Ingredients You’ll Need

With just a handful of pantry staples and a fresh steak, you’re only a few steps away from the magic of this dish. Each ingredient here serves a purpose, ensuring your 30-Minute Mongolian Beef Recipe turns out deliciously satisfying every time.

Sirloin steak (1½ pounds, 1-inch thick): Look for a steak with good marbling for maximum tenderness and flavor—sirloin is perfect for slices that cook quickly!
Cornstarch (1/3 cup): The secret to a light, crisp coating and the glossy sauce—don’t skip this step!
Canola oil (¼ cup): Neutral, high-heat oil that lets the beef sear beautifully without overpowering the flavors.
Salt (¼ teaspoon): Just a little brings out the boldness of the steak and balances the final dish.
Fresh grated ginger (1 tablespoon): Gives a bright, aromatic pop that is classic in Mongolian beef.
Garlic, minced (4 tablespoons): Don’t be shy with the garlic—it’s a cornerstone of this dish’s deep flavor.
Red pepper flakes or chili oil: Optional, but adds a gentle heat and complexity—adjust to your spice preference.
Reduced sodium tamari sauce or soy sauce (1/3 cup): Tamari keeps it gluten-free but soy sauce works for anyone—provides that craveworthy savory punch.
Water (½ cup): Helps to quickly loosen and blend your sauce for the perfect clingy texture.
Brown sugar (1/3 cup): Balances the savory notes and creates that signature glossy finish.
Scallions, green tops only (8 stalks, cut to 2-inch pieces): A fresh, vibrant ending that adds a pretty garnish and a gentle onion zing.

How to Make 30-Minute Mongolian Beef Recipe

Step 1: Prep and Slice the Steak

Begin by slicing the sirloin steak into thin, ¼-inch strips. For extra tender beef, lay the slices flat on a cutting board, cover them with plastic wrap, and gently pound with a meat mallet until even and flat. This helps your steak stay juicy and cook evenly—a little chef’s secret that makes a big difference in this 30-Minute Mongolian Beef Recipe.

Step 2: Coat the Beef

Transfer the steak slices into a large zip-top bag, add the cornstarch, and zip it shut. Gently massage the bag so every piece of steak gets an even, light coating of cornstarch. This step is crucial; it helps the steak crisp up and ensures your sauce clings just right.

Step 3: Sear the Steak

In a large frying pan, heat canola oil over medium-high. Once shimmering, add the steak in a single layer—work in batches to avoid overcrowding. Sear each piece for about 30 seconds per side. The quick cook keeps the beef meltingly tender! As each batch finishes, set it aside on a plate and immediately sprinkle with salt to lock in flavor.

Step 4: Build the Sauce Base

With the pan still hot, add the grated ginger, minced garlic, and your choice of red pepper flakes or chili oil. Sauté for just 10–15 seconds: you want them fragrant but not browned. This transforms your kitchen into a flavor wonderland and forms the aromatic backbone of the sauce.

Step 5: Simmer the Sauce

Pour in the tamari (or soy sauce), water, and brown sugar, giving everything a good stir. Let the mixture come to a gentle boil, which helps the sugar melt and the flavors meld into that signature sweet-salty-saucy combo.

Step 6: Combine and Thicken

Fold the seared steak back into the bubbling sauce and let it cook, stirring gently, for 20–30 seconds. Thanks to the cornstarch from the beef, the sauce will thicken fast and coat every piece perfectly. This is the very heart of our 30-Minute Mongolian Beef Recipe—saucy, glossy, and loaded with flavor.

Step 7: Add Scallions and Finish

Turn off the heat, toss in the fresh green onions, and stir until just vibrant and wilted. Their freshness balances the richness of the beef, giving the whole dish a pretty pop of color and a gentle bite.

Step 8: Time to Serve!

Pile the hot Mongolian beef over bowls of steaming rice, rice noodles, or tuck it into crisp lettuce wraps. Don’t forget to spoon that luscious sauce over the top—every drop counts!

Garnishes

You can never go wrong with extra garnish! A sprinkle of sliced scallions, a few toasted sesame seeds, or even a drizzle of chili oil over the top will add flavor, crunch, and a finishing touch that turns your 30-Minute Mongolian Beef Recipe into a real showstopper for both the eyes and palate.

Side Dishes

This dish loves to be paired with simple sides that soak up the dreamiest sauce. Fluffy steamed jasmine rice is classic, but rice noodles or even cauliflower rice work beautifully. For something greener, try crisp steamed broccoli or quick wok-tossed snow peas—the freshness balances the richness of the beef.

Creative Ways to Present

Smaller appetizer bowls turn it into a fun party bite, and don’t be shy about experimenting—this 30-Minute Mongolian Beef Recipe loves a little creativity!

Make Ahead and Storage

Storing Leftovers

Leftovers are just as exciting as the first bite! Store any cooled beef and sauce in an airtight container in the fridge for up to 3 days. The flavors deepen overnight, making tomorrow’s lunch just as craveable.

Freezing

This 30-Minute Mongolian Beef Recipe is freezer-friendly. Let it cool completely, then portion into freezer-safe containers. It’ll keep for up to 2 months. When ready to eat, thaw it overnight in the fridge for best texture and flavor.

Reheating

For best results, reheat gently in a skillet over medium heat, adding a splash of water if the sauce needs loosening. A minute or two is all you need to return the sauce to its glossy best and keep the steak tender.

FAQs

Can I use a different cut of beef?

Absolutely! While sirloin is excellent, flank steak or even ribeye work beautifully in the 30-Minute Mongolian Beef Recipe, just slice thin and against the grain for best results.

Is the dish spicy?

The heat level is totally customizable—you can leave out the chili oil or red pepper flakes for a mild dish, or add more if you love a little extra kick.

Can I make it gluten-free?

Yes, simply use reduced sodium tamari instead of soy sauce and double-check your other ingredients. This keeps your 30-Minute Mongolian Beef Recipe completely gluten-free without sacrificing any flavor.

What vegetables go well with this?

Snow peas, bell peppers, or broccoli are classic companions. Toss them into the pan after searing the beef for a heartier meal with even more crunch and color.

Can I make this ahead for meal prep?

Definitely! Portion the beef and rice into separate containers; reheat and add fresh scallions before serving to keep things crisp and vibrant all week long.
