Ingredients
  

  • 1.5 pounds beef (flank steak, skirt steak, or sirloin), thinly sliced against the grain
  • 4 cups broccoli florets (about 2 medium heads), cut into bite-sized pieces
  • 2 tablespoons avocado oil (or other high-heat oil)
  • 4 cloves garlic, minced
  • 1 tablespoon fresh ginger, grated (or 1 teaspoon ground ginger)
  • 1/2 teaspoon red pepper flakes (optional, for heat)
  • 1/3 cup tamari (gluten-free soy sauce) or coconut aminos
  • 1/3 cup beef broth (or water)
  • 1–1.5 tablespoons granulated erythritol or allulose (adjust to taste)
  • 1 tablespoon toasted sesame oil
  • 1 teaspoon fish sauce (optional, for umami depth)
  • 1 teaspoon rice vinegar (or apple cider vinegar)
  • 1/2 teaspoon xanthan gum (optional, for thickening)
  • Cauliflower rice, about 4 cups cooked, for 4 portions
  • Sesame seeds and scallions, sliced, for garnish
  • 4–5 meal prep containers, microwave-safe with tight lids

Method
 

  1. Prep the beef: Pat the steak dry. Slice thinly against the grain for tenderness. If time allows, pop it in the freezer for 15 minutes first—it makes slicing easier.
  2. Mix the sauce: In a bowl, whisk tamari, beef broth, sweetener, sesame oil, fish sauce, and vinegar. If using xanthan gum, sprinkle it in while whisking until fully dissolved. Set aside.
  3. Blanch or steam the broccoli: For crisp-tender results, steam or blanch for 2–3 minutes until bright green. Drain well and pat dry to avoid watering down the sauce.
  4. Sear the beef: Heat 1 tablespoon avocado oil in a large skillet or wok over high heat. Add half the beef in a single layer. Sear 60–90 seconds per side until browned but still pink in the center. Transfer to a plate. Repeat with remaining oil and beef.
  5. Sauté aromatics: Lower heat to medium. Add garlic, ginger, and red pepper flakes. Stir for 30 seconds until fragrant. Don’t burn the garlic.
  6. Build the sauce: Pour in the sauce. Simmer 1–2 minutes to thicken slightly. If not using xanthan gum, reduce a bit longer to concentrate.
  7. Combine: Return the beef and any juices to the pan. Add broccoli. Toss to coat and warm through, 1–2 minutes. Taste and adjust salt, sweetener, or vinegar as needed.
  8. Prepare the base: While the pan works, cook cauliflower rice in a separate skillet with a little oil and salt until tender and lightly golden, 5–7 minutes. Keep it dry, not soggy.
  9. Assemble: Divide cauliflower rice among containers. Top with beef and broccoli. Sprinkle sesame seeds and scallions.
  10. Cool and store: Let containers cool uncovered 15–20 minutes before sealing. Label and refrigerate.
