Tips for success
For the best flavor, use fresh herbs rather than dried. Rosemary and thyme sprigs can be left whole during cooking and removed before serving, or you can chop the leaves and stir them into the jus.
If you prefer a thicker sauce, remove the meat after shredding and simmer the jus on the stovetop for a few minutes to reduce.
This recipe is forgiving: if the roast is larger or smaller, adjust the cooking time by about an hour per pound.
For a spicy kick, add a pinch of red pepper flakes with the garlic. The leftovers are excellent in tacos, on salads, or mixed into mac and cheese.
Variations
- Citrus Herb: Add the zest and juice of one orange to the slow cooker along with the butter. The citrus brightens the rich pork and pairs beautifully with the rosemary and thyme.
- Spicy Chipotle: Stir 2 tablespoons of chopped chipotle peppers in adobo sauce into the butter before placing it on the roast. The smoky heat adds depth without overwhelming the herbs.
- Garlic Lover's: Increase the garlic to 20 cloves and slice them instead of smashing. The garlic will melt into the jus, creating an intensely savory sauce.
- Balsamic Glaze: After shredding, stir 2 tablespoons of balsamic vinegar into the jus. The tangy vinegar cuts through the richness and adds a glossy finish.
Storage and make-ahead
- Fridge
- Store in the refrigerator in an airtight container for up to 4 days. Reheat gently with a splash of broth.
- Freezer
- Freeze for up to 3 months in a freezer-safe container. Thaw overnight in the refrigerator before reheating.
- Reheat
- Reheat in a skillet over medium heat, adding a splash of broth or water, until warmed through. Or microwave in 30-second bursts, stirring between.
Refrigerate leftover pork in an airtight container for up to 4 days. Store the jus separately or with the meat.
To reheat, warm gently in a skillet or microwave, adding a splash of broth or water to keep it moist.
The entire dish can be made a day ahead. Cook and shred the pork, then cool and refrigerate in its juices. Reheat gently on the stovetop or in the oven before serving. The flavors deepen overnight.
Serving ideas
Serve the shredded pork over whipped Yukon Gold mashed potatoes, spooning the golden jus over the top.
The creamy potatoes soak up the buttery sauce, and the herbs add a fresh note. A simple green salad or roasted vegetables round out the meal.
For a casual dinner, pile the pork onto soft rolls and serve with pickles and coleslaw. The jus can be served on the side for dipping. This dish also works well over polenta, rice, or egg noodles.

Rosemary Thyme Butter Pork Sirloin Roast

Ingredients
- 3 1/2 lb boneless pork sirloin roast
- 12 garlic cloves, smashed
- 4 fresh rosemary sprigs
- 6 fresh thyme sprigs
- 1/2 cup salted butter (1 stick)
Instructions
- Place the pork sirloin roast in the center of the slow cooker. Scatter the smashed garlic cloves over the top, then lay the rosemary and thyme sprigs evenly over the roast.
- Place the stick of salted butter directly on top of the seasoned roast. It will melt as the slow cooker heats, basting the meat.
- Cover the slow cooker and cook on low for 8 to 10 hours, until the pork is fork-tender and easily shreds. The roast should reach an internal temperature of 145°F (63°C) at minimum, but cooking longer will make it more shreddable. Let it rest for 3 minutes before slicing.
- Turn off the slow cooker. Remove the roast to a cutting board and let it rest for at least 10 minutes. This allows the juices to redistribute.
- Using two forks, shred the pork into bite-size pieces. Return the shredded meat to the slow cooker and toss with the pan jus. Serve warm, spooning extra jus over the top.
