Nikumaki Green Peppers (Japanese Pork Belly Wrapped Peppers with Cheese)

Nikumaki (肉巻き) means “meat-wrapped,” and this is one of the most popular versions in Japanese homes: green pepper halves stuffed with cheese, wrapped in thin slices of pork belly, pan-fried until crisp, and glazed in a sweet soy sauce of sake, mirin, and soy. The cheese melts inside, the pepper stays a little crunchy, and the pork belly gets caramelized edges.

I followed a recipe from Kurashiru, a popular Japanese recipe site, with the same amounts, and served it as the main dish of a set meal with rice and small sides. It’s a frying pan dinner that takes about 20 minutes, and the only slightly fiddly part is wrapping the pork around the peppers. We used a bag of shredded pizza cheese, the white and orange mix you can buy at any Japanese supermarket.

The Short Answer

If you just want the method:

• What it is: nikumaki is a Japanese home dish of vegetables wrapped in thinly sliced meat. This version wraps cheese-stuffed green peppers in pork belly.
• For 2 servings: 3 green peppers (6 halves), 100g shredded cheese, 300g thinly sliced pork belly, and a sauce of 1 tbsp each sake, mirin, and soy sauce.
• The method: fry seam-side down until browned, flip, cover and cook for 3 minutes on medium heat, then season with salt and pepper and glaze with the sauce.
• The trick: start with the end of the pork wrap facing down. It seals in the pan, so the rolls don’t come apart.

Why You’ll Love This Recipe

• Melty cheese inside. The cheese melts into the pepper, so every bite is rich and gooey.
• Three-ingredient sauce. Sake, mirin, and soy sauce in equal amounts — the classic Japanese sweet soy glaze.
• One frying pan, 20 minutes. No oven, no deep-frying.
• Gets people to eat green peppers. Japanese green peppers are known as the vegetable kids won’t eat; cheese and pork are how parents get around that.

What is Nikumaki?

Niku means meat and maki means rolled or wrapped. Nikumaki is a whole family of Japanese home dishes where thin slices of pork or beef are wrapped around something — green beans, asparagus, enoki mushrooms, rice balls, or, like here, green peppers. Because Japanese supermarkets sell meat sliced paper-thin, wrapping it around vegetables is an everyday weeknight trick, and nikumaki is a lunchbox and dinner regular.

Japanese Green Peppers (Piman)

Japanese green peppers, called piman, are smaller than American bell peppers, with thinner walls and a slightly more bitter taste. Halved, each one is just the right size to wrap with one slice of pork. In the US, small green bell peppers or mini sweet peppers are the closest match. I haven’t tried this with either, so cut big bell peppers into quarters instead of halves to keep the size similar.

Ingredients (Serves 2)

Ingredient	Amount	Notes
Japanese green peppers	3	Halved, seeds removed (6 halves)
Shredded pizza cheese	100g (about 1 cup)	A mozzarella and cheddar mix works well
Thinly sliced pork belly	300g (about 10 oz)	6 long slices
Salt and pepper	A pinch
Vegetable oil	½ tbsp
Sake	1 tbsp	For the sauce
Mirin	1 tbsp	For the sauce
Soy sauce	1 tbsp	For the sauce

The sauce is the classic 1:1:1 of sake, mirin, and soy sauce. Our soy sauce is a sweet Kyushu one, which makes the glaze a little sweeter; with regular soy sauce it’s slightly saltier, so taste before you add it all. For the pork, look for thinly sliced pork belly at an Asian supermarket. Most carry it frozen for hot pot.

How to Make Nikumaki Green Peppers

Step 1: Halve the Peppers and Fill with Cheese

Cut the green peppers in half lengthwise and remove the stems and seeds. Pack the shredded cheese into each half.

Step 2: Wrap with Pork Belly

Wrap one slice of pork belly around each pepper half, covering the cheese. Finish with the end of the slice on the bottom.

Save

Step 3: Fry Seam-Side Down

Heat the oil in a frying pan over medium heat. Put the rolls in seam-side down and fry until browned underneath. This seals the end of the pork so it stays wrapped.

Save

Step 4: Flip, Cover, and Cook for 3 Minutes

Turn them over, cover with a lid, and cook over medium heat for about 3 minutes, so the pork cooks through and the cheese melts.

Step 5: Season and Glaze

When both sides are browned, take off the lid and sprinkle with salt and pepper. Pour in the sauce and keep cooking over medium heat, turning the rolls, until the sauce thickens and coats them in a glossy glaze.

Step 6: Serve

Arrange on a plate and spoon any sauce left in the pan over the top. We had it as the main dish with rice and a couple of small sides.

Tips and Variations

• Some cheese will leak. A little melted cheese escaping and crisping in the pan is normal, and it’s tasty.
• Don’t skip the lid. Pork belly wrapped around a pepper is thicker than it looks, and the lid makes sure it cooks through.
• Other fillings. Without cheese, it’s a plain pork-wrapped green pepper, which is also very common. Green beans, asparagus, and enoki are classic nikumaki fillings too.
• Want it sweeter? Add a teaspoon of sugar to the sauce, like teriyaki chicken.

What to Serve It With

• Rice and miso soup, as the main dish of a Japanese set meal.
• A light vegetable side to balance the rich pork, like green pepper namul or a simple salad.
• Another pork favorite for a different night: Japanese ginger pork.

Storing and Reheating

Keep leftovers in the fridge for up to 2 days. Reheat in a frying pan or microwave until hot. They’re also good cold the next day, which is why nikumaki is a popular bento item in Japan.

Frequently Asked Questions

What does nikumaki mean?

Nikumaki means “meat-wrapped” in Japanese. It’s any dish where thin slices of meat are rolled around vegetables, rice, or other fillings and then pan-fried and glazed.

Can I use bacon instead of pork belly?

Bacon is the closest thing in a regular American supermarket. I haven’t tried it, but it’s already salty and smoky, so you’d want to cut back on the soy sauce.

Can I use bell peppers?

They should work, though I haven’t tried them myself. Bell peppers are bigger and sweeter than Japanese green peppers, so cut them into quarters to get pieces about the same size.

How do I keep the pork from unrolling?

Put the rolls in the pan with the end of the pork slice facing down, and don’t move them until that side is browned. The meat sticks to itself as it cooks.
