Ingredients

Instructions

  1. Step 1: Slice 8 oz flank steak thinly against the grain. Heat 1 tbsp avocado oil in a wok over high heat until smoking, then add steak and cook for 2-3 minutes per side until browned; remove and set aside.
  2. Step 2: Add remaining 1 tbsp avocado oil to the wok, then add minced garlic and grated ginger. Sauté for 30 seconds until fragrant, then add 2 cups broccoli florets and stir-fry for 4-5 minutes until bright green and crisp-tender.
  3. Step 3: Return steak to the wok, add 1/4 cup coconut aminos, 1 tbsp rice vinegar, and 1/4 tsp red pepper flakes. Simmer for 2 minutes until sauce thickens and coats ingredients, then drizzle with 1 tbsp sesame oil.

How do I scale Beef and Broccoli Stir-Fry with Keto Sauce for a different number of people?
