Freezing baked oatmeal is a great way to meal prep breakfast and enjoy a quick, nutritious prepped breakfast any day of the week. Whether you like baked oatmeal plain or loaded with toppings, here are four easy methods to freeze your baked oats, keeping them fresh and ready to go whenever you need them (I've even included a video to help)!

Freezing Tips
Cool. Always let your baked oatmeal cool completely before freezing. This will help prevent sogginess and maintain best texture.
Label. Label the wraps or bags with the date so you know when they're made. If freezing with baking paper, aluminum or ziplock bags, they will last around 3-6 months. The vacuum seal will last longer at around 6-12 months.
Reheat. Reheat in the microwave, oven or Air Fryer (more tips in the FAQs below), or you can defrost overnight and eat them cold.
Baking Paper
One of the easiest ways to freeze baked oats is by using baking paper. Simply slice your baked oats into portions, then place in the middle of the paper and wrap one way - leaving the sides out. Cut any extras from the sides so there's only 1-2 inches remaining, then tuck the sides in to ensure there's no gaps.
This method is perfect for a quick grab-and-go breakfast, and it prevents the oatmeal from sticking to the packaging. For extra protection, you can place the wrapped portions in a freezer-safe container or ziplock bag.
When you're ready to enjoy them, just unwrap and reheat in the microwave or oven! You could also let them thaw overnight in the fridge and eat them cold.
Aluminum Foil
Another option for freezing baked oatmeal is wrapping in aluminum foil. The
foil provides a solid barrier against freezer burn and helps retain moisture,
keeping your oats soft and flavourful. For best results, I suggest ripping a larger portion than what you think you'll need so some will overlap providing extra protection.
Just like with baking paper, you can store the wrapped oats in a container or freezer-safe bag for extra protection. When reheating, you can pop them directly into the oven still wrapped in foil for a crisp, freshly baked texture!

Ziplock Bag
Ziplock bags are a staple in most households and are useful when freezing baked oats.
Place your baked oatmeal portion in a small Ziplock bag (just enough for one serve), ensuring you squeeze out as much air as possible before sealing. This reduces the chance of freezer burn and keeps your baked oats tasting fresh.
Be sure to label with the date to keep track of how long they've been frozen.
Vacuum Sealing
For the longest-lasting freshness, vacuum sealing baked oats to freeze is the ultimate choice. This method removes all the air from around your baked oatmeal, creating an airtight seal that protects them from moisture and freezer burn.
Vacuum sealing helps retain the texture and flavour of the oats for a longer period, making it perfect for large batches of meal prep. When you're ready to eat, simply cut open the vacuum-sealed bag and heat up your oats in the oven or microwave.

FAQs
Reheating frozen baked oatmeal is easy and can be done using several methods depending on your preference:
Microwave: Place the frozen portion of baked oatmeal on a microwave-safe plate. Microwave on high for 1-2 minutes, checking halfway through to ensure it's evenly heated. If it’s not warm enough, continue heating in 20-30 second intervals.
Oven: For a crispier texture, you can reheat it in the oven. Preheat the oven to 180°C (350°F), place the frozen oatmeal on a baking sheet or in an oven-safe dish, and heat for 10-15 minutes until warmed through.
Air Fryer: If you like a little crisp, you can reheat the oatmeal in an air fryer at around 160°C (320°F) for 5-7 minutes. This method keeps the outside slightly crispy while warming the inside perfectly.
Absolutely! Freezing baked oatmeal is a great way to meal prep and ensure you always have a nutritious breakfast ready. Here’s why you should freeze baked oatmeal:
Convenience: Freezing portions of baked oatmeal allows you to grab and reheat a portion on busy mornings without the hassle of making a fresh batch.
Longer Shelf Life: Baked oatmeal lasts 3-5 days in the fridge, but it can be stored in the freezer for up to 3-12 months (depending on the freezer method used), which helps reduce waste.
Nutritional Benefits: Freezing preserves the nutrients and flavor of the baked oats, so you still get all the benefits of a freshly baked batch when you reheat them.
Cool Completely: Make sure your baked oatmeal has cooled fully before freezing to avoid excess moisture and sogginess.
Portioning: Slice the baked oatmeal into individual servings. This makes it easier to reheat just the amount you need.
Choose a Freezing Method:
1. Baking Paper: Wrap each portion in baking paper, tucking the sides in to prevent air exposure.
2. Aluminum Foil: Double-wrap each portion in foil to protect against freezer burn.
3. Ziplock Bags: Place portions into a Ziplock bag, squeeze out any air, and seal tight.
4. Vacuum Sealing: For the longest-lasting freshness, use a vacuum sealer to remove all the air.
Label and Store: Label your wrapped portions with the date and place them in the freezer. Baked oatmeal can last up to 3 months in the freezer.
How to Reheat Baked Oatmeal:
1. Microwave: Place the frozen portion on a microwave-safe plate, heat for 1-2 minutes, and enjoy!
2. Oven: Preheat the oven to 180°C (350°F) and bake the portion for 10-15 minutes until heated through.
3. Air Fryer: Reheat the frozen oatmeal in the air fryer at 160°C (320°F) for 5-7 minutes for a crispier finish.
Freezing and reheating baked oatmeal is simple, making it a great option for meal prepping and saving time on busy mornings.
