Place Boston Butt Roast in the crock pot and make sure the pork is patted dry of any moisture and room temperature before prepping. Place the Boston butt roast and cook it fatty side up.
Cut little holes in the roast with a knife all over the front and back of the roast. Nestle the slivers of garlic into the holes you created and into any of the nooks and crannies already in the roast.
Add half of the seasoning and olive oil on one side of the roast and massage in. Then, flip over the roast fatty side up and season the second side and massage it all in.
Slice up one onion and scatter on top. (the fatty side should be facing up)
Squeeze over the juice of 1 lemon and then quarter another lemon and add directly into the crock pot.
Cover and set the crock pot to high and cook about 5-6 hours or until he roast is very moist and almost falls apart.
Serve this roast up over white rice and spoon over the juices on top of the rice and the pork. Serve with a side salad night one! Enjoy!
