Recipe Overview
Time: It takes about 10 minutes to throw everything into the crock-pot and 5 hours to cook.
Ingredients: You only need five ingredients - a chuck roast, a jar of pepperoncini, a packet of ranch dressing, a packet of au jus sauce, and butter.
Ease: Incredibly easy! No chopping, searing, or extra steps-just dump everything in and walk away.
With just 5 ingredients and almost no prep, this slow cooker classic delivers incredibly tender, flavorful beef in a rich, tangy sauce. It's the kind of no-fuss comfort food you'll want to make again and again.
Ingredients & Substitutions
Chuck Roast - You'll need a chuck roast around 2½ pounds. If your roast is larger, increase the cook time by about 30-60 minutes for every extra pound to ensure it becomes fall-apart tender.
Pepperoncini - These mild peppers (and their juice) add a tangy, slightly acidic bite that helps cut through the richness of the meat and butter. Use whole or sliced, depending on your preference.
Ranch Dressing Mix- Be sure to use the dry seasoning mix, not bottled ranch dressing. The mix adds savory, herby flavor without making the dish too creamy.
Au Jus Mix- A dry seasoning packet that adds rich, beefy depth to the sauce. You can substitute a brown gravy mix if that's what you have on hand.
Butter- Butter adds richness and helps the seasonings absorb into the meat. Unsalted is best so the dish doesn't become too salty. You can use margarine in a pinch, or reduce the amount slightly if you prefer it lighter.

How to Make Crockpot Mississippi Pot Roast
Step 1 | Add Everything to the Slow Cooker
Place the chuck roast in a 6-quart slow cooker, sprinkle with ranch and au jus mixes, then top with butter, pepperoncini peppers, and their juice.
Step 2 | Cook
Cover and cook on low for 5-6 hours, or until the meat is fall-apart tender.
Step 3 | Skim the Fat & Shred
After cooking, skim off the excess fat for a cleaner sauce, then shred the beef in the slow cooker and stir to combine with the juices.
Step 4 | Serve
Serve hot over mashed potatoes, rice, egg noodles, or pile it onto sandwich rolls for a hearty meal.
Tips & Notes
Skim the fat for better flavor: This roast makes a rich, buttery sauce, but it also leaves a greasy layer on top. Skimming it off with a spoon or a paper towel held by tongs makes the finished dish taste lighter and more balanced.
Watch the cook time: Chuck roast is usually perfectly tender after 5-6 hours on low. Cooking it too long can cause the meat to dry out or become stringy.
