Slow-Cooker Garlic Butter Pork Sirloin Roast with Potatoes and Carrots Tips, FAQ & printable recipe

Tips for success

For the best flavor, make your own garlic-herb compound butter a day ahead. Mix softened butter with minced garlic, chopped fresh parsley, thyme, and a pinch of salt.

Roll it into a log using plastic wrap and chill until firm. Then slice into medallions when ready to use. This adds a personal touch and ensures the freshest taste.

To make this recipe even easier, you can assemble everything in the slow cooker insert the night before, cover, and refrigerate. In the morning, simply place the insert in the slow cooker base and turn it on.

This is perfect for busy mornings when you want to prep ahead. Just remember to add a little extra cooking time since the ingredients start cold.

Variations

• Herb and Citrus Twist: Add the zest and juice of one orange and a sprig of fresh rosemary to the slow cooker along with the butter. The citrus brightens the rich pork and complements the herbs beautifully.
• Spicy Kick: Stir 1-2 tablespoons of your favorite hot sauce or a teaspoon of red pepper flakes into the compound butter before placing it on the roast. This adds a subtle heat that balances the buttery richness.
• Root Vegetable Medley: Replace the carrots with a mix of parsnips, turnips, and celery root, cut into similar-sized chunks. This adds earthy sweetness and variety to the dish.
• Balsamic Glaze Finish: After shredding the pork, stir in 2 tablespoons of balsamic vinegar and let it cook for another 15 minutes. The vinegar adds a tangy depth that complements the garlic and herbs.

Slow-Cooker Garlic Butter Pork Sirloin Roast with Potatoes and Carrots

Prep 15 minCook 8 hTotal 8 h 15 minServes 6

Ingredients

• 3 1/2 lb boneless pork sirloin roast
• 1 1/2 lb baby Yukon Gold potatoes, halved
• 1 lb heirloom carrots, thick-cut
• 4 oz garlic-herb compound butter, cut into 4 medallions

Instructions

1. Place the pork sirloin roast in the center of a 6-quart slow cooker. Arrange the halved baby Yukon Gold potatoes and thick-cut heirloom carrots around the roast, tucking them snugly against the meat.
2. Place the four medallions of garlic-herb compound butter evenly across the top of the pork roast. They will melt as the slow cooker heats, basting the meat and vegetables in rich, herby flavor.
3. Cover the slow cooker and cook on low for 8 hours, or until the pork is fork-tender and reaches an internal temperature of at least 145°F (63°C). The vegetables should be tender when pierced with a fork. Let it rest for 3 minutes before slicing.
4. Once the pork reaches 145°F (63°C), turn off the slow cooker and let the roast rest in the pot for at least 3 minutes. This allows the juices to redistribute, keeping the meat moist and flavorful.
5. Use two forks to shred the pork sirloin roast directly in the slow cooker. Stir the shredded meat into the buttery juices so every bite is coated in the garlic-herb gravy.
6. Spoon the shredded pork, potatoes, and carrots onto warm plates. Drizzle with extra cooking juices from the slow cooker. Serve immediately, optionally with buttered egg noodles or crusty bread.
