In this comprehensive guide, you'll discover everything from selecting the perfect cut of corned beef to mastering pressure cooking techniques. I'll also share serving suggestions, storage tips, and flavor variations to help you make this dish your own.

Why This Instant Pot Corned Beef Recipe Works

Reduces cooking time by up to 70% compared to traditional methods
Creates perfectly tender meat with minimal effort
Uses simple ingredients you likely already have in your pantry
Works with both flat and point cuts of corned beef
Allows you to cook vegetables in the same pot for a complete meal
Perfect for holiday traditions or any-day comfort food
Creates delicious leftovers for sandwiches and hash
Requires minimal hands-on attention while cooking

The Instant Pot's sealed environment and precise temperature control transform what was traditionally an all-day cooking project into a reliable weeknight option. The pressure cooking method forces moisture into the tough brisket meat, breaking down connective tissues more efficiently than any other cooking method.

Choosing the Right Corned Beef

Understanding Corned Beef Cuts

The cut of corned beef you select significantly impacts your final dish. There are two primary cuts available:

Flat Cut (First Cut): This is the leaner option with a uniform shape and consistent thickness. The flat cut is easier to slice neatly and has less fat marbling. It's ideal if you prefer cleaner slices and a leaner texture.

Point Cut: The point cut has more marbling (intramuscular fat) and generally produces a more tender, flavorful result. However, it's irregularly shaped and can be trickier to slice evenly. Choose this cut if tenderness and flavor are your top priorities.

For this Instant Pot recipe, both cuts work well. The pressure cooking environment helps even lean flat cuts become tender, while point cuts become exceptionally succulent.

Buying Tips

When shopping for corned beef, look for:

Packages with visible liquid: The brine should cover the meat
Bright pink color (indicates proper curing)
A size that fits comfortably in your Instant Pot (typically 3-4 pounds works well)
"Choice" grade or higher for better marbling and flavor
A "sell by" date that's as far in the future as possible

Many corned beef packages come with a seasoning packet. These are perfectly fine to use, but this recipe provides seasoning options if yours doesn't include one or if you prefer to create your own flavor profile.

Substitutions

If traditional beef brisket corned beef isn't available, consider:

Corned beef round: Leaner but still works well in the Instant Pot
Uncured brisket: You can add pickling spices and salt to approximate the corned beef flavor
Pre-cooked corned beef: Reduce pressure cooking time to 25-30 minutes

Ingredients & Prep

Corned Beef Essentials

3-4 pound corned beef brisket (flat or point cut)
Seasoning packet (typically included) or 2 tablespoons pickling spice
4 cups beef broth or water (broth adds more flavor)
2 bay leaves
1 teaspoon black peppercorns
3-4 cloves garlic, peeled and smashed

Optional Aromatics

1 medium onion, quartered
2 stalks celery, roughly chopped
2 carrots, roughly chopped (if not cooking vegetables separately later)
2 tablespoons brown sugar (adds subtle sweetness that balances the salt)
1/4 cup apple cider vinegar (helps tenderize the meat)

For Serving (Optional)

1 head cabbage, cut into wedges
1 pound baby potatoes
4 carrots, cut into large chunks
Fresh parsley for garnish
Whole grain mustard
Horseradish cream sauce

Prep Work

Before cooking your corned beef in the Instant Pot:

Remove the corned beef from its packaging over the sink (there will be liquid).
Rinse the meat under cold water to remove excess salt from the brine. This is an optional but recommended step that helps prevent the final dish from being too salty.
Pat the meat dry with paper towels.
If your corned beef has a very thick fat cap (more than 1/4 inch), trim it down slightly. Don't remove it entirely, as it adds flavor and moisture during cooking.

The beauty of Instant Pot corned beef is that minimal prep work is required, making this an exceptionally convenient method for cooking this traditionally time-intensive dish.

Step-by-Step Cooking Instructions

Pre-Cooking Prep

Place the trivet (metal rack) that came with your Instant Pot in the bottom of the inner pot.
If using a seasoning packet, open it and sprinkle half over the corned beef. Reserve the rest for later.
If making your own seasonings, combine the pickling spice, bay leaves, and peppercorns in a small bowl.

