Ingredients

• 6 pounds boneless baron of beef roast (top or bottom round roast)
• 3 tablespoons Dijon mustard
• 2 tablespoons olive oil
• 2 tablespoons fresh thyme leaves, chopped
• 2 teaspoons kosher salt
• 1 teaspoon black pepper, freshly ground
• 4 cloves garlic cloves, minced
• 1 large yellow onion, quartered
• 3 medium carrots, peeled and sliced into large chunks
• 2 stalks celery stalks, chopped into large pieces
• 1 cup dry red wine
• 3 cups beef stock
• 1 leaf bay leaf

Directions

Step 1

Preheat your oven to 325°F (160°C).

Step 2

In a small bowl, whisk together the Dijon mustard, olive oil, minced garlic, chopped thyme, kosher salt, and black pepper to create the seasoning paste.

Step 3

Pat the baron of beef roast dry with paper towels. Rub the seasoning paste evenly over the surface of the roast.

Step 4

Place the quartered onion, carrots, and celery stalks in the bottom of a large roasting pan to create a vegetable bed. Place the roast on top of the vegetables, fat side up.

Step 5

Pour the red wine and 2 cups of beef stock into the roasting pan to prevent the vegetables from burning and to create the base for the au jus.

Step 6

Add the bay leaf to the liquid in the pan.

Step 7

Roast the beef in the preheated oven for approximately 20-25 minutes per pound, or until an internal thermometer reads 125°F (52°C) for medium-rare or 135°F (57°C) for medium. Baste the roast with the pan drippings every 45 minutes.

Step 8

Once cooked to your desired doneness, transfer the roast to a cutting board and tent loosely with foil. Let it rest for 20 minutes before slicing.

Step 9

While the roast rests, strain the pan drippings and vegetables through a fine mesh sieve into a medium-sized saucepan. Discard the solids and skim off excess fat from the liquid.

Step 10

Add the remaining 1 cup of beef stock to the saucepan and bring the liquid to a gentle simmer over medium heat. Adjust seasoning with salt and pepper as needed.

Step 11

Slice the baron of beef thinly against the grain and serve with the warm au jus drizzled over the top or in small individual bowls for dipping.
