Instant Pot Mississippi Pot Roast is a tantalizingly tender and richly flavored dish. It is an absolute treat for your taste buds. It's easy to make, delicious, and bursting with flavor.
While the Instant Pot heats up, cut the roast into 3-4 pieces and season it generously with salt and pepper on all sides. Add the butter to the preheated pot and allow it to melt. Carefully place the seasoned roast into the Instant Pot and sear it for 3-4 minutes on each side until it develops a beautiful brown crust.
Once the roast is seared to perfection, remove it from the Instant Pot and set it aside. Add minced garlic to the pot and sauté for about a minute until fragrant. Next, pour in the pepperoncini juice and beef broth, scraping the bottom of the pot to release any browned bits.
Return the seared roast to the Instant Pot, followed by the dry ranch dressing mix and au jus gravy mix. Scatter the pepperoncini peppers on the roast for an extra burst of flavor.
Secure the lid of the Instant Pot, ensuring that the pressure valve is set to the "Sealing" position. Select the "Pressure Cook" or "Manual" setting and adjust the cooking time to 60 minutes.
Once the cooking cycle completes, allow the pressure to release naturally for 10-15 minutes. This process ensures the juices are redistributed within the meat, making it incredibly moist and tender. Carefully remove the lid.
Using a pair of tongs or a fork, shred the pot roast into thick, juicy pieces. Serve it on a platter, drizzling the meat with the flavorful cooking liquid. Remember to garnish your creation with some tangy pepperoncini peppers.
