Why This Method is Better (My Pro-Tips)
Most recipes just tell you to dump everything in. We’re going to build flavors. We start by toasting the spices.
This wakes up their oils. It fills your kitchen with an aroma that store-bought spice packets can’t match. It’s a simple step with a huge payoff.
We also sear the brisket first. This creates a flavorful crust. That crust then melts into the buttery broth during cooking.
Every step has a purpose. That’s how you get a result that’s truly special.
The “Upgraded” Ingredient List
- 1 (3-4 lb) raw corned beef brisket, with its spice packet
- 2 tbsp unsalted butter
- 1 whole head of garlic, cloves peeled and smashed
- 1 cup low-sodium beef broth
- 1 tbsp fish sauce (the secret!)
- 1 tbsp whole black peppercorns
- 2 bay leaves
- 1 small yellow onion, cut into wedges
- 1 lb small potatoes (like Yukon Gold), for serving
- 1 small head of green cabbage, cut into wedges, for serving
The Pro-Method (Step-by-Step)
Follow these steps closely. This is where the magic happens.
- Take the brisket from its package. Rinse it well under cold water and pat it very dry with paper towels. This is key for a good sear.
- Set your Instant Pot to “Sauté” on “More” or “High.” Add the butter. Once it’s foaming, add the smashed garlic cloves. Cook for 60-90 seconds until fragrant and just starting to turn golden. Scoop them out and set aside.
- Add the brisket, fat-cap down, to the hot butter. Sear for 4-5 minutes until a deep brown crust forms. Flip and sear the other side for another 4 minutes. Remove the brisket.
- Pour in the beef broth. Use a wooden spoon to scrape up all the browned bits from the bottom. This is pure flavor. Turn off the “Sauté” function.
- Add the fish sauce, peppercorns, bay leaves, and the spice packet from the brisket to the pot. Stir it all together.
- Place the onion wedges in the broth. Set the seared brisket on top of the onions. Pour the reserved garlic and any butter over the meat.
- Secure the lid. Set the valve to “Sealing.” Cook on High Pressure for 90 minutes. Let the pressure release naturally for 15 minutes, then do a quick release for any remaining pressure.
- Carefully remove the brisket to a cutting board. Tent it loosely with foil. Let it rest for 10 minutes.
- While it rests, add the potatoes and cabbage wedges to the hot broth in the pot. Cook on High Pressure for 4 minutes. Quick release the pressure. Your sides are done.
- Slice the brisket against the grain. Serve it with the potatoes, cabbage, and a generous ladle of that incredible garlic butter broth from the pot.
Common Mistakes & How to Fix Them
Even advanced cooks can slip up. Here’s how to avoid two big ones.
Mistake 1: Not rinsing the brisket. The brine it’s packed in is extremely salty. If you don’t rinse, your final dish will be inedible. Always rinse and pat dry.
Mistake 2: Slicing with the grain. This gives you tough, stringy meat. Find the direction of the muscle fibers and cut straight across them. You’ll get tender, perfect slices every time.
Variations for the Adventurous Cook
Mastered the base recipe? Try these pro swaps.
Swap the fish sauce for an equal amount of Red Boat shrimp paste. Use just half a teaspoon. It adds an even deeper, funky complexity.
After cooking, reduce the broth on “Sauté” until it’s syrupy. Whisk in another 2 tbsp of cold butter to finish. This creates a rich, glossy sauce to pour over everything.

Your Pro-Level Questions Answered
Let’s tackle the advanced questions I get in my DMs.
Can I use a different cut of meat?
Stick with the packaged corned beef brisket for this recipe. Its unique curing is what we’re building on. A regular brisket won’t have the same flavor or texture.
My broth is too salty. What now?
If it’s too strong, dilute it with a half cup of hot water before adding your veggies. Next time, use a low-sodium broth and make sure you rinse the brisket well.
How do I get a crispy crust after pressure cooking?
Place the sliced beef on a sheet pan. Broil it for 2-3 minutes. Brush it with a little of the garlic butter broth first for extra flavor.
A Few Final Secrets
This dish gets better the next day. The garlic butter flavor soaks in even more.
Save every drop of that cooking liquid. Use it to cook rice or braise greens. It’s liquid gold in your kitchen.
Now you have the real secret. It’s not just a recipe. It’s a method that will change how you see your pressure cooker.
