how to make Crockpot Mongolian Beef
Ingredients :
- 2 pounds flank steak (sliced against the grain)
- 1/2 cup soy sauce (use tamari for gluten-free)
- 1/2 cup brown sugar (coconut sugar works as a substitute)
- 1/4 cup water (helps dissolve the sugar)
- 2 tablespoons cornstarch (mix with cold water for slurry)
- 2 tablespoons vegetable oil (for searing beef)
- 6 cloves garlic (minced)
- 1 teaspoon ginger (minced, fresh or ground)
- 1/2 teaspoon red pepper flakes (adjust for spice preference)
- 4 green onions (chopped, for garnish)
- Cooked rice (for serving)

Directions :
Prepare the Beef: Slice the flank steak against the grain into thin strips, about 1/4-inch thick. This method ensures the meat is tender and easy to chew.
Make the Sauce: In a bowl, mix together the soy sauce, brown sugar, and water until the sugar dissolves. This will be the base of your delicious sauce.
Create the Slurry: In another small bowl, blend the cornstarch with a few tablespoons of cold water until smooth. This slurry will help thicken your sauce later on.
Sear the Beef: Heat the vegetable oil in a skillet over medium-high heat. Add the beef in batches, searing until it’s browned on the outside. This extra step adds a nice depth of flavor to the dish. Once browned, transfer the beef to the crockpot.
Combine Ingredients: In the crockpot with the beef, add the soy sauce mixture, minced garlic, minced ginger, and red pepper flakes. Stir everything together to coat the beef evenly.
Slow Cook: Cover the crockpot and cook on low for 4 to 6 hours or on high for 2 to 3 hours. The beef will become fork-tender as it cooks.
Thicken Sauce: About 30 minutes before serving, stir in the cornstarch slurry you prepared earlier. This will help thicken the sauce to a nice consistency.
Garnish and Serve: Before serving, sprinkle chopped green onions over the beef for a fresh touch. Serve hot over cooked rice for a complete meal.
how to serve Crockpot Mongolian Beef
Crockpot Mongolian Beef is best served hot, directly from the crockpot. Spoon generous portions over bowls of fluffy cooked rice. The rice soaks up the savory sauce, making every bite delicious. You can also serve it with steamed vegetables or a fresh side salad if you want a well-rounded meal. For a little extra crunch, consider adding toasted sesame seeds or crushed peanuts as a garnish.
how to store Crockpot Mongolian Beef
If you have leftovers, store them in an airtight container in the refrigerator. It will last for up to 3 to 4 days. To reheat, simply microwave individual portions or warm it on the stove over low heat until heated through. You can also freeze leftover Mongolian beef for up to 3 months. Just make sure to use freezer-safe containers. When you’re ready to eat, thaw it overnight in the refrigerator and reheat as mentioned above.
tips to make Crockpot Mongolian Beef
- Cutting the Beef: Make sure to slice the flank steak against the grain. This makes the meat more tender and easier to chew.
- Searing the Meat: Don’t skip the searing step! It adds a lot of flavor to the beef and enhances the overall taste of the dish.

variation
You can easily tweak this recipe to suit your dietary needs or preferences. Here are a few ideas:
- Vegetarian Option: Use tofu or seitan instead of beef. Just make sure to press and drain the tofu before cutting it into cubes and cooking.
- Different Cut of Meat: If flank steak isn’t available, you can substitute it with sirloin or chuck roast. Just remember that cooking times may vary slightly based on the cut you use.
- Custom Sauce: Feel free to experiment with the sauce by adding other ingredients. A splash of rice vinegar or Hoisin sauce can give it a different flavor profile.
FAQs
1. Can I make this recipe ahead of time?
Yes! This recipe is perfect for meal prep. You can prepare it a day ahead, let it cool, and store it in the refrigerator. It actually tastes even better the next day as the flavors meld together.
2. Is it possible to cook this on the stove instead of in a crockpot?
Absolutely! You can adapt this recipe for the stove by searing the meat and then simmering everything in a pot. Just make sure to cook it until the beef is tender.
