What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples or easy to find at any grocery store, so you won’t have to go on a wild ingredient hunt.

• Beef Chuck Roast (about 3-4 lbs / 1.4-1.8 kg) – the star of the show; look for a marbled cut for juiciness.
• Ranch Dressing Mix (1 packet or about 1 oz / 28 g) – adds that creamy, herby flavor that’s crucial here.
• Au Jus Gravy Mix (1 packet or about 1 oz / 28 g) – gives a rich, savory background to the beef.
• Unsalted Butter (4 tbsp / 60 g) – places on top of the roast for richness and moisture.
• Pepperoncini Peppers (about 6-8 peppers plus 2 tbsp juice) – these tangy little peppers bring a subtle kick and acidity that balances the richness.
• Carrots (4-5 medium, peeled and cut into chunks) – tender and sweet, they soak up all the flavors.
• Baby Potatoes (1.5 lbs / 680 g, halved if large) – creamy and perfect for soaking in the juices.
• Yellow Onion (1 large, sliced) – adds a soft, sweet depth to the dish.
• Garlic Cloves (3-4, minced) – because garlic just makes everything better.
• Salt and Freshly Ground Black Pepper – to taste; enhances all the flavors naturally.

Pro tip: I like to use a trusted brand like Hidden Valley for the ranch mix and Lipton for the au jus because they consistently give the best flavor and texture. If you want to switch things up, you can use dried herbs instead of ranch mix, but it won’t quite have the same nostalgic punch. Also, feel free to swap baby potatoes for Yukon gold or red potatoes, depending on what you have on hand.

Equipment Needed

• Slow Cooker (Crock-Pot): A 6-quart (5.7-liter) slow cooker is ideal for this recipe to comfortably fit the roast and vegetables.
• Sharp Knife: For slicing vegetables and trimming the roast if needed. A good, sturdy chef’s knife works best.
• Cutting Board: Preferably wood or plastic for easy cleanup.
• Measuring Spoons: To measure seasoning packets and butter precisely.
• Tongs or Forks: For handling the roast when placing it in and out of the slow cooker.
• Optional: A skillet for searing the roast before slow cooking if you want extra flavor (though not necessary).

Honestly, you don’t need anything fancy here. If you don’t have a slow cooker, you can use a heavy Dutch oven and cook low and slow in the oven for a few hours instead. For those on a budget, basic slow cookers from brands like Crock-Pot or Hamilton Beach work wonders and last for years if you take care of them by cleaning promptly after use.

Preparation Method

1. Prep the Vegetables (10 minutes): Peel and chop the carrots into large chunks, halve the baby potatoes if they’re big, slice the onion, and mince the garlic. Set aside.
2. Season the Roast (5 minutes): Pat your beef chuck roast dry with paper towels to help it brown better if you choose to sear later. Generously season it on all sides with salt and pepper.
3. Layer the Slow Cooker (5 minutes): Spread the sliced onions, carrots, potatoes, and minced garlic evenly on the bottom of the slow cooker. This not only flavors the veggies but also creates a natural “rack” for the roast.
4. Add the Roast and Seasonings (2 minutes): Place the seasoned roast on top of the vegetables. Sprinkle the ranch dressing mix and au jus gravy mix evenly over the roast. Dot the butter slices on top, then scatter the pepperoncini peppers around and drizzle 2 tablespoons of their juice over everything.
5. Cook Low and Slow (8-9 hours): Cover with the lid and cook on low for 8-9 hours or on high for 4-5 hours. The low setting is best for that tender, fall-apart texture you’re aiming for.
6. Check for Doneness and Serve (5 minutes): The roast should be fork-tender and easy to pull apart. Vegetables will be soft but not mushy. Use two forks to shred the beef right in the slow cooker or transfer to a platter and slice. Spoon the juices and veggies over the top.
7. Troubleshooting Tip: If your roast isn’t tender enough, cook an extra hour on low. If the veggies are too soft, add them halfway through cooking next time.

