Sous vide cooking has revolutionized home and professional kitchens by offering precision, consistency, and unmatched control over food preparation. One of the most popular dishes to master using this technique is the soft boiled egg. Known for its silky yolk and custardy texture, a perfect sous vide soft boiled egg requires precise temperature control—and knowing the right temperature is key.
Among the many egg preparations, soft-boiled eggs remain a favorite for their delicate texture and versatility. Whether served on toast, paired with soldiers, or used as a topping for ramen, the soured sous vide soft boiled egg elevates the breakfast and brunch experience. But to achieve that perfect balance between a barely set white and a rich, runny yolk, the water bath temperature must be carefully managed.
This guide will explore how to sous vide soft boiled eggs, answering the critical question: What temperature do you sous vide soft boiled eggs? We’ll delve into the science behind sous vide cooking, the ideal temperatures for different styles, cooking times, prep techniques, and troubleshooting tips for consistent results.
Understanding Sous Vide Cooking: How It Works
Sous vide, which means “under vacuum” in French, involves sealing food in an airtight bag and cooking it in a precisely controlled water bath. The immersion circulator regulates the water temperature to within a fraction of a degree, ensuring that food cooks evenly and retains moisture.
The Benefits of Sous Vide for Eggs
Eggs are particularly well-suited for sous vide cooking due to their composition of proteins and water. Traditional boiling methods often lead to overcooking, rubbery textures, or inconsistent doneness. Sous vide allows egg proteins to coagulate at known temperature thresholds, providing precise control over the final texture.
Here’s a quick breakdown of protein coagulation in eggs:
- Egg whites begin setting at around 63°C (145°F)
- Egg yolks start to coagulate at about 65–70°C (149–158°F)
The subtle variance in temperature allows chefs to manipulate the texture of both the white and yolk independently, making sous vide ideal for customizing egg dishes like soft boiled, medium boiled, or even custardy sous vide eggs.
Why Temperature Precision Matters
When sous vide cooking soft boiled eggs, even a few degrees can change the texture dramatically. That’s why choosing the right temperature is crucial. While 62°C to 67°C (144°F to 153°F) is the general range used for soft boiled eggs, the specific temperature depends on the desired yolk runniness and white setting.
Next, we’ll explore the best sous vide temperature for achieving that perfect soft boiled egg.
What Temperature Do You Sous Vide Soft Boiled Eggs?
The ideal sous vide temperature for soft boiled eggs typically falls between 62°C to 67°C (144°F to 153°F). However, subtle adjustments within this range yield distinct textures.
Soft Boiled Egg Temperature Guide
Let’s break down what different temperatures within the sous vide range produce:
| Temperature (°C) | Temperature (°F) | White Texture | Yolk Texture | Recommended Use |
|---|---|---|---|---|
| 62°C | 144°F | Slightly set | Very runny | Softest option, akin to egg drop soup texture |
| 63.5°C | 146°F | Softly set | Barely set yolk | Classic soft boiled texture |
| 65°C | 149°F | Set | Firmly runny yolk | Balance between soft and semi-firm yolk |
| 67°C | 153°F | Fully set | Partially set yolk | Medium boil, slightly less runny yolk |
Temperature Preferences: Finding What Works for You
The temperature choice ultimately depends on personal preference. Some diners enjoy a yolk that flows like liquid gold, while others prefer a slightly looser texture that doesn’t run too freely. Most commonly, 63.5°C (146°F) is widely accepted as the goldilocks zone for sous vide soft boiled eggs—producing whites that are tenderly set and yolks that are silkily soft.
How Long to Sous Vide Soft Boiled Eggs
While temperature is the primary variable for yolk and white consistency, cooking time also plays a role. Even though eggs cook slowly in a sous vide bath, they don’t need excessive time.
Typical Sous Vide Soft Boiled Egg Time
For soft boiled eggs, a sous vide time of 45 minutes to 1 hour is sufficient. This range ensures that the eggs are fully heated without becoming overcooked.
However:
- 45 minutes: Slightly less consistent results, especially with larger eggs.
- 60 minutes: Better coagulation and uniform heat distribution. Ideal for soft boil.
- 75–90 minutes: Yolks may firm slightly, leading to a texture closer to medium boil.
Can You Overcook Sous Vide Eggs?
Since sous vide cooking is precisely temperature-controlled, you can’t technically “overcook” the eggs in the way you might with boiling or frying. Still, if left in the water bath too long, even at the right temperature, the yolks can develop a firmer, more custardy texture.
As a general rule:
– For soft-boiled perfection: 45–60 minutes at 63.5°C (146°F)
– For short holding (e.g., preparing breakfast in batches): Up to 90 minutes is okay
– Longer than 90 minutes: Texture may start shifting toward custard-like or “jammy”
Step-by-Step Guide to Sous Vide Soft Boiled Eggs
Now that you know the right temperature for sous vide soft boiled eggs, here’s how to prepare them.
