First, let’s get everything together. You want to ensure your counter is clear and your ingredients are prepped, so when the cooking starts, all you need to do is follow the steps. For this recipe, you’ll need your brisket, onion, beer, chili sauce, brown sugar, Worcestershire sauce, and the seasoning.

Set your oven to 325°F (165°C). Preheating first means you’ll have your cooking environment ready right when you need it.

Generously season the brisket on all sides with salt and pepper. Don’t skimp on this part; the seasoning helps to enhance the flavor throughout the cooking process.

In a glass baking dish, lay the seasoned brisket flat. Then, sprinkle the sliced onions on top. They will not only add flavor but also become soft and delicious throughout the cooking process.

In a medium mixing bowl, combine the beer, chili sauce, Worcestershire sauce, and brown sugar. Stir until the ingredients are well mixed, and sugar has dissolved.

Pour the mixture over the brisket, making sure it covers the meat as much as possible. This will create a luscious sauce that seeps into the brisket as it cooks.

Cover the baking dish tightly with aluminum foil. This step is crucial as it traps moisture and ensures the brisket stays juicy. Pop it into the oven and let it bake for 3 hours.

After 3 hours, take off the aluminum foil. Allow it to bake uncovered for an additional 30 minutes. This step helps to caramelize the top layer, adding a beautiful texture and flavor.

Once done, remove the brisket from the oven and let it rest for about 10-15 minutes. This resting period will help the juices redistribute throughout the meat. Then, slice it against the grain for the best result.

Return those sliced pieces to the dish with the sauce spooned over. You’ll want every slice dripping with that delightful sauce as you serve it up!
