Ingredients for Instant Pot Corned Beef and Cabbage

3 to 4 lb corned beef brisket (with spice packet)
1 large yellow onion, quartered
4 cloves garlic, smashed
4 cups beef broth
1 to 2 cups water (as needed to cover brisket partially)
1 tablespoon Dijon mustard (optional for broth depth)
1 tablespoon apple cider vinegar
1 teaspoon black peppercorns (optional)
1 bay leaf
1 medium head green cabbage, cut into wedges
4 large carrots, peeled and cut into chunks
1.5 lbs baby potatoes, halved if large
2 tablespoons butter (optional for finishing vegetables)
Fresh parsley for garnish
Mustard or horseradish sauce for serving

Instructions for Instant Pot Corned Beef and Cabbage

Prepare the brisket: Remove corned beef from packaging and rinse lightly to remove excess brine. Pat dry and set aside.
Build the flavor base: Place onion, garlic, bay leaf, peppercorns, and beef broth into the Instant Pot. Stir in apple cider vinegar and Dijon mustard for deeper flavor.
Add the brisket: Place corned beef brisket on top of the liquid mixture, fat side up for maximum tenderness. Sprinkle spice packet over the meat.
Pressure cook: Seal lid and cook on HIGH pressure for 90 minutes. Allow natural pressure release for 15–20 minutes before venting.
Rest the beef: Carefully remove brisket and cover with foil to rest. This helps juices redistribute for perfect slicing.
Cook vegetables: Add potatoes and carrots to the remaining broth in the Instant Pot. Pressure cook on HIGH for 4–5 minutes, then quick release.
Add cabbage: Place cabbage wedges into the pot and cook on HIGH pressure for 2–3 minutes. Quick release immediately to avoid overcooking.
Finish and serve: Slice brisket against the grain. Plate with vegetables and spoon a bit of broth over the top. Add butter, parsley, and mustard if desired.

Expert Tips for Perfect Results

Don’t skip natural release: It keeps the meat tender and juicy.
Slice against the grain: This ensures the beef stays soft and easy to chew.
Layer cooking stages: Vegetables cook best after the meat to prevent mushiness.
Use broth, not just water: It builds deeper savory flavor.
Let it rest: Always rest the brisket before slicing to retain moisture.

Delicious Variations

Garlic Butter Style: Melt butter with garlic and drizzle over vegetables before serving.
Spicy Kick: Add crushed red pepper flakes or a dash of hot sauce to the broth.
Beer-Braised Version: Replace 1 cup of broth with a light lager for deeper flavor.
Honey Mustard Glaze: Brush sliced brisket with honey mustard before serving for a sweet-savory finish.