Step 1: Gather Supplies and Ingredients
Before starting, make sure you have the following:
- Sous vide immersion circulator
- Large container or sous vide water bath
- Heat-safe bags (ziplock or vacuum-seal compatible)
- Fresh large eggs
- Water
- A bowl of ice water for finishing
Step 2: Preheat the Sous Vide Water Bath
Set your sous vide cooker to 63.5°C (146°F). Fill your container with water up to the indicated line. Allow the water to heat fully before proceeding. Never place eggs in unless the temperature is accurate.
Step 3: Prepare the Eggs
There are two ways to sous vide eggs:
- Leave them in the shell
- Crack and sieve the eggs for perfect shape
Most prefer to cook them in the shell for soft boiled purposes, as it’s easier. Gently place the eggs into a ziplock bag or vacuum-seal bag. Adding a small amount of water to the bag helps in submerging the eggs and prevents floating.
Tip: Adding herbs or butter to the bag can infuse the eggs for gourmet variations.
Step 4: Sous Vide Cook the Eggs
Submerge the bagged eggs in the water bath. Make sure they are fully submerged—use a clip or weight if necessary. Cook for 1 hour at 63.5°C (146°F) for best results.
Step 5: Finish and Serve
After cooking, transfer the eggs to an ice bath for 1–2 minutes. This prevents carryover cooking and makes them easier to peel if desired.
Serve immediately:
- In an egg cup with toast soldiers
- Over avocado toast
- Cracked into ramen or shakshuka
Troubleshooting Soft Boiled Sous Vide Eggs
Despite its precision, sous vide egg cookery can sometimes surprise users. Here’s what to look for when the results don’t meet expectations:
Problem: Yolk Too Runny
If your sous vide egg yolk is excessively liquid, it likely reflects a very low temperature or a shorter cooking time. Try:
– Increasing the temperature slightly to 64°C (147°F)
– Extending cooking time to 60 minutes
Problem: Yolk Too Firm
On the flip side, if the yolk has firmed up more than desired, you’re either cooking too long or at a temperature that’s on the higher end of the spectrum. Adjust by:
– Reducing time to 45 minutes
– Lowering the temperature to 63°C (145°F)
Problem: Egg White Not Fully Set
If the egg white is too soft or even runny, it could indicate:
– Temperature too low (below 63°C)
– Cooking time too short
Solution:
– Increase temperature to 63.5°C (146°F)
– Maintain cooking time at 1 hour
Problem: Water Bath Evaporation
One common issue in longer sous vide sessions is evaporation. To mitigate this:
– Use a water bath lid or aluminum foil
– Check water levels halfway through cooking
Advanced Sous Vide Egg Techniques
Once you’ve mastered the soft boiled sous vide egg basics, you can experiment with variations for special dishes or fine dining presentation.
Sous Vide Eggs with Infusions
Enhance flavor by adding herbs like chives, thyme, or butter just before sealing the bag. This works best with peeled, cracked eggs or shelled eggs with a puncture in the air cell.
Custom Plating and Presentation
Serve sous vide soft eggs on:
– Toasted sourdough with caviar
– Poached brioche with dill crème fraîche
– On top of a warm salad or ramen
Difference Between Coddled and Sous Vide Eggs
While coddled eggs are cooked in a water bath in a special container that allows for gentle cooking, sous vide provides superior temperature control. Sous vide eggs offer consistency every time, while coddling can lead to inconsistency depending on the container and stove heat.
Why Sous Vide Is the Best Method for Soft Boiled Eggs
Compared to traditional boiling, microwave soft-boiled methods, or other kitchen hacks, sous vide offers several advantages:
Consistency and Reproducibility
Every batch, every time, will yield the same texture. No need to guess or time your stovetop boil.
Control Over Texture
Sous vide allows for full manipulation of white and yolk consistency by adjusting temperature and time. This makes it ideal for customizing for children, guests, or personal preference.
Less Waste and Greater Yield
The eggs are cooked in the shell and rarely crack, resulting in minimal waste and a 100% edible product in most cases.
Great for Meal Prep
Cook multiple eggs at once and keep them chilled for up to 3–4 days, reheating in warm water before serving.

What is the ideal temperature for sous vide soft boiled eggs?
The ideal temperature for sous vide soft boiled eggs typically ranges between 165°F (74°C) and 172°F (78°C). This range allows for precise control over the doneness of both the white and the yolk. At the lower end of the spectrum, the whites will be just set, while the yolk remains very runny. Increasing the temperature slightly firms up the white and begins to thicken the yolk, offering a balance preferred by many soft-boiled egg enthusiasts.
