This slow cooker Mississippi pot roast has earned its reputation as one of the easiest, most flavorful dinners you can make with just a handful of ingredients. Tender, fall-apart beef simmers all day in a tangy, buttery gravy with a little kick from pepperoncini peppers — no chopping, no fussing, just a few ingredients dropped into the slow cooker.
It’s the kind of recipe that seems too simple to taste this good, but one bite and it’s easy to see why it’s become a slow cooker classic.
Why you’ll love this recipe
- Just a few ingredients — no long shopping list required
- Hands-off cooking — the slow cooker does all the work
- Incredibly tender — hours of slow cooking break the beef down perfectly
- Big on flavor — tangy, buttery, and a little peppery
Ingredients
- 3–4 pound beef chuck roast
- 1 packet (1 oz) ranch seasoning mix
- 1 packet (1 oz) au jus gravy mix
- ½ cup unsalted butter (1 stick)
- 6–8 pepperoncini peppers
- ¼ cup pepperoncini brine (from the jar)
Instructions
- Place the roast in the slow cooker. Set the beef chuck roast in the bottom of the slow cooker.
- Season it. Sprinkle the ranch seasoning mix and au jus gravy mix evenly over the top of the roast.
- Add the butter. Place the stick of butter directly on top of the roast.
- Add the peppers. Scatter the pepperoncini peppers around the roast, then pour the pepperoncini brine over everything.
- Slow cook. Cover and cook on low for 8 hours or high for 4–5 hours, until the beef is fork-tender and shreds easily.
- Shred the beef. Remove the roast and shred it with two forks directly in the slow cooker, or on a cutting board before returning it to the pot.
- Combine with the gravy. Toss the shredded beef with the buttery gravy that’s formed in the slow cooker, coating it evenly.
- Serve. Serve the pot roast over mashed potatoes, rice, or piled onto rolls for sandwiches, spooning extra gravy over the top.
Tips for success
- Don’t skip the pepperoncini peppers — they add a subtle tang that balances the rich, buttery gravy, without making the dish spicy.
- Adjust the number of peppers to your taste — fewer for a milder flavor, more for extra tang.
- Let the beef rest in the gravy for a few minutes after shredding so it soaks up even more flavor.
- Skim excess fat from the gravy if you prefer a leaner result, though the butter is part of what makes this dish so rich.
What to serve it with
- Creamy mashed potatoes
- Steamed rice
- Soft rolls or buns for pot roast sandwiches
Frequently asked questions
Can I use a different cut of beef? Chuck roast is ideal for its marbling and tenderness after long cooking. Rump roast is a good substitute if chuck isn’t available.
Is this dish spicy? Not really — the pepperoncini peppers add tang more than heat. For a milder version, use fewer peppers or remove the seeds.
Can I make my own seasoning instead of packets? Yes — a homemade blend of dried dill, garlic powder, onion powder, and a bit of cornstarch can substitute for ranch seasoning, and a mix of beef bouillon, garlic powder, and onion powder can stand in for au jus mix.
Can I freeze leftovers? Yes, this pot roast freezes well for up to 3 months. Store it in the gravy to keep it moist when reheated.
