How To Cook A Frozen Pumpkin Pie

You can cook a frozen pumpkin pie without thawing it first, though the method depends on whether your pie is homemade or store-bought.
 
If you’re wondering how to cook a frozen pumpkin pie, the good news is that it’s pretty straightforward once you know whether it’s a pre-baked pie that just needs reheating or a raw, unbaked pie that needs full baking.
 
The approach changes based on which type you have, so let’s break it down so you get a perfectly warm, sliceable pie every time.
 
In this post, we’ll walk through how to cook a frozen pumpkin pie, whether you’re working with a homemade frozen pie or a store-bought one, and share tips to keep that custard smooth and the crust crisp.
 
Let’s get into it.

How to Cook a Frozen Pumpkin Pie: The Basics

Knowing how to cook a frozen pumpkin pie starts with identifying what kind of pie you actually have.
 
A fully baked frozen pumpkin pie just needs reheating, while an unbaked frozen pumpkin pie needs to go through the full baking process.
 
Getting this right is the difference between a silky, set custard and a soupy mess.

1. Check if Your Pie Is Pre-Baked or Unbaked

Before you cook a frozen pumpkin pie, look at the label or think back to how you froze it.
 
Store-bought frozen pumpkin pies are usually already baked, so you’re just warming them up.
 
If you froze a homemade pie with raw filling, that’s a different story and it needs to bake from frozen.

2. Never Thaw Before Baking an Unbaked Pie

Here’s a key tip for how to cook a frozen pumpkin pie that’s still raw: don’t thaw it first.
 
Thawing an unbaked pumpkin pie can make the crust soggy and the filling watery before it even hits the oven.
 
Baking it straight from frozen helps the crust set while the custard cooks evenly.

3. Preheat Your Oven Properly

Whatever type of frozen pumpkin pie you’re cooking, always preheat your oven fully.
 
A hot oven gives the crust a chance to crisp up before the filling starts steaming.
 
For an unbaked pie, aim for 375°F (190°C), and for a pre-baked pie you’re reheating, 350°F (175°C) works well.

How to Cook a Frozen Pumpkin Pie That’s Unbaked

If your frozen pumpkin pie is unbaked, here’s how to cook it so it turns out smooth and fully set.
 
This is the method to follow when you want to know how to cook a frozen pumpkin pie from scratch, straight from the freezer.

1. Place It on a Baking Sheet

Set your frozen unbaked pie on a rimmed baking sheet before it goes in the oven.
 
This catches any drips and makes it easier to move the pie in and out safely.
 
It also helps distribute heat evenly around the bottom of the crust.

2. Bake at 375°F for 60 to 75 Minutes

How long you cook a frozen pumpkin pie depends on its size and how cold it is.
 
Start checking around the 60-minute mark, but expect it to take up to 75 minutes.
 
The pie is done when the center is just slightly jiggly and a knife inserted near the edge comes out clean.

3. Shield the Crust if It Browns Too Fast

Since you’re cooking a frozen pumpkin pie for a longer time, the crust can darken quickly.
 
Tent the edges with foil or use a pie shield about halfway through baking.
 
This keeps the crust golden instead of burnt while the custard finishes setting.

4. Cool Completely Before Slicing

Once you’ve cooked your frozen pumpkin pie, resist the urge to cut into it right away.
 
The filling continues to set as it cools, so give it at least 2 to 3 hours on a wire rack.
 
This step is what gives you clean slices instead of a runny center.

How to Cook a Frozen Pumpkin Pie That’s Already Baked

If your frozen pumpkin pie is already baked, you’re really just reheating it to bring back that fresh-from-the-oven feel.
 
Here’s how to cook a frozen pumpkin pie that’s pre-baked without drying out the filling.

1. Thaw Overnight in the Fridge

For the best texture, move your baked frozen pumpkin pie to the fridge the night before.
 
This slow thaw keeps the custard creamy instead of rubbery.
 
If you’re short on time, you can reheat from frozen, but the results are slightly less smooth.

2. Reheat at 350°F for 15 to 20 Minutes

When you cook a frozen pumpkin pie that’s already baked, a short stint in the oven is all it needs.
 
Pop it in at 350°F until it’s warmed through, usually 15 to 20 minutes.
 
Cover the crust with foil if it’s already nicely browned.

3. Or Skip the Oven and Use the Microwave

In a hurry? You can cook a frozen pumpkin pie slice in the microwave for about 30 to 60 seconds.
 
It won’t bring back a crisp crust, but it gets the job done for a quick craving.
 
Just keep an eye on it so the filling doesn’t turn rubbery.

So, How Do You Cook a Frozen Pumpkin Pie?

You can cook a frozen pumpkin pie by baking it from frozen if it’s unbaked, or simply reheating it if it’s already baked.
 
The method you choose depends entirely on whether your pie went into the freezer raw or fully cooked.
 
For unbaked pies, bake at 375°F for 60 to 75 minutes and let it cool fully before slicing.
 
For pre-baked pies, thaw overnight and reheat at 350°F for 15 to 20 minutes.
 
Either way, knowing how to cook a frozen pumpkin pie means you’re never stuck when a craving hits or when the holidays sneak up on you.
 
Now you can pull that pie out of the freezer with confidence and serve a warm, delicious slice any time.
