Step 1

Preheat oven to 400°F. Let pie crust thaw at room temperature for 10 minutes. Bake until lightly browned, 10 to 15 minutes. Let cool slightly, about 10 minutes. Reduce oven temperature to 375°.

Step 2

Meanwhile, cook broccoli according to package directions until tender-crisp, about 3 minutes. Coarsely chop any larger pieces.

Step 3

Heat oil in a large skillet over medium-high heat. Add onion and cook until light golden, 8 to 10 minutes.

Step 4

Whisk together eggs and evaporated milk in a medium bowl. Stir in the broccoli and onion along with cheese, salt and pepper. Pour the mixture into the cooled crust.

Step 5

Bake until the center is just set and the edges are golden brown, 30 to 35 minutes. Let stand for 10 minutes before serving.
