This slow cooker pork sirloin roast is the definition of set-it-and-forget-it cooking. With just a handful of ingredients and a few minutes of prep, you get a dinner that tastes like it simmered all day — because it did.
The pork comes out meltingly tender, the potatoes soak up all the buttery juices, and the carrots turn sweet and soft. It's the kind of meal that makes the whole house smell amazing.
Pork sirloin roast is an underrated cut that becomes incredibly succulent when cooked low and slow. Paired with baby Yukon Gold potatoes and heirloom carrots, it turns into a complete one-pot dinner.
The butter melts over everything, creating a rich, golden pan jus that coats every bite. This recipe is perfect for busy weeknights or lazy weekends — just layer the ingredients, set the slow cooker, and walk away.
Ingredients
- 3 1/2 lb boneless pork sirloin roast
- 1 1/2 lb baby Yukon Gold potatoes, halved
- 4 heirloom carrots, thick-cut
- 1/2 cup salted butter (1 stick)
- 1 tsp kosher salt
- 1/2 tsp black pepper
Why this recipe works
Slow cooking breaks down the connective tissue in the pork sirloin, turning a lean cut into fork-tender shreds. The low, gentle heat allows the meat to cook evenly without drying out. Meanwhile, the butter melts and emulsifies with the natural juices, creating a silky, flavorful sauce that bathes the vegetables and meat.
The Yukon Gold potatoes are chosen for their creamy texture and buttery flavor. They hold their shape during the long cook time while absorbing the savory juices. The carrots add a touch of sweetness that balances the richness of the pork and butter. Everything cooks together in one pot, so the flavors meld and deepen over the hours.
Notes and substitutions
Pork sirloin roast is a lean, boneless cut that's perfect for slow cooking. You can also use pork shoulder or pork butt, but you may need to trim excess fat.
The butter adds richness and helps keep the meat moist, so don't skip it. For a dairy-free version, you can use olive oil or a dairy-free butter substitute, but the flavor will change slightly.
Baby Yukon Gold potatoes are ideal because they're small and cook evenly. If you use larger potatoes, cut them into chunks.
Heirloom carrots come in a variety of colors and have a sweeter, more complex flavor than regular carrots, but any carrot works. This recipe is very forgiving — feel free to adjust the amount of vegetables to what you have on hand.
