Remove the brisket from the package, reserving the pickled spice packet. Rinse under cold water then pat dry with paper towels.
- 2
Put the onion wedges in the bowl of a slow cooker OR Instant Pot and lay the corned beef brisket on top. Sprinkle the pickled seasoning and 3 tablespoons of the brown sugar over the brisket. Pour in the Guinness and water or broth.
- 3
SLOW COOKER: Cook the brisket on high for 4 hours or on low for 6 hours.
- 4
INSTANT POT: Select pressure cooker setting; adjust pressure to high, and set time for 1 hour 25 minutes. When finished cooking, quick-release pressure according to manufacturer’s directions.

Remove any tough outer leaves from the cabbage and slice it in half. Slice each half into two pieces and remove the core. Then, slice each quarter in half so that you have 8 wedges of cabbage.

SLOW COOKER: Nestle the cabbage and carrots into the slow cooker along with the brisket. Sprinkle the vegetables with about 1 teaspoon of salt. Cook for another 2 hours on high or 4 hours on low.

INSTANT POT: Remove the cooked corn beef from the Instant Pot and place it on a baking sheet that's been lined with aluminum foil or parchment paper. Pour the liquid in the Instant Pot bowl through a strainer that's been set inside a bowl. Discard the onions and pour 1 1/2 cups of the liquid back into the Instant Pot. Add the carrots and cabbage wedges. Sprinkle with about 1 tsp salt. Select pressure cooker setting; adjust pressure to high and set time for 4 minutes.

Set the cooked corned beef on a baking sheet that's been lined with aluminum foil or parchment paper. Spread the mustard sauce over the top of the brisket. Put the brisket in the oven and let broil for 2-3 minutes, just until the mustard begins to brown in a few places.

Add the potatoes to a medium or large saucepan and add enough water to cover the potatoes by 2 or 3 inches. Stir in 3 tablespoons of salt. Set the pan over high heat. When the water begins to boil, cook the potatoes for 5-8 minutes, until just barely fork tender. Drain.
- 12
Add the butter and oil to a large skillet and set it over medium heat. When the butter has melted, add the potatoes. Sprinkle the potatoes with another teaspoon of salt and roll them around in the pan so that they are coated on all sides in butter and oil.
- 13
Cover the pan with a lid or sheet of aluminum foil, turn the heat down to low, and let cook for 20 - 25 minutes. Every once in a while, shake the pan so the potatoes roll around and do not burn. The potatoes are done when a fork pricked into one of the potatoes slides in like butter.
- 14
Remove the pan from the heat and add the chopped parsley. Stir the potatoes around in the pan to coat in the butter and parsley, then turn them out into a serving bowl.

Customization & Serving Tips
While Guinness is specified for its unique depth of flavor, the recipe notes that you can use 'any kind' of broth or water for the additional 1/2 cup liquid. If baby potatoes aren't readily available, you could substitute with other small, waxy potato varieties, cut into uniform pieces for consistent cooking. Feel free to adjust the amount of dark brown sugar in the glaze to match your preferred level of sweetness.
