1: Preheat oven to 300F. Line a baking sheet with parchment paper. Place your brisket in.
2: Start by heating a pan over medium high heat. Add oil and sauté onions until soft and dark. Add beer, maple syrup, and garlic. Sauté for a few more minutes.
3: Pour sauce over brisket. Add bay leaves and salt.
4: Cover and bake for 8-8.5 hours. Keep checking and basting it. Once a fork goes in easily, it's ready.
5: Cool before slicing.
