Preheat oven to 325 degrees.

Season both sides of brisket with montreal steak seasoning.

Cook the meat on high heat on both sides to form a crust.

Layer in the onions to a baking pan. Add in all the garlic cloves and top with the thyme.

Mix the cola, onion soup mix, BBQ sauce, paprika, salt and pepper in a bowl.

Put the brisket in to the pan and pour the sauce over. Cover with silver foil.

Put in the oven for 2 and a half hours.

Best served as soon as possible, or if you reheat it make sure to slice before.
