If you’re a long time follower of Budget Bytes, you know that my freezer is my best friend. I use it to freeze leftover ingredients, leftover portions of cooked meals, and to stock up on sale items like cheese and meat. But I’ve also come to realize that there is a large grey area when it comes to freezing food. There is no clear line dividing foods that freeze well and those that don’t and there is no definitive cut off date for when frozen foods go from good to bad. That being said, I wanted to write a tutorial about how I freeze leftovers to give you a jumping off point, or a place to start experimenting with freezing food for yourselves. …Because it will take experimentation. Experimentation to find which methods produce results that you’re happy with and how to balance the effort with the savings in your own kitchen.
In this tutorial I’ll provide you with links to reputable resources for information about freezing food, the methods that I use to freeze my leftover meals and ingredients, as well as a nifty little printable chart I developed to keep track of the leftovers in my freezer.
Tomorrow, I’ll round up my favorite recipes that make great “freezer leftovers.”

The most comprehensive information that I’ve found surrounding freezing food comes from the FDA and the National Center for Home Food Preservation. They’ve done far more research than I have (obvi) and have compiled the information into clear and concise charts and FAQs. So, read these first or at least bookmark them for future reference:

What Freezes Well?
That’s the question of the hour, my friends. Unfortunately, there is no definitive answer. Food undergoes a number of changes during the freeze/thaw process, and some people are more sensitive to those changes than others. Ice crystals, dehydration (aka freezer burn), and enzymes can all produce changes in the texture, appearance, and flavor of food that is stored in the freezer. These changes and how much they bother you is what makes freezing so subjective and will require your experimentation. Below are some general lists of what I think freezes well and what doesn’t.
Do Freeze: soups, stews, casseroles, saucy pasta and rice dishes, raw meat or seafood, broth, bread, cookies, baked goods, tortillas, cheese (grated or in block form), tomato paste, pesto, buttermilk, butter, ginger, cooked beans, cooked rice or pasta, fresh fruit for smoothies or baking, vegetables for soups or stews.
Do Not Freeze: cream sauces, custards, high water content vegetables (like lettuce, cucumber, tomato), sour cream, mayonnaise, fried foods, anything with gelatin.
Eggs are an item that rests comfortably in the middle. Raw eggs can be frozen if taken out of the shell, but cooked eggs tend to seep water and get over cooked when reheated. I have frozen quiches and other egg dishes with success, but I suspect not everyone would be as happy with the results as I was.

My goals when freezing food are to avoid freezer burn, to make the food reheatable in the portions that I need, AND to make sure the food is identifiable in a sea full of frozen foods. So, when I freeze food I ask myself: How can I package this to reduce air exposure? What portion and I likely to use or eat of this food in the future? and Is it labeled?
I start with portioning because that happens before the food is wrapped up. I tend to freeze pieces of meat individually, so that I can thaw as little as one at a time if needed. Leftover cooked food gets frozen in individual serving size containers, so that I can reheat one meal at a time (like a homemade TV dinner!). Cooked beans, rice, or pasta usually gets frozen in 2 cup portions (or close to the volume of one can of beans) because that’s usually about how much I’ll use in a recipe. Tomato paste, pesto, or buttermilk get frozen in 1-2 Tbsp portions. The goal of portioning is to avoid thawing all of your frozen stash when you only need to use a little. Repeated thawing and refreezing drastically reduces quality and creates many more opportunities for food safety risks.

Reducing air exposure is key to preventing freezer burn and maintaining the foods’ appearance and quality. So, it’s important to use heavy duty, freezer grade products. Regular plastic wrap and original food packaging may be air permeable and won’t protect against dehydration well. So, my go-to items are quart and gallon sized freezer bags and reusable Ziploc containers (similar freezer, microwave, and dishwasher safe containers are also made by other brands).
(Containers of frozen soup and sauce from my freezer, ready to go straight into the microwave for reaheating.)
I use the hard sided Ziploc containers to store leftover portions of soups, stews, and casseroles. I like the containers for pre-portioned meals because they can go straight from the freezer to the microwave, without the need for dirtying more dishes.
Freezer bags are my favorite because you can squeeze out the excess air from around the food. For irregular shaped foods, I often wrap them in an extra layer of plastic within the freezer bag (or rewrap in the original packaging and place within a freezer bag), just to further reduce air flow around the food.
And lastly, make sure to label and date the food when possible (like, always if you can). Most freezer bags come with an area that can be written on with a Sharpie, but good old fashioned masking tape works well, too. You’ll find rolls of masking tape in just about every commercial kitchen where it is critical to label and date every food item.
Tips for Freezer Success
- Chill the food completely in the refrigerator before freezing. This makes smaller ice crystals and less textural damage to the food.
- For small items (like meatballs, cookie dough, or fruit pieces), freeze while spread out on a baking sheet, then transfer to a freezer bag once solid. This prevents the pieces from clumping.
- Make sure there is room for air to flow in the freezer, which will help maintain proper temperatures.
- Label and date your food. LABEL AND DATE YOUR FOOD.
- Freeze in smaller portions when possible. This makes foods freeze faster and reduces the need to thaw more food than needed.
- “Shop” your freezer on a regular basis to stay on top of your inventory.
Free Downloadable Freezer Chart
I made this cool little chart that you can use to keep track of the leftovers you’ve frozen. This chart will help you eat your leftovers in a timely manner (before they have a chance to get freezer burn) and it will act as an “in your face” reminder of all the delicious food you have ready and waiting to be eaten at home (a take-out deterrent!).
To use this chart, simply write the name of the recipe and the date it was frozen. Next, draw a circle or square around the number of portions that you’ve frozen. Hang the chart on your fridge and every time you eat a portion, simply cross one of the portions off. Now you have a quick visual reference of your frozen meals, without having to rummage through the freezer or get numb finger tips!
Thawing, like freezing, is often food specific. The safest way to thaw is to simply plan ahead and transfer the food to the refrigerator one day ahead. This will keep the food within a safe temperature (below 40ºF) while still allowing the food to slowly thaw. For leftovers of cooked food (like my soups, stews, rice or pasta dishes), I often just reheat them in the microwave straight from the freezer with no thawing. Bread, pastries, and other baked goods that are normally stored at room temperature can be thawed at room temperature. Because of the light, airy texture of bread, it thaws very quickly at room temperature, or can be placed straight into the toaster from the freezer. If you have frozen soups, sauces, or other liquid substances in a freezer bag, simply cut the bag away and place the frozen block into a sauce pot. Reheat the liquid over low heat with a lid (to prevent dehydration), while stirring often.

Freezing leftover food and ingredients can save you a LOT of cash (and hard work), so it’s worth learning how to do and getting comfortable with the process, but there is a learning curve. When in doubt, throw it out. A medical bill is almost always going to be more expensive than the few dollars you saved by not throwing away that questionable food. ;)
