Ingredients for Slow Cooker Mongolian Beef
- 1 pound flank steak, sliced against the grain
- 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 crushed red pepper flakes (optional)
- 2 tablespoons cornstarch
- 2 green onions, chopped for garnish
- Cooked rice for serving
Step-by-Step Instructions
- Prep the Beef: Start by slicing the flank steak against the grain into thin strips. This technique will ensure the meat remains tender after cooking.
- Mix the Sauce: In a mixing bowl, combine the soy sauce, brown sugar, water, minced garlic, minced ginger, and optional red pepper flakes. Whisk together until well blended.
- Combine in Slow Cooker: Place the sliced beef in the slow cooker and pour the sauce mixture over the top. Give it a gentle stir to ensure the beef is well coated.
- Cook: Cover the slow cooker and set it to cook for 4-5 hours on low or 2-3 hours on high. You’ll know it’s ready when the beef is tender and the sauce is bubbly.
- Thicken the Sauce: About 30 minutes before serving, mix the cornstarch with a couple of tablespoons of cold water to create a slurry. Stir this into the slow cooker. This will thicken the sauce and give it that hearty gloss!
- Finish It Up: When it’s done, serve over freshly cooked rice and garnish with chopped green onions for that pop of color.
Top Tips for Perfecting Slow Cooker Mongolian Beef
- Flank Steak Alternatives: If flank steak seems pricey, you can substitute with sirloin or skirt steak, both of which are still tender and suitable for slow-cooking.
- Don’t Rush the Cook Time: Allowing the beef to cook longer on low heat enhances the flavors and ensures tenderness. Resist the urge to lift the lid!
- Spice It Up: For a little kick, add extra crushed red pepper flakes or even a splash of chili oil when serving.
- Adjust for Sweetness: Feel free to reduce the amount of brown sugar if you prefer a less sweet dish!
Storing and Reheating Tips
Leftovers? No problem! Store your Slow Cooker Mongolian Beef in an airtight container in the refrigerator for up to 3-4 days. If you’d like to keep it longer, it freezes well for up to three months. Simply defrost in the refrigerator before reheating.
To reheat, warm the beef in a saucepan over low heat, adding a splash of water or beef broth to maintain its moisture. You can also pop it in the microwave for quick reheating. Just remember to cover it to prevent splatters!
By making Slow Cooker Mongolian Beef, you’ll not only create a delicious meal but also some lovely memories around the dinner table. So gather your loved ones, serve up this delightful dish, and enjoy a comforting meal together. Happy cooking!
