Mongolian Beef Noodles
with bell peppers / snow peas

Active: 40 min Total: 40 min
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.


Mongolian Beef Noodles:
  • Steak, flank - 1 lb , thinly sliced against the grain (sub any variety of steak)
  • Bell peppers, green - 1 , thinly sliced
  • Pasta, gluten-free spaghetti - 8 oz
  • Salt - 1/2 tsp
  • Black pepper - 1/4 tsp
  • Cornstarch - 2 Tbsp + 1 Tbsp
  • Oil, cooking - 3 Tbsp
  • Water - 1 Tbsp
  • Snow peas, fresh or frozen - 10 oz (sub snap peas)
  • Hot sauce (opt) - for serving
Mongolian Stir-fry Sauce:
  • Garlic - 4 cloves , chopped
  • Stock, any type - 1 1/4 cup
  • Tamari - 1/3 cup
  • Brown sugar - 3 Tbsp
  • Oil, toasted sesame - 2 tsp
  • Red pepper flakes (opt) - 1/2 tsp


  1. Chill steak - Place steak in the freezer for 15 minutes. (This will make it much easier to slice thinly.)
  2. Bell peppers / Garlic - Prep as directed. Store separately. (Can be done up to 5 days ahead)
  3. Make sauce - Combine garlic, stock, Tamari, brown sugar, toasted sesame oil, and red pepper flakes. (Can be done up to 5 days ahead)
  4. Cook pasta - Cook pasta according to package instructions. If making ahead, toss with some oil to help prevent sticking. (Can be done up to 2 days ahead)
  5. Slice steak - Thinly slice steak against the grain. Toss with salt and pepper and then toss with first portion of cornstarch.


  1. 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.
  2. To remaining oil in the wok, add bell peppers and saute for ~2 minutes to get started cooking.
  3. Add sauce and bring to a simmer.
  4. Whisk together second portion of cornstarch and water. Stir into simmering sauce. Simmer for 2 minutes until sauce thickens slightly.
  5. Add snow peas and cook for 1 minute.
  6. Add noodles to pan and stir to coat in sauce.
  7. Remove wok from heat and stir in steak.
  8. Serve noodles with some extra red pepper flakes or some hot sauce if you’d like. Enjoy!
