Cheesy Allium Quiche

Inspired by Ruth Reichl’s grilled cheese sandwich, this quiche is so flavorful, you’ll want a second – or third – slice. Not just for cheese-lovers, the recipe also calls for myriad alliums, from leeks and shallots to red onion and scallions, which are still farm-fresh this time of year.

Cheesy Allium Quiche

Serves | 4 to 6 |

  • 1 store-bought pastry crust
  • 3 Tbsp softened butter, divided
  • 1 small red onion, thinly sliced
  • 4 leeks, white parts only, thoroughly washed and thinly sliced
  • ¾ tsp kosher salt, divided
  • 4 medium shallots, peeled and thinly sliced
  • 6 scallions, white and light green parts only, thinly sliced
  • 4 cloves garlic, minced
  • ½ lb sharp white Cheddar, sliced
  • 12 slices bacon, fried crisp and crumbled
  • 1 cup grated extra-sharp Cheddar, divided
  • 1 cup grated Gruyère, divided
  • 6 eggs
  • 1 tsp Dijon mustard
  • 1½ cups cream
  • ½ tsp freshly ground black pepper, divided

| Preparation | Preheat oven to 350°F. Fill a tart pan or pie plate with 2-inch sides with crust. Dock crust by pricking it with a fork; fold over the top with a high crimp to help hold in filling. Brush 1 tablespoon butter over entire crust. Set in refrigerator while you make the filling.

In a large skillet over medium heat, add remaining butter. When it starts to bubble, add onion, leeks and a pinch of salt; cook, approximately 2 minutes, stirring to break up leeks. Add shallots and another pinch of salt; cook, 2 to 3 minutes, stirring occasionally. Add scallions and garlic; cook, 1 to 2 minutes, stirring occasionally. Remove from heat and allow to cool.

Remove crust from refrigerator. Fill with white Cheddar slices and then bacon and half the grated cheeses. Add sautéed alliums; top with remaining cheese.

In a bowl, whisk eggs, mustard and cream with remaining salt and pepper. Place tart pan on a rimmed baking sheet. Carefully pour egg mixture over contents of crust. Gently slide baking sheet into oven; bake, 1 hour, turning after 30 minutes. The quiche is done when a knife inserted in the center comes out clean. Remove from oven and set tart pan on wire rack to cool, 20 minutes. Serve with greens.
