- Brush the border with 2 tablespoons of half and half.
- Bake in a preheated 400°F oven for 15 minutes.

- Bake for an additional 10 minutes or until potatoes are tender and crust is golden.

Tips & Substitutions
For a richer flavor, consider using a mix of butter and olive oil instead of vegetable oil. You can substitute the half and half with whole milk or a plant-based milk for a lighter version. If you prefer a crispy crust, pre-bake the pie crust for 5 minutes before adding the filling. Fresh herbs like thyme or rosemary can enhance the taste of the filling.
Serving Suggestions
Serve the potato onion flat pie warm, cut into wedges, as a comforting main dish. It pairs beautifully with a fresh side salad dressed with Basil Salad Dressing, Maui Style, or a light Dill Dip For Bread for dipping. This dish makes a great vegetarian option for gatherings, and can be accompanied by a glass of white wine to enhance the flavors.
Storage & Reheating
To store leftovers, refrigerate the flat pie in an airtight container for up to 3 days. To reheat, place slices in a preheated oven at 350°F for about 10-15 minutes until warmed through and the crust is crispy again. You can also use the microwave for quick reheating, but the crust may not retain its crispiness.
