Homemade PF Chang’s Mongolian Beef

PF Chang’s Mongolian Beef is one of the chain’s most recognizable dishes — thinly sliced flank steak coated in a dark, lacquered glaze that hits every note at once: salty, sweet, garlicky, and just a little smoky from the high-heat wok. The sauce clings to each piece of beef in a glossy mahogany coat, and a generous pile of green onions cuts through the richness with a fresh, sharp finish.

Making it at home is more achievable than it looks. The restaurant’s signature texture comes from a two-step process — coating the beef in cornstarch and frying it before tossing it in sauce — and once you understand that, the rest is just pantry ingredients and about fifteen minutes of active cooking. The result is genuinely close to the original, and it costs a fraction of the price.

About PF Chang’s’s Mongolian Beef

Despite the name, Mongolian Beef has no real connection to Mongolian cuisine. It’s a Chinese-American creation built around a sauce of soy sauce, brown sugar, garlic, and ginger — bold, simple flavors that reduce into something complex and deeply savory. PF Chang’s version leans noticeably sweet, with a thick glaze and a clean finish that keeps the dish from feeling heavy.

The technique is what separates good Mongolian Beef from great. Flank steak is dusted in cornstarch and fried briefly in hot oil, which builds a lightly crispy crust on each slice. That crust is the key — it gives the sauce something to grip rather than pool around, and it keeps the beef from turning limp during the final wok toss. The whole sequence from fry to plate takes under two minutes once you start.

How Much Does It Cost to Make PF Chang’s’s Mongolian Beef at Home?

A full batch makes 4 servings for about $2.12 in ingredients — roughly $0.53 per serving. Ordering the equivalent at PF Chang’s runs around $19.00, so making it yourself saves about $16.88 (89%). Those numbers come from current US average grocery prices (US BLS Average Price Data, May 2026), not estimates — the per-ingredient breakdown is in the table above. The savings are this large because you’re buying staple ingredients in bulk instead of paying for a prepared, served dish, and a single batch stretches across many servings.

Why Make It at Home?

At nearly $20 a plate, PF Chang’s Mongolian Beef is one of the pricier items on the menu, and the portion is modest. Making it at home for four people costs well under half that, and you get to control things the restaurant doesn’t let you adjust — the sweetness level, the sodium, the ratio of sauce to beef, and the amount of green onions, which restaurants tend to use sparingly but which are genuinely half the dish.

Ingredients for Copycat PF Chang’s Mongolian Beef

Here’s the full ingredients list you’ll need to make PF Chang’s Mongolian Beef at home:

• 1.5 lb flank steak, sliced 1/4 inch thin against the grain
• 0.33 cup cornstarch, divided
• 0.5 cup vegetable oil, for frying
• 6 each green onions, cut into 2-inch pieces
• 4 clove garlic, minced
• 1 tsp fresh ginger, grated
• 0.5 cup low-sodium soy sauce
• 0.5 cup dark brown sugar, packed
• 2 tbsp hoisin sauce
• 1 tsp toasted sesame oil
• 0.25 cup water
• 2 cup jasmine rice, for serving

A few ingredient notes:

• Flank steak is the right cut here — lean, flavorful, and tender when sliced thin against the grain. Freeze it for 20 minutes before slicing to firm it up enough for clean, even cuts. Skirt steak is a workable substitute if flank isn’t available.
• Low-sodium soy sauce is not optional. The sauce reduces significantly during cooking, concentrating the salt. Regular soy sauce will make the finished dish nearly inedibly salty without any other changes to the recipe.
• Dark brown sugar gives the sauce a deeper, more molasses-forward flavor that’s closer to the restaurant version. Light brown sugar works too but produces a slightly thinner, less complex glaze.

How to Make PF Chang’s Mongolian Beef at Home

Prep: 20 min · Cook: 15 min · Makes: 4 servings

1. 1. Slice the flank steak as thin as you can manage — about 1/4 inch — cutting directly across the grain. Toss the slices with 4 tablespoons of cornstarch until evenly coated. Let the beef rest on the cutting board for 10 minutes while you prepare the sauce.
2. 2. In a small saucepan, combine the soy sauce, brown sugar, water, hoisin sauce, minced garlic, and grated ginger. Bring to a simmer over medium heat, stirring until the sugar fully dissolves. Stir the remaining 1 teaspoon cornstarch into 1 tablespoon of cold water, then whisk it into the sauce. Simmer for 2 minutes until the sauce thickens enough to coat a spoon. Remove from heat.
3. 3. Heat the vegetable oil in a wok or large heavy skillet over high heat until shimmering and nearly smoking, about 375°F. Test with a single piece of beef — it should sizzle hard on contact.
4. 4. Fry the beef in two batches to avoid crowding. Lay the slices in a single layer and cook for 60 to 90 seconds per side until the edges are crispy and browned. Remove to a paper towel-lined plate and repeat with the second batch.
5. 5. Pour off all but about 1 tablespoon of oil from the wok. Return to high heat. Add the white parts of the green onions and stir-fry for 30 seconds until just softened.
6. 6. Add the fried beef back to the wok and pour the sauce over everything. Toss quickly and constantly for 30 to 45 seconds until the sauce thickens and lacquers every piece of beef. If it seems thin, let it bubble for another 20 to 30 seconds.
7. 7. Add the green tops of the scallions, toss once more, and remove from heat immediately. Serve over steamed jasmine rice.

