Pull sausages from the fridge about 10 minutes before cooking — cold links cook unevenly. Pat casings dry with a paper towel; surface moisture causes steaming instead of searing. Keep fresh links whole — do not pierce the casings or fat and juices escape, leaving dry sausage. Have an instant-read thermometer ready; visual cues alone won't confirm doneness.

Heat a medium to large skillet over medium to medium-high heat. Add a little oil if the pan isn't nonstick. Lay links in a single layer with at least 1 inch of space between them — crowding causes steaming, not browning. For fresh raw sausages: Add 1/4 inch of water, bring to a simmer over medium-high (about 5 min), then reduce to medium, cover, and cook until an instant-read thermometer reads ~130°F, about 6–8 min. Uncover, raise heat to medium-high, and cook turning occasionally until water evaporates and casings are deeply browned on all sides, about 8 more minutes. Total time: 10–16 min depending on link size. For pre-cooked or smoked sausages: Heat oil or butter over medium-high and cook, turning occasionally, until browned and heated through, about 5 min. No raw internal temp target needed — just color and warmth.

Target internal temp is 160°F for fresh raw sausages (165°F for poultry-based). Insert thermometer horizontally into the thickest part — don't rely on color alone. Once up to temp, transfer to a plate and rest 2–3 minutes before cutting. Serve with sautéed peppers, onions, beans, or rice cooked in the drippings.
