The Story Behind the Dish
Mongolian Beef, a staple of American Chinese cuisine, is all about contrast: crispy-edged beef against a glossy, addictive sauce. Despite its name, its roots are in Taiwanese-American restaurants. The key is the velveting technique for the beef, which guarantees that signature tender bite. This recipe breaks down the process into simple steps for a foolproof, spectacular weeknight dinner.
Ingredients
For the Beef & Marinade:
-
1 lb (450g) flank steak or skirt steak, sliced thinly against the grain
-
¼ cup cornstarch
-
¼ cup neutral oil (like avocado, vegetable, or canola)
-
2 cloves garlic, minced
-
1 tsp fresh ginger, minced
-
2-3 dried red chilies, optional (for heat)
For the Sauce:
-
½ cup low-sodium soy sauce (use tamari for gluten-free)
-
½ cup water or low-sodium beef broth
-
½ cup packed light brown sugar
-
1 Tbsp hoisin sauce
-
1 tsp toasted sesame oil
-
½ tsp freshly ground black pepper
For Serving:
-
3-4 green onions, sliced (green parts for garnish, white parts for cooking)
-
1 tsp toasted sesame seeds
-
Steamed jasmine rice or broccoli
Equipment Needed
-
Large wok or heavy-bottomed skillet
-
Two medium bowls
-
Whisk
-
Tongs or chopsticks
-
Paper towel-lined plate
Step-by-Step Instructions
Step 1: Velvet the Beef (Prep – 10 mins)
Place the thinly sliced steak in a medium bowl. Toss it thoroughly with the ¼ cup of cornstarch until every piece is evenly and lightly coated. This is the secret to the crispy exterior. Let it sit for 5-10 minutes while you prepare the sauce.
Step 2: Create the Signature Sauce (Prep – 5 mins)
In the other bowl, whisk together all the sauce ingredients: soy sauce, water/broth, brown sugar, hoisin sauce, sesame oil, and black pepper. Ensure the sugar is fully dissolved. Set aside.
Step 3: Fry the Beef (Cook – 5 mins – HIGH Heat)
-
Heat the ¼ cup of oil in your wok or large skillet over medium-high heat until it shimmers (about 350°F / 175°C).
-
Working in batches to avoid crowding, carefully add the coated beef slices. Fry for 1-2 minutes per side until crisp and browned. Do not stir immediately; let them sear.
-
Use tongs to remove the beef and place it on the paper towel-lined plate to drain.
Step 4: Build the Sauce & Glaze (Cook – 5 mins – MEDIUM-HIGH Heat)
-
Drain all but 1 tablespoon of the oil from the wok.
-
Reduce heat to medium. Add the minced garlic, ginger, the white parts of the green onions, and dried chilies (if using). Stir-fry for 30 seconds until incredibly fragrant.
-
Pour in the prepared sauce mixture. Bring to a simmer, then let it cook for 2-3 minutes, stirring occasionally, until it slightly thickens and becomes glossy.
Step 5: The Grand Finale (Cook – 2 mins)
Add the crispy beef back to the wok, along with any accumulated juices. Toss vigorously for 1-2 minutes until every piece is luxuriously coated in the sauce and heated through.
Chef’s Notes & Pro Tips
-
Slicing is Key: Partially freeze the beef for 20 minutes for easier, paper-thin slicing against the grain. This ensures tenderness.
-
Batch Fry: Crowding the pan steams the beef instead of frying it. Two batches are perfect.
-
Sauce Consistency: For a thicker sauce, create a slurry with 1 tsp cornstarch and 1 Tbsp water and stir it in during Step 4.
-
Make it Your Own: Add sliced bell peppers or onions with the aromatics. For extra veg, toss in steamed broccoli florets at the end.
Serving & Storing
-
Serve Immediately: Plate over a bed of fluffy steamed jasmine rice. Garnish generously with sliced green onions and a sprinkle of sesame seeds.
-
Storage: Store cooled leftovers in an airtight container in the refrigerator for up to 3 days. The beef will lose some crispness but the flavor remains excellent.
-
Reheating: Reheat gently in a skillet over medium heat. Microwaving will make the beef soggy.
