Full Recipe

Ingredients

For the Beef Stir-Fry:

• 500g beef, sliced thinly

• ½ teaspoon baking soda (for tenderizing)

• 1 tablespoon flour

• 1 tablespoon rice vinegar

• 2 tablespoons soy sauce

• ½ red bell pepper, sliced

• ½ green bell pepper, sliced

• 2 cloves garlic, minced

• 1 chili pepper, finely chopped

• 1 onion, sliced

• 200ml broth (beef or vegetable)

• 1 teaspoon cornstarch (for thickening)

• 1 tablespoon soy sauce

Cooking Directions

1. Prepare the Beef:
   Begin by placing your thinly sliced beef into a bowl. Add baking soda, rice vinegar, flour, and 2 tablespoons of soy sauce. Mix well until every piece of beef is coated. Let it marinate for about 10–15 minutes. This step ensures your beef becomes incredibly tender and flavorful once cooked.

2. Sear the Beef:
   Heat a wok or large skillet over medium-high heat. Add a splash of oil, then add the marinated beef in batches. Don’t overcrowd the pan — you want the meat to sear, not steam. Cook each batch for about 1–2 minutes per side until browned, then remove from the pan and set aside.

3. Sauté the Aromatics:
   In the same pan, add a bit more oil if needed. Toss in the minced garlic, sliced onion, and chopped chili pepper. Stir-fry for about 1 minute until fragrant — this forms the base of your sauce’s aroma.

4. Add the Vegetables:
   Add the red and green bell peppers. Stir-fry for another 2–3 minutes, just until they start to soften but still retain a bit of crunch. The vibrant colors and fresh texture will make the dish pop.

5. Combine Everything:
   Return the beef to the pan. Mix everything well so that the flavors meld together. Pour in the broth and stir to combine.

6. Thicken the Sauce:
   In a small bowl, mix the cornstarch with a tablespoon of water to create a slurry. Pour this into the pan while stirring continuously. Add the remaining tablespoon of soy sauce. Within a minute or two, the sauce will start to thicken and coat the beef and vegetables beautifully.

7. Final Adjustments:
   Taste and adjust seasoning as needed — you can add a pinch of salt, extra soy sauce, or even a dash of sugar to balance the flavors.

8. Serve:
   Serve your Beef Stir-Fry hot over steamed jasmine rice or noodles. Garnish with sesame seeds or chopped green onions if desired.

The Origins and Inspiration Behind the Dish

This recipe takes inspiration from traditional Asian stir-fry techniques, where speed and high heat lock in flavor and texture. Stir-frying originated in China but has become a global cooking method beloved for its efficiency and flavor. The combination of soy sauce, garlic, and chili is a nod to the Southeast Asian style of balancing salty, sweet, and spicy notes. This version blends those influences into a comforting dish that feels both familiar and exciting.

Ingredient Spotlight

• Beef: Thinly sliced sirloin, flank, or tenderloin works best. The baking soda tenderizes the meat, ensuring a melt-in-your-mouth texture.

• Bell Peppers: They bring color, crunch, and a natural sweetness that complements the savory beef.

• Garlic and Chili: These two create the flavor backbone of the dish. Garlic adds warmth, while chili introduces a subtle heat that wakes up the palate.

• Soy Sauce: The umami powerhouse that adds depth and a rich, savory profile.

• Cornstarch: This simple ingredient transforms the thin broth into a glossy sauce that clings to every bite.

Storage and Reheating Tips

Store leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, warm it in a skillet over medium heat with a splash of broth or water to loosen the sauce. Avoid microwaving for too long, as it can overcook the beef and make it chewy. If freezing, allow the stir-fry to cool completely before transferring it to a freezer-safe bag or container. Thaw in the fridge overnight before reheating.

Common Variations to Try

• Spicy Garlic Beef: Add extra chili or a spoonful of chili paste for a fiery version.

• Ginger-Soy Stir-Fry: Include a tablespoon of grated fresh ginger for extra zing.

• Vegetable Boost: Toss in snap peas, broccoli florets, or baby corn to make it more veggie-packed.

• Sweet-Sour Style: Add a tablespoon of brown sugar and a splash of rice vinegar for a tangy twist.

• Tofu Substitute: For a vegetarian option, replace beef with firm tofu and use vegetable broth.

Pairing Recommendations

This stir-fry is best served with steamed jasmine rice or egg noodles. For a lighter option, try it with cauliflower rice. Complement the meal with sides like Asian cucumber salad, stir-fried bok choy, or steamed dumplings. To drink, a cold glass of iced green tea or a crisp lager pairs perfectly with the bold, savory flavors.

Health Benefits
