TENDER BEEF & ONION Stir-Fry: Tenderizes Beef Deliciously & Boosts the Flavor!

Last modified date

Hello food lovers!

Today, I’m excited to share a classic Japanese home-style dish that’s both incredibly flavorful and surprisingly easy to make: Tender Beef & Onion Stir-fry. This dish, often reminiscent of “Yakiniku” (Japanese BBQ) flavors, features succulent beef, sweet onions, and crisp bell peppers, all coated in a savory and slightly sweet sauce. It’s perfect for a quick weeknight dinner and pairs wonderfully with a bowl of steamed rice.

Let’s get cooking!


Ingredients

Here’s what you’ll need:

For the Main Stir-fry:

  • Beef (thinly sliced, sirloin or ribeye recommended): 180g (approx. 6.3 oz)

  • Onion: 150g (approx. 5.3 oz, about 1 medium)

  • Green Bell Pepper (Piman): 60g (approx. 2.1 oz, about 1 medium)

  • Garlic: 1 clove

  • Cooking Oil: 2 tsp (1 tsp for beef, 1 tsp for onions/veggies)

For the Beef Marinade (to make it extra tender!):

  • Soy Sauce: 1 tsp

  • Sugar: 1/2 tsp

  • Potato Starch (Katakuriko) or Cornstarch: 2 tsp

  • Vegetable Oil (or Sesame Oil): 1 tsp

  • Baking Soda (Juso): 1/3 tsp (This is key for tenderizing!)

For the Yakiniku-style Sauce:

  • Soy Sauce: 2 tbsp

  • Sugar: 1.5 tbsp (1 tbsp + 1 ½ tsp)

  • Apple Juice: 2 tsp

  • Mirin (Sweet Rice Wine): 1 tsp

  • Sake (Japanese Rice Wine): 1 tsp

  • Rice Vinegar: 1/2 tsp

  • Grated Ginger: 1/3 tsp

  • White Pepper: A pinch

  • MSG (e.g., Ajinomoto): A pinch (optional, for an umami boost)

(Note: 1 US cup = approx. 240ml. Teaspoon (tsp) and Tablespoon (tbsp) measurements are generally consistent internationally for small quantities.)


Instructions (Step-by-Step)

Let’s bring this delicious stir-fry to life in just a few simple steps!

  1. Prepare Your Ingredients:

    • Thinly slice the beef against the grain.

    • Cut the onion into wedges.

    • Cut the green bell pepper into bite-sized pieces.

    • Mince the garlic.

  2. Marinate Beef & Mix Sauce:

    • In a bowl, combine the sliced beef with all the “Beef Marinade” ingredients (soy sauce, sugar, potato/cornstarch, oil, baking soda). Mix well with your hands to ensure each piece is coated. Set aside.

    • In a separate small bowl, combine all the “Yakiniku-style Sauce” ingredients (soy sauce, sugar, apple juice, mirin, sake, rice vinegar, grated ginger, white pepper, and MSG if using). Whisk until the sugar is dissolved.

  3. Cook the Beef:

    • Heat 1 teaspoon of cooking oil in a large skillet or wok over medium-high heat.

    • Add the marinated beef in a single layer (cook in batches if necessary to avoid overcrowding). Stir-fry until the beef is browned and just cooked through.

    • Remove the beef from the skillet and set it aside on a plate.

  4. Stir-fry Vegetables & Combine:

    • Wipe the skillet clean if needed, or use a fresh one. Add the remaining 1 teaspoon of cooking oil and heat over medium heat.

    • Add the minced garlic and onion wedges. Stir-fry until the onions start to soften and become translucent (about 2-3 minutes).

    • Add the green bell pepper pieces and stir-fry for another minute until slightly tender-crisp.

    • Return the cooked beef to the skillet. Pour the prepared Yakiniku-style sauce over everything.

    • Continue to stir-fry over medium heat, tossing constantly, until the sauce has thickened and coats all the ingredients, and much of the liquid has evaporated (about 2-3 minutes).

  5. Serve & Enjoy!

    • Transfer the Tender Beef & Onion Stir-fry to a serving dish. It’s best enjoyed immediately with hot steamed rice.


Tips for Success:

  • Don’t overcrowd the pan: Cook the beef in batches if necessary to ensure it sears properly rather than steams.

  • High heat for stir-frying: Generally, stir-frying requires medium-high to high heat for that characteristic “wok hei” (breath of the wok) flavor, but adjust as needed to prevent burning.

  • Prep everything first (Mise en place): Stir-frying goes quickly, so have all your ingredients chopped, measured, and ready to go before you start cooking.

I hope you enjoy this Tender Beef & Onion Stir-fry! It’s a favorite in my kitchen, and I’m sure it will be in yours too. Don’t forget to check out the video for a visual guide, and let me know in the comments if you try it!
