How to Reheat Lasagne: Step-by-Step for Perfect Results
Defrost in the fridge first, then oven bake at 180 degrees Celsius for golden, bubbly results every time.
The best way to reheat lasagne is to defrost it in the fridge first, then bake it in the oven at 180 degrees Celsius for 25 to 30 minutes. This produces evenly heated layers, a bubbly sauce and a golden, slightly crispy top that makes lasagne worth eating.
If you have a Providoor lasagne like Silvia Colloca's Classic Italian Lasagne ($32, serves 2), these instructions will give you the best possible result.
Step 1
Defrost in the Fridge (24 Hours Before)
Move your frozen lasagne from the freezer to the fridge at least 24 hours before you plan to eat it. Place it on a plate to catch any condensation. Lasagne is a dense, layered dish, so it needs the full 24 hours to defrost all the way through.
Do not defrost lasagne at room temperature or under running water. The outer layers will warm up while the centre stays frozen, which creates both food safety issues and uneven reheating.
A fully defrosted lasagne reheats evenly. This is the single most important step.
Step 2
Preheat Your Oven to 180 Degrees Celsius
Fan-forced ovens work best for lasagne. Preheat to 180 degrees Celsius. If you are using a conventional (non-fan) oven, set it to 190 degrees Celsius to compensate.
Step 3
Cover with Foil and Bake
Place the defrosted lasagne in its foil tray directly in the oven. Cover the top with aluminium foil.
Bake covered for 15 to 20 minutes. The foil traps steam and prevents the top from drying out or browning too quickly while the interior heats through.
Step 4
Remove Foil and Finish
After 15 to 20 minutes, remove the foil. Continue baking uncovered for another 10 to 15 minutes. This is what gives you that golden, bubbly top with slightly crispy edges along the sides.
The total reheating time is 25 to 30 minutes for a fully defrosted lasagne.
Step 5
Rest Before Serving
Take the lasagne out of the oven and let it rest for 3 to 5 minutes. This allows the layers to set slightly, making it easier to serve clean portions rather than a molten puddle. Lasagne always tastes better after a brief rest.
What About Reheating Lasagne from Frozen?
You can cook lasagne from frozen, but for best results we recommend defrosting first as this helps with even cooking. If baking from frozen, cover with foil and bake at 180 degrees Celsius for 30 to 45 minutes. Defrosted lasagne will give you more consistent layers and a better overall result.
For the best experience, plan ahead and defrost in the fridge.
Common Mistakes When Reheating Lasagne
Not defrosting first. The centre stays cold while the edges overcook. Always defrost in the fridge for 24 hours.
Skipping the foil. Without foil for the first stage, the top browns before the interior is hot. Cover first, then uncover.
Overheating. Lasagne is already fully cooked. You are just bringing it back to temperature. Keep the oven at 180 degrees Celsius, not higher.
Not resting. Cutting straight from the oven produces a messy serve. Three to five minutes of resting makes a noticeable difference.
Frequently Asked Questions
Should I defrost frozen lasagne before reheating?
Yes. Defrost in the fridge for 24 hours before reheating. A defrosted lasagne reheats evenly at 180 degrees Celsius in 25 to 30 minutes, with consistent texture through every layer.
What temperature should I reheat frozen lasagne at?
180 degrees Celsius for a fan-forced oven, or 190 degrees for a conventional oven. Cover with foil for the first 15 to 20 minutes, then uncover for the final 10 to 15 minutes.
How long does it take to reheat frozen lasagne in the oven?
A fully defrosted lasagne takes 25 to 30 minutes at 180 degrees Celsius. If baking from frozen (not recommended), allow 30 to 45 minutes covered with foil.
How do I know when reheated lasagne is ready?
The sauce should be bubbling, the top should be golden, and the internal temperature should reach 75 degrees Celsius. Let it rest for 3 to 5 minutes before serving.
