How to Make CrockPot Mississippi Pot Roast
Step 1: Prepare the Slow Cooker
Place the beef roast into your slow cooker. This will be the main component that absorbs all the flavors from the ingredients you add next.
Step 2: Add Dry Ingredients
Sprinkle the dry ranch dressing mix and au jus gravy mix evenly over the top of the roast. This creates a wonderful seasoning layer that helps flavor the beef.
Step 3: Add Peppers and Butter
Add the pepperoncini peppers and scatter the butter in several pieces on top. This combination will create a delicious sauce as it cooks.
Step 4: Cook the Roast
Cover the slow cooker and cook on low for 8 hours. The beef will become fork-tender and easy to pull apart when it is done.
Step 5: Shred and Serve
Once cooked, carefully remove the roast from the slow cooker and set it aside on a plate. Skim any excess fat from the surface of the cooking liquid if needed.
Step 6: Thicken the Gravy (Optional)
To make a thicker gravy, whisk together 2 tablespoons of cornstarch with 2 tablespoons of cold water. Stir this mixture into the cooking liquid and cook on high for about 10–15 minutes until slightly thickened.
Step 7: Combine and Enjoy
Shred the beef using two forks, then return it to the slow cooker. Stir to coat it in the sauce. Serve warm with juices spooned over the top.

Pro Tips from My Kitchen
✓ Meat Choice – Choose a well-marbled chuck roast for the best flavor and tenderness. The fat will break down during cooking, ensuring juicy meat.
✓ Spice Adjustments – Feel free to adjust the ranch dressing and au jus amounts based on your taste preference. You can reduce the seasoning for a milder dish.
✓ Wait for Tenderness – Don't rush the cooking time. The roast needs the full 8 hours on low for optimal tenderness. Check if fork-tender for the best results.
✓ Leftover Storage – Store any leftovers in an airtight container in the fridge for up to three days. Reheat gently to preserve the meat's tenderness.
✓ Plan Ahead – This recipe is perfect for meal planning. Prepare in advance and let the slow cooker do its magic while you're busy with other tasks.
