Tips & Variations
- Sear the roast first. While it’s optional, browning the roast before slow cooking adds even more flavor.
- Use a chuck roast. It’s the best cut for slow cooking because it becomes tender and shreds easily.
- Don’t skip the pepperoncini juice. A splash of the juice adds extra tang and helps balance the rich flavors.
- Cook on low when possible. Cooking low and slow gives you the most tender, fall-apart roast.
- Make it with vegetables. Add baby potatoes and carrots during the last 3–4 hours of cooking for an easy one-pot meal.
- Add more pepperoncini. If you love their tangy flavor, toss in a few extra peppers before cooking.
- Save the leftovers. Shredded Mississippi Pot Roast is delicious in sandwiches, sliders, tacos, or served over baked potatoes.

Instant pot
- Sear the Meat: Select the "Saute" function on your Instant Pot and heat some oil. Sear the chuck roast on all sides until browned. This step adds flavor to the meat.
- Add Ingredients: Once the meat is browned, add the pepperoncini peppers (with their juice), Ranch seasoning mix, au jus gravy mix, and butter to the Instant Pot.
- Pressure Cook: Pour in a little bit of beef broth or water (about 1/2 to 1 cup) to ensure there's enough liquid for pressure cooking. Then, seal the Instant Pot and set it to "Manual" or "Pressure Cook" mode for about 60-70 minutes, depending on the size of your roast and desired tenderness.
- Natural Release: Once the cooking time is up, allow the pressure to release naturally for about 10-15 minutes before doing a quick release.
Notes
For the most tender results, use a chuck roast and cook it on Low for 8 hours whenever possible. If you'd like even more flavor, sear the roast before placing it in the slow cooker, although this step is optional. Add a splash of the pepperoncini juice for extra tang, and don't rush the cooking time—pot roast becomes tender only after the connective tissue has fully broken down. Store leftovers in an airtight container in the refrigerator for up to 4 days or freeze for up to 3 months. Reheat with some of the cooking juices to keep the beef moist and flavorful
