How long to reheat blueberry pie depends on your method, but most pies take about 15 to 25 minutes in a 350°F oven.
If you’re wondering how long to reheat blueberry pie without drying out the crust or turning the filling into a runny mess, the answer comes down to using the right technique and the right temperature.
The good news is that reheating blueberry pie is simple once you know a few key rules.
In this post, we’ll cover exactly how long to reheat blueberry pie in the oven, microwave, and air fryer, plus tips to keep that flaky crust and juicy filling tasting fresh.
Let’s get into it.
How Long to Reheat Blueberry Pie in the Oven
Reheating blueberry pie in the oven is the best way to bring back that fresh-baked taste, and it usually takes 15 to 25 minutes at 350°F.
The oven gives you even heat, which warms the filling all the way through while keeping the crust crisp instead of soggy.
Here’s how to nail it every time.
1. Preheat to 350°F
Set your oven to 350°F and let it fully preheat before the pie goes in.
A properly heated oven is the secret to knowing how long to reheat blueberry pie, because a cold oven stretches the time and dries out the crust.
2. Cover the Crust if It’s Browning
If your crust is already golden, tent it loosely with foil to stop it from burning.
This matters when you reheat blueberry pie that was baked a day or two ago, since the edges can darken fast.
3. Bake for 15 to 25 Minutes
A single slice takes about 10 to 15 minutes, while a whole pie needs closer to 20 to 25 minutes.
You’ll know it’s done when the filling starts to bubble at the edges and the center feels warm.
How Long to Reheat Blueberry Pie in the Microwave
If you’re in a hurry, reheating blueberry pie in the microwave takes just 30 to 60 seconds per slice.
The trade-off is that the crust softens instead of crisping, but it’s perfect for a quick craving.
Here’s how to do it right.
1. Use a Microwave-Safe Plate
Place your slice on a microwave-safe plate and cover it with a damp paper towel.
The towel traps steam so the filling heats evenly without splattering all over your microwave.
2. Heat in 30-Second Bursts
Microwave on high for 30 seconds, then check.
If you’re reheating blueberry pie and it’s still cold in the middle, add another 15 to 30 seconds.
Going in short bursts keeps the filling from turning into lava.
3. Crisp the Crust Afterward
Want the best of both worlds?
Microwave the slice first, then pop it in a toaster oven for 3 to 5 minutes at 350°F.
This trick gives you a fast reheat with a crust that still has some bite.
How Long to Reheat Blueberry Pie in an Air Fryer
An air fryer reheats blueberry pie in about 5 to 8 minutes at 320°F, and it keeps the crust surprisingly crisp.
This is a great middle ground when you want speed without sacrificing texture.
1. Set the Temperature to 320°F
Air fryers run hot, so a slightly lower temperature prevents the crust from burning before the filling warms.
This is the key detail when figuring out how long to reheat blueberry pie in an air fryer.
2. Reheat for 5 to 8 Minutes
A single slice needs about 5 minutes, while two slices may take 7 to 8 minutes.
Check halfway through and rotate if your air fryer cooks unevenly.
3. Watch for Bubbling Filling
When the blueberry filling starts to bubble, it’s ready.
That bubbling is your signal that you’ve reheated blueberry pie to the perfect temperature inside and out.
Tips for Reheating Blueberry Pie Without Ruining It
Knowing how long to reheat blueberry pie is only half the battle.
These extra tips keep your pie tasting like it just came out of the bakery.
1. Never Reheat at High Heat
High heat makes the crust burn while the filling stays cold.
Stick to 350°F in the oven and 320°F in the air fryer for the best results.
2. Add a Little Butter or Egg Wash
Brushing the crust with a bit of melted butter or egg wash before reheating helps it regain that glossy, flaky finish.
It’s a small step that makes a big difference when you reheat blueberry pie.
3. Let It Rest Before Serving
Give the pie 5 minutes to rest after reheating.
The filling thickens as it cools slightly, so it won’t run all over the plate when you slice in.
4. Store Leftovers Properly
Keep leftover pie covered in the fridge for up to 3 days.
Proper storage means the next time you reheat blueberry pie, it’ll still taste fresh and juicy.
5. Freeze for Longer Storage
If you need more time, freeze slices wrapped tightly in plastic and foil for up to 2 months.
Then reheat blueberry pie straight from frozen by adding about 10 extra minutes in the oven.
So, How Long to Reheat Blueberry Pie?
How long to reheat blueberry pie comes down to your method: 15 to 25 minutes in the oven, 30 to 60 seconds in the microwave, or 5 to 8 minutes in an air fryer.
The oven gives you the classic fresh-baked result, the microwave is fastest, and the air fryer balances speed with a crisp crust.
No matter which route you choose, low and slow beats high heat every time.
Now you know exactly how long to reheat blueberry pie so every slice tastes as good as the first day.
