Step-by-Step Instructions
1. Prepare the Beef
In a medium bowl, combine the sliced flank steak with 2 tablespoons of soy sauce, 1 tablespoon of sesame oil, and cornstarch. Toss to coat evenly and let it marinate for at least 10 minutes while you prepare other ingredients.
2. Whisk the Stir-Fry Sauce
In a small bowl, whisk together the 1/4 cup soy sauce, rice vinegar, 1 tablespoon sesame oil, sweetener, ginger, minced garlic, and red pepper flakes (if using). Set this sauce aside.
3. Cook the Broccoli
Heat 1 tablespoon of olive oil in a large skillet or wok over medium-high heat. Add the broccoli florets and stir-fry for 3-5 minutes until they are bright green and slightly tender-crisp. Remove the broccoli from the pan and set it aside.
4. Cook the Beef
Add the remaining 1 tablespoon of olive oil to the same skillet. Increase the heat to high. Once hot, add the marinated beef in a single layer and cook for 2-3 minutes per side, until browned and cooked through. Avoid overcrowding the pan; you might need to cook the beef in batches.
5. Combine and Serve
Return the cooked broccoli to the skillet with the beef. Pour the stir-fry sauce over everything. Toss gently to coat all ingredients and cook for another 1-2 minutes, allowing the sauce to thicken slightly. Serve your delicious low carb dinner immediately.
Variation Ideas
- Add sliced bell peppers or mushrooms for extra vegetables.
- Sprinkle with sesame seeds or chopped green onions before serving.
- Serve over cauliflower rice for another low carb option.
Storage Instructions
You can store leftover Beef and Broccoli Stir-Fry in an airtight container in the refrigerator for up to 3-4 days. To reheat, warm it gently in a skillet over medium heat or in the microwave until heated through. Be careful not to overcook the beef when reheating.
Frequently Asked Questions
