## Ingredients:

For the steak medallions:

• 1.5 lb beef tenderloin or sirloin, cut into 8 medallions (about 1.5 inches thick)
• 1.5 tsp coarse kosher salt (or 1 fine sea salt)
• 2.5 tsp freshly ground black pepper (coarse grind)
• 4 cloves garlic, finely minced
• 1 tsp garlic powder
• 2 tbsp olive oil
• 2 tbsp unsalted butter
• 1 tbsp fresh thyme leaves (or 1 tsp dried thyme)
• 1 tbsp fresh rosemary, finely chopped (or 1 tsp dried rosemary)
• 1/3 cup low-sodium beef broth
• 1/4 cup dry red wine or additional beef broth
• 2 tbsp cold unsalted butter (for finishing the pan sauce)
• Optional: a squeeze of fresh lemon juice or 1 tsp Worcestershire sauce for balance

For the buttery mashed potatoes:

• 2 lb russet or Yukon Gold potatoes, peeled and cut into 1.5-inch chunks
• 1.5 tsp kosher salt (for boiling water)
• 4 tbsp unsalted butter, room temperature, cut into pieces
• 1/2 to 3/4 cup warm whole milk or half-and-half (adjust for desired creaminess)
• 1/4 cup sour cream or heavy cream (optional but recommended for richness)
• 1/2 tsp garlic powder or 1 clove garlic, gently smashed and simmered in the milk (optional)
• 1/2 tsp freshly ground black pepper
• Additional salt to taste

For garnish:

• 2 tbsp fresh parsley, finely chopped
• Additional cracked black pepper
• Flaky sea salt (optional)

## Method:

### Step 1: Prepare the Steak Medallions

Pat the steak medallions dry with paper towels on all sides to ensure good browning. In a small bowl, mix the salt, coarse black pepper, and garlic powder. Season the medallions generously on all sides with this mixture, gently pressing it into the meat. Let the seasoned medallions rest at room temperature for about 20–30 minutes while you prepare the potatoes; this helps them cook more evenly.

### Step 2: Start the Mashed Potatoes

Place the peeled, chunked potatoes in a large pot and cover with cold water by about 1 inch. Add 1.5 tsp kosher salt to the water. Bring to a boil over medium-high heat, then reduce to a gentle boil and cook for 12–18 minutes, or until the potatoes are very tender when pierced with a fork and just starting to break apart. While the potatoes cook, warm the milk or half-and-half in a small saucepan over low heat. If using a garlic clove for flavor, add it to the milk while it warms, then remove the clove before adding the milk to the potatoes. Do not boil the milk; just keep it warm.

### Step 3: Sear the Steak Medallions

Heat a large heavy skillet (cast iron is ideal) over medium-high heat until very hot. Add the olive oil and 2 tbsp unsalted butter; swirl until the butter is melted and starting to foam. Place the medallions into the hot pan, leaving space between each piece. Do not overcrowd the pan; work in two batches if necessary. Sear without moving them for about 3–4 minutes on the first side, until a deep brown crust forms. Flip the medallions and add the minced garlic, thyme, and rosemary to the pan, scattering them around the meat (not directly on top so they do not burn). Sear the second side for about 3–4 minutes more for medium-rare, or to your preferred doneness. For accuracy, use an instant-read thermometer: 125°F (52°C) for rare, 135°F (57°C) for medium-rare, 145°F (63°C) for medium.

### Step 4: Baste and Rest the Steak

During the last minute of cooking, slightly tilt the pan and use a spoon to baste the tops of the medallions with the garlicky, herb-infused butter and juices. Transfer the cooked medallions to a warm plate, loosely tent with foil, and let them rest for 8–10 minutes to redistribute the juices.

