To a shallow baking dish add the sausages. Using a fork, pierce the skin of each sausage several times on each side.

Pour the entire can of beer over the top of the brats. Brats will be mostly submerged in the beer. Refrigerate the brats and beer for at least 30 minutes or up to 6 hours.

When ready to cook, drain off all the beer from the brats. (Note: because the beer was in direct contact with raw meat, it is NOT okay to consume. Be sure to discard the beer.) Evenly sprinkle the garlic powder and pepper over the top of each bratwurst.

Preheat air fryer to 390 degrees for 3 minutes. Place the seasoned bratwurst into the air fryer basket. Cook the bratwurst at 390 degrees for 5-6 minutes. Pause cooking, then turn the sausages so they brown evenly on each side. Finish cooking for an additional 5-6 minutes. Total cook time will be 10-12 minutes.

Serve the brats in Bavarian pretzel or brioche rolls or sausage buns. Top with your desired toppings, like brown or spicy mustard, sauerkraut and/or sauteed onions.
