Beef And Mushroom Stir-Fry Cooking Guide

Now that you have everything ready, let’s dive into the step-by-step cooking process that will have your taste buds dancing!
Step 1: Prepare the Meat
Start by placing the diced beef tenderloin or flank steak in a bowl. Add the baking soda and 1 tablespoon of cornstarch, tossing to coat the beef evenly. This step is crucial for achieving tender, juicy meat.
Step 2: Marinate
Add 1 tablespoon of soy sauce and 1 tablespoon of reduced-sodium soy sauce to the beef. Mix well and let it marinate for about 15 minutes while you prep the other ingredients.
Step 3: Sauté the Aromatics
Heat 1 tablespoon of olive oil in your wok or skillet over high heat. Add the sliced garlic and sauté for about 30 seconds until fragrant, being careful not to burn it.
Step 4: Cook the Beef
Increase the heat to high and add the marinated beef to the skillet. Stir-fry for about 3-4 minutes until the beef is browned and cooked through. Remove the beef from the skillet and set aside.
Step 5: Stir-Fry the Mushrooms
In the same skillet, add the remaining tablespoon of olive oil. Toss in the quartered baby bella mushrooms and stir-fry for about 4-5 minutes until they are tender and golden brown.
Step 6: Make the Sauce
In a small bowl, whisk together the oyster sauce, dark soy sauce, sugar, and 4 tablespoons of water. In another bowl, mix the remaining 1/2 tablespoon of cornstarch with a splash of water to create a slurry.
Step 7: Combine Ingredients
Return the cooked beef to the skillet with the mushrooms. Pour the sauce mixture over the beef and mushrooms, stirring to combine. Then add the cornstarch slurry and mix well, cooking for another 1-2 minutes until the sauce thickens and coats the beef and mushrooms beautifully.
Step 8: Serve
Remove from heat and serve your Beef And Mushroom Stir-Fry immediately over steamed rice or noodles. Enjoy this deliciously quick meal with a sprinkle of sesame seeds or sliced green onions if desired!
Dietary Swaps & Alternatives

If you’re looking to modify this recipe for dietary preferences or restrictions, consider the following swaps:
- Beef alternatives: Substitute the beef with chicken, tofu, or tempeh for a different protein source.
- Gluten-free option: Use tamari instead of soy sauce for a gluten-free version of this dish.
- Vegetable varieties: Add bell peppers, broccoli, or snap peas to increase the vegetable content.
- Low-sodium option: Opt for low-sodium soy sauce and oyster sauce to reduce salt intake.
Learn from These Mistakes
Avoid common pitfalls to ensure your Beef And Mushroom Stir-Fry turns out perfect every time:
- Overcrowding the pan: If you add too much beef at once, it will steam instead of sear. Cook in batches if necessary.
- Not slicing the beef properly: Ensure your beef is sliced against the grain for maximum tenderness.
- Using cold meat: Allow the meat to sit at room temperature for a few minutes before cooking for even cooking.
- Skipping the marinade: Don’t skip the marinating step, as it enhances flavor and tenderness.
Store, Freeze & Reheat
To keep your Beef And Mushroom Stir-Fry fresh, follow these storage tips:
- Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 3 days.
- Freezing: Freeze in portions for up to 2 months. Thaw overnight in the fridge before reheating.
- Reheating: Reheat in a skillet over medium heat or in the microwave until heated through. Add a splash of water if needed to loosen the sauce.