### Step 5: Make the Garlic Pepper Pan Sauce

With the skillet still over medium heat, check the garlic and herbs; if any pieces look too dark or burnt, remove them with a spoon to keep the sauce from tasting bitter. Carefully pour in the red wine (or a splash of beef broth) to deglaze the pan, scraping up all the browned bits from the bottom with a wooden spoon. Add the beef broth and bring to a simmer. Let the sauce reduce by about half, 3–5 minutes, until slightly thickened and glossy. Reduce the heat to low and whisk in the 2 tbsp of cold unsalted butter, 1 piece at a time, until the sauce becomes silky and lightly thickened. If desired, add a small squeeze of lemon juice or 1 tsp Worcestershire sauce to brighten the flavors. Taste and adjust seasoning with a pinch of salt and a bit more black pepper if needed. Keep warm on very low heat.

### Step 6: Finish the Buttery Mashed Potatoes

When the potatoes are very tender, drain them well in a colander and let them sit for 2–3 minutes to release excess steam; this helps keep the mash fluffy. Return the potatoes to the warm pot. Mash with a potato masher or press through a potato ricer for extra smooth potatoes. Add the butter pieces and mash until they melt into the potatoes. Pour in about half of the warm milk (removing the garlic clove if used) and continue mashing or stirring until creamy. Add more warm milk as needed to reach your desired consistency. Stir in the sour cream or heavy cream (if using), then season with 1/2 tsp black pepper and additional salt to taste. Mix until smooth and fluffy but avoid overworking the potatoes, which can make them gummy. Keep warm over very low heat or with the lid on until ready to serve.

### Step 7: Plate the Dish

Spoon a generous portion of buttery mashed potatoes onto each plate, making a slight well in the center. Place 1–2 steak medallions beside or slightly on top of the potatoes. Spoon the garlic pepper pan sauce over the steak medallions and allow a little to pool over the potatoes. Garnish with chopped fresh parsley, a sprinkle of extra cracked black pepper, and a pinch of flaky sea salt if you like.

### Step 8: Serve

Serve immediately while hot, with any remaining sauce in a small pitcher or bowl on the table. Pair with a simple green vegetable such as sautéed green beans, roasted asparagus, or a crisp salad to balance the richness.

## Serving Suggestions & Pairings

This luscious dish pairs perfectly with a salad of mixed greens dressed with a light vinaigrette or a pile of sautéed green beans for a pop of color. Roasted asparagus or Brussels sprouts could also enhance the plate beautifully, adding texture and flavor dimensions. If you’re feeling indulgent, a glass of dry red wine, such as Cabernet Sauvignon or Merlot, complements the richness of the steak magnificently.

## Storage & Leftovers Guide

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm the steak and mashed potatoes in the microwave or in a skillet over low heat. If the mashed potatoes become stiff, just add a splash of milk or cream to loosen them up.

## Kitchen Wisdom & Success Tips

• Allow the steak medallions to rest after cooking; this locks in the juices, making each bite tender and succulent.
• Use room temperature ingredients for the mashed potatoes; this helps them blend better and results in a creamier texture.
• Don’t rush the searing step; achieving a nice crust is crucial for flavor depth.

## Flavor Variations & Adaptations

Feel free to adapt the herbs used in the steak medallions; fresh oregano or parsley can be delightful. For the mashed potatoes, consider adding roasted garlic for a deeper flavor, or even some shredded cheese for extra creaminess.

## Reader Questions & Solutions

1. Why is my steak tough?

   • Ensure you are using a good cut of beef, such as tenderloin or sirloin. Letting the steak rest after cooking is also essential to allow juices to redistribute.

2. How do I prevent my mashed potatoes from being gumy?

   • Avoid overworking the potatoes after mashing, as this can lead to a gluey texture. Also, draining the potatoes well helps maintain fluffiness.

3. What should I do if my pan sauce is too salty?

   • Balance the flavors by adding a splash of vinegar or a squeeze of lemon juice, or dilute the sauce with more beef broth.

4. Can I use yellow potatoes instead of russet?

   • Absolutely! Yukon Golds are creamy and flavorful, perfect for whipped potatoes.

5. How can I tell if my steak is done without a thermometer?

   • You can use the touch test: a rare steak feels soft and squishy, medium feels slightly firmer but still soft, and well-done feels very firm.
