Ingredients

• For the Beef Marinade:
• 1 lb (450 g) flank steak, thinly sliced against the grain
• 2 tablespoons soy sauce (or coconut aminos for a gluten-free option)
• 1 tablespoon cornstarch (or a low-carb thickener like xanthan gum)
• 1 tablespoon sesame oil
• 1 teaspoon garlic powder
• 1 teaspoon ginger powder
• For the Stir Fry:
• 2 medium zucchini (approximately 12 oz), spiralized into noodles (zoodles)
• 2 tablespoons vegetable oil (or avocado oil)
• 4 cloves garlic, minced
• 1-inch piece fresh ginger, minced
• 1 bell pepper, sliced (red, green, or yellow)
• 1 small onion, thinly sliced
• 3 green onions, chopped (for garnish)
• For the Sauce:
• 1/4 cup soy sauce (or coconut aminos)
• 2 tablespoons brown sugar substitute (like erythritol or monk fruit sweetener)
• 1 tablespoon rice vinegar (or apple cider vinegar)
• 1 teaspoon sesame oil
• 1/4 teaspoon red pepper flakes (optional for heat)

When it comes to preparing this dish, the flank steak stands out as a key ingredient. Its lean yet tender texture makes it perfect for stir-frying, ensuring each bite is juicy and flavorful. When choosing flank steak, look for pieces with a bright color and minimal fat. If you’re in a pinch, sirloin or skirt steak can be good substitutes.

The zoodles, made from spiralized zucchini, not only provide a low-carb alternative to traditional noodles but also add a refreshing crunch. Opt for firm zucchinis that have a vibrant green color for the best results. If you want to mix things up, you can substitute zucchini with yellow squash or even carrot noodles for a sweeter twist.

Finally, the sauce is where the magic happens. Combining soy sauce (or coconut aminos), a brown sugar substitute, and rice vinegar creates a balance of savory and sweet flavors. When selecting a brown sugar substitute, erythritol is a popular choice for its minimal impact on blood sugar levels. If you need a sweeter sauce, you can increase the amount of sweetener to suit your taste.

Step-by-Step Instructions

1. Start by marinating the beef. In a bowl, combine the flank steak, soy sauce, cornstarch, sesame oil, garlic powder, and ginger powder. Mix well to coat the meat. Let it marinate for at least 15 minutes while you prepare the other ingredients.
2. While the beef is marinating, spiralize the zucchini into zoodles. Set them aside on a clean kitchen towel to absorb excess moisture, which will help prevent the dish from becoming soggy.
3. Heat the vegetable oil in a large skillet or wok over medium-high heat. Once the oil is hot and shimmering, add the marinated beef. Cook for 2-3 minutes, stirring frequently, until the beef is browned and cooked through. Avoid overcrowding the pan, as this can steam the meat instead of searing it.
4. Once the beef is cooked, remove it from the pan and set it aside on a plate. In the same skillet, add the minced garlic, minced ginger, sliced bell pepper, and sliced onion. Stir-fry for 2-3 minutes until the vegetables are tender but still slightly crisp. You’ll know they are ready when they start to change color and become fragrant.
5. Next, add the zoodles to the skillet with the sautéed vegetables. Stir-fry for an additional 2-3 minutes. The zoodles should be heated through but still have a slight crunch. Take care not to overcook them, as they can release too much moisture.
6. Return the cooked beef to the pan and add the sauce made from soy sauce, brown sugar substitute, rice vinegar, sesame oil, and red pepper flakes. Stir everything together, cooking for another minute until everything is well-coated and heated through. The sauce should be glossy and thickening slightly.
7. Remove the skillet from heat and garnish your dish with chopped green onions. Serve immediately for the best texture and flavor.

Pro Tips for the Best Low Carb Mongolian Beef Zoodle Stir Fry

• Use a high-quality flank steak for the best flavor and tenderness. Take the time to slice it thinly against the grain to ensure each bite is melt-in-your-mouth.
• A common mistake is overcooking the zoodles. Cook them just until they’re warmed through and still have some bite, as they can become mushy quickly.
• Invest in a good spiralizer if you plan on making zoodles frequently. A sturdy one will give you consistent noodle shapes and make the process much easier.
• To enhance the depth of flavor in the dish, consider adding a splash of sesame oil to the stir-fry just before serving. This will give it an aromatic finish.
• If you prefer a thicker sauce, let it simmer for an extra minute or two before tossing it with the beef and zoodles. This will help it cling better to the ingredients.

Variations & Serving Ideas

• For a spicy twist, add sliced jalapeños or additional red pepper flakes to the stir-fry.
• Try substituting the flank steak with chicken or shrimp for a different protein option, while keeping the flavors consistent.
• Incorporate seasonal vegetables, such as snap peas or broccoli, for extra nutrition and color.
• For a vegetarian version, use tofu instead of beef and adjust the cooking time accordingly.

When it comes to serving suggestions, this dish pairs beautifully with cauliflower rice for an extra low-carb option, allowing you to soak up all the delicious sauce. A side of steamed broccoli adds a nice crunch and complements the flavors well. If you’re looking for something refreshing, a simple cucumber salad with a light vinaigrette can balance out the richness of the beef stir fry.

Storage, Make-Ahead & Reheating

For optimal freshness, store the Low Carb Mongolian Beef Zoodle Stir Fry in an airtight container in the fridge for up to 3 days. It does not freeze well due to the texture of the zoodles, which can become mushy upon thawing. When you’re ready to enjoy leftovers, simply reheat in a skillet over medium heat for about 5-7 minutes, or until heated through. Interestingly, many find that the dish tastes even better the next day, as the flavors have more time to meld together.
