The flank steak is non-negotiable for this recipe—its lean texture cuts beautifully against the grain when thinly sliced. Look for grass-fed options at specialty butchers like D'Artagnan or your local Asian market for deeper flavor. Baby potatoes are ideal for their even cooking, but Yukon Golds halved into similar-sized pieces work just as well. The soy sauce should be Japanese-style (like Kikkoman or S&B)—it’s sweeter and less salty than American varieties, which balances the dish perfectly. Fresh ginger and garlic are essential; pre-minced jars lack the aromatic punch of freshly grated or minced ingredients.
No sesame oil? Toasted peanut oil works in a pinch, though the flavor will differ slightly. Substitute honey with maple syrup if needed, but reduce to 1.5 tbsp to avoid over-sweetening. For the potatoes, skip halving if they’re larger than 1.5 inches—cut them into even-sized pieces to ensure uniform crispiness. The brown sugar enhances the caramelization process, but white sugar in equal measure will suffice. If you’re short on green onions, scallions or chives provide a similar fresh finish. The rice vinegar adds brightness—substitute with apple cider vinegar if unavailable, though the flavor profile will shift slightly.
Store leftover beef and potatoes separately in airtight containers for up to 4 days in the refrigerator. Reheat gently in a skillet with a splash of water to restore crispiness. For longer storage, freeze portions for up to 3 months. The marinade components (soy sauce, honey, ginger, garlic) can be pre-mixed and stored in the fridge for up to 1 week, making prep day-of even simpler. The toasted sesame seeds and green onions are best added fresh after reheating to preserve their texture and aroma.

Step-by-step instructions for soy-glazed flank steak with crispy potatoes
This method delivers perfectly sliced beef with a glossy soy glaze and baby potatoes with contrasting textures—crispy edges and tender centers.
🍳 Step 1: Marinate and Prep the Flank Steak
In a bowl, combine the 0.5 cup soy sauce, 2 tbsp honey, 1 tbsp brown sugar, 1 tbsp rice vinegar, and 1 tbsp sesame oil. Whisk until the sugar dissolves completely. Add the 1.5 lb flank steak, sliced thinly against the grain, and coat evenly. Cover and refrigerate for at least 30 minutes—this ensures deep flavor penetration and tender slices.
While the steak marinates, preheat your oven to 425°F. Line a baking sheet with parchment paper and toss the 2 lb baby potatoes, halved lengthwise, with 3 tbsp vegetable oil, 1.5 tsp kosher salt, and 1 tsp black pepper. Spread them in a single layer, cut-side up, to maximize crispiness.
🔥 Step 2: Roast the Potatoes to Crispy Perfection
Roast the potatoes for 25-30 minutes, flipping halfway through, until they're deep golden brown and fork-tender. You'll know they're done when the edges are crispy and the internal temperature reaches 205°F—this ensures they hold their shape while still being tender. Remove them from the oven and set aside, keeping them warm.
Here's the thing—don't overcrowd the pan. If your baking sheet is small, roast them in batches. Overlapping potatoes steams them instead of browning, and we want that satisfying crunch.
🍳 Step 3: Sear the Marinated Steak
Heat a large skillet over high heat until it's smoking hot. Add the marinated steak in a single layer, leaving space between slices. Let them sear undisturbed for 1-2 minutes until the edges develop a deep caramelization. Flip and cook another 1-2 minutes until they reach 135°F internally—they'll carry over to 145°F, perfect for medium-rare.
Remove the steak from the pan and let it rest on a cutting board for 5 minutes. This resting period is critical—it allows the juices to redistribute, preventing dry slices. While it rests, return the skillet to high heat and add the 2 tbsp minced garlic and 2 tbsp grated ginger. Sauté for 30 seconds until fragrant.
🥘 Step 4: Combine and Finish with Glaze
Return the steak to the skillet and pour in any remaining marinade from the bowl. Add 1 tbsp toasted sesame seeds and 4 sliced green onions, reserving some for garnish. Simmer for 1-2 minutes until the sauce reduces slightly and coats the steak in a glossy sheen.
Slice the steak against the grain into ¼-inch thick strips and toss gently with the potatoes. The contrast of silky beef and crispy potatoes is what makes this dish special. Serve immediately, garnished with the reserved green onions and an extra sprinkle of sesame seeds for texture.
