Crispy Potatoes with Saucy Beef

This crispy potato and savory beef stir-fry combination delivers the perfect balance of textures in one delicious meal. The golden, crunchy potatoes provide the ideal canvas for the rich, saucy beef stir-fry packed with colorful vegetables and aromatic Asian flavors.

This dish became a regular in my rotation after discovering how the crispy potatoes soak up the flavorful sauce while still maintaining their crunch. My family requests it almost weekly, especially my husband who claims it satisfies both his potato and Asian food cravings in one dish.

Ingredients

• Potatoes: Medium-sized ones with a high starch content like Russets work best for maximum crispiness
• Beef: Sirloin or flank steak, choose well-marbled cuts for tenderness and flavor
• Bell peppers: Use both red and green for color contrast and different flavor profiles
• Soy sauce: Provides the essential umami foundation for the stir-fry sauce
• Oyster sauce: Adds rich complexity and slight sweetness to balance the savory elements
• Hoisin sauce: Optional, but highly recommended for depth and subtle sweetness
• Cornstarch: The secret to both crispy potatoes and a glossy thickened stir-fry sauce
• Green chili: Adds just the right amount of heat without overwhelming the dish

Step-by-Step Instructions

Parboil the Potatoes:

Start by boiling potato slices for exactly 5 minutes in heavily salted water. This crucial pre-cooking step ensures the potatoes develop a fluffy interior while allowing the exterior to become extra crispy during frying. Drain thoroughly and pat completely dry to prevent dangerous oil splatter.

Season and Fry to Perfection:

Heat vegetable oil to 350°F then carefully add potato slices without overcrowding. Fry until deeply golden brown and crisp around the edges about 4 minutes per side. The color should be rich amber not pale yellow. Immediately season with salt, pepper, and garlic powder while still hot so the seasonings adhere properly.

Marinate the Beef:

Toss thinly sliced beef with soy sauce, cornstarch, and black pepper allowing it to rest for at least 5 minutes. The cornstarch creates a protective coating that seals in juices during high-heat searing and helps thicken the sauce later.

Sear with Precision:

Heat your pan until smoking hot before adding oil. Quickly arrange beef strips in a single layer allowing them to sear undisturbed for 1 minute before flipping. The goal is caramelization not steaming so avoid overcrowding. Remove beef when still slightly undercooked as it will finish in the sauce.

Create Aromatic Base:

In the same pan with remaining beef juices add garlic, onion, and chili stirring constantly to prevent burning. The aromatic foundation should become fragrant but not browned in just 60 seconds. Add bell peppers next cooking just until they begin to soften but retain some crispness.

Build the Sauce:

Combine all sauce ingredients ensuring sugar fully dissolves in the liquid. Pour into the hot pan creating an immediate sizzle and begin scraping up flavorful browned bits from the bottom. Add the cornstarch slurry in a thin stream while stirring constantly to prevent lumps.

Final Integration:

Return beef to the sauce letting it simmer for exactly 1 minute until the sauce coats each piece with a glossy sheen. The sauce should thick enough to cling to meat and vegetables but still flow when spooned over the potatoes.

Pin it

My secret ingredient in this recipe is definitely the oyster sauce. I discovered its transformative power years ago when I accidentally added too much to a stir-fry but the richness it brought completely changed the dish. Now I keep a bottle permanently stocked in my kitchen for whenever I need that special umami boost.

Make-Ahead Options

You can parboil the potatoes up to a day ahead and store them covered in the refrigerator. Simply bring to room temperature before frying for best results. The stir-fry sauce components can also be mixed and stored in an airtight container for up to 3 days making weeknight assembly incredibly quick.

Perfect Pairings

This dish stands beautifully on its own but for special occasions I like to serve it with a simple cucumber salad dressed with rice vinegar to provide a cooling contrast to the rich beef. A small bowl of chili oil on the side allows heat-lovers to customize their experience while keeping the base dish accessible for everyone at the table.

Ingredient Substitutions

No beef available? Try thinly sliced chicken thighs or pork tenderloin with the same marinade. For a vegetarian version substitute firm tofu but be sure to press it thoroughly and add an extra tablespoon of soy sauce for flavor. Sweet potatoes can replace regular potatoes for a nutritional boost though they will yield a softer texture and sweeter flavor profile.

Frequently Asked Questions

Boil the potato slices briefly, pat them dry, and fry in hot oil until golden brown on both sides. Ensure the oil is heated to medium-high temperature before frying for best results.
