Mongolian Beef Noodles
with bell peppers / snow peas
For maximum flavor and texture, the steak in this noodle stir-fry is coated in cornstarch and shallow-fried in oil before being tossed with noodles and a rich, savory sauce.
Smarts: Put the steak in the freezer for 15 minutes before you start making this meal. Steak is easier to slice thin if it's very cold.

Make
- Heat a wok or skillet with cooking oil over medium heat. When oil is hot, add steak in a single layer. Cook steak, without stirring, until golden brown on one side, 2 to 3 minutes. Use a spatula to flip steak and continue cooking, stirring occasionally, until steak is just cooked through, ~2 minutes more. Transfer steak to a paper towel-lined plate and set aside.
- To remaining oil in the wok, add bell peppers and saute for ~2 minutes to get started cooking.
- Add sauce and bring to a simmer.
- Whisk together second portion of cornstarch and water. Stir into simmering sauce. Simmer for 2 minutes until sauce thickens slightly.
- Add snow peas and cook for 1 minute.
- Add noodles to pan and stir to coat in sauce.
- Remove wok from heat and stir in steak.
- Serve noodles with some extra red pepper flakes or some hot sauce if you’d like. Enjoy!

Very flavorful. After reading the reviews I added more cornstarch to thicken the sauce.

I didn't have snow peas, so I julienned fresh green beans.I added celery, carrots and green onion. I didn't use as much brown sugar. I used a good shake of everything bagel seasoning because I had no sesame oil. Everything else I used and doubled because I had so many vegetables in it. It was yum!
0 HelpfulSo good! I used a snow pea stir fry mix and spaghetti noodles. Next time I'll do lo mein noodles. I did the beef slices in the air fryer! They turned out perfect! Total game changer and so much less messy.
0 HelpfulThis is a deceptively simple meal with a lot of good flavour. Using tofu makes it a low cost meal. I also used Rooster Instant noodles which go really well with the dish
0 HelpfulMade seared flank steak on the side, using the extra sauce (always make extra sauce) as a quick pan-marinade. Both loved it!
