Peach Pie Filling Recipe Frozen Peaches: Sweet Summer Preservation in a Jar

Preserving summer’s sweetness is as simple as making this versatile pie filling from frozen peaches. No fresh fruit required, yet it delivers that sun-ripened flavor in every spoonful.

This method transforms frozen peaches into a thick, glossy filling that works for pies, pastries, or even ice cream toppings. A precise balance of sugar and lemon juice enhances the natural fruit flavor without overpowering it.

The process is straightforward: thaw, cook, and thicken. The result is a shelf-stable filling that captures peak peach season whenever you need it.

Use it immediately or store in jars for up to a year. The possibilities are as endless as summer days.

Ingredients for Peach Pie Filling Recipe Frozen Peaches

Nine ingredients transform frozen peaches into summer in a jar. Simple, shelf-stable, delicious.

Frozen peaches work beautifully here—look for unsweetened slices at Trader Joe’s or your regular grocery freezer aisle. The quality matters less than you’d think since cooking concentrates the flavor. Thaw them completely and drain well (that excess liquid can make your filling soupy). I prefer the bagged slices over whole peaches for ease, but either works if you chop them evenly.

No cornstarch? Instant tapioca at the same amount works just as well. Brown sugar can be swapped for all white sugar if that’s what you have. The spices are flexible—cardamom instead of cinnamon adds an interesting twist. If your peaches are extra tart, bump the sugar up a bit. The lemon juice isn’t optional though—it brightens the whole mixture and balances the sweetness.

This keeps beautifully. Shelf-stable in sealed jars for up to 1 year, or refrigerate for 2 weeks once opened. The filling thickens more as it cools, so don’t worry if it seems thin right after cooking. Perfect for pies, of course, but also spooned over ice cream or swirled into yogurt.

Step-by-Step Instructions for Peach Pie Filling

This method ensures a perfectly thickened, flavorful filling that holds its shape when sliced.

Step 1: Thaw and Prepare the Peaches

Begin by thawing the 6 cups Frozen Peach Slices completely. I spread them on a clean kitchen towel or paper towels to drain well. This prevents excess liquid from making your filling runny. Press gently on the slices to extract as much moisture as possible.

The peaches should be at room temperature before cooking. This ensures even cooking and proper thickening. You’ll notice the peaches will release about ½ cup of liquid during thawing—discard this or reserve it for another use.

Step 2: Combine Dry Ingredients and Spices

In a medium bowl, whisk together the 1.5 cups Granulated Sugar, 0.5 cup Light Brown Sugar, 0.25 cup Cornstarch, 1 tsp Ground Cinnamon, 0.25 tsp Ground Nutmeg, and 0.25 tsp Salt. The cornstarch is critical for thickening, while the spice blend adds warm depth to the filling.

Make sure the brown sugar is packed firmly into the measuring cup for accurate sweetness and richness. The mixture should look evenly distributed with no lumps. This step ensures the spices and thickener are evenly dispersed before meeting the liquid ingredients.

Step 3: Cook the Peach Mixture

In a large, heavy-bottomed pot, combine the drained peaches, the dry ingredient mixture, 0.25 cup Lemon Juice, and 1 tsp Vanilla Extract. Stir well to coat the peaches evenly. The lemon juice brightens the flavor and balances the sweetness perfectly.

Cook over medium heat, stirring frequently with a wooden spoon, for 8-10 minutes. You’ll see the mixture begin to bubble and thicken as the cornstarch activates. Keep stirring to prevent sticking and ensure even cooking throughout the pot.

Step 4: Thicken and Finish the Filling

Once the mixture reaches a full boil, reduce the heat to medium-low and continue cooking for 5-7 minutes. Stir constantly during this time. The filling should thicken to the consistency of a rich pie filling—it will coat the back of a spoon and leave a clear path when you draw a finger through it.

Watch for the color to deepen slightly and the liquid to become glossy. If the filling seems too thick, add a splash of water and stir well. If it’s too thin, cook for an additional 2-3 minutes and recheck. The final product should mound slightly when spooned.

Step 5: Cool and Store the Filling

Remove the pot from heat and let the filling cool at room temperature for 30 minutes. This allows it to set further as it cools. Stir occasionally during this time to release heat evenly and prevent a skin from forming on the surface.

Once cooled, transfer the filling to airtight jars or containers. It will keep in the refrigerator for up to 1 week or can be frozen for up to 6 months. Use this filling for pies, turnovers, or as a topping for ice cream or yogurt.

Pro Cooking Tips for Great peach pie filling recipe frozen peaches

Thawing Perfection

Always thaw your 6 cups Frozen Peach Slices completely on paper towels. Press gently to extract maximum moisture—I use my grandmother’s wooden spoon for this. Discard the ½ cup liquid that accumulates to prevent a watery filling. 💛

Even Cooking

Use a heavy-bottomed pot (I love my Le Creuset Dutch oven) to prevent scorching. Cook over medium heat, stirring constantly with a wooden spoon. The cornstarch needs to reach a full boil to activate properly.

Thickness Test

The filling should coat the back of a spoon and leave a clear trail when you draw a finger through it. If too thin, cook 2-3 more minutes. If too thick, stir in 1-2 tbsp water and recheck.

Spice Balance

Taste before final cooling—this is where I use Nonna’s spoon. Add an extra ¼ tsp cinnamon if you love warm spices, or a pinch more salt to brighten flavors. The vanilla should be subtle but present.

Cooling Trick

Spread the hot filling in a shallow dish before transferring to jars. This speeds cooling and prevents a skin from forming. Stir every 5-10 minutes during the 30-minute cooling period.

Storage Wisdom

For longest shelf life, use sterilized jars and process in a water bath for 15 minutes. Otherwise, refrigerate for up to 1 week or freeze for 6 months. Always label with the date!
