How to Make Slow Cooker Bacon-Wrapped Sirloin Roast
Step 1: Prepare the Roast
Pat the sirloin roast dry with paper towels. Season all sides with garlic powder, black pepper, and thyme if using. Add salt lightly because bacon can already be salty.
Step 2: Wrap the Beef in Bacon
Arrange the bacon slices around the roast, overlapping them slightly so the beef is covered as evenly as possible. If needed, secure the bacon with kitchen twine or toothpicks that are suitable for cooking, removing them before serving.
Keep in mind that bacon cooked in a slow cooker will generally remain soft rather than becoming crisp.
Step 3: Add the Onions and Broth
Spread the sliced onion across the bottom of the slow cooker. Pour in the beef broth, then carefully place the bacon-wrapped roast on top of the onions.
The broth provides moisture and helps create flavorful cooking juices. Avoid completely submerging the roast.
Step 4: Cover and Cook
Cover and cook on LOW for approximately 4–6 hours, checking the roast early because sirloin is relatively lean. Cooking time varies with the roast’s size and thickness.
For food safety, beef roasts should reach at least 145°F (63°C), followed by a 3-minute rest. Insert a meat thermometer into the thickest part of the beef, avoiding the bacon when taking the reading.
If you prefer more thoroughly cooked beef, continue cooking to your preferred doneness, but be aware that sirloin can become drier with extended cooking.
Step 5: Check the Texture
Once the roast has reached the desired temperature, carefully remove it from the slow cooker and let it rest for at least 3 minutes. For easier slicing and better juice retention, a longer rest of about 10 minutes is useful.
Remove any kitchen twine or toothpicks before slicing.
Step 6: Make a Simple Serving Sauce
Strain the cooking liquid if desired and spoon some over the sliced beef. For a thicker gravy, transfer the liquid to a saucepan and simmer it until reduced, or thicken it with a cornstarch slurry.
Because the bacon contributes salt and fat, taste the sauce before adding extra seasoning.
Step 7: Slice and Serve
Slice the roast against the grain where possible. Arrange the slices on a serving platter, spoon a little sauce over the top, and serve with your favorite side dishes.
For a crispier bacon finish, transfer the cooked roast to a broiler-safe pan and briefly broil it, watching constantly. Ensure the beef remains at a safe temperature and avoid burning the bacon.
Helpful Tips for the Best Results
Choose a roast with an even shape. A uniformly thick sirloin roast cooks more evenly and is easier to wrap with bacon.
Don’t expect crispy bacon in the slow cooker. The moist cooking environment makes bacon tender rather than crisp. A brief broil at the end can improve the texture.
Check the temperature early. Sirloin is leaner than chuck roast, and prolonged cooking can make it dry or firm.
Keep the lid closed. Frequent opening releases heat and can increase cooking time.
Use the cooking liquid. The onions and beef broth collect savory flavors as the roast cooks and can be used for a simple sauce.
Slice against the grain. Cutting across the muscle fibers helps make each slice easier to chew.
Secure the bacon safely. Remove all toothpicks and kitchen twine before serving.
Easy Variations
Garlic Herb Bacon-Wrapped Roast
Add dried rosemary and thyme with the garlic powder for a more herbaceous flavor.
Smoky Paprika Sirloin Roast
Rub the beef with smoked paprika and black pepper before wrapping it in bacon.
Onion and Mushroom Beef Roast
Add sliced mushrooms alongside the onions for extra savory flavor. Cook them in the broth beneath the roast.
Bacon-Wrapped Roast with Gravy
Use the cooking liquid to prepare a thicker gravy with a cornstarch slurry. Simmer it separately until the desired consistency is reached.
Peppery Bacon Sirloin
Add freshly cracked black pepper over the bacon before cooking for a stronger pepper flavor.
What to Serve with Bacon-Wrapped Sirloin Roast
This roast pairs well with classic side dishes that complement the rich beef and smoky bacon.
- Creamy mashed potatoes: Ideal for soaking up the beef gravy.
- Roasted carrots: Add a touch of sweetness and color.
- Green beans: Provide a fresh contrast to the rich main dish.
- Buttered egg noodles: A simple side for serving with the cooking juices.
- Roasted Brussels sprouts: Bring a savory, slightly caramelized flavor.
- Dinner rolls: Perfect for enjoying any remaining sauce.
For a complete family dinner, serve sliced roast with mashed potatoes and a green vegetable.
Frequently Asked Questions
Can I use another cut of beef?
Yes. Top sirloin or a similar sirloin roast can work, depending on its shape and thickness. Chuck roast is another option, but it has more connective tissue and generally benefits from longer cooking until tender. Adjust the cooking time and check the texture and temperature.
Will the bacon become crispy in the slow cooker?
Usually not. The covered slow cooker traps moisture, so the bacon tends to remain soft. Briefly broiling the roast after cooking can help crisp the exterior.
Can I prepare the roast ahead of time?
You can season and wrap the roast with bacon ahead of time, then refrigerate it in a covered container. Keep raw beef refrigerated at 40°F (4°C) or below and cook it within a safe storage period. Place it directly into the slow cooker only when you’re ready to cook.
Should I add water instead of beef broth?
Beef broth adds more flavor, but water can be used if needed. You may want to adjust the seasonings when using water.
Why is my sirloin roast dry?
Sirloin is relatively lean and can become dry when cooked too long. Use a thermometer, check early, and avoid treating it like a chuck roast that needs extended cooking to break down connective tissue.
Can I make gravy from the slow cooker liquid?
Yes. Strain the liquid if desired, then simmer it in a saucepan. For thicker gravy, whisk together cornstarch and cold water, add a little at a time, and simmer until thickened.
Storage and Reheating
Refrigerate leftovers within 2 hours of cooking. Store the beef and cooking juices in separate or combined airtight containers in the refrigerator for 3–4 days.
To freeze, portion the sliced beef with a little cooking liquid into freezer-safe containers. For best quality, use within 2–3 months.
Reheat leftovers until they reach 165°F (74°C). Warm gently in a covered pan with a splash of broth or cooking juices to help prevent the beef from drying out. You can also microwave individual portions, turning or stirring as needed to heat them evenly.
Final Thoughts
Slow Cooker Bacon-Wrapped Sirloin Roast is a satisfying main dish that combines savory beef, smoky bacon, and flavorful onion broth in one comforting meal. With a little preparation and careful temperature checking, you can serve a roast that feels special enough for Sunday dinner while still being manageable on a busy day.
Pair it with creamy mashed potatoes, tender vegetables, and homemade-style gravy for a hearty meal your family can enjoy together.
