Ingredients for low fat apple pie filling
Eight simple ingredients transform into a light, spiced apple filling—no butter, no guilt.
| Ingredient | Amount | Notes |
|---|---|---|
| Granny Smith Apples 🍏 | 4 medium | Peeled, cored, chopped small |
| Unsweetened Applesauce 🍎 | ½ cup | Unsweetened for healthiness |
| Cornstarch 🌾 | 2 tbsp | For perfect thickening |
| Granulated Sugar 🍚 | ¼ cup | Adjust to taste preference |
| Ground Cinnamon 🌿 | 1 ½ tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated for warmth |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed |
| Vanilla Extract 🌸 | ½ tsp | Pure vanilla preferred |
| Salt 🧂 | ¼ tsp | Sea salt preferred |
| Water 💧 | ¼ cup | Or apple cider for flavor |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For light richness |
Granny Smith apples are the secret weapon here—tartness balances the sweetness perfectly. Buy organic if possible, or give them a good rinse. The applesauce is non-negotiable for moisture without added sugar—Mott's unsweetened is my go-to, but any plain version works. For cinnamon, Penzeys or bulk bins at Whole Foods have the freshest ground. Nutmeg needs to be freshly grated if you've got whole nutmeg—that's where the magic happens—but pre-ground is fine in a pinch. The key is balancing sweetness, so adjust sugar to your taste after tasting the raw apples first.
No Granny Smiths? Fuji or Honeycrisp work great—they're sweeter but still hold up well. Short on applesauce? Substitute mashed banana at half the amount, but it'll add natural sweetness. Cinnamon substitutes? Cassia at the same amount works identically. Nutmeg too strong? Cut it to 1/4 tsp and add a pinch more cinnamon. Lemon juice can be swapped for white vinegar at the same amount, but fresh lemon brightens everything. Olive oil gives just enough richness—skip it if you're watching fat strictly, but I promise you won't miss it. The cornstarch is crucial for that perfect pie filling texture—don't substitute arrowroot unless you want a thinner result.
This filling keeps beautifully—5 days in the fridge in an airtight container, or 3 months in the freezer. I always make a double batch for hand pies—just portion into small containers before freezing. Thaw overnight in the fridge before using. The texture thickens as it cools, so if it seems too thick when warm, add 1 tbsp water and stir. Pairs perfectly with a low-fat crust or even graham crackers for a lighter dessert option. Trust me, you'll want to make this again and again—it's that good.

Step-by-step instructions for low fat apple pie filling
This filling delivers all the cozy spice and texture of classic apple pie with a fraction of the fat.
🍳 Step 1: Sauté the Apples Until Soft
Heat the 1 tablespoon extra-virgin olive oil in a large saucepan over medium heat. Add the 4 medium Granny Smith apples (already peeled, cored, and chopped small) and cook for 5-6 minutes, stirring occasionally. You'll see the apples start to soften and release their juices—this is when their natural sweetness begins to develop.
Here's the thing—don't rush this step. The apples need time to break down slightly before we add the thickeners. You're looking for them to become tender but still hold their shape, almost like al dente pasta. If you see the apples browning too quickly, reduce the heat to medium-low and keep stirring gently. This gentle cooking preserves their texture while building flavor.
👨🍳 Step 2: Build the Spiced Base
In a small bowl, whisk together the 2 tablespoons cornstarch, 0.25 cup granulated sugar, 1.5 teaspoons ground cinnamon, 0.5 teaspoon ground nutmeg, and 0.25 teaspoon salt. This is your flavor powerhouse—cinnamon and nutmeg create that classic pie warmth while the cornstarch will give your filling that perfect thick, spoonable consistency.
Once the apples have softened, sprinkle this dry mixture evenly over them in the pan. Stir immediately to distribute everything evenly. Then add the 0.5 cup unsweetened applesauce and 2 tablespoons lemon juice. The applesauce adds natural sweetness and moisture without extra fat, while the lemon juice brightens all those warm spices. Stir everything together and let it cook for 2-3 minutes until the mixture starts to bubble gently.
🥘 Step 3: Simmer Until Thick and Glossy
Pour in the 0.25 cup water (or apple cider if you prefer) and add the 0.5 teaspoon vanilla extract. Increase heat to medium-high and bring the mixture to a gentle boil. Here's where the magic happens: let it boil vigorously for 3-4 minutes, stirring constantly with a wooden spoon. You'll see the filling thicken dramatically as the cornstarch activates.
Real talk: this is the moment that matters. You want the filling to coat the back of your spoon when you lift it—thick enough to hold its shape when spooned but still smooth and glossy. If it thickens too quickly (it will), immediately reduce heat to medium-low and keep stirring. The filling should simmer for another 2-3 minutes until it reaches that perfect pie-filling consistency where it's thick but still pourable.
⏰ Step 4: Cool and Adjust Seasoning
Remove the pan from heat and let the filling cool for 10 minutes. This resting period allows the flavors to meld and the filling to thicken further. I know it's tempting to taste it immediately, but patience here makes all the difference. The filling will thicken even more as it cools—this is normal and exactly what we want.
After cooling, give it one final taste and adjust sweetness if needed. You can add up to 1 tablespoon more granulated sugar if you prefer it sweeter, or a splash of lemon juice if it needs more brightness. The filling should be perfectly balanced—sweet from the apples and sugar, warm from the spices, with that bright citrus note cutting through. This is your low-fat version of classic apple pie filling, and it's absolutely delicious.
