Healthy Pumpkin Pie Low Sugar with an Almond Oat Crust
The spice blend is where pumpkin pie actually lives. Pumpkin on its own is mild and earthy. It is the cinnamon, ginger, cloves and nutmeg together that create the specific flavour profile every autumn food memory is built around. This lower-sugar version keeps the spice blend intact, because that is the non-negotiable part, while replacing the standard pastry crust with one made from oats and almond flour and reducing the sugar in the filling by using maple syrup and the natural sweetness of properly seasoned pumpkin puree. You still get the burnished amber surface, the smooth yielding interior and the warm spice hit that makes pumpkin pie worth making every year.
Why this recipe works
Pumpkin puree provides the body of the filling with minimal calories and a solid amount of fibre and beta-carotene. Coconut milk adds the creaminess that gives the filling its silky texture. Eggs bind everything together and create the slightly firm, sliceable set you need. The almond and oat crust is pressed into the tin rather than rolled, which removes the most stressful part of pie-making entirely. It bakes to a golden, crumbly edge that holds its shape cleanly when the pie is sliced.
Getting it right
Blind bake the crust for ten minutes before adding the filling. This prevents the base from going soggy during the long bake time. Press the crust evenly up the sides of the tin as well as across the base.
Temper the eggs into the warm filling mixture rather than adding them directly to a hot mixture. Add a spoonful of warm pumpkin to the beaten eggs and stir, then pour the egg mixture back into the pan. This prevents scrambling.
Common mistakes
Not seasoning the filling enough produces a flat, bland pie. Taste it before it goes into the crust and adjust the spices. The balance of cinnamon, ginger, cloves and nutmeg is worth getting right.
Overbaking produces a cracked surface and a grainy texture in the filling. The pie is done when the edges are set and the centre still has a slight jiggle.
Substitutions
Butternut squash puree works in place of pumpkin with a slightly sweeter, more delicate flavour. Sweet potato puree produces a denser, richer filling. Coconut milk replaces evaporated milk one-for-one for a dairy-free version.
Serving suggestion
Serve at room temperature rather than straight from the fridge, where the filling firms up and loses some of its silky texture. A small scoop of coconut cream on each slice adds elegance with minimal effort.
Ingredients
- 1.5 cups rolled oats (use certified gluten-free oats if needed)
- 1 cup ground almonds (also called almond flour or almond meal)
- 3 tablespoons coconut oil (melted and slightly cooled)
- 2 tablespoons pure maple syrup (for the crust)
- 0.3 teaspoon fine sea salt (for the crust)
- 425 grams pure pumpkin puree (one standard can, not pumpkin pie filling)
- 2 large eggs (at room temperature)
- 0.8 cup full-fat coconut milk (shake the can well before opening)
- 3 tablespoons pure maple syrup (for the filling)
- 1.5 teaspoons ground cinnamon
- 0.8 teaspoon ground ginger (freshly ground is even better)
- 0.3 teaspoon ground nutmeg
- 0.1 teaspoon ground cloves (a little goes a long way)
- 1 teaspoon pure vanilla extract
- 1 tablespoon arrowroot powder (helps the filling set firmly, cornstarch also works)
Instructions
- 1
Preheat your oven to 175 degrees Celsius (350 degrees Fahrenheit). Lightly grease a 9-inch pie dish with a small amount of coconut oil and set it aside.
Using a glass pie dish lets you check the base is browning evenly without lifting the pie out.
- 2
Add the rolled oats to a food processor and pulse for about 20 seconds until they resemble a coarse flour. Some larger flakes remaining is totally fine and adds texture.
- 3
Add the ground almonds, melted coconut oil, 2 tablespoons of maple syrup and the sea salt to the food processor with the oats. Pulse again until everything combines into a damp, crumbly dough that holds together when pressed between your fingers.
If the mixture feels too dry, add one teaspoon of cold water at a time and pulse briefly.
- 4
Tip the crust mixture into the prepared pie dish. Use your fingers and the back of a spoon to press it evenly across the base and up the sides, aiming for a thickness of about half a centimetre throughout.
Pressing the crust firmly is key. A loose crust will crumble when you slice the finished pie.
- 5
Bake the crust on its own for 10 to 12 minutes until it looks lightly golden at the edges. Remove from the oven and allow it to cool for 10 minutes while you prepare the filling.
- 6
In a large mixing bowl, whisk together the pumpkin puree, eggs, coconut milk, 3 tablespoons of maple syrup and the vanilla extract until smooth and fully combined.
Whisking by hand rather than using a blender keeps air out of the filling and reduces the chance of cracks forming on top.
