Ingredients

For the Olive Oil Pastry:

1½ cups (190g) all-purpose flour
5½ tablespoons (80ml) extra virgin olive oil
3½ tablespoons (50ml) cold water
½ teaspoon salt

For the Filling:

4 cups (600g) frozen Romanesco cauliflower
0.55 lb (250g) potatoes (preferably Yukon Gold or similar waxy varieties)
3.5 oz (100g) Fontina cheese
1 shallot
2 tablespoons extra virgin olive oil
Salt to taste
Freshly ground black pepper to taste

Step-by-Step Instructions

Preparing the Olive Oil Pastry:

In a large mixing bowl, combine the flour and a pinch of salt, mixing well.
Create a well in the center of the flour and pour in the extra virgin olive oil.
Using your fingertips or a fork, gradually work the oil into the flour until the mixture resembles coarse breadcrumbs.
Slowly add the cold water, about a tablespoon at a time, mixing after each addition until the dough just comes together. You may not need all the water—stop adding when the dough forms a cohesive ball that’s not sticky.
On a lightly floured surface, knead the dough gently for 2-3 minutes until smooth and uniform. Do not overwork the dough or it will become tough.
Form the dough into a disk, wrap it tightly in plastic wrap, and refrigerate for at least 30 minutes (or up to 24 hours) to allow the gluten to relax.

Preparing the Filling:

Peel the potatoes and slice them into thin rounds, approximately ⅛ inch (3mm) thick. Place in a bowl of cold water to prevent browning if not using immediately.
Peel and thinly slice the shallot into delicate rings or half-moons.
If using frozen Romanesco cauliflower, allow it to thaw slightly while preparing the other ingredients. If it’s in large pieces, cut into bite-sized florets.
Using the large holes of a box grater, grate the Fontina cheese and set aside.

Cooking the Filling:

Heat 2 tablespoons of extra virgin olive oil in a large skillet over medium-low heat.
Add the sliced shallot and cook gently for about 5 minutes until softened and translucent but not browned, stirring occasionally.
Drain the potato slices and pat them dry with paper towels. Add them to the skillet with the shallots.
Cook the potatoes for approximately 5 minutes, stirring occasionally to ensure even cooking. They should start to soften but not brown significantly.
Add the Romanesco cauliflower florets to the skillet, stirring carefully to combine with the potatoes and shallots.
Season the mixture with salt and freshly ground black pepper to taste.
Increase the heat to medium-high and cook for an additional 5 minutes, stirring occasionally. The vegetables should be partially cooked but still retain some firmness.
Remove the skillet from the heat and allow the filling to cool to room temperature before assembling the pie.

Assembling and Baking the Pie:

Preheat your oven to 375°F (190°C). If you have a baking stone or steel, place it in the oven now to heat up.
Remove the pastry dough from the refrigerator and let it sit at room temperature for 5-10 minutes to make it easier to roll.
On a lightly floured surface, roll out the dough to approximately ⅛ inch (3mm) thickness, creating a rectangle slightly larger than your baking dish.
Lightly grease a rectangular tart pan (13.5 x 4 inches or approximately 34 x 10 cm) with olive oil.
Carefully transfer the rolled dough to the tart pan, gently pressing it into the corners and up the sides. Trim any excess dough from the edges, leaving a small overhang to account for shrinkage.
Prick the bottom of the pastry several times with a fork to prevent bubbling during baking.
Sprinkle approximately ⅔ of the grated Fontina cheese evenly across the bottom of the pastry shell.
Arrange the cooled vegetable filling over the cheese layer, distributing it evenly throughout the tart.
Top the filling with the remaining ⅓ of grated Fontina cheese, ensuring even coverage.
Place the tart pan on a baking sheet (for easier handling) and transfer to the preheated oven.
Bake for approximately 30 minutes until the pastry is golden and the filling is bubbling.
Increase the oven temperature to 445°F (230°C) and switch to broil/grill mode.
Return the pie to the oven and broil for an additional 3-5 minutes, watching carefully until the top is golden brown and slightly caramelized.
Remove from the oven and allow to cool for at least 10-15 minutes before serving.

Cooking Tips and Tricks

Perfect Pastry: The key to a tender olive oil pastry is minimal handling. Mix just until the ingredients come together and avoid overworking the dough.
Pastry Texture: If the dough feels too dry when mixing, add a few more drops of cold water. If it’s too sticky, dust with a small amount of flour.
Preventing Soggy Bottom: Sprinkling cheese on the base of the pastry creates a barrier that helps prevent the filling’s moisture from making the crust soggy.
Potato Selection: Waxy potato varieties like Yukon Gold or red potatoes hold their shape better in this recipe than starchy varieties like Russets.
Fontina Substitute: If Fontina is unavailable, Gruyère, provolone, or a mild Gouda can work well as alternatives, each bringing its own unique flavor profile.
Filling Consistency: The vegetable filling should be relatively dry before adding to the pastry. If there’s excess moisture after cooking, drain it off to prevent a soggy crust.
Even Cooking: For even browning, rotate the pie halfway through the baking time, especially if your oven has hot spots.
Checking Doneness: The pastry should be golden brown on the edges and bottom. You can lift one edge slightly with a spatula to check that the bottom is cooked.

