This crispy potato and saucy beef stir-fry combines the best of both worlds: golden, crispy potato slices paired with tender beef strips in a rich Asian-inspired sauce. The contrast between the crunchy potatoes and the savory, glossy beef creates a satisfying texture combination that makes this dish irresistible.
I created this recipe when my family was craving both Asian flavors and comfort food. The crispy potatoes remind me of my grandmother's cooking, while the saucy beef brings in flavors from my favorite takeout spots.
Ingredients
- Potatoes Medium starchy varieties work best as they get crispy outside while remaining fluffy inside
- Olive oil Helps season the potatoes before frying for extra flavor
- Salt Black pepper and garlic powder This trio creates the perfect seasoning base for crispy potatoes
- Vegetable oil Choose one with a high smoke point for proper frying without burning
- Beef sirloin or flank steak Look for well-marbled cuts for tenderness and flavor
- Soy sauce Adds umami depth and helps tenderize the beef
- Cornstarch Creates a velvety texture on the beef and thickens the sauce
- Bell peppers Add sweet crunch and vibrant color to the dish
- Onion and garlic The aromatic foundation that builds flavor complexity
- Green chili Adds a pleasant heat that balances the rich sauce
- Oyster sauce Provides savory richness that can't be matched
- Hoisin sauce Adds a sweet and tangy dimension to the sauce
- Beef broth Forms the liquid base of the sauce, enhancing the meaty flavor
Step-by-Step Instructions
- Prepare the potatoes
- Boil potato slices in well-salted water for exactly 5 minutes until they're just tender but still hold their shape. This precooking step ensures they'll fry up crispy on the outside while remaining creamy inside. After draining, thoroughly pat them dry with paper towels to remove all moisture this is crucial for achieving maximum crispiness.
- Fry to golden perfection
- Heat about ¼ inch of vegetable oil in a large skillet until shimmering but not smoking. Carefully add potato slices without overcrowding the pan, working in batches if needed. Let them fry undisturbed for 4 minutes before flipping to develop that golden crust. The second side will cook slightly faster, about 3 minutes. Transfer to paper towels and immediately season while hot so the flavors adhere.
- Marinate the beef
- In a medium bowl, thoroughly coat beef strips with soy sauce, cornstarch and black pepper. Let sit for at least 5 minutes but no more than 15 minutes as the soy sauce can start to cure the meat. The cornstarch creates a protective coating that keeps the beef juicy when seared at high heat.
- Sear the beef
- Heat your pan until it's very hot before adding oil this prevents sticking. Add beef strips in a single layer without overcrowding they should sizzle immediately on contact. Cook for just 2 minutes without disturbing, then quickly stir and cook for another minute. The beef should be browned but still slightly pink inside. Remove promptly to prevent overcooking.
- Build the aromatics
- Without cleaning the pan, add garlic, onion and green chili to the remaining oil and beef juices. Keep everything moving constantly to prevent burning the garlic. You want the onions to become translucent but not browned. Add bell peppers next, cooking just until they brighten in color but remain crisp-tender.
- Create the sauce
- Whisk together soy sauce, oyster sauce, hoisin, sugar and beef broth until well combined. Pour into the hot pan, scraping up any browned bits from the bottom these contain concentrated flavor. Bring to a simmer before adding the cornstarch slurry, making sure to stir it again right before adding as it settles quickly.
- Finish the dish
- Return beef to the pan and toss everything together for just 1 minute until the sauce thickens and turns glossy. It should coat the back of a spoon but still flow. Avoid overcooking at this stage to keep the beef tender and the vegetables crisp.

The oyster sauce is truly the secret weapon in this recipe. I discovered its magic years ago when cooking with my Chinese neighbor who insisted it was the key to authentic flavor. She was right the depth it adds is unmatched by any other ingredient.
Serving Suggestions
This dish is fantastic served over steamed rice which soaks up the delicious sauce. For a lower-carb option, try it with cauliflower rice or simply enjoy it as is with the potatoes as your starch component. A side of simple steamed broccoli or bok choy adds extra vegetables and color to complete the meal.
Make It Your Own
Feel free to customize this recipe based on what you have on hand. Chicken, pork or even firm tofu can replace the beef. The vegetable combination is flexible too try adding mushrooms, snow peas, or carrots. If you prefer a spicier dish, increase the green chili or add red pepper flakes. For a sweeter profile, add a tablespoon of pineapple juice to the sauce.
Storage Tips
The beef stir-fry portion keeps well in the refrigerator for up to 3 days in an airtight container. However, the crispy potatoes are best enjoyed fresh as they lose their crunch when stored. If you know you'll have leftovers, consider cooking only the amount of potatoes you'll eat immediately and making fresh ones when reheating the beef mixture. Reheat the beef gently in a skillet with a splash of water to revive the sauce.
