What are Chili Crisp and Gochujang Anyway?
To elevate this weeknight udon stir fry, I add a touch of chili crisp and gochujang, two key ingredients that bring extra depth and a flavorful kick. Not sure what they are? Let’s dive in!
Chili Crisp
Chili crisp is a popular Chinese condiment made from crispy fried garlic, onions, and chili peppers, all suspended in oil. It adds a savory, spicy, and umami-rich flavor to any dish. The combination of crunchy bits and the flavorful oil makes it an excellent addition to stir-fries, noodles, and even dumplings. In this udon stir fry recipe, chili crisp enhances the overall flavor with a delicious, spicy kick. You can find chili crisp in the cultural food aisles of most grocery stores or online, and it’s perfect for adding an extra depth of flavor to your cooking.
Gochujang
Gochujang is a traditional Korean fermented chili paste made from chili powder, fermented soybeans, and salt. It has a perfect balance of spicy, sweet, and savory, which makes it a versatile ingredient in a variety of dishes, from bibimbap to marinades. In this udon stir fry recipe, gochujang adds a deeper layer of heat and a touch of sweetness that complements the other ingredients. It’s a great way to bring authentic Korean flavors to your stir-fry or any other Asian-inspired dish. If you haven’t tried gochujang yet, it’s definitely worth seeking out—its bold flavor will elevate your cooking.

FAQS
Can I use dried or frozen udon noodles instead of fresh?
Yes! While homemade noodles have a chewier bite, both dried and frozen udon noodles work beautifully in this stir-fry. Just follow the package instructions and avoid overcooking so they stay springy.
What is chili crisp? What is gochujang?
These flavorful condiments bring the heat and umami. For a full breakdown, head to the What Is Chili Crisp and Gochujang section above.
Can I make this stir-fry vegetarian or vegan?
Absolutely. Use smoked tofu instead of chicken, and be sure your chili crisp and gochujang are plant-based (most are, but check the labels). The sauce and veggies deliver plenty of flavor on their own.
What protein works best in this recipe?
We often use chicken or smoked tofu, but thin-sliced beef, shrimp, or tempeh also work well. Just cook your protein first so it stays tender and well-seasoned.
Can I prep anything ahead of time?
Yes! You can mix the sauce and chop your vegetables ahead of time. If you’re making homemade udon, the dough can rest in the fridge for up to a day. This makes weeknight cooking even faster.
