| Ingredient | Amount | Notes |
|---|---|---|
| Flank Steak 🥩 | 1 ½ lb | Thinly sliced against grain |
| Peanut Butter 🥜 | ½ cup | Creamy, unsalted preferred |

| Honey 🍯 | 2 tbsp | For sweet-spicy balance |
| Sesame Oil 🫒 | 1 tbsp | Toasted for aroma |
| Roasted Peanuts 🥜 | ¼ cup | Crushed for texture |
| Garlic Cloves 🧄 | 4 cloves | Minced for depth |
| Ginger 🌿 | 1 tbsp | Freshly grated |

The flank steak is non-negotiable here—it delivers that signature tenderness when sliced thinly against the grain. Look for cuts with good marbling at Whole Foods or your local butcher shop; Costco often carries pre-sliced versions if you're short on time. The peanut butter should be creamy and unsalted—store brands work just fine, but Skippy or Jif are reliable choices. For the curry paste, Maesri or Thai Kitchen brands offer the perfect balance of heat and depth without overpowering the dish.
No red curry paste? Substitute 1 tbsp each of curry powder and cayenne for a similar effect, though the flavor won't be identical. The coconut milk must be full-fat canned—light versions won't give you that luxurious creaminess. For extra crunch, toast your peanuts in a dry pan for 5 minutes before crushing. The sesame oil should be toasted, not regular—it makes all the difference in aroma. If you're avoiding honey, maple syrup works in a 1:1 ratio, though the flavor profile shifts slightly.
Prep the sauce components ahead and store them separately in airtight containers for up to 5 days in the fridge. The beef can be marinated overnight for maximum tenderness. For the final assembly, keep the sauce at room temperature for 10 minutes before tossing with the beef—this ensures the perfect consistency. Leftovers keep for 3 days refrigerated, though the sauce may separate slightly; just stir vigorously before reheating. Freeze for up to 3 months if you're planning ahead.

Step-by-step instructions for crispy peanut sauce over tender beef
Master this fusion technique where perfectly seared beef meets a rich, crunchy peanut sauce.
🔪 Step 1: Prep and Slice the Flank Steak
Remove the 1.5 lb flank steak from packaging and pat it completely dry with paper towels. Place it on a cutting board and locate the grain direction—you'll see the muscle fibers running parallel. Using a sharp long knife, slice against the grain into ¼-inch thick strips. This against-the-grain technique ensures each bite has maximum tenderness.
Transfer the sliced steak to a bowl and toss with 1 tsp salt, 0.5 tsp black pepper, and 0.25 tsp white pepper. Let it marinate at room temperature for 15-20 minutes while you prepare the sauce. The marinade will penetrate the meat just enough to enhance flavor without making it mushy during cooking.
🍳 Step 2: Sear the Beef to Perfect Doneness
Heat 2 tbsp vegetable oil in a large skillet over high heat until shimmering. Add the marinated steak in a single layer and let it sear undisturbed for 1-2 minutes until the edges turn deep golden brown. This initial sear creates the Maillard reaction that develops rich flavor. Only then should you stir and continue cooking for another 2-3 minutes until the steak reaches 145°F internal temperature (about medium-rare for optimal tenderness).
Remove the steak from the pan and transfer to a clean plate. Tent loosely with foil to keep warm. The residual heat will carry the steak to perfect doneness while you finish the sauce. If the steak continues cooking, it will become slightly more done but still retain juiciness.
🍳 Step 3: Build the Peanut Sauce Base
In the same skillet (don't wipe it clean—the browned bits are flavor gold), reduce heat to medium. Add 2 tbsp vegetable oil if needed, then add the 4 cloves minced garlic and 1 tbsp freshly grated ginger. Sauté for 30 seconds until fragrant—this releases their aromatic oils. Immediately add 2 tbsp red curry paste and stir for 1 minute until it darkens slightly and becomes deeply perfumed.
Pour in 0.5 cup coconut milk and 2 tbsp soy sauce, scraping up any browned bits from the bottom of the pan. Let the mixture simmer for 2 minutes until slightly thickened. This forms the flavor foundation of your sauce—don't rush this step as the curry paste needs time to bloom properly.
🥘 Step 4: Create the Signature Peanut Sauce
Lower heat to low and stir in 0.5 cup peanut butter until completely smooth. Add 2 tbsp rice vinegar and 2 tbsp honey, whisking constantly until fully incorporated. The sauce should thicken noticeably as it comes together. If it's too thick, add 1-2 tablespoons water to reach your desired consistency—it should coat the back of a spoon but still be pourable.
Remove the pan from heat and stir in 1 tbsp sesame oil. The sauce should now have a rich, velvety texture with a perfect balance of sweet, spicy, and nutty flavors. Taste and adjust seasoning if needed—this is where you can make final flavor corrections before combining with the beef.
🥘 Step 5: Combine and Finish with Crunch
Return the steak to the skillet and pour the peanut sauce over it. Toss gently to coat the beef evenly with the sauce. Let it simmer together for 1-2 minutes until the steak absorbs some of the sauce and becomes glossy. This final step ensures every bite delivers perfect texture and flavor balance.
Transfer to serving plates and garnish with 0.25 cup crushed roasted peanuts. The contrast between the tender beef, rich peanut sauce, and crunchy peanuts creates the signature experience of this dish. Serve immediately with steamed jasmine rice or noodles to soak up every last bit of that delicious sauce.
Pro Tips For Making Bang Bang Beef
- SEAR FIRST, SAUCE LATER: Flank steak loves a screaming-hot pan—get it searing on all sides before pulling it out. I learned this the hard way: if you toss it into the sauce too soon, you’ll end up with a sad, gray slab instead of tender, caramelized beef. Two minutes per side, then let it rest while you build the sauce.
- WHISK THE PEANUT BUTTER: Dry peanut butter? Nope. Melt it into the coconut milk first, then whisk like you’re trying to win a pie-eating contest. That’s how you get a smooth, velvety sauce—not lumpy globs that scream "rushed." (Yes, even if you’re impatient like me.)
- DILUTE THE CURRY PASTE: Red curry paste is potent—start with half the amount listed and taste before adding more. I used to dump it all in and wonder why my dish tasted like a Thai fire drill. A splash of coconut milk first helps mellow the heat and balance the flavors.
- SWEAT THE GARLIC: Low heat, 3-4 minutes—let that garlic in the curry paste soften before adding the peanut butter. Burnt garlic ruins everything, and you’ll smell it before you taste the sweetness. (Your future self will thank you.)
Creative variations of this dish
Spicy Thai Fusion
Elevate your Bang Bang Beef with a Thai-inspired twist by adding 1 tbsp fish sauce and 1 tsp palm sugar to the peanut sauce base. I love using Thai Kitchen red curry paste for extra depth. Garnish with thinly sliced Thai basil and crushed dried shrimp for an authentic Southeast Asian touch. Serve with jasmine rice and a side of sweet chili mango salsa for a vibrant, balanced meal. 🌶️
Sweet & Smoky BBQ
Transform your Bang Bang Beef into a smoky BBQ masterpiece by swapping the peanut sauce for a BBQ glaze. Mix ½ cup BBQ sauce (like Sweet Baby Ray's) with 2 tbsp honey and 1 tbsp smoked paprika.

