BOK CHOY Bok choy is part of the cabbage family but has sweet undertones to it which makes it great to cook for stir-fries, plus it maintains a little bit of crunch even after cooking. If overcooked, the tender-crisp texture. It can be cut into larger pieces or sliced if desired.

BEEF Marinated beef is both tender and flavorful. It should be added to the skillet along with a savory and spicy sauce.

SAUCE The sauce is made with Hoisin, broth, sriracha, and sesame oil. It’s sweet and savory with a bit of a kick. If you’d prefer you can use a premade stir fry sauce.


All stir fry recipes have the advantage of being excellent ways to use up leftovers!

  • Add baby corn, broccoli, zucchini, or mushrooms.
  • Beef can be switched out for chicken, pork, shrimp, or even tofu!
  • Serve Bok choy stir fry on top of white rice, brown rice, fried rice, or udon noodles!

How to Cut Bok Choy for Stir Fry

Every part of bok choy can be used!

  1. Slice an inch from the bottom root of the bok choy. Separate the leaves and rinse them. Pat each leaf dry and stack the leaves on top of each other.
  2. Cut the white stem away from each side of the leaves. Collect the stems and cut them into pieces (about 1/2″ thick).
  3. Coarsely cut the leaves into 2″ pieces, they’ll shrink as they cook.

  1. This is going into my favorites box. I had 2 small steaks that I thinly sliced but it was a perfect amount with about half of a bok choy. I made it according to the recipe however so there was plenty of sauce. The meat was probably the most tender rendition of stir fry that I have ever eaten. My husband was thrilled and ate more than he planned. Quick and easy is great when it’s a bit too hot to stand at the stove for very long! Thanks so much.5 stars

  2. I made this recipe and we loved it. I didn’t have quite enough steak, so I added some lean ground beef. It was just as good as the steak. This is a keeper, in fact, I have the page bookmarked for easy access.

  3. Received a large Bok Choy in my CSA weekly pick up. Wasn’t sure just what to do with it. Tried this recipe and it was delicious! Husband liked it enough to have the leftovers for dinner the next night and he is not real keen on trying out new vegetables.5 stars

  4. I love this recipe! We eat it at least twice a month. Your recipes are so solid and creative! Thanks for your commitment to excellence in cooking!5 stars

  5. I made this for my family and it was SOOO good!!! Thank you so much! My whole family enjoyed it except for my 1 picky eater who won’t eat anything green, but he ate the beef. Ha! The only thing I changed was when I switched it to 6 servings it told me to add 1/2 cup of corn starch to the beef marinade which seemed like way too much, so I just lessened it by about half and the sauce and all still turned out great! I’ll definitely make this again! =)5 stars

  6. I tried this recipe twice and ended up with the same results both times. The marinade 1/3 cup of cornstarch is too much. The cornstarch burns and sticks to the pan creating a ball of dough like burnt mess. The third time I made it I used a teaspoon of cornstarch and it worked just fine.
    Please let me know if the 1/3 cup still stands

    1. Hi John, the ingredients are correct as written. We retested this recipe to understand the issues. We found that instead of mixing the cornstarch and soy sauce like a marinade, you sprinkle the beef with the cornstarch, then sprinkle it with the soy sauce. It doesn’t create a marinade in the sense of a liquid marinade, and that word may have caused some confusion. They are sprinkled separately and then mixed with the beef.

      I hope this helps explain it better and clears up any confusion.

  7. I made this today and it was outstanding! I added Julienned carrots and red bell pepper and served everything over rice. DELISH!!! Will make it again.5 stars

  8. I think this recipe has a mistake. I believe it should be 1/3 c. Soy sauce and 2 tbs cornstarch for the meat marinade. I’ve never seen a recipe calling for 1/3 c. Of cornstarch….

  9. This was so easy….and delicious. I think the marinating is so important to give the meat that authentic taste…my family loved this.5 stars

  10. I, too, had a tough time with the ‘marinade’. I tried to combine the corn starch with the soy sauce first before adding the meat and it came together like a brick. Had to break it up into pieces and add more liquid which made the whole dish taste like nothing. I think if I had added the meat to a bowl, poured the soy sauce over it, mixed it well, then sprinkled the corn starch and mixed again, it would have adhered better and the consistency would have been correct. Too bad for me…

    1. Hi Jane, we add the two ingredients on top of the meat (as can be seen in the images) and mix together (not mixing the cornstarch with the soy sauce before adding the meat). The way you mentioned would work well also!

  11. Made exactly as directed and it turned out great. Loved how thick the sauce got. Was going to post a pic but didn’t see that as an option.5 stars

    1. So happy this recipe worked well for you, Faye! We would love to see your pictures, tag us on Instagram using @spendpennies.

  12. This is really confusing. One part says ingredients 1/3 cup cornstarch. Sauce is second part that you pour over everything when it is done. So if you add 1/3 cup of cornstarch to 2 tablespoons of soy sauce, it is too thick to put the meat in. I am so confused and I have been cooking for over 50 years.3 stars

    1. Hi Darlene, we toss the beef soy sauce and 1/3 cup cornstarch in a bowl. It is thick, kind of like you would flour chicken before pan frying it. This helps tenderize the beef and makes it get a crust.

      Only 2 teaspoons of cornstarch are added to the sauce (in the list of sauce ingredients). We pour the sauce mixture over top the beef in step 5. Hope that helps!
