Eggs: The Household Workhorse

What the numbers on the carton mean, how long eggs really keep, hard-cooked eggs that peel in seconds, cooking them through, freezing them, and the frittata that uses up the last six.

A carton of eggs is breakfast, lunch, a quick dinner, the binder in the meatloaf and the thing that saves a fridge full of odds and ends. It also comes with the most confusing dates in the kitchen and more myths than any other food. Here’s what the carton actually says, how long eggs really keep, the easiest hard-cooked eggs you’ll ever peel, and what to do with the half-dozen left when the week is almost over.

1 · The cartonWhat the numbers on the end mean.

A hand-drawn egg carton end stamped P1234, 277 and SELL BY NOV 03. The 277 is circled and explained as the pack date, day 277 of the year, October 4. A timeline then draws from packing to the latest a sell-by date (30 days) or a use-by date (45 days) can fall.
The three-digit number is the day the eggs were packed. The dates after it are about quality, not safety.

Look on the end of the carton for a three-digit number from 001 to 365: that’s the day of the year the eggs were washed, graded and packed (001 is January 1). A “sell by” date can be no more than 30 days after that, and a “use by” or “best before” date no more than 45 days, counting the pack day. Not every carton has one; it depends on your state. And none of them are a safety deadline: they’re about quality.

2 · Keeping themIn the carton, on a shelf. Not the door.

An open refrigerator with a closed cardboard egg carton on a middle glass shelf beside a bottle of milk and a covered butter dish, the door shelves holding only jars of jam, mustard and dressing.
The door is the warmest spot in the fridge. Eggs go on a shelf.
  • ✓

    In their carton — Keep them in the carton they came in, so the pack date stays with them.

  • ✓

    The coldest part of the fridge — At 40°F or colder. Not the door: it warms up every time you open it.

  • ✓

    3 to 5 weeks — Raw eggs in the shell keep 3 to 5 weeks in the fridge. For the best texture and flavor, aim for the first 3.

  • ✗

    Not on the counter — In the US, eggs are washed before they’re sold and need to stay cold. Once they’ve been refrigerated, don’t leave them out more than 2 hours.

3 · Hard-cooked eggsSteam them. They peel like a dream.

A steamer basket of white eggs in a saucepan on a gas burner, steam rising, the lid set aside, and a bowl of ice water with two eggs beside the stove.
An inch of boiling water, a steamer basket, 13 minutes.
  1. Step 1: Boil an inch of water

    Bring 1 inch of water to a rolling boil in a saucepan.

  2. Step 2: Steam · 13 min

    Put cold eggs straight from the fridge in a steamer basket, set it in the pan, cover, and turn the heat to medium. Cook 13 minutes. (No basket? Lower the eggs into the water with a spoon; it doesn’t matter if they’re partly under.) Works the same for 1 egg or 6.

  3. Step 3: Ice bath · 15 min

    Move the eggs into 2 cups of ice and 2 cups of cold water for 15 minutes.

  4. Step 4: Shake and peel

    Make the ice bath in a container with a lid. When the eggs are cold, pour off half the water, hold the lid on and shake hard, up and down, about 40 times, until the shells are cracked all over. They’ll slip right off.

Peeled or not, hard-cooked eggs keep a week in the fridge.

Hard-cooked eggs keep 1 week in the fridge, peeled or in the shell. Don’t freeze them.

4 · Cooking themSoft and creamy, and still cooked through.

Creamy scrambled eggs in big soft curds in a small nonstick skillet on a stove, a silicone spatula in the pan and chopped chives on a cutting board nearby.
Big, soft curds, cooked until there’s no runny egg left.

Scrambled eggs for 4: beat 8 eggs plus 2 extra yolks with ¼ cup half-and-half, a good pinch of salt and some pepper, just until it’s all one yellow. Melt 1 tablespoon butter in a 10-inch nonstick skillet over medium-high heat, pour in the eggs and keep scraping the bottom and sides with a spatula as big curds form, 1½ to 2½ minutes. Then turn the heat to low and fold gently until they’re set, another 30 to 60 seconds. No half-and-half? Use milk with a splash of cream.

5 · Use them upThe last six eggs are dinner.

A golden frittata with spinach, potato and ham in a nonstick skillet on a trivet, the cheese browned on top and one wedge cut out.
Six eggs and whatever’s left in the crisper.

Frittata for 4. Sauté 2 cups chopped vegetables (mushrooms, onions, peppers, tomatoes, or leftovers, thawed frozen or drained canned) in an ovenproof skillet over medium heat until tender, 3 to 5 minutes, then turn the heat to medium-low. Beat 6 eggs with ¼ cup milk and stir in ½ cup shredded cheese. Pour it over the vegetables, cover, and cook without stirring until nearly set, about 6 minutes. Slide it under a hot broiler for a minute or two to set and brown the top; it’s done at 160°F in the center. Leftover potatoes from No. 13 or tired herbs from No. 15 are perfect in it.

Egg fried rice. Leftover rice and a couple of eggs make one of the fastest dinners there is: scramble the eggs first and set them aside, stir-fry the rice and vegetables, then fold the eggs back in. More next-day ideas in No. 06.

Leftover egg dishes

Into the fridge within 2 hours, in shallow containers. Eat within 3 to 4 days and reheat to 165°F.

Leftover raw whites or yolks

Covered in the fridge for 2 to 4 days, or freeze them (below).

Baking without an egg

For one egg in a muffin or quick bread, 1 tablespoon ground flaxseed stirred into 3 tablespoons water often works; in boxed brownies, ¼ cup applesauce or Greek yogurt does. Swaps work best when the recipe calls for only one or two eggs. More in No. 07.

6 · Freezing eggsOut of the shell, they freeze for a year.

A glass bowl of lightly beaten eggs, a small silicone freezer tray with four portions of beaten egg, and a labeled zip-top freezer bag with a fork on an oak counter.
Three tablespoons of beaten egg equals one egg.
  1. Step 1: Never in the shell

    Eggs in the shell expand and crack in the freezer. Crack them first.

  2. Step 2: Whole eggs

    Mix the yolks and whites without whipping in air. For every cup, stir in ½ teaspoon salt (for savory cooking) or 1½ tablespoons sugar or corn syrup (for baking) so the yolks don’t go grainy. Freeze in a tray: 3 tablespoons = 1 egg.

  3. Step 3: Whites

    Nothing to add; just mix gently and freeze. 2 tablespoons = 1 white.

  4. Step 4: Yolks

    Add the same salt or sugar as for whole eggs. 1 tablespoon = 1 yolk.

  5. Step 5: Use them

    Label what you added. Frozen eggs keep up to a year. Thaw them in the fridge and use them within 3 to 5 days.