Pro Tips For Making Asian Beef And Potatoes
- Slice Against the Grain: Flank steak’s tough when chewed against its fibers—cut it perpendicular to the grain before cooking, then slice thinly after resting. I used to fight this and wondered why my beef felt like shoe leather.
- Boil Potatoes Twice: Parboil baby potatoes for 8 minutes, drain, then return to the pot for 2 more minutes with a splash of water. This trick guarantees they’ll crisp up perfectly in the pan later—no more mealy centers ruining the texture.
- Toast Ginger First: Grate fresh ginger, then dry-toast it in a hot pan for 30 seconds until fragrant. This deepens its flavor and cuts the raw bite—skip this, and your sauce will taste flat, even if you add extra.
- Use Less Soy Sauce: Start with just 1 tablespoon of soy sauce (not 2-3), then taste as you go. Soy sauce concentrates flavor when reduced, and overdoing it makes the dish taste salty and one-note—trust the process.
Troubleshooting great asian beef and potatoes
Potatoes Too Soft
If your potatoes turn out mushy instead of crispy, you likely roasted them at too low a temperature or didn't spread them out properly. Always use 425°F and arrange potatoes in a single layer with space between them. For extra insurance, I recommend tossing them with an extra ½ teaspoon of cornstarch before roasting—this creates a light barrier that keeps them crispy. 🥔
Steak Overcooked
Flank steak can dry out quickly if cooked past 145°F. Use a meat thermometer to monitor internal temperature—remove it when it hits 135°F (it'll rise to 145°F while resting). For extra tenderness, slice against the grain immediately after cooking while the meat is still slightly warm. 🥩
Sauce Too Thin
A runny sauce usually means the marinade didn't reduce enough. After searing the steak, let the pan get hot again and cook the sauce uncovered for 2-3 minutes to thicken it. If it's still too thin, whisk in ½ teaspoon of cornstarch mixed with 1 teaspoon water to create a slurry. Stir it in and cook for another 30 seconds.
Flavor Too Salty
If the soy glaze tastes overly salty, it's likely because the soy sauce or marinade was too concentrated. To fix this, add 1-2 teaspoons of honey or a splash of rice vinegar to balance the saltiness. For future attempts, reduce the soy sauce by 1 tablespoon and add 1 extra tablespoon of honey to the marinade for better balance.
Potatoes Undercooked
If your potatoes feel raw inside, they likely didn't roast long enough. Baby potatoes should reach 205°F internally. For even cooking, cut them into uniform sizes and flip them halfway through roasting. If they're still underdone, return them to the oven for 5-10 more minutes at 400°F to finish cooking without burning the exterior.
Steak Too Tough
Thinly slicing flank steak against the grain is key, but if it still feels tough, it might not have marinated long enough. For best results, marinate for at least 30 minutes (up to 4 hours** for deeper flavor). Also, ensure you're slicing perpendicular to the muscle fibers—this shortens the muscle fibers and makes each bite tender. 💪

Frequently asked questions
Can I use regular potatoes instead of baby potatoes?
Yes, but you'll need to adjust the cooking time. Cut larger potatoes (like Yukon Golds) into 1-inch chunks to ensure even cooking. They'll take 5-10 extra minutes in the oven compared to baby potatoes. The key is uniform size—this ensures crispy edges and tender centers.
What's the best way to slice flank steak for this recipe?
Slice the flank steak thinly against the grain—this means cutting perpendicular to the muscle fibers. Use a sharp knife and make ¼-inch thick slices for maximum tenderness. For a visual guide, look for the grain pattern (white lines) and cut across them.
How can I make this dish spicier?
Add ½ teaspoon of red pepper flakes or 1 teaspoon of gochujang (Korean chili paste) to the marinade for heat. For extra kick, sprinkle ½ teaspoon of cayenne pepper over the potatoes before roasting. Adjust to taste—start small and add more if needed.
Can I prepare this ahead of time?
Marinate the beef overnight for deeper flavor. Roast the potatoes the same day and store them separately in the fridge. Reheat the beef and potatoes together in a skillet for 3-5 minutes to restore crispiness. Add fresh sesame seeds and green onions just before serving.
What's the secret to crispy potatoes?
The secret is high heat and proper spacing. Roast at 425°F with potatoes in a single layer, cut-side up. Toss them with 3 tbsp oil and 1.5 tsp salt to enhance browning. For extra crunch, sprinkle with ½ tsp cornstarch before roasting.