When I made this for the first time, I skipped searing and it still turned out amazing, but if you want a little extra depth, a quick 3-minute sear per side in a hot skillet adds a nice crust. Just remember, the slow cooker does most of the work, so don’t stress about it.

Cooking Tips & Techniques

Getting this Mississippi Pot Roast just right is mostly about patience and layering flavors. Here are some tricks I’ve learned from several attempts (and a few small disasters!):

• Don’t Skip the Butter: It melts slowly and bastes the meat, keeping it moist and flavorful throughout the long cook time.
• Use Low Heat When Possible: Cooking low and slow is key for that tender texture. High heat risks drying the roast out.
• Distribute Seasonings Evenly: Sprinkle the ranch and au jus mixes on top of the roast, but also around the veggies to spread flavor.
• Don’t Peek Too Often: Every time you lift the lid, heat escapes and cooks slower. Trust the slow cooker and resist the urge to check every hour.
• Vegetable Timing: If you prefer your veggies firmer, add them halfway through cooking. I personally like them soft, soaking in all those delicious juices.
• Leftovers Are Magic: This roast tastes even better the next day once the flavors have had time to meld fully.

One time, I rushed and cooked it on high for just 4 hours, but the roast was a little tough. Lesson learned! Slow and steady wins the race here. Also, a splash of pepperoncini juice really brightens the dish, so don’t be shy with it.

Variations & Adaptations

This slow cooker Mississippi Pot Roast recipe is super flexible, which is one reason I love it so much. Here are a few ways you can make it your own:

• Low-Carb Version: Skip the potatoes and swap carrots for cauliflower florets or parsnips for a keto-friendly twist.
• Spicy Kick: Add a few slices of jalapeño or a dash of cayenne pepper to the pepperoncini peppers for some heat.
• Vegetarian Adaptation: Use large portobello mushrooms or a hearty seitan roast with vegetable broth and similar seasonings for a plant-based version.
• Different Vegetables: Try adding celery, parsnips, or turnips for a seasonal spin.
• Oven Method: If you don’t have a slow cooker, place everything in a Dutch oven, cover tightly, and bake at 300°F (150°C) for 3-4 hours.

Personally, I once swapped in sweet potatoes instead of baby potatoes, and the slight sweetness was a lovely contrast to the tangy peppers. Feel free to experiment and find what suits your taste buds best!

Serving & Storage Suggestions

This Mississippi Pot Roast is best served hot, straight from the slow cooker, with the tender vegetables and plenty of that flavorful jus spooned over the top. I like to serve it with a crusty bread to soak up those delicious juices or alongside a simple green salad to balance the richness.

Leftovers store beautifully in an airtight container in the refrigerator for up to 4 days. The flavors intensify overnight, so if you can wait, you’re in for a treat! To reheat, warm gently in the microwave or on the stovetop with a splash of beef broth to keep things juicy.

If you want to freeze leftovers, portion them out and freeze for up to 3 months. Thaw overnight in the fridge before reheating. Just a heads up: vegetables may get a bit softer after freezing, but the roast stays tender and tasty.

Can I use a different cut of beef?

Yes! While chuck roast is ideal for tenderness and marbling, you can use brisket or rump roast, but cooking times may vary slightly.

Not necessarily. Searing adds flavor and color but the slow cooker will still produce a tender and tasty roast without it.

What if I don’t have pepperoncini peppers?

You can substitute with banana peppers or mild pickled peppers, but the tangy flavor of pepperoncini is pretty unique and worth trying to find.

Can I prepare this recipe in the morning and let it cook all day?

Absolutely! Just set your slow cooker to low and let it work its magic while you go about your day.

How do I thicken the sauce if it’s too thin?

Remove the roast and veggies, then mix 1 tablespoon cornstarch with 2 tablespoons cold water and stir into the juices. Cook on high for 15 minutes to thicken.