Serve with cornbread for a Southern-inspired twist. 🔥
Crispy Tofu Version
Make this dish vegetarian-friendly by replacing the beef with extra-firm tofu. Press and slice 1 block tofu into ¼-inch strips, then pan-fry in 2 tbsp avocado oil until golden and crispy. Toss with the peanut sauce and garnish with sesame seeds and green onions. The tofu absorbs the sauce beautifully, creating a satisfying texture contrast. Serve with quinoa or rice noodles for a protein-packed meal. 🌱
Creamy Miso Twist
Add umami depth by incorporating 1 tbsp white miso paste into the peanut sauce. Simmer the miso with the coconut milk and curry paste for 1 extra minute to fully integrate the flavors. Finish with a drizzle of yuzu kosho (a Japanese citrus chili paste) for a bright, tangy kick. Garnish with toasted sesame seeds and thinly sliced scallions. This fusion of Japanese and Thai flavors is a crowd-pleaser. 💛
Korean-Inspired Gochujang
Infuse Korean flavors by adding 1 tbsp gochujang (Korean chili paste) to the sauce base. Balance the heat with 1 tsp sugar and 1 tsp sesame oil. Top the beef with quick-pickled radishes and toasted sesame seeds for a crunchy, tangy contrast. Serve with steamed white rice and a side of kimchi for a bold, spicy, and savory experience. 🌟

Frequently asked questions
Can I use a different cut of beef instead of flank steak?
Sirloin or ribeye work beautifully—just slice them ¼-inch thick against the grain for tenderness. Skirt steak is another great option, though it has more connective tissue. Avoid tougher cuts like chuck; they won’t become tender enough in this quick cooking method.
How do I adjust the spice level in the peanut sauce?
Start by reducing the red curry paste to 1 tbsp for mild heat, or increase to 3 tbsp for extra spice. For a milder finish, add 1 tsp sugar or 1 tbsp honey to balance. If you love heat, stir in ½ tsp cayenne or 1 tsp sriracha at the end. Always taste as you go!
Can I make the sauce ahead of time?
Yes! Prepare the sauce base (without peanuts) up to 3 days ahead and store it in an airtight container in the fridge. Reheat gently, then stir in crushed peanuts just before serving. The sauce may thicken slightly when refrigerated—thin with 1 tbsp water if needed. Never freeze the full sauce, as it’ll separate.
What’s the best way to reheat leftovers?
Reheat in a skillet over medium-low heat with 1 tbsp water to prevent drying. Stir frequently for 3-4 minutes until warmed through. Avoid microwaving—it makes the sauce greasy. For extra crispiness, broil for 1-2 minutes after reheating. Leftovers keep for 3 days refrigerated.
Why is my sauce too thin or too thick?
Thin sauce? Simmer uncovered for 1-2 extra minutes to reduce. Too thick? Whisk in 1 tbsp water or coconut milk while warm. For texture, ensure you’re using creamy peanut butter (not chunky) and crushed peanuts (not whole). If the sauce separates, whisk vigorously or blend briefly for smoothness.
