This beef and cashew stir fry delivers restaurant-quality crispy wok crunch with nutty sweetness that balances perfectly. The secret lies in high-heat searing of the beef followed by a quick toss with toasted cashews and a glossy ginger-soy glaze.
I've perfected this technique to ensure tender beef strips with crispy edges and cashews that stay crunchy—not soggy—throughout the stir-fry.
What sets this recipe apart is the 30-minute preparation time that still delivers depth of flavor. The beef marinates briefly in a simple soy-ginger mixture while you prep the vegetables, and the cashews toast in the same wok after the beef is removed—maximizing flavor without extra effort.
Every bite combines tender beef, crunchy cashews, and vibrant vegetables coated in a sticky-sauce that's both sweet and savory.
The result is a dish that's elegant enough for dinner guests but simple enough for weeknights. The cashews add texture and richness, while the ginger-soy sauce cuts through the beef's richness with bright, aromatic notes.
Serve over steamed jasmine rice or noodles to soak up every last bit of that flavorful sauce.
For an extra touch of freshness, finish with sliced green onions or sesame seeds. This stir-fry keeps well for up to 3 days in the fridge, making it perfect for meal prep. Let's create this wok-worthy dish that'll have everyone asking for seconds.

The beef is non-negotiable here. Flank steak delivers that perfect tender-yet-crispy texture when sliced thinly against the grain. Most butchers will slice it for you if you ask—they call it 'chiffonade' style. For cashews, Trader Joe's or Costco have the best prices in bulk, and they're already shelled. Look for vibrant, plump cashews with no cracks or discoloration. The ginger and garlic? Fresh is essential—dried won't give that bright, zesty punch the sauce needs. I always grab a whole ginger root and grate what I need, keeping the rest in the freezer.
No flank steak? Sirloin or ribeye work too, but slice it thinner than you think you need. Running out of cashews? Peanuts or almonds toast just as well—peanuts add a slightly earthier note. The soy sauce is where flavor happens, so Kikkoman or La Choy are solid choices. For extra depth, add a dash of fish sauce if you're not avoiding it. The honey can be swapped for maple syrup or agave, but honey gives that classic stir-fry sweetness. And that sesame oil? Use sparingly—it's aromatic, not flavorless. Add it at the very end to preserve its perfume.
This stir-fry reheats beautifully—just toss with a splash of water or soy sauce to keep it moist. Keeps in the fridge for 3 days, though it's best within 24 hours for maximum crunch. For meal prep, store components separately: beef and veggies in one container, sauce in another, and toast the cashews fresh when reheating. The rice? Cook it in advance—it reheats better than you'd think. Garnishes like sesame seeds and green onions should go on fresh after reheating to keep that pop of color and texture.

Step-by-step instructions for beef and cashew stir fry
Master this wok technique for perfectly seared beef and crunchy cashews every time.
Prepare the Flank Steak for Maximum Tenderness
Slice the 1 lb flank steak thinly against the grain using a sharp knife—you want strips about ¼-inch thick. This ensures each bite will be tender despite the quick cooking. Pat the sliced steak dry with paper towels to remove any surface moisture, which helps create that crispy sear we're after.
In a small bowl, combine 0.5 tsp salt and 0.25 tsp black pepper, then toss the steak strips in this mixture until evenly coated. Let the seasoned steak sit at room temperature for 15 minutes before cooking. This step guarantees even cooking and maximum flavor penetration throughout each slice.
Toast the Cashews and Prep Vegetables
Spread the 0.5 cup whole cashews on a dry baking sheet and toast in a 350°F oven for 5-7 minutes until they're golden brown and fragrant. Keep a close eye on them—they burn quickly. Remove from the oven and let cool completely before using. Toasted cashews add that essential crunch and nutty depth to the dish.
While the cashews toast, slice the 1 whole yellow onion and 1 whole red bell pepper into thin strips. Mince the 4 cloves garlic and grate the 1 tbsp fresh ginger. These aromatics form the flavor base of our stir fry, so take your time to get them uniformly chopped. The ginger should be finely grated—you should barely see any texture when you look at it.
Cook the Beef to Perfect Doneness
Heat a large wok or skillet over high heat until it's smoking hot. Add 2 tbsp vegetable oil and swirl to coat the bottom evenly. Working in batches if needed, add the seasoned steak strips and cook undisturbed for 1-2 minutes until they develop a deep golden brown crust on one side. This initial sear locks in juices and builds flavor.
Flip the steak and cook for another 30-45 seconds until it reaches medium doneness (about 145°F internal temperature). Remove the beef from the wok and set aside. Don't overcrowd the pan—cooking in batches ensures proper browning. The steak should be cooked through but still slightly pink in the center for perfect texture.
Build the Stir Fry Sauce and Combine Ingredients
In the same wok, reduce heat to medium-high and add the sliced onions and bell peppers. Stir-fry for 2-3 minutes until they begin to soften but still retain their color. Add the minced garlic and grated ginger, cooking for another 30 seconds until fragrant—this is when your kitchen should smell amazing.
Pour in the 0.5 cup low-sodium soy sauce and 1 tbsp honey, then immediately add the 1 tbsp sesame oil. Stir well to combine, then return the cooked beef to the wok. Toss everything together for 1-2 minutes until the beef is evenly coated in the sauce. The sauce should be glossy but not watery—if it's too thick, add 1-2 tablespoons of water to loosen it.
Finish with Crunch and Serve Immediately
Add the toasted cashews and toss everything together for 30 seconds to distribute them evenly. Stir in the sliced 3 whole green onions and sprinkle with 1 tbsp toasted sesame seeds. The cashews should maintain their crunch while the beef stays tender and the vegetables crisp-tender.
