How to Use This Tool
Enter the number of eggs you're cooking, select their size, and specify whether they're starting from the fridge or room temperature.
Choose your desired doneness level and add your altitude if you're cooking at high elevation.
Click "Calculate Time" to get precise cooking instructions, or use "Reset" to clear all fields.
Formula and Logic
The calculator uses a base time adjusted for egg size, starting temperature, and altitude:
- Base times: Soft (4 min), Medium (7 min), Hard (10 min)
- Size adjustment: Small (-1 min), Medium (0), Large (+1 min), Extra Large (+2 min)
- Temperature adjustment: Room temperature eggs cook 1 minute faster
- Altitude adjustment: Add 1 minute for every 300 meters above 1000m elevation
Times are calculated per egg; multiple eggs may require slight additional time in practice.
Practical Notes
- For best results, use a timer and a pot large enough to cover eggs with water.
- Immediately transfer cooked eggs to an ice bath to stop cooking and ease peeling.
- At high altitudes, water boils at lower temperatures, requiring longer cooking times.
- Room temperature eggs cook faster but may crack more easily; handle gently.
- Hard-boiled eggs are easier to peel when older (7-10 days in fridge).

Frequently Asked Questions
Can I cook eggs directly from the freezer?
It's not recommended; frozen eggs may crack during cooking. Thaw overnight in the fridge first.
How do I know if an egg is fresh?
Fresh eggs sink in water; older eggs stand upright or float. For boiling, slightly older eggs peel easier.
What if I don't have a timer?
Use your phone's stopwatch or a kitchen timer. Consistency is key for perfect doneness.
Additional Guidance
For soft-boiled eggs with runny yolks, serve immediately in egg cups or over toast.
Hard-boiled eggs can be stored in the fridge for up to one week; keep them unpeeled until use.
Experiment with seasoning blends or marinades for variety in your meal prep routine.
