Impossible Breakfast Pie (Quiche)

The “impossible” part is how a crustless quiche manages to form its own soft, biscuit-like base as it bakes. Bisquick, eggs, milk, and sour cream get blended together and poured over browned sausage, scallions, and mozzarella. The Bisquick sinks and sets into a tender bottom layer while the egg custard rises.

Sour cream in the batter is the ingredient that makes this version stand out from the standard impossible pie. It adds a rich tanginess and keeps the custard incredibly creamy, almost like a savory cheesecake filling.

Browned and crumbled sausage on the bottom means every forkful has a meaty, savory bite anchoring the fluffy egg layer above. Scallions add a mild onion freshness throughout.

Kitchen Tips

• Brown the sausage thoroughly and drain all the grease. Excess fat makes the bottom of the pie greasy and prevents the Bisquick layer from setting properly.
• Blend the batter for a full minute so the Bisquick is completely smooth. Lumps mean uneven texture.
• The knife test is your friend here. Insert a knife in the center and it should come out clean. If it’s still wet, give it another 5 minutes.
• Let the pie rest for 10 minutes before cutting. The custard firms up and slices stay neat.

Variations

• Swap mozzarella for sharp cheddar or Swiss for a stronger cheese flavor.
• Use crumbled bacon instead of sausage for a different protein.
• Add diced bell peppers or mushrooms to the sausage layer for extra vegetables.
