Ingredients
- 1 ½ LB flank steak
- 1 medium sweet onion, chopped in 1” chunks
- 1 large green bell pepper, chopped in 1” chunks
- 1 large red bell pepper, chopped in 1” chunks
- 4 large garlic cloves, minced
- 1-inch piece of ginger, peeled and grated
- ½ cup corn starch
- 8 TBL premium soy sauce, divided
- 3 TBL rice wine
- 1 tsp. sesame oil
- 1 tsp. cracked black pepper
- ½ cup corn starch
- 2 TBL black vinegar
- 2 TBL oyster sauce
- 2 TBL chili crisp in oil
- 1 TBL doubanjiang (spicy bean paste)
- 1 TBL demerara sugar
- 3 TBL peanut oil, divided
- 2 TBL white sesame seeds
Instructions
Trim all extra fat from the flank steak, making sure to get rid of all silver skin. Silverskin is an extremely tough connective tissue commonly found on beef and pork tenderloins. Because it's tough, chewy, and doesn't melt during cooking like fat does, silverskin must be removed before cooking. Now cut the flank steak in half, lengthwise. Next, holding your knife at a 45-degree angle, cut the flank steak against the grain to make 1.5-2” X .5” strips.
In a glass or non-reactive bowl, mix the steak with 5 TBL of the soy sauce, the rice wine, sesame oil, black pepper, and corn starch. Toss the beef well in the ingredients to fully coat the flank. Cover and refrigerate for 2 hours.
The Pepper-Garlic Sauce:
In a small mixing bowl, combine 3 TBL of the soy sauce, the black vinegar, oyster sauce, chili crisp, Doubanjiang (bean paste), and sugar. Whisk ingredients thoroughly and set aside.
In a very hot wok, or deep-sided sauté pan, add 2 TBL of the peanut oil. Once the oil shimmers, add the beef in batches (about 4) and stir fry 2 minutes or until the beef gets a nice sear. Remove the beef and set aside on a drainage rack and repeat the process until all the beef is seared.
In the empty wok, add 1 more TBL of peanut oil. Once the oil shimmers, add the sesame seeds and stir fry until fragrant and slightly toasted. Next, add the garlic, ginger, peppers, and onions and stir fry about 1 ½-2 minutes. You are looking for the peppers to turn a very bright color and the onions to become translucent. Do not overcook the vegetables because you want them to remain crisp.
Add back in the beef and add the sauce and stir fry an additional minute. The sauce will begin to thicken at this point.
I love this over jasmine rice, of course, but you can serve it over shredded cabbage if you are going carb-free.
