Common Mistakes to Avoid
Making Pepperoni Pizza Keto Crustless Quiche can be easy, but there are a few common pitfalls to watch out for.
- Skipping the cheese mixture: Failing to combine the cheeses with the herbs can lead to uneven flavor throughout the quiche. Make sure to mix them well before adding them to the pie dish.
- Overcooking the mushrooms: Cooking mushrooms too long can make them rubbery and diminish their flavor. Sauté them just until they are browned and have released their liquid.
- Not draining olives properly: Wet olives can make your quiche soggy. Always drain them thoroughly before adding them to the mixture.
- Ignoring egg mixture consistency: If your egg and cream mixture isn’t well combined, you’ll end up with pockets of uncooked egg in your quiche. Beat it well until everything is fully blended.
- Underestimating cook time: Checking for doneness too early might leave you with undercooked eggs. Ensure the quiche is fully set and lightly browned on top before removing from the oven.
