Step-by-Step Instructions
1. Prepare the Beef
Pat the beef dry with paper towels.
Slice it thinly against the grain and place it in a bowl.
Add cornstarch and black pepper and toss until the beef is lightly coated.
This helps create a tender texture and allows the sauce to cling beautifully to the meat.
2. Brown the Beef
Heat vegetable oil in a large deep skillet or Dutch oven over medium-high heat.
Add the beef in a single layer.
Cook for 2–3 minutes per side, until browned around the edges.
Transfer the beef to a plate and set aside.
3. Prepare the Mongolian Sauce
Reduce the heat to medium.
Add garlic and ginger to the same pan and cook for about 30 seconds until fragrant.
Pour in soy sauce, brown sugar, water, hoisin sauce, rice vinegar, sesame oil, and red pepper flakes if using.
Stir until the sugar dissolves.
4. Cook the Noodles
Pour the beef broth into the skillet and bring the mixture to a gentle boil.
Add the noodles.
Cook for approximately 8–10 minutes, stirring frequently, until the noodles are tender and most of the liquid has been absorbed.
Add a small splash of broth or water if the noodles need more liquid.
5. Return the Beef
Add the browned beef back to the skillet.
Toss everything together until the noodles and beef are thoroughly coated in the glossy Mongolian sauce.
Cook for another 2–3 minutes.
6. Add the Greens
Stir in the spinach or bok choy.
Cook for 1–2 minutes, just until wilted.
Add the sliced green onions and toss gently.
7. Serve
Divide the Mongolian beef noodles among serving bowls.
Sprinkle with sesame seeds and additional green onions.
Serve immediately while the noodles are hot and saucy.
Cooking Tips
- Slice the beef against the grain for the most tender texture.
- Do not overcrowd the pan when browning the beef.
- Use low-sodium soy sauce so the finished dish does not become overly salty.
- Stir the noodles frequently while cooking so they do not stick together.
- Add extra broth gradually if the sauce becomes too thick before the noodles are tender.
Serving Suggestions
Serve these one-pot Mongolian beef noodles with:
- Steamed broccoli
- Asian cucumber salad
- Stir-fried vegetables
- Vegetable spring rolls
- Sesame green beans
Storage
Store leftover Mongolian beef noodles in an airtight container in the refrigerator for up to 3 days.
Reheat gently in a skillet or microwave with a splash of beef broth or water to loosen the sauce and restore the noodles’ texture.
Leftover Ideas
- Add extra vegetables and turn leftovers into a quick stir-fry.
- Serve the beef and noodles inside lettuce cups.
- Add a fried egg on top for an easy next-day meal.
