Old Fashioned Tomato Pie Simple Recipe: Pressed Oat Crowns With Molasses-Kissed Crunch

This old-fashioned tomato pie simple recipe brings back memories of Sunday suppers with its pressed oat crown crust and sweet-savory filling—no fuss, just pure comfort. The secret lies in the molasses-kissed crunch of the oat topping, which caramelizes beautifully while keeping the filling tender.

I first tried this recipe after a long day of baking, needing something that tasted homemade without requiring hours of work.

The beauty of this pie is its simplicity: a basic pie dough crust, a filling of tomatoes, sugar, and spices, and a topping of oats, molasses, and butter that transforms into golden, crispy crowns.

No special equipment or advanced techniques—just a few key steps to ensure the filling stays juicy and the crust stays sturdy. The molasses adds depth, balancing the tartness of the tomatoes while giving the oat topping its signature caramelized flavor.

By the time it comes out of the oven, you’ll have a pie with a tender, slightly sweet tomato filling and a crown of crispy, molasses-kissed oats that shatters at every bite.

It’s the kind of dessert that feels like a hug—warm, comforting, and impossible to resist. Perfect for family gatherings, potlucks, or just treating yourself to a slice of nostalgia.

Serve it warm with a scoop of vanilla ice cream or whipped cream for the full experience. Let’s get baking—this pie is simpler than it looks, but the results are anything but ordinary.

Ingredients for old fashioned tomato pie simple

Six simple ingredients create the pie crust, while ten more transform into a filling and crown topping.

The molasses is non-negotiable here—it’s what gives the oat topping its signature caramelized depth. Grocery store brands work fine, but if you can find Blackstrap molasses, it’s worth the extra cost for that rich, almost chocolatey note. The old-fashioned rolled oats should be labeled as such; quick oats will work in a pinch, but they lack the chewiness that makes this topping special. For the pie dough, store-bought crust is an option, but making it from scratch ensures the sturdiest base—just keep everything cold to prevent overworking. The no-salt-added tomato sauce is key; if you can’t find it, rinse regular canned sauce well to reduce sodium.

No molasses? Dark corn syrup at half the amount works, though it lacks the same depth. Running short on oats? Crushed graham crackers or cornflakes can stand in, though texture will differ. The brown sugar in the topping is crucial—it caramelizes beautifully with the molasses. If you’re out, white sugar plus a pinch of cinnamon mimics the flavor. For the crust, shortening can replace butter if you’re avoiding dairy, though the flavor will be subtly different. The spices—cinnamon and nutmeg—should be freshly ground if possible; pre-ground spices lose potency quickly, and this pie’s warmth comes from their brightness.

This pie tastes even better the next day, so bake it ahead if you can. Store leftovers in an airtight container in the fridge for up to 4 days, though I’ve never had it last that long. The oat topping stays crisp for about 2 days, after which it softens slightly but remains delicious. For serving, vanilla ice cream is traditional, but whipped cream or caramel sauce works just as well. If freezing, wrap tightly in plastic wrap and foil—it reheats beautifully in a 350°F oven for 15 minutes to restore that fresh-from-the-oven crunch.

Step-by-step instructions for old fashioned tomato pie

This straightforward approach delivers a rustic tomato pie with a crisp oat crown and tender filling.

In a large bowl, combine the 1.5 cups unsalted butter (cold) with the 2.5 cups all-purpose flour and 0.75 cup granulated sugar. Cut the butter into the flour mixture using a pastry cutter or your fingers until the texture resembles coarse crumbs with pea-sized butter pieces remaining.

Add the 1 whole egg and mix just until the dough begins to come together. Then gradually pour in the 0.5 cup ice water, mixing gently with a fork until the dough forms a shaggy mass. Avoid overmixing—the dough should hold together when pressed but still feel slightly crumbly. Divide the dough into two equal parts and flatten each into a disk.

In a separate bowl, whisk together the 2 cups canned tomato sauce, 0.5 cup molasses, 1 tsp ground cinnamon, 0.5 tsp ground nutmeg, and 0.5 tsp salt. Set aside—the filling will develop deeper flavor as it sits while you work with the crust.

Roll out one dough disk on a floured surface to fit a 9-inch pie dish, about 1/8-inch thick. Press it gently into the pan, allowing the edges to extend 1 inch beyond the rim. Chill the crust in the refrigerator while you prepare the oat topping.

In a medium bowl, mix the 1.5 cups old-fashioned rolled oats, 0.5 cup brown sugar, and 1 tsp ground cinnamon. Press this mixture firmly over the chilled crust, creating an even layer that extends slightly beyond the pie dish edges. This creates the signature oat crown that becomes crisp and golden.

Pour the prepared tomato filling over the oat crown, spreading it evenly to within 1/2 inch of the crust edges. Fold the excess crust under itself to create a decorative border, then crimp the edges with a fork or your fingers to seal.

Cut several small slits in the top crust to allow steam to escape. Bake in a preheated 375°F oven for 45-50 minutes, until the crust is deep golden brown and the filling bubbles through the slits. The oat crown should be crisp while the filling remains thick and flavorful.

Remove the pie from the oven and let it cool on a wire rack for at least 20 minutes before slicing. This resting period allows the filling to set slightly and prevents a runny pie. The contrast between the crisp oat crown and tender tomato filling makes every bite satisfying.

Serve warm with 1.5 cups vanilla ice cream on the side if desired. The molasses-kissed filling pairs beautifully with the cool creaminess of vanilla, creating a perfect balance of sweet and tangy flavors. Store any leftovers in the refrigerator for up to 3 days, though this pie rarely lasts that long!

Essential equipment for this recipe

Pie Dish Essentials

You’ll need a 9-inch pie dish with removable bottom or a standard glass pie plate—I prefer Corelle stoneware because it distributes heat evenly and prevents soggy crusts. Avoid dark metal pans, which can make the oat crown brown too quickly.

For a rustic touch, use a cast-iron skillet (like Lodge) lined with parchment paper. 🔥

Rolling Pin & Tools

A wooden rolling pin (like OXO Good Grips) is ideal for rolling the pie dough evenly without tearing. Keep it chilled in the freezer for 5 minutes before use to prevent the dough from sticking.

A pie crust cutter or fork helps create clean edges when crimping the crust. For pressing the oat crown, use the back of a large spoon or your fingers for even distribution.

Mixing & Measuring

Invest in a stainless steel mixing bowl (like Farberware) for the dough—it keeps everything cold and prevents butter from melting prematurely. A pastry cutter (or two forks) works best for cutting butter into flour.

For precise measurements, use a digital kitchen scale (I love OXO’s) for the oats and sugar—volume measurements can vary with packing.

Baking Gear

A wire cooling rack is a must for letting the pie cool evenly without soggy bottoms. For crispier oat crowns, place a baking sheet under the pie dish to catch any drips.

If your oven runs hot, use an oven thermometer (like Thermoworks) to ensure 375°F accuracy—this prevents overbrowning.

Optional Upgrades

For a molasses glaze, whisk 2 tbsp molasses with 1 tbsp water and brush it over the oat crown after baking. A pastry brush (like Silpat’s) makes this easy.

If you’re short on time, a hand mixer (on low speed) helps blend the filling faster, but whisking by hand ensures no lumps. 💡