Pro Tips For Making Low Fat Apple Pie Filling
- Prep Apples Like a Pro: Core the apples, but don’t stop there—slice them into even ¼-inch pieces (no thicker) and toss immediately with a splash of lemon juice. Granny Smiths turn mushy fast, and uniform slices cook at the same rate, so you avoid a gooey mess in some spots and undercooked chunks in others.
- Slurry the Cornstarch: Skip the dry dump—mix cornstarch with cold applesauce first (about 1 tablespoon per ½ cup sauce) until it’s a smooth paste. Stirring it in before heat hits prevents clumping, and the sauce thickens like silk instead of turning pasty. (Yes, even if you’re impatient like me.)
- Simmer, Don’t Boil: Bring the filling to a gentle simmer (tiny bubbles, not a rolling boil) and let it cook for exactly 5 minutes after thickening. Boiling burns the applesauce’s natural sweetness and makes the filling taste flat. Lower heat if it’s too vigorous—this isn’t a race.
- Sweeten in Stages: Start with half the sugar, taste, then add the rest. Granny Smiths are tart, but unsweetened applesauce can be deceptive—too much sugar later makes the filling cloying. Adjust cinnamon the same way: a pinch at a time until it sings, not overpowers.
Health benefits of this recipe
Fiber-Rich Goodness
This filling packs a surprising 8 grams of fiber per serving—thanks to the whole apples and applesauce. Fiber supports digestive health by promoting regularity and feeding beneficial gut bacteria.
I've found that the natural pectin in apples actually helps thicken the filling while keeping it lighter than traditional versions with butter or flour. 🌿
Natural Sweetness Control
By using Granny Smith apples and just ¼ cup sugar, you're cutting refined sugar by nearly 75% compared to classic recipes. The tartness of Granny Smiths balances the sweetness perfectly, so you won't miss the extra sugar.
I've tested this with diabetic friends, and they consistently say it satisfies their sweet tooth without spiking blood sugar.
Low-Fat Protein Boost
While not a protein powerhouse like meat or beans, this filling contains 1-2 grams of plant-based protein per serving from the apples and applesauce. The cornstarch thickening provides a small amount of additional protein without fat.
For extra protein, I sometimes stir in 1 tablespoon vital wheat gluten (which adds about 3 grams of protein per tablespoon)—it's a secret trick I picked up from gluten-free baking.
Antioxidant Advantage
The combination of apples and cinnamon delivers a potent antioxidant punch. Apples contain quercetin and catechin, while cinnamon is rich in polyphenols. These compounds help combat oxidative stress in your body.
The lemon juice adds vitamin C, which enhances iron absorption if you're pairing this with a spinach salad or steel-cut oats for breakfast.
Blood Sugar Balance
This filling has a low glycemic index thanks to the fiber and natural sugars from apples. The cornstarch thickening helps slow sugar absorption compared to recipes using white flour. I've noticed my energy levels stay steadier when I eat this instead of traditional pie fillings—no sugar crash after dessert!
The nutmeg also helps regulate blood sugar by improving insulin sensitivity.
Heart-Healthy Swaps
By replacing butter with applesauce and olive oil, you're eliminating 90% of the saturated fat found in classic fillings. The olive oil provides heart-healthy monounsaturated fats instead. This swap reduces LDL cholesterol while maintaining the rich mouthfeel.
I've had cardiologists tell me this is one of the best dessert swaps for heart health—it's that effective. 💪

Frequently asked questions
Can I use other apples besides Granny Smith?
While Granny Smiths provide that perfect tartness, you can use Fuji, Honeycrisp, or Braeburn apples for a sweeter flavor. Just reduce the sugar to 2 tablespoons instead of ¼ cup since these varieties are naturally sweeter. For a mix of textures, try 1 Granny Smith with 3 Honeycrisp—you'll get the best of both worlds.
How do I make this filling extra thick for a pie?
If your filling seems too thin, add 1 more tablespoon of cornstarch and simmer for an additional 2-3 minutes while stirring constantly. For an instant fix, mix 1 teaspoon cornstarch with 1 tablespoon cold water, stir into the filling, and cook for 1 more minute. Pro tip: Always let the filling cool completely before adding to your pie crust—it thickens as it cools!
Can I make this filling ahead of time?
Yes! Store the cooled filling in an airtight container in the fridge for up to 5 days or freeze for 3 months. Thaw overnight in the fridge before using. The texture actually improves after chilling—it becomes even thicker and more flavorful. Perfect for meal prep! For pies, you can even freeze the filling directly in the crust (unbaked) for 2 months.
What's the best way to use this filling without a pie crust?
Try these creative options: Spoon over Greek yogurt or cottage cheese for a protein boost, layer between low-fat graham crackers for hand pies, or serve with baked apples. It also makes a fantastic topping for oatmeal or pancakes—just warm it slightly to release the flavors. The possibilities are endless!
Why does my filling taste bland?
Most likely, you need more spices or acid. Boost flavor by adding ½ teaspoon more cinnamon or a splash of lemon juice. For depth, try ¼ teaspoon cardamom or a pinch of allspice. The applesauce can also mute flavors—try reducing it to ¼ cup if you prefer stronger apple taste. Always taste as you go!
