You can compare them to Padron peppers but there’s a catch: about one in every eight peppers is actually spicy!

When you eat blistered shishito peppers you have to take a small bite first to see if your pepper is the hot one of the bunch. Getting an occasionally spicy pepper is a fun surprise.

How to roast Japanese style blistered Shishito peppers [Recipe & Cooking tips]

Roasting shishito peppers is a quick process. All you have to do is drizzle them with olive oil and salt then roast them in the oven on very high heat – preferably under the broiler until they blister which takes only 10 minutes.

The roasted peppers are usually served with a creamy dipping sauce and this makes the perfect appetizer.

In this guide, I’m sharing everything you need to know about Japanese shishito peppers and showing you how to roast them so they’re blistered, soft, and ready to eat alongside your favorite Japanese dishes.

In this post we'll cover:

What are shishito peppers?

Shishito peppers are Japanese peppers from the Capsicum annuum chili peppers family. These peppers are considered to be mildly spicy and they’re used in a lot of Japanese recipes.

The peppers are long and thin, usually about two to three inches in length. They’re bright green when they’re young, but they turn red as they mature. Also, they have a wrinkly appearance.

As with Spanish padrón peppers, the blistering of shishitos is a popular tapas dish, but they’re a lot milder than jalapenos.

Blistering shishito peppers are commonly served as appetizers in Japanese restaurants. If you like to grill peppers, you’ll enjoy this roasted pepper snack.

And, since most shishito peppers are mild, it’s a crowd-pleasing appetizer. You might not even realize how quickly you can get through a small bowl of smoky peppers.

What does shishito mean?

The word shishito refers to this small type of pepper. But, shishito is also known as lion head peppers.

That’s because the Japanese word for lion, shishi, refers to the folded crease at the pepper’s tip that looks like a lion’s head.

Koreans call shishito peppers kkwari-gochu. This word means groundcherry pepper and the reason for this name is that the peppers look very wrinkly.

The name is thought to come from the fact that the peppers resemble a lion’s head.

The peppers are also sometimes called “bara shishito” which means rose pepper.

This is likely due to the fact that the peppers turn red when they’re ripe.

The word “blistered” in the name of the dish refers to the fact that the peppers are usually cooked until they blister and char. This is what gives the peppers their signature taste and texture.

What do shishito peppers taste like?

Japanese shishito peppers have a slightly sweet and smoky flavor with a touch of heat.

They’re not as spicy as other chili peppers, but about one in every eight peppers is actually hot.

How to roast shishito peppers

There are two ways to roast the shishito peppers so they’re nice and blistered: in the oven on high heat or on the stovetop in a cast-iron skillet.

Roasted peppers taste their best when they’re cooked quickly over high heat. The best way to make them blister and lightly charred is to cook them fast on high heat.

You’re going for charred blisters on all sides and a fairly firm texture. Premature wilting and softening occurs when the peppers are cooked too slowly or at a lower temperature.

I’m sharing a recipe and instructions on how to cook shishito peppers in oven first and then I’ll share how to cook shishito peppers in a pan on the stove.

Recipe notes

You don’t want to overcook the peppers. Keep a close eye on them because they cook quickly!

If you don’t want them to “inflate,” you can poke holes in them with a toothpick.

It’s not a good idea to reheat them after roasting them because they become mushy when reheated. Prepare only what you intend to consume.

If you have trouble knowing when the shishito peppers are done roasting here’s a tip.

Pull the peppers out of the oven and check them. They should have a white-ish color with brown char marks.

Now, you need to know that after coming out of the oven, the roasted peppers deflate like tiny balloons and shrink in size. They become tender and slightly crispy which is just how they should be.

Roasting shishito peppers in a cast-iron skillet or pan

Roasting shishito peppers is very easy and only takes a few minutes. All you need is a pan, some oil, and peppers. I like to use avocado oil because it has a high smoke point and it’s a healthy oil.

Before starting, poke small holes in the peppers using a toothpick.

First, heat the pan on medium-high heat. Then, add the oil and let it heat up for a minute. Add the peppers to the pan and cook them for two to three minutes, until they’re blistered.

Don’t forget to toss the peppers occasionally so they cook evenly on all sides. Once they’re blistered, remove the peppers from the pan and serve immediately.

There are a few things to keep in mind when roasting your peppers. First, make sure the pan is hot before adding the oil. If the pan isn’t hot enough, the peppers will absorb too much oil and they’ll be greasy.

Second, don’t overcook the peppers. They should be blistered, but not burnt. Once they’re burnt, they’ll be bitter and no one wants to eat that.

Finally, if you want to add some flavor to your peppers, try adding a bit of garlic, ginger, or even soy sauce to the pan before cooking the peppers.

