Preparation Phase & Tools to Use
To get started with making the Beef, Onion & Mushroom Stir-Fry, you’ll want to ensure your kitchen and workspace are well-prepared. Begin by gathering all your ingredients and measuring them out to save time during the cooking process. It’s a good idea to have your vegetables prepped ahead of time—slicing the onions and mushrooms can expedite the cooking phase significantly.
For this dish, you will need a large skillet or wok to properly sear the beef and vegetables. Using a non-stick skillet will help prevent sticking and make cleanup easier. You’ll also want to have a spatula or wooden spoon on hand for stirring the mixture as it cooks. Having everything ready to go before you start will ensure that you can create this fast, savory dinner seamlessly.

Ingredients
- 7 ounces beef steak, thinly sliced
- 8 ounces mushrooms, sliced
- 2 large brown onions, cut into wedges
- 1 tablespoon plus 1 teaspoon cooking oil
- 1 tablespoon plus 1 teaspoon oyster sauce
- 1 tablespoon soy sauce
- 2 teaspoons ketchup
- 2 tablespoons beef broth or water
- 1 teaspoon cornstarch
- 1/2 tablespoon cold water
- Salt and black pepper, to taste
- Cooked white rice, for serving
- 2 green onions, sliced, for garnish
Instructions
Step 1: Marinate the Beef
Start by tenderizing the beef and enhancing its flavor. In a mixing bowl, combine the thinly sliced beef with oyster sauce, a teaspoon of oil, cornstarch, and cold water. This marinade not only infuses the meat with delicious flavor but also helps to keep it juicy as it cooks. Allow the beef to marinate for at least 10 minutes while you prepare the other ingredients.
Step 2: Mix the Sauces
In a separate small bowl, whisk together the soy sauce, ketchup, and beef broth or water. This savory mixture will serve as the sauce for your stir-fry, bringing everything together with a delightful umami flavor. Set this aside while you cook the vegetables.
Step 3: Cook the Onions
Heat a tablespoon of oil in your skillet over medium heat. Once heated, add the wedged onions. Sauté them for about 5 minutes or until they become soft and slightly caramelized. Stir occasionally to ensure even cooking and prevent burning. The natural sweetness from the onions will start to develop, creating a wonderful base for the stir-fry.
Step 4: Add the Mushrooms
Next, it’s time to add in the sliced mushrooms. Continue cooking for an additional 3 to 4 minutes until the mushrooms are tender and have released their moisture. The mushrooms will soak up the flavors from the onions, creating an irresistible layer of taste.
Step 5: Sear the Beef
Push the cooked vegetables to one side of the skillet and add the marinated beef to the empty side. Sear the beef for about 2-3 minutes, stirring gently until it’s browned on the outside. It’s important not to overcrowd the pan at this step, as it may result in steaming instead of searing. Once the beef is nearly cooked through, combine it with the vegetables.
Step 6: Combine and Thicken the Sauce
Pour in the sauce mixture you prepared earlier into the skillet with the beef and vegetables. Stir everything together and allow it to cook for an additional 2-3 minutes or until the sauce thickens slightly. This is where all the flavors meld together, creating a deliciously decadent stir-fry.
Step 7: Serve and Enjoy
Finally, season the stir-fry with salt and black pepper to taste. Serve it hot, spooned over cooked white rice and garnished with sliced green onions for a pop of color and crunch. Enjoy your Beef, Onion & Mushroom Stir-Fry as a satisfying and filling meal!

Cooking Notes
- Ensure your beef is thinly sliced against the grain for maximum tenderness.
