For those who love their eggs runny but want to stay safe, using pasteurized eggs is a smart choice. This method works beautifully for single servings or small batches, making it ideal for weekend brunches or a luxurious weekday treat. Let’s get started on mastering the perfect 63°F egg.
Ingredients for 63 degree egg
Precision ingredients for temperature-controlled eggs that defy ordinary cooking expectations.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Eggs 🥚 | 4 whole | Freshly refrigerated, room temperature |
| Unsalted Butter 🧈 | 4 tbsp | European-style preferred for higher melt |
| Kosher Salt 🧂 | ½ tsp | Diamond Crystal preferred for delicate flavor |
| White Vinegar 🍶 | 1 tbsp | For gentle acidulation of whites |
| Cold Water 💧 | 1 cup | Ice bath preparation |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For frying surface |
| Pasteurized Eggs 🥚 | 4 whole | Optional safety alternative |
| Thermometer 🌡️ | 1 whole | Culinary-grade, 0-220°F range |
| Sourdough Bread 🍞 | 4 slices | Thick-cut, toasted |
| Avocado 🥑 | ½ whole | Ripe, sliced for garnish |
| Freshly Ground Black Pepper 🌶️ | ¼ tsp | Freshly cracked preferred |
| Fresh Chives 🌿 | 2 tbsp | Finely chopped for garnish |
The eggs are the foundation, so prioritize freshness and uniformity—look for eggs with tightly clustered yolks and firm whites. Pasteurized eggs eliminate any safety concerns while maintaining perfect texture. A thermometer is non-negotiable here; the Thermoworks Sous Chef or Meater Plus models provide reliable readings in this critical range. For butter, European-style (like Plugrá) has a higher smoke point and melts more cleanly. Store eggs in their original carton in the coldest part of your fridge—never the door—to maintain consistency. The vinegar is subtle but essential: it gently coagulates the whites at the precise moment without overcooking.
No thermometer? A deep-fry thermometer with a thin probe works in a pinch, but digital is ideal. Substitute white vinegar for lemon juice if needed, though it may impart a slightly different flavor profile. For butter, ghee can replace at a 1:1 ratio if you prefer a higher smoke point. The sourdough should be day-old for optimal toasting—fresh bread burns too quickly. Avocado substitution? Buttery cornichons add a similar richness without oxidation concerns. Fresh chives can be swapped for scallions, but they lack the delicate onion sweetness. When measuring water for the ice bath, chilled tap water works fine—boiling water would shock the eggs too aggressively.
Eggs should be used within 3 days of purchase for optimal texture. Store the thermometer in a dry, protected case when not in use—condensation can affect accuracy. Butter can be pre-softened by microwaving for 10 seconds (cover with a damp paper towel) to prevent splattering. The ice bath water should be pre-chilled in the fridge for 15 minutes before use. Leftover toasted sourdough? Wrap tightly in parchment paper and store at room temperature for up to 2 days. The avocado will oxidize quickly—squeeze lemon juice over slices and store in an airtight container with plastic wrap pressed directly against the fruit.

Step-by-step instructions for ultra-smooth 63°F eggs
Precision temperature control transforms ordinary eggs into velvety, heat-free perfection.
Prepare the Ice Bath for Temperature Control
Fill a deep bowl or container large enough to fully submerge the eggs with 1 cup of cold water and add 4 tablespoons of unsalted butter. Stir until the butter melts completely, creating a smooth emulsion. Place this mixture in the refrigerator to chill for 10 minutes—this ensures the final temperature stays precisely at 63°F. The butter’s fat content helps stabilize the egg whites while maintaining their delicate structure.
While the mixture chills, prepare an ice bath by filling a separate large bowl with fresh ice and water. This will be used to rapidly cool the eggs after cooking. The contrast between the warm eggs and icy bath is what creates that signature silky texture without any heat exposure. Keep the ice bath ready—you’ll need it immediately after removing the eggs from the stovetop.
Whisk Eggs and Vinegar for Stabilization
In a separate heatproof bowl, whisk together the 4 whole large eggs and 1 tablespoon of white vinegar until fully combined. The vinegar gently acidulates the whites, which helps them hold their shape better at the lower temperature. Avoid over-whisking—just enough to integrate the vinegar completely. This step is crucial for preventing any graininess in the final texture.
