How to Make Slow Cooker Cashew Beef and Broccoli Stir-Fry (Step-by-Step)
This recipe is simple and allows for an aromatic, hearty meal with minimal fuss.
Step 1: Prep the Beef
Start by slicing your flank steak, ensuring you're cutting against the grain. This little trick helps keep the meat tender and delightful to chew on. The aroma of freshly sliced beef always makes my mouth water with anticipation!
Step 2: Mix the Sauce
In a bowl, whisk together the soy sauce, oyster sauce, brown sugar, cornstarch, and beef broth. Make sure you blend this until it's smooth and glossy-this mixture becomes the lifeblood of your dish.
Step 3: Layering the Ingredients
In your slow cooker, combine the sliced flank steak, minced garlic, minced ginger, and the broccoli florets. Pour your prepared sauce over the top, and then give it a gentle toss. This ensures that each piece of meat and broccoli is kissed by the savory goodness.
Step 4: Cook Low and Slow
Cover your slow cooker and cook on low for 4 to 6 hours. The magic really happens during this time-the beef becomes beautifully tender, and the house fills with mouthwatering scents. Just keep an ear out for that cozy bubbling sound; it's truly a homey symphony.
Step 5: Finish with Cashews
In the last 30 minutes of cooking, stir in the cashews. These little gems add a delightful crunch that balances the tenderness of the beef and broccoli-a real joy for your texture-loving palate.
Step 6: Serve it Up
Once finished, drizzle a touch of sesame oil for an added layer of flavor before serving over a bed of fluffy rice. The glossy sauce coats every piece delectably, making the dish not only delicious but visually appealing.

Common Mistakes to Avoid
- Skipping the slicing properly: Always slice against the grain to keep the beef tender; otherwise, you'll end up with chewy bites.
- Overcooking the broccoli: If you add the broccoli too early, it can become mushy. Throw it in during the last hour to retain that vibrant color and crispness.
- Neglecting to whisk the sauce thoroughly: Ensure the cornstarch is fully combined with the other ingredients to avoid clumps in your final dish.
Tips and Tricks for Success
- Use high-quality soy sauce: The authenticity of your dish is greatly influenced by the soy sauce you choose. Opt for a brand you love.
- Experiment with veggies: While broccoli is traditional, feel free to mix in bell peppers or snap peas for a bit of extra color and nutrition.
- Adjust the sweetness: Depending on your taste, feel free to add more or less brown sugar. A little sweetness can help balance savory flavors.
Variations
- Substitute flank steak with chicken or tofu for different protein options.
- Replace cashews with peanuts for a different nutty flavor.
- Add a splash of lime juice for a citrusy twist.
- Incorporate additional vegetables such as carrots or snow peas.
How to Serve
- Serve over a bed of fluffy rice or quinoa.
- Garnish with sliced green onions or sesame seeds for extra flair.
- Pair with a side of steamed vegetables for a well-rounded meal.

Make Ahead and Storage
- Make Ahead: Prepare the sauce in advance and store it in the refrigerator for up to 2 days.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
- Reheating: Gently warm them on the stove over low heat, adding a splash of broth if the sauce has thickened too much.
- Freezing: This dish can be frozen, but it's best to freeze the beef and sauce separately from the broccoli for optimal texture. Freeze for up to 3 months.
