I feel like my family has a very hard time predicting how much milk we’re going to consume in any given week.
Some weeks, I buy what I think is enough milk to get us through several days, only to discover that somehow, everyone has gone through it in what feels like two seconds. Between cereal at breakfast, coffee in the morning, cooking, baking, and the occasional glass of milk, that gallon can disappear before I even realize it.
Other weeks, I buy more milk because I’m convinced we’re going to need it, and then… nobody touches it.
Suddenly, the expiration date is approaching, there’s still half a gallon sitting in the refrigerator, and I’m trying to figure out what I can possibly make with all of it.
If this sounds familiar, I have some good news: you can freeze milk!
I honestly had no idea this was an option for a long time. I always assumed that milk was one of those foods that simply had to stay in the refrigerator until you used it. But freezing milk can be a surprisingly simple way to help prevent waste, save money, and make sure you have milk available when you need it.
There are a few important things to keep in mind, though. You can’t just toss a completely full container into the freezer and forget about it. Milk expands as it freezes, so you need to leave some room for that expansion. You’ll also want to think about how you plan to use the milk after it thaws.
Here’s everything you need to know about freezing milk.
How to Safely Freeze Milk
The first thing to know is that freezing milk is pretty straightforward, but you need to give it room to expand.
My Heavenly Recipes has shared tips for freezing milk that comes in plastic gallon containers. If you have a completely full gallon of milk, you’ll want to pour approximately one cup out before putting the container in the freezer.
Why?
Because milk expands when it freezes.
If you put a completely full jug into the freezer, the expanding liquid can put pressure on the container. In the best-case scenario, you may end up with a misshapen jug. In the worst-case scenario, you could wind up with a messy frozen milk explosion inside your freezer.
And nobody wants to discover that first thing in the morning.
So, before freezing a gallon of milk, remove enough milk to leave some empty space at the top. You can drink it, use it in a recipe, or simply pour a small amount into another container.
Once you’ve made some room, make sure the lid is securely closed. Then place the jug upright in your freezer where it won’t get knocked over.
It’s also a good idea to freeze the milk before it reaches its expiration date. Freezing doesn’t magically reset the freshness of milk, so starting with milk that is already old isn’t going to give you the best results.
What Kind of Container Should You Use?
This is an important detail.
If you’re planning to freeze milk in its original container, plastic jugs are the easiest option. Glass containers can crack or break when exposed to the extreme temperature change of the freezer, so you generally don’t want to take a full glass bottle of milk and stick it directly into the freezer.
If you’re transferring milk to another container, make sure the container is specifically designed to withstand freezing temperatures. Again, leave some room at the top for expansion.
And don’t forget to label the container.
It might seem unnecessary when you know exactly what you’re putting into the freezer, but labeling can be surprisingly helpful. Write the date you froze the milk on the container so you’ll know how long it has been stored.
This is especially useful if you’re someone whose freezer tends to become a collection of mystery containers.
Should You Freeze the Whole Jug or Make Milk Ice Cubes?
There are actually a couple of different ways you can freeze milk, depending on how you plan to use it.
The easiest method is to freeze the milk in the original plastic jug after making sure there’s enough room for expansion.
But what if you don’t need an entire gallon?
That’s where milk ice cubes can come in handy.
Instead of freezing the entire container, you can pour smaller amounts of milk into an ice cube tray and freeze them individually. Once the milk cubes are frozen, you can transfer them to a freezer-safe bag or container.
This method is particularly useful if you only occasionally need a small amount of milk.
For example, maybe you have a recipe that calls for half a cup of milk. Instead of opening a fresh container every time, you can grab the amount you need from your freezer.
Milk ice cubes can also be convenient for coffee, smoothies, sauces, soups, baking recipes, and other dishes where you only need a little milk at a time.
There’s something very satisfying about having small portions ready to go instead of wondering what you’re going to do with the rest of the container.
How Long Can Frozen Milk Last?
According to the tips shared in the original sources, frozen milk can be stored for up to about three months.
For the best quality, however, you’ll want to use it sooner rather than later.
Remember that freezing is primarily a way to preserve milk and prevent it from spoiling as quickly. It doesn’t necessarily mean the milk will taste exactly the same after thawing.
When milk freezes and thaws, its texture can change somewhat. You may notice that it looks a little separated or different from fresh milk.
Don’t panic.
That doesn’t necessarily mean it has gone bad.
A good shake or stir can help bring it back together. If you’re particularly sensitive to changes in texture, you may prefer to use previously frozen milk in cooking and baking rather than drinking it straight from a glass.
That’s one of the reasons milk cubes are so useful. They can be added directly to recipes where any slight texture change is much less noticeable.
How to Thaw Frozen Milk
Once you’re ready to use your frozen milk, you’ll need to thaw it properly.
The easiest method is to move the frozen milk from the freezer to the refrigerator and let it thaw slowly.
Depending on the amount of milk you froze, this can take roughly 24 hours.
I know—waiting a whole day can feel like forever when you suddenly realize you need milk for pancakes.
But if you have time to plan ahead, refrigerator thawing is the simplest approach.
If you need the milk more quickly, you can also place the container in a sink or bowl filled with cold water. The original tips suggest that milk can thaw in around 30 minutes using this method, although the exact amount of time will depend on how much milk you’re thawing and how frozen it is.
