Ingredients for recipe for canning apple pie filling using cornstarch
Six pounds of apples plus these pantry staples—no fancy ingredients, just perfect canned filling.
| Ingredient | Amount | Notes |
|---|---|---|
| Apples (Granny Smith and Honeycrisp blend) 🍎 | 6 lb | Peeled, cored, sliced 1/4-inch thick |
| Cornstarch 🌾 | ½ cup | For perfect thickening consistency |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown preferred |
| Lemon Juice (freshly squeezed) 🍋 | ¼ cup | Brightens flavor, balances sweetness |
| Cinnamon 🌿 | 2 tbsp | Ground, high-quality preferred |
| Salt 🧂 | ½ tsp | Diamond Crystal or kosher |
| Ground Allspice 🌶️ | ½ tsp | For subtle warmth |
| Ground Nutmeg 🌿 | ¼ tsp | Freshly grated preferred |
| Water 💧 | 1 cup | For simmering consistency |
| Pectin (optional, for extra stability) 🍇 | 1 tbsp | Low-sugar variety recommended |
| Ball or Kerr Mason Jars (pint size) 🥫 | 6 jars | New, sterilized, with lids |
| Apple Cider Vinegar (for sterilization) 🍎 | 1 tbsp | For jar and lid sterilizing |
The apples make or break this. Granny Smith and Honeycrisp give you that perfect balance of tart and sweet, but any firm, low-sugar variety works—Fuji or Braeburn are great backups. I always peel mine (the skins can get tough after canning), but if you're impatient, leave them on. Just slice them 1/4-inch thick—thinner slices break down faster and can make the filling too watery. For the best quality, grab apples from local orchards in season—they're fresher than the grocery store and hold their texture better. If you're using store-bought, look for apples that are firm with no soft spots.
No cornstarch? Arrowroot powder at the same amount works, but cornstarch is the secret weapon here—it keeps the filling thick even after months of storage. Fresh lemon juice is non-negotiable; bottled won't cut it. The spices? Penzeys or McCormick for the best flavor, but honestly, whatever you've got in your cabinet is fine. Want to skip the optional pectin? Add an extra 1/4 cup cornstarch for stability, but you might need to adjust sugar slightly. The apple cider vinegar is just for sterilizing—no need to add it to the filling. And if you're short on jars, Kerr or Ball both work, just make sure they're new and never been used for anything other than canning.
This filling keeps for up to a year in a cool, dark pantry—just make sure the jars are sealed properly. I always label mine with the date (yes, even if you think you'll remember). Reheat gently on the stove or microwave until warm—it's perfect for pies, cobblers, or even ice cream toppings. Pro tip: Freeze a few jars if you're not sure you'll use them all within a year. The texture holds up beautifully, and it's a great backup for last-minute baking. Store-bought fillings can't compete with this—it's restaurant-quality every time.

Step-by-step instructions for canning apple pie filling using cornstarch
Here's how to preserve that perfect pie filling texture for months ahead.
Prepare Apples and Sterilize Jars
Peel, core, and slice the 6 lb Apples (Granny Smith and Honeycrisp blend) into ¼-inch thick slices. I use a mandoline for even slices, but a sharp knife works too—just stay consistent. Toss the apple slices with the 0.25 cup Lemon Juice (freshly squeezed) to prevent browning while you work. This acidity also balances the sweetness later.
While the apples prep, sterilize the 6 jars Ball or Kerr Mason Jars (pint size) and lids. Boil them in water for 10 minutes—this kills bacteria and ensures a perfect seal. Keep them hot until you're ready to fill. Real talk: I always double-check the jar rims are clean with a damp cloth before filling, as any residue can prevent sealing.
Cook the Filling to Thick Perfection
In a large, heavy-bottomed pot, combine the sliced apples, 1.5 cups Granulated Sugar, 0.5 cup Cornstarch, 2 tbsp Cinnamon, 0.5 tsp Salt, 0.5 tsp Ground Allspice, and 0.25 tsp Ground Nutmeg. Stir gently to distribute the spices evenly. Add the 1 cup Water and bring to a boil over medium-high heat. Here's the thing—you want the mixture to bubble vigorously for 5 minutes to fully activate the cornstarch.
After boiling, reduce heat to medium-low and simmer for 15-20 minutes, stirring occasionally, until the filling thickens to a spoonable consistency. It should coat the back of a wooden spoon but still slide off easily. If using the 1 tbsp Pectin (optional, for extra stability), add it now and stir for 1 minute to fully incorporate. This optional step creates an even thicker, more stable texture that holds up beautifully after canning.
Fill Jars and Process for Safe Preservation
Ladle the hot filling into the sterilized jars, leaving ½-inch headspace at the top. This space allows for expansion during processing. I use a funnel to avoid spills, and I tap the jars gently on the counter to remove air bubbles. Wipe the jar rims with a clean, damp cloth to ensure a perfect seal.
Place lids on the jars and screw on the bands until fingertip-tight—don't overtighten, or the jars won't seal properly. Add 1 tbsp Apple Cider Vinegar (for sterilization) to each jar before sealing to enhance preservation and add a subtle tang. Process the jars in a boiling water bath for 35 minutes—this time ensures the filling is safely preserved for up to a year.
