📝 Ingredients (Serves 4)

For the Beef & Broccoli:

• 1 lb (450g) flank steak or sirloin, thinly sliced against the grain

• 4 cups fresh broccoli florets

• 2 tablespoons avocado oil (or sesame oil)

• 3 cloves garlic, minced

• 1 teaspoon fresh grated ginger

• Salt & black pepper to taste

For the Keto Stir Fry Sauce:

• 1/3 cup coconut aminos (or gluten-free tamari for fewer carbs)

• 1 tablespoon soy sauce (optional for deeper flavor)

• 1 tablespoon sesame oil

• 1 tablespoon rice vinegar

• 1 teaspoon keto brown sugar substitute (erythritol/monk fruit blend)

• 1/4 teaspoon red pepper flakes (optional)

• 1/2 teaspoon xanthan gum (for thickening)

• 1/4 cup beef broth

🔪 Preparation Tips (Highly Recommended)

✔ Slice Beef Properly

Freeze the steak for 15–20 minutes before slicing — this makes it easier to cut very thin strips. Always slice against the grain for maximum tenderness.

✔ Don’t Overcrowd the Pan

Cook beef in batches if needed. Overcrowding causes steaming instead of searing.

✔ Prep Everything First

Stir fry moves fast — have all ingredients chopped and sauce mixed before heating the pan.

👩‍🍳 Step-by-Step Instructions

1️⃣ Make the Sauce

In a small bowl, whisk together coconut aminos, soy sauce, sesame oil, rice vinegar, sweetener, red pepper flakes, and beef broth. Sprinkle xanthan gum slowly while whisking to avoid clumping. Set aside.

2️⃣ Cook the Broccoli

Heat 1 tablespoon oil in a large skillet or wok over medium-high heat.
Add broccoli and stir fry for 3–4 minutes until bright green but still crisp.
Remove from pan and set aside.

Tip: If you prefer softer broccoli, add 1–2 tablespoons water and cover for 1 minute to lightly steam.

3️⃣ Sear the Beef

Add remaining oil to the same pan.
Spread beef in a single layer and cook 1–2 minutes per side until browned.
Avoid moving it too much to get a nice sear.

Add garlic and ginger in the last 30 seconds and stir until fragrant.

4️⃣ Combine & Thicken

Return broccoli to the pan.
Pour in prepared sauce and stir well.
Let simmer 2–3 minutes until sauce thickens and coats everything beautifully.

Taste and adjust salt or sweetness if needed.

💡 Pro Tips for Best Results

• Use high heat for authentic stir fry texture

• A cast iron skillet works great if you don’t have a wok

• For ultra-tender beef, marinate slices in 1 teaspoon baking soda + 1 tablespoon water for 15 minutes, then rinse and pat dry before cooking
