Jammy boiled eggs have set whites and glossy, soft yolks that are thick enough to spoon but still creamy. They are made by gently lowering eggs into simmering water, timing the cook, then chilling them promptly; the method is simple, and a timer makes the results more consistent.
Ingredients
- 4 large eggs, preferably cold from the refrigerator (about 200 g without shells)
- 8 cups water (1.9 L), or enough to cover the eggs by at least 1 inch (2.5 cm)
- 4 cups ice (about 560 g) and 4 cups cold water (950 ml), for an ice bath
- Fine salt, for serving (optional; about ⅛ teaspoon / 0.5 g per egg)
Instructions
- Prepare the ice bath. Add the ice and cold water to a medium bowl and set it beside the stove. The bath should be ready before the eggs finish cooking, so you can stop the cooking promptly.
- Bring the water to a boil. Pour 8 cups (1.9 L) water into a saucepan large enough to hold the eggs in one layer. Bring it to a full boil over high heat, then reduce the heat slightly so the water is bubbling but not violently rolling.
- Lower in the eggs. Use a slotted spoon to lower the cold eggs into the water one at a time. Keep them in a single layer and make sure they are covered. Start the timer as soon as the last egg enters the water; if the boil pauses briefly, keep the heat up and time from that point.
- Cook for 7 minutes. Maintain a steady, gentle boil for 7 minutes for set whites and soft, jammy yolks. This timing is a starting point for large, refrigerator-cold eggs; egg size, starting temperature, pan, altitude and burner can affect the result. For a slightly firmer yolk, cook 30–60 seconds longer; for a looser center, try 6 minutes 30 seconds.
- Chill immediately. Transfer the eggs straight to the ice bath. Leave them there for at least 7 minutes, until cool to the touch. This stops carryover cooking and makes the eggs easier to peel. The USDA FSIS guidance for whole boiled eggs is to cook until the yolk and white are firm; jammy eggs have soft yolks and do not meet that fully firm endpoint. For people at higher risk from foodborne illness, serve fully cooked eggs with firm yolks, or choose pasteurized eggs and follow package directions.
- Peel and serve. Tap each egg gently on the counter, roll it to crack the shell, and peel under a thin stream of cool water if needed. Slice in half or leave whole, and season with salt just before serving.
Tips
- Use a timer and consistent eggs. Large eggs cooked straight from the refrigerator give a useful baseline. If using medium or extra-large eggs, adjust the time in small increments and note what works with your pan and stove.
- Lower them gently. Dropping eggs into the pan can crack the shells. A slotted spoon limits impact; keeping the water at a steady, gentle boil helps prevent eggs from bouncing against the pan.
- Don’t skip the ice bath. A quick chill arrests cooking, keeping the yolks soft instead of letting them firm up while the eggs sit hot. If you do not have ice, use very cold tap water and refresh it as it warms, though cooling may take longer.
- Peel with care. Very fresh eggs can be more difficult to peel. Cracking the shell all over and peeling from the wider end, where an air pocket often sits, can help; a little shell sticking is normal.
Serving Suggestions
Serve the eggs warm or chilled, sliced over buttered toast, avocado toast, or a bowl of rice. They also make a satisfying topping for ramen, noodle soup, grain bowls, roasted vegetables, or a leafy salad. Add them to the dish just before serving so the yolks remain visible and creamy.
For a simple snack, halve an egg and add flaky salt, black pepper, chili crisp, or a few drops of soy sauce. On toast, a thin layer of mustard or mayonnaise pairs well with the mild egg. If adding a halved egg to hot soup, place it in the bowl at the end rather than simmering it in the broth, which can overcook the yolk.
Variations
- Different yolk texture: Use the suggested 6 minutes 30 seconds for a looser yolk or 7 minutes 30 seconds to 8 minutes for a thicker, more set center. Treat these as adjustments to test with your own eggs and equipment.
- Seasoned finish: Sprinkle with smoked paprika, sesame seeds, chopped chives, or furikake. These are serving additions, not ingredients needed to cook the eggs.
- Soy-marinated eggs: After peeling, refrigerate the eggs in a mixture of ¼ cup soy sauce (60 ml), ¼ cup water (60 ml), and 1 teaspoon sugar (4 g) for 2–4 hours. The whites will take on a savory, salty flavor; keep the container refrigerated and do not leave it at room temperature.
- Use another egg size: Medium eggs may need a little less time and extra-large eggs a little more. Change the timing gradually—about 30 seconds at a time—rather than assuming the large-egg timing will work exactly.
Storage and Reheating
For best quality, serve jammy eggs soon after cooking. Refrigerate eggs within 2 hours of cooking, in a covered container at 40°F (4°C) or colder. Peeled eggs can be stored submerged in clean water in a sealed container; change the water daily. Use refrigerated hard-cooked eggs within 1 week, but soft-yolk eggs are best eaten within 1–2 days because the yolk remains less fully cooked. Discard eggs left at room temperature for more than 2 hours, or more than 1 hour when the temperature is above 90°F (32°C).
Reheating is not recommended: microwave heating can make an egg burst, and warming it through will continue to cook the yolk. If you want a warm egg, place a peeled, refrigerated egg in hot (not boiling) water for a few minutes and serve immediately; the center may firm further. For safety, leftovers that are reheated should reach 165°F (74°C), which will make a jammy yolk fully cooked. Do not reheat an egg in its shell in a microwave.
Frequently Asked Questions
How long do I boil eggs for a jammy yolk?
For large, cold eggs, start with 7 minutes in gently boiling water, then chill promptly in an ice bath. Add or subtract 30–60 seconds to suit your preference and equipment. The yolk should be thick and glossy rather than fully firm.
Should the eggs start in cold or boiling water?
This recipe starts eggs in already-boiling water because it provides a clear, repeatable timing point. Lower them in gently and start the timer when the last egg enters. Starting in cold water can work, but the time depends more on pan size, water volume and how quickly the water heats.
Why did my eggs crack?
Eggs may crack if they are dropped into the pan, the water boils too vigorously, or the shells have tiny flaws. Lower them with a spoon, keep the water at a steady gentle boil, and avoid crowding. A small crack does not necessarily make an egg unusable, but cook and chill it promptly.
Can I make jammy eggs ahead?
Yes. Chill them immediately after cooking, then refrigerate them in their shells in a covered container. For the best texture, use within 1–2 days. Peel shortly before serving, or peel ahead and keep the eggs covered and refrigerated.
Are soft-boiled eggs safe for everyone?
No cooking method that leaves the yolk soft reaches the USDA FSIS whole-egg endpoint of a firm yolk and white. People at higher risk of serious foodborne illness—including young children, older adults, pregnant people and those with weakened immune systems—should choose fully cooked, firm-yolk eggs or use pasteurized eggs according to their package instructions.
Can I use eggs straight from the refrigerator?
Yes. The 7-minute timing is written for large eggs taken cold from the refrigerator. Using room-temperature eggs can change the result, so keep the starting temperature consistent when adjusting the timing for your preference.
