Instant Pot Corned Beef – There’s something incredibly comforting about the aroma of simmering corned beef. Growing up, my grandmother would only make it once or twice a year—usually for St. Patrick’s Day or a big Sunday dinner. But these days, with the Instant Pot, I make this dish all year round, especially in summer when I don’t want to heat up the whole kitchen. The pressure cooker locks in flavor and tenderness while cutting hours off the traditional cooking time.
This Instant Pot Corned Beef recipe is quick, flavorful, and deeply satisfying—perfect for a summer meal prep session or a festive gathering. Served with tender potatoes, sweet carrots, and soft cabbage, it’s a one-pot wonder that checks every box: hearty, easy, and deeply nostalgic.

Instructions
Step 1: Prepare the Brisket
- Rinse the corned beef under cold water to remove excess brine.

- Place trivet inside and lay the corned beef on top.
Step 3: Pressure Cook the Corned Beef

Step 4: Add Vegetables

- Add potatoes, carrots, and cabbage to the pot. Season with salt & pepper.

Step 5: Serve

Tips for the Best Instant Pot Corned Beef
- Use the trivet: It prevents the brisket from sitting in the liquid and becoming too soft.
- Slice against the grain: This ensures tender, juicy slices.
- Let it rest: Like all meats, corned beef benefits from a 10-minute rest after cooking.
- Broil if desired: For crispy edges, place sliced beef under a broiler for 2–3 minutes.
Variations and Additions
- Spicy Twist: Add crushed red pepper flakes or jalapeño to the broth.
- Garlic Lovers: Double the garlic cloves.
- Beer Broth: Substitute 1 cup of beef broth with a bottle of Irish stout.
- Low-Carb Option: Skip the potatoes and add more cabbage or use turnips.
Make-Ahead and Storage
- Refrigerate: Store in an airtight container for up to 4 days.
- Freeze: Slice beef and wrap well. Freeze up to 2 months.
- Reheat: Gently warm in broth or microwave with a splash of water.
Serving Ideas
- Classic Plate: Serve with grainy mustard and a slice of Irish soda bread.
- Sandwiches: Layer beef on rye with sauerkraut and Swiss cheese for a quick Reuben.

FAQs
Can I cook the vegetables with the meat?
Not recommended. They’ll get too soft. Adding them after ensures perfect texture.
What if my beef isn’t tender?
Cook it longer! Some briskets need up to 90 minutes depending on thickness.
Is corned beef gluten-free?
Most are, but always check the label—especially the spice packet.
