Delicious Mongolian Beef, quickly stir fried with udon noodles for a quick and easy meal that’s ready in a flash! An easy and delicious weeknight meal.
I love Mongolian Beef and it’s in regular rotation in my kitchen. I usually just cook up the beef and serve it over rice. I’ve recently been enjoying it stir fried with udon noodles and it’s been a delicious, quick and easy dinner that I thought deserved sharing.
If you’re not familiar with Mongolian Beef flavours, it’s best described as sweet and salty, with distinct notes both from the soy sauce and sugar.
Added to the delicious sauce, are easy to use, shelf-stable udon noodles. These udon need no pre-cooking. Simply add them directly to your hot stir fry and cook until warmed through. With just a short marinade time, this dish is ready in a flash and a great weeknight meal!
Beef – I love the “Stir Fry Beef Strips” for this dish, that are often available in the meat counter. If unavailable, pick up any piece of beef steak and cut it into strips yourself. I find cutting the beef when partially frozen makes it easier to cut into thin strips, so if you are taking some beef from the freezer, keep this in mind.
Udon Noodles – this recipe makes use of shelf-stable udon noodles, for a quick and easy meal, though you can use frozen udon as well. I like to soak them in hot water before adding to the pot. If starting with dried udon noodles, you will need to boil them first, before adding to the pot.
You will also need – Green onion, vegetable oil, baking soda, white sugar, cornstarch, soy sauce, rice vinegar, ginger and brown sugar.
If you’re rushed, you can just set the beef to marinade on the counter for 10-15 minutes before stir frying, instead of the longer marinade. A little marinade time is better than none, but longer marinating is of course better, if you have the time.
If you want to start this dish in the morning, you can also pop your beef and marinade into a ziploc bag and let it marinade in the fridge for several hours or all day until dinner time.
Mongolian Beef sauce is, by nature, on the sweet side. It’s kind of the unique feature of this dish. That said, you can certainly dial back the brown sugar in the sauce a bit if it’s too much so for your taste. (Though I always suggest trying it as written first, then going from there).
This is the same basic recipe I use for straight-up Mongolian Beef to serve on it’s own or over rice. So if you enjoy the beef and sauce flavour, you may want to try it that way, as well.

Another excellent dish. I added half red pepper cut thin julienne for added colour.
So glad you enjoyed it, Candy :) Thanks so much!
This was so good and easy to make. I added a can of baby corn because my daughter and I love it. Will be making again soon for sure.
So glad you enjoyed it, Heather :) Thanks so much!
I made this last night for a group friends (6 in total) and it is a good thing I doubled the recipe. I made lot of other good stuff, but this was the first to go. So easy and so delicious and I have to admit, I loved the compliments. Besides the wonderful flavor, it was easy to do all the prep ahead of time, so cooking it up for everyone was easy. Thanks for sharing.
So glad to hear, Dee :) Thanks so much!
This was absolutely delicious!! I doubled the sauce and added a bag of steamed stir fry veggies. Thank you for a new favorite!
So glad you enjoyed it, Rachel :) Thanks so much!
Made this tonight and it was delicious! You have great hints and cooks notes. Thank you!
Thanks so much, Nancy :) Glad you enjoyed it!
Hi Jennifer, I can’t wait to try this. I bought supplies for a chicken udon recipe but tonight I want to use beef. So is it possible to add baby bok choy to this? Or should I hold off on the veggie?
I think bok choy would be great in this one. I say throw it in :) Enjoy!
Tastes better than the one I order at a local resturant! So easy and turned out perfect!
Happy to hear that, Rachel :) Thanks!
I LOVE this recipe! It is so simple, and so flavourful! It turns out perfectly every time I make it and everyone loves it!
Do you think I could substitute the noodles with rice? I live in a very remote community, so udon noodles are not always available unfortunately.
So glad you are enjoying it, Jenna. And yes! I use the same beef with sauce to make a more classic Mongolian beef dinner. I just brown the beef in a skillet, then add the sauce and let it simmer/thicken a bit. Then serve the saucy beef alongside rice and a veg.
Made this last night for a date night with the boyfriend, and oh…my…LORD it’s amazing!
Glad to hear, Montana :) Thanks so much!
Super easy to make and turns out perfectly every time! Thanks for such a tasty recipe!
So glad you are enjoying it, Jenna! Thanks so much :)
Made it tonight. Let it marinade for probably 3-4 hours. Everything was super easy. When I remake this recipe it will probably take 15 mins max. Super cheap too. It was delicious, thank you so much for the recipe.
So glad to hear, Bailey! Thanks so much :)
Have never had Mongolian beef before but couldn’t resist trying this receipe as we’re udon noodle fans. We don’t have beef that often & since the stir-fry cuts were on sale, decided to give this a try. Not much more to say than YUM!!!! Served with French green beans. A definite repeat!
Forgot the 10-star rating!
So glad you enjoyed this! We don’t eat a ton of beef either, but whenever I see the stir fry strip on sale, this is the dish I think of :) You can also make this without the udon. Simply do the beef and sauce and simmer until thickened. Serve with rice and a veg for another great way to enjoy it. Thanks!
I’m going to look for the soft udon noodles as they certainly make this dish come together in no time at all. It looks great.
They do Karen! In my grocers, the shelf-stable udon are in with the dried Asian noodles.
I saw this recipe yesterday, shopped this morning, and made it tonight. It was just delicious. Thanks for a great recipe.
So glad you enjoyed it, Lisa :) Thanks!
Hi Jennifer, this looks so yummy! Can’t wait to make this! Quick question first, should the first ingredient for the sauce say 1 tsp fresh minced ginger? It says garlic, but then garlic is the next ingredient. Thanks !
Yes! Thanks for catching that. Definitely ginger :) Fixed it now.
Made this for dinner last night, it was so delish, totally hit the spot! Way better than takeout!
So glad you enjoyed it, Emma! Thanks :)
Oh wow – look at all those slurpy noodles covered in luscious sauce! Great recipe Jennifer – my kind of meal! I love udon noodles and the sweet sauce sound terrific.
Thanks so much, Tricia :)
Looks so good! I love udon noodles (too much) and would love to try your Mongolian beef version with them – cannot stop looking at this scrumptious dish!
It’s been so long since I’ve had udon noodles so this is perfect timing! So much better on Friday night than take out too :)
Thanks Dawn :)
We’re going away for the weekend, but I’m already looking forward to making this next week! YUM!
Thanks Annie! I think you will enjoy this one ;)
I’ll always choose Udon noodles above rice, love that you swapped them. This looks amazing! Dinner soon!
Thanks Chris and yes, noodles over rice any day :)
I want to reach into my screen and grab a plate of this Jennifer! It looks simply mouthwatering!
Thanks Mary Ann :)
Mongolian beef is definitely a favorite around here too! And I absolutely LOVE udon noodles – they are just so slurp-tastic! Needless to say, I NEED to make this for dinner ASAP! I’m drooling and honestly wish I had this for breakfast!
Thanks Cheyanne and me, too! I’m always look at different ways to enjoy udon :)
