Ingredients You'll Need

For the beef:

  • 1 ½ to 2 pounds sirloin roast
  • 8–10 slices bacon
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • ½ teaspoon black pepper
  • ½ teaspoon dried thyme
  • Salt, to taste

For the cooking liquid:

  • 1 cup beef broth
  • 2 tablespoons Worcestershire sauce
  • 1 tablespoon Dijon mustard

You can adjust the seasonings to suit your taste, but the combination of garlic, onion, thyme, Worcestershire, and Dijon gives the beef a particularly savory finish.

How to Make Slow Cooker Bacon-Wrapped Sirloin

1. Prepare the Sirloin

Pat the roast dry with paper towels.

Combine the garlic powder, onion powder, black pepper, thyme, and salt in a small bowl. Rub the seasoning mixture over all sides of the beef.

Allowing the seasoned beef to sit for a few minutes while you prepare the remaining ingredients gives the seasonings time to adhere to the surface.

2. Wrap the Beef in Bacon

Lay the bacon slices across the roast, slightly overlapping each piece.

If necessary, tuck the ends underneath the roast or secure the bacon with toothpicks.

Don't worry if the bacon doesn't look perfectly neat. It will shrink slightly as it cooks and help coat the beef with its savory flavor.

3. Prepare the Slow Cooker

Place the bacon-wrapped sirloin in the center of the slow cooker.

Whisk together the beef broth, Worcestershire sauce, and Dijon mustard.

Pour the mixture around the roast rather than directly over the bacon. This helps keep the bacon from becoming completely submerged.

4. Cook Slowly

Cover the slow cooker and cook until the beef reaches your preferred level of doneness.

Because sirloin is a relatively lean cut, avoid assuming that a long cooking time will automatically make it more tender. Unlike tougher cuts such as chuck roast, sirloin can become dry if it is cooked well beyond its ideal temperature.

Use an instant-read thermometer to check the thickest part of the meat.

For a whole beef roast, the USDA recommends a minimum internal temperature of 145°F (63°C) followed by at least a three-minute rest.

5. Crisp the Bacon