Place this egg mixture over a pot of simmering water (not boiling) to create a double boiler. The water should be at a gentle simmer—180°F—to maintain even heat transfer without cooking the eggs. Use the thermometer to monitor the water temperature constantly. If the water boils, the eggs will cook unevenly and may develop a slightly cooked flavor. Keep the heat at medium-low to maintain this precise temperature.
Cook Eggs to Exact Temperature
Submerge the bowl containing the egg mixture into the simmering water bath. Stir gently and continuously with a silicone spatula, ensuring the eggs heat evenly without forming a skin on the surface. Cook for 4-5 minutes, checking the temperature every 30 seconds with the thermometer. The eggs are perfect when they reach 63°F—this is the critical threshold where the whites become silky but remain completely raw.
Here’s the thing—if you exceed 63°F, even by a degree, you’ll start to develop a slightly cooked texture. I’ve learned this the hard way, so don’t rush. The moment the thermometer hits 63°F, remove the bowl from the heat immediately. The residual heat will carry it slightly higher, but the ice bath will correct this instantly.
Rapid Cooling in Butter Emulsion
Quickly pour the 63°F eggs into the pre-chilled butter mixture you prepared earlier. Stir vigorously for 30 seconds to distribute the butter evenly throughout the eggs. The butter’s fat content coats the egg proteins, preventing them from tightening up as they cool. This is what gives these eggs their signature ultra-smooth, almost custard-like texture.
Immediately transfer the bowl to the ice bath and let the eggs cool for 2 minutes. The ice bath shocks the proteins into their final silky state. You’ll notice the mixture thickens slightly as it cools—this is normal and desirable. Once fully chilled, the eggs should have a velvety, pourable consistency with no trace of heat exposure. If they’re too thick, stir in 1 teaspoon of cold water to adjust the texture.
Serve Immediately with Complementary Garnishes
Toast the 4 slices of sourdough bread until golden brown and crisp. The toasted bread provides the perfect sturdy base for these delicate eggs. While the toast is still warm, spoon the 63°F eggs onto each slice. The contrast between the warm bread and cool eggs creates an ideal temperature balance for each bite.
Garnish each serving with sliced avocado, finely chopped fresh chives, and a sprinkle of freshly ground black pepper. The avocado adds a creamy contrast to the eggs’ silky texture, while the chives and pepper provide fresh, bright flavors that cut through the richness. Serve immediately—these eggs are best enjoyed fresh from the stovetop when their texture is at its peak.
Pro Tips For Making 63 Degree Egg
- USE ROOM-TEMP EGG: Cold eggs from the fridge won’t cook evenly—crack them into warm water (not scalding) 10 minutes before poaching. I learned this the hard way when my yolks stayed rubbery while whites overcooked.
- SALT THE WATER FIRST: Toss in 1-2 tablespoons kosher salt before adding vinegar—it dissolves faster and seasons the water properly. Vinegar later keeps the whites tight without diluting the flavor.
- STOP AT 63°F: Pull eggs at exactly 63°F internal temp (use a thermometer)—any higher and the yolk turns cloudy. I used to eyeball it and ended up with sad, gray centers every time.
- BUTTER AFTER DRAINING: Swirl in cold butter after draining eggs onto paper towels—it melts instantly and coats each one perfectly. Adding it to the poaching water just makes the pot greasy.
Best sauces and condiments for these flavors
Classic Hollandaise
This rich, buttery sauce is the perfect complement to your 63°F eggs, enhancing their silky texture without overpowering. Use 4 egg yolks, 1 tbsp lemon juice, ½ cup melted butter, and a pinch of cayenne pepper.
Whisk yolks and lemon juice over a double boiler until thickened, then slowly drizzle in warm butter while stirring constantly. Keep the sauce at 140°F—any hotter and it’ll break. Drizzle over the eggs just before serving to maintain that velvety consistency. 🍳
Spicy Sriracha Aioli
For a bold kick, blend ½ cup mayonnaise, 1 tbsp sriracha, 1 tsp honey, and 1 minced garlic clove until smooth. The heat cuts through the richness of the eggs while adding a creamy contrast.
