Ingredients

• 4 pounds beef roast (ribeye or sirloin)
• 2 tablespoons olive oil
• 1 teaspoon kosher salt
• 1 teaspoon black pepper
• 1 tablespoon fresh thyme leaves
• 4 cloves garlic cloves, minced
• 2 tablespoons butter, unsalted
• 1 tablespoon all-purpose flour
• 2 cups beef stock
• 3 tablespoons Dijon mustard
• 2 tablespoons capers, drained
• 1 tablespoon lemon juice

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Pat the beef roast dry with paper towels. Rub with olive oil, then season evenly on all sides with kosher salt, black pepper, and fresh thyme leaves.

Step 3

Heat a large oven-safe skillet or roasting pan over medium-high heat. Add 1 tablespoon of olive oil and sear the beef roast on all sides until browned, about 2-3 minutes per side.

Step 4

Transfer the skillet or roasting pan to the preheated oven. Roast for 60-90 minutes or until the internal temperature reaches 135°F (57°C) for medium-rare, or your desired level of doneness.

Step 5

While the beef is roasting, prepare the Dijon caper sauce. In a medium saucepan, melt the butter over medium heat.

Step 6

Add the minced garlic and cook until fragrant, about 1 minute. Stir in the flour and cook for 1 minute, stirring constantly to create a roux.

Step 7

Slowly whisk in the beef stock, ensuring there are no lumps. Bring the mixture to a simmer while stirring occasionally.

Step 8

Add the Dijon mustard, capers, and lemon juice. Simmer for 5-7 minutes, or until the sauce thickens slightly. Taste and adjust seasoning as needed.

Step 9

Once the roast beef is done, remove it from the oven and let it rest for 15 minutes before slicing.

Step 10

Slice the beef thinly and serve topped with the warm Dijon caper sauce. Enjoy!