Variations and Substitutions

Vegetable Options:

Fresh Romanesco: If using fresh Romanesco cauliflower instead of frozen, blanch it in boiling salted water for 2 minutes, then shock in ice water before adding to the skillet.
Regular Cauliflower: Standard white cauliflower makes an excellent substitute if Romanesco is unavailable.
Broccoli Alternative: Broccoli can be substituted for a similar texture but a stronger flavor profile.
Additional Vegetables: Add sautéed mushrooms, leeks, or sweet red peppers for additional layers of flavor.

Cheese Variations:

Cheese Blend: Create a more complex flavor by using a combination of cheeses—try mixing Fontina with Parmesan or pecorino for a sharper note.
Blue Cheese Accent: Add a small amount (1-2 oz) of crumbled blue cheese to the filling for a tangy, sophisticated twist.
Vegan Option: Use a plant-based cheese alternative and ensure your pastry is made with olive oil for a completely vegan version.

Pastry Alternatives:

Herb-Infused Dough: Add 1 tablespoon of chopped fresh herbs (rosemary, thyme, or sage) to the pastry dough for additional flavor.
Whole Wheat Option: Substitute up to half of the all-purpose flour with whole wheat flour for a nuttier flavor and added nutrition.
Time-Saving Alternative: Use high-quality store-bought pastry dough in a pinch, though the olive oil pastry does add a distinctive Mediterranean character.

Flavor Enhancements:

Herb Addition: Mix fresh herbs such as thyme, rosemary, or sage into the filling.
Garlic Lover’s Version: Add 2 minced garlic cloves when sautéing the shallots.
Spice It Up: Add a pinch of nutmeg or smoked paprika to the filling for a warming depth of flavor.
Egg Liaison: For a richer, more custard-like filling, mix 1 egg with 2 tablespoons of cream and pour over the vegetables before adding the final layer of cheese.

Common FAQs

Q: Can I prepare this pie in advance?

A: Yes, this pie is excellent for make-ahead preparation. You can prepare the pastry dough up to 2 days in advance and keep it refrigerated. The vegetable filling can also be prepared a day ahead and stored in the refrigerator. Assemble and bake the pie the day you plan to serve it. Alternatively, you can bake the entire pie ahead of time and reheat it in a 350°F (175°C) oven for 15-20 minutes before serving.

Q: I can’t find Romanesco cauliflower. What’s the best substitute?

A: Regular white cauliflower is the closest substitute in terms of texture and mild flavor. Broccoli is another good option, though it has a stronger flavor profile. You could also use a combination of both regular cauliflower and broccoli to approximate the slightly nutty flavor of Romanesco.

Q: Why did my olive oil pastry turn out tough?

A: Tough pastry usually results from overworking the dough, which develops too much gluten. Handle the dough as minimally as possible, mixing just until combined and kneading very gently. Also, make sure you’re using the correct amount of liquid—too little water can make the dough dry and tough.

Q: Can I freeze this savory pie?

A: Yes, you can freeze the pie either before or after baking. To freeze before baking, assemble the pie completely, wrap it tightly in plastic wrap followed by aluminum foil, and freeze for up to 1 month. Bake directly from frozen, adding about 15-20 minutes to the baking time. To freeze after baking, cool the pie completely, wrap securely, and freeze for up to 2 months. Thaw in the refrigerator overnight and reheat in a 350°F (175°C) oven until warmed through.

Q: The recipe calls for a specific rectangular mold size. Can I use a different shaped pan?

A: Absolutely! This recipe adapts well to different pan shapes and sizes. A 9-inch (23 cm) round tart pan works beautifully, as does an 8×8 inch (20×20 cm) square pan. Just ensure your pastry is rolled out to the appropriate size and thickness. Cooking times may vary slightly based on the pan used—deeper dishes may require slightly longer baking times.

Storage and Make-Ahead Tips

Pastry Dough: The olive oil pastry can be made up to 3 days ahead and stored well-wrapped in the refrigerator. Allow it to sit at room temperature for 15-20 minutes before rolling to prevent cracking.
Filling Preparation: The vegetable filling can be prepared up to 24 hours in advance and stored in an airtight container in the refrigerator. Bring to room temperature before assembling the pie.
Assembled Unbaked Pie: The fully assembled unbaked pie can be refrigerated for up to 24 hours before baking. Cover loosely with plastic wrap to prevent the pastry from drying out.
Baked Pie Storage: Once baked and cooled, the pie can be stored in the refrigerator for up to 3 days. Cover with aluminum foil or plastic wrap to prevent it from drying out.
Reheating Instructions: For the best texture, reheat slices in a 350°F (175°C) oven for 10-15 minutes rather than using a microwave, which can make the pastry soggy.
Room Temperature Serving: This pie is excellent served at room temperature, making it perfect for picnics or buffets. Allow refrigerated pie to sit at room temperature for at least 30 minutes before serving.
Freezing Guide: To freeze, wrap individual portions tightly in plastic wrap followed by aluminum foil. Label with the date and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
Refreshing Day-Old Pie: To refresh the texture of day-old pie, sprinkle a few drops of water on top before reheating in the oven. This creates steam that helps revitalize the pastry.
