Ingredients

For the Beef & Broccoli

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

• 3 cups broccoli florets (fresh or frozen, thawed)

• 2 tablespoons avocado oil or olive oil

• Salt and pepper to taste

For the Keto Stir-Fry Sauce

• 1/4 cup coconut aminos (or tamari for gluten-free keto)

• 1 tablespoon sesame oil

• 2 tablespoons water

• 1 tablespoon rice vinegar (unsweetened)

• 1 tablespoon erythritol or monk fruit sweetener

• 1 teaspoon xanthan gum (for thickening, optional)

• 3 garlic cloves, minced

• 1 teaspoon fresh ginger, grated

• 1/4 teaspoon red pepper flakes (optional for heat)

Instructions

Step 1: Prepare the Beef

1. Slice the steak thinly against the grain to ensure tenderness. Pat dry using paper towels.

2. Season lightly with salt and pepper. Optionally, marinate in 1 tablespoon coconut aminos for 10 minutes to deepen flavor.

Step 2: Make the Sauce

1. In a small bowl, combine coconut aminos, sesame oil, rice vinegar, water, erythritol, garlic, ginger, and red pepper flakes.

2. Stir in xanthan gum if you prefer a thicker sauce. Set aside.

Step 3: Sear the Beef

1. Heat 1 tablespoon avocado oil in a large skillet or wok over medium-high heat.

2. Add the beef slices in a single layer (in batches if needed) and sear for about 2-3 minutes per side until browned. Avoid overcooking to keep beef tender.

3. Remove cooked beef and set aside.

Step 4: Cook the Broccoli

1. In the same skillet, add 1 tablespoon oil if needed.

2. Toss in the broccoli and stir-fry for 3–4 minutes until bright green and crisp-tender. Add 1–2 tablespoons of water to help steam the broccoli if necessary.

Step 5: Combine & Simmer

1. Return the cooked beef to the skillet with the broccoli.

2. Pour the prepared keto sauce over the beef and broccoli.

3. Toss everything well and simmer for 2–3 minutes, allowing the sauce to thicken and coat all ingredients.

Step 6: Rest and Serve

1. Let the dish rest off-heat for about 5 minutes to allow the flavors to meld and sauce to settle.

2. Serve hot, optionally topped with sesame seeds or sliced green onions.

Tips & Variations

• Vegetable Add-Ons: Add bell peppers, zucchini, or mushrooms to increase the veggie volume.

• For Extra Flavor: Add a dash of fish sauce or toasted sesame seeds to the final dish.

• Low-Carb Sides: Serve with cauliflower rice or shirataki noodles for a more filling keto meal.

Why This Recipe Works for Keto

This Keto Beef & Broccoli Recipe maintains low carbohydrate content by avoiding traditional ingredients like corn starch, sugar, and soy sauce with added sugars. Instead, we use keto-friendly substitutes such as coconut aminos, erythritol, and xanthan gum to deliver the same rich umami flavor and glossy stir-fry finish without the blood sugar spike.

Broccoli is a fantastic keto-approved vegetable that’s high in fiber, vitamin C, and antioxidants, while beef provides a healthy dose of protein and essential nutrients like iron and B vitamins. The balanced macros make this dish excellent for those on a ketogenic diet looking to maintain energy and satiety.

Meal Prep & Storage Tips

• Meal Prep: Slice the beef and pre-mix the sauce in advance to cut down cooking time.

• Storage: Refrigerate leftovers in an airtight container for up to 3 days.

• Reheat: Gently reheat in a skillet or microwave, adding a splash of water to revive the sauce.

• Freezing: Freeze cooked portions for up to 2 months. Thaw overnight and reheat before serving.
