What is miso?
Miso is a traditional Japanese seasoning made from fermented soybeans, salt, and koji starter (a type of mold).
It has a rich savory, umami flavor and comes in different varieties, ranging from white miso to red miso.
White miso is more mild and sweet, compared to red miso which is more deeply flavored and robust.
Miso is used in soups, marinades, and sauces, and adds depth and complexity to many dishes. Try it in Miso Mushroom Focaccia or Miso Tahini Green Beans.
What is miso chili oil?
Miso chili oil is a fusion condiment that blends the deep umami flavor of Japanese miso paste with the fiery heat of fresh red chilies, drawing inspiration from traditional Chinese chili oil.
Unlike traditional chili oil, the miso paste thickens the oil slightly, giving it a more substantial texture and added savory, umami flavor.
It’s a great way to enhance simple dishes with many layers of flavor.
Different types of chili oils
Vietnamese sa tế: a chili sauce similar to chili oil, but includes lemongrass, garlic, galangal, fish sauce and sometimes dried shrimp for extra umami flavor. Used in Bun Bo Hue.
Japanese la-yu: a mild, sesame oil-based chili oil that is used to flavor ramen noodles and gyoza potstickers.
Chinese chili oil: a fragrant oil infused with Sichuan peppercorns, dried chilies and spices such as star anise.
Chili crisp: a flavored oil with crispy, crunchy bits of fried garlic, onions, chili flakes and sesame seeds.
Ingredients you'll need

- fresh garlic: finely chopped
- Japanese red miso paste: adds savory, salty flavor

How to make miso chili oil
Combine the red chilis and peanut oil in high-powered blender and blend until smooth.

Pour the blended chilies into a cold wok.
Turn on high heat, and stir fry the chili oil constantly until all moisture has evaporated, about 25 minutes, or until there is not much steam coming out of the wok.
Add in the garlic and continue to stir fry until the garlic turns crispy and golden, about 10 minutes.

Next, add in miso paste and continue stir fry for a few more minutes and until it turns into a darker color.
Add in the sugar and fry for another 2 minutes, until dissolved.
Then add in vinegar and continue stirring for 2 more minutes.
Finally, add in the sesame oil and sesame seeds, and cook for one more minute.
Carefully fill the chili oil into two (2) 1-cup sterilized mason jars, and seal with a canning lid.

How to use miso chili oil
Drizzle over rice or noodles: adding a spoonful elevates any bowl of steamed rice or bowl of noodles.
Enhance stir-fries: use it to add a rich, spicy kick to vegetables, tofu, or stir-fry with noodles (mee goreng).
Dumpling sauce: mix the chili oil with soy sauce and black vinegar for a quick and flavorful dipping sauce to serve with pork dumplings, chili oil wontons, or shrimp dumplings.
Marinate proteins: brush onto grilled meats, fish, or seafood for a punch of flavor.
Infuse doughs: add kicked up flavor to breads and buns or pizza, with a drizzle of chili oil. Try my Chili Oil & Chinese Sausage Focaccia.

How to store
Store unopened miso chili oil in a dark, cool location.
Once opened, place the chili oil in the fridge for up to 6 months.
Expert tips
*Note that the cooking process of the chilies will go through various phases (see photos above).
Use good-quality miso: adjust by using red miso or white miso paste for different depths of flavor.
Adjust the spice level: for more mala numbing flavor, try adding Sichuan peppercorns or use different chilies for variation.
Add more oil: if you find the chili oil too thick for your liking, add a little more oil after finishing cooking, but before adding to the jars.
Store properly: keep in a sterile, airtight jar in the fridge to maintain freshness.
