Breakfast & Brunch
This spinach salted egg century egg recipe transforms bold flavors into a dish that bridges tradition and innovation—where crispy century eggs meet silky salted yolks and vibrant spinach.
The secret lies in balancing textures: crunchy century eggs (preserved for months in alkaline brine) contrast with creamy salted egg yolks, while wok-hei technique infuses the spinach with smoky depth.
What makes this dish special is how it reimagines classic Chinese ingredients for modern palates, delivering umami in every bite without sacrificing authenticity.
The magic happens in the stir-fry: high-heat searing of century eggs creates a satisfying crunch, while salted egg yolks melt into the spinach, adding richness without overpowering. Traditional methods like double-boiling the eggs ensure safety, but this recipe simplifies the process for home cooks—no specialized equipment required.
The result? A dish that’s restaurant-worthy yet approachable, perfect for brunch or as a standalone vegetarian-friendly meal (despite the eggs).
By the time you plate it—crispy eggs atop tender spinach, drizzled with a light soy-ginger glaze—you’ll understand why this dish is a favorite in Cantonese cuisine. The contrast of temperatures (room-temperature eggs, wok-hot spinach) and textures (crunch vs. silky) makes each forkful unforgettable.
Whether you’re serving guests or treating yourself, this recipe delivers bold, balanced flavors with minimal effort.
For extra flair, garnish with toasted sesame seeds or chili oil to amplify the umami. The dish keeps well for 2 days, making it ideal for meal prep—just reheat gently to preserve the crispiness. Let’s bring this umami-packed masterpiece to your table.

Century eggs are the heart of this dish—look for plump, dark-skinned eggs with no cracks or leaks. Asian grocery stores like H Mart or 99 Ranch carry them year-round, but if unavailable, substitute duck eggs preserved in brine for 3 weeks (double the salt). Salted egg yolks should be creamy and rich—if they smell ammonia-like, discard. For the spinach, organic baby spinach holds its texture better than pre-washed varieties. Trader Joe's often has excellent quality at a reasonable price, but any tightly packed leaves will work.
No century eggs? Preserve your own duck eggs (3 weeks in 10% salt brine) or use high-quality salted duck eggs from a trusted source. Substitute vegan umami paste (like Miso Master) for depth if omitting eggs entirely. For the spinach, bok choy or Swiss chard work in a pinch, but texture will differ. The soy sauces matter—Kikkoman light and Lee Kum Kee dark provide the perfect balance. Fresh ginger and garlic must be finely minced for proper infusion; pre-minced jars lack potency. Toasted sesame oil is non-negotiable for aroma—Kadoya brand is a reliable choice.
Century eggs and salted yolks keep indefinitely at room temperature once preserved, but spinach should be refrigerated in a sealed container for up to 5 days. The stir-fry reheats beautifully—2 minutes in a wok restores wok-hei. For meal prep, store components separately: eggs and yolks in one container, cooked spinach in another. Reheat spinach gently to 165°F before combining. Garnishes like sesame seeds and chili oil can be added fresh when serving. The dish tastes even better the next day as flavors meld.

