The Best Mississippi Pot Roast for a Comforting Dinner

Mississippi Pot Roast is one of those weeknight heroes that tastes like you fussed but takes almost no effort. You toss a few pantry staples into a pot with a chuck roast and let time do the magic. The result is juicy, fall-apart beef with a buttery, slightly tangy kick and just the right amount of heat.

It’s a crowd-pleaser, a family favorite, and a meal that feels like a warm hug. Serve it over mashed potatoes, rice, or soft rolls and watch plates get cleared fast.

What Makes This Special

This roast is famous for being ridiculously easy and reliably delicious. You don’t need to sear anything, make a gravy, or whisk a sauce.

The combination of ranch seasoning, au jus mix, butter, and pepperoncini creates a balanced flavor that’s savory, tangy, and rich without being heavy. Unlike traditional pot roasts, this one leans into bold flavor with minimal ingredients. It also scales well, reheats beautifully, and works in the slow cooker, oven, or Instant Pot.

In other words, it’s low effort, high reward.

What You’ll Need

3–4 pounds beef chuck roast (bone-in or boneless)
1 packet ranch seasoning mix (about 1 ounce)
1 packet au jus gravy mix (about 1 ounce) or brown gravy mix
1/2 cup unsalted butter (1 stick), cut into pieces
6–10 whole pepperoncini peppers (plus a splash of the brine)
1/2 cup beef broth (optional but helps with moisture)
Freshly ground black pepper (to taste)
Optional add-ins: sliced onions, garlic cloves, baby carrots, or small potatoes

How to Make It

Prep the roast. Pat the chuck roast dry and season lightly with black pepper. No need for salt; the seasoning packets and butter bring plenty.
Layer in the pot. Place the roast in a slow cooker (or Dutch oven). Sprinkle the ranch seasoning and au jus mix evenly over the top.
Add the flavor makers. Dot the roast with butter pieces.Scatter the pepperoncini around and toss in a tablespoon or two of the brine. Pour in the beef broth if using.
Cook low and slow. For slow cooker: cover and cook on low for 8–9 hours or on high for 4–5 hours, until fork-tender. For oven: cover tightly at 300°F for about 3.5–4 hours.For Instant Pot: cook on High Pressure for 60–70 minutes, natural release 15 minutes.
Shred and mingle. Remove the roast and shred with two forks. Return the meat to the pot and toss with the flavorful juices. Taste and adjust with more pepperoncini brine if you want extra tang.
Serve it up. Spoon over mashed potatoes, buttered noodles, rice, or pile onto toasted rolls with a spoonful of the juices.

Keeping It Fresh

Leftovers keep well and might even taste better the next day.

Store the shredded beef and juices together for maximum moisture.

Refrigerate: Up to 4 days in an airtight container.
Freeze: Up to 3 months. Cool completely, pack with plenty of cooking liquid, and label.
Reheat: Gently on the stovetop or in the microwave, adding a splash of broth if needed. Stir to redistribute the fat and juices.

Why This is Good for You

Comfort food can still have perks.

Chuck roast offers protein, iron, zinc, and B vitamins that support muscle health and energy. The pepperoncini and their brine bring a burst of flavor without piling on calories, which helps you rely on less added salt. There’s richness here, thanks to butter and beef, but you can tweak it to suit your needs.

Using less butter, trimming visible fat, or pairing the roast with a heap of roasted vegetables helps balance the plate while keeping the flavor you love.

Pitfalls to Watch Out For

Over-salting: Ranch and au jus mixes are salty. Avoid adding salt until after cooking and tasting. Use low-sodium broth if you’re sensitive to salt.
Dry meat: Chuck roast needs time to break down.If it’s tough, it’s not done. Keep cooking until it shreds easily.
Too much heat: Pepperoncini are usually mild, but brine can build intensity. Start with a small splash and add more at the end if needed.
Skipping the liquid: While some recipes omit broth, a little helps prevent scorching, especially in the oven or Instant Pot.
Greasy leftovers: Chill and skim solidified fat before reheating if you prefer a lighter dish.

Recipe Variations

Lighter Butter: Use 2–4 tablespoons of butter instead of a full stick.You’ll still get richness without going overboard.
Homemade Seasonings: Replace packets with 1 tablespoon dried ranch-style blend (buttermilk powder, garlic, onion, dill, parsley) and 1 tablespoon beef bouillon or homemade gravy seasoning.
Veggie Boost: Add sliced onions, mushrooms, carrots, and small potatoes around the roast for a complete one-pot meal.
Spice It Up: Add a few sliced jalapeños or a pinch of red pepper flakes for extra heat.
Herby Twist: Toss in fresh thyme or rosemary during the last hour for a subtle aromatic layer.
Sandwich Style: Pile the shredded beef on hoagie rolls with provolone, then broil until melty. Serve with juices for dipping.
Gluten-Free: Choose gluten-free ranch and gravy mixes or make your own seasoning blends.

FAQ

Can I use a different cut of beef?

Yes. Chuck roast is best for tenderness and flavor, but brisket or bottom round can work.

They may need a bit more time to soften.

Do I have to use butter?

No, but it’s part of the signature richness. You can reduce the butter or swap part of it with olive oil for a lighter touch.

What if I don’t have pepperoncini?

Use banana peppers or mild pickled jalapeños. If you have neither, add 1–2 tablespoons apple cider vinegar and a pinch of sugar to mimic the tang.

Can I make this ahead?

Absolutely.

It reheats well, and the flavors deepen overnight. Shred, store with the juices, and reheat gently before serving.

Why not sear the meat first?

You can sear for deeper flavor, but the classic recipe skips it and still tastes great. If you have time, a quick sear won’t hurt.

How do I thicken the juices?

Stir 1 tablespoon cornstarch into 1 tablespoon cold water, then whisk into the hot juices and simmer a few minutes.

Or reduce on the stove to concentrate.

Is it spicy?

Not usually. Pepperoncini are mild. The heat level stays low unless you add hot peppers or extra brine.

Can I make it with chicken or pork?

Yes.

Boneless skinless chicken thighs or a pork shoulder work well. Adjust cook time: chicken cooks faster, pork shoulder is similar to beef.

What should I serve with it?

Mashed potatoes, rice, buttered egg noodles, or creamy polenta are classic. Add green beans, roasted broccoli, or a crisp salad on the side.

How do I avoid it being too salty?

Use low-sodium broth, start with half the seasoning packets if you’re cautious, and add more to taste at the end.

The brine also adds salt, so go light initially.
