Gather the ingredients.

Preheat the oven to 350 degrees F (175 degrees C).

Heat oil in a saucepan over medium-high heat. Cook and stir onions and garlic in hot oil until fragrant and softened, 4 to 6 minutes.

Stir in chili sauce, beer, honey, Worcestershire sauce, and dry mustard. Bring to a boil, reduce heat to low, and simmer until sauce thickens and flavors develop, about 20 minutes.

Meanwhile, arrange ribs evenly in a large baking dish. Bake ribs in the preheated oven for 1 hour.

Spread sauce over ribs and continue baking until sauce bubbles and ribs are tender, about 1 hour more.

Serve hot and enjoy!
