Savory Ham and Swiss Quiche

Why This Savory Ham and Swiss Quiche Works

In the oven, the eggs and half-and-half slowly set into a soft custard that holds everything in place. As the heat moves in from the edges, the egg mixture starts out runny, then thickens and firms up just enough to slice, but still stays creamy. The ham and Swiss are trapped inside that custard, so they do not dry out. Instead, the cheese melts around the ham and fills the gaps, which keeps the bites moist and a little stretchy.

While everything bakes, the pie crust supports the filling and gives it shape. The crust shields the bottom from the wet egg mixture, so the center can cook through without turning soggy. Nutmeg and pepper spread through the custard as it bakes, so every bite tastes even. After it comes out of the oven, a short rest lets the hot custard settle and finish firming up, which is why the slices cut cleanly instead of running all over the plate.

Mistakes To Avoid

Letting the quiche bake too long can make the eggs puff up, crack, and then collapse into a dry, spongy layer. Instead of a smooth, custardy center, the filling turns rubbery and the cheese can turn hard and greasy on top.

Pouring the egg mixture into a warm or pre-baked crust that has just come out of the oven often causes the fat in the crust to melt too fast. The liquid filling then seeps into the dough, so the bottom bakes up soggy instead of staying crisp.

Using very cold ham straight from the fridge can throw off the baking time. The center of the quiche stays cooler for longer, so the edges set and brown while the middle is still loose and undercooked.

Whisking the eggs and half-and-half only lightly leaves streaks of egg white in the mixture. Those streaks cook into chewy, rubbery bits instead of blending into one smooth, even custard.
