Who says a show-stopping roast has to be complicated? This slow cooker bacon-wrapped sirloin turns a simple cut of beef into a tender, juicy centerpiece. The bacon wraps around the beef and bastes it as it cooks, so every slice stays moist.
The flavor is sweet, savory, and a little smoky. Brown sugar and Dijon mustard form a glossy coating, while garlic and smoked paprika add a deep, comforting taste. The beef turns fork-tender, and the bacon becomes rich and soft.
This recipe needs about 20 minutes of hands-on time. The slow cooker does most of the work. It suits busy weeknights and special occasions alike, and it is beginner friendly.

Ingredients
- 2 to 2½ lb beef top sirloin roast, tied with kitchen twine. Ask your butcher to tie it for you if needed.
- 1 tsp kosher salt
- 1 tsp black pepper, freshly ground
- 1 tsp smoked paprika
- 1 tsp garlic powder
- 2 tbsp brown sugar. Maple syrup works as a substitute.
- 1 tbsp Dijon mustard. Any mild mustard can stand in.
- 1 tbsp olive oil
- 8 to 10 slices thick-cut bacon. Thick-cut bacon holds up better during slow cooking.
- ½ cup beef broth. Use low-sodium broth to control saltiness.
Kitchen Equipment
- 6-quart slow cooker
- Large skillet
- Cutting board and sharp knife
- Kitchen twine
- Toothpicks
- Small mixing bowl
- Instant-read meat thermometer
- Baking sheet and broiler (optional)
Step-by-Step Instructions
- Pat the sirloin dry with paper towels. Tie it with kitchen twine every 1½ inches so it holds its shape.
- In a small bowl, mix the salt, pepper, smoked paprika, and garlic powder. Rub the mixture over all sides of the roast.
- Stir the brown sugar and Dijon mustard together. Spread the mixture evenly over the top and sides of the beef.
- Heat the olive oil in a large skillet over medium-high heat until it shimmers. Sear the roast for 2 to 3 minutes per side until browned.
- Wrap the bacon slices around the roast, overlapping them slightly. Secure the ends with toothpicks.
- Place the roast in the slow cooker and pour the beef broth around it, not over the bacon. Cover and cook on low for 4 to 5 hours.
- Check the roast after 4 hours. It is ready when the center reaches 135°F for medium-rare or 140°F for medium.
- Move the roast to a baking sheet. Remove the toothpicks. Broil for 2 to 4 minutes until the bacon turns crisp. Watch it closely so it does not burn.
- Rest the roast for 10 minutes, loosely covered with foil. Remove the twine, then slice against the grain into ½-inch pieces.
- Spoon the warm cooking juices over the slices before serving.
Expert Tips
- Check the temperature early. Sirloin can dry out if it cooks too long, so start checking at 4 hours.
- Dry the meat well. A dry surface helps the seasoning stick and the sear develop color.
- Choose thick-cut bacon. It stays meaty and does not fall apart in the slow cooker.
- Pair with sturdy vegetables. Carrots, potatoes, and onions hold their shape well.
- Use a meat thermometer. It takes the guesswork out of doneness.
Variations
- Spicy version: Add ½ tsp cayenne pepper to the seasoning rub.
- Maple glaze: Swap the brown sugar for maple syrup for a richer sweetness.
- Low-carb version: Skip any potato or bread side and serve with roasted green beans.
- Air fryer finish: After slow cooking, crisp the bacon in an air fryer at 400°F for 3 to 4 minutes.
- Kid-friendly version: Use turkey bacon for a milder flavor and cut the slices into smaller pieces.
What to Serve With
- Sides: Mashed potatoes, buttered egg noodles, roasted carrots, or a crisp green salad.
- Drinks: Iced tea, sparkling water with lemon, or a medium-bodied red wine.
- Desserts: Apple crisp, vanilla ice cream, or a simple fruit salad.
Storage
Refrigerator: Store leftover beef and juices in an airtight container for up to 3 to 4 days.
Freezer: Wrap slices tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
Reheating: Warm the slices gently in a covered skillet with a splash of broth. Heat only until warmed through to keep the beef tender.
Frequently Asked Questions
Can I use a different cut of beef?
Yes. Eye of round or chuck roast also works, though chuck may need a little longer to become tender.
Do I need to sear the roast first?
Searing adds color and flavor. You can skip it if you are short on time, but the result will be less rich.
Why is my bacon not crispy?
Slow cooking softens the bacon. Broiling for a few minutes at the end brings back the crunch.
Can I make this without a slow cooker?
Yes. Roast it in a 325°F oven until the center reaches your target temperature, then broil the bacon.
How do I keep the beef from drying out?
Use the broth, check the temperature early, and let the roast rest before slicing.
Can I prepare it ahead of time?
Yes. Season and wrap the roast the night before, then refrigerate it. Add it to the slow cooker the next morning.