Cooking time also plays a role in the final texture, but with sous vide, the temperature control ensures consistent results. For a classic soft-boiled egg with a slightly thicker white and a creamy yolk, a common recommendation is 167°F (75°C) for 45 minutes. This temperature and time combo creates a silky texture that’s hard to achieve with traditional boiling methods, making it a favorite among home cooks and chefs alike.
How long should I sous vide soft boiled eggs?
Cooking time for sous vide soft boiled eggs generally ranges from 45 minutes to 1 hour when cooked at temperatures between 165°F (74°C) and 172°F (78°C). This duration ensures that the eggs are evenly heated and the proteins have coagulated to the desired consistency without overcooking. A typical time of 45 minutes at 167°F (75°C) yields a custard-like yolk with whites that are tender but fully set.
While sous vide eggs can be left in the water bath for longer periods—up to 2 or 3 hours—they will not become rubbery like boiled eggs. However, cooking beyond an hour may begin to thicken the yolk more than desired for a classic soft-boiled texture. For best results, stick closely to the 45-minute to 1-hour window if serving immediately or cool and refrigerate for later use.
Can I sous vide multiple eggs at once?
Yes, you can sous vide multiple eggs at once, as long as your sous vide container is large enough to accommodate them without overcrowding. Since eggs cook evenly when fully submerged and at a consistent temperature, the quantity has little impact on cooking time or outcome. You can cook anywhere from one egg to a dozen without needing to adjust the temperature or cooking duration.
Just ensure each egg has enough space for water to circulate freely around it. If stacking is necessary, place a rack or mesh basket at the bottom to prevent direct contact with the heater or base of the container. Cooking multiple eggs is efficient and ideal for meal prep, brunches, or breakfast for a group. After cooking, you can hold the eggs in warm water for up to an hour or chill them and reheat later in hot water.
Do I need to peel sous vide eggs immediately?
You do not need to peel sous vide eggs immediately after cooking unless you’re serving them right away. In fact, leaving the eggs in their shells helps maintain freshness and makes them easier to handle if you plan to store or reheat them. Once you’re ready to eat, simply crack the shell gently and peel under cool running water for easier removal.
However, if you’ve cooked the eggs for meal prep and want to store them peeled, you can do so. Pooled sous vide eggs can be stored in airtight containers in the refrigerator for up to two days. Just be sure to submerge them in cold water or a light brine to prevent oxidation and drying. Peeling before storage is optional and depends primarily on how and when you plan to use them.
Can I sous vide soft boiled eggs in their shells?
Yes, you can sous vide soft boiled eggs directly in their shells, which is the most common and convenient method. Cooking eggs in the shell protects the delicate white and yolk, ensuring even heating and minimizing the risk of breakage or uneven textures. Simply place the eggs in a water bath at the desired temperature, usually between 165°F (74°C) and 172°F (78°C), and cook for 45 minutes to an hour.
The shells also help maintain the egg’s shape and structure, which is particularly beneficial when using them in dishes like ramen, salads, or toast toppings. This technique retains the natural moisture of the egg, resulting in a creamier texture compared to traditional boiling. When done, you can peel the eggs immediately or store them in the refrigerator for later use—either in the shell or peeled and refrigerated in water.
Can I reheat sous vide soft boiled eggs after refrigeration?
Yes, you can reheat sous vide soft boiled eggs after refrigeration, and they maintain their texture and flavor remarkably well. To reheat, simply place the eggs (still in their shells if not already peeled) into a water bath set at around 165°F (74°C) for about 15 to 20 minutes. This gentle reheating process ensures the egg returns to its original creamy consistency without overcooking.
Alternatively, if a sous vide machine is not available, you can reheat them in a bowl of hot water for a similar effect. Avoid using a microwave or stovetop method, as these can lead to uneven heating and potentially rubbery textures. Reheating is best suited for eggs that were chilled after sous vide cooking and stored properly, ideally peeled and submerged in water to prevent oxidation or drying.
What happens if I sous vide eggs at too high a temperature?
If you sous vide eggs at too high a temperature, especially above 175°F (80°C), you risk overcooking them, which results in rubbery whites and a chalky, fully set yolk. Unlike traditional boiling, where time can dramatically impact doneness, sous vide temperature alone is the main determinant of texture when cooking within a certain time window. Exceeding the optimal temperature range can permanently alter the egg’s delicate structure, leading to a less appealing result.
Additionally, cooking at temperatures higher than recommended does not significantly reduce cooking time but instead accelerates protein denaturation, making the final product drier and less palatable. It’s essential to follow the recommended temperature guidelines for soft-boiled eggs, which usually fall between 165°F (74°C) and 172°F (78°C), to maintain a tender white and a silky yolk. Staying within this narrow band ensures the creamy and custard-like texture that sous vide is celebrated for.
