Heat oil in a large pan. Add brisket and sear for 6-10 minutes per side. Remove and place in a 9x13 baking pan.
Add sliced onions to the pan you seared the brisket in. Season with salt and sauté for 15 minutes. Add beer, BBQ sauce, and apricot preserves, and cook until mixture thickens into a sauce.
Meanwhile, preheat oven to 350⁰F. Pour sauce over the brisket. Cover tightly with foil and bake for 3 hours.
Cool, slice, and reheat with the sauce (for easier slicing, slice when cold).
