Tips & Substitutions
For an extra depth of flavor, consider adding a pinch of nutmeg to the egg mixture or mixing in some grated cheese like Gruyere. If you don't have sour cream, plain Greek yogurt works as a great substitute. Make sure to slice the onions thinly for even cooking. You can also use a store-bought pie crust for convenience.
Serving Suggestions
Serve warm or at room temperature, and consider pairing the quiche with a light salad, such as a fresh Swedish Cucumber Salad, for a balanced meal. It can also be enjoyed alongside a cup of soup, like Cold Zucchini And Buttermilk Soup, for a comforting lunch. This dish is perfect for brunch or a light dinner.
Storage & Reheating
To store leftovers, allow the quiche to cool completely, then cover it tightly with plastic wrap or aluminum foil and refrigerate for up to 3 days. To reheat, place slices in a preheated oven at 350°F (175°C) for about 15 minutes, or until warmed through. Microwaving is also an option, but may result in a softer crust.
