Crustless Bacon Swiss Quiche with Cheese Blend

A rich, protein-packed quiche that eliminates the pastry crust while maintaining all the classic Lorraine flavors. Crispy bacon pieces meld with Swiss, mozzarella, and Parmesan cheeses in a silky egg custard base, enhanced with green onions and a hint of cayenne heat. Perfect for brunch entertaining, meal prep, or using up leftover bacon and cheese. The crustless preparation makes it naturally lower in carbs while keeping the indulgent taste that makes quiche a favorite. Puffs dramatically during baking before settling into a dense, custardy texture that slices beautifully.
