Boiled eggs are already a staple for anyone trying to stay low-carb. But plain eggs every day? That gets old, real quick. Now imagine those same eggs soaking in salty, slightly sweet soy sauce with garlic and a hint of spice. The whites take on this deep brown color, and the flavor? So much better than it should be for something this easy.
This is one of those recipes where you do the work once, and you’re set for the next few days. You’ll find yourself grabbing one from the fridge as a snack, adding it to salads, or slicing it onto cauliflower rice. It’s low-effort, high-payoff cooking.
And if you’ve been doing keto for a while, you know the struggle of always needing more fat and flavor without the carbs. These eggs solve that problem.
Let’s get into it.
What Are Soy Sauce Eggs Anyway?
These are known in China as Lu Dan (卤蛋). In Japan, you’ll see something similar called Shoyu Tamago. It’s a boiled egg soaked in a soy sauce-based marinade. In China, they’re usually stewed in a mix of soy sauce, star anise, cinnamon, garlic, and a few other things that make your kitchen smell like comfort.
In this keto version, we make one small change: no sugar. That’s the only switch. Everything else stays true to the flavors. And no, you don’t need to be a pro cook to pull this off.
What You Need
Let’s keep this basic. No weird stuff, no trips to five stores. Everything should be easy to find or swap.
Ingredients:
- 6 large eggs
- ½ cup soy sauce (go for low sodium if you want more control)
- ½ cup water
- 2 tablespoons apple cider vinegar or rice vinegar (either works)
- 1 teaspoon sesame oil (optional but tasty)
- 2 garlic cloves, smashed
- 1 piece of star anise (optional but worth it)
- ½ teaspoon chili flakes or 1 small dried chili (optional if you like a kick)
- ½ teaspoon black pepper
- 1 tablespoon monk fruit sweetener or erythritol (don’t skip this—it replaces sugar from the traditional version)
That’s it. You can also toss in a cinnamon stick or a piece of ginger if you’re feeling extra.
How to Make your Keto Soy Sauce Boiled Eggs
This is the kind of recipe where the steps feel almost too easy. But that’s the beauty of it.
Step 1: Boil the Eggs
Bring a pot of water to a boil. Gently lower your eggs in with a spoon (don’t drop them, unless you enjoy cracked egg drama). Boil for 6–7 minutes for soft yolks or 9–10 minutes if you like them hard.
Once done, transfer them into an ice bath or just cold tap water. Let them chill for 10 minutes. Peel carefully.
Step 2: Make the Marinade
In a small saucepan, combine soy sauce, water, vinegar, sesame oil, garlic, star anise, sweetener, pepper, and chili. Bring it to a simmer. Stir until the sweetener dissolves. Let it bubble for about 5 minutes, then take it off the heat and let it cool down.
Step 3: Marinate the Eggs
Put the peeled eggs in a container or a zip-top bag. Pour the cooled marinade over them. Make sure the eggs are mostly covered. If not, you can rotate them once or twice a day.
Let them soak in the fridge for at least 6 hours, but overnight is better. Two days? Even better. The flavor gets stronger, and the outside of the egg turns this dark, savory brown.
Why Keto People Love These Eggs
There’s a reason these eggs have made their way into every meal prep guide out there. If you’re doing keto, they hit all the right notes:
- Low in carbs: Literally zero carbs if you skip the sweetener or use a sugar-free one.
- High in fat and protein: Especially when you use a soft yolk. Add some mayo or avocado, and you’re golden.
- Filling: One egg can keep you full for hours.
- Meal-prep friendly: They last about 4–5 days in the fridge.
You don’t need to eat like a caveman to stay in ketosis. These eggs prove that.
How to Use These Eggs (Not Just for Snacking)
You can eat these straight from the fridge, but they also make boring meals way better. Here are some ways to use them:
- Slice on top of a keto ramen bowl with shirataki noodles
- Add to cauliflower fried rice
- Serve with steamed or stir-fried bok choy
- Chop and mix into keto egg salad with mayo and scallions
- Smash on low-carb toast with a drizzle of chili oil
- Add to a bento-style lunch box with pickled veggies and grilled chicken
- Serve with avocado and a sprinkle of furikake for a fast lunch
Basically, they go with everything. You’ll keep finding new uses every time you open the fridge.
Personal Story – The Egg That Saved My Week
The first time I made these eggs, I had just bombed a week of keto. Gave in to takeout, felt like trash, and needed to reset. Didn’t have much energy or willpower, but I had eggs. Found an old recipe from a friend in Shanghai, tweaked it to skip the sugar, and threw it all together.
Next day? I pulled one out, cut it open, and the yolk was golden and just a little soft. That salty-soy smell hit first. One bite and I was back on track. That’s when I knew—this one was staying in my meal prep rotation forever.
Tips and Shortcuts
- Eggs too hard or soft? Just adjust the boiling time by a minute or two next round.
- Too salty? Add more water to the marinade next time or use low-sodium soy sauce.
- No monk fruit or erythritol? You can skip it. The flavor won’t be as close to the original, but it’ll still be solid.
- Want a shortcut? Skip the simmering step and just mix everything cold. It works. Not as deep in flavor, but still tasty.
- Batch it: Double the recipe and make 12 at once. They keep well, and you’ll thank yourself later.
How Long Do They Last?
These keep in the fridge for up to 5 days if you use a clean container and keep them cold. After that, the flavor gets too strong and the whites start to change texture.
Conclusion
These eggs aren’t fancy. They’re not trendy. But they hit the spot. Every time. If you’re someone who meal preps, stays low carb, or just wants to eat better without overthinking it, this is your go-to.
People scroll Pinterest all day for the next “easy low carb snack” or “keto meal prep idea,” and this one sits quietly in the back like—“I’ve been here the whole time.”
So next time you’re standing in front of the fridge, wondering what you can eat without blowing your macros or breaking the bank, just grab one of these eggs. That’s it.