Cooking Method

Place the corned beef on the trivet, fat side up. Positioning the fat on top allows it to render down through the meat as it cooks.
Add smashed garlic cloves, onion quarters, celery, and carrots (if using) around the meat.
Pour beef broth or water around the sides of the meat (not directly on top, to keep the seasonings in place). Add apple cider vinegar and brown sugar if using.
Sprinkle the remaining seasoning over the top of the meat.
Close the Instant Pot lid and set the valve to "Sealing" position.
Select "Pressure Cook" or "Manual" (depending on your Instant Pot model) and set to High Pressure.
Set the cooking time based on the weight of your corned beef:
- 2-3 pounds: 70 minutes
- 3-4 pounds: 80-85 minutes
- 4-5 pounds: 90 minutes
When the cooking cycle completes, allow for a 15-minute natural pressure release (NPR). This resting period allows the meat fibers to relax, resulting in a more tender texture.
After 15 minutes, carefully release any remaining pressure by turning the valve to "Venting."

Cooking Vegetables (Optional)

If you'd like to cook traditional vegetables to serve with your corned beef:

Remove the cooked corned beef and place it on a cutting board. Tent with foil to keep warm.
Strain the cooking liquid and return 2 cups to the Instant Pot.
Add cabbage wedges, potatoes, and carrot chunks to the pot.
Close the lid, set valve to "Sealing," and pressure cook on High for 3-4 minutes.
Quick-release the pressure when complete.

Slicing and Serving

Allow the corned beef to rest for at least 10 minutes before slicing. This helps the meat retain its juices.
Identify the direction of the grain (the muscle fibers) in the meat.
Slice the corned beef AGAINST the grain (perpendicular to the muscle fibers) for maximum tenderness. Use a sharp knife and aim for medium-thin slices about 1/8 to 1/4 inch thick.
Arrange slices on a platter with the cooked vegetables if desired.
Spoon a little of the cooking liquid over the meat to keep it moist and flavorful.

Pro Tips for Perfect Instant Pot Corned Beef

Avoiding Common Mistakes

Don't skip the natural pressure release: This resting period is crucial for tender meat. Rushing this step can result in tougher corned beef.
Watch the salt: Corned beef is already salty from the brining process. Avoid adding extra salt to the cooking liquid.
Choose the right size: Select a corned beef that fits comfortably in your Instant Pot without touching the sides if possible.
Slice properly: Always cut against the grain; slicing with the grain will result in stringy, tough meat regardless of how well it's cooked.

Tool Recommendations

Meat thermometer: While not strictly necessary (the Instant Pot cooking times are reliable), an instant-read thermometer ensures your corned beef reaches the ideal temperature of 195°F for maximum tenderness.
Sharp carving knife: Makes clean slices without tearing the meat.
Large cutting board with juice groove: Captures the flavorful juices released during slicing.
Fat separator: Helpful for defatting the cooking liquid if you plan to serve it as au jus.

Storage & Reheating

Refrigeration: Store leftovers in an airtight container with some cooking liquid to keep the meat moist. Refrigerate for up to 4 days.
Freezing: Wrap tightly in plastic wrap, then foil, or place in freezer bags with a little cooking liquid. Freeze for up to 3 months.
Reheating: For best results, reheat slices gently with a little broth in a covered skillet over low heat. Microwaving is convenient but can make the meat tough.
Repurposing leftovers: Use in Reuben sandwiches, corned beef hash, or chop into salads.

Flavor Variations

Traditional Irish-Inspired

FAQs

Can I cook frozen corned beef in the Instant Pot?

While it's possible to cook frozen corned beef in the Instant Pot, it's not recommended. The seasoning won't adhere properly, and the cooking can be uneven. If you must cook from frozen, increase the cooking time by about 30% and be aware that the results may not be as tender or flavorful.

How do I know if my corned beef is done?

Properly cooked corned beef should reach an internal temperature of 195°F-205°F and feel tender when pierced with a fork. At this temperature, the collagen has broken down, resulting in meat that pulls apart easily but still holds together when sliced.

Can I overcook corned beef in the Instant Pot?

Yes, although the Instant Pot makes it less likely compared to other methods. Overcooked corned beef can become mushy and fall apart completely. Follow the recommended cooking times based on weight for best results.

Why is my corned beef tough?

If your corned beef is tough, it's typically undercooked rather than overcooked. Return it to the Instant Pot and cook for an additional 10-15 minutes if needed. Remember that the grain direction when slicing also significantly impacts perceived tenderness.

Do I need to use the seasoning packet that comes with the corned beef?

No, it's optional. The meat is already flavored from the brining process. The seasoning packet enhances the flavor but can be replaced with your own pickling spice blend if preferred.

How much corned beef should I make per person?

Plan for about 1/2 pound of raw corned beef per person, which will yield about 1/4 to 1/3 pound of cooked meat per serving. If you want leftovers (highly recommended for Reuben sandwiches!), increase to 3/4 pound raw weight per person.
