In a food processor, pulse together the flour, salt, lard, and butter until it becomes like a meal.
Next, add 1 egg at a time until combined.
While on high speed, slowly drizzle in 2 to 3 tablespoons of water just until the dough comes together.
Transfer the dough onto a clean surface dusted with flour and mold it together to form a disk. Cover in plastic wrap and chill it in the refrigerator for 30 minutes.
In the meantime, whisk together the eggs in a large bowl.
Next, fold in the ricotta, provolone, Pecorino Romano, ham, salami, salt, and pepper until thoroughly combined. Set it aside.
Remove the dough from the refrigerator, place it on a clean surface dusted with flour, cut 1/3 of it off, and set it to the side.
For the larger size, roll it out until it is about 1/8” to ¼” thick and large enough to cover a 9” x 2” spring form pan including going up the sides of the pan.
Transfer the dough to the springform pan sprayed with non-stick spray. You can also an optional parchment paper round to the pan.
Form the dough to the bottom and sides of the pan. There will probably be about 1” to 2” hanging over the sides.
Pour in the egg, cheese, and meat mixture and flatten it out using a rubber spatula.
Return to the clean surface lightly dust the remaining 1/3 piece of dough and roll it out until it is about 1/8” to ¼” thick and large enough to cover the top of the pan.
Trip off excess dough right to the top of the pan. You can freeze or chill the cut-off dough and reuse it in any pie recipe.
Pinch the top and sides of the dough together and then gently roll it over towards the center of the pie. It will only go over about ½” but I just wanted to give directions on where to roll it.
Brush the top of the dough with 1 beaten large egg. You will not use all of it, you just need enough to cover it.
Bake in a preheated oven at 375° on a middle rack for 50 to 60 minutes or until golden brown and cooked throughout. Rest the pizza rustica at room temperature for 20 to 25 minutes.
Notes
Make-Ahead: For freshness, you can make this up to 1 day ahead of time.How to Store: You can store it in the refrigerator for up to 4 days, covered in plastic wrap or an airtight container. Pizza rustica does not freeze well and is not recommended because so much moisture will be lost in the thawing and re-cooking process.How to Reheat: While this is commonly served at room temperature, to reheat it, place your desired portion onto a pan, cover it with foil, and bake it at 350° for 5- 6 minutes or until warm. When using mozzarella, it should be a low-moisture mozzarella instead of fresh so it melts better.If you can find a sheep’s milk or buffalo ricotta cheese, I highly recommend it.Parmigiano Reggiano is a great substitute to Pecorino Romano.If you are using whole milk ricotta in the US, it is wise to drain it in a colander for 15 to 20 minutes first.Feel free to cut in the butter by hand using a pastry knife or in a stand mixer using the paddle attachment.The eggs internally will be around 160° when fully cooked.
