Ingredients
- Bakery croissants: give a buttery tender bite Choose fresh and fluffy croissants for best results
- Bacon: brings crispy smoky flavor Use thick cut for bold crunch or swap in turkey bacon for a lighter option
- 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
- Half and half: creates a creamy soft custard You can swap for whole milk for a lighter result or heavy cream for even more richness
- Ranch dressing mix: infuses a bold herby tang Choose a blend with plenty of fresh spice or mix your own for extra control
Step-by-Step Instructions
- Prep the Croissants:
- Chop each croissant into bite size pieces so every chunk gets a little egginess Place them in a lightly greased deep baking dish and spread to cover the surface
- Cook the Bacon:
- Fry the bacon in a skillet over medium high heat until dark golden and crisp Let it drain on paper towels so you get the crisp bites without grease
- Layer Croissants Bacon and Cheese:
- Sprinkle the bacon and cheddar evenly over the croissant pieces Make sure to tuck some cheese deep so every serving gets a gooey surprise
- Mix the Custard:
- Whisk the eggs together with half and half and ranch mix until even without streaks Beat well so you taste flavor in every bite
- Assemble and Chill:
- Pour your custard over the croissants Press everything down with a spatula so each piece soaks up the creamy mix Cover with foil and chill overnight or for at least eight hours
- Bake the Casserole:
- Heat your oven to three hundred twenty five degrees in the morning Keep the casserole covered and bake for thirty five minutes Uncover and bake for an extra twenty five minutes so the top turns golden Let it sit at room temperature for ten minutes so it slices neatly

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
