Instant Pot Pork Roast with Herbs and Onion Gravy

This pressure cooker pork roast delivers restaurant-quality results in just over an hour. The meat is seared first to develop rich flavors, then pressure cooked with aromatic herbs, garlic, and onions that transform into a savory gravy. The high-pressure environment breaks down tough fibers while keeping the roast incredibly moist. Perfect for busy weeknight dinners or Sunday family meals when you want tender, flavorful pork without hours of traditional roasting. The natural pressure release ensures the meat stays juicy and slices beautifully.

Strain the cooking liquid and reduce it on sauté mode for a thicker gravy consistency
