What temperature should water be for poaching eggs?
Water at 180-190°F (82-88°C) — barely simmering, NEVER boiling. Surface should show small bubbles rising occasionally but not a rolling boil. At rolling boil (212°F / 100°C), egg whites disperse into strings. At simmer, whites coagulate cleanly around yolk in 3-4 minutes.
The full answer
The poaching temperature window
Egg whites coagulate (set into gel) between 144°F (62°C) and 158°F (70°C). Egg yolks set fully at 158°F (70°C) and over. To poach properly, the water needs to be hot enough to cook the egg in 3-4 minutes but not so hot that it tears the white apart. The sweet spot: 180-190°F (82-88°C) — barely simmering with intermittent small bubbles.
Visual identification of correct temperature
- 180-190°F (82-88°C): small bubbles rise occasionally to surface; water is moving but not turbulent. Steam visible but gentle.
- At 212°F (100°C) full boil: rolling bubbles everywhere; water turbulent. EGGS WILL DISPERSE.
- Below 170°F (76°C): water barely moving; egg whites won't fully coagulate; risk of bacterial growth + slimy texture.
The classic French method (the canonical published technique)
- Fill saucepan with water 3 inches deep. Use wide pan (more surface area = easier egg control).
- Add 1 Tablespoon white vinegar per liter of water (helps egg whites coagulate faster).
- Heat to 180-190°F (82-88°C) — bubbles visible but not rolling.
- Crack each egg into a small ramekin or measuring cup first (gives you control).
- Use spoon to swirl water gently in one direction.
- Slip egg into the swirl center.
- Cook 3-4 minutes (longer = harder yolk).
- Lift out with slotted spoon; drain on paper towel.
Why vinegar in the water
Acetic acid (vinegar) lowers the protein-coagulation temperature, helping egg whites set faster + tighter. Use white vinegar (neutral flavor); 1 Tablespoon per liter. Lemon juice works but adds noticeable flavor.
Cooking times
| Result | Time at 185°F |
|---|---|
| Soft (runny yolk, just-set white) | 2-3 minutes |
| Medium-soft (slightly thick yolk) | 3-4 minutes (most common) |
| Medium (thick yolk) | 4-5 minutes |
| Hard yolk | 5-6 minutes |
| Over-poached (rubbery) | 6+ minutes |
Common mistakes
- Boiling water: turbulent water tears egg whites; produces stringy mess. Lower heat to gentle simmer.
- Cold/old eggs: older egg whites are looser, disperse more. Fresh eggs (< 1 week) poach cleaner.
- Cracking egg directly into water: loses control; egg disperses immediately. Always use intermediate vessel.
- Skipping vinegar: whites take 1-2 extra minutes to set + spread more.
- Overcrowding pan: poach one or two eggs at a time. More = uneven cook.
Pre-poaching for service (batch method)
For brunch/restaurant service, poach eggs ahead: 1. Poach as above, but only 2 minutes (under-done) 2. Immediately transfer to ice water 3. Refrigerate up to 24 hours 4. To serve: drop into 180°F water for 60 seconds to reheat + finish cook
Egg holder method (for crisper edges)
Place egg in a fine-mesh strainer over a bowl first. Looser/older egg whites drain through the strainer (the discarded portion would have made strings in the water anyway). What stays in the strainer is the firmer, fresher white that poaches cleanly.

Time ranges by condition
| Condition | Duration | Note |
|---|---|---|
| Optimal poaching water | 180-190°F (82-88°C), barely simmering | — |
| Soft poach (runny yolk) | 2-3 minutes | — |
| Medium poach (thick yolk) | 3-4 minutes | most common |
| Hard poach | 5-6 minutes | — |
| NEVER (rolling boil) | 212°F (100°C) | disperses egg whites |
What changes the time
- Water temperature. Below 170°F: whites won't coagulate. Above 200°F: turbulence tears whites. Sweet spot: 180-190°F.
- Egg freshness. Fresh eggs (< 1 week): tighter whites, poach cleanly. Old eggs (3+ weeks): looser whites, disperse more.
- Vinegar in water. 1 Tbsp white vinegar per liter accelerates white coagulation; reduces stringing by 50%
- Pan size. Wider pan: easier egg control + better surface area. Smaller pan: water cools faster as eggs added.
- Altitude. Above 3000ft: water boils at lower temp; reduce target by 5-10°F; cooking time may need +30 seconds
Common questions
Why does my poached egg fall apart in the water?
Three most-likely causes: (1) Water is too hot — rolling boil disperses egg whites. Lower to 180-190°F (small bubbles only). (2) Eggs are old — old egg whites are looser and disperse more readily. Use eggs less than 1 week old when possible. (3) Cracking egg directly into water without an intermediate vessel — always crack into a small ramekin or measuring cup first, then slide gently into water. Adding 1 Tablespoon white vinegar per liter helps whites coagulate faster.
Can I poach multiple eggs at once?
Yes, but maximum 4 eggs per saucepan and only if pan is wide enough. More eggs cool water below 180°F + create crowded surface where whites tangle. For 6+ eggs, use a wide skillet (12-inch). Crack all eggs into separate ramekins first. Lower each one in succession (1 second apart) into the simmering water. Some chefs prefer poaching individually for restaurant-quality results.
Can I poach an egg without vinegar?
Yes, but eggs will spread slightly more and take 1-2 minutes longer to fully set. Vinegar isn't essential — it just speeds and tightens coagulation. For vinegar-free poaching: use very fresh eggs (under 1 week old), simmer water at 180°F precisely, swirl water gently in one direction before adding egg, and cook 4-5 minutes. The mesh-strainer trick (drain off the loose whites first) is the best vinegar-free way to get clean edges.
