Why This Keto Mongolian Beef Stands Out

Keto Mongolian Beef is more than just a meal; it’s a celebration of flavors and textures that will transport your taste buds to the bustling streets of Mongolia. By swapping out traditional high-carb ingredients for keto-friendly alternatives, this recipe allows you to enjoy the classic taste without the guilt. The use of tender cuts of beef ensures every bite is filled with flavor, while the vibrant veggies add a pop of color and crunch. This dish is not only quick to prepare but also perfect for a weeknight dinner or a meal prep option for the week ahead.

The Ingredient Lineup

1 lb flat iron steak, flank steak, or sirloin (fat removed, 450g) – Choose a tender cut for the best results.
Salt and black pepper – Essential for seasoning your beef to enhance its natural flavors.
2 tablespoons light olive oil or avocado oil – For frying; both oils have a high smoke point.
1 tablespoon fresh ginger, minced – Adds a warm spice that complements the beef beautifully.
3 cloves garlic, minced – A must for that aromatic flavor profile.
1 teaspoon red pepper flakes or chili flakes – For a touch of heat that balances the sweetness.
½ cup tamari or medium soy sauce or coconut aminos (80ml) – Use tamari for a gluten-free option or coconut aminos for a soy-free choice.
½ cup water (60ml) – To help create the sauce.
2 tablespoons brown erythritol – A keto-friendly sweetener that mimics the taste of brown sugar; adjust to taste.
1 red bell pepper, sliced (110g) – Adds sweetness and color.
2 large spring onions, finely sliced (50g) – For garnish and an extra crunch.
1 teaspoon toasted sesame seeds – Optional, for garnish and added flavor.
Drizzle of toasted sesame oil – Optional, but it adds a rich, nutty flavor.

The Method for Keto Mongolian Beef

Step 1: Prepare the Beef

Begin by slicing the beef against the grain into thin strips. This technique ensures tenderness. Season the strips generously with salt and black pepper.

Step 2: Heat the Oil

In a large skillet or wok, heat the light olive oil or avocado oil over medium-high heat. Allow the oil to get hot but not smoking.

Step 3: Cook the Beef

Add the sliced beef to the skillet in a single layer. Avoid overcrowding the pan; you may need to cook in batches. Sear the beef for about 2-3 minutes until browned, then flip and cook for an additional 2-3 minutes. Remove the beef from the skillet and set it aside.

Step 4: Sauté the Aromatics

In the same skillet, add the minced ginger and garlic. Sauté for about 30 seconds until fragrant, being careful not to burn them.

Step 5: Create the Sauce

Add the red pepper flakes, tamari or soy sauce, water, and brown erythritol to the skillet. Stir to combine, scraping any browned bits from the bottom of the pan for added flavor. Let the mixture simmer for about 2-3 minutes.

Step 6: Add the Vegetables

Stir in the sliced red bell pepper and cook for another 2-3 minutes until the peppers are tender but still crisp.

Step 7: Combine the Beef and Sauce

Return the cooked beef to the skillet, tossing it well to coat it in the sauce and heat it through. The sauce should thicken slightly.

Step 8: Garnish and Serve

Remove the skillet from the heat. Serve the Keto Mongolian Beef hot, garnished with finely sliced spring onions and a sprinkle of toasted sesame seeds. Drizzle with toasted sesame oil if desired for an extra layer of flavor.
