How to Make Quiche Lorraine with Caramelized Onions
Prepare Your Oven and Pie Crust: Preheat your oven to 375°F (190°C). Place your pie crust in a 9-inch pie pan, pressing it gently against the sides. Prick it with a fork to prevent bubbling during baking.
Caramelize Those Onions!: In a skillet over medium heat, melt some butter and add thinly sliced onions. Cook them slowly until they turn golden brown and soft—about 20 minutes. Stir occasionally to avoid burning.
Crisp Up the Bacon: In another pan, cook your bacon or lardons over medium heat until crispy. Drain on paper towels to absorb excess grease while you prepare other ingredients.
Create Your Custard Mixture: In a large bowl, whisk together eggs, heavy cream, salt, and pepper until smooth and well combined. This mixture should be creamy but not overly thick.
Add Cheese and Fold in Ingredients: Stir grated Gruyère cheese into your custard mixture gently along with the caramelized onions and crispy bacon bits. Make sure everything is evenly distributed for consistent flavor.
Assemble and Bake Your Quiche!: Pour the filling into your prepared pie crust and bake for 35-40 minutes until set and lightly golden on top. The edges should be crisp while the center remains slightly jiggly.
Let it cool slightly before slicing—this allows flavors to settle and enhances those Instagram-worthy moments when serving!
Enjoying this Quiche Lorraine with Caramelized Onions will elevate any meal from ordinary to extraordinary!

Perfecting the Cooking Process
Start by caramelizing your onions first; it takes patience but rewards you with flavor. While the onions are cooking, prepare your quiche filling and preheat your oven to 375°F (190°C). Once the onions turn golden brown and sweet, mix them into your egg mixture before pouring it into the crust. This sequence ensures perfect consistency and taste.
Add Your Touch