Serve the beef and cashew stir fry immediately over 1.5 cups cooked jasmine rice, garnished with additional sesame seeds if desired. The dish should be hot, with each bite delivering perfectly seared beef, crunchy cashews, and a balance of sweet, salty, and umami flavors. Leftovers? Reheat gently in a skillet to maintain that crispy texture.
Pro Tips For Making Beef And Cashew Stir Fry
- Slice Steak Against the Grain: Flank steak’s tough fibers need to be cut perpendicular to the grain—otherwise, you’ll end up with chewy, rubbery bites. Grab your knife and slice before cooking, then store the strips in a sealed bag in the fridge. Trust me, this 5-minute prep step changes the texture completely.
- Toast Cashews Low and Slow: Skip the high-heat blitzing—cashews burn faster than you’d think. Spread them on a dry pan over medium-low heat, stirring constantly, until they’re just golden (about 3-4 minutes). Overcooking turns them bitter, and nobody wants that nutty regret.
- Prep Veggies in Strips, Not Dice: Thin, even strips of onion and bell pepper cook faster and stay crispier than dice. Cut them lengthwise into ¼-inch-wide matchsticks—this keeps the stir-fry vibrant and ensures everything hits the wok at the same time. (Yes, it looks fancier too.)
- Rest the Steak After Cooking: I learned this the hard way—rushing the steak straight into the sauce makes it dry out. Give it a solid 5 minutes under foil, tented loosely, while you prep the rest. The residual heat keeps it juicy, and you won’t end up with a sad, leathery bite.
Serving suggestions for this recipe
Rice Pairings
Jasmine rice is my go-to here—its delicate floral aroma complements the nutty sweetness of the cashews and beef beautifully. Cook 1.5 cups uncooked jasmine rice to yield about 3 cups cooked, which is perfect for serving 4 people.
For extra fluffiness, rinse the rice 3 times before cooking to remove excess starch. 🍚
Looking for alternatives? Try short-grain sushi rice for a stickier texture that holds up well to the stir-fry sauce. Or go for brown rice if you prefer a nuttier, heartier base—just increase cooking time by 20-25 minutes and add ½ cup extra water.
Noodle Options
For a lighter presentation, serve over udon or soba noodles. Cook 8 oz dried noodles according to package instructions, then drain and rinse briefly under cold water to stop cooking. Toss with 1 tsp sesame oil before adding the stir-fry to prevent sticking. 🍜
Want something more rustic? Ramen noodles work wonderfully—their chewy texture contrasts perfectly with the crispy cashews. Just discard the seasoning packet and use the noodles plain. I like to add 1 tbsp extra soy sauce to the stir-fry sauce when serving over noodles for enhanced flavor.
Fresh Garnishes
Finish with 3 sliced green onions for a bright, fresh pop of color and mild onion flavor. Sprinkle with 1 tbsp toasted sesame seeds right before serving to add crunch and visual appeal.
For an extra touch, I sometimes add ¼ cup chopped cilantro if I have it—it adds a citrusy brightness that cuts through the richness. 🌿
Don't overlook the power of a lime wedge on the side. A squeeze of fresh lime juice right before eating enhances all the flavors and adds that classic Asian restaurant touch. Trust me, it makes a world of difference!
Sauce Enhancements
If you love heat, drizzle with 1 tsp chili crisp or ½ tsp sriracha before serving. For a smoky depth, add ½ tsp smoked paprika to the sauce while cooking. Both options elevate the dish without overpowering the delicate balance of flavors. 🌶️
For a creamy twist, stir in 1 tbsp hoisin sauce when combining the stir-fry ingredients. It adds a subtle sweetness and thickness that pairs beautifully with the cashews. I like to keep a small bottle of hoisin in my pantry specifically for stir-fry upgrades.
Meal Presentation
Serve in a wide, shallow bowl to showcase the vibrant colors and textures. Use a wooden spoon for serving to add a rustic touch. For an extra-special presentation, arrange the stir-fry in a circle with the rice forming a base, then place the beef and cashews in the center. 🍽️
Add a side of steamed bok choy or quick-pickled cucumbers to balance the richness. The crisp, cool contrast makes each bite even more satisfying. I always keep a small jar of pickled vegetables in the fridge for moments like this—it takes minutes to prepare and adds that restaurant-quality touch.
Nutrition facts
Frequently asked questions
Can I use ground beef instead of flank steak?
While ground beef works in a pinch, it won't give you that same tender, restaurant-quality texture. For best results, stick with flank steak sliced thinly against the grain. If you must use ground beef, look for lean 90/10 and cook it separately until browned before combining with the stir-fry to prevent a greasy texture.
How do I keep the cashews from getting soggy?
Toast the cashews separately in the oven until golden and fragrant, then add them to the wok only at the very end. Toss them for just 30 seconds with the hot stir-fry to maintain their crunch. Never add them while the sauce is simmering, as the moisture will turn them soft.
What's the best way to reheat leftovers?
Reheat gently in a skillet over medium heat with 1 tbsp water or soy sauce to prevent drying. Stir constantly for 2-3 minutes until warmed through. For extra crispiness, toast fresh cashews and sprinkle them on top after reheating. Leftovers keep well for 3 days in the fridge.
Can I make this dish gluten-free?
Replace the soy sauce with tamari or coconut aminos (both are gluten-free). Just use the same measurements. Also check that your sesame oil and any other ingredients (like hoisin sauce) are certified gluten-free if needed.
What vegetables can I add for extra nutrition?
Broccoli florets, snap peas, or sliced mushrooms work beautifully. Add them with the onions and bell peppers, but cook them for 1-2 minutes less than the other vegetables since they take longer to soften. For extra color, try thinly sliced carrots or shredded cabbage.
