The cooking process explained
You might think slow cooking is a lengthy process, but that’s the beauty of it! With just a handful of straightforward steps, this recipe comes together effortlessly. The slow cooker does the heavy lifting while you raise a glass of wine, catch up on your favorite show, or tackle that pile of laundry.
Imagine this: you’ll start by combining your flank steak, soy sauce, brown sugar, and warming spices into the slow cooker, let it work its magic for several hours, and add the broccoli just before serving. Simple, right?
What you’ll need
To create this delightful dish, gather the following ingredients:
- 1 pound flank steak, sliced thinly
- 2 cups broccoli florets
- 1/4 cup soy sauce
- 1/4 cup brown sugar
- 2 cloves garlic, minced
- 1 teaspoon ginger, minced
- 1 tablespoon cornstarch
- 1 tablespoon vegetable oil
- Salt and pepper to taste
- Cooked rice for serving
Feel free to use different veggies or even swap out the flank steak for chicken or tofu if you’re looking to mix things up!
Directions to follow
- In your slow cooker, combine the sliced flank steak, soy sauce, brown sugar, minced garlic, minced ginger, and vegetable oil. Stir everything together until well incorporated.
- Cover and cook on low for 4-6 hours, or until the beef is meltingly tender.
- About 30 minutes before you’re ready to eat, toss in the broccoli florets and sprinkle the cornstarch evenly over the top. Stir gently to mix it in. This helps thicken the sauce beautifully.
- Season with salt and pepper to taste before serving.
- Dish up the beef and broccoli over warm, fluffy rice.

Best ways to enjoy it
When it comes to serving Slow Cooker Mongolian Beef and Broccoli, I recommend a generous scoop over a bed of rice. The rice absorbs all the delicious sauce, and you really want to soak up every bit of that flavor! You might also consider pairing it with a light cucumber salad for a refreshing crunch or some steamed dumplings on the side for that authentic Asian flair.
Storage and reheating tips
If you find yourself with leftovers (which can be a delightful treat), storing them properly is key. Let the dish cool completely before transferring it to an airtight container. It’ll keep well in the fridge for about 3-4 days. For longer storage, you can freeze it – just be mindful to freeze it before adding the broccoli as it may not reheat well. When ready to eat, thaw overnight in the fridge and reheat gently on the stove, adding a splash of water if needed to loosen up the sauce.
Helpful cooking tips
- When slicing the flank steak, try to cut against the grain to ensure tenderness.
- If you prefer your broccoli on the softer side, feel free to toss it in a bit earlier, though I love that crisp bite.
- Serving the dish with a sprinkle of sesame seeds or sliced green onions can elevate the presentation beautifully.
Creative twists
Feeling adventurous? Here are some ideas to switch things up:
- Spicy Kick: Add a dash of red pepper flakes or sriracha for some heat.
- Veggie Boost: Toss in bell peppers, snap peas, or even mushrooms for added texture and flavor.
- Coconut twist: Use coconut aminos instead of soy sauce for a slightly sweeter, gluten-free option.
Common questions
How long does it take to prepare?
Prep time is minimal – about 15 minutes to slice and mix everything into the slow cooker, then the magic happens over the next few hours!

Swap out the soy sauce for a gluten-free soy sauce or tamari, and you’re good to go!
