Ingredients
Sauce
- ¾ cup beef broth
- 1/3 cup low sodium soy sauce
- 3 tablespoons brown sugar
- 2 tablespoons honey
- 1 ½ tablespoons cornstarch
- 4 cloves fresh garlic, minced
- 1 teaspoon sriracha or hot sauce
- ¼ teaspoon ground ginger
- ¼ teaspoon sesame oil
Beef and Coating
- 1 lb flank steak (can substitute skirt, sirloin, or strip steak)
- Salt and pepper, to taste
- ¼ cup cornstarch
Cooking
- 2 tablespoons peanut oil (can substitute avocado or olive oil)
- ¼ cup beef stock
- 3-4 dried red chili peppers (optional)
- 3 green onions, sliced
- Steamed rice, for serving
Instructions
- Prepare the Sauce: In a bowl, combine the beef broth, soy sauce, brown sugar, honey, cornstarch, minced garlic, sriracha, ground ginger, and sesame oil. Mix well and set aside in a cool place to avoid prematurely activating the cornstarch. Gather the remaining ingredients before cooking.
- Tenderize the Beef: Place plastic wrap over the flank steak and gently pound it with a meat tenderizer or mallet to break down the fibers and ensure tenderness. Trim off any large fat areas if needed.
- Slice and Coat the Beef: Cut the beef against the grain into thin strips about ¼-inch thick. Pat the strips dry with paper towels, then lightly season with salt and pepper. Sprinkle the beef with ¼ cup cornstarch and toss until each piece is evenly coated.
- Sear the Beef: Heat peanut oil in a skillet over medium-high heat. In batches to avoid overcrowding, sear the beef strips for 3-4 minutes each until browned on each side. Remove the cooked strips and set aside.
- Prepare the Sauce Base: Turn the heat off briefly, then pour in ¼ cup beef stock. Turn heat back to medium and use a silicone spatula to scrape up any browned bits from the skillet edges and bottom, incorporating them into the sauce for extra flavor. Let the stock reduce by half over 2-3 minutes. If using dried red chili peppers, add them in the last 30-60 seconds.
- Cook the Sauce and Combine: Stir the prepared sauce mixture and pour it into the skillet. Bring it to a boil, letting it thicken, then reduce the heat to a simmer. Add the seared beef back to the skillet and toss well to coat in the sauce. Cook for another 2-3 minutes until the sauce thickens further and the beef is heated through.
- Serve: Remove from heat. Sprinkle sliced green onions over the dish. Serve immediately with steamed rice for a classic Mongolian beef meal.
Notes
- For tender beef, pounding the steak before slicing is essential to break down tough fibers.
- You can substitute flank steak with skirt, sirloin, or strip steak depending on availability and preference.
- Do not overcrowd the pan when searing the beef to avoid steaming the meat instead of frying.
- Dried red chili peppers add authentic heat but can be omitted or adjusted to taste.
- Serve with steamed white rice or brown rice for a balanced meal.
