Puff Pastry Breakfast Casserole

Preheat oven to 400ºF.

Heat a large skillet over medium-high heat. Cook bacon, stirring occasionally, until pieces start to brown (4 to 5 minutes). Add sliced onions and cook, stirring occasionally, until bacon is crispy and onions are lightly browned (5 to 7 minutes). With a slotted spoon, transfer mixture to a plate; let cool slightly.

While bacon/onion mixture is cooking, unroll puff pastry to 10-inch square and place in an 8-inch square baking pan. (You might need to fold the corners to fit.) Prick bottom of dough with a fork. Spread bacon/onion mixture over pastry.

In a small bowl, whisk eggs, cream, 1/4 teaspoon salt, and 1/8 teaspoon pepper. Pour egg mixture over the bacon/onion mixture. Sprinkle cheese on top and bake until filling is set and top is golden (about 40 minutes).
