Ingredients

• 4 pieces Beef filet (center cut, approximately 1.5 inches thick)
• 2 tablespoons Coarse black peppercorns
• 2 teaspoons Coarse kosher salt
• 2 tablespoons Dijon mustard
• 3 tablespoons Olive oil
• 2 tablespoons Unsalted butter
• 2 cloves Garlic (smashed and peeled)
• 2 sprigs Fresh rosemary sprigs
• 1 cup Mayonnaise
• 2 tablespoons Prepared horseradish
• 1 tablespoon Fresh lemon juice
• 0.25 teaspoons Salt (for horseradish mayo)
• 0.25 teaspoons Freshly ground black pepper (for horseradish mayo)

Directions

Step 1

Remove the beef filets from the refrigerator and allow them to come to room temperature (about 30 minutes) before cooking.

Step 2

Crush the peppercorns coarsely using a mortar and pestle or by placing them in a resealable bag and using a rolling pin. Mix them with the kosher salt.

Step 3

Pat the beef filets dry with paper towels and coat each side with Dijon mustard. Press the peppercorn and salt mixture onto the surfaces, forming a crust.

Step 4

In a large, heavy skillet or cast-iron pan, heat the olive oil over medium-high heat until shimmering but not smoking.

Step 5

Place the filets in the skillet and sear for 2-3 minutes per side to create a golden-brown crust.

Step 6

Reduce the heat to medium, add the butter, garlic, and rosemary sprigs to the skillet, and use a spoon to baste the filets with the melted butter as they cook.

Step 7

Continue cooking the filets to your desired doneness: approximately 4-5 minutes for medium-rare or longer for more well-done. Use a meat thermometer to check for accuracy (125°F for medium-rare).

Step 8

Remove the filets from the skillet and let them rest on a plate for 5-7 minutes before serving.

Step 9

While the filets rest, prepare the horseradish mayonnaise. In a small bowl, whisk together mayonnaise, prepared horseradish, lemon juice, salt, and freshly ground black pepper until smooth and well combined.

Step 10

Serve the peppercorn and mustard beef filets hot with a dollop of horseradish mayonnaise on the side or drizzled over the top. Pair with roasted vegetables or mashed potatoes for a complete meal.
