Easy Homemade Chashu Pork with Ajitama
If you love a bowl of Japanese ramen topped with tender, savory-sweet pork and a perfectly seasoned soft-boiled egg, this recipe is for you!
Chashu pork is rich, flavorful, and surprisingly easy to make at home, Japanese chashu is a versatile ingredient that takes so many dishes to the next level. Use it as a topping for ramen, serve it over steamed rice to make chashu-don, or add it to fried rice for an extra boost of flavor.
And here's my favorite trick: you can make ajitama (Japanese seasoned ramen eggs) using the very same sauce as the chashu pork! The pork simmers in a savory-sweet mixture of soy sauce, sake, sugar, and aromatics, creating a delicious cooking liquid that doubles as a marinade for boiled eggs.
It's an easy way to prepare two classic ramen toppings at once, with less work and plenty of flavor.
What Is Chashu Pork?
Chashu is a popular braised pork commonly served as a topping for ramen. It's known for its tender texture and rich, savory-sweet flavor.
Although Japanese chashu was inspired by Chinese char siu, the two dishes are prepared differently. Traditional Chinese char siu is typically roasted and often has a distinctive reddish glaze, while Japanese chashu is commonly braised in a soy sauce-based liquid until tender and flavorful.
Pork belly is a popular choice because its layers of meat and fat create a rich, melt-in-your-mouth texture. The braising liquid typically includes soy sauce, sake, sugar, ginger, and garlic, giving the pork its signature Japanese flavor.
Homemade chashu is especially delicious because you can adjust the sweetness and seasoning to your liking. Once you try making it from scratch, you may never look at your ramen bowl the same way again!
What Is Ajitama?
Ajitama, short for ajitsuke tamago, means seasoned egg in Japanese. These flavorful eggs are a familiar topping at ramen shops throughout Japan.
Ajitama is usually made by soft-boiling eggs and marinating them in a savory seasoning liquid. The whites absorb the flavor while the yolks remain creamy and rich.
In this recipe, we'll use the chashu cooking sauce to season the eggs. It's a simple way to make your own ramen eggs while preparing the pork, without making a separate marinade.
For the best results, use peeled boiled eggs and let them soak in the cooled chashu sauce in the refrigerator until they reach your preferred flavor. The longer they marinate, the more flavorful they become.
How to Serve Homemade Chashu Pork
One of the best things about homemade chashu is how many ways you can enjoy it. Here are a few of my favorite ideas.
Chashu ramen: Add thin slices of pork and a halved ajitama to your favorite bowl of Japanese ramen.
Chashu-don: Serve the pork over warm Japanese rice with a drizzle of sauce and a soft-boiled egg.
Chashu fried rice: Chop leftover pork into small pieces and stir-fry with rice, eggs, scallions, and your favorite seasonings.
Chashu rice bowls: Pair the pork with steamed rice, sautéed vegetables, and a little extra sauce for an easy meal.
If you make a batch ahead of time, you'll have a delicious topping ready to turn a simple meal into something special.
The Story of Chashu
Japanese chashu traces its culinary roots to Chinese char siu, a traditional roasted pork dish whose name refers to the method of roasting meat on skewers. As Chinese culinary traditions influenced Japanese cooking, particularly in port cities such as Yokohama and Kobe, the dish evolved to suit local tastes.
Unlike traditional Chinese char siu, which is typically roasted, Japanese chashu is commonly prepared by braising pork in a mixture of soy sauce, sake, sugar, and other seasonings. It became especially popular as ramen spread throughout Japan during the 20th century, eventually becoming one of the most recognizable toppings in a bowl of ramen.
Today, chashu is a beloved part of Japanese ramen culture, with each ramen shop often having its own approach to the cut of pork, seasoning, and cooking method. Making it at home is a wonderful way to bring a little of that ramen-shop experience into your own kitchen.
RECIPE
Servings: 4-5
Time: 60 min
Ingredients:
1.5 lb pork belly block
1/4 cup sake
1/4 cup sugar
1/2 cup soy sauce
1 cup water
2 cloves garlic, sliced
3-4 slices ginger
2 scallions
boiled eggs
Instructions:
Brown the pork belly.
Heat a pan or a pot over medium-high heat.
Place the pork belly in the pan and sear each side until golden brown.
Carefully drain excess rendered fat if needed.
Add the sauce.
Add the sake, sugar, soy sauce, water, sliced garlic, ginger, and scallions.
Simmer the pork.
Bring the liquid to a gentle simmer, then reduce the heat to low.
Cover and simmer for 40–50 minutes, turning the pork occasionally so it cooks evenly and absorbs the sauce.
Make sure the liquid maintains a gentle simmer rather than a rapid boil.
Prepare the ajitama.
While the pork cooks, prepare your boiled eggs. (I cook 9 minutes)
Transfer them to an ice bath and peel carefully.
Add the eggs to the pot, simmer another few minutes.
You can also separate some sauce to another container just to marinate the eggs.
FAQ
1. What cut of pork is best for chashu?
Pork belly is a popular choice because its layers of fat and meat create tender, flavorful slices. Pork shoulder can also be used if you prefer a leaner option, although the texture will be different.
2. Can I make chashu pork without tying it?
Yes! Tying the pork belly with kitchen twine helps it maintain a round shape, especially if you want neat, spiral slices for ramen. However, it isn't necessary for this easy home-style recipe. You can cook the pork belly as it is.
3. Can I make ajitama with the same sauce?
Absolutely! That's one of the best parts of this recipe. The eggs will absorb the savory-sweet flavor of the braising liquid.
For food safety, refrigerate the sauce promptly and use clean utensils and containers. If you plan to reuse the sauce as a marinade, bring it to a full boil first, then cool it safely before refrigerating the eggs in it. Never reuse sauce that has been left at room temperature for an extended period.
4. How long should I marinate ajitama?
For a lightly seasoned egg, try a few hours. For a deeper flavor, marinate overnight in the refrigerator. The longer the eggs sit in the sauce, the more seasoning they absorb.
5. Can I make chashu pork ahead of time?
Yes! Chashu is a great make-ahead dish. Once cooked, refrigerate it promptly in a covered container. You can slice it when you're ready to serve, or gently reheat the slices in a little of the sauce.
6. How do I store homemade chashu pork?
Store the cooked pork in an airtight container in the refrigerator and use it within 3–4 days. For longer storage, freeze it in individual portions with a little sauce for up to 2–3 months for best quality.
7. Can I freeze chashu pork?
Yes. Slice the pork or keep it in a larger piece, then freeze it with a little of the cooking sauce in an airtight freezer-safe container. Thaw it in the refrigerator and reheat thoroughly before serving. For the best texture, freeze the pork separately from the ajitama.
8. What can I do with leftover chashu sauce?
The sauce is packed with savory-sweet flavor and can be used to season rice bowls or fried rice. If you want to reuse it, strain out the solids and bring the liquid to a full boil before using it in another dish. Refrigerate it promptly and avoid keeping it indefinitely, since it has been used to cook pork.
