Step-by-Step Instructions

Prepare the Beef

Slice the flank steak or sirloin thinly against the grain. This ensures the beef stays tender when cooked. Set aside.

Blanch the Broccoli

Bring a pot of water to a boil and add the broccoli florets. Let them cook for about 2-3 minutes until bright green and slightly tender but still crisp.

Drain and set aside.

Make the Stir-Fry Sauce

In a small bowl, combine low-sodium soy sauce (or tamari for gluten-free), sesame oil, beef broth, minced garlic, ginger, and erythritol (or stevia) for a hint of sweetness.

Stir until the sweetener is fully dissolved and the mixture is well combined. Add red pepper flakes if you prefer a spicy kick.

Cook the Beef

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

Add the thinly sliced beef and stir-fry for about 3-4 minutes until browned and cooked through.

Remove the beef from the pan and set aside.

Stir-Fry the Broccoli

In the same skillet, add another tablespoon of avocado oil if needed.

Toss in the blanched broccoli and cook for another 2-3 minutes, allowing the broccoli to soak up the flavors of the pan.

Combine the Beef and Broccoli

Add the cooked beef back into the skillet with the broccoli.

Pour the stir-fry sauce over the top and toss everything together to coat evenly.

Cook for an additional 1-2 minutes to ensure everything is heated through and the sauce slightly thickens.

Serve

Once everything is well combined and heated, remove from heat and serve immediately.

What to Serve with Keto Beef and Broccoli Stir-Fry

To complete your meal, pair this Keto Beef and Broccoli Stir-Fry with a keto-friendly side dish such as:

  • Cauliflower Rice: Light and fluffy cauliflower rice is an excellent substitute for regular rice and perfectly complements the stir-fry.
  • Zucchini Noodles: If you’re craving noodles, spiralized zucchini noodles are a fantastic low-carb alternative.
  • Shirataki Noodles: These zero-calorie, keto-friendly noodles are another great option if you miss traditional noodles.
  • Keto-Friendly Mashed Cauliflower: For a comforting, creamy side that’s low in carbs, try mashed cauliflower instead of mashed potatoes.
  • Avocado Salad: A fresh side salad with sliced avocado, cucumbers, and a simple olive oil dressing can enhance the flavors of this stir-fry.
