Step 1

Add chopped onion, garlic, corned beef pickling spices, and 4 cups (1000mls) of water into your electric pressure cooker.

Step 2

Place the beef brisket on top of the onions, lock the lid, turn the steam release vent to 'sealing' and using the manual setting, adjust it to cook for 85 minutes for a 4lb brisket, 80 minutes for a 3lb brisket, and you can reduce the time further if it's smaller than that. NOTE- If your beef is thicker than 1.5 inches this may increase the cook time so add an additional 5 minutes then check and see if it's done when you take the lid off. If it's not done simply pressure cook it again for 5-10 more minutes.

Step 3

When the cook time time is up allow the unit to reduce pressure on its own without opening the steam release vent (Natural Release) for 15 minutes or until the pin drops, then open the steam release vent and carefully open the lid. If it's not fully cooked simply put the lid back on and cook a little longer.

Step 4

Take out brisket and wrap it in foil to keep warm.

Step 5

Pour out all the cooking liquid except for one cup, or if you prefer you can use water. Place the trivet that came with your Instant Pot (or use a metal steamer basket) and add the potatoes, carrots, and cabbage and close the lid. If you do not have a trivet simply add place the vegetables directly into the liquid.

Step 6

Adjust your pressure cooker to cook for 3 minutes and then open the steam release vent and carefully open the lid. If they are not fully cooked put the lid on and cook for 1 more minute.

Step 7

Slice the corned beef and serve hot with the vegetables.

Step 8

Add chopped onion, garlic, corned beef pickling spices, and 4 cups (100mls) of water into your slow cooker.

Step 9

Place the Corned Beef into the slow cooker

Step 10

Cook on low for 8-10 hours or on high. Add carrots and potatoes after 4-5hrs and add the cabbage in the last hour of cooking.
