Creating the perfect Mississippi Pot Roast is simple when you follow these easy steps:

1. Prepare the Meat: Season the chuck roast with salt and black pepper on both sides.
2. Sear the Meat (optional): In a large skillet, heat a little oil over medium-high heat. Sear the roast for 3-4 minutes on each side until browned. This step adds flavor but is optional.
3. Place in Slow Cooker: Transfer the roast to the slow cooker.
4. Add Seasonings: Sprinkle the ranch dressing mix and au jus gravy mix evenly over the roast.
5. Add Liquids: Pour the beef broth and add the pepperoncini peppers along with their juice over the roast. If using, add the sliced bell peppers.
6. Cook: Cover the slow cooker and cook on low for 8 hours, or high for 4 hours. If cooking in the oven, place covered in a 325°F (163°C) oven for 3-4 hours.
7. Check for Tenderness: The roast is done when it’s fork-tender and easily shreds with a fork.
8. Shred the Meat: Remove the roast from the slow cooker. Use two forks to shred the meat, returning it to the cooker to mix with the juices.
9. Serve Warm: Let the roast sit for a few minutes to absorb the flavors before serving.

By meticulously following these instructions, you’ll create an incredible Mississippi Pot Roast that’s bursting with flavor and tenderness.
