Heat olive oil in a pan over medium-high heat. Sear the pork roast on all sides until browned.
Place the sliced onions, garlic, carrots, and potatoes in the bottom of the crock pot.
Add the seared pork roast on top of the vegetables.
In a small bowl, mix chicken broth, soy sauce, Worcestershire sauce, thyme, rosemary, paprika, salt, and black pepper.
Pour the mixture over the pork and vegetables in the crock pot.
Cover and cook on LOW for 8 hours or HIGH for 4 hours until the pork is tender and easily shreds.
For a thicker gravy, remove 1/2 cup of the cooking liquid and mix with cornstarch, then stir back into the crock pot.
Shred the pork and serve with the vegetables and sauce.
