America's Test Kitchen - How to Make Parmesan Swiss Chard Pie (Erbazzone) | America's Test Kitchen (S24 E4)
The video provides a step-by-step guide to making Erbazzone, a savory pie from the Italian region of Emilia-Romagna. The process begins with preparing a unique pie crust using a combination of butter and flour to create a tender and flaky texture. The filling is made with Swiss chard, pancetta, and Parmesan cheese. The pancetta is cooked to render its fat, which is then used to sauté onions and garlic. Swiss chard is added in batches to wilt and release its moisture, ensuring the filling is not soggy. The cooled filling is combined with Parmesan cheese and the reserved pancetta. The pie is assembled by rolling out the dough, adding the filling, and sealing it with a top crust. The pie is baked until golden brown and crispy, with the pancetta on top adding flavor and texture. The final product is a rustic, flaky pie with a rich, savory filling.

1. 🍝 Exploring Emilia-Romagna's Culinary Delights
- Emilia-Romagna is renowned for iconic foods like Parmigiano, prosciutto, mortadella, and balsamic vinegar, which are integral to Italian cuisine.
- Erbazzone, a savory pie made with spinach and cheese, is highlighted as a traditional snack, particularly enjoyed during summer and fall.
- Parmigiano-Reggiano, known as the 'King of Cheeses,' is aged for a minimum of 12 months, offering a rich flavor profile.
- Prosciutto di Parma is a dry-cured ham that must be aged for at least 12 months, prized for its delicate texture and flavor.

- Adding more examples, such as Tortellini, a pasta filled with meat or cheese, illustrates the diversity and richness of the region's culinary offerings.
2. 🥧 Making the Erbazzone Crust
- Begin by preparing the dry ingredients: combine 1 1/2 cups of all-purpose flour with one teaspoon of table salt and pulse until mixed.
- Incorporate two sticks of unsalted butter and process for about 30 seconds, forming a homogeneous paste which prevents gluten formation and ensures a tender crust.
- Break the paste into two-inch pieces, then add an additional cup of all-purpose flour, pulsing four to five times to achieve pieces smaller than one inch.
- For a flaky texture, grate 1/2 stick of butter, freeze it, and then add it to the mixture, enhancing the dough's structure.
- Integrate 1/4 cup of ice water by folding it into the mixture, ensuring even distribution without overworking the dough.
- Shape the dough into two discs, forming each into a five-inch square, and refrigerate for at least two hours to fully hydrate the flour, which is crucial for texture development.
3. 🥓 Preparing the Flavorful Filling
- Begin with 3 ounces of pancetta, finely chopped, to add a meaty, pork undertone flavor.
- Divide the pancetta, using 1/3 cup for rendering fat on medium-low heat, which takes 5-7 minutes until golden-brown and crisp.
- Utilize the rendered fat (approximately 1 tablespoon) to cook the rest of the filling, enhancing flavor.
- Add one finely chopped onion and cook until softened for about 5 minutes without browning.
- Use 3 pounds of Swiss chard, cut into 1-inch pieces, stirring in a handful at a time as it wilts.
- Cover the pot to help the Swiss chard cook down quickly, maintaining a bright green color.
- Cook the Swiss chard for an additional 5 minutes until all liquid is evaporated to prevent a soggy pie.
- Transfer the cooked filling to a bowl to cool for about 30 minutes before use.
4. 🧀 Assembling and Baking the Erbazzone
- Add four ounces of finely grated Parmesan cheese to the filling for traditional flavor.
- Include rendered pancetta in the filling to enhance richness and prevent crust sogginess.
- Roll dough into a 10-by-14-inch rectangle to fit a greased baking sheet, ensuring even thickness.
- Brush dough edges with egg wash to seal and prevent leaks during baking.
- Score the top crust into 12 portions before baking for easier cutting post-bake.
- Bake at 400 degrees on the lower middle rack for 30 minutes, rotating halfway for even browning.
- Cool the baked Erbazzone for 30 minutes before serving to allow flavors to set.
