Tips for success

For the best flavor, sear the pork roast in a hot skillet with a little oil before adding it to the slow cooker. This adds a deep, caramelized crust that enhances the overall taste.

However, if you're short on time, you can skip this step—the slow cooker will still produce deliciously tender pork.

Don't be afraid to customize the vegetables. While bell peppers and onions are classic, you can also add sliced mushrooms, carrots, or even a handful of cherry tomatoes in the last hour of cooking.

The key is to keep the vegetable layer thick enough to support the roast and create plenty of sauce.

Variations

Spicy Chipotle: Add 1-2 chipotle peppers in adobo sauce, minced, along with the butter. This adds a smoky, spicy kick that pairs well with the sweetness of the peppers and onions.
Citrus Herb: Swap the garlic-herb butter for a citrus-herb butter by mixing softened butter with lemon zest, orange zest, thyme, and garlic. This bright, fresh flavor is perfect for spring.
BBQ Pulled Pork: After shredding the pork, toss it with your favorite barbecue sauce and serve on buns with coleslaw. Omit the egg noodles and serve as a sandwich.
Taco Night: Shred the pork and serve in warm tortillas with diced onions, cilantro, and a squeeze of lime. The garlic-herb butter adds a unique twist to classic tacos.

Storage and make-ahead

Fridge: Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently, adding a splash of broth or water if needed.
Freezer: Freeze the shredded pork and sauce in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheat: Reheat in a saucepan over medium-low heat, stirring occasionally, until warmed through. Add a little broth or water if the sauce has thickened.

Store any leftover pork and vegetables in an airtight container in the refrigerator for up to 4 days. The flavors will continue to meld, making it even more delicious the next day.

Reheat gently in the microwave or on the stovetop, adding a splash of water or broth if the sauce has thickened too much.

You can assemble the entire dish the night before: place the seasoned pork, peppers, onions, and butter in the slow cooker insert, cover, and refrigerate. In the morning, simply place the insert in the slow cooker and cook as directed. This is a great time-saver for busy mornings.

Serving ideas

Serve the shredded pork over a bed of warm buttered egg noodles, as shown in the video. The noodles soak up the flavorful gravy, making every bite satisfying.

You can also serve it over mashed potatoes, rice, or even on crusty rolls for a pulled-pork sandwich. For a lighter option, serve it alongside a simple green salad or roasted vegetables.

To finish the dish, sprinkle with fresh chopped parsley or chives for a pop of color and freshness. A side of crusty bread is perfect for sopping up any remaining sauce. This is a meal that's meant to be enjoyed with family and friends, and it's sure to become a weeknight favorite.

Frequently asked questions

Can this recipe be made ahead of time?

Yes, the entire dish can be assembled the night before and stored in the refrigerator. In the morning, place the insert in the slow cooker and cook as directed. The cooked pork also keeps well in the refrigerator for up to 4 days, making it great for meal prep.

Can this recipe be frozen?

Absolutely. Let the cooked pork and sauce cool completely, then transfer to a freezer-safe container. It can be frozen for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stovetop or in the microwave.

What is the best cut of pork for this recipe?

Pork sirloin roast is ideal because it's lean and becomes tender with slow cooking. You can also use pork shoulder or butt, but you may need to increase the cooking time. The key is to cook until the meat is fork-tender.

Can you use chicken instead of pork?

Yes, boneless, skinless chicken thighs would work well. Cook on low for 4-6 hours or until the chicken is cooked through and tender. Shred and serve the same way.

Why is your pork dry?

Pork sirloin is lean, so it can dry out if overcooked. Make sure to cook on low and check for doneness early. The meat should be fork-tender and easily shred—if it's tough, it needs more time. Also, don't forget to let it rest before shredding.

Sweet Pepper Garlic Butter Pork Sirloin Roast

Prep 10 minCook 8 hTotal 8 h 10 minServes 6

Ingredients

3 1/2 lb boneless pork sirloin roast
3 bell peppers (red and green), sliced into thick strips
2 yellow onions, sliced
4 oz garlic-herb compound butter (cowboy butter), cut into medallions
12 oz buttered egg noodles, for serving

Instructions

Place the pork sirloin roast in the center of a 6-quart slow cooker. Scatter the sliced bell peppers and onions evenly over and around the roast, creating a bed of vegetables.
Place the medallions of garlic-herb compound butter on top of the roast, distributing them evenly so they melt over the meat as it cooks.
Cover the slow cooker and cook on LOW for 8 hours or on HIGH for 4-5 hours, until the pork is tender and shreds easily with a fork. Let it rest for 3 minutes before slicing.
Once the pork is fork-tender, transfer it to a cutting board. Let it rest for at least 3 minutes, then shred it with two forks, discarding any large pieces of fat.
Spoon the shredded pork and peppers over warm buttered egg noodles. Ladle some of the garlic-herb butter gravy from the slow cooker over the top.
