Preheat the oven to 350°F.
In a large bowl, toss the beef with the mustard, brown sugar, liquid smoke, garlic salt, minced onion, steak seasoning, and smoked paprika.
Place the stew beef in a 9×13 baking dish, cover with foil, and bake for 1 ½ – 2 hours or until tender.
Take out of the oven and drain off any liquid.
Toss the burnt ends in the BBQ sauce.
Turn the oven to 450°F and put them back in the oven for 15 minutes or until they are dark and caramelized “burnt”. Serve immediately.
