Pour 4 cups of water into the bottom of a 6-quart or larger Instant Pot. Place the corned beef brisket inside with the fatty side down if present. Sprinkle the spice packet and place the lightly smashed garlic cloves on top of the brisket. In a bowl or large ziplock bag, toss baby red potatoes and baby carrots with olive oil and garlic salt, then arrange them around the brisket inside the pot.

Once cooking is complete, allow the Instant Pot to naturally release pressure for about 10 minutes, then manually release remaining pressure. Carefully remove the lid. Transfer carrots and potatoes to a serving platter and cover with foil to keep warm. Place corned beef on a cutting board and allow to rest for 5 minutes.

Slice the corned beef against the grain and arrange it on top of the potatoes and carrots. Serve immediately alongside the Irish coleslaw.
