Preheat oven to 225°F. Mix the salt, pepper, garlic powder, and dried rosemary together.
Pat the roast dry and rub the seasoning into the pork.
Heat oil in a 5 quart Dutch oven or larger over medium high heat.
Once hot, sear the roast on all sides.
Remove the roast from the Dutch oven and set aside. Drain any remaining oil.
Add the onions, carrots, and potatoes to the pot. Toss in the bay leaves.
Nestle the roast into the vegetables.
Mix one packet of the soup mix into the broth.
Pour in the broth then sprinkle the remaining packet over the top of the roast. P
ut roast in the oven and cook 6 hours or until the internal temperature reaches 145°F and the desired tenderness has been reached.
Add Dutch oven covered to oven and let go for 6-8 hours.
Once done, remove the roast and allow it to rest for at least 5 minutes before serving.
Notes
Trim the Fat Cap: You want some marbling, but trim any thick fat cap so the seasoning makes direct contact with the meat.
Cook by Temp, Not Time: Cooking times are approximate. Use a probe thermometer and pull the roast at 145°F for sliceable pork, or 190°F and above for pull-apart shredded pork.
Avoid the Bone: When taking the temp on a bone-in roast, don't let the probe touch the bone. It'll read falsely high.
Make a Gravy: The cooking liquid becomes a rich, flavorful gravy. Strain, thicken with a flour and butter slurry, and pour it over everything.
Cook Quicker: In a rush? Roast at 350°F for 2 to 3 hours (cook to 145°F internal) instead of the 225°F low and slow method.
Use Ground Rosemary: Dried rosemary needles stay sharp even after cooking. Grind them in a mortar and pestle or spice grinder for a smoother texture.
