Ingredients:
- 2 pounds flank steak, sliced thinly
- 1/2 cup soy sauce
- 1/2 cup brown sugar
- 1/4 cup water
- 1 tablespoon minced garlic
- 1 tablespoon minced ginger
- 1/4 teaspoon red pepper flakes
- 1 tablespoon cornstarch
- 2 tablespoons vegetable oil
- 2 green onions, chopped
- Steamed rice or vegetables for serving
Method:
Step 1: Make the Flavorful Sauce
In a bowl, mix soy sauce, brown sugar, water, garlic, ginger, and red pepper flakes. Set aside to let the flavors meld.
Step 2: Sear the Beef
In a skillet, heat vegetable oil over medium-high heat. Sear the beef slices until browned on both sides, giving them a delightful crust and depth of flavor.
Step 3: Combine Beef and Sauce
Place the seared beef in a slow cooker and pour the prepared sauce over it, ensuring all the meat is coated.
Step 4: Slow Cook to Perfection
Cover and cook on low for 5-6 hours or on high for 3-4 hours, allowing the flavors to infuse and the beef to become tender.
Step 5: Thicken the Sauce
About 30 minutes before serving, mix cornstarch with a bit of water to create a slurry. Stir this into the slow cooker to thicken the sauce, giving it a glossy finish.
Step 6: Serve and Garnish
Serve over steamed rice or with fresh vegetables, garnished with chopped green onions for a pop of color and flavor.
Serving Suggestions & Pairings
Mongolian Beef shines when served over a bed of fluffy steamed rice, which absorbs the delicious sauce beautifully. For a healthier twist, try it with sautéed broccoli or snap peas for a colorful plate. A side of spring rolls or a crisp Asian salad can make for an exquisite meal spread.
Storage & Leftovers Guide
If you find yourself with leftovers, don’t worry! Store the cooled Mongolian Beef in an airtight container in the fridge for up to 3 days. To reheat, simply warm it gently on the stove or in the microwave. It also freezes well for up to 2 months; just thaw it overnight in the fridge before reheating.
Kitchen Wisdom & Success Tips
- Choosing the Right Cut: Flank steak is ideal because of its tenderness when slow-cooked. Make sure to slice it thinly against the grain for the best texture.
- Flavor Boost: Feel free to add a splash of rice vinegar or sesame oil to the sauce for an extra layer of flavor.
- Keep It Low and Slow: For the most tender beef, opt for the low cooking setting if you have the time.
- Cornstarch Alternatives: If you run out of cornstarch, you can use flour or arrowroot powder in a pinch, but adjust the amount accordingly.
- Make it Your Own: Add in sliced bell peppers or carrots during the last hour of cooking for more veggies and color.
Flavor Variations & Adaptations
Love a bit of heat? Increase the red pepper flakes or add some sliced chili peppers. For a sweeter version, add more brown sugar or drizzle honey into the sauce. Are you a fan of nuts? Toss in some toasted sesame seeds or crushed peanuts as a garnish!