Substitutions and variations

Olive oil and avocado oil are the best options when roasting shishito peppers in the oven or in a frying pan.

However, the savory and salty peppers also taste good when roasted with some peanut oil, sesame oil, or even grapeseed oil. It’s up to you since any vegetable oil will do the trick.

Usually, a high heat oil is the best but olive oil is an exception because it gives the peppers a really good flavor.

For the salt, you can use any coarse salt like sea salt, kosher salt, or Himalayan salt.

Roasted shishito peppers are a big deal in Japan – they’re on many appetizer menus. You can garnish and serve them in many ways.

Some people like to add sea salt and togarashi spice with a hint of lemon or lime juice.

Others prefer chili pepper flakes or a spicy chili pepper paste (yuzu kosho).

The most simple topping is a good old drizzle of sesame oil.

You can also add a drizzle of soy sauce or tamari if you want more flavorful peppers.

Many Japanese restaurants served the roasted peppers with a drizzle of miso sauce and this adds lots of umami flavors.

You can also top the peppers with toasted sesame seeds and some smoked paprika for additional flavor.

How to serve roasted shishito peppers

Eat the peppers as soon as possible after they’ve been removed from the heat, preferably with crunchy salt.

They will wilt and lose their crispiness even if they are cooked quickly and at high temperatures.

That’s just how peppers react when roasted so to enjoy them nice and crispy, serve with dipping sauce hot out of the oven or pan.

Keep in mind that not all shishito peppers are created equal. Some peppers will be mild while others will be quite spicy. It’s the nature of the pepper so don’t be surprised if you bite into a hot one.

That’s just part of the fun! When serving, it’s best to warn your guests that the peppers may be spicy.

The best way to serve shishito peppers is as an appetizer or side dish. They go well with grilled meats or fish, and they’re also a great snack on their own.

I like to serve roasted shishito peppers alongside yakiniku meats like grilled beef, chicken, or fish.

The roasted peppers are usually dipped into a tasty dipping sauce.

Origin of shishito peppers

You might be wondering what the origin of roasted blistered shishito peppers is. The peppers are a popular dish in Japan and they’ve been around for centuries.

The first recorded mention of the peppers was in the 15th century, but they likely existed long before that.

The peppers were originally grown in China, but they made their way to Japan via Korea.

What to dip shishito peppers in? The best dipping sauces revealed

You can go all out with dipping sauces but there’s a very simple dipping sauce you can pair with the roasted peppers and it’s very fresh and flavorful.

Mayo and yogurt sauce

For a really fresh, light, and tangy dipping sauce, combine mayonnaise (regular or Japanese Kewpie mayonnaise), yogurt, hot sauce, and a dash of lemon juice.

You can also substitute the yogurt with sour cream and use lime juice instead of the lemon juice.

Aioli (garlic) dipping sauce

This is a really simple dipping sauce that only requires four ingredients: mayonnaise, garlic, salt, and pepper.

Just combine all the ingredients in a bowl and mix until smooth. You can also use a food processor or blender to make this sauce.

Sriracha dipping sauce

This is another simple dipping sauce that only requires two ingredients: sriracha and mayonnaise. Just combine both ingredients in a bowl and mix until smooth.

You can also add a bit of lime juice or rice vinegar to this sauce to give it some acidity.

Some people add some minced garlic and red pepper flakes to make this a true restaurant-style dipping sauce.

Ranch dip

For a more classic dipping sauce, you can use ranch dressing. Just combine some store-bought ranch dressing with some chopped chives or green onions.

You can also add a bit of lemon juice or lime juice to this sauce.

Enjoy your roasted shishito peppers with any of these delicious sauces! And don’t forget to garnish with some sesame seeds, green onions, or cilantro before serving.

Cooked shishito peppers will last in the fridge for up to three days but they lose that crunchy crispiness and go mushy. I don’t recommend storing roasted peppers. Just eat them while they’re fresh.

Why do shishito peppers turn red?

The peppers will turn red as they mature. They’re usually picked when they’re still green, but you may see some red peppers mixed in with the green ones at the market.

Why are some shishito peppers spicy?

As I mentioned earlier, only about one out of every ten shishito peppers is spicy.

The peppers get their spice from Capsaicin, which is the same compound that makes Jalapenos and other hot peppers spicy.

Capsaicin is an irritant, so if you bite into a hot pepper, you might experience a burning sensation in your mouth.

If you’re sensitive to Capsaicin, it’s best to avoid eating the hot peppers.

Sometimes, a shishito pepper plant contains more capsaicin than others and this makes it spicy.

It can also be because it was growing beside a hot pepper plant and got cross-pollinated.

How to pick the best shishito peppers?

When you’re at the market, look for peppers that are bright green and have a glossy sheen. Avoid peppers that are wrinkled, dull in color, or have brown spots.
