Stepwise Method: Quick Skillet Steak with Onions and Mushrooms

Step 1: Prepare the Ingredients
Start by slicing your onion into rings and the mushrooms into even pieces. This ensures they cook at the same rate. If you haven’t done so already, slice the beef into thin strips to ensure quick cooking.
Step 2: Heat the Skillet
Place your skillet over medium-high heat and add a light spray of olive oil. Allow the skillet to heat up for a minute or two until it’s hot but not smoking.
Step 3: Cook the Onions
Add the sliced onions to the skillet and sauté them for about 3-4 minutes, or until they start to become translucent. Stir occasionally to avoid burning.
Step 4: Add the Mushrooms
Once the onions are soft, add the sliced mushrooms to the skillet. Continue to cook for another 5 minutes, stirring occasionally, until the mushrooms are tender and have released their moisture.
Step 5: Season and Add the Steak
Sprinkle the garlic powder, kosher salt, and fresh cracked pepper over the onion and mushroom mixture. Next, add the sliced beef to the skillet, ensuring it is spread out evenly.
Step 6: Cook the Steak
Cook the steak for about 3-5 minutes, depending on your desired level of doneness. Stir occasionally to ensure even cooking. The steak should be browned and cooked through but still tender.
Step 7: Serve and Enjoy
Once everything is cooked to perfection, remove the skillet from the heat. Serve the Quick Skillet Steak with Onions and Mushrooms hot, perhaps with a side of rice or a fresh salad. Enjoy every bite!

Troubleshooting Tips
- If the steak is tough, it may need to be cooked for a shorter amount of time or sliced more thinly.
- Ensure the skillet is hot enough before adding the steak to achieve a good sear.
- Add a splash of beef broth or water if the mixture seems too dry while cooking.
