How to Make Mongolian Beef Ramen Stir-Fry Recipe
Step 1: Prepare the Beef
Start by slicing the flank steak into thin pieces against the grain; this is the secret to tenderness. Then toss the beef and cornstarch into a large ziplock bag. Seal the bag and shake it until every piece is evenly coated with that cornstarch, which will give your beef an amazing crispy texture once cooked.
Step 2: Cook the Beef
Heat your vegetable oil in a nonstick skillet over medium-high heat until it’s shimmering. Add the beef in small batches—this prevents crowding and keeps the meat nice and crispy. Cook each batch for 2 to 3 minutes until the beef is beautifully browned. Transfer the cooked beef to a plate and wipe out the skillet to remove excess oil.
Step 3: Sauté the Bell Pepper
Using the same skillet, add the thinly sliced green bell pepper and sauté for 2 to 3 minutes. You want the peppers to soften just slightly but still hold onto a bit of their crispness to add fresh texture to the dish. Then set them aside with the cooked beef.
Step 4: Make the Sauce
In the empty skillet, stir together the sesame oil, low sodium soy sauce, packed brown sugar, minced garlic, chicken broth, and a pinch of red pepper flakes. Simmer the sauce over medium heat and cook until it thickens and reduces by about 25%—this usually takes around 10 minutes. Be mindful not to reduce it too much so you have plenty of savory-sweet sauce to coat the noodles and beef later.
Step 5: Cook the Ramen Noodles
While your sauce is thickening, prepare the ramen noodles following the package instructions. After cooking, drain the noodles thoroughly to keep the stir-fry from becoming soggy.
Step 6: Combine Ingredients
Bring the beef and sautéed bell pepper back into the skillet with the textured, glossy sauce. Toss everything together carefully to ensure every piece is perfectly coated. Finally, add the cooked ramen noodles to the skillet, tossing once again to combine all the components evenly and warm through.
How to Serve Mongolian Beef Ramen Stir-Fry Recipe
Garnishes
Chopped green onions are the classic finishing touch for this dish. Their fresh, oniony brightness cuts through the savory sauce beautifully and adds a splash of vibrant green color that makes the presentation pop. Feel free to sprinkle a few sesame seeds or add a few more red pepper flakes if you like a little extra heat.
Side Dishes
This Mongolian Beef Ramen Stir-Fry Recipe is so rich and satisfying, you don’t need many sides. However, serving it alongside a crisp Asian-style cucumber salad or simple steamed bok choy can add some refreshing contrast. A light miso soup also pairs wonderfully and rounds out the meal.
Creative Ways to Present
For a fun twist, serve this stir-fry in large lettuce cups to turn it into a handheld delight. Alternatively, plating it over steamed jasmine rice instead of ramen can create a comforting bowl reminiscent of traditional Mongolian beef dishes while keeping the unique stir-fry flavors intact.
Make Ahead and Storage
Storing Leftovers
Any leftover Mongolian Beef Ramen Stir-Fry Recipe can be kept in an airtight container in the refrigerator for 3-4 days. The beef stays tender and the noodles retain their texture best when reheated gently.
Freezing
While this dish tastes best fresh, you can freeze leftovers if needed. Store the stir-fry in a freezer-safe container for up to 1 month. To freeze, let the dish cool completely before sealing and freezing to preserve flavor and texture.
Reheating
Reheat refrigerated leftovers in a skillet over medium heat, stirring occasionally until warmed through to prevent the noodles from sticking or becoming mushy. If reheating from frozen, thaw overnight in the fridge first for best results.
FAQs
Can I use a different cut of beef?
Absolutely! While flank steak is ideal for tenderness and flavor, sirloin or skirt steak can also be used. Just be sure to slice thinly against the grain to keep it tender.
Is it necessary to cook the beef in batches?
Yes, cooking the beef in batches prevents overcrowding, which helps achieve a nice sear and keeps the pieces crispy instead of steaming.
Can I substitute ramen noodles with something else?
Definitely! Rice noodles, udon, or even cooked spaghetti can work in a pinch. Just adjust cooking settings as needed for the noodle type.
How spicy is this dish?
This recipe has a mild heat from red pepper flakes, but you can easily adjust the amount to suit your preference or omit it for no spice at all.
Can this recipe be made gluten-free?
Yes, by using gluten-free soy sauce and ensuring the ramen noodles are gluten-free, this dish can be adapted to fit gluten-free diets.

- Do not overcook the noodles; they should be slightly firm as they will cook more when combined with the sauce.
- If preferred, substitute flank steak with sirloin or skirt steak for similar results.
