Pumpkin pie filling, cooked on its own in a slow cooker until it sets into something between a pie and a pudding.
No pastry to blind bake, no oven, and it is naturally gluten-free without substituting anything.
Why This Recipe Works
- Cornstarch instead of a pastry case does the structural work, so the pudding sets firm enough to scoop while staying soft.
- Evaporated milk brings richness without the extra water of regular milk, which matters when nothing is evaporating off in a covered cooker.
- A slow cooker on Low holds a gentle, even heat — closer to a water bath than an oven, which is exactly what a custard wants.
- 175°F is the number to trust. Custard sets by temperature, and a visual check alone will have you cooking it well past where it needed to stop.
The Whisking Order
This is a custard, and a custard is made or ruined in the order things go into the bowl. Each rung depends on the one below it.
AerateUntil slightly pale
Eggs whisked with both sugars until smooth and slightly pale. Sugar dissolving into egg is what gives the finished pudding its fine texture, and it cannot happen later once the mixture is cold and thick.
DiluteUntil fully combined
Pumpkin puree, evaporated milk, vanilla, pumpkin pie spice, cinnamon and salt whisked in. Adding the bulk now, into an already-smooth egg base, is what keeps the spice evenly dispersed rather than sitting in pockets.
Enrich and thickenUntil no lumps remain
Melted butter and cornstarch last, whisked until no lumps remain. Cornstarch added to a thin liquid disperses; cornstarch added to thick puree clumps and stays clumped through three hours of gentle heat.
SetLOW 3-4 hours, or HIGH 1.5-2.5
Poured into the cooker under a towel-lined lid and cooked on Low 3 to 4 hours, until the edges are set and the centre jiggles slightly at about 175°F.
Finish off the heat20-30 minutes
Twenty to thirty minutes covered with the cooker off. The residual heat carries the centre the rest of the way, which is gentler than leaving it on and risking the edges.
Ingredient Notes
- Evaporated milk
- Full-fat coconut milk is the dairy-free swap, and it sets just as well. Regular milk is thinner and gives a softer, wetter pudding.
- Cornstarch
- Three tablespoons, and the only thickener. Added last into an already-thin mixture so it disperses rather than clumping.
- Eggs
- Two, or two flax eggs for a vegan version — step 2 adjusts for that swap. Flax gives a slightly denser set.
- Pumpkin pie spice
- Two teaspoons, plus a further half teaspoon of cinnamon on top. The extra cinnamon is deliberate; it pushes the blend warmer than the jar alone.
How to Make It
Prepare the cooker
Grease a 4- to 6-quart insert, and line the base with a parchment sling if you want to lift the pudding out.
Whisk eggs and sugars
In a large bowl, whisk the eggs with the brown and granulated sugars until smooth and slightly pale.
Add the pumpkin and milk
Whisk in the puree, evaporated milk, vanilla, pumpkin pie spice, cinnamon and salt until fully combined.
Add butter and cornstarch last
Whisk in the melted butter and the cornstarch until no lumps remain.
Cook on Low
Pour into the cooker, lay a clean kitchen towel under the lid, and cook on LOW 3 to 4 hours (or HIGH 1.5 to 2.5), until the edges are set and the centre jiggles slightly at about 175°F.
Rest before serving
Turn the cooker off and let it stand, covered, 20 to 30 minutes to finish setting.
Serve
Scoop into bowls, warm or chilled, with whipped cream, Greek yogurt, ice cream or toasted pecans.
Success Tips
- Use a thermometer. Edges set long before the centre, and 175°F is a far better guide than the clock in a cooker you may not know well.
- The towel under the lid is not optional in practice. Condensation dripping onto a custard leaves watery patches on top.
- Whisk the cornstarch in thoroughly. Any lump you can see now will still be there in three hours.
- Let it rest the full twenty minutes. Scooping straight away gives a looser pudding than the recipe is aiming for.
Serving Ideas
Warm with whipped cream is closest to pie; chilled and firm with Greek yogurt eats more like a set custard. Toasted pecans add the only crunch in the bowl.
Storage and Reheating
Refrigerate
Refrigerate covered up to 4 days. It firms as it chills and is very good cold.
Freeze
Not recommended. A cornstarch-set custard weeps on thawing and the texture does not recover.
Reheat
Warm individual portions gently in the microwave in short bursts. Avoid a hard reheat, which can split the custard.
Frequently Asked Questions
Can I make it dairy-free?
Yes — use full-fat coconut milk in place of evaporated milk, and vegan butter or none at all. The set comes from the eggs and cornstarch, so it holds up.
Can I make it without eggs?
Use two flax eggs, whisked with the sugars until thickened. Expect a slightly denser, less delicate set, since the eggs contribute some of the lift as well as the structure.
Why is there liquid on top?
Usually condensation, which is what the towel under the lid prevents. It can also mean it cooked past its set point — custard held too long at heat squeezes out moisture.
