20 Minute Beef Teriyaki Noodles. Tender stir fried flank steak and noodles tossed in a homemade teriyaki sauce!
These Beef Teriyaki Noodles are comfort food at it’s finest. Tender cubed flank steak sauteed until tender and tossed with noodles and a homemade teriyaki sauce. It’s a super easy 20 minute meal!
To keep the beef extra tender I coat it in cornstarch before sauteing. This helps to thicken up the sauce as well as prevents overcooking and toughening of the meat. After it’s coated in cornstarch I flash fry the flank steak in very hot oil. I also like to cook my steak in batches to prevent overcrowding of the pan and to make sure the beef caramelizes on the outside.
The steak and noodles are coated in lots of sauce and finished off with sesame seeds and green onions.
The teriyaki sauce is made of equal parts soy sauce and mirin. Ginger, garlic and brown sugar also get added. The sauce gets nice and thick with a simple cornstarch slurry (1 teaspoon cornstarch + 1 tablespoon cold water).
These Beef Teriyaki Noodles are the perfect meal for a busy weeknight. All you need is one pan and 20 minutes! Enjoy!
