  • 1 lb beef tenderloin, thinly sliced
  • 2 large sweet potatoes, spiralized into noodles
  • 1 cup cauliflower rice
  • 2 tablespoons coconut oil
  • 1 red bell pepper, sliced
  • 1 green bell pepper, sliced
  • 1 small onion, thinly sliced
  • 3 cloves garlic, minced
  • 2 tablespoons soy sauce (or coconut aminos for a soy-free option)
  • 1 tablespoon sesame oil
  • 1 teaspoon ginger, grated
  • Salt and pepper to taste
  • Sesame seeds for garnish (optional)
  • Green onions, chopped for garnish (optional)


  1. Heat a large wok over medium-high heat. Add 1 tablespoon of coconut oil and let it melt.
  2. Add the beef tenderloin slices to the wok. Stir-fry for 3-4 minutes until browned. Remove the beef from the wok and set aside.
  3. In the same wok, add the remaining tablespoon of coconut oil. Add the onion, garlic, and ginger. Stir-fry for about 2 minutes until fragrant.
  4. Add the bell peppers to the wok. Stir-fry for another 2-3 minutes until they start to soften.
  5. Toss in the spiralized sweet potato noodles. Stir-fry for about 5 minutes until they are tender but still slightly crisp.
  6. Push the vegetables to one side of the wok and add the cauliflower rice. Stir-fry the cauliflower rice for 3-4 minutes until it is tender.
  7. Return the beef to the wok. Pour in the soy sauce and sesame oil. Mix everything together and cook for another 2 minutes until everything is well combined and heated through.
  8. Season with salt and pepper to taste. Garnish with sesame seeds and chopped green onions if desired.

Serve this delightful Keto Beef Tenderloin Stir-Fry hot, and enjoy a healthy, low-carb meal that's both satisfying and delicious. Perfect for a family dinner or meal prep for the week!
