Key ingredients
Onions, heavy cream, eggs, bacon lardons, butter, Gruyère cheese, salt, pepper, nutmeg.
How to make it keto
Must be prepared without a pastry crust. Confirm no flour or starch is used as a thickener in the onion-cream mixture. Ensure onions are caramelized naturally without added sugar.
Say this to the waiter (German)
Keto Zwiebelkuchen bitte. Ist er ohne Teigboden? Keine Mehl-/Stärkebindung in der Zwiebel-Rahm-Mischung? Werden die Zwiebeln ohne Zucker karamellisiert?
Keto Zwiebelkuchen, please. Is it crustless? No flour/starch to thicken the filling? Are onions caramelized naturally, no added sugar?
Watch out for
Traditional pastry crust (must be omitted), flour or starch thickeners, excessive sugar used to caramelize onions, high-carb side accompaniments.
