Choosing the Best Brisket
Brisket comes from the lower chest of the cow and contains plenty of connective tissue. While this can make it tough when cooked quickly, it becomes wonderfully tender when cooked under pressure. Look for a brisket with good marbling, as the fat helps keep the meat juicy and flavorful during cooking.
You can use either the flat cut or point cut. The flat cut slices neatly, while the point cut contains more marbling and often delivers richer flavor.
Step 1: Season and Prepare the Beef
Begin by patting the brisket dry with paper towels. Removing excess moisture helps create a better sear. Season all sides generously with salt, black pepper, smoked paprika, thyme, and rosemary.
Allow the seasoned meat to sit for a few minutes while preparing the Instant Pot. This helps the seasonings adhere to the surface and begin flavoring the meat.
Step 2: Sear the Brisket
Set the Instant Pot to Sauté mode and add the olive oil.
When the oil is hot and shimmering, place the brisket pieces into the pot in batches. Avoid overcrowding, which can prevent proper browning.
Sear each piece for approximately 3 to 4 minutes per side until a deep golden-brown crust forms. This step adds tremendous flavor to the finished dish.
Transfer the browned brisket to a plate and set aside.
Step 3: Build the Flavor Base
Add the sliced onions directly to the pot. Cook for several minutes until they become soft and lightly caramelized.
Stir in the minced garlic and cook briefly until fragrant.
Next, add the tomato paste and Dijon mustard. Stir continuously for about one minute. Cooking these ingredients before adding liquid helps deepen their flavor and creates a richer gravy later.
Step 4: Deglaze the Pot
Pour in the beef broth and Worcestershire sauce.
Using a wooden spoon, scrape the bottom of the pot thoroughly to loosen any browned bits. These flavorful bits contain concentrated savory flavor that enriches the entire dish.
Return the seared brisket to the pot.
Add the bay leaves and sliced mushrooms, ensuring the meat is partially submerged in the cooking liquid.
Step 5: Pressure Cook Until Tender
Secure the Instant Pot lid and set the pressure valve to Sealing.
Cook on High Pressure for 60 minutes.
Once the cooking cycle is complete, allow the pressure to release naturally for 15 minutes. This additional resting time helps keep the brisket moist and tender.
Afterward, carefully release any remaining pressure.
Open the lid and enjoy the incredible aroma of slow-cooked beef, herbs, onions, and mushrooms.
Step 6: Prepare the Onion Mushroom Gravy
Transfer the brisket to a serving platter and loosely tent it with aluminum foil to keep warm.
Remove and discard the bay leaves.
Switch the Instant Pot back to Sauté mode.
In a small bowl, whisk together the cornstarch and cold water until completely smooth.
Slowly pour the slurry into the simmering liquid while whisking continuously.
Allow the gravy to cook for 2 to 3 minutes, stirring frequently, until it thickens into a glossy, velvety sauce.
Taste and adjust seasoning if necessary.
Step 7: Serve and Enjoy
Slice the brisket against the grain for maximum tenderness or shred it into rustic pieces.
Arrange the meat on a serving platter and spoon generous amounts of the onion mushroom gravy over the top.
Finish with freshly chopped parsley for a burst of color and freshness.

Reheating

Helpful Tips for Success
- Always sear the brisket before pressure cooking.
