Ingredients

• 400 grams Beef sirloin (thinly sliced)
• 1 unit Onion (medium, sliced)
• 3 cloves Garlic (minced)
• 3 tablespoons Soy sauce (low-sodium)
• 1 tablespoon Sesame oil
• 2 tablespoons Olive oil or avocado oil
• 2 stalks Green onions (sliced for garnish)
• 0.25 teaspoon Salt
• 0.25 teaspoon Black pepper (freshly ground)
• 0.25 teaspoon Red pepper flakes (optional)

Directions

Step 1

Thinly slice the beef sirloin against the grain and place it in a medium bowl.

Step 2

In the bowl with the beef, add 2 tablespoons of soy sauce, 1 tablespoon of sesame oil, and a pinch of black pepper. Mix to coat the beef evenly and let it marinate for 10 minutes while prepping other ingredients.

Step 3

Slice the onion into thin wedges and mince the garlic. Set aside.

Step 4

Heat a large wok or skillet over medium-high heat. Add 1 tablespoon of olive oil or avocado oil and let it heat until shimmering.

Step 5

Add the marinated beef to the wok in a single layer. Stir-fry for 2-3 minutes until browned but not completely cooked through. Remove the beef from the wok and set it aside.

Step 6

In the same wok, add another tablespoon of olive oil or avocado oil. Add the sliced onions and stir-fry for 2-3 minutes until they start to soften.

Step 7

Add the minced garlic to the onions and stir-fry for another 30 seconds until fragrant.

Step 8

Return the beef to the wok, along with the remaining 1 tablespoon of soy sauce, a pinch of salt, and the optional red pepper flakes. Stir-fry everything together for 2-3 minutes until the beef is cooked through and the flavors are well combined.

Step 9

Taste and adjust seasoning with additional salt or pepper, if needed.

Step 10

Remove the stir-fry from heat and garnish with sliced green onions before serving.

Step 11

Serve immediately as a standalone low-carb meal or alongside steamed broccoli or cauliflower rice.
