What You Can Freeze and What You Can't
Freezing food is the easiest way to make sure nothing goes to waste.
When you bring food home from the pantry, some of it needs to be used quickly and some of it can sit on a shelf for months. But there's a third option people often forget about: the freezer. Freezing food buys you weeks or months of extra time and prevents the most common source of waste, which is fresh items going bad before you get to them.
Here's what freezes well, what doesn't, and how to do it right.
Freezes great
Ground beef, chicken, and pork
Raw meat freezes perfectly and lasts 3-4 months in the freezer. If it comes in a large pack, divide it into meal-sized portions before freezing so you can thaw only what you need. Wrap tightly in plastic wrap or put it in a zip-lock bag with as much air squeezed out as possible.
Bread
Bread freezes and thaws beautifully. Put the whole loaf in the freezer and pull out slices as you need them. Individual slices thaw in minutes at room temperature or can go straight into the toaster. Tortillas freeze well too. Separate them with small pieces of wax paper or parchment so they don't stick together.
Butter
Butter lasts 6+ months in the freezer with no change in quality. If you get extra sticks from the pantry, freeze them. Just move one to the fridge the night before you need it.
Cheese
Block and shredded cheese freeze well. The texture changes slightly after thawing (it can get a bit crumbly), so it's best for cooking rather than eating plain. Shredded cheese actually freezes better than block because it thaws more evenly. It works perfectly in quesadillas, mac and cheese, and casseroles straight from the freezer.
Cooked rice
Cook a big batch, let it cool, and freeze it in portion-sized containers or bags. Reheat in the microwave with a splash of water. This is a huge time saver for weeknight meals and makes fried rice even easier since day-old rice is ideal for frying.
Cooked beans
If you cooked a big pot of dried beans, freeze the extras in 1-2 cup portions. They thaw quickly and work just like canned beans in any recipe.
Bananas
When bananas start getting brown, peel them and put them in the freezer. Frozen bananas are perfect for oatmeal (just microwave and mash) or smoothies if you have a blender. They won't look pretty after thawing but they taste fine.
Fresh vegetables (with blanching)
Most fresh vegetables freeze well if you blanch them first. Blanching means boiling them for 1-2 minutes, then immediately putting them in cold water to stop the cooking. This preserves color, texture, and nutrition. Then drain, pat dry, and freeze in bags. Broccoli, green beans, carrots, corn, and peas all work this way.
Freezes okay (with caveats)
Milk
You can freeze milk, but it separates when it thaws. Shake it well after thawing and it's fine for cooking, cereal, and baking. It might taste slightly different if you drink it straight. Leave some room in the container because milk expands when frozen.
Eggs
You can't freeze eggs in the shell (they'll crack). But you can crack them into a container, stir gently, and freeze. They work fine for cooking after thawing. You can also freeze egg whites and yolks separately.
Cooked pasta
Slightly undercook it before freezing so it doesn't turn to mush when reheated. Toss with a little oil so the noodles don't stick together. It's not as good as fresh, but it works for quick meals.
Don't freeze
Potatoes (raw)
Raw potatoes turn grainy and watery after freezing. Cooked potatoes (mashed, baked, or in a soup) freeze fine, but raw ones don't.
Lettuce and leafy greens (for eating raw)
Lettuce turns to mush when frozen. If you want to freeze spinach or kale, plan to cook it after thawing. Frozen spinach works great in eggs, pasta, and soups, but not in salads.
Mayo-based salads
Tuna salad, chicken salad, and anything with mayo separates and gets watery after freezing. Make these fresh and eat within a few days.
Canned goods (in the can)
Don't put cans in the freezer. They can expand and burst. If you want to freeze the contents, open the can and transfer to a freezer-safe container first.
General freezer tips
Label everything. Write what it is and the date on the bag or container. In two months you won't remember what that frozen lump is.
Squeeze out air. Air causes freezer burn. Press as much air out of bags as possible before sealing.
Freeze flat. Lay bags flat in the freezer so they stack neatly and thaw faster.
Thaw in the fridge. Move frozen items to the fridge the night before you need them. Don't thaw meat on the counter. If you forgot to plan ahead, use the defrost setting on your microwave or put the sealed bag in a bowl of cold water.
Use within 3-4 months. Frozen food is safe indefinitely, but quality starts to decline after a few months. Earlier is better.
The freezer is the most underused tool in a tight-budget kitchen. Almost anything you can't eat this week can be saved for next week. Use it and nothing goes to waste.
