How Long to Cook Corned Beef Brisket & Cabbage (Flat Cut) in the instant pot

Add corned beef brisket & cabbage (flat cut) (3-4 lb corned beef brisket with spice packet, submerged in 4 cups water/beer, cabbage wedges added after beef cooks) to the Instant Pot inner pot. Seal the lid and set the valve to Sealing. Select 240°F (116°C) for 85–90 mins.

Cook at 240°F (116°C) for 85–90 mins. Use 10-minute natural release.

Brisket cuts effortlessly with a butter knife; cabbage wedges are tender-sweet without disintegrating. After 10-minute natural release, carefully open the lid away from you. Let stand 15 minutes before serving.
