How to make Kung Pao beef
Place the beef in a bowl. In a separate mixing bowl, mix soy sauce with cornstarch until smooth, then whisk in brown sugar, rice vinegar, and sesame oil.
Add 2 tablespoons of the sauce to coat the beef and let it marinate for 15 minutes. Add the water to the remaining sauce and set aside.
Heat oil in a large skillet over medium-high heat, add the bell peppers and cook for 3–5 minutes until slightly tender.
Stir in garlic and ginger, cook for another minute.
Transfer the veggies to a bowl. In the same skillet, add more oil if needed and sear the steak in batches, cooking 2–3 minutes per side until browned.
Add the cooked beef to the bowl with the vegetables.
Add the peanuts and dried chili peppers into the skillet. Cook briefly, about 30 seconds to a minute, stirring constantly so they don’t burn.
Return the beef and vegetables to the skillet, pour in the reserved sauce, and sprinkle with red pepper flakes.
Stir everything together and let simmer on low heat for 3–4 minutes until the sauce thickens.
Serve with
Kung Pao beef is best served with steamed jasmine rice, which soaks up the flavorful sauce and keeps the meal balanced.
If you’re looking for something heartier, fried rice makes a great companion and adds another layer of flavor to the plate.
For a lighter option, garlic green beans or green bean almondine brings freshness and a crisp bite that pairs well with the spice.
You can also serve the stir fry over lo mein noodles for a more filling copycat takeout dinner.
Storing and reheating leftovers
Leftover Kung Pao beef keeps well in the refrigerator for up to three days when stored in an airtight container.
To reheat, warm it gently in a skillet over medium heat so the sauce loosens up and the beef stays tender.
The microwave also works for a quick option, though adding a splash of water before reheating helps prevent the sauce from becoming too thick.
Helpful Tips
- Slice Against the Grain: This helps the beef stay tender and easy to chew.
- Don’t Overcrowd the Pan: Cook the beef in batches to avoid steaming it.
- Adjust the Heat: Control the spice by using fewer dried chilies or removing the seeds.
FAQs

Kung Pao Beef
Equipment
Ingredients
- 1.75 pounds flank steak (sliced into ¼-inch thick strips)
- ¼ cup soy sauce
- 3 teaspoons cornstarch
- 3 tablespoons brown sugar
- 2 tablespoons rice vinegar
- 1 tablespoon sesame oil
- ⅓ cup water
- 1 – 2 tablespoons vegetable oil (for frying)
- 1 red bell pepper (deseeded and diced)
- 1 green bell pepper (deseeded and diced)
- ½ medium onion (diced into cubes)
- 3 cloves garlic (minced)
- 2 teaspoons fresh ginger (minced or grated)
- ¾ cup dry roasted peanut halves (lightly salted works well)
- 5 dried red chili peppers deseeded (leave some seeds if you prefer extra heat)
- 1 teaspoon red pepper flakes (or to taste)
- Sliced green onions (for garnish)
Serving suggestion
- Serve over white rice
Instructions
- Place the sliced steak in a large mixing bowl.
- In a separate bowl, whisk together soy sauce and cornstarch until smooth. Stir in the brown sugar, rice vinegar, and sesame oil until fully combined.
- Remove 2 tablespoons of this sauce and add it to the steak for marinating. Set aside for 15 minutes.
- Add the water to the remaining sauce, whisk until smooth, and keep aside for cooking.
- Heat a large skillet over medium-high heat. Once hot, sauté the bell peppers and onions for 3–5 minutes until softened slightly.
- Add the garlic and ginger, cooking for another 1–2 minutes until fragrant. Transfer vegetables to a clean bowl.
- In the same skillet, add more oil if needed and sear the steak in batches, cooking 2–3 minutes per side until browned. Transfer cooked beef to the bowl with the vegetables.
- Add the peanuts and dried chili peppers into the skillet. Cook briefly, about 30 seconds to a minute, stirring constantly so they don’t burn.
- Return the beef and vegetables to the skillet, pour in the reserved sauce, and sprinkle with red pepper flakes. Stir everything together and let simmer on low heat for 3–4 minutes until the sauce thickens.
- Garnish with green onions and serve hot over rice.
Notes
- Flank steak works best, but sirloin, round steak, or other lean cuts can also be used.
- Slice the beef against the grain for the most tender texture.
- If the sauce thickens too much, add a splash of water and stir it in until smooth.
- For milder heat, skip the dried chilies and stick to red pepper flakes. You can also use jalapeño slices or cayenne for a different kind of spice.
- Adjust the spice to your preference. Start with ½ teaspoon red pepper flakes and increase as needed.
- Cashews are a good alternative to peanuts. For a nut-free option, try water chestnuts for crunch.
- Bell peppers are classic, but other veggies like zucchini, mushrooms, broccoli, or snow peas can be added.
- Swap regular onions for strips of green onion if you like a lighter flavor.
- This dish goes well with white rice, fried rice, chow mein, or even as part of a plate with egg rolls or a side salad.
