This One Pan Mongolian Beef Noodles is a family-size meal where the noodles cook with everything else in the same pan – no need to cook them separately! Tossed with my favourite Mongolian Lamb sauce and loaded with broccoli , this is a complete dinner in 15 minutes, start to finish.

One Pan Mongolian Beef Noodles with Broccoli
It seems like only yesterday that I first shared a cheeky method where I cook noodles in the same pan as the beef, vegetables and sauce rather than boiling them separately (it was 2019!!!). I was a little skeptical about how it would be received – one pot pasta was widely accepted, but noodles?? That was pretty outlandish back then!
But it was really well received, and I was relieved – firstly, not to be disgracefully admonished (it does happen!), and secondly, because the method does work. Unorthodox, yes. But it doesn’t compromise the end result for convenience, and it’s darn tasty.
Since then, I’ve shared a chicken one, Thai peanut one, mushroom one and chow mein. Today’s sparkling new addition is beefy, flavoured with the tasty sauce from Mongolian Lamb, with bright green broccoli tangled through flavour-coated noodles. It’s a big batch that will serve a family of four, and will take you 15 minutes from start to finish to get on the table.

Ingredients in One-pan Mongolian Beef Noodles
Here’s what you need to make this.
FOR THE NOODLES
This recipe calls for instant noodle cakes, also called 2 minute noodles here in Australia and ramen noodle cakes in the States. These are dried pre-cooked noodles that cook quickly in liquid, and are basically designed to be indestructible!

Instant noodle cakes – As noted above, these are also known as 2 minute noodles (Australia) or instant ramen noodles (US), about 70g/2.5oz each, though you can use noodle cakes up to around 100g/3.5oz. They cook in 2 minutes and are designed to be bulletproof (think, uni student friendly!!) so it’s impossible to stuff this recipe up. I buy plain noodle cakes in sleeves of 10, if yours has seasoning packets, just discard them. Our sauce is so much nicer. 🙂
Other noodles – I can’t think of other types of noodles that will work here as other noodles need to be rinsed after soaking or boiling, to rinse off excess starch so they don’t become gluey in the pan. Whereas instant noodles do not. You could also prepare any other type of noodles per the packet and toss with the sauce (don’t add the water), like you would any other stir fried noodles!
Beef mince (ground beef) – Any fat percentage is fine here, the higher the fat, the juicier and beefier the dish! (The fat contains good beefy flavour). You could also use other proteins – chicken, turkey, pork or lamb. This sauce will suit all of these, though just bear in mind chicken and turkey are leaner so the bits of meat littered throughout the noodles will be a little firmer.
Broccoli – Use one very large head or one and half regular ones. Other vegetables – carrot, cauliflower, capsicum, mushroom, green beans, baby corn or other vegetables that can hold up to 3 – 4 minutes in the pan will work just fine here.
Garlic and onion – Essential flavour base for this noodle dish!
FOR THE SAUCE
Here’s what you need for the sauce. The combination is very specifically chosen for maximum flavour with minimum ingredients! If you don’t have Mirin or can’t consume alcohol, don’t worry, there’s an easy alternative.

Dark soy sauce – This has strong soy flavour and stains the beef and noodle a deep mahogany colour. Carried at most large grocery stores these days. This cannot be substituted with light soy sauce or all-purpose soy sauce as these have less flavour. If you use these instead of dark soy sauce, you will find the flavour lacking. ** UPDATE: I am sad to see some feedback coming through from readers disappointed with the flavour and this is what I suspect has been happening as in most recipes, I say it’s ok to substitute with light or regular soy sauce. So I’ve emphasised more strong that it MUST be dark soy sauce!! **
Hoisin sauce – A thick, sweet-savoury Chinese sauce with lovely Chinese five spice flavour. Key flavouring for the Mongolian Lamb sauce we’re adopting in this recipe! Substitute with oyster sauce plus an extra 1/4 teaspoon Chinese Five Spice.
Mirin – This is a sweet Japanese cooking rice wine that adds depth of flavour and is why this simple sauce is so tasty! Carried at regular grocery stores in Australia these days. For alcohol free, substitute half the water for chicken stock. It’ll give the sauce a bit of depth of flavour you lose by leaving out the mirin.
Chinese Five Spice Powder – A combination of five spices that adds warm, fragrant, distinctly Chinese flavour. easy to find at regular grocery stores these days.
Sesame oil – Use toasted sesame oil (brown, the default carried at Australian grocery stores) not un-toasted which is yellow and doesn’t have as good a sesame flavour.
Water – We add water straight into the pan with the beef and sauce for the noodles to absorb and soften.

