How to Tell if Eggs Are Still Good
The date on the carton isn’t the full story. Here are three quick tests that actually tell you what’s going on inside the shell.
Cracked open an egg and hesitated for a second before using it? Most people have. The good news: telling if an egg is still good doesn’t require guessing — there are a few quick, reliable ways to check before it ever touches the pan. 🥚
Knowing how to tell if eggs are still good comes down to three simple checks, each one taking less than 30 seconds. None of them require special equipment, just a bowl of water and your own senses.
Three Tests, Fastest to Most Accurate
The Float Test
Drop the egg into a bowl of cold water. As an egg ages, it loses moisture through the shell and the air pocket inside grows — that air pocket is what makes an old egg float.
Sinks flat = fresh · Stands upright = use soon · Floats = toss itThe Sniff Test
Crack the egg into a separate bowl (not directly into whatever you’re cooking) and smell it. A bad egg has an unmistakable sulfur smell — there’s no confusing it with a fresh one. If it smells like nothing unusual, it’s fine.
The Visual Check
Once cracked, look at the white and yolk. Fresh eggs have a thick, cloudy-ish white that holds its shape and a firm, rounded yolk. Watery whites and flat yolks are signs of age — not necessarily unsafe yet, but past their best for frying or poaching.
What the Date on the Carton Actually Means
How Long Eggs Actually Last
| Storage | Typical Timeframe |
|---|---|
| Raw, in the fridge | 3-5 weeks past the pack date |
| Raw, at room temperature | Use within a few hours — don’t leave out |
| Hard-boiled, in the fridge | About 1 week |
| Raw, cracked in a sealed container | 2-4 days |
The single biggest factor isn’t the date on the carton — it’s whether the egg has stayed consistently cold. Eggs that go through temperature swings (left out, then refrigerated, repeatedly) age faster than the timeline above suggests. The FoodSafety.gov egg storage guidance is a good reference if you want the official federal recommendations alongside these quick tests.
How to Tell if Eggs Are Still Good: When in Doubt, Throw It Out
If an egg fails more than one test — floats and smells off, for example — don’t try to salvage it by cooking it thoroughly. Heat doesn’t reliably destroy every risk in a genuinely spoiled egg, and the tests above are quick enough that there’s rarely a good reason to take the chance. When in doubt, it genuinely isn’t worth the risk over the cost of a single egg.
Cooking a Lot of Eggs Lately?
If eggs are becoming a weekly staple, it might be worth finding out whether an egg cooker actually earns its counter space — or if a pot of water still does the job just fine.
