Slow Cooker Mongolian Beef Ingredients

Every ingredient in Slow Cooker Mongolian Beef plays a crucial role in building the dish’s flavor and texture. From the tender beef to the savory sauce, these ingredients complement each other beautifully and are what make this recipe irresistible. Here are the key players you’ll need:

- 2 tablespoons olive oil: Adds richness and helps in browning the beef.
- 1 teaspoon garlic, minced: Adds a depth of flavor that enhances the overall taste of the dish.
- ¾ cup soy sauce: Provides a savory, umami flavor and is a key component of the sauce.

Step by Step Guide for Slow Cooker Mongolian Beef

Now that you have your ingredients ready, let’s dive into making Slow Cooker Mongolian Beef. This recipe is straightforward, making it perfect for cooks of all skill levels. Follow these detailed steps to create a dish that will leave everyone asking for seconds.
- Start by cutting the flank steak into thin strips. Aim for about half an inch thick to ensure even cooking. The thinner the strips, the more tender they become during the slow cooking process.
- Next, place the beef strips in a ziplock bag and add the cornstarch. Seal the bag and shake it well until all the pieces are evenly coated. This step is crucial as it creates a lovely crust when cooked.
- In a medium-sized bowl, combine the olive oil, garlic, soy sauce, water, and brown sugar. Whisk these ingredients together until the sugar dissolves completely, creating a smooth sauce.
- Pour this sauce into your slow cooker. It’s the base that will enhance the flavors of the beef as it cooks.
- Add the coated flank steak and grated carrots to the slow cooker. Stir well to ensure that all the meat and carrots are coated in the sauce.
- Now, cover your slow cooker and set it to high. Let it cook for about 2 to 3 hours. Alternatively, you can set it to low and cook for 4 to 5 hours, depending on your schedule.
- As it cooks, the beef will become tender, and the flavors will meld beautifully. Keep an eye on it and enjoy the delicious aroma wafting through your home!
- Once cooking is complete, give it a good stir. The sauce should be thickened, and the beef should be fork-tender.
- Serve the Slow Cooker Mongolian Beef over a bed of rice for a complete meal. Top it off with chopped green onions and a sprinkle of sesame seeds for added flavor and crunch.
- Enjoy your meal and get ready for compliments from family and friends!
Things Worth Knowing
- Slow cooking magic: Cooking at low temperatures allows the beef to break down, resulting in tender meat that’s full of flavor.
- Don’t skip the cornstarch: Coating the meat with cornstarch not only thickens the sauce but also keeps the beef juicy during cooking.
- Timing is key: Make sure to adjust cooking times based on your slow cooker settings. Each cooker varies slightly.
- Flavor boost: Letting the beef marinate in the sauce for a few hours before cooking can enhance the flavors even more.