How to make One-pan Mongolian Beef Noodles
You need a large deep pan for this recipe – noodles for 4 is a lot to toss! I use a 30cm / 12″ non-stick pan (Pyrolux Ignite Chef Pan, not an affiliate link 🙂 ), pictured in this post. It has a glass lid, stay-cool handles and is deep enough for a double batch of bolognese. One of my favourite pans!
If you don’t have a large deep pan, use a large pot. The smaller surface area is fine – you’ll have deeper sauce for the noodles to cook in, plus nice tall walls for enthusiastic noodle tossing!

Cut the broccoli into fairly small pieces, to ensure they cook through quickly (these noodles cook fast!) and also smaller pieces don’t get in the way as much when squidging the noodle cakes into the liquid to cook.
Don’t forget to use the broccoli stem too! Cut off the tough outer skin, then cut into batons.
Mix the sauce ingredients in a small bowl and set aside.

Cook – Give the onion and garlic a bit of a head start first, then add the beef and cook, breaking it up as you go. Once the beef is no longer red, pour the sauce over and stir until all the beef is nicely coated in the sauce
Add broccoli then stir just until the broccoli is lightly coated in the sauce.

Add water – Pour the water in, give it a stir then let it come up to the simmer.
Break the noodle cakes in half along the direction of the noodles, so the noodle strands stay intact.

Squidge the uncooked noodle cakes into the sauce, burying them into the beef and sauce as best as you can. I find it’s easiest to put them in upright on their side, because we’re trying to put a fair amount of noodles into one pan.
Don’t fret about precision here, like submerging them evenly or rushing. We will be shuffling them around and tossing as they start to soften. These noodles cakes are built to be bombproof.

Start tossing to soften noodles – After you get the last noodle cake in, leave them for 30 seconds to start softening. Then use tongs to flip the noodles over so the other side can start softening. Leave them again for around 30 seconds, then start untangling the noodles and tossing them around so they soften fully. By the time all the sauce in the pan is absorbed by the noodles, the noodles will be fully soft – it takes about 2 to 3 minutes.
And look at that! A big pan of noodles coated in a tasty sauce with beef and broccoli – a complete dinner. Divide between bowls and serve!

So there you go. Dinner on the table in 15 minutes. Really! Once you start cooking it will take 7 to 8 minutes, assuming you’ve got a good heavy based pan and a strong burner. That leaves 7 minutes to chop the broccoli, slice an onion and mix the sauce.
But if you’re trying to watch The Bachelor while FaceTiming five of your besties, refereeing a sibling fight and chasing a Jaffle dragging a pot plant through the house, then you might want to allow a bit of extra time. 🙂 – Nagi x

- Cook beef – Heat the oil in a large, deep 30cm / 12" pan over high heat (or use a large pot). Add the garlic and onion, cook for 30 seconds. Add the beef and cook, breaking it up as you go, until you no longer see red. Add the sauce and cook until the sauce has coated all the beef well.
- Add the broccoli and stir it through to coat I sauce. No need to give it cooking time, I promise it cooks through in the next step!
- Noodles – Add the water. When it starts bubbling, push the noodles in (break in half along direction of noodles so they fit more easily). Leave for 30 seconds, then turn the noodles. Leave another 30 seconds, then start tossing the noodles with two spatulas or tongs until the noodles are softened and there's no sauce left in the pan (2 – 3 minutes). If the noodles need a little longer, just add a bit more water.
- Serve – Divide between bowls and enjoy! A drizzle of sriracha for some heat wouldn't go astray here. 🙂

Life of Jaffle
Jaffle the Shoe Thief. Can someone explain to me why dogs only take one shoe from each pair?? At least if he took both it’d halve the number of shoes taken out of action!!!