You’ll want to avoid using hot water to speed up the process. When it comes to perishable foods like milk, it’s better to thaw them safely rather than trying to rush the process with heat.
Once your milk has thawed, give it a good shake or stir before using it.
And, just like fresh milk, pay attention to its smell, appearance, and overall condition. If something seems off, it’s better not to use it.
What Can You Use Thawed Milk For?
This is where freezing milk becomes particularly useful.
You don’t necessarily have to drink thawed milk by the glass.
In fact, if the texture has changed slightly after freezing, using it in recipes may be your favorite way to use it.
Think about all the recipes that call for milk.
You can use thawed milk in:
-
Pancakes and waffles
-
Muffins
-
Cakes and cupcakes
-
Homemade bread
-
Mashed potatoes
-
Creamy soups
-
Sauces and gravies
-
Macaroni and cheese
-
Casseroles
-
Scrambled eggs
-
Smoothies
-
Oatmeal
-
Pudding and other desserts
You can also use small frozen portions in coffee or other drinks if the texture is acceptable to you.
Basically, if you have milk that you know you’re not going to finish before it spoils, freezing it gives you another option besides throwing it away.
No More Wasted Milk!
And that’s it!
I had no clue you could freeze milk, but now that I know, I’m definitely going to start doing it to avoid wasting so much.
It’s such a simple trick, and honestly, I’m wondering why I didn’t think of it sooner.
Think about how many times you’ve opened the refrigerator and realized you have milk that needs to be used immediately.
Maybe you bought a gallon because it was on sale. Maybe your kids suddenly decided they don’t like cereal anymore. Maybe you were out of town for a few days. Or maybe you simply overestimated how much milk your household would drink that week.
Instead of watching the expiration date get closer and closer, you can put some of that milk in the freezer.
That could mean fewer trips to the grocery store, less food waste, and potentially a little more money left in your wallet.
And if you have a large family, the savings could add up over time.
Stock Up When Milk Is on Sale
One of the biggest advantages of freezing milk is that it gives you a little more flexibility when grocery shopping.
If your favorite kind of milk goes on sale, you may be able to buy an extra container and freeze it for later rather than worrying about whether you’ll use it before the expiration date.
Of course, you still need enough freezer space to store it, and you should always check the container and follow appropriate food-safety practices.
But for households that go through milk regularly, having an extra container tucked away can be convenient.
It can also be helpful during particularly busy weeks when you don’t want to make another trip to the store.
Going on Vacation? Freeze It!
Here’s another situation where this trick could come in handy.
Let’s say you’re leaving for vacation and you have half a gallon of milk sitting in the refrigerator.
You know you won’t be home to use it, and by the time you return, it may be past its prime.
Rather than letting it sit there and eventually end up down the drain, you can freeze it before you leave.
When you get back, move it to the refrigerator to thaw.
Of course, if you’ll be gone for a long time, you may prefer to simply use or give away the milk before leaving. But for shorter trips, freezing can be a convenient option.
Small Portions Can Make Life Easier
I think the milk ice cube idea might actually be one of my favorite parts of this whole trick.
Sometimes you don’t need a whole cup of milk.
Maybe you need a splash for coffee. Maybe a recipe calls for a small amount. Maybe you want to add some milk to a smoothie.
Having frozen portions available means you don’t have to worry about opening an entire container just for a little bit.
You can also freeze different amounts depending on how you typically cook.
If you regularly make recipes that call for a cup of milk, you could freeze that amount separately. If you use milk mostly in small amounts, smaller portions may make more sense.
It’s basically a way to turn your freezer into a backup supply of milk.
A Few Things to Remember
While freezing milk is simple, there are a few things worth keeping in mind.
First, leave room for expansion. This is probably the most important step. Don’t fill a container all the way to the top.
Second, use freezer-safe containers if you’re transferring the milk. Avoid freezing milk in glass containers that aren’t designed for freezing.
Third, label your milk with the date. That way, you’ll know which container should be used first.
Fourth, thaw it safely. The refrigerator is the easiest option if you have time. Cold water can help when you need it sooner.
Finally, expect some changes in texture. Frozen and thawed milk may separate or look slightly different. Give it a good shake or stir, and consider using it in cooking and baking if you don’t enjoy the texture for drinking.
No More Last-Minute Grocery Store Runs
One of my favorite things about simple kitchen tricks like this is that they can solve a surprisingly annoying everyday problem.
Running out of milk when you need it is frustrating.
So is opening the refrigerator and realizing that the milk you bought several days ago is about to expire.
Freezing milk gives you another option.
Instead of thinking, “We’re never going to use all of this,” you can think, “I’ll save some for later.”
Instead of making an emergency grocery store run because everyone suddenly wants cereal, you can check the freezer.
And instead of feeling guilty about pouring perfectly usable milk down the drain because you bought more than your family needed that week, you can preserve it for another time.
It’s not a complicated kitchen hack. It doesn’t require any special equipment. And once you get into the habit of doing it, it could become one of those little tricks you wonder how you ever lived without.
So if your household is as unpredictable with milk as mine is, this might just be the solution.
Now I just need to figure out how to predict our cereal consumption.
And our yogurt consumption.
And our banana consumption.
Actually, maybe I’ll just start freezing everything.
The struggle never ends!
