Are you looking for a quick and flavorful stir-fry? You’ll want to make this Korean Chili Pepper and Potato Stir-Fry today! It’s easy-to-make, flavorful with a spicy kick that is perfect with a bowl of rice.

Potato is such a versatile ingredient. It tastes good in any form and is especially delicious when they are slightly pan-fried or roasted. When it comes to stir-fry at home, I like to add crunchy ingredients to get the mouthfeel, and this time I used Korean Pepper. I like these peppers as they are milder compared to serranos with a crunchy texture. They are normally available at Korean grocery stores like HMart.

This Korean Chili Pepper and Potato Stir-Fry, 青椒炒土豆 (Qīngjiāo chǎo tǔdòu) is such a simple and quick recipe so you can turn it into a meal in less than 30 minutes. If you like a more spicy version of this dish, feel free to use jalapeños, Shishito peppers, or other peppers of your choice.
Korean Chili Pepper and Potato Stir-Fry variation
- Potato – I used Russet but other potato variety works here such as golden, red, or sweet potato.
- Korean Pepper – As mentioned above, I love the chili’s mild taste plus it has a great crunchy texture that goes so well with the pan-fried potatoes. Other options include jalapeños, Shishito peppers, bell peppers, or red chili peppers.

How to make Korean Chili Pepper and Potato Stir-Fry
First, clean and cut potatoes into thick strips. Soak the potato strips in water to remove starch. Then, drain and wipe them with a clean paper towel. Set aside.

To prepare the chili peppers, once they are cleaned, I removed the seeds saving only the green parts for the stir-fry. This helps reduce the spicy heat.

Heat a non-stick pan with oil, then pan-fry potatoes until golden brown. Dish out and drain them on a paper towel to remove excess oil.
Using the same pan with the remaining oil, cook mashed tofu until golden brown, then add in the garlic and chili (if using). Sauté until garlic is aromatic. Skip garlic for an allium-free dish.

Add in the chili peppers, give it a quick toss, then add the cooked potatoes and seasoning.
Toss all ingredients until well-combined and stir in some cornstarch slurry to finish up the meal. How easy is that? Serve warm!
