Tender marinated beef slices, quickly sauteed and tossed with a homemade teriyaki sauce. Add this to a rice bowl with veggies and kimchi for a perfect fast dinner!
Combine the ingredients in a small sauce pan and bring to a simmer. Turn heat to low and simmer for 20 minutes, stirring regularly, until sauce thickens and coats the back of a spoon. Start this sauce very first so it's done when your other ingredients are done.
Sauce will continue to thicken if you let it cool and it can be made well in advance.
To Make Velveted Stir-Fry Beef:
Slice beef into thin slices (no wider than 1/4-inch thick). Add sliced beef to a bowl and rinse well with cold water, agitating the beef and pressing it with your hands. Drain well.
To the bowl with the rinsed beef, add baking soda, soy sauce, mirin, salt, and pepper and stir to combine. Allow to marinate for 10 minutes.
In a large wok or large saute pan, heat over medium-high heat. Once hot, add oil and then the marinated beef. You might want to cook in batches. Quickly stir-fry the beef, cooking for 3-4 minutes until beef is browned in spots and just cooked through. Repeat with second batch if needed.
After beef is cooked, return to wok over low heat and toss with 1/4 cup of the teriyaki sauce. Cook for 1-2 minutes to thicken sauce. Remove from heat and serve while warm.
Serving teriyaki bowls:
Serve the stir-fried teriyaki beef in bowls with rice, chopped snap peas, kimchi, scallions, sesame seeds, and additional sauce on the side.
