Bacon And Mushroom Quiche With Caramelized Onions

"This bacon and mushroom quiche is loaded with thick-cut bacon, caramelized onions, and asiago cheese for the perfect savory brunch dish. I love a good quiche, and this bacon and mushroom quiche just might be my best creation yet! It's packed with savory flavors and hearty enough for breakfast or brunch. The star of the show here is those caramelized onions. Cooking them down to a jammy consistency takes a bit of time, but it's so worth it! The result is a naturally sweet onion jam that goes perfectly with the earthy mushrooms."
