Ingredients

1 pound flank steak, sliced against the grain
1 tablespoon fresh grated ginger
3 cloves fresh minced garlic
1/2 cup quality soy sauce
1/4 cup brown sugar (or coconut sugar for a healthier option)
2 tablespoons sesame oil
2 tablespoons cornstarch (or arrowroot powder for gluten-free option)
2 tablespoons chopped green onions

Instructions

Step 1: Slice the flank steak against the grain into thin strips about ¼ inch thick. This helps keep the beef tender after cooking.
Step 2: In a large mixing bowl, combine the sliced beef with grated ginger, minced garlic, soy sauce, brown sugar, and sesame oil. Mix well to ensure the meat is evenly coated.
Step 3: Pour the marinated beef mixture into your slow cooker, spreading it out evenly for consistent cooking.
Step 4: Set your slow cooker to low and cook the beef for 6 to 7 hours, or use the high setting for 3 to 4 hours. The beef will become tender and flavorful.
Step 5: About 30 minutes before serving, whisk the cornstarch with a small amount of water to make a slurry. Stir this into the slow cooker to thicken the sauce.
Step 6: Once cooking is complete, carefully plate the beef, drizzle extra sauce on top, and garnish with chopped green onions for a fresh finish.

Tips & Variations

For a gluten-free version, substitute soy sauce with tamari and use arrowroot powder instead of cornstarch.
Serve over steamed rice or cauliflower rice for a complete meal.
Add sliced bell peppers or broccoli to the slow cooker for extra veggies and color.
Marinate the beef for an hour before cooking if you want even deeper flavor.

Storage

Store leftover Mongolian beef in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over medium heat or in the microwave until warmed through. Avoid overcooking when reheating to keep the beef tender.

FAQs

Can I use a different cut of beef for this recipe?

Flank steak is best because it becomes very tender when slow-cooked, but you can also use skirt steak or sirloin. Just be sure to slice against the grain and watch cooking times to avoid toughness.

Is it necessary to thicken the sauce with cornstarch?

Thickening the sauce creates a nice, glossy finish and helps the flavors cling to the beef. If you prefer a thinner sauce, you can skip this step, but the texture will be different.