Tips for the Best Results

• Let the oil get genuinely hot before adding the beef — the wok should be almost smoking. Cool oil means steamed, gray beef instead of crispy-edged slices.
• Prepare the sauce completely before you start frying. The final wok toss moves fast, and there’s no time to stir a sauce while also managing the beef.
• Separate the green onion whites from the greens before you start. The whites go in early for flavor; the greens go in at the very end for freshness and color.
• If the sauce is thicker than you want after sitting, whisk in a tablespoon of warm water. It should be pourable but thick enough to coat the back of a spoon.

Common Mistakes to Avoid

• Crowding the pan during frying. Too much beef drops the oil temperature instantly and the beef steams rather than crisps. Two batches minimum.
• Overcooking the beef. Flank steak sliced 1/4 inch thick is done in under 2 minutes total in hot oil. Going longer makes it tough and chewy regardless of how tender the cut was raw.
• Letting the beef sit in the sauce too long. Toss quickly and get it off the heat — every extra minute softens the crust you worked to build.
• Using full-sodium soy sauce at the listed quantity. The sauce reduces to a concentrate, and regular soy sauce at this amount will overpower everything else in the dish.

Variations to Try

• Stir a teaspoon of chili garlic sauce into the sauce base for a spicier version — the heat balances well against the sweetness without changing the fundamental character of the dish.
• Add blanched broccoli florets or thinly sliced bell pepper during the final wok toss for a more vegetable-forward plate that stretches the dish to five or six servings.
• Swap the flank steak for thinly sliced chicken breast for a lighter variation — reduce the fry time to about 60 seconds per side and proceed identically.

Storage & Reheating

Leftovers keep in an airtight container in the refrigerator for up to 3 days. Reheat in a hot skillet or wok over medium-high heat with a small splash of water to loosen the sauce. The microwave works in a pinch but softens the texture of the beef noticeably. The sauce flavors deepen overnight, so day-two leftovers are often better than they were fresh — just expect a softer crust.

What to Serve It With

Mongolian Beef belongs over steamed jasmine rice, which soaks up the extra sauce without competing with the flavor of the dish. For a more complete spread, a side of steamed or roasted broccoli is the classic pairing — it cuts through the sweetness and gives the plate some vegetable balance. A simple cucumber salad dressed with rice vinegar and sesame oil works equally well.

The Bottom Line

Frequently Asked Questions

What cut of beef does PF Chang’s use for Mongolian Beef?

PF Chang’s uses flank steak, sliced very thin against the grain. Flank is ideal because it’s lean, full of beefy flavor, and cooks in under two minutes at high heat without drying out. Skirt steak is the closest substitute and behaves nearly identically in this recipe.

Why is my beef not getting crispy?

The two most common causes are low oil temperature and overcrowding the pan. The oil needs to be close to 375°F before the beef goes in — if there’s no immediate, aggressive sizzle, wait longer. Fry in two batches so the temperature doesn’t drop, and give each piece space to brown rather than steam against neighboring slices.

Can I skip the frying step and just stir-fry?

You can, but the result will be noticeably different. Stir-frying in a small amount of oil produces softer, more conventional stir-fry texture. The brief deep-fry is what gives each slice the slightly crispy edge that makes Mongolian Beef distinct from other sauced beef dishes — it’s worth the extra step and the cleanup.

Why is my sauce not sticking to the beef?

The most likely issue is that the sauce wasn’t thick enough before you added the beef. Simmer the sauce until it visibly coats a spoon before starting the final toss. If the sauce looks thin during the wok toss, let it bubble over high heat for an extra 30 seconds — it should reduce quickly and start clinging to the beef.

Is this dish spicy?

The base recipe is not spicy at all — it’s primarily sweet and savory with mild garlic and ginger warmth. PF Chang’s standard version has no real heat. If you want some, a teaspoon of chili garlic sauce or sambal oelek stirred into the sauce before cooking adds a clean, building heat that works well with the sweetness.

Can I make the sauce ahead of time?

Yes — the sauce keeps in the refrigerator for up to 4 days in a sealed container. When you’re ready to cook, reheat it gently in the saucepan, whisking to re-emulsify it. The cornstarch causes the sauce to gel when cold, so add a tablespoon of water if needed to bring it back to the right consistency before using.