- 7
Add the cinnamon, ginger, nutmeg, cloves and arrowroot powder to the pumpkin mixture. Whisk again until the spices and arrowroot are fully incorporated and no lumps remain.
Taste the raw filling here and adjust spices to your liking. This is the moment to make it your own.
- 8
Pour the pumpkin filling slowly and evenly into the pre-baked crust. Gently tap the pie dish on the counter twice to release any air bubbles near the surface.
- 9
Bake the filled pie for 38 to 42 minutes. The edges should look set and the very centre should still have a slight wobble when you gently shake the dish. It will continue to firm up as it cools.
If the crust edges are browning too quickly, loosely lay a strip of foil around the rim for the final 10 minutes of baking.
- 10
Remove the pie from the oven and allow it to cool completely at room temperature for at least one hour. Then transfer it to the refrigerator and chill for a minimum of two hours before slicing.
Chilling is not optional here. The filling needs this time to fully set. Overnight chilling gives the best, cleanest slices.

Pro Tips
- ✓
Use pure pumpkin puree, not pumpkin pie filling. The filling version already contains sugar and spices, which will throw off the balance of this recipe.
- ✓
Full-fat coconut milk creates a much creamier filling than the light version. Do not substitute low-fat here.
- ✓
Letting eggs come to room temperature before mixing helps them incorporate more smoothly into the pumpkin custard.
- ✓
The pie keeps its best texture when sliced cold, straight from the fridge. Let individual slices sit for five minutes before serving if you prefer a slightly warmer flavour.
- ✓
For extra warmth, add a pinch of black pepper to the spice mix. It sounds unusual but it amplifies the ginger beautifully.
- ✓
This recipe doubles well. Make two pies at once and freeze one for later in the season.
Frequently Asked Questions
Variations
- •
Chocolate Swirl Pumpkin Pie
Melt 2 tablespoons of dairy-free dark chocolate with 1 teaspoon of coconut oil. After pouring the pumpkin filling into the crust, drizzle the chocolate over the surface and use a toothpick to swirl it gently through the top layer. Bake as directed. The chocolate adds richness and only a small amount of extra calories.
- •
Spiced Pecan Topped Pumpkin Pie
Roughly chop a handful of pecans and toss them with half a teaspoon of cinnamon and a tiny drizzle of maple syrup. Scatter them over the pie filling before the final 15 minutes of baking for a crunchy, festive topping.
- •
Mini Pumpkin Pie Cups
Press the crust mixture into a greased 12-hole muffin tin instead of a pie dish, about 1 tablespoon per hole. Fill each cup with pumpkin mixture and bake at 175 degrees Celsius for 22 to 25 minutes. These are fantastic for parties and portion control.
- •
Crustless Pumpkin Custard
Skip the crust entirely and simply pour the pumpkin filling into a lightly greased pie dish or individual ramekins. Bake at 175 degrees Celsius for 30 to 35 minutes for ramekins or 40 minutes for a large dish. This version is even lower in calories and completely grain-free.
Substitutions
- •Full-fat coconut milk → Evaporated oat milk or evaporated skimmed milk (The texture will be slightly less rich but still sets well. Avoid thin plant milks like almond or rice milk as the filling may not firm up properly.)
- •Arrowroot powder → Cornstarch (Use in exactly the same quantity, 1 tablespoon. Both work as thickening agents to help the filling set cleanly.)
- •Ground almonds → Sunflower seed flour (Grind raw sunflower seeds in a food processor until fine. This makes the recipe nut-free without changing the texture significantly.)
- •Rolled oats → Buckwheat flakes (Buckwheat flakes are naturally gluten-free and give the crust a slightly earthier, nuttier flavour. Use in the same quantity.)
- •Coconut oil → Melted unsalted butter (Works well if dairy is not a concern for you. The crust will have a slightly richer, more traditional flavour.)
- •Pure maple syrup → Date syrup (Date syrup has a deeper, more caramel-like flavour and a slightly lower glycaemic impact than maple syrup. Use the same quantity.)
🧊 Storage
Cover the pie loosely with cling film or a reusable beeswax wrap and store in the refrigerator for up to 4 days. For freezing, slice the fully chilled pie and wrap individual slices in cling film, then place them in a zip-lock bag or airtight container. Freeze for up to 2 months. Thaw overnight in the refrigerator before serving.
📅 Make Ahead
This pie is an excellent make-ahead dessert. You can bake it up to two days in advance and store it in the refrigerator, covered. The flavour genuinely improves after 24 hours as the spices have time to meld into the filling. The crust can also be pressed into the dish and refrigerated unbaked for up to one day before you add the filling and bake.
