Mississippi Roast Ingredients

This Mississippi pot roast recipe is made up of just a few simple ingredients!

  • Marinade – Head Country All-Purpose Marinade infuses so much flavor into the meat.
  • Boneless Chuck Roast – We like to use chuck roast beef, but any tough meats from well-worked muscle groups work great.
  • Salt – coating the beef in salt adds flavor and helps draw out the moisture for a more tender texture. We always use kosher salt.
  • Cooking Oil – any cooking oil will work.
  • Red Wine – adds moisture and a touch of warm sweetness to the beef. We’re also using it to deglaze the instant pot to prevent a burn notice from occurring.
  • Onion Flakes, Garlic, and Chives – create a sweet and bright flavor base for the cooking liquid. Alternatively, some people love using dry Ranch dressing mix in the packet or dry onion soup mix. Just watch the salt in these.
  • Low-sodium Beef Broth – infuses the meat with tons of moisture and flavor.
  • Pepperoncini peppers – you can usually find pepperoncini peppers in jars in the condiment aisle next to the pickles and at your local market.

How to Make Mississippi Pot Roast in the Instant Pot

First, place the beef into a resealable bag, then pour the marinade over top. Seal, then marinate for 8 hours.

Remove the beef from the marinade and pat it dry. Season with salt. Set your instant pot to “SEAR” or hit the saute button, add the oil, then brown the beef for 3-5 minutes per side. Add the wine and use a wooden spoon to scrape the browned bits from the bottom.

Add the onion flakes, garlic, black pepper, parsley, chives, and broth. Place roast back in, then top with pepperoncini peppers. Set the instant pot to pressure cook and cook for 45 minutes.

Vent the steam naturally for 15 minutes, then manually quick release the rest, then let the beef roast rest for 5 minutes. After resting, use two forks to shred the beef, then serve! 

What to Serve With This Beef Roast Recipe

Our favorite way to serve this Mississippi pot roast is over a pile of mashed potatoes topped with additional pepperoncini peppers. We also like to bulk up this meal with roasted carrots or green beans.

It’s also delicious served over rice or cauliflower rice or as a sandwich on a hearty hoagie roll.

Leftovers & Reheating

Leftover roast will last in an airtight container in the fridge for up to 4 days.

To reheat, spoon out the desired portion and warm in a skillet over low heat or in 30-second bursts in the microwave until heated through.

Girl Carnivore Pro Tip: Any of the tough meats from the well-worked muscle groups are your best choice for braising and roasting. If you’re looking for something with a huge beef flavor, try the neck or beef cheeks!
