Can I make impossible ham and cheese pie ahead of time?

Yes, you can assemble the entire pie up to twenty four hours in advance. Cover the unbaked pie tightly with plastic wrap and keep it in the refrigerator. When you are ready to bake, add three to five minutes to the total baking time to account for the cold start.

Why is it called an impossible pie?

It is called impossible pie because the batter magically forms its own crust while baking. The heavy ingredients sink to the bottom and the flour rises to the top, creating a layered pie without requiring you to roll out a traditional pastry dough.

Can I use a different cheese instead of Swiss?

Yes, you can substitute Swiss with Gruyere for a deeper earthy flavor, or sharp cheddar for a bolder bite. Just avoid pre shredded cheese, as the anti caking additives can prevent the cheese from melting smoothly into the custard.

Do I need Bisquick to make impossible pie?

No, you do not need Bisquick. You can make a homemade biscuit mix by combining one cup of flour, one and a half teaspoons of baking powder, and a pinch of salt. This gives you the same rising power without needing a boxed mix.

How do I know when the pie is fully cooked?

The pie is done when the top is a deep golden brown and the center barely jiggles when you gently shake the pan. A toothpick inserted into the center should come out clean, but the residual heat will finish setting the custard as it rests.

Instructions

1. Preheat the oven and prep the pan: Preheat your oven to 400 degrees F. Generously coat a 9-inch glass pie plate with softened butter, then dust with grated Parmesan cheese to create a savory crust shell.

2. Layer the fillings: Scatter the diced ham, grated Swiss cheese, chopped scallions, and diced onion evenly across the bottom of the prepared pie plate.

3. Mix the batter: In a medium bowl, whisk the eggs, milk, Dijon mustard, pepper, and salt until completely smooth and frothy.

4. Add the dry mix: Sprinkle the biscuit mix over the wet ingredients and whisk gently until just combined, being careful not to overmix.

5. Pour the batter: Pour the thin batter evenly over the ham and cheese fillings in the pie plate.

6. Bake the pie: Place the pie plate on a baking sheet and bake for 40 minutes until the top is deep golden brown and the center barely jiggles.

7. Rest and serve: Let the pie rest on the counter for 5 minutes so the custard sets before slicing into wedges.

Notes

Store in the refrigerator for up to 4 days or freezer for up to 2 months. Reheat at 350 degrees F for 10 minutes.

Pat deli ham dry before using to prevent a soggy bottom crust.

Grate your own cheese from a block rather than using pre shredded to ensure a smooth melt.

Let the pie rest for 5 minutes before slicing so the proteins relax and the custard locks in moisture.
