Ingredients You’ll Need

These ingredients come together perfectly to balance hearty beef, crisp veggies, and flavorful noodles. When you pick your flank steak, make sure it’s sliced thinly across the grain for maximum tenderness.

• Canola oil: Great for high-heat cooking without overpowering other flavors.
• Flank steak: Thinly sliced for quick cooking and tender results.
• Sesame oil: Adds a toasty, nutty aroma that’s essential in Asian-inspired dishes.
• Red onion: Brings a mild sweetness and crunch to the stir-fry.
• Orange bell pepper: Offers vibrant color and a subtle fruity taste.
• Broccoli florets: Provide texture and a healthy dose of greens.
• Minced garlic: For that savory kick that livens up the sauce.
• Red pepper flakes: Just the right amount of heat to keep things interesting.
• Brown sugar: Balances the salty and spicy notes with a touch of sweetness.
• Soy sauce: The salty backbone that ties the whole dish together.
• Water: Helps create a simmering sauce that coats everything well.
• Rice vinegar: Adds a subtle tang to brighten up the flavors.
• Stir-fry soba noodles: Makes this a complete meal with a lovely chewy texture.

Variations

I love customizing this Skinny Mongolian Beef Noodles Recipe depending on what’s in my fridge or who I’m cooking for. Feel free to add or swap veggies and adjust the spice level to make it your own!

• Make it spicier: I sometimes add a dash of sriracha or increase the red pepper flakes; my family enjoys the extra heat, but you can tone it down for little ones.
• Vegetarian twist: Swap the flank steak with sliced mushrooms or tofu—both soak up the sauce beautifully in my experience.
• Different noodles: If soba isn’t your favorite, try rice noodles or even whole wheat spaghetti for a fun texture change.
• Extra veggies: Adding snap peas or shredded carrots can give it more crunch and color. I do this when I want a veggie boost.

How to Make Skinny Mongolian Beef Noodles Recipe

Step 1: Brown the Steak Just Right

Start by heating canola oil in a large skillet or stir-fry pan over medium-high heat. Season your thinly sliced flank steak with salt and pepper, then cook it for about 5-6 minutes until you see a nice brown crust forming. Don’t overcrowd the pan—this helps the steak brown rather than steam. Once browned, remove it from the pan and set it aside; you’ll finish cooking it later.

Step 2: Stir-Fry the Veggies for That Perfect Bite

Next, add sesame oil to your pan, then toss in the diced red onion, orange bell pepper, and broccoli florets. Stir-fry these for around 5 minutes until the veggies are bright and just tender, but still have a bit of crunch. This texture contrast is what makes this dish so enjoyable to eat. Keep stirring to prevent burning—using a large pan helps.

Step 3: Bring the Sauce to Life

Add minced garlic, red pepper flakes, brown sugar, soy sauce, water, and rice vinegar to the pan with your veggies. Stir everything well and let it cook for 3-4 minutes so the flavors meld and the sauce thickens slightly. You’ll notice the kitchen instantly smells amazing—this is the magic moment where the dish really comes alive.

Step 4: Combine Steak & Noodles for the Finish

Return the browned flank steak to the pan and add the stir-fry soba noodles right on top. Stir everything gently but thoroughly to make sure the noodles are coated evenly and the steak heats through. Let it cook together for about 5 minutes. You want the sauce to cling to each strand of noodle and every bite of beef.

Finally, sprinkle with toasted sesame seeds before serving—I promise this little garnish adds an irresistible nutty crunch!

How to Serve Skinny Mongolian Beef Noodles Recipe

Garnishes

Aside from sesame seeds, I often like to add chopped green onions or fresh cilantro to brighten the dish visually and flavor-wise. A squeeze of fresh lime on top can also add a refreshing zing, which balances the sweet and savory sauce nicely.

Side Dishes

I usually serve this Skinny Mongolian Beef Noodles Recipe alongside simple steamed dumplings or a crisp Asian slaw. A bowl of miso soup on the side makes the meal feel more complete and comforting during cooler evenings.

Creative Ways to Present

For special occasions, I like to plate the noodles in a shallow bowl topped with a perfectly cooked soft-boiled egg and a sprinkle of toasted sesame seeds. Using bamboo steamers as serving bowls or adding edible flowers elevates the presentation and surprises guests with a restaurant-style finish.

Make Ahead and Storage

Storing Leftovers

I store leftovers of Skinny Mongolian Beef Noodles Recipe in an airtight container in the fridge for up to 3 days. To keep the noodles from sticking together, I drizzle a tiny bit of sesame oil before sealing the container.

Freezing

Freezing isn’t my favorite for this dish because the noodles can get mushy, but if you need to freeze it, keep beef and sauce separate from the noodles in freezer bags. Thaw overnight in the fridge and reheat gently to preserve the texture the best you can.

Reheating

I recommend reheating leftovers on the stove over medium heat, stirring occasionally so the sauce doesn’t stick or burn. Adding a splash of water or broth helps loosen the sauce and refresh the noodles. Microwave works in a pinch, but the stovetop method keeps the best texture.
