What Ingredients You Will Need

This crockpot Mongolian beef recipe uses simple and approachable ingredients that come together to create an incredible dish. Here’s everything you’ll need:

• Beef: 1 ½ pounds of flank steak, thinly sliced against the grain.
• Cornstarch: ¼ cup (helps thicken the sauce and gives the beef a velvety coating).
• Soy sauce: ½ cup (I recommend low-sodium soy sauce to keep the flavors balanced).
• Brown sugar: ⅓ cup (for that signature sweetness).
• Garlic: 3 cloves, minced (fresh garlic works best for bold flavor).
• Ginger: 1 teaspoon, grated (adds warmth and depth to the dish).
• Hoisin sauce: 2 tablespoons (for richness and complexity).
• Sesame oil: 1 tablespoon (optional, but adds a lovely nutty aroma).
• Water: ½ cup (thins out the sauce to the perfect consistency).
• Green onions: 2 stalks, sliced (for garnish and freshness).
• Red pepper flakes: ½ teaspoon (optional, for a little heat).

If you don’t have flank steak, you can substitute with skirt steak or even thinly sliced sirloin. For a gluten-free option, use tamari instead of soy sauce. Feel free to adjust the sweetness or spice level to match your preferences!

Equipment Needed

You don’t need much to make this recipe, which is part of the beauty of it. Here’s what you’ll need:

• Crockpot: A 4-quart or larger crockpot works best for this recipe.
• Knife: A sharp knife for thinly slicing the beef.
• Cutting board: For prepping the beef and veggies.
• Measuring cups and spoons: To ensure the perfect balance of flavors.
• Tongs: For easily handling the cooked beef.

If you don’t have a crockpot, a large Dutch oven can work as an alternative. Just keep an eye on the cooking time and use a low heat setting for a slow simmer.

Preparation Method

1. Prepare the beef: Slice the flank steak thinly against the grain. This ensures the beef is tender and easy to chew. Toss the slices in the cornstarch until evenly coated and set aside.
2. Make the sauce: In a bowl, whisk together the soy sauce, brown sugar, minced garlic, grated ginger, hoisin sauce, sesame oil, and water until well combined.
3. Layer the crockpot: Lightly grease the bottom of your crockpot. Place the coated beef slices inside, spreading them out evenly.
4. Add the sauce: Pour the prepared sauce over the beef, ensuring all the slices are coated. Sprinkle the red pepper flakes if you’re using them.
5. Cook: Set the crockpot to low and cook for 4-5 hours, or until the beef is incredibly tender and the sauce has thickened. If you’re short on time, you can cook on high for 2-3 hours.
6. Garnish: Once cooked, stir the beef to coat it fully in the sauce. Serve hot, garnished with sliced green onions.

Pro tip: If the sauce seems too thin for your liking, mix 1 tablespoon of cornstarch with 2 tablespoons of water and stir it into the crockpot during the last 30 minutes of cooking.

Cooking Tips & Techniques

Here are some tried-and-true tips to make your Mongolian beef even better:

• Slice the beef thin: The thinner the slices, the more tender the beef will be. Freezing the steak for 15-20 minutes beforehand makes slicing much easier.
• Don’t overcook: While the crockpot is forgiving, overcooking can lead to dry beef. Stick to the recommended cooking times for the best texture.
• Balance the flavors: Taste the sauce before adding it to the crockpot. Adjust sweetness or saltiness by tweaking the brown sugar or soy sauce.
• Experiment with veggies: Add bell peppers, broccoli, or snap peas during the last hour of cooking for extra nutrition and color.

Trust me, once you get these techniques down, your Mongolian beef will be foolproof and consistently delicious!

Variations & Adaptations

This recipe is versatile and easy to customize. Here are some ideas to try:

• Gluten-free: Swap soy sauce with tamari or coconut aminos for a gluten-free version without sacrificing flavor.
• Spicy kick: Add more red pepper flakes or a dash of sriracha for an extra spicy twist.
• Vegetarian option: Replace the beef with firm tofu or jackfruit. Cook for less time to maintain the texture.
• Low-carb: Serve the Mongolian beef over cauliflower rice instead of traditional rice.

One variation I tried was adding pineapple chunks during the last hour of cooking—trust me, it was a hit with my family!

Serving & Storage Suggestions

This Mongolian beef is best served hot and fresh over steamed white rice or noodles. For a low-carb option, pair it with cauliflower rice or zucchini noodles. Sprinkle extra green onions and sesame seeds on top for a polished look.

If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. To reheat, warm in a skillet over medium heat, adding a splash of water or soy sauce to loosen the sauce. You can also freeze the cooked beef for up to 2 months. Thaw overnight in the fridge before reheating.

Pro tip: The flavors deepen and meld together even more after a day in the fridge, making leftovers just as delicious!
