Instructions

Remove from heat and allow the mixture to cool slightly.
In a large bowl, whisk together eggs and milk or cream until smooth.
Add salt, black pepper, garlic powder, and optional nutmeg or red pepper flakes.
Stir in most of the shredded cheese, reserving some for the topping.
Fold in the cooked spinach mixture.
If using turkey bacon or ham, add it now.
Spread the potatoes evenly in the prepared baking dish.
Pour the egg mixture over the potatoes.

Tips
Remove Moisture from Potatoes
Dry potatoes help prevent a watery quiche.
Use Freshly Grated Cheese
Fresh cheese melts better and creates a creamier texture.
Don’t Overcook the Eggs
Remove the quiche once the center is just set.
Cook Spinach First
This removes excess moisture and concentrates flavor.
Use Heavy Cream for Richness
Cream creates a silkier and richer filling.
Let the Quiche Rest Before Slicing
This helps the filling firm up properly.
Season the Potatoes Well
Potatoes absorb flavor, so seasoning is important.
Mix Cheeses for Extra Flavor
Cheddar and mozzarella together work beautifully.
Add Fresh Herbs at the End
Fresh herbs brighten the final dish.
Meal Prep Friendly
This quiche stores and reheats very well.

Mediterranean Version
