Grilled Tomato Pie Slices (Pennsylvania Style) | Arteflame

Introduction

There is a specific magic that happens when dough meets a hot griddle. Imagine the scent of caramelized yeast and sweet, simmering tomatoes filling your backyard. This isn't just pizza; it's a slice of Philadelphia nostalgia. Authentic Pennsylvania Tomato Pie is distinct—featuring a thick, airy focaccia-like crust topped with a rich, sweet sauce and served at room temperature. When cooked on the Arteflame grill, the bottom gets an impossible crunch while staying pillowy soft inside, offering a smoky nuance that a home oven simply cannot replicate.

Why This Recipe is a Keeper

I adore this recipe because it bridges the gap between a bakery classic and outdoor entertaining. Traditional home ovens struggle to replicate that heavy-duty deck oven crisp, but the Arteflame’s carbon steel cooktop essentially fries the dough in olive oil. It is a low-stress meal that actually tastes better as it cools, making it the ultimate make-ahead dish for potlucks or relaxed family dinners where you want to enjoy your guests' company.

My Top Tips for the Perfect Pie

• Watch the liquid: Ensure your sauce is thick and jammy. A watery sauce will turn your fluffy dough into a soggy sponge.
• Don't fear the oil: Be generous with olive oil on the grill surface. You want to shallow-fry the bottom of the crust to get that golden, glass-like texture.
• Let it rest: This is the hardest part, but waiting until the pie reaches room temperature allows the flavors to meld and the crust to set properly.

Swaps & Substitutions

If you cannot find San Marzano tomatoes, any high-quality plum tomato will work, provided you add a pinch more sugar to balance the acidity. For the cheese, while Pecorino Romano is traditional, a sharp Parmesan or even a hard Asiago adds a lovely savory finish if you prefer a different salt profile.

Ingredients

For the Dough

• 4 cups all-purpose flour (or bread flour for extra chew)
• 1 packet (2 1/4 tsp) active dry yeast
• 1 1/2 cups warm water (110°F)
• 2 tbsp granulated sugar
• 2 tsp kosher salt
• 1/4 cup extra virgin olive oil (plus more for the pan)

For the Sauce

• 1 can (28 oz) crushed San Marzano tomatoes
• 3 cloves garlic, minced or pressed
• 1 tbsp olive oil
• 1 tbsp sugar (adjust to taste, Philly style is sweet)
• 1 tsp onion powder
• 1 tsp dried oregano
• Salt and freshly ground black pepper to taste

Toppings

• 1/2 cup grated Pecorino Romano cheese (essential for authenticity)
• Fresh basil leaves for garnish (optional)

Instructions

Step 1: Prepare the Dough

1. In a small bowl, combine the warm water, yeast, and sugar. Let it sit for about 5-10 minutes until the mixture becomes frothy and bubbly.
2. In a large mixing bowl (or stand mixer), combine the flour and salt. Pour in the yeast mixture and the olive oil.
3. Mix until a shaggy dough forms. Knead on a floured surface or in your mixer on medium speed for about 8-10 minutes until the dough is smooth and elastic.
4. Place the dough in a lightly oiled bowl, cover with a damp cloth or plastic wrap, and let it rise in a warm place for 1.5 to 2 hours, or until it has doubled in size.

Step 2: Simmer the Sauce

1. While the dough rises, prepare the sauce. In a saucepan over medium heat, add the olive oil and minced garlic. Sauté for 1 minute until fragrant but not browned.
2. Add the crushed tomatoes, sugar, onion powder, oregano, salt, and pepper.
3. Simmer on low heat for at least 20-30 minutes. The sauce needs to be thick so it doesn't make the dough soggy. Let it cool completely before using.

Step 3: Fire Up the Arteflame

1. Preheat your Arteflame grill. You want a medium-high heat on the flat cooktop griddle.
2. Brush the flat cooktop generously with olive oil to prevent sticking and to fry the bottom of the crust.

