Preheat your oven to 375F.
Heat a dutch oven over medium high heat.
Coat the entire roast with the blackening seasoning.
Melt the dairy free margarine or oil in the dutch oven and sear the pork roast on all sides.
Cover the roast and put the pan in the oven for about 1 hour and 30 minutes for a roast that’s closer to 3 pounds and 1 hour 45 minutes to 2 hours for a larger roast.
Allow to cool before slicing.
Freezer Friendly: Leftover cooked pork roast can be shredded and frozen in plastic container or baggie. Thaw, reheat, mix with some BBQ sauce to make shredded BBQ pork sandwiches.
