The corned beef brisket is the centerpiece—look for pre-brined cuts with the spice packet included at most supermarkets. I prefer Certified Angus Beef when available for superior marbling. The cabbage should be dense and heavy for its size, with vibrant green outer leaves. Whole Foods and Costco typically stock high-quality brisket during the holiday season.

No pre-brined brisket? Use beef brisket plus a homemade spice blend (mustard seeds, coriander, allspice). Short on time? Baby carrots and pre-cut potatoes work fine. For extra depth, swap apple cider vinegar for red wine vinegar. The Dijon mustard can be replaced with whole grain mustard for a heartier texture (just strain it out before serving).

Leftovers taste even better the next day. Store in the fridge for up to 5 days or freeze for 3 months. Reheat gently on the stovetop with a splash of broth to maintain moisture. The cabbage and potatoes absorb flavors beautifully over time.

Step-by-Step Instructions for Pressure-Cooked Corned Beef and Cabbage

Master this foolproof pressure-cooker method for tender meat and perfectly cooked vegetables.

Step 1: Prepare the Corned Beef Brisket and Liquid Base

Rinse the 3 lb Corned Beef Brisket under cold water to remove excess brine from the surface. Pat it dry with paper towels—this helps prevent excess steam during cooking. Place the brisket in the Instant Pot, fat side up.

Pour in the 4 cups Beef Broth, ensuring it covers about half of the brisket. Add the 0.25 cup Apple Cider Vinegar, 2 tbsp Brown Sugar, 1 tbsp Dijon Mustard, 2 pieces Bay Leaves, 1 tsp Black Peppercorns, and 1 tsp Kosher Salt. Stir gently to dissolve the sugar and distribute the spices evenly in the liquid.

Step 2: Pressure Cook the Brisket Until Tender

Secure the Instant Pot lid, set the valve to Sealing, and cook on High Pressure for 90 minutes. The cooking time ensures the tough brisket fibers break down into fork-tender perfection while absorbing the aromatic braising liquid.

Allow the pressure to release naturally for 15 minutes after cooking completes. This gradual release prevents the meat from seizing up and becoming tough. The brisket is done when it shreds easily with a fork and the internal temperature reaches at least 195°F.

Step 3: Add Vegetables and Finish Cooking

Carefully transfer the cooked corned beef to a cutting board and cover loosely with foil. Add the 1 lb Red Potatoes (halved), 3 whole Carrots (cut into chunks), 1 whole Yellow Onion (quartered), and 1 whole Green Cabbage (cut into wedges) to the pot. Nestle the 4 cloves Garlic Cloves (smashed) among the vegetables.

Secure the lid again and cook on High Pressure for 4 minutes. The vegetables will steam perfectly in the flavorful braising liquid from the brisket. Use a quick pressure release after cooking to stop the cooking process immediately and preserve the vegetables’ texture.

Step 4: Rest, Slice, and Serve

Let the corned beef rest for 10 minutes before slicing against the grain into ½-inch thick pieces. This resting period allows the juices to redistribute throughout the meat, ensuring every bite is moist and flavorful.

Arrange the sliced corned beef on a serving platter surrounded by the cooked vegetables. Spoon some of the cooking liquid over the top for extra moisture and flavor. The cabbage should be tender but still vibrant, the potatoes fork-tender, and the carrots perfectly cooked through.

Pro Cooking Tips for Perfect Results

Liquid Ratio Matters

Never exceed ½ the Instant Pot capacity with liquid and meat combined. For this recipe, 4 cups beef broth is perfect for a 6-quart pot. Too much liquid dilutes flavors and risks overcooking the veggies. I learned this the hard way during my first St. Patrick’s attempt.

Layering Technique

Always place the 3 lb Corned Beef Brisket fat-side up in the pot. This ensures the meat stays submerged while cooking. Nestle the 1 lb Red Potatoes and 3 whole Carrots around the edges, not beneath, to prevent burning. The cabbage wedges go on top last. 💡

Natural Release Timing

Let the pressure release naturally for 15 minutes after cooking the brisket. This gradual release keeps the meat from tightening up. For the vegetables, a quick release works best to maintain their texture. I set a timer to avoid overcooking.

Spice Packet Hack

If your brisket comes with a spice packet, add it directly to the broth. For extra depth, supplement with 1 tsp Black Peppercorns and 2 pieces Bay Leaves. I also toss in a few juniper berries from my foraging stash when available.

Resting is Key

After cooking, transfer the brisket to a cutting board and rest for 10 minutes. This allows juices to redistribute. Slice against the grain into ½-inch thick pieces for maximum tenderness. The cabbage will continue cooking slightly from residual heat.

Flavor Boost

Stir 1 tbsp Dijon Mustard and 2 tbsp Brown Sugar into the broth before cooking. The mustard adds tang while the sugar balances the acidity. A splash of 0.25 cup Apple Cider Vinegar at the end brightens all the flavors beautifully. 🔥