Cool and Store for Long-Term Use
Remove the jars from the water bath and let them cool undisturbed for 12 hours. You'll hear the satisfying ping as the lids seal—this means your filling is safely preserved. If any jars don't seal, refrigerate and use within a week. The filling should maintain its thick, pie-like consistency even after canning, making it perfect for quick desserts all year round.
Store the sealed jars in a cool, dark place. When ready to use, simply open a jar and warm the filling gently on the stovetop or microwave. It's amazing how fresh it tastes months later—like you just made it yesterday. The cornstarch does its magic by creating that ideal texture that stays perfect, no matter how long it sits on the shelf.
Pro Tips For Making Recipe For Canning Apple Pie Filling Using Cornstarch
- Peel Apples Halfway: Only peel the bottom halves where the skin’s tough and bitter—leave the rest intact. I used to peel everything and lost that lovely texture and flavor. The skin on the top halves adds chew and depth, especially with Honeycrisp.
- Slurry the Cornstarch: Mix cornstarch with cold water first—about 1 tablespoon cornstarch to 2 tablespoons water—before adding it to the pot. This prevents clumping and ensures your filling thickens smoothly, not lumpy. (Yes, even if you’re impatient like me.)
- Simmer, Don’t Boil: Keep the filling at a gentle simmer (tiny bubbles, occasional swirls) for the last 5 minutes. Boiling turns the apples mushy and burns the sugar. I learned this the hard way—my first batch was a gluey mess.
- Acidify with Lemon: Use freshly squeezed lemon juice (about 2 tablespoons) and add it early in cooking. Canned fillings need acidity to prevent botulism, and waiting until the end lets the flavor meld better. (Skip the bottled juice—it’s weaker and tastes off.)
Troubleshooting this dish
Filling Too Thin?
If your filling ends up too thin after canning, you likely didn’t cook it long enough or used too much liquid. For future batches, simmer the filling for an extra 5 minutes to fully activate the cornstarch.
I’ve also found that adding 1 extra tablespoon of cornstarch (for a total of ⅔ cup) helps thicken the filling without altering the flavor. Always stir vigorously during the final 5 minutes of simmering to prevent clumping. 🌾
Jars Not Sealing?
Unsealed jars usually mean either improper sterilization or not enough headspace. Double-check that your jars and lids were boiled for 10 minutes before filling, and ensure you left ½-inch headspace. Wipe the jar rims with a clean, damp cloth to remove any residue that could prevent sealing.
If a jar still doesn’t seal after processing, refrigerate and use it within 1 week—it’s still safe to eat. 🥫
Filling Too Thick?
A filling that’s too thick after canning often means overcooking or insufficient liquid. If this happens, simply add 1-2 tablespoons of water or apple cider to the filling before reheating. For next time, reduce the simmering time by 2-3 minutes or add 1 extra tablespoon of water during cooking.
The goal is a thick but spoonable consistency—think of it like pudding, not glue. 🍎
Mold or Off Flavors?
If your canned filling develops mold or an off smell, it’s a sign of improper sterilization or contamination. Always use fresh, high-quality apples and sterilize jars and lids thoroughly. Store jars in a cool, dark place (like a pantry) and use them within 1 year for best quality.
If you notice any discoloration or unusual odors, discard the jar immediately—better safe than sorry. ⚠️
Filling Separating?
Separation usually happens when the filling isn’t cooked long enough or the cornstarch isn’t fully activated. Stir the filling vigorously during the final 5 minutes of simmering to ensure even thickening.
If separation occurs after canning, simply reheat the filling gently on the stovetop, stirring constantly until smooth. For extra stability, consider adding the optional 1 tablespoon of pectin during cooking. 💫
Apples Too Soft?
If your apples turn mushy after canning, they were likely sliced too thin or overcooked. Stick to ¼-inch thick slices and simmer for no longer than 20 minutes after boiling. Using firmer apple varieties like Granny Smith or Honeycrisp also helps maintain texture.
If you’re in a hurry, peel the apples and slice them right before cooking to preserve their firmness. 🍏

Frequently asked questions
Can I use this filling for anything besides apple pie?
This canned filling is perfect for cobblers, turnovers, or even as a topping for ice cream or cheesecake. The thickened texture holds up beautifully in baked goods, and the warm spices add depth to any dessert. Just reheat gently before using.
How do I know when the filling is thick enough before canning?
The filling should coat the back of a wooden spoon but still slide off easily—like thick pudding. Simmer until it reaches this consistency (usually 15-20 minutes after boiling). If you're unsure, test a spoonful on a plate and let it cool for 1 minute—it should hold its shape.
What if I don't have cornstarch? Can I substitute it?
Yes! Use arrowroot powder in the same amount, or ½ cup all-purpose flour (but you may need to adjust sugar slightly). For canning, cornstarch or arrowroot works best—they thicken evenly and resist thinning during storage. Flour can make the filling gummy.
Do I need a pressure canner for this recipe?
No, a boiling water bath is perfect for this high-acid filling. The lemon juice and vinegar ensure safety, so no pressure canner is required. Just process pint jars for 35 minutes at a rolling boil. Always use the water bath method for acidic foods like fruit fillings.
How can I tell if my canned filling has gone bad?
Check for mold, off smells, or unusual textures. If the lid bulges or doesn't seal properly, discard the jar. When in doubt, throw it out—food safety is critical. Properly sealed jars should last up to a year in a cool, dark place.
