Crack Croissant Breakfast Casserole Recipe – we love this easy overnight breakfast casserole! Only 6 ingredients! Bacon, buttery croissants, cheddar cheese, eggs, half-and-half, and ranch seasoning mix. Assemble the night before and bake in the morning. Great for breakfast, brunch, lunch, dinner, and overnight guests. Serve with some cheesy grits and fresh fruit.
Chop each croissant into 10 to 12 pieces. Place in a lightly greased 9x9-inch deep dish baking dish.
In a skillet over medium-high heat, cook bacon until crispy. Drain fat.
Sprinkle bacon and cheese over chopped croissants.
Whisk together eggs, half-and-half, and ranch dressing mix.
Pour egg mixture over croissant mixture. Press croissants down to submerge into the egg mixture. Cover with aluminum foil and refrigerate for 8 to 24 hours.
Preheat oven to 325ºF.
Bake casserole covered for 35 minutes. Uncover and bake an additional 25 minutes, or until set. Let stand 10 minutes before serving.
Notes:
Make sure to use bakery croissants. This recipe does NOT use refrigerated crescent rolls. Croissants and crescent rolls are NOT the same thing. Make sure to buy croissants from the bakery.
Can substitute turkey bacon for lower calories.
Can substitute heavy cream or whole milk for half-and-half.
You can use any cheese you prefer – gouda, pepper jack, swiss, or Gruyere cheese are good.
If you are sensitive to ranch seasoning, adjust the amount to your personal preference.
Can assemble and refrigerate up to 24-hours before baking.
You can double the recipe and bake in a 9 x 13-inch baking dish for a crowd. You may need to add 10 to 15 minutes to the cooking time to ensure the eggs are set.
Can You Freeze Bacon Croissant Breakfast Casserole? Yes! You can make this casserole in advance and freeze it unbaked or baked.
To bake the casserole after freezing, thaw completely in the refrigerator and bake as directed below.
To reheat after freezing, thaw completely in the refrigerator and reheat in the microwave or covered in the oven. I suggest reheating at 350ºF for about 30 minutes.
Store leftovers in an airtight container in the refrigerator.
