How Long Do Eggs Last? The Direct Answer
Raw whole eggs in their shell last 3 to 5 weeks in the refrigerator from the purchase date, according to USDA guidelines confirmed by the American Egg Board. Hard-boiled eggs, by contrast, last only 1 week in the refrigerator whether they're peeled or still in the shell. Frozen eggs, when properly prepared, hold up for up to 1 year in the freezer without meaningful quality loss.
One thing that surprises a lot of shoppers: the sell-by or expiration date printed on the carton is not a safety cutoff. According to University of Illinois Extension, properly refrigerated eggs are often safe to eat 3 to 5 weeks beyond that date. What matters most is keeping your eggs at or below 40°F (4°C) for the full duration of their shelf life. Our guide on how long eggs are good in the refrigerator breaks down this timeline in more detail, and our refrigerator temperature settings for food safety guide explains exactly how to confirm your fridge is holding the right temperature.
Egg Shelf Life by Type, Storage Method, and Freshness Tests
Raw Eggs in the Shell
Raw whole eggs stored in the refrigerator last 3 to 5 weeks from the purchase date, even after the sell-by date passes. The American Egg Board and University of Illinois Extension both confirm this window. The key is consistent cold storage. Our article on what temperature a refrigerator should be at explains why even small temperature swings matter, and how refrigerator temperature impacts food nutrition shows that quality and nutrition decline together when storage conditions slip.
Separated Egg Yolks and Whites
Once you separate an egg, the clock speeds up. Raw yolks last only 2 to 4 days in the refrigerator. To prevent a dry skin from forming on the surface, cover them with a thin layer of cold water before sealing the container. Raw whites are slightly hardier, lasting up to 4 days refrigerated, and they freeze exceptionally well for up to 12 months, making them a great candidate for batch prep.
Hard-Boiled and Soft-Boiled Eggs
Hard-boiled eggs last up to 1 week in the refrigerator. If you've already peeled them, keep them submerged in cold water in a covered container and change the water daily. If you prefer using an Instant Pot for hard-boiled eggs, the same storage rules apply once they're cooked.
Soft-boiled eggs are more perishable. Because the yolk is only semi-set and not fully cooked through, they last just 2 days refrigerated. Don't count on stretching that window.
Pickled Eggs
Pickled eggs are a genuinely long-lasting option. Stored in a sealed, sterile jar with a proper vinegar brine and kept refrigerated, they last 3 to 4 months. They're a practical solution when you have an abundance of farm-fresh eggs and want to preserve them without freezing.
Frozen Eggs
You can freeze whole eggs, yolks, and whites, but never freeze them in the shell. The liquid expands as it freezes and cracks the shell, which creates a food safety risk. To freeze whole eggs safely, crack and beat them until blended, pour into a freezer-safe container or ice cube tray, label with the date and number of eggs, and freeze. All forms, whether whole beaten eggs, yolks, or whites, last up to 1 year at 0°F (−18°C).
One important tip for yolks: mix in half a teaspoon of salt or sugar per four yolks before freezing. Without it, the yolks become thick and gelatinous during freezing and won't blend smoothly into recipes after thawing. When you're ready to use frozen eggs, move the container to the refrigerator the night before and use within 24 hours of thawing. Never thaw eggs at room temperature.
Farm-Fresh vs. Store-Bought Eggs
This is where egg storage gets genuinely interesting. Farm-fresh eggs that haven't been washed retain a natural protective coating called the bloom or cuticle. That coating seals the porous shell against bacteria and prevents moisture loss, which is why unwashed farm-fresh eggs can safely sit at room temperature for up to 2 weeks, as Purina Mills notes in their egg freshness guide. In the refrigerator, they can last up to 3 months.
Store-bought eggs in the US are a different story. They're legally required to be washed and sanitized before sale, which strips the bloom entirely. From that point, refrigeration isn't optional; it's mandatory. And their practical shelf life drops to 3 to 5 weeks refrigerated, not months. Home cooks on homesteading forums have discussed this distinction at length, and the consensus holds: once washed, always refrigerated.
One mistake to avoid is washing farm-fresh eggs before storing them at home. Doing so removes the bloom and introduces moisture that can push bacteria through the porous shell. Leave unwashed eggs unwashed until right before you use them.
Pasteurized shell eggs, which you'll find in some specialty grocery sections, last the same 3 to 5 weeks refrigerated as standard shell eggs. Their advantage isn't longevity but safety; they're the right choice for recipes calling for raw or lightly cooked eggs, such as Caesar dressing or hollandaise.
Where You Store Eggs in the Fridge Matters
The back of a middle or lower shelf is the best spot for eggs. The refrigerator door might seem convenient, but it experiences the most temperature fluctuation of any part of the appliance every time you open it. That repeated cycling between cold and slightly warmer temperatures shortens egg life noticeably and can cause condensation to form on the shell, which may drive bacteria through the porous surface.
If your fridge is running too cold and actually freezing items near the back, check out our guide on what to do if your fridge is freezing food, because frozen eggs in the shell crack and can't be used safely.
Keep eggs in their original carton rather than transferring them to a built-in egg tray. The carton does three useful things: it blocks odors from other foods (eggs absorb smells readily through their porous shells), it retains moisture around the shell, and it shields the eggs from light. If you're curious about how other perishables compare, our guide on how long thawed turkey stays in the fridge is a useful reference for thinking about refrigerated food safety more broadly.
