Ingredients

For the Beef and Sauce

• 1 lb flank steak or sirloin, thinly sliced against the grain
• 2 tbsp vegetable oil
• 3 cloves garlic, minced
• 1 tsp fresh ginger, grated
• ¼ cup low-sodium soy sauce
• 2 tbsp hoisin sauce
• 2 tbsp brown sugar
• ½ cup beef broth

For the Noodles

• 8 oz egg noodles or rice noodles
• 2 green onions, sliced
• 1 tsp sesame oil

Optional Garnishes

• Sesame seeds
• Red pepper flakes

How To Make It

1. Cook the noodles: Bring a large pot of salted water to a boil and cook the noodles according to package instructions. Drain and toss with sesame oil to prevent sticking.
2. Sear the beef: Heat vegetable oil in a large skillet or wok over medium-high heat. Add the sliced beef in a single layer and sear for 1–2 minutes per side until browned but not fully cooked through. Remove and set aside.
3. Make the sauce: In the same pan, reduce heat to medium, then add garlic and ginger. Sauté until fragrant, about 30 seconds. Stir in soy sauce, hoisin, brown sugar, and beef broth. Bring to a simmer.
4. Combine beef and sauce: Return the beef to the skillet. Cook, tossing frequently, until the sauce thickens slightly and the beef is fully coated, about 2–3 minutes.
5. Assemble the noodle bowl: Divide noodles between bowls and top with the saucy beef. Sprinkle with sliced green onions, sesame seeds, and red pepper flakes if desired.

Tips for Perfect Mongolian Beef Noodles

• Slice the beef thinly and against the grain for maximum tenderness.
• Avoid overcrowding the pan when searing; cook in batches if needed to get a nice browning.
• The sauce thickens as it simmers; keep an eye on it and reduce quickly if it becomes too thin.
• Toss noodles with sesame oil immediately after draining to prevent clumping.
• For a shortcut, use pre-sliced stir-fry beef or leftover roasted beef.

Variations and Substitutions

• Protein swaps: Ground beef noodles work well for a quicker, budget-friendly version. Chicken or tofu are excellent alternatives for a different twist.
• Noodle swaps: Use udon, soba, or rice noodles depending on your preference.
• Sauce tweaks: For extra depth, add a splash of oyster sauce or a pinch of chili flakes.
• Veggie boost: Stir in snap peas, bell peppers, or broccoli for added color and nutrition.

Can I make this ahead of time?

Yes, you can prepare the sauce and slice the beef up to a day in advance. Cook noodles just before serving for the best texture.

Can I freeze Mongolian beef noodles?

It’s best to freeze the beef and sauce separately from the noodles. Noodles can become mushy when thawed and reheated.

What if I don’t have hoisin sauce?

You can substitute with a mix of soy sauce, brown sugar, and a touch of ketchup or miso paste for similar sweetness and depth.

Can I use ground beef instead of sliced steak?

Absolutely. Brown the ground beef first, then proceed with the sauce. It makes a quicker, kid-friendly version of the dish.

How can I make it spicier?

Add chili garlic sauce or a sprinkle of red pepper flakes while cooking the sauce. Adjust to taste for a gentle or fiery kick.