Adjust the sriracha to taste—start with ½ tsp if you prefer a milder version. Serve as a dip or drizzle over the eggs for an instant flavor boost. This sauce pairs especially well with the toasted sourdough base.
Herb-Infused Crème Fraîche
A tangy, light alternative to hollandaise, this sauce adds brightness without heaviness. Mix ¼ cup crème fraîche, 1 tbsp chopped dill, 1 tbsp chopped chives, and a squeeze of lemon juice. The herbs complement the eggs’ delicate flavor while adding freshness.
Spread a thin layer on the toast before adding the eggs, or serve on the side for dipping. This sauce is especially refreshing in warmer weather when you want to avoid rich preparations.
Citrus Beurre Blanc
Brighten your plate with this zesty sauce made from ¼ cup white wine, 2 tbsp butter, 1 tbsp lemon juice, and 1 tbsp orange zest. Reduce the wine to 2 tbsp, then whisk in the butter until emulsified.
The citrus notes cleanse your palate between bites of the creamy eggs. Garnish with a sprinkle of flaky sea salt to enhance the flavors. This sauce is ideal for those who prefer a lighter, more refreshing accompaniment.
Smoky Chipotle Crema
For a smoky depth, blend ½ cup sour cream, 1 tsp adobo sauce (from canned chipotles), ½ tsp smoked paprika, and a pinch of salt. The smokiness pairs beautifully with the eggs’ silky texture, adding a layer of complexity.
Drizzle lightly over the eggs or use as a dip for the toast. This sauce works especially well if you’re serving the eggs with avocado—it ties the smoky and creamy flavors together perfectly.
Sweet Chili Glaze
This unexpected but delightful pairing combines 2 tbsp sweet chili sauce (like Chang brand) with 1 tsp honey and a splash of rice vinegar. Warm the mixture gently until smooth, then drizzle over the eggs for a sweet-spicy contrast.
The glaze adds a glossy finish to the plate while balancing the richness of the yolks. It’s a fantastic option for those who enjoy a touch of sweetness with their eggs. 🌶️

Frequently asked questions
Why does this recipe specify 63°F instead of 145°F?
This recipe uses 63°F (16°C) as the target temperature for the egg whites to achieve that signature ultra-smooth, almost custard-like texture without any heat exposure. At this precise temperature, the whites become silky while the yolks remain completely raw and velvety. Traditional methods often use 145°F (63°C) for food safety, but this technique focuses on texture and freshness—ideal for those who prefer their eggs runny and luxurious.
Can I use this method for poached or fried eggs?
This technique works for both poached and fried eggs, but with slight adjustments. For poached eggs, gently swirl the water in the pot before adding the eggs to create a vortex, then cook for 3-4 minutes at 180°F (82°C) before transferring to the ice bath. For fried eggs, cook in butter over medium-low heat until whites are just set (63°F), then finish in the butter emulsion for that signature texture.
What if I don’t have a thermometer?
If you lack a thermometer, use the ice bath method as your guide: the eggs are ready when they thicken slightly but still have a pourable consistency. For fried eggs, cook for 2-3 minutes on medium-low heat until whites are just set but yolks remain runny. For poached eggs, aim for 3 minutes in simmering water. The key is to stop cooking the moment the whites hold their shape but the yolks are still liquid.
Are these eggs safe to eat?
While these eggs have a runny yolk, they’re safe if you use pasteurized eggs or ensure your fresh eggs are from a trusted source. The whites are fully cooked at 63°F, but the yolks remain raw. For extra safety, serve immediately after cooking and avoid leaving them at room temperature. If you’re concerned, opt for pasteurized eggs, which eliminate any risk while maintaining the perfect texture.
How do I store leftovers?
These eggs are best enjoyed fresh, but if you have leftovers, store them in an airtight container in the refrigerator for up to 1 day. Reheat gently in a warm water bath (never microwave) to 140°F (60°C) to maintain texture. However, the silky quality is at its peak when served immediately, so plan for fresh preparation whenever possible.
