You can warm up frozen pumpkin pie by baking it low and slow, and it’ll taste almost as good as fresh.
Whether it’s a leftover slice or a whole pie you froze after the holidays, warming up frozen pumpkin pie is easier than you think.
The key is to be gentle with the heat so the filling heats through without the crust burning or the custard turning rubbery.
In this post, we’ll walk through how to warm up frozen pumpkin pie in the oven, the microwave, and even an air fryer, plus how to keep it from drying out along the way.
Let’s get that pie back to its cozy, spiced best.
Why Warming Up Frozen Pumpkin Pie Works So Well
Warming up frozen pumpkin pie works because pumpkin pie freezes beautifully, and a little gentle heat brings back that fresh-from-the-oven feel.
Here’s why it holds up so well.
1. The Custard Thaws Evenly With Low Heat
Pumpkin pie filling is a custard made from pumpkin puree, eggs, and milk or cream.
When you warm up frozen pumpkin pie slowly, the custard thaws evenly instead of cooking on the edges while staying cold in the middle.
Low and steady heat is what makes warming frozen pumpkin pie turn out smooth rather than grainy.
2. The Crust Can Crisp Back Up
A frozen pie crust can taste a little soft or soggy after freezing.
But when you warm up frozen pumpkin pie in the oven, the crust has a chance to crisp back up and regain some of its original texture.
That’s one big reason oven warming is the favorite method for bringing frozen pumpkin pie back to life.
3. The Spices Wake Back Up
Cinnamon, nutmeg, ginger, and cloves lose some of their punch when a pie sits in the freezer.
Warming up frozen pumpkin pie releases those warm aromas again, so each slice tastes as fragrant as it did on day one.
It’s a small thing, but it makes a big difference when you’re warming frozen pumpkin pie for guests.
How to Warm Up Frozen Pumpkin Pie in the Oven
The oven is the best way to warm up frozen pumpkin pie if you want that fresh-baked flavor and texture.
Here’s how to do it step by step.
1. Thaw It First (or Bake From Frozen)
If you have time, thaw the pie in the fridge overnight before warming frozen pumpkin pie.
If you’re short on time, you can warm up frozen pumpkin pie straight from the freezer, but add about 10 extra minutes to the bake time.
2. Preheat to a Low 300°F
Low heat is the secret to warming up frozen pumpkin pie without overcooking the eggs in the custard.
Skip higher temperatures, since they’ll brown the crust too fast while the middle stays cold.
3. Cover the Crust With Foil
Tent a little foil around the edges of the crust to protect it while you warm up frozen pumpkin pie.
This keeps the crust from over-browning while the filling heats all the way through.
4. Bake Until Warm in the Center
For a thawed pie, about 15–20 minutes usually does it.
For a frozen pie, plan on 25–35 minutes.
You’ll know your frozen pumpkin pie is warmed through when the center feels warm to the touch or reads about 140°F on a thermometer.
Other Ways to Warm Up Frozen Pumpkin Pie
No oven? No problem.
There are a couple of quicker ways to warm up frozen pumpkin pie when you’re craving a slice right now.
1. The Microwave Method
Place a single slice on a microwave-safe plate and heat it in 20-second bursts.
This is the fastest way to warm up frozen pumpkin pie, but go slow so the crust doesn’t get chewy.
A whole frozen pumpkin pie can be microwaved too, but use the defrost setting first, then short bursts of heat.
2. The Air Fryer Trick
An air fryer is great for warming up frozen pumpkin pie slices.
Set it to 300°F and warm the slice for 5–8 minutes, checking halfway.
The hot air circulates around the slice, so warming frozen pumpkin pie this way gives you a crisp crust and a warm center in minutes.
3. Keep It From Drying Out
No matter which method you use to warm up frozen pumpkin pie, cover it loosely with foil if the top starts looking dry.
A small dish of water in the oven also adds moisture while you’re warming frozen pumpkin pie and keeps the custard silky.
Tips for Warming Frozen Pumpkin Pie Perfectly
Here are a few extra pointers to keep in mind.
1. Don’t Refreeze After Warming
Once you warm up frozen pumpkin pie, eat it within a day or two.
Refreezing a warmed pie affects the texture and isn’t recommended for food safety.
2. Serve It Slightly Warm, Not Hot
Pumpkin pie tastes best when it’s just warm, around 100–110°F.
If you overheat frozen pumpkin pie, the custard can start to weep or separate, so pull it out a little early and let it rest.
3. Add Toppings After Warming
Whipped cream, ice cream, and caramel drizzle should go on after you warm up frozen pumpkin pie.
That way your toppings stay cool and creamy while the pie underneath is perfectly warm.
So, How Do You Warm Up Frozen Pumpkin Pie?
You warm up frozen pumpkin pie by using low, gentle heat, whether that’s in the oven, the microwave, or an air fryer.
The oven gives you the best texture, the microwave is fastest, and the air fryer is perfect for single slices.
The key to warming up frozen pumpkin pie is patience with the temperature so the custard stays smooth and the crust stays crisp.
Follow these steps, and your frozen pie will taste like it just came out of the oven.
