Ingredients You’ll Need

Just a handful of simple, everyday ingredients transform into something seriously special with Skinny Mongolian Beef Noodles. Each one plays a starring role—the bold beef, the vibrant veggies, the slurp-worthy noodles, and the irresistible sweet-salty sauce all come together for that takeout-inspired magic.

• Canola Oil: Helps deliver that golden sear on the beef without adding extra heaviness—go for a neutral oil so the flavors shine.
• Flank Steak: Sliced across the grain for tender, melt-in-your-mouth strips; a lean cut that works beautifully for quick stir-frying.
• Sesame Oil: Adds a hint of nutty depth that’s essential for real stir fry flavor—just a little does wonders!
• Red Onion: Brings a gentle sweetness and a lovely pop of color to the finished dish.
• Orange Bell Pepper: Slices of crisp, sweet bell pepper brighten every bite and amp up the veggie factor.
• Broccoli Florets: The ultimate “eat your veggies” star—tender yet crisp, and perfect for soaking up sauce.
• Minced Garlic: For bold, aromatic flavor that infuses every layer of the dish.
• Red Pepper Flakes: Adds gentle heat—adjust more or less depending on your spice preference!
• Brown Sugar: Lends that signature Mongolian beef sweetness while balancing the savory notes.
• Soy Sauce: Deep, umami-rich flavor forms the backbone of the sauce—use low-sodium if desired.
• Water: Keeps the sauce just the right consistency to coat everything evenly.
• Rice Vinegar: A touch of acidity that brightens and balances the sweet and salty components.
• Stir-Fry Soba Noodles: Quick-cooking, wonderfully chewy Japanese noodles that make this so hearty and fun to eat.
• Sesame Seeds (Garnish): That final, classic touch—adds a fun bit of crunch and visual flair!

Variations

One of the best things about Skinny Mongolian Beef Noodles is how delightfully flexible it is. Whether you’re catering to special diets or just riffing with what’s in your fridge, there are so many fun ways to make this recipe your own without compromising on flavor.

• Swap the Protein: Try thinly sliced chicken breast or tofu for a lighter or vegetarian spin—just adjust the cooking time accordingly!
• Change Up the Veggies: Snap peas, mushrooms, baby corn, or snow peas are all fair game if you want to clear out your produce drawer.
• Go Gluten-Free: Use tamari in place of soy sauce and choose gluten-free rice noodles or glass noodles for an allergy-friendly option.
• Level Up the Heat: Love spice? Add extra red pepper flakes, a squeeze of Sriracha, or toss in fresh chili for a fiery twist.
• Low-Carb Version: Swap the soba noodles for spiralized zucchini or shirataki noodles for a lighter, lower-carb meal.

How to Make Skinny Mongolian Beef Noodles

Step 1: Sear the Steak

Start by heating canola oil in a large skillet or wok over medium-high heat. Generously season your thinly sliced flank steak with salt and pepper, then add it to the hot pan. Cook it for 5–6 minutes, tossing occasionally, until the edges are browned. This step locks in the juices and brings out the steak’s flavor—then, just set the steak aside on a plate while you move on to your veggies.

Step 2: Stir-Fry the Veggies

To the same pan, drizzle in your sesame oil, then toss in the red onion, bell pepper slices, and broccoli florets. You’ll want to stir-fry this colorful combo for about 5 minutes, just until the broccoli turns bright green and everything is crisp-tender. The goal is to keep some bite for texture and vibrant color.

Step 3: Build the Sauce

Add garlic and red pepper flakes to the veggies, then sprinkle in the brown sugar. Pour in the soy sauce, water, and rice vinegar. Stir well and let everything simmer, bubbling gently, for 3–4 minutes—this gives the sauce time to thicken slightly and infuse all that wonderful flavor throughout the veggies.

Step 4: Bring It All Together

It’s time to reunite the beef and introduce those quick-cooking soba noodles. Add the cooked steak back to the pan along with the soba noodles. Toss vigorously to coat everything in that glossy Mongolian sauce, then cook for another 5 minutes. Everything should be coated, saucy, and piping hot!

Step 5: Finish & Serve

Slide your Skinny Mongolian Beef Noodles onto plates or bowls, then sprinkle liberally with sesame seeds. You’ll get one last pop of crunch and a picture-perfect finish for your masterpiece. Now’s the moment to dig in and savor all that flavor!

How to Serve Skinny Mongolian Beef Noodles

Garnishes

Finish your Skinny Mongolian Beef Noodles with a generous sprinkle of sesame seeds and, if you’d like, some finely sliced green onions or extra red pepper flakes for a bit more drama. A squeeze of fresh lime over the top can also bring a pop of brightness that’s absolutely irresistible.

Side Dishes

These noodles are a star all on their own, but for a bigger spread, consider starting with a simple cucumber salad, a bowl of miso soup, or even some homemade pickled veggies for crunch and contrast. A side of steamed edamame is also a fantastic, protein-boosting partner.

Creative Ways to Present

Serve the noodles in big, shallow bowls for a modern look, or go classic and pile them high on a family-style platter. For fun, divide into individual takeout boxes for a playful, restaurant-inspired vibe—bonus points for eating with chopsticks! A nest of noodles with the veggies and beef artfully arranged on top is always a showstopper too.

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have leftovers, store your Skinny Mongolian Beef Noodles in an airtight container in the fridge. They’ll keep nicely for up to 3 days, making them a fabulous make-ahead meal for busy lunches or nights when you need a quick dinner fix.

Freezing

While the noodles themselves tend to lose a bit of texture after freezing, the beef, sauce, and veggies freeze well. For best results, freeze the beef and veggie mixture separately from cooked noodles in zip-top bags. Thaw overnight and toss with freshly made soba for the perfect revive!

Reheating

To bring leftovers back to life, reheat gently in a skillet over medium heat with a splash of water or broth to loosen up the sauce. The microwave works in a pinch too—just cover loosely and reheat in bursts, stirring in between, until everything is steaming hot and ready to enjoy again.
