Step‑by‑Step Instructions for Slow Cooker Mongolian Beef

Step 1: Prepare the Beef
Begin by slicing your flank steak thinly against the grain, which helps ensure tenderness. Aim for pieces about 1/4 inch thick. Place the sliced beef into a large bowl and set it aside as you prepare the delicious sauce that will elevate your Slow Cooker Mongolian Beef.

Step 2: Make the Sauce
In a separate bowl, mix together soy sauce, brown sugar, minced garlic, minced ginger, and cornstarch. Stir until the mixture is well combined and the brown sugar has dissolved. This sauce is the heart of your Slow Cooker Mongolian Beef, giving it that rich, savory flavor we all love.

Step 3: Combine in the Slow Cooker
Pour the sauce mixture over the sliced beef in the bowl, tossing to ensure all pieces are evenly coated. Transfer everything into the slow cooker, spreading the beef evenly for optimal heat distribution. This preparation is crucial for an even cooking process, helping the flavors meld perfectly.

Step 4: Cook Low and Slow
Cover the slow cooker and set it to low. Allow the beef to cook for 3 hours, stirring occasionally. The meat should turn tender and soak up the sauce, creating a glossy appearance. Keep an eye on it toward the end to prevent overcooking, ensuring your Slow Cooker Mongolian Beef stays moist and flavorful.

Step 5: Adjust Seasoning
After the cooking time is up, use a spoon to taste the sauce. If needed, adjust the seasoning with more soy sauce or sugar based on your preference. This step personalizes your Slow Cooker Mongolian Beef, allowing you to balance the sweet and savory components for your family’s taste.

Step 6: Serve and Enjoy
Once satisfied with the flavor, serve the Slow Cooker Mongolian Beef over a bed of fluffy rice or noodles. The beef should be tender with a rich, sticky sauce that clings to each piece. For a finishing touch, consider garnishing with sliced green onions or sesame seeds to enhance both flavor and presentation.

Slow Cooker Mongolian Beef Recipe FAQs

How do I choose the right flank steak?
Absolutely! When selecting flank steak, look for a cut that is bright red with minimal dark spots. The meat should be firm to the touch and have a good amount of marbling for maximum tenderness. If flank steak isn’t available, sirloin or chuck roast can serve as great alternatives, each bringing its unique texture and flavor to your dish.

How should I store leftovers?
Store any leftover Slow Cooker Mongolian Beef in an airtight container in the refrigerator for up to 3-4 days. I recommend allowing it to cool to room temperature before sealing to maintain freshness. If you’d like to keep it longer, transfer it to the freezer where it can last for up to 2-3 months! Just remember to label your container with the date for reference.

Can I freeze Slow Cooker Mongolian Beef?
Absolutely! Freezing is a great way to preserve your delicious meal. First, let your dish cool completely. Then, pour the beef into a freezer-safe bag or container and squeeze out excess air. When you’re ready to eat, simply thaw it overnight in the fridge, then reheat on the stove. If it appears a bit dry after freezing, adding a splash of beef broth while reheating will restore its delicious moisture.

What if my sauce is too thick?
If you find your sauce has thickened too much while cooking, don’t fret! You can simply add a little broth or water, about a tablespoon at a time, stirring until you reach your desired consistency. This will help bring balance back to the sauce, ensuring each bite of your Slow Cooker Mongolian Beef remains juicy and flavorful.

Are there any dietary considerations for this recipe?
Very! If anyone in your family has gluten sensitivities, swapping regular soy sauce for a gluten-free version is a simple adjustment. Additionally, if you’re looking to reduce sugar intake, consider replacing brown sugar with honey or coconut sugar for a healthier alternative. For pet owners, it’s best to keep the dish away from dogs, as soy sauce and garlic can be harmful to them. Always ensure your ingredients are suitable for everyone at the table!
