How to Make Ultimate Slow Cooker Mongolian Beef for Busy Weeknights

Step 1: Prepare the Beef

Slice your beef thinly against the grain for maximum tenderness. This helps it cook evenly and soak up all the wonderful flavors of the sauce during the slow cooking process.

Step 2: Create the Sauce Mixture

In a bowl, combine soy sauce, brown sugar, minced garlic, ginger, and water or beef broth. Stir until the sugar dissolves completely, making the sweet-savory base that defines Mongolian beef.

Step 3: Layer Ingredients in the Slow Cooker

Place the beef slices at the bottom of your slow cooker, then pour the sauce mixture evenly over the top. Sprinkle chopped green onions over it for added flavor and aroma while it cooks.

Step 4: Slow Cook to Perfection

Cover and cook on low for 4 to 6 hours or on high for 2 to 3 hours, until the beef is tender and the sauce has thickened. Stir once halfway through cooking to ensure even flavor distribution.

Step 5: Thicken the Sauce

About 30 minutes before serving, mix cornstarch with a little cold water to make a slurry and stir it into the slow cooker. Let it cook uncovered until the sauce reaches that beautiful, glossy thickness.

Pro Tips for Making Ultimate Slow Cooker Mongolian Beef for Busy Weeknights

• Add Sauce Ingredients Fresh: Fresh garlic and ginger truly make the flavors pop.
• Use a Slow Cooker Liner: Saves cleanup time and prevents sticking or burning on the bottom.
• Timing Matters: Cooking too long can dry out the beef, so stick to recommended slow cooker times.
