Glass Bakeware Warning

For premade casseroles or leftovers that are in a glass baking dish and have been refrigerated, do not place directly into a hot oven as the glass can shatter. Instead, place any cold glass bakeware into a cold oven to warm up while it preheats. Or, allow the bakeware to rest outside of the fridge for 30 minutes to reach room temperature while the oven preheats.


  • Make-Ahead: This casserole can be prepared and refrigerated, unbaked, overnight. Just take it out of the refrigerator about 30 minutes before baking.

Recipe Variations

  • Use diced leftover or deli ham in place of the bacon or sausage.
  • Omit the bacon or sausage for a vegetarian version of the recipe.
  • Replace the sliced bread with torn croissants, English muffins, or biscuits.
  • Add some sautéed onions and peppers for a brunch dish.
