Start the slow cooker on low.
Heat a pan over high heat with a drizzle of oil. Do not season the pork yet — spices will burn on a hot sear.
Using tongs, sear all sides of the pork loin. Place a side down and let it sit until browned — if using stainless steel, wait until it naturally releases from the pan. Rotate through all sides. If the fat cap starts to render and crisp, that’s bonus flavor.
Transfer the seared pork directly to the slow cooker.
In the same pan, brown the chopped onion and add to the slow cooker.
Pour over the pork one at a time: beef broth, honey, soy sauce, vinegar, and balsamic orange glaze if using. Squeeze the oranges over the pork, then nestle the halves around it in the slow cooker. Add garlic, paprika, black pepper, thyme, and rosemary.
Cook on low for 6-8 hours until fork tender. Start fat cap up and flip every 2 hours if possible to help the meat cook evenly in the juices. Remove and discard the orange halves near the end.
When done, set the pork aside and reserve the braising liquid.
Plate the mashed potatoes, top with poblanos, then lay the pork over everything. Depending on how tender the pork ended up, slice it or pull it apart. Be liberal with the sauce — the mashed potatoes are there to catch the pork and soak it all up.
