Specification: 1.5 lb boneless skinless chicken breast cut into 1-inch pieces, seared in 2 tbsp butter + 1 tbsp olive oil in a 12-inch straight-sided skillet (or 3.5-qt sauté pan) for 5–6 mins until 165°F; removed to a plate; then 8 oz dried fettuccine broken in half, 3 cups chicken broth, 1.5 cups heavy cream, 4 minced garlic cloves added to the same skillet
3-Step Execution Protocol
Preheat skillet to Medium-high sear (375°F surface) then medium simmer (200°F–210°F liquid) for the pasta stage. Prepare one-pan chicken alfredo (skillet, pasta cooked in sauce) (1.5 lb boneless skinless chicken breast cut into 1-inch pieces, seared in 2 tbsp butter + 1 tbsp olive oil in a 12-inch straight-sided skillet (or 3.5-qt sauté pan) for 5–6 mins until 165°F; removed to a plate; then 8 oz dried fettuccine broken in half, 3 cups chicken broth, 1.5 cups heavy cream, 4 minced garlic cloves added to the same skillet).
Cook for 20–22 mins total (6 min chicken sear + 14–16 min pasta simmer). Flip at the 3-minute mark for even browning.
Fettuccine is al dente with slight nutty bite in the center; sauce has thickened around the strands and coats a spoon (leaves a clear track when dragged with a finger); chicken cubes read 165°F on a Thermapen; no dry spot of pasta remains at the surface. Confirm internal temperature reaches 165°F (74°C) — USDA FSIS chicken minimum, checked on the thickest cube before removing from the pan. Rest for 5 minutes before serving.
