Bacon Rose Quiche

Preheat the oven to 450 degrees F (230 degrees C).

Place 10 slices bacon in a large skillet and cook over medium-high heat, turning occasionally, until crispy and evenly browned, 7 to 10 minutes.

Drain bacon slices on paper towels and crumble.

Heat butter and olive oil in a same skillet over medium heat.

Stir in mushrooms and onion.

Add 1/4 teaspoon salt and pepper.

Cook, stirring occasionally, until mushrooms and onions are slightly brown and tender, about 8 minutes.

Sprinkle mushroom-onion mixture, crumbled bacon, Swiss cheese, Gruyere cheese, and green onions into the pie crust.

Whisk eggs slightly in a bowl; beat in cream, 3/4 teaspoon salt, garlic powder, sugar, nutmeg, and cayenne pepper.

Pour egg mixture carefully into the pie crust.

Thread a toothpick through 1 end of 1 of the remaining bacon slices; roll the bacon around the toothpick to form a rose shape.

Repeat with the remaining bacon slices.

Arrange bacon roses on top of the quiche.

Bake in the preheated oven for 15 minutes.

Reduce oven temperature to 300 degrees F (150 degrees C).

Continue baking until a knife inserted in the middle comes out clean, about 30 minutes more.

Cover with aluminum foil if top is getting too brown.

Let quiche rest for 10 minutes before cutting.
