Ingredients

• 1 piece store-bought pie crust (or homemade crust)
• 2 tablespoons unsalted butter
• 1 large yellow onion
• 1 medium red bell pepper
• 4 large eggs
• 1 cup heavy cream
• 0.5 cup whole milk
• 1.5 cups Gruyere cheese, grated
• 0.5 teaspoons salt
• 0.25 teaspoons black pepper
• 0.125 teaspoons ground nutmeg (optional)

Directions

Step 1

Preheat your oven to 375°F (190°C). Unroll the pie crust and gently press it into a 9-inch pie or tart pan, trimming any excess dough from the edges. Prick the bottom of the crust with a fork to prevent bubbling, then refrigerate while preparing the filling.

Step 2

Heat a medium skillet over medium heat. Add the butter and let it melt. Thinly slice the onion and red bell pepper, then add them to the skillet. Cook for 8–10 minutes, stirring occasionally, until the onions are soft and caramelized, and the bell peppers are tender. Remove from heat and let cool slightly.

Step 3

In a medium bowl, whisk together the eggs, heavy cream, milk, salt, black pepper, and nutmeg (if using) until smooth and well-combined.

Step 4

Sprinkle half of the Gruyere cheese evenly over the bottom of the chilled pie crust. Spread the cooked onion and red bell pepper mixture over the cheese layer, then top with the remaining Gruyere cheese.

Step 5

Pour the egg mixture over the filling, gently shaking the pan to help distribute it evenly.

Step 6

Place the quiche on a baking sheet to catch any spills, then bake in the preheated oven for 40–45 minutes, or until the custard is set and the top is golden brown. A knife inserted into the center should come out clean.

Step 7

Remove the quiche from the oven and let it cool for 10–15 minutes before slicing. Serve warm or at room temperature for breakfast, brunch, or a light dinner.