Then of course, the shoe rescue part becomes a thrilling game for him as he bolts around the yard, letting me get just close enough to take a swipe at the shoe only to prance off again gleefully…..


….. until he tires out and falls asleep protecting his prize.

A great quick meal!
My sauce didn’t quite thicken up the way it does in the video, that seems happen with all of the stirfry and sauce based recipes I try – what do you think I might be doing wrong?
Needs more sauce and a bit more punch. Added some chilli. Next time will make more sauce (since the water dilutes it) and add more of the hoisin. Otherwise, quick, easy, tasty, and I was pleasantly surprised it worked and the noodles weren’t overcooked.
I was a bit hesitant to try this recipe after seeing more bad reviews than I think I’ve ever seen on a Nagi recipe, but in Nagi we trust, so I took the plunge – and it was delish! So flavourful! Everybody loved it, and it was quick. I am confused why there are so many negative reviews. Def making again!
Bland and tasteless. I think this recipe is missing some ingredients. Hoping this 1 star review flags this for Nagi’s team!
Wasn’t expecting much from such a simple recipe and had some concerns seeing the low rating, but this was seriously good. Even my fussy teenage son went back for seconds. That’s a win in our house.
I nearly ordered takeaway but who can afford it these days, decided to give this a go instead. So glad I did! Even had enough left for lunch tomorrow 😊
Made this for dinner tonight and everyone really enjoyed it. I followed the recipe exactly, and thought the flavour was lovely. The noodles soaked up the sauce really well and the broccoli was cooked just right. I was surprised how quickly it all came together too. Will definitely be making this one again!
Good flavours, easy instructions, minimal cleanup. Added some chilli flakes for extra heat. Will make again.
Firstly, I am a devout Nagi fan! But I didn’t have success with this. I had too much liquid and it didn’t seem to absorb when the noodles were added, and it seemed to dilute the flavour of the sauce.
I saw some really positive reviews so any suggestions why mine failed? I thought I followed this recipe and instructions to a tee and your recipes normally never fail me.
This one was just disappointing. I feel the amount of water diluted the sauce, reducing the flavour to bland. Noodles did not change in colour at all and yes I used dark soya sauce.I followed recipe and haven’t had a Nagi failure before.
I used broccoli, carrot, capsicum and snow peas. Substituted beef stock for half of the water. Delicious

Oh wow, this was a hit!! Clean plates all round and requests to have it again next week. Thank you!
Such an easy tasty midweek dinner. I think the people who have complained about lack of flavour are missing the point- this is a one pot dinner, uses up whatever vege you have available and is ready in 10 mins start to finish. Quicker than ordering takeaway! Also, make sure you use proper dark soy sauce, not regular soy like kikkoman (then it will be pale and lacking) I cooked recipe exactly except mixed in some chilli flakes after serving up for the littlest and it was a hit with all

This recipe has been a hit in our house. Master 6 has decided it’s his favourite meal and asks for it weekly. I love that you can clean out the crisper and add extra veges eg. Capsicum & carrot or just stick to the broccoli. I like a bit more punch, so add chilli crisp to mine, the rest of the family (5 adults + master 6) are happy as is.
Thank you Nagi for another easy meal.
I’m sorry. This was the first time I didn’t live a Nagi recipe.
Not going to lie, after reading the comments wasn’t sure this was going to be good. But it was. Really good. So tasty. I used fresh noodles and only a bit of water, but otherwise stuck to the recipe. Kids loved it. Bit of kewpi mayo to garnish and siracha for the spice lovers. Really quick, really yum! Next time might use peas.
Sooo easy to make and delicious. Mine wasn’t as dark so maybe I used too many noodles. Also added chopped mushrooms and carrot. Definitely adding to our week night favourites. Xxx
Sadly this is the first time my family complained about a ‘nagi’ meal, Like a few others commenting on here, we found it bland and we also added siracha so my son would finish his. Definitely NOT a repeat recipe but hey! 99% of the time your recipes are winners – such is life, Thanks for all the winning recipes even if this is not one of them for us.
