Why You Will Love This Crock Pot Mississippi Pot Roast

• Quick prep: Ready to go in under 10 minutes, making it one of the easiest dinners to pull together.
• Few ingredients: This recipe uses just a handful of pantry-friendly items, keeping shopping and prep simple.
• Tastes even better as leftovers: Flavors deepen overnight, so the roast is excellent for lunches or reheated dinners.
• Freezes well: Cook once, enjoy twice—freeze portions for up to three months to save time on busy nights.

Ingredient Notes

See the full ingredient list with exact amounts in the recipe card below.

• Best cut of beef: Choose a 3–4 lb boneless beef chuck roast with good marbling. The fat helps break down connective tissue during long, slow cooking and yields a tender, juicy result.
• Seasoning packets: Traditional Mississippi pot roast relies on ranch and au jus packets. For extra garlic flavor, use a garlic ranch packet if you prefer. If you avoid packets, be prepared to substitute several herbs and powdered seasonings to mimic the flavor.
• Pepperoncini and juice: Start with less pepperoncini juice (about 1/4 cup) if you’re sensitive to heat; you can add more later to taste. Use mild or hotter pepperoncini depending on your spice preference.
• Salt: Salt amounts can vary depending on the seasoning packets used, so season lightly at first and adjust when serving.

Recipe Variations

• Add a splash of red wine or balsamic vinegar for extra richness.
• Toss in vegetables such as large carrot chunks, mushrooms, or small potatoes. Add vegetables after a couple of hours if you want them firmer, or add at the start for softer veggies. If you add vegetables, 1/2 cup beef broth can help, though the roast will release plenty of juices on its own.
• Use medium or spicy pepperoncini for a bolder kick.
• Choose low-sodium seasoning packets to reduce the dish’s salt content.

How To Make This Recipe

Step 1: Place the roast in the bottom of the slow cooker. Pour the pepperoncini juice and Worcestershire sauce over the meat. Sprinkle the au jus gravy mix, garlic ranch seasoning and cracked pepper (and salt if using). Arrange sliced onions around the roast.

Step 2: Place pieces of butter on top of the seasoned roast and add whole pepperoncini peppers.

Step 3: Cook on low for about 8 to 10 hours, or until the meat is fork-tender and easily falls apart. Shred or break into chunks as desired.

Step 4: If not serving right away, switch the slow cooker to the “warm” setting. Serve the roast over mashed potatoes, buttery egg noodles, or on sandwiches. Garnish with chopped parsley if desired.

Recipe Tips

• Searing is optional: Searing the roast before slow cooking adds depth of flavor but isn’t necessary. Skipping searing saves time and cleanup and still produces very tender meat.
• Shred or chunk: The roast often falls apart on its own; either shredded or larger pieces work well depending on how you plan to serve it.
• No extra liquid needed: The roast releases plenty of natural juices during cooking, creating a flavorful, gravy-like sauce without adding broth.

Storage

Store leftovers with the juices in an airtight container in the refrigerator for 3–4 days. Reheat in the slow cooker on low or warm, adding a splash of broth and a bit of butter if needed. To freeze, cool completely, transfer to a freezer-safe container, and freeze up to 3 months. Thaw overnight in the refrigerator before reheating.
