Tomato & Swiss Cheese Quiche

Tomato and Swiss quiche lives or dies on one technique: reducing the tomato mixture before it ever touches the crust. Fresh tomatoes are mostly water, and water turns a custard quiche into a soggy mess. Cooking the chopped tomatoes, onion, butter, and herbs down by half concentrates the flavor and saves the crust from a watery fate.

Blind-baking the pie crust for 10 minutes before filling is the second non-negotiable step. A raw shell goes pale and gummy under wet filling. A par-baked one stays sandy and golden, the way a quiche crust should be.

The two-temperature bake is also doing real work. The initial blast at high heat sets the custard quickly so it doesn’t seep into the crust, then the lower temperature brings the center up gently without curdling the eggs. Skip the temperature drop and you end up with a rubbery, weeping quiche.

Swiss cheese melts into long stretchy strands and brings a nutty, slightly sweet flavor that plays beautifully against the acidity of cooked tomatoes. Gruyère works equally well if you’ve got it.

Chef Tips

• Peel and seed the tomatoes as the recipe says. The skins curl into ribbons in the oven and the seeds add bitterness.
• Sprinkle the cheese directly on the par-baked crust before adding the tomato mixture. The cheese melts into a moisture barrier that protects the crust.
• Let the quiche rest for at least 10 minutes before slicing. Cut too soon and the custard runs.
• Use a metal pie pan for crispier crusts; ceramic looks pretty but conducts heat slower.

Variations

• Add 4 strips of crumbled crispy bacon over the cheese for a smoky upgrade.
• Stir in a handful of chopped fresh basil or chives into the egg mixture for a brighter herb note.
• Swap Swiss for sharp white cheddar plus a tablespoon of grated Parmesan for a deeper, saltier finish.
