This recipe combines simple techniques with high-quality ingredients to create a restaurant-worthy dish in the comfort of your own kitchen. Whether you’re celebrating a special occasion or simply craving an extraordinary meal, this pan-roasted ribeye is sure to impress.

## The Allure of the Ribeye

The ribeye, also known as a Scotch fillet or Spencer steak depending on the region, is prized for its generous marbling – the streaks of fat that run throughout the muscle. This marbling renders during cooking, basting the steak from the inside out and resulting in a juicy, flavorful, and incredibly tender cut. The ribeye’s rich flavor profile makes it ideal for simple preparations that allow its natural qualities to shine.

## Ingredients: The Key to Success

* **Ribeye Steak:** Choose a high-quality ribeye steak, at least 1.5 inches thick, with ample marbling. Dry-aged ribeyes are even more flavorful, but any well-marbled ribeye will work beautifully. Aim for about 12-16 ounces per person.
* **Onions:** Yellow or sweet onions are best for caramelizing. Their natural sugars develop a deep, rich sweetness as they cook down.
* **White Truffle Butter:** This is the star of the show. You can purchase pre-made white truffle butter or make your own by combining softened unsalted butter with white truffle oil, grated Parmesan cheese, and a pinch of salt. A little goes a long way!
* **Olive Oil:** Use a good quality extra virgin olive oil for searing and caramelizing.
* **Butter:** Unsalted butter adds richness and helps to develop the beautiful crust on the steak and to caramelize the onions.
* **Fresh Thyme:** Optional, but adds a subtle earthy note to the caramelized onions.
* **Garlic:** Fresh garlic cloves, minced, infuse the onions with aromatic flavor.
* **Salt and Freshly Ground Black Pepper:** Essential for seasoning the steak and onions.
* **Optional Garnishes:** Fresh parsley, chives, or a sprinkle of sea salt can add a final touch of elegance.

## Detailed Recipe: Pan-Roasted Ribeye with Caramelized Onions and White Truffle Butter

**Yields:** 2 servings
**Prep time:** 20 minutes
**Cook time:** 30-40 minutes

### Equipment

* Heavy-bottomed skillet (cast iron is ideal)
* Small saucepan
* Tongs
* Meat thermometer

### Instructions

#### 1. Prepare the Ribeye:

* **Bring to Room Temperature:** Remove the ribeye steak from the refrigerator at least 30 minutes, and preferably an hour, before cooking. This allows the steak to cook more evenly. Pat the steak dry with paper towels. Removing excess moisture helps to achieve a better sear.
* **Season Generously:** Generously season the ribeye steak on both sides with salt and freshly ground black pepper. Don’t be shy! The seasoning will create a flavorful crust.

#### 2. Caramelize the Onions:

* **Slice the Onions:** Peel and thinly slice the onions into half-moons. Consistent thickness is key for even caramelization.
* **Sauté the Onions:** Heat 2 tablespoons of olive oil and 1 tablespoon of butter in a small saucepan over medium-low heat. Add the sliced onions and a pinch of salt. Salt helps to draw out the moisture from the onions, initiating the caramelization process.
* **Cook Low and Slow:** Cook the onions, stirring occasionally, for 30-40 minutes, or until they are a deep golden brown color and very soft. The key to perfect caramelized onions is patience. Don’t rush the process! Adjust the heat as needed to prevent burning.
* **Add Garlic and Thyme:** In the last 5 minutes of cooking, add the minced garlic and fresh thyme sprigs (if using) to the onions. Stir well and cook until the garlic is fragrant.
* **Set Aside:** Remove the caramelized onions from the saucepan and set aside in a bowl. Keep warm.

