As seen in: Morning Meals to Start Your Day Right

Layers of buttery croissants, crispy bacon, and sharp cheddar are soaked in a creamy, herby egg mixture to create a satisfying brunch centerpiece. An overnight rest in the refrigerator means the croissants absorb all the rich custard, ensuring each bite is both tender and flavorful. This bake is finished golden and bubbly in the oven, perfect for serving warm to guests or family on lazy mornings or special holidays. Flexible ingredients allow for swaps, like turkey bacon or different cheeses, and it reheats beautifully for leftovers. Simply assemble in advance and bake when you're ready for a comforting and impressive breakfast.

  • Shredded cheddar cheese: melts for gooey richness Sharp cheddar offers a punch but you can use gouda or swiss
  • Large eggs: set the custard and bind the casserole Fresh eggs with golden yolks will give the best base

  • Ranch dressing mix: infuses a bold herby tang Choose a blend with plenty of fresh spice or mix your own for extra control

Layer Croissants Bacon and Cheese:

My favorite part of this casserole is the way leftover bakery croissants come back to life It is a true breakfast rescue remedy and my kids always race for the extra cheesy corners

Storage tips

Once cool store leftovers tightly wrapped in the refrigerator for up to three days For best texture reheat covered in the oven until warmed through For freezing wrap tightly and freeze up to two months Thaw overnight in the refrigerator and reheat at three hundred fifty degrees for about thirty minutes

Ingredient substitutions

For lighter flavor use turkey bacon or even diced ham Instead of cheddar try gruyere pepper jack or swiss for a twist Whole milk can replace half and half If you want a pop of color toss in chopped green onions or spinach

Serving suggestions

Serve a hot square with fresh fruit on the side for a bright contrast For a Southern spin try with creamy grits or a crisp side salad If feeding a crowd cut the casserole into small squares and serve buffet style
