Crock Pot Mississippi Roast
Few things rival the comfort of coming home to a simmering Crock Pot filled with something rich, savory, and soul-soothing. Especially when autumn chills the air, this Mississippi Roast becomes my culinary refuge. It’s more than just a meal—it’s a memory in the making, a centerpiece at family tables, echoing with laughter, clinking cutlery, and stories passed around like warm bread.
This roast isn’t your average slow-cooked fare. It’s melt-in-your-mouth beef layered with bold, briny pepperoncini and enveloped in a velvety fusion of zesty seasoning mixes. It’s the dish I turn to for Sunday suppers, holiday gatherings, and nights when only comfort food will do.

Key Ingredients and Flavors
At the heart of this dish is a beautifully marbled chuck roast. Add a handful of tangy pepperoncini, a packet each of ranch dressing and au jus mix, and let slow time work its magic. The result? A luscious roast with richness, tang, and an umami depth that satisfies like no other.
Selecting the Best Ingredients
- Chuck Roast: Seek out a well-marbled cut—those veins of fat promise tenderness and deep flavor. Grass-fed beef adds extra character.
- Pepperoncini Peppers: Bright, firm, and blemish-free peppers give the dish its signature zing.
- Ranch Dressing Mix: Choose clean-label options—organic or preservative-free—for a healthier take.
- Au Jus Gravy Mix: Again, purity matters. Aim for mixes with real ingredients and no artificial fillers.
- Beef Broth: Opt for low-sodium to better manage seasoning and avoid overpowering the roast.

Ingredients
- 3–4 lbs chuck roast
- 1 packet ranch dressing mix
- 1 packet au jus gravy mix
- 12–15 pepperoncini peppers + a splash of their brine
- 1 cup low-sodium beef broth
- 1 tbsp olive oil (for searing)
- Optional: fresh thyme or parsley for garnish
Instructions
1. Preparing the Roast
Let the roast sit out for 30 minutes to come to room temp—this encourages even cooking. Season both sides generously with salt and pepper.
2. Searing the Roast
Heat olive oil in a skillet over medium-high heat. Sear the roast 4–5 minutes per side until a golden crust forms. This step, while optional, creates a robust flavor foundation.
3. Assembling in the Crock Pot
Place the seared roast into your Crock Pot. Scatter pepperoncini over and around it. Sprinkle the ranch and au jus mixes on top. Pour in the broth and pepperoncini juice, allowing the flavors to mingle.
4. Cooking the Roast
Cover and cook on low for 8 hours or high for 4. The meat should fall apart effortlessly with a fork—tenderness is your cue that it’s ready.
