Ingredients You’ll Need

Here’s what goes into the perfect Beef and Broccoli Stir Fry with Mongolian Sauce:

• Beef: Flank steak or sirloin, thinly sliced against the grain.

• Broccoli: Fresh florets for that crunch and nutrition boost.

• Garlic & Ginger: Essential aromatics for authentic flavor.

Step-by-Step Instructions

1. Prepare the beef: Slice flank steak thinly against the grain. Toss with 1 tablespoon cornstarch and set aside.

2. Blanch the broccoli: Quickly boil or steam broccoli for 2–3 minutes until bright green and slightly tender. Drain and set aside.

3. Make the Mongolian sauce: In a small bowl, whisk together soy sauce, brown sugar, hoisin sauce, garlic, ginger, sesame oil, and ½ cup water. Add 1 tablespoon cornstarch to thicken.

4. Cook the beef: Heat oil in a large skillet or wok over high heat. Add beef in a single layer, searing until browned and just cooked through (about 3–4 minutes). Remove and set aside.

5. Combine everything: In the same pan, pour in the sauce and let it bubble until thickened. Add the beef and broccoli back into the pan, tossing until evenly coated.

6. Garnish & serve: Top with sliced green onions and sesame seeds. Serve over steamed rice or noodles.
