Perfect for gatherings or a cozy night in, it’s a foolproof way to impress with minimal fuss.

Ingredients for Pillsbury Apple Pie Recipe with Crumb Topping

Pantry staples and a store-bought crust make this apple pie effortlessly delicious with its spiced filling.

The apples are key here. Granny Smith holds its shape and tartness perfectly against the sweet topping. Pillsbury crust at most grocery stores saves time without sacrificing flakiness. I grab mine from Wal-Mart or Kroger—always check the expiration date. For the sugars, generic brands work fine, but Domino or C&H are reliable for consistent texture.

Out of Granny Smith? Honeycrisp or Braeburn work in a pinch (just add a splash more lemon to balance sweetness). No old-fashioned oats? Quick oats at the same amount are fine. Want more spice? Add a pinch of nutmeg or allspice. The butter must be cold—don’t soften it first (that’s the trick for clumpy, perfect crumbs).

Baked pie keeps 3 days at room temperature (loosely covered) or 1 week refrigerated. The topping softens over time, so serve warm for that crisp texture. Freeze slices up to 3 months—reheat in a toaster oven to revive the crunch.

Step-by-Step Instructions for Pillsbury Apple Pie With Crumb Topping

Here’s the method I rely on for a pie with tender apples and a buttery oat crumble.

Step 1: Prepare and Pre-Bake the Pie Crust

Unroll one Pillsbury Refrigerated Pie Crust and fit it into a 9-inch pie dish. Press it firmly against the bottom and sides, then crimp the edges with your fingers or a fork. I always dock the crust by pricking the bottom all over with a fork—this prevents it from puffing up during baking.

Preheat your oven to 375°F and blind-bake the crust for 8-10 minutes until it’s just starting to set but not brown. This creates a barrier between the filling and crust, keeping the bottom from getting soggy. Let it cool slightly while you prepare the filling.

Step 2: Toss the Apple Filling

Peel, core, and thinly slice the 6 whole Granny Smith Apples. In a large bowl, toss them immediately with the 1 tbsp Lemon Juice to prevent browning. Add the 0.75 cup Granulated Sugar, 0.5 cup Brown Sugar, 0.5 cup All-Purpose Flour, 1.5 tsp Ground Cinnamon, and 0.25 tsp Salt.

Mix gently but thoroughly so every slice is coated. The flour will thicken the juices as the pie bakes, while the cinnamon and sugars create that classic sweet-spiced flavor. Add the 1 tsp Vanilla Extract last and stir once more to distribute evenly.

Step 3: Assemble and Bake the Pie

Pour the apple mixture into the pre-baked crust, mounding it slightly in the center. Arrange the apples so they’re evenly distributed—this ensures even cooking and prevents air pockets. The filling will seem high, but it will settle as it bakes.

Return the pie to the 375°F oven and bake for 25 minutes. You’ll start to see the filling bubble and the apples soften during this time. If the crust edges begin to brown too quickly, cover them with a pie shield or foil.

Step 4: Add the Crumb Topping and Finish Baking

While the pie bakes, make the topping. In a bowl, combine the 1 cup Old-Fashioned Rolled Oats, 0.5 cup All-Purpose Flour, 0.5 cup Brown Sugar, and the 0.75 cup Unsalted Butter (cold and cubed). Use your fingers to work the butter into the dry ingredients until the mixture resembles coarse crumbs.

After the initial 25 minutes, carefully remove the pie and sprinkle the crumb topping evenly over the apples. Return it to the oven and bake for another 25-30 minutes until the topping is golden brown and the filling is bubbling at the edges. The apples should be tender when pierced with a knife.

Let the pie cool for at least 2 hours before serving. This waiting period allows the filling to set properly, so each slice holds its shape with that perfect balance of juicy apples and crisp topping.

Creative Variations of These Flavors

Caramel Apple Twist

Drizzle the baked pie with ½ cup store-bought caramel sauce and sprinkle with ¼ cup chopped pecans before adding the crumb topping. This adds a gooey, nutty dimension that pairs beautifully with the cinnamon-spiced apples. 💛

Spiced Chai Version

Add 1 tsp chai spice blend (or mix ¼ tsp each cardamom, ginger, and cloves) to the apple filling. The warm, aromatic spices complement the cinnamon and give the pie a cozy, autumnal depth that feels extra special.

Brown Butter Crumb

Brown the 0.75 cup Unsalted Butter before mixing it into the topping. The nutty, toasty flavor elevates the crumbs to gourmet status. Just let the butter cool slightly before combining to keep the texture clumpy and perfect. 🔥

Mixed Berry Apple

Toss 1 cup frozen mixed berries with the apples before baking. The berries release juices that blend with the cinnamon filling, creating a vibrant, fruity twist. No need to thaw—just add them straight from the freezer.

Maple Pecan Topping

Swap the brown sugar in the crumb topping for ½ cup pure maple syrup and add ½ cup chopped pecans. This creates a sticky, nutty topping with a deep, woodsy sweetness that’s irresistible with the tart apples.

Double Crust Option

Use both Pillsbury crusts—one for the bottom and a lattice top instead of crumbs. Brush the lattice with 1 tbsp milk and sprinkle with 1 tbsp granulated sugar for a glossy, crisp finish. It’s a classic look with the same great filling.
