Pin it Flank steak gets marinated in soy and sesame, then quickly stir-fried alongside julienned carrots, bell peppers, and shiitake mushrooms. The dish comes together with chewy sweet potato glass noodles coated in a rich sauce blending gochujang, brown sugar, garlic, and ginger. Baby spinach wilts into the hot noodles, adding fresh color and nutrients. The entire dish cooks in under 30 minutes active time, making it perfect for busy weeknights when you crave something comforting yet vibrant.
Rainy Tuesdays were made for noodles like this. I stumbled upon glass noodles at an Asian market years ago, confused by their translucent appearance, but one bite of that chewy, springy texture had me completely hooked. Now this dish is my go-to when I want something that feels special but comes together in under an hour.
My roommate walked in while I was stir-frying the vegetables and literally stood over the stove asking if it was ready yet. That aroma of sesame, garlic, and caramelizing soy sauce filling the apartment is something nobody can ignore.
Ingredients
- Flank steak or sirloin (400g): Thinly slicing against the grain makes all the difference between tender bites and chewy ones
- Cornstarch: This little coating trick keeps the beef silky and prevents it from toughening up in the high heat
- Sweet potato glass noodles: Their chewy texture is unmatched but rice noodles work in a pinch
- Gochujang: Korean chili paste brings depth and mild heat that regular chili paste just cannot replicate
- Fresh vegetables: Carrots, bell pepper, mushrooms, and spinach add crunch, color, and nutrition
- Sesame oil: Toasted sesame oil at the end is the secret to that restaurant-quality aroma
Instructions
- Marinate the beef:
- Toss sliced beef with soy sauce, cornstarch, and sesame oil, letting it sit while you prep everything else
- Cook the noodles:
- Boil noodles according to package directions, then rinse under cold water to stop cooking and prevent sticking
- Whisk the sauce:
- Combine soy sauce, brown sugar, gochujang, mirin, sesame oil, garlic, ginger, and water until smooth
- Sear the beef:
- Heat oil in a large skillet over medium-high heat and stir-fry beef for 2-3 minutes until just cooked through
- Cook the vegetables:
- Add more oil to the pan and stir-fry carrots, bell pepper, and mushrooms until tender-crisp
- Bring it together:
- Return beef to the pan with noodles, spinach, and sauce, tossing until everything is coated and heated through
- Finish and serve:
- Top with toasted sesame seeds and fresh scallions while piping hot
Pin it This recipe became a dinner party staple after my friend requested it for her birthday. There is something so satisfying about watching people go quiet for that first bite, then immediately ask for the recipe.
Making It Your Own
Once I added extra gochujang because I thought the sauce looked too mild and my husband could not stop drinking water. Now I taste as I go, knowing the heat builds as everything simmers together.
Perfect Pairings
Cold barley tea cuts through the richness beautifully, though a cold lager works just as well. On especially hungry nights I serve it with kimchi fried rice on the side.
Make Ahead Magic
The sauce keeps well in the fridge for up to a week, and I often double it to have ready-to-go stir-fry sauce for busy weeknights. Just slice the beef and vegetables the night before for an even faster dinner.
- Package leftovers in portions for an office lunch that reheats perfectly
- Add extra vegetables like snap peas or bean sprouts for more crunch
- If the noodles seem dry, splash in a little water or more sauce when reheating

Recipe FAQs
- → What type of noodles work best?
-
Sweet potato glass noodles (dangmyeon) are traditional for their chewy texture, but rice noodles or even udon work well as substitutes.
- → Can I make this dish less spicy?
-
Reduce the gochujang to half or omit it entirely. The dish will still have plenty of flavor from soy sauce, garlic, ginger, and sesame.
- → How do I prevent the beef from getting tough?
-
Slice the beef thinly against the grain, marinate briefly with cornstarch, and stir-fry quickly over high heat just until cooked through.
- → What vegetables can I substitute?
-
Bok choy, snap peas, zucchini, or cabbage work beautifully. Adjust cooking times so softer vegetables don't overcook.
- → Can I prepare this ahead?
-
Prep all ingredients and make the sauce in advance. Cook everything just before serving, as noodles absorb sauce quickly and may become mushy.
- → Is this dish gluten-free?
-
It can be with tamari instead of soy sauce and certified gluten-free noodles. Always check labels on gochujang and other condiments.
