Three-Packet Butter Pork Sirloin Roast: Easy Crockpot Dinner

This three-packet butter pork sirloin roast is the ultimate set-it-and-forget-it dinner. With just five ingredients and five minutes of prep, you can have a tender, savory roast that tastes like you simmered it all day—because you did.

The combination of ranch, Italian, and brown gravy seasonings creates a rich, herb-infused gravy that coats every shred of pork. A stick of butter melts into the pot, making the meat unbelievably moist and flavorful.

This recipe is a classic 'dump and go' slow cooker meal. You simply place a pork sirloin roast in the Crockpot, sprinkle over three packets of seasoning—ranch, Italian, and brown gravy—and top it with a stick of butter. Then you walk away.

After hours of low, slow cooking, the pork becomes fork-tender and bathes in a rich, buttery gravy. It's perfect for busy weeknights, Sunday suppers, or any time you want a hearty dinner without spending hours in the kitchen. The result is a dish that tastes like you fussed, but you didn't.

Ingredients

Why this recipe works

Slow cooking is the secret to transforming a lean cut like pork sirloin into a melt-in-your-mouth roast. The low heat and long cooking time break down the connective tissues, making the meat tender and juicy.

The three seasoning packets—ranch, Italian, and brown gravy—each bring something unique: ranch adds creamy herbs, Italian adds zesty garlic and oregano, and brown gravy provides deep, savory umami. Together, they create a complex flavor profile that you'd think required a dozen ingredients.

The stick of butter is the finishing touch. As it melts, it emulsifies with the juices released from the pork and the seasonings, creating a silky, golden pan jus that coats every bite. This is not just a roast; it's a self-basting marvel. The butter also helps keep the lean pork moist, preventing it from drying out during the long cook. The result is a dish that's rich, satisfying, and full of flavor, with minimal effort.

Notes and substitutions

Pork sirloin roast is a lean, boneless cut that's ideal for slow cooking. It's often more affordable than other roasts but becomes incredibly tender when cooked low and slow.

You can substitute pork shoulder or pork butt for even more richness and tenderness, but you may need to increase the cooking time. If you can't find pork sirloin, a boneless pork loin roast will work, but be careful not to overcook it, as it can dry out more easily.

The three seasoning packets are the heart of this recipe. Use any brand you like; the flavor will still be delicious. For a gluten-free version, check the labels for gluten-free seasoning mixes. If you prefer to control the sodium, you can use reduced-sodium versions or make your own seasoning blends. The butter should be salted for the best flavor, but unsalted butter plus a pinch of salt will also work.

• pork sirloin roast: pork shoulder or pork butt (will be even more tender but may need extra time)
• salted butter: unsalted butter plus 1/4 teaspoon salt
