What is Mississippi Pot Roast?

Robin Chapman is the creator of the original Mississippi Pot Roast Recipe. She adapted a roast beef recipe that was too spicy for her young kids, and this was the moment the ever so famous Mississippi Roast was born.

The original Mississippi Pot Roast uses the slow cooker, including ingredients like au jus gravy mix (dry), ranch dressing mix (dry), and Pepperoncini peppers.

The ingredients & simple instructions might be a shocker, but her family & friends loved this roast, and they couldn’t stop raving about it.

This has led one of her friends to contribute this recipe into a cookbook put together by her church. And the snowball effect began.

From the little cookbook that led to being published on a food blog, then many other mom blogs, which then spread like wildfire all over the internet.

Little did she know this super simple recipe would lit the internet on fire and storm into American homes nationwide!

As much as we like to stay true to the original, we enjoy being a little “Amy & Jacky”, adding our own little zings & twists to our Instant Pot Mississippi Pot Roast Recipe. 😛

So, instead of using Dry Ranch Dressing Mix packet & Dry Au Jus Mix packet, we’re opting to mix our ownHerbs, Spices & Seasonings.

Cooking TipsforInstant Pot Mississippi Pot Roast

1. Why are we browning the chuck steak as a whole?

• Retain More Moisture: Browning the chuck steak as a whole retains more moisture due to less surface area.
• Brown Faster & Better:Since maillard reaction excels in a dry and high heat environment, the chuck steak will brown faster and better compared to cubed stew.
• Richer & Flavorful: The caramelized flavors from browning results in aricher & more flavorful dish.

2. Can I use other beef cuts for this recipe?

• Chuck roast is one of the most suitable cuts for pressure cooking. For optimal result, choose one that is well marbled!! This is very critical.
