How Long to Cook Fresh Bratwurst (Uncooked Pork Links, Beer-Braise + Sear) in the cast iron
Specification: 5 uncooked fresh bratwurst links (about 1.25 lb total), 5-to-a-pound size, pierced twice per link with a fork before cooking
3-Step Execution Protocol
Heat cast iron skillet over Medium-high sear (surface ≈375°F) → simmer in beer → return to sear until lightly smoking. Prepare fresh bratwurst (uncooked pork links, beer-braise + sear) (5 uncooked fresh bratwurst links (about 1.25 lb total), 5-to-a-pound size, pierced twice per link with a fork before cooking).
Cook for 18–22 mins (3 mins initial sear per side, 10 mins covered simmer in 12 oz beer, 2 mins final sear to re-crisp). Flip at the 3-minute mark for even browning.
The casings have gone from pale pink to a burnished mahogany with visible sear marks; a probe pushed into the thickest link end reads 160°F, and juices that bead at the fork holes run clear rather than pink. Confirm internal temperature reaches 160°F at the thickest part — USDA FSIS fresh pork sausage safe minimum. Rest for 3 minutes before serving.
USDA FSIS 160°F minimum internal temperature for fresh (raw) pork and beef sausage links — no rest allowance, must hit temperature during the cook. Sear-poach-sear method per Johnsonville "Bratwurst Cooking Instructions" (official guide) and Serious Eats "The Best Way to Cook Brats" reference; beer-braise volume calibrated to 12 oz per five links so the liquid covers the bottom half of the sausages only, preventing the casings from splitting.