Step 4: Shape and Par-Grill

1. Punch down the risen dough. On a baking sheet or peel, stretch the dough into a large rectangle or oval, roughly 1/2 inch thick.
2. Transfer the dough directly onto the oiled flat cooktop of the Arteflame. Grill for 2-3 minutes on the first side until the bottom is golden brown and crispy, and the top begins to bubble.
3. Flip the dough over.

Step 5: Top and Finish

1. Immediately spread the cooled, thickened tomato sauce evenly over the grilled side of the crust, leaving a small border for the crust edge.
2. Allow the pie to cook for another 3-5 minutes on the bottom side. Since the sauce is already cooked, you are just heating it through and crisping the bottom crust.
3. Remove the pie from the grill.

Step 6: Garnish and Serve

1. Transfer the pie to a wire rack or cutting board. Generously dust the top with the grated Pecorino Romano cheese.
2. Let the pie cool. Authentic Pennsylvania tomato pie is best served at room temperature to allow the flavors to set. Slice into squares and serve.

Tips

Creating the perfect Pennsylvania Tomato Pie requires patience and attention to texture. The most critical tip is to ensure your sauce is thick; a watery sauce will soak into the sponge-like dough and ruin that signature bakery texture. Simmer it down until it creates a mound on a spoon rather than dripping off. Additionally, do not skimp on the olive oil when grilling the dough. The oil essentially fries the bottom of the crust on the Arteflame griddle, creating a barrier that keeps the inside fluffy while providing that satisfying crunch. Finally, resist the urge to eat it piping hot. Letting the pie rest for at least 30 minutes allows the sauce to thicken further and the crust to stabilize, ensuring every bite captures the true essence of this regional delicacy. If you prefer a sharper taste, add the cheese immediately after grilling; for a milder taste, wait until it cools.

Variations

While the classic Philly tomato pie is strictly sauce and a dusting of Romano cheese, culinary creativity allows for several delicious variations that still respect the original concept. You can easily adapt this recipe to suit different palates or dietary needs without losing the soul of the dish. Here are a few ways to switch things up on your Arteflame grill:

• Spicy Arrabiata Style: Add a teaspoon of red pepper flakes to the sauce while simmering for a distinct kick that cuts through the sweetness.
• Old School Anchovy: For a savory umami bomb, place high-quality anchovy fillets on top of the sauce before the final cool-down, a nod to very traditional Italian recipes.
• Garlic Lover’s Pie: Roast whole garlic cloves on the flat cooktop, smash them into a paste, and spread a thin layer on the dough before adding the red sauce.
• Gluten-Free Crust: Substitute the all-purpose flour with a high-quality gluten-free 1-to-1 baking flour blend; ensure you use a binder like xanthan gum if the mix doesn't have it.
• Herb Garden: Instead of just dried oregano, mix in fresh chopped rosemary and thyme into the dough during the kneading process for an aromatic crust.

Best pairings

Since Pennsylvania Tomato Pie is rich, carb-heavy, and features a sweet-acidic sauce, the best pairings are beverages and sides that offer a refreshing contrast or cut through the density of the dough. You want to balance the meal so it feels complete without being overly heavy. Think crisp textures and palate-cleansing drinks that enhance the casual, backyard vibe of grilling.

• Crisp Green Salad: A simple arugula salad with a lemon vinaigrette and shaved parmesan provides a peppery, acidic bite that lightens the meal.
• Italian Hoagies: If you are serving a crowd, cut smaller squares of tomato pie to serve alongside classic Italian meats and cheeses for a full Philadelphia spread.
• Dry Rosé or Chianti: A dry Rosé complements the sweetness of the tomatoes, while a light Chianti pairs beautifully with the herbs and Romano cheese.
• Pilsner or Lager: An ice-cold, crisp beer is the traditional beverage of choice for this bakery staple, scrubbing the palate between savory bites.
