Instructions:

1. Prep the Steak:

Begin by seasoning the ribeye steaks generously with salt and pepper on both sides. The ribeye steak is naturally flavorful due to its marbling, so you don’t need much seasoning—just enough to enhance its natural taste.

2. Cook the French Onions:

In a large skillet, heat 1 tablespoon of butter and 1 tablespoon of olive oil over medium heat. Add the sliced onions and sauté them slowly, stirring occasionally, for about 20-25 minutes. The goal is to caramelize the onions, which will bring out their natural sweetness and develop a deep golden-brown color.

If the onions start to stick to the pan, you can add a splash of water or beef broth to loosen them up. Once the onions are soft and golden, season with salt and pepper to taste. For extra depth of flavor, you can also add a splash of balsamic vinegar and cook for another minute to let the vinegar reduce and create a rich, tangy glaze.

3. Cook the Mushrooms:

In the same skillet (or another large skillet, if preferred), heat another tablespoon of butter and 1 tablespoon of olive oil over medium heat. Add the sliced mushrooms and sauté them for about 5-7 minutes, or until they become golden brown and release their moisture. Stir occasionally to ensure even cooking.

Add the fresh thyme, salt, and pepper, then cook for another minute to allow the flavors to meld together. If you want to add a little more richness, deglaze the pan with a splash of beef broth or red wine, scraping up any flavorful brown bits from the bottom of the pan. This will enhance the depth of flavor in the mushrooms.

4. Cook the Ribeye Steak:

While the onions and mushrooms are cooking, heat a cast-iron skillet or heavy-bottomed pan over high heat. Add 2 tablespoons of olive oil and allow it to get very hot (but not smoking). Once the pan is hot, place the ribeye steaks in the skillet. You should hear a sizzle when the steak hits the pan—this is the sound of the steak getting that beautiful sear.

Sear the steak for about 4-5 minutes on the first side, without moving it, to develop a nice brown crust. Flip the steak over and sear the other side for 3-4 minutes for medium-rare, or longer if you prefer your steak more done. Use a meat thermometer to check the internal temperature (130°F for medium-rare, 140°F for medium).

Once the steak reaches your desired doneness, add 1 tablespoon of butter to the pan and let it melt, spooning the butter over the steak for extra flavor. Remove the steak from the pan and let it rest for 5-10 minutes before serving.

5. Assemble the Dish:

To serve, place each ribeye steak on a plate. Spoon a generous amount of the caramelized French onions and sautéed mushrooms over the steak, ensuring each bite is full of savory, flavorful toppings.

Garnish with fresh parsley and a sprinkle of additional thyme if desired. Serve with your favorite side dishes, such as mashed potatoes, roasted vegetables, or a simple green salad, for a complete meal.

Tips for the Best Ribeye Steak with French Onions & Mushrooms:

1. Choose a Good Quality Ribeye: The ribeye is a naturally marbled cut, which makes it incredibly tender and flavorful. Look for a steak with good marbling, as the fat will render down during cooking, keeping the steak juicy and delicious.
2. Don’t Skip the Resting Step: After cooking the steak, let it rest for 5-10 minutes before cutting into it. This helps the juices redistribute, ensuring a juicy, tender steak when you take that first bite.
3. Caramelize the Onions Slowly: Be patient when cooking the onions. Low and slow is the way to go for perfectly caramelized onions. This process can take 20-25 minutes, but the results are totally worth it.
4. Use a Cast-Iron Skillet: A cast-iron skillet is perfect for cooking steak because it retains heat well, ensuring a nice, even sear. If you don’t have one, any heavy-bottomed pan will work, but cast iron is ideal.
5. Customize the Toppings: If you want to add more depth to the mushrooms, you can throw in a little garlic, shallots, or even a splash of cream for a richer sauce. Likewise, feel free to add a sprinkle of blue cheese or grated parmesan over the mushrooms and onions for an extra layer of flavor.
6. Pair with the Right Side Dishes: Since the steak and toppings are rich and savory, consider serving them with a simple side like roasted vegetables, a fresh green salad, or creamy mashed potatoes to balance the meal.
