Let me tell you something about steak stir-fry. Most recipes take longer than they should, and the beef ends up tough and chewy. This Peppery Steak Stir-Fry is the opposite fast, tender, and packed with bold peppery flavor.
We're talking thin strips of round beef, coated in a savory tamari-based marinade with a kick of black pepper. Stir-fried with onions and red bell peppers until crisp-tender. All tossed in a quick sauce that thickens in seconds.
Fifteen minutes. One pan. And you've got a stir-fry that's faster than delivery and better than takeout.
The secret is cooking the beef in batches over high heat for just 20 seconds per side. That's right 20 seconds. That's how you get tender, juicy steak instead of chewy, overcooked rubber.

Alright, let's make a steak stir-fry that's fast, tender, and so flavorful. The key is high heat and short cooking time.
First, slice the beef. Cut the round beef into very thin strips. (For easier slicing, freeze the beef for 15-20 minutes first.)
Marinate the beef. In a bowl, combine the beef strips with 4 teaspoons of tamari, 1 tablespoon of rice wine, 1 teaspoon of buckwheat flour, and ½ teaspoon of black pepper. Stir to coat evenly. Set aside.
Make the sauce. In a separate small bowl, mix together 3 tablespoons of tamari, 1 tablespoon of water, and 2 teaspoons of buckwheat flour. Whisk until smooth. Set aside.
Heat your pan or wok over high heat. Add 1 teaspoon of coconut oil.
Cook the beef in batches. Add the beef to the pan in a single layer. Cook for 20 seconds without stirring this creates a nice sear. Then stir and cook for another 2 minutes, until the beef is browned but still tender. Transfer to a plate and set aside.
Reduce heat to medium. Add the remaining 1 teaspoon of coconut oil to the pan.
Add the sliced onion and red bell pepper. Cook for 4-5 minutes, stirring occasionally, until the vegetables are tender-crisp.
Return the beef to the pan. Pour in the tamari sauce mixture. Add red chili pepper flakes if you want heat.
Stir-fry for 30-60 seconds, until the sauce thickens and coats everything.
Serve immediately. Over rice if desired.
Eat with chopsticks or a fork. Get some beef, some veggies, and plenty of sauce in every bite.

Try my Keto Meal Prep Steak Bites and Zoodles recipe.
1| Freeze the beef for easier slicing. 15-20 minutes in the freezer firms up the meat, making it easier to cut thin, even strips.
2| Don't overcrowd the pan. Cook the beef in batches. If you add too much at once, it will steam instead of sear.
3| 20 seconds is not a typo. High heat + thin strips = very fast cooking. Overcooked beef is tough and chewy.
4| Use a hot pan. High heat gives you that wok hei the smoky, charred flavor of restaurant stir-fry.
5| Buckwheat flour is gluten free. It thickens the sauce smoothly without clumping. Cornstarch works too.
6| Taste and adjust pepper. Add more black pepper at the end if you want extra heat.
Try my Teriyaki Steak with Pak Choi and Noodles recipe.
1| Round beef is affordable. It's a lean, budget-friendly cut. Slice it thin and cook quickly that's the secret to tenderizing it.
2| Tamari is an investment. A bottle lasts for months of stir-fries. Regular soy sauce is cheaper but not gluten free.
3| Buckwheat flour in bulk. Buy only what you need. A little goes a long way.
4| Onions and bell peppers are cheap. One of each costs pennies.
5| Coconut oil lasts forever. A jar will last for months of cooking.
6| Make a double batch. Twice the stir-fry. Same amount of work. Freeze half.
