Easy Instant Pot Mississippi Pot Roast Recipe
Instant pots and slow cookers are at opposite ends of the spectrum, yet both yield such delicious results. Thanks to the growing popularity of Instant Pots, it's no longer necessary to reserve this kind of Sunday supper meal to weekends. Just like the pressure cookers of yesteryear, roasts can be cooked in an Instant pot in no time flat.
How to Make the Best Instant Pot Mississippi Pot Roast Recipe
What is an Instant Pot? Instant Pot is actually a brand name much like Crockpot. It's basically a reimagined and updated pressure cooker and slow cooker combination that also has the functionality of steaming, sautéing, rice cooking and warming which is why it's referred to as a multicooker. It's electronically controlled and cooks in a sealed environment resulting in a super flavorful end result.
- Ingredients you'll need to make this recipe for Mississippi Pot Roast in an Instant Pot: A 3 ½ - 4 pound chuck roast, freshly ground black pepper, fresh minced garlic, diced onion, 1 package dry Ranch salad dressing mix, 1 package au ju gravy mix, 8-10 whole pepperoncini peppers plus juice, unsalted butter, olive oil and chopped fresh parsley.
- A chuck roast will result in the most tender and flavorful option for this recipe. Due to the fat marbling in the beef it makes the flavor shine.
- You'll note when seasoning the roast before searing, there's only black pepper called for in the recipe. That's due to the fact there is ample sodium in the McCormick au jus mix and Ranch salad dressing mix and there's really no need to add more.
- The pepperoncini and juice add flavor, but they aren't spicy. They provide a nice balance to the rich flavor of the roast. If you like spice, you can add red pepper flakes or a few dashes of hot sauce to the mix.
- I give a range of 8-10 pepperoncini for this recipe. Please note, you can certainly adjust the amount adding more or less, to your taste. This is another moment when there's no need to sweat the small stuff in the kitchen.
- If you don't have an Instant Pot don't worry! You can also make this Mississippi Pot Roast recipe in a crockpot or slow roast it in the oven. See the Cook's note for both slow cooker and oven cooking instructions.
- Store leftover pot roast chilled in the refrigerator for up to 3 days. Reheat gently in a saucepan over medium heat to prevent it from drying out and becoming tough.

Can you do this with a frozen roast, and if so how much extra time?
Rule of thumb for frozen beef is high pressure for 30 minutes per pound and allow 10-15 minute natural pressure release.
Can you freeze the pot roast?
Sure, no problem.

No other liquid needed.
