Preparing Roast Potatoes for the Freezer
To freeze roast potatoes perfectly, you need to take a few steps before bagging them up. With the right prep, your roasties will freeze well and taste delicious when reheated later on.
Choose the Right Roast Potatoes to Freeze
The best roast potatoes to freeze are those that are:
- Fully cooked and cooled: Freeze roast potatoes once they’ve finished cooking and have cooled down. Freezing them hot can make them mushy.
- Dry and crispy: Roast potatoes freeze better when they have a crispy texture. Avoid freezing undercooked or soggy roast potatoes.
- Unsalted: Don’t add salt before freezing, as this can change the texture. Salt them after reheating instead.
- Plain, seasoning- or sauce-seasoned roast potatoes don’t freeze as well. Keep them plain for the best results.
Cut larger roast potatoes down to size.
If you have whole or large roast potato pieces, cut them down into smaller, evenly-sized pieces before freezing. This helps them freeze quicker and cook more evenly when reheated.
Aim for bite-sized pieces about 2 inches (5 cm) in size.
Spread Them Out to Cool
Avoid freezing roast potatoes in a big clump. Spread them out evenly in a single layer on a baking tray or plate. Allow them to cool completely; this helps remove excess moisture.
Some people recommend blanching cooked roast potatoes briefly in boiling water before freezing.
- Bring a pot of water to a boil.
- Add the roasted potatoes and blanch for 1 minute only.
- Drain and allow it to dry before freezing.
Blanching can help seal in flavor and texture. However, it’s not strictly necessary.
Once your roast potatoes are prepared, it’s best to freeze them right away. Leaving them to sit around can cause them to become soggy.
Freeze within 2 hours of cooking for the best quality.
Storing and packaging frozen roast potatoes
Now it’s time to stash those spuds away in the freezer! Here are some tips for packaging and storing them correctly:
Use freezer bags or containers.
The best way to store frozen roast potatoes is in freezer-safe bags or airtight containers. This prevents freezer burns.
- Use heavy-duty plastic freezer bags and press out excess air before sealing.
- Alternatively, store in rigid freezer-proof containers with tight-fitting lids.
Portion the potatoes.
Package your roast potatoes in usable portions for future meals. That way, you can just grab a bag or container when needed.
Handy portions for 2–4 people include:
- 500g/1 pound
- 650g-750g/11⁄2 pounds
- 1kg/2 pounds
Label with date and contents
Clearly label each bag or container with the contents and date frozen. This lets you use the oldest ones first.
Utilize freezer space.
Arrange packages flat in your freezer so they freeze quickly. Once solid, you can stack them on top of each other.
Place the roasted potatoes towards the back of the freezer, where the temperature is most consistent.
Maximum Freezing Time
Your well-wrapped roasties can be kept frozen for up to 12 months.
For best quality and texture, try to use within 3-6 months.
Reheating Frozen Roast Potatoes
One of the biggest keys to good frozen roasties is properly reheating them. With a bit of time and technique, you can revive them to crispy, flavorful perfection again.
Here are some reheating methods to try:
Oven (best method)
Reheating frozen roast potatoes in the oven produces the crispiest results.
- Preheat the oven to 400°F/200°C.
- Place frozen potatoes on a baking tray lined with parchment.
- Drizzle potatoes with oil and season with salt, pepper, herbs, etc.
- Cook for 15–25 minutes, tossing halfway, until hot and crispy.
You can also crisp up frozen roast potatoes nicely in a hot skillet with some oil.
- Heat 1-2 tablespoons of olive oil or butter in a large non-stick frying pan over medium-high heat.
- When it is hot, add the frozen potatoes in a single layer.
- Fry for 8–12 minutes, tossing frequently, until browned and sizzling.
An air fryer gives great crispy results too.
- Preheat the air fryer to 400°F/200°C.
- Add potatoes to the fryer basket in a single layer.
- Cook for 7–10 minutes until hot and crispy; shake the basket halfway.
Gravy or sauce
Add some extra flavor when reheating by tossing the potatoes with gravy or sauce. Try beef, pork, turkey gravy, or cheesy sauce.
The starch from the potatoes will help thicken the gravy deliciously.
Stews, Curries, or Fries
For a different flavor, you can use frozen roast potatoes in stews or curries, or turn them into home fries by cooking them with onions and bell peppers.
Get creative with reheating methods to enjoy your roasties in fun, new ways!
Handy Tips for Frozen Roast Potato Success
Follow these handy tips and tricks for the best results with your frozen roast potatoes:
- Let the potatoes thaw slightly before reheating—around 10 minutes at room temperature. This prevents overcooking.
- Reheat roasties from frozen within 3 months for ideal texture and taste.
- Double-check that the potatoes are piping hot throughout before eating.
- Don’t re-freeze potatoes once defrosted. Cook within 24 hours.
- For extra crunch, roast potatoes from frozen on the top oven rack.
- Preheat the oven, skillet, or air fryer before cooking to quickly crisp the potatoes.
- Brush potatoes with a little oil or melted butter before and during reheating.
- Fluff and shake potatoes during reheating to evenly brown.
- If reheated potatoes stick together, break them apart gently while still frozen.
- Add any extra seasonings or herbs after reheating for the best flavor.
Follow these tips, and your reheated roast potatoes will taste nearly as good as the freshly made ones!
