Quick easy and yet so delicious. This beef is coated in cornstarch and deep fried until extra crispy, then glazed with a sweet brown sugar soy sauce. This is so good you will mistake it for meat candy!
Mix all the ingredients of the marinade in a deep dish and store in the fridge for at least 2 hours, up to overnight.
When ready to fry, take the beef out of the marinade and let it rest until room temp, about 30 minutes.
Slice beef into 2 inch slices against the grain so they are thin strips. Coat in the cornstarch.
Heat about 2-3 inches of oil in a deep cast iron skillet or dutch oven to 350 degrees F. When ready drop each piece into the oil trying to avoid overcrowding. Fry until crispy, flipping halfway through, about 3 minutes per side. Drain onto a paper towel lined baking sheet.
While the beef is frying, make the sauce. Combine all sauce ingredients except cornstarch water slurry into a sauce pan and bring to a boil. Once boiling reduce to a simmer and allow the sauce to cook down into a thick glaze, about 4-6 minutes. Towards the end of simmering, add the cornstarch slurry and watch the sauce thicken right up! Set aside.
When beef is fried and sauce is thick, throw all ingredients into a large bowl and toss until the beef is coated in the glaze. Sprinkle on scallions and sesame seeds to serve.
