There’s something magical about recreating a taste of home in a foreign kitchen. When we moved to Portugal, we brought with us a deep love for Philadelphia’s iconic tomato pie—a thick-crusted, saucy, cheese-dusted pizza variant that’s as humble as it is addictive. But making it abroad came with challenges: sourcing the right flour, adjusting to humid Lisbon air, and perfecting a high-hydration dough without making a sticky mess. Then we discovered Kenji López-Alt’s Detroit-style pizza recipe, and a light bulb went off. Why not hybridize the techniques? The result is a Philly-style tomato pie with a crispy, oil-fried crust inspired by Detroit pizza, but with the bold tomato simplicity that defines South Philly bakeries.
Living far from Philadelphia heightens the craving for those familiar, simple flavors. In Portugal, we can’t just walk into Sarcone’s Bakery and grab a slice. So we had to innovate. By combining the high-hydration dough and pan-frying method of Detroit pizza with a classic Philly tomato sauce, we created a version that’s both nostalgic and wonderfully approachable. And the best part? It’s easier than you think.
For those unfamiliar, Philly-style tomato pie is a rectangular, thick-crusted pizza topped with a robust, garlicky tomato sauce and a dusting of pecorino Romano—no mozzarella. It’s served at room temperature, making it perfect for parties, picnics, or spontaneous snacking. In Philadelphia, it’s a staple at Italian bakeries and corner pizzerias, often sold by the square. Our recipe channels that same spirit but with a crisp, crackly bottom that rivals any Detroit-style pan pizza.
Ingredients: Two Simple Components
The beauty of Philly-style tomato pie lies in its minimalism. You need a well-developed dough and a thick, flavor-packed sauce. Let’s break down each.
1. The Dough
Bread flour with at least 10% protein is non-negotiable—it provides the gluten structure needed for a chewy yet crisp crust. Instant yeast simplifies activation; just mix with warm water (90–100°F / 32–38°C). Cold tap water? Warm it gently on the stove and use an instant-read thermometer for precision. Salt enhances flavor and controls fermentation.
Pro Tip: Check your flour’s protein percentage on the package. If it’s below 10%, consider adding vital wheat gluten. The water temperature is crucial—too hot kills yeast, too cold slows activation.
2. The Sauce
Tomato passata (or crushed whole tomatoes) forms the base. Unlike pasta sauce, pizza sauce should be thick enough to spread without pooling. Sauté fresh garlic in olive oil until fragrant, then add the tomatoes and seasonings: dried oregano, garlic powder, onion powder, salt, pepper, and optional chili flake. Simmer until reduced by about a third—about 20–30 minutes. The result is a concentrated, savory sauce that clings to every bite.
3. To Finish
After baking, the pie gets a generous shower of grated pecorino Romano. You can also set out bowls of dried oregano, garlic powder, chili flakes, or even hot honey. The options are endless, but the classic combo is hard to beat.

How to Make Philly-Style Tomato Pie
We’ll walk through the process step by step. The key is patience—especially with the dough. Start the dough at least 2½ hours before you plan to bake.
First, combine flour, instant yeast, and salt in a large bowl. Add warm water and stir with a wooden spoon or dough whisk until a shaggy mass forms. The yeast will begin to bubble—this is good. Let the mixture rest for 20 minutes (or up to 4 hours) to allow the flour to hydrate and the gluten to relax.
Turn the dough onto a clean surface and knead for about 10 minutes. Use your palms to stretch and fold the dough repeatedly. It will start sticky but become smooth and elastic. Perform the windowpane test: stretch a small piece; if it forms a thin web without tearing, you’re done.
Shape the dough into a ball and place it in a lightly oiled bowl. Cover with plastic wrap or a lid and let it rise in a warm spot (70–75°F / 21–24°C) for 2 hours, until doubled.
Meanwhile, preheat your oven to 400°F (200°C) on the conventional setting, with a pizza stone on the middle rack if you have one—otherwise, you can bake directly on the oven floor.
After 2 hours, generously coat a 10×14-inch metal pan with 3 tablespoons of olive oil. Gently transfer the dough to the oiled pan and press it into a rectangle. Stretch it as far as it will go—it probably won’t reach the corners yet. That’s fine. Let it rest for 30 minutes. The gluten will relax, allowing you to stretch the dough to the pan’s edges.
While the dough relaxes, make the sauce. Heat 3 tablespoons olive oil in a saucepan over medium heat. Add minced garlic and cook just until fragrant, about 1 minute. Stir in tomato purée, oregano, garlic powder, onion powder, salt, pepper, and optional chili flake. Reduce heat to low and simmer, stirring occasionally, until thickened, about 20–30 minutes. If the sauce sticks, add a splash of water.
Once the dough has relaxed, stretch it fully to the pan edges. Spoon the sauce evenly over the dough, leaving a ½-inch border. Place the pan on the preheated stone (or oven floor) and bake for 10–15 minutes. You’ll know it’s done when the crust pulls away from the pan and the bottom is golden brown. Use a spatula to lift the pie out—it should slide out easily.
Transfer the pie to a cooling rack to maintain its crunch. While still warm, grate pecorino Romano generously over the top. You can also sprinkle oregano, garlic powder, or chili flake. Let it cool to room temperature—the traditional way to serve—or dig in hot. Either way, the texture is remarkable: a crackling, oil-crisped base with an airy crumb and a bold tomato kick.
Slice into eight squares and serve. This pie keeps well for hours, making it a perfect party dish. Store leftovers in an airtight container at room temperature for up to a day—reheat in a skillet for best results.
