Freezer: You can freeze the stir fry in a sealed container for up to 2 months. To reheat, thaw overnight in the fridge and use a pan over low heat.
Reheating: For best results, reheat in a skillet rather than the microwave. This helps to retain the texture of the beef and the caramelized onions.

Expert Tips for Chinese Beef and Onion Stir Fry
• Slice Against the Grain: Always slice the beef against the grain to ensure maximum tenderness. This simple step can make a world of difference.
• Preheat Properly: Heat your pan and oil sufficiently before adding ingredients. This prevents sticking and achieves a beautiful sear on your beef.
• Avoid Overcrowding: Cook the beef in smaller batches to maintain high heat and proper searing; overcrowding leads to steaming instead of browning.
• Customize Flavor: Don’t hesitate to enhance the dish with chili flakes or freshly grated ginger for an extra kick. Personalizing your Chinese Beef and Onion Stir Fry can cater to your taste!
• Thicken Wisely: When preparing the cornstarch slurry, ensure it’s mixed well to avoid lumps. Gradually adding it to the sauce as it simmers will yield the best result.
• Storage Tips: If you have leftovers, store them in an airtight container in the fridge. Reheat gently to keep the beef tender and flavorful.

Chinese Beef and Onion Stir Fry Recipe FAQs
How do I select the best beef for this stir fry?
Absolutely! When picking beef, flank steak is an excellent choice due to its tenderness and ability to absorb flavors. Look for cuts that are bright red with minimal dark spots. If you can’t find flank steak, sirloin or tenderloin also works great, offering a richer flavor but at a slightly higher price point.
What’s the best way to store leftovers?
Very! Store your leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, I recommend using a skillet over low heat. This way, you’ll maintain that delicious tenderness of the beef and the caramelized texture of the onions.
Can I freeze the Chinese Beef and Onion Stir Fry?
Absolutely! If you want to save some for later, you can freeze it in a sealed container for up to 2 months. To reheat, let it thaw overnight in the fridge. When you’re ready, warm it gently in a pan over low heat for the best results!
What should I do if my sauce is too thin?
Very! If your sauce isn’t thickening as you’d like, prepare an additional cornstarch slurry by mixing 1 tablespoon of cornstarch with 2 tablespoons of water. Return the stir fry to medium heat, pour in the slurry, and stir continuously until it thickens – this usually takes about 1-2 minutes.
Is this recipe safe for my pets or allergies?
I often make adjustments for allergies! This stir fry contains soy sauce, which can be high in sodium, so it’s best to avoid sharing it with pets. If you or anyone you’re cooking for has gluten allergies, use gluten-free soy sauce like tamari or coconut aminos as substitutes for a safer option.
How can I add more vegetables to my stir fry?
Very! Feel free to toss in your favorite veggies like bell peppers, snap peas, or broccoli for added color and nutrients. Simply add them during the stir-frying process after the onions, cooking until just tender, which usually takes about 2-3 minutes. The more the merrier with veggies!
