Instructions

Grease an 8×8-inch baking dish to prevent sticking.
Tear the croissants into bite-sized pieces and spread them evenly in the dish.
In a mixing bowl, whisk together the eggs, milk, salt, and pepper until smooth.
Pour the egg mixture over the croissants, gently pressing down so the pieces absorb the liquid.
Sprinkle the shredded cheddar cheese evenly over the top.
Cover the dish and refrigerate it overnight, or for at least 6 hours.
When ready to bake, preheat the oven to 350°F (175°C) and let the casserole sit at room temperature for 15–20 minutes.
Bake uncovered for 30–35 minutes, until the top is golden and the center is set.
Let it cool slightly before slicing and serving.

Notes

Day-old croissants work best as they absorb the egg mixture better.

Add cooked bacon, sausage, or vegetables for variety.

Try different cheeses like Swiss or Gruyère for flavor twists.

Store leftovers in an airtight container in the fridge for up to 3 days.

Reheat individual portions in the microwave or the whole dish in a 325°F oven.

Not ideal for freezing due to croissant texture changes.
