Easy Slow Cooker Mississippi Pot Roast for Family Dinners

Ingredients Needed for Slow Cooker Mississippi Pot Roast
- Chuck roast: Becomes tender and juicy after hours in the slow cooker.
- Ranch dressing mix: Adds tangy, herby flavor that complements the beef.

How to make Slow Cooker Mississippi Pot Roast
**For more detailed instructions, please refer to the printable recipe card below.**

Place the chuck roast in the slow cooker and sprinkle the ranch and au jus mixes evenly over the top.

Add the butter and pepperoncini and pepperoncini juice.

Cover and cook on low for 8 hours or until tender.

Remove the roast from the slow cooker and set it aside on a plate.

Skim any excess fat from the surface of the cooking liquid if needed.

Shred the beef using two forks.

Return it to the slow cooker and stir to coat it in the sauce
Variations
- Mississippi Pot Roast Sandwiches: Shred the beef and pile it high on toasted rolls with melted provolone or mozzarella. It makes an easy dinner or a great way to use up leftovers the next day.
- Spicy version: If you like a little heat, add more pepperoncini or pour in some of the brine from the jar. It adds a nice kick without taking away from that buttery flavor.
- Mississippi Pot Roast with Gravy: Want it a bit thicker? Stir a small cornstarch slurry into the sauce after cooking. It turns into a rich, glossy gravy that’s perfect for spooning over mashed potatoes.
- Oven-baked version: Don’t have a slow cooker? No problem. Layer everything in a Dutch oven, cover tightly, and bake at 300°F for about 3 hours until tender. The flavor comes out just as delicious.
- Mississippi Pot Roast Sliders: This one’s fun for parties. Use the shredded beef on slider buns, top with cheese, and bake until everything’s warm and melty. They disappear fast at get-togethers.
Serving Suggestions
- Garlic Mashed Potatoes: This pot roast and creamy mashed potatoes are made for each other. My Garlic Mashed Potatoes soak up every bit of that flavorful sauce and make the meal feel complete.
- Rustic Bread: A thick slice of Rustic Bread on the side is perfect for mopping up all those buttery juices. I always end up grabbing an extra piece.
- Honey Glazed Carrots: Sweet, buttery Honey Glazed Carrots balance out the richness of the roast beautifully and add a nice pop of color to the plate.
- Cheesy Bacon Green Beans: My Cheesy Bacon Green Beans are a family favorite with this recipe. The smoky bacon and gooey cheese go perfectly with the tender beef.
- Over baked potatoes: This is one of my favorite ways to serve it. Load up fluffy Air Fryer Baked Potatoes with a generous scoop of the pot roast and drizzle a bit of the sauce on top. It’s hearty, filling, and perfect for family dinners. You could even take a note from my Sloppy Joe Baked Potatoes and add a little shredded cheese or sour cream for a fun twist.

Storage and Freezing
- How should I store Slow Cooker Mississippi Pot Roast?
Keep leftovers in an airtight container in the fridge for up to 4 days. The flavors deepen as it sits.
- Can I freeze Slow Cooker Mississippi Pot Roast?
Yes. Cool completely, then freeze in containers or bags for up to 3 months. Thaw overnight and reheat slowly on the stove or in the slow cooker.

Tips & Tricks
- Pick the right roast: Chuck roast is the way to go here. It has just enough marbling to stay juicy and tender after hours in the slow cooker. Leaner cuts like round roast tend to dry out.
- Be patient with the lid: I know it’s tempting to peek, but every time you lift the lid, you lose heat and slow down the cooking. Let it work its magic undisturbed until it’s time to shred.
- Go easy on salt: The seasoning mixes already bring plenty of flavor, so there’s no need to add more salt until you taste it at the end.
- Add veggies for a full meal: Toss in chunks of carrots, onions, or baby potatoes if you want a one-pot dinner. They’ll soak up that delicious sauce while the roast cooks.
- Plan for leftovers: The flavor gets even better after a night in the fridge. Use the extra beef in sandwiches, wraps, or even loaded Baked Potatoes for an easy second meal.
