If you love set-it-and-forget-it meals that taste like you spent all day in the kitchen, this one’s for you. Mississippi pot roast is famous for its rich, savory flavor with a slightly tangy kick. The slow cooker does all the heavy lifting, turning a tough cut of beef into fork-tender shreds.

Why This Recipe Works

This recipe uses a handful of pantry staples to create deep, layered flavor without extra steps. The combination of ranch seasoning, au jus gravy mix, butter, and pepperoncini peppers makes the beef savory, tangy, and rich.

Low-and-slow cooking breaks down a chuck roast, turning it juicy and tender. You don’t need to brown the meat, and you don’t need extra liquid—just let the crockpot do its job.

Shopping List

• Beef chuck roast (3–4 pounds), boneless
• Ranch seasoning mix (1 packet, about 1 ounce)
• Au jus gravy mix (1 packet, about 1 ounce)
• Unsalted butter (1/2 cup or 1 stick)
• Pepperoncini peppers (6–10 whole peppers)
• Pepperoncini brine (1/4 cup from the jar)
• Optional: Yellow onion (1, sliced)
• Optional: Garlic cloves (2–3, smashed)
• Optional: Carrots or baby potatoes (for a built-in side)
• Optional: Black pepper (to taste)

How to Make It

1. Prep the crockpot. Lightly grease the insert or use a liner for easy cleanup.
2. Layer the aromatics. If using onion and garlic, spread them on the bottom of the crockpot. They add sweetness and aroma.
3. Add the roast. Place the chuck roast in the crockpot.

   No need to sear—though you can sear for 2–3 minutes per side in a hot pan if you want extra flavor.

4. Season generously. Sprinkle the ranch seasoning and au jus packets evenly over the roast.
5. Add butter and peppers. Place the stick of butter on top of the roast. Scatter the pepperoncini peppers around the meat and pour in 1/4 cup of their brine.
6. Optional veggies. Tuck carrots and/or baby potatoes around the roast if you want an all-in-one meal.
7. Cook low and slow. Cover and cook on Low for 8–10 hours or on High for 4–5 hours, until the beef shreds easily with a fork.
8. Shred and mix. Remove large fat pieces. Shred the meat in the crockpot and stir it into the juices so every bite is saucy.
9. Taste and adjust. Add black pepper if needed.

   The mixes provide salt, so you usually won’t need extra.

10. Serve. Spoon over mashed potatoes, buttered noodles, rice, or cauliflower mash. Garnish with extra pepperoncini slices if you like more tang.

How to Store

• Refrigerator: Store in an airtight container with its cooking juices for up to 4 days. The liquid keeps the meat moist.
• Freezer: Cool completely, then freeze in freezer-safe bags or containers for up to 3 months.

  Include some juices to prevent dryness.

• Reheating: Warm gently on the stove over low heat or in the microwave with a splash of broth or water. Stir occasionally until heated through.
• Make-ahead tip: Combine the roast, seasonings, butter, and peppers in a gallon bag (minus the brine) and refrigerate overnight. Dump into the crockpot and add brine in the morning.

Health Benefits

• Protein-rich: Chuck roast is high in protein, which supports muscle repair and helps keep you full.
• Collagen and iron: Slow-cooked beef contains connective tissues that break down into gelatin, and beef supplies iron and B vitamins.
• Customizable sodium: Using reduced-sodium ranch or homemade seasoning can lower salt content without losing flavor.
• Balanced plate potential: Pair with vegetables like carrots, green beans, or a salad to round out the meal with fiber and micronutrients.

Pitfalls to Watch Out For

• Using the wrong cut: Lean cuts like sirloin tip can turn dry.

  Chuck roast has enough marbling to stay tender.

• Not cooking long enough: If it doesn’t shred easily, it needs more time. Toughness usually means undercooked, not overcooked.
• Too salty: Packets can be salty. Choose low-sodium mixes, use unsalted butter, and avoid adding extra salt until the end.
• Watery sauce: If the juices seem thin, remove the lid for the last 20–30 minutes on High or stir in a cornstarch slurry (1 tablespoon cornstarch + 1 tablespoon water).
• Skipping the brine: The pepperoncini liquid adds tang and balance.

  Without it, the roast can taste flat.

Recipe Variations

• Mushroom upgrade: Add sliced cremini mushrooms in the last 2 hours for an earthy twist.
• Onion soup swap: Replace the au jus packet with a dry onion soup mix for a deeper, onion-forward flavor.
• Homemade seasoning: Use 2 teaspoons garlic powder, 1 teaspoon onion powder, 1 teaspoon dried dill, 1 teaspoon dried parsley, 1 teaspoon dried chives, 1/2 teaspoon black pepper, and 1/2 teaspoon kosher salt instead of ranch.
• Spicy kick: Add red pepper flakes or use hot pepperoncini. You can also add a splash of pickled jalapeño brine.
• Gravy-style finish: Strain the cooking liquid, simmer it in a saucepan, and whisk in a cornstarch slurry to make a silky gravy.
• Pressure cooker method: Sear the roast in an Instant Pot, add seasonings and peppers, then pressure cook on High for 60–70 minutes with natural release.
• Lighter butter: Use 2–4 tablespoons butter instead of a full stick. The flavor stays great with less richness.
• Veggie-loaded: Add chunks of parsnips, rutabaga, or sweet potatoes for more variety and nutrients.

FAQ

What cut of beef is best for Mississippi pot roast?

Chuck roast is the top choice because it’s well-marbled and becomes tender over long cooking.

Round roast or brisket can work, but chuck gives the best texture.

Do I need to add broth or water?

No. The roast releases juices as it cooks, and the butter plus pepperoncini brine provide enough liquid for a flavorful sauce.

Can I skip the butter?

Yes, but the butter adds richness and helps emulsify the sauce. If you prefer less fat, use 2–4 tablespoons instead of a full stick.

Is there a substitute for pepperoncini?

Banana peppers are the closest swap.

If you need a non-spicy option, use mild banana peppers and their brine.

How do I keep it from being too salty?

Use unsalted butter, low-sodium seasoning mixes, and taste before adding any extra salt. You can also add a splash of water or low-sodium beef broth at the end to dilute.

Can I make it ahead for a party?

Absolutely. Cook the day before, chill in the fridge, and reheat gently with the juices.

Keep it warm in the crockpot on the Warm setting for serving.

What should I serve with it?

Mashed potatoes are classic. Rice, egg noodles, roasted green beans, or a crunchy salad also pair well with the rich sauce.

Why is my roast tough?

It likely needs more time. Keep cooking until the meat shreds easily with a fork and connective tissues break down.

Can I use frozen beef?

For food safety and even cooking, it’s best to thaw the roast first.

If using an Instant Pot, you can cook from frozen, but add extra time.

How can I make it gluten-free?

Use a gluten-free au jus or a gluten-free beef bouillon powder. Many ranch mixes are naturally gluten-free, but always check labels.
