as it makes a difference
• Salt: enhances all the flavors use kosher salt for best control
• Black pepper: fresh cracked wakes up the whole dish use more or less to taste

Step by Step Instructions

Prepare the Baking Dish:

Grease a large nine by thirteen inch baking dish making sure to get the corners Cover the bottom evenly with croissant pieces so every bite will have that golden base

Add Sausage and Cheese:

Scatter the cooked crumbled sausage over the croissants then sprinkle the shredded cheddar evenly all over This layering ensures you get sausage and cheese in every portion

Make the Egg Mixture:

In a large bowl whisk together eggs milk dry mustard salt and pepper until the mixture is completely smooth and streak free This custard is what binds the casserole and gives it a souffle like quality

Assemble the Casserole:

Gently pour the egg mixture over the croissant sausage and cheese layers Press down with a spatula just enough so the croissant pieces start soaking up the liquid but do not crush them

Refrigerate:

Cover tightly with plastic wrap and refrigerate overnight or at least two hours This long soaking helps the custard absorb and gives the casserole a lush texture

Bake:

Preheat your oven to three hundred fifty degrees Fahrenheit Remove the casserole from the fridge and let it rest on the counter while the oven heats Bake uncovered for about forty five minutes You want the top golden brown and the center set with a bit of a jiggle

Serve:

Let the casserole cool for a few minutes before cutting into squares Serving warm brings out the cheese and sausage flavors the best

One of my favorite parts of this casserole is the way the edges of the croissants crisp up in the oven while the inside stays tender each bite feels luxurious My kids still talk about the first time we ate this on a snowy morning with the windows steamed from baking
