How to Make Keto Low Carb Beef And Broccoli

Creating this delicious meal is simple! Follow these steps to prepare your dish:

  1. Start by thinly slicing your flat iron steak against the grain. This technique ensures tenderness in every bite.
  2. Place the sliced beef in a small bag or bowl. Add the coconut aminos, garlic, and grated ginger. Let this mixture marinate in the refrigerator for about 1 hour, allowing the flavors to meld together beautifully.
  3. While the beef marinates, bring a pot of water to boil. Blanch your broccoli florets for about 2 minutes, then drain them well to avoid excess moisture.
  4. In a large wok or cast iron skillet, heat the coconut oil over medium-high heat. Stir-fry the marinated beef for approximately 1 to 3 minutes or until it is browned. Remove the beef from the skillet and set it aside.
  5. Add the blanched broccoli to the skillet and stir-fry for about 3 minutes until it is crisp-tender. After that, pour in the reserved marinade and cook for an additional 2 minutes to thicken the sauce.
  6. Finally, return the beef to the skillet with the broccoli, warming it thoroughly. Drizzle with fish sauce and toasted sesame oil, then serve immediately.

Serving Suggestions

This dish is delicious on its own, but consider pairing it with:

Storage, Freezing, and Reheating

Leftovers can be stored in an airtight container in your refrigerator for up to 3 days. If you’d like to keep it longer, you can freeze the beef and broccoli for up to 2 months. When it’s time to reheat, warm it in a skillet over medium heat until heated through; be careful not to overcook the broccoli to maintain its texture.

Frequently Asked Questions

Can I use frozen broccoli for this recipe?

Yes, frozen broccoli can be a convenient substitute. Just make sure to thaw it first and drain any excess moisture to maintain the best texture in the dish!

How long should I marinate the beef?

For optimal flavor, marinate the beef for at least 1 hour. If your schedule allows, marinating overnight can even enhance the taste.

What if I don’t have coconut aminos?

In that case, Tamari or low-sodium soy sauce may be used, but adjust the quantities because these alternatives tend to be saltier than coconut aminos.

Can I use other cuts of beef?

Absolutely! Cuts like flank steak and sirloin work well. Remember to slice against the grain for tenderness.

Is this meal prep-friendly?

Definitely! This recipe is great for meal prepping; simply store portioned servings in containers, and you can easily heat them up for quick meals later in the week.

Notes

Use only root ginger; this is not interchangeable with powdered ginger. Make sure to drain the broccoli well after blanching to prevent excess moisture in the stir fry. Serve fresh for the best texture and flavor. For a thicker sauce, consider adding a small amount of arrowroot or cornstarch mixed with water at the end of the cooking process.
