Keto Beef and Broccoli Stir-Fry

The Origins and Keto Benefits of Our Beef and Broccoli Stir-Fry

Stir-frying is a time-honored cooking technique originating from the vibrant food culture of Asia. It’s a method that embraces the quick cooking of fresh ingredients, preserving their textures and nutrients. Our Beef and Broccoli Stir-Fry is a keto adaptation of this classic dish, ensuring you can enjoy the flavors you love without compromising your diet.

Flank steak, the star of this dish, is a fantastic source of lean protein and vital nutrients like iron and B vitamins. By slicing it thinly against the grain, we ensure each bite is tender and easy to digest. Broccoli, a cruciferous vegetable, is not only low in carbs but also packed with fiber, vitamins C and K, and antioxidants. These ingredients form the perfect duo for a keto meal that’s both nutritious and satisfying.

What sets our version apart is the careful selection of keto-friendly ingredients that replicate the umami-rich taste and velvety sauce of traditional stir-fries. We use coconut aminos as a soy sauce substitute, providing a similar savory flavor without the added sugars. The inclusion of a keto sweetener like erythritol ensures that the sauce’s sweetness is present without the carb load. And for those craving a thicker sauce, xanthan gum offers a low-carb solution to achieve the desired consistency.

Preparing Keto Beef and Broccoli Stir-Fry

Mastering the Method: Tips for the Perfect Stir-Fry

Creating the perfect stir-fry is an art form that balances texture, flavor, and timing. To start, ensure your skillet or wok is preheated to the right temperature. A medium-high heat is crucial for searing the beef quickly, locking in juices and creating a flavorful crust. When cooking the steak, avoid overcrowding the pan to ensure each piece browns evenly.

When it comes to the broccoli, the goal is to achieve a tender yet crisp texture. The key is to stir-fry the florets for just the right amount of time. Too short, and they’ll be too crunchy; too long, and they’ll lose their vibrant color and become mushy. Adding the minced garlic and grated ginger at the right moment is essential for infusing the oil with aromatic flavors without burning these delicate ingredients.

As you combine the beef and broccoli with the sauce, make sure to stir thoroughly, allowing the sauce to evenly coat the ingredients and simmer to the perfect thickness. If you’re using xanthan gum, remember that a little goes a long way. Start with a small amount and add more as needed to avoid an overly thick sauce.

Variations to Spice Up Your Keto Stir-Fry

Spicy Szechuan Beef and Broccoli

Craving heat? Add a Szechuan twist to your stir-fry by incorporating a tablespoon of chili garlic sauce and a sprinkle of crushed Szechuan peppercorns. These bold flavors will transform your dish into a fiery delight while keeping it keto-friendly.

Thai-Inspired Beef and Broccoli

For a Thai-inspired variation, mix in a tablespoon of sugar-free peanut butter and a splash of lime juice into the sauce. Garnish with chopped cilantro and crushed peanuts to bring a taste of Thailand to your kitchen.

Stir-Fry with a Creamy Twist

For a creamy version, stir in a quarter cup of heavy cream towards the end of cooking. This addition creates a luxurious sauce that pairs wonderfully with the savory beef and broccoli.

Substitutions for Your Keto Stir-Fry

While our recipe is designed to be keto-friendly, you may find yourself needing substitutions. If you don’t have flank steak on hand, thinly sliced sirloin or ribeye can be excellent alternatives, maintaining the high protein and fat content ideal for keto. For those avoiding soy, coconut aminos are a perfect substitute for soy sauce, offering a similar taste without the soy or added sugars.

Vegetable swaps are also possible. Try using cauliflower or green beans if you’re not a fan of broccoli. These veggies are equally low in carbs and can provide a different texture and flavor profile to your stir-fry.

  • Large skillet or wok
  • Mixing bowl
  • Whisk
  • Measuring spoons and cups


  • 1 lb flank steak, thinly sliced against the grain
  • 3 cups broccoli florets approx. 270g
  • 3 tbsp avocado oil, divided
  • 1 tbsp sesame oil
  • 3 cloves garlic, minced
  • 1 tsp fresh ginger, grated
  • ¼ cup soy sauce or coconut aminos
  • 2 tbsp beef broth
  • 1 tbsp erythritol or other keto-friendly sweetener
  • ½ tsp xanthan gum (optional, for thickening)
  • Salt and pepper to taste
  • Sesame seeds for garnish (optional)


  • Begin by preheating a large skillet or wok over medium-high heat.
  • While the skillet heats, in a small bowl, whisk together the soy sauce or coconut aminos, beef broth, erythritol, and xanthan gum (if using) until well combined. Set this sauce mixture aside.
  • Add two tablespoons of avocado oil to the skillet. Once hot, add the thinly sliced steak in a single layer, seasoning with salt and pepper to taste. Cook for 2-3 minutes on each side until browned and just cooked through. Remove the steak from the skillet and set aside.
  • In the same skillet, add the remaining tablespoon of avocado oil, followed by the broccoli florets. Stir-fry for about 3-4 minutes until the broccoli is tender yet crisp.
  • Push the broccoli to the sides of the skillet and add the sesame oil to the center. Add the minced garlic and grated ginger, stirring constantly for about 30 seconds, until fragrant.
  • Return the beef to the skillet with the broccoli. Pour the sauce mixture over the beef and broccoli, stirring to combine everything evenly.
  • Allow the stir-fry to simmer for 2-3 minutes until the sauce has thickened slightly and coats the beef and broccoli.