Reading the Julian Date on Your Egg Carton
That three-digit number printed on most egg cartons is a Julian date, ranging from 001 (January 1) to 365 (December 31). It tells you the day of the year the eggs were packed, not when the hens laid them. Eggs packed on February 15, for example, carry the code 046. Knowing this helps you calculate the actual age of your eggs when no clear expiration date is visible.
How to Tell if an Egg Has Gone Bad
Three quick checks will tell you everything you need to know.
The float test. Fill a bowl with cold water and submerge the uncracked egg. A fresh egg sinks and lies flat on its side. A slightly older but still good egg sinks but stands upright. A bad egg floats to the surface. Floating happens because moisture evaporates through the porous shell over time, expanding the air cell inside. A floating egg goes in the trash, not the pan.
The smell test. Crack the egg into a bowl and smell it immediately. A bad egg has an unmistakable sulfur or rotten odor that's impossible to miss. If there's any off smell at all, discard it. This test is definitive.
Visual inspection. A fresh egg white is thick, gel-like, and stays close to the yolk. An old egg white is thin, watery, and spreads widely across the pan. More concerning, a pink, iridescent, or greenish tint to the white can indicate Pseudomonas bacteria contamination. That egg must be discarded immediately regardless of how it smelled.
Once you're confident your eggs are fresh, there's a whole range of cooking options available. Whether you're looking at various ways to cook eggs, need a fast weekday option like a microwave poached egg, or want to explore more methods via our food category, knowing your eggs are fresh makes every recipe more reliable.
Putting It All Together: Make Your Eggs Last Longer
The single most impactful step you can take is keeping your refrigerator at exactly 40°F (4°C) or below. That one setting determines whether your eggs reach their full 3 to 5 week potential or fall short of it. Our refrigerator temperature settings for food safety guide walks you through how to check and adjust your settings accurately. For appliance-specific recommendations, our refrigerators category covers a wide range of models and features worth knowing about.
Beyond temperature, always store eggs in their original carton on a middle or lower shelf, never in the door. Farm-fresh eggs with their bloom intact can sit at room temperature for up to 2 weeks, but once washed they need to go straight into the fridge. University of Illinois Extension reinforces this point clearly.
When you're unsure about a particular egg, the float test and a quick smell check after cracking take seconds and give you a confident answer. And understanding that sell-by dates aren't safety deadlines can meaningfully reduce the amount of perfectly good food you throw out each week.
Frequently Asked Questions About Egg Shelf Life
Q: How long do raw eggs last in the refrigerator?
Raw whole eggs in their shell last 3 to 5 weeks in the refrigerator when stored at or below 40°F (4°C). This timeline starts from the purchase date, not the lay date. The sell-by date on the carton may pass before those 5 weeks are up, but the eggs are still safe to eat as long as they pass the float test and smell normal after cracking. For a deeper look, see our guide on how long eggs are good in the refrigerator.
Q: How long do hard-boiled eggs last?
Hard-boiled eggs last up to 1 week in the refrigerator whether they're peeled or still in the shell. Peeled hard-boiled eggs should be kept submerged in cold water in a covered container with the water changed daily. Don't freeze hard-boiled eggs; the cooked whites become rubbery and watery when thawed, per the American Egg Board.
Q: Can you freeze eggs, and how long do they last in the freezer?
Yes, but never in the shell. Crack and beat whole eggs until blended, then freeze in a sealed freezer-safe container for up to 1 year. Egg whites alone freeze for up to 12 months. Mix yolks with a small amount of salt or sugar before freezing to prevent them from thickening. Thaw frozen eggs overnight in the refrigerator and use within 24 hours.
Q: How can you tell if an egg has gone bad?
Three methods work reliably. The float test identifies bad eggs before you even crack them. The smell test, performed immediately after cracking, picks up any sulfur or rotten odor. Visual inspection looks for thin, watery whites or a pink and iridescent tint, which signals bacterial contamination. Any one of those signs is reason enough to discard the egg, per Purina Mills.
Q: Do farm-fresh eggs last longer than store-bought eggs?
Unwashed farm-fresh eggs can last up to 2 weeks at room temperature or up to 3 months refrigerated because the bloom is intact. Store-bought eggs in the US are legally washed before sale, which removes the bloom and limits their refrigerated life to 3 to 5 weeks.
Q: Is it safe to store eggs on the refrigerator door?
No. Door shelves experience the most temperature swings of any spot in the fridge. Those fluctuations speed up deterioration and can push bacteria through the shell. Keep eggs on a middle or lower shelf toward the back, in their original carton.
Q: How long can eggs sit out at room temperature?
Store-bought eggs shouldn't sit out for more than 2 hours, or just 1 hour if the ambient temperature exceeds 90°F (32°C). Bacteria multiply rapidly in the danger zone between 40°F and 140°F (4°C and 60°C). Unwashed farm-fresh eggs with their bloom intact are safe at room temperature for up to 2 weeks, as confirmed by University of Illinois Extension.
Q: What about cooked egg dishes?
Cooked egg dishes like quiche or egg casserole last 3 to 4 days refrigerated in a covered container. Cracked raw eggs that can't be used immediately should be transferred to a clean sealed container and used within 2 days. You can't safely refreeze eggs that have already been thawed.
