Ingredients
- 1 (3–4 lb) beef chuck roast
- 1 packet (1 oz) ranch seasoning mix
- 1 packet (1 oz) au jus gravy mix
- 1/2 cup (1 stick) unsalted butter, cut into pieces
- 6–8 pepperoncini peppers, plus 2 tbsp juice from the jar
- 1/2 tsp black pepper
- 1 tsp garlic powder
- 2 tbsp fresh parsley, chopped, for garnish
- Mashed potatoes, buttered egg noodles, or hoagie rolls, for serving (optional)
Instructions
- Season the roast. Pat the chuck roast dry with paper towels. Sprinkle the ranch seasoning, au jus mix, and black pepper all over, pressing it into the meat with your hands.
- Load the slow cooker. Place the roast in a 6-quart slow cooker. Scatter the pepperoncini peppers around it, drizzle the pepperoncini juice over the top, and dot with the butter pieces.
- Cook low and slow. Cover and cook on LOW for 8 hours (or HIGH for 4–5 hours), until the beef is fall-apart tender and shreds easily with a fork. Avoid lifting the lid for the first 6 hours.
- Shred the beef. Transfer the roast to a cutting board and shred it with two forks, discarding any large pieces of fat. Skim excess fat from the cooking juices if you like.
- Bring it together. Return the shredded beef to the slow cooker and toss it through the buttery pepperoncini gravy. Taste and add a splash more pepperoncini juice for extra tang.
- Serve. Pile the beef over creamy mashed potatoes, buttered egg noodles, or toasted hoagie rolls, spooning plenty of that gravy over everything.
💡 Roast smarts
Chuck roast is non-negotiable — its marbling is what makes the beef shreddable and juicy; leaner cuts dry out. Do not skip the butter: it enriches the gravy and balances the pepperoncini tang. Leftovers freeze beautifully for up to 3 months — portion the beef with its juices into freezer bags for instant future dinners. For a thicker gravy, whisk 1 tablespoon of cornstarch into the juices and cook on HIGH for 20 minutes.
Common questions
Can I make Mississippi pot roast without pepperoncini?
Yes — swap in mild banana peppers, or skip them and add 2 tablespoons of apple cider vinegar for tang. The peppers add the signature zesty bite, but the roast is still delicious without them.
What cut of beef works best?
Chuck roast is the gold standard: its fat and connective tissue break down into juicy, shreddable meat. Rump roast or brisket flat work in a pinch, but expect slightly less tender results.
Can I cook it on HIGH instead of LOW?
Yes — 4 to 5 hours on HIGH gets you there. Low and slow gives the most tender texture, but high heat works fine on busy days. Every lid lift adds cooking time, so peek sparingly.
How do I store leftovers?
Refrigerate in the cooking juices for up to 4 days — the juices keep the beef moist when reheated. It also freezes well for up to 3 months.