Step-by-step instructions for century egg and spinach stir-fry
This dish balances rich, preserved eggs with delicate spinach using precise timing and technique.
Prepare the Century Eggs and Salted Egg Yolks
Peel the 4 whole Century Eggs carefully, removing the black membrane that surrounds each egg. Cut each egg in half lengthwise, then separate the yolks from the whites. Set aside the yolks—they're the star of this dish. The whites will add texture but should be handled gently to preserve their delicate structure.
Crack the 4 whole Salted Egg Yolks and separate them from any remaining whites. You'll have a total of 8 yolks to work with. These yolks will provide the signature creamy, salty contrast that defines this dish. Keep all yolks at room temperature for even cooking.
Create the Spinach Sauce Base
In a small bowl, whisk together the 1 tsp cornstarch with 0.5 cup vegetable stock until fully dissolved. This slurry will create a silky coating for the spinach. Heat 1 tbsp neutral oil in a wok or large skillet over medium-high heat until shimmering.
Add the 8 oz baby spinach all at once and stir-fry for 1-2 minutes until just wilted but still vibrant green. Pour the cornstarch slurry into the pan and stir continuously for 30 seconds until the spinach is fully coated and glossy. Remove from heat and set aside—this sauce should be tender-crisp, not mushy.
Build the Flavor Foundation
In the same pan, add 1 tbsp neutral oil and heat over medium heat. Add the 2 cloves minced garlic and 1 tbsp finely grated fresh ginger, cooking for 30 seconds until fragrant but not browned. Add 1.5 tbsp light soy sauce and 0.5 tbsp dark soy sauce, stirring to combine. The dark soy sauce will give the dish its signature deep color.
Pour in 1 tbsp rice vinegar and 1 tsp chili oil (if using), stirring to distribute evenly. The vinegar brightens the dish while the chili oil adds subtle heat. Keep the mixture at a gentle simmer—this will infuse the sauce with layered flavors without overpowering the delicate spinach and eggs.
Combine and Finish
Return the spinach mixture to the pan and gently fold in the 8 Century Egg yolks and 4 Century Egg whites. Add the 1 tbsp toasted sesame seeds and 1 tbsp sesame oil, tossing everything together for 1 minute over low heat. The sesame oil should perfume the dish immediately, while the sesame seeds add satisfying crunch.
Taste and adjust seasoning with additional soy sauce or rice vinegar if needed. The dish should balance umami from the eggs, saltiness from the yolks, and brightness from the vinegar. Serve immediately while the spinach maintains its vibrant color and the eggs remain creamy.
Pro Tips For Making Spinach Salted Egg Century Egg
- STIR-FRY SPINACH FAST: I used to wilt spinach until it turned to mush—just toss it in for 10 seconds with the eggs, then pull it out. Baby spinach wilts instantly, and you want it bright green, not sad and limp. (Yes, even if you're impatient like me.)
- PEEL CENTURY EGGS CLEVERLY: Skip the messy peeling—crack the century eggs into a bowl first, then use a spoon to scoop out the yolks and discard the blackened membrane. The yolks will be cleaner, and you avoid the sticky, inedible bits that ruin the texture.
- SALT EGGS LAST MINUTE: Add the salted egg yolks only at the very end—right when you plate. If you cook them in the wok, they’ll turn rubbery from the heat. Instead, keep them cool until serving, then let guests mix them into their spinach for that perfect salty-sweet contrast.
- USE SESAME OIL SPARINGLY: A single teaspoon of sesame oil at the end is enough—any more, and the dish smells like a Chinese restaurant’s takeout menu. Drizzle it over everything just before serving, then toss gently. (Your nose will thank you.)
Dietary considerations for these flavors
Vegetarian-Friendly Adaptations
While this dish traditionally includes eggs, the core technique—stir-frying spinach with umami-rich elements—works beautifully for vegetarians. Swap the salted and century eggs for mushroom umami paste (like Miso Master) or fermented black beans (soaked and mashed).
For texture, add crispy fried tofu or shredded napa cabbage—both mimic the eggs' contrast. 🌱
Gluten-Free Considerations
Standard soy sauce contains gluten, so opt for tamari or gluten-free soy sauce (like San-J Tamari) instead of Kikkoman. Dark soy sauce is also gluten-containing, so replace it with extra dark sesame oil (1 tsp) for color depth.
Ensure your vegetable stock is certified gluten-free, as some brands use wheat-based thickeners. 🥢
Allergen Safety
Sesame is a common allergen, so check labels on sesame oil and sesame seeds—brands like Kadoya often list allergen info. For nut-free kitchens, toast sunflower seeds (1 tbsp) instead of sesame seeds.
If shellfish allergies are a concern, ensure your vegetable stock is shellfish-free (some brands use fish-based flavorings). Always verify labels, as cross-contamination risks exist in shared facilities. ⚠️
Low-Sodium Options
Reduce sodium by using low-sodium soy sauce (like Kikkoman Low-Sodium) and homemade vegetable stock (simmer 2 carrots, 2 celery stalks, and 1 onion in 4 cups water for 20 minutes). Skip the salted egg yolks entirely and substitute with avocado slices for creaminess.
Balance flavors with extra rice vinegar (1.5 tbsp) and fresh ginger (1.5 tbsp grated) to maintain depth. 💡
Protein Boost
Add edamame (½ cup shelled) for plant-based protein—blanch for 1 minute, then fold into the spinach. For extra richness, stir in silken tofu (½ cup cubed) during the final 1 minute of cooking. These additions keep the dish vegetarian while enhancing texture and nutrition. 💪

Frequently asked questions
What's the difference between salted egg yolks and century egg yolks in this recipe?
Salted egg yolks are creamy and salty from being preserved in brine, while century egg yolks have a deep umami flavor from their alkaline curing (3+ months!). The recipe uses both for layered texture: century egg whites add crunch, and salted yolks provide richness. The contrast makes every bite exciting!
Can I substitute regular eggs for salted/century eggs?
Not recommended—they lack the umami depth and texture. For a similar effect, use duck eggs preserved in salt brine (3 weeks) for salted yolks, or quail eggs marinated in soy sauce (24 hours) for century egg vibes. The dish won't be identical, but it'll add complexity.
Why does the recipe call for both light and dark soy sauce?
Light soy sauce adds salty flavor, while dark soy sauce provides deep color and a slightly sweeter, molasses-like note. Together, they create the signature Cantonese umami balance. Skip dark soy sauce if gluten-free, but add 1 tsp extra sesame oil for color depth.
How do I store leftovers without making the spinach soggy?
Store components separately: spinach in one container, eggs in another. Reheat spinach alone for 2 minutes in a wok (no oil) to restore crispness, then mix with eggs. Keep eggs at room temp until serving—they shouldn't be reheated. Garnish fresh with sesame seeds and chili oil.
What's the best way to peel century eggs without breaking them?
Gently roll the egg between your palms to loosen the membrane, then tap the thin end with a spoon to crack it open. Peel under running water for easier removal. For extra care, soak peeled eggs in ice water for 5 minutes to firm up whites before cutting. The black membrane is edible but can be slippery—handle with care!