#### 3. Sear and Pan-Roast the Ribeye:

* **Heat the Skillet:** Place a heavy-bottomed skillet (cast iron is preferred) over high heat. Allow the skillet to heat up until it is smoking hot. This is crucial for achieving a good sear.
* **Add Oil:** Add 1 tablespoon of olive oil to the hot skillet. The oil should shimmer and almost smoke.
* **Sear the Steak:** Carefully place the seasoned ribeye steak in the hot skillet. Sear the steak for 2-3 minutes per side, or until a deep brown crust forms. Avoid moving the steak around during searing, as this can inhibit the formation of the crust.
* **Add Butter and Aromatics:** Reduce the heat to medium. Add 2 tablespoons of butter, 2 cloves of crushed garlic (optional), and a few sprigs of fresh thyme (optional) to the skillet. As the butter melts, tilt the skillet and use a spoon to baste the steak with the melted butter. This basting process adds flavor and helps to cook the steak evenly.
* **Cook to Desired Doneness:** Continue cooking the steak, basting frequently with the melted butter, until it reaches your desired level of doneness. Use a meat thermometer to check the internal temperature. Here are the recommended internal temperatures for different levels of doneness:
* **Rare:** 125-130°F (52-54°C)
* **Medium-Rare:** 130-135°F (54-57°C)
* **Medium:** 135-145°F (57-63°C)
* **Medium-Well:** 145-155°F (63-68°C)
* **Well-Done:** 155°F+ (68°C+)

*Note: Remove the steak from the skillet about 5-10 degrees below your desired final temperature, as it will continue to cook during resting (carryover cooking).*

#### 4. Rest and Slice:

* **Rest the Steak:** Remove the cooked ribeye steak from the skillet and place it on a cutting board. Tent it loosely with foil and let it rest for at least 10 minutes. Resting allows the juices to redistribute throughout the steak, resulting in a more tender and flavorful final product. Do not skip this step!
* **Slice Against the Grain:** After resting, slice the ribeye steak against the grain into 1/4-inch thick slices. Slicing against the grain shortens the muscle fibers, making the steak easier to chew.

#### 5. Assemble and Serve:

* **Plate the Steak:** Arrange the sliced ribeye steak on a serving platter or individual plates.
* **Top with Caramelized Onions:** Spoon the caramelized onions over the sliced steak.
* **Add White Truffle Butter:** Place a generous pat of white truffle butter on top of the caramelized onions. The butter will melt slightly from the heat of the steak, creating a rich and flavorful sauce.
* **Garnish and Serve:** Garnish with fresh parsley or chives, if desired. Serve immediately and enjoy!

## Tips for Success

* **Use a High-Quality Steak:** The quality of the ribeye steak is crucial to the success of this dish. Choose a steak with ample marbling for the best flavor and tenderness.
* **Don’t Overcrowd the Pan:** If cooking multiple steaks, cook them in batches to avoid overcrowding the pan. Overcrowding lowers the temperature of the pan and prevents the steak from searing properly.
* **Use a Meat Thermometer:** A meat thermometer is the best way to ensure that your steak is cooked to your desired level of doneness. Insert the thermometer into the thickest part of the steak, avoiding any bones.
* **Adjust Seasoning:** Taste the caramelized onions and steak after cooking and adjust the seasoning as needed. You may need to add more salt or pepper to taste.
* **Make Ahead:** The caramelized onions can be made ahead of time and stored in the refrigerator for up to 3 days. Simply reheat them gently before serving.
* **White Truffle Butter Alternatives:** If you can’t find white truffle butter, you can substitute with regular unsalted butter and a drizzle of white truffle oil. Alternatively, you can use garlic herb butter or compound butter of your choice.

## Variations

* **Balsamic Glaze:** Drizzle a balsamic glaze over the steak and caramelized onions for a touch of sweetness and acidity.
* **Blue Cheese:** Crumble blue cheese over the steak and onions for a tangy and savory flavor combination.
* **Mushroom Sauce:** Serve the steak with a creamy mushroom sauce for a more decadent experience.
* **Roasted Vegetables:** Serve the steak with roasted vegetables, such as asparagus, Brussels sprouts, or potatoes, for a complete meal.
* **Red Wine Reduction:** Create a red wine reduction sauce to drizzle over the steak for added depth of flavor.
