Preparation

  • Preheat the oven to 425°F, line a baking sheet with parchment paper, and grease a 9x13 inch baking dish with butter.
  • Slice each croissant into four pieces and place on the parchment lined baking sheet. Toast the croissants in the preheated oven for 5 minutes, or until they are dried but not extra golden.

Creating the Casserole

  • Reduce oven heat to 350°F. Arrange the toasted croissant quarters in the prepared baking dish. Scatter the chopped bacon over the croissants.
  • Whisk the eggs, parsley, onion powder, garlic powder, dry chives, salt, pepper, milk, and cream together in a large mixing bowl. Add ¾ cup of the Colby Jack cheese and ¾ cup of smoked Gouda. Mix well.
  • Pour egg mixture over the croissants and bacon. Use a spatula to press down gently on the crescents to soak them with the egg mixture.
  • Sprinkle the remaining cheese over the surface of the casserole.
  • Bake in the preheated oven for 40-45 minutes or until it is nice and golden. Serve immediately.

Notes

For a firmer set, allow casserole to rest 10 minutes before slicing. Refrigerate leftovers up to 3 days; reheat at 350°F for 12-15 minutes. Freeze individual slices wrapped in foil up to 2 months, thaw overnight in the fridge before reheating.
