Smart Substitutions
Why crustless works: Skipping the traditional pastry crust eliminates most of the flour-based carbohydrates while keeping the creamy egg-and-cheese filling.
Change the cheese: Mozzarella, cheddar, Gruyère, or Monterey Jack can replace the Swiss cheese.
Add more protein: Cooked bacon, diced ham, sausage, or shredded chicken can be added before baking.
Use frozen spinach: Thaw frozen chopped spinach completely and squeeze out as much liquid as possible before adding it to the quiche. This helps prevent a watery filling.
Storage & Reheating
Refrigerator: Store covered or in an airtight container for up to 4 days.
Freezer: Wrap individual cooled slices and freeze for up to 2 months.
Reheating: Microwave an individual slice for 45–60 seconds, or warm in a 325°F oven for about 10 minutes.
