(Slow Cooker Tender Beef with Pepperoncini & Rich Gravy)
Mississippi Pot Roast is one of those easy comfort-food dinners that practically cooks itself! A beef chuck roast is slow-cooked with ranch seasoning, au jus gravy mix, butter, and pepperoncini until it’s incredibly tender and falling apart. The cooking juices turn into a rich, savory gravy that’s perfect over mashed potatoes. ❤️
Full Recipe (Ingredients + Instructions)
Ingredients 🥩
- 3½–4 lb beef chuck roast
- 1 tablespoon olive oil, optional for searing
- Salt and freshly ground black pepper, lightly
- 1 packet ranch seasoning mix
- 1 packet au jus gravy mix
- 6–8 whole pepperoncini peppers
- ¼ cup pepperoncini juice
- ½ cup unsalted butter
- ½ cup beef broth, optional
- 4 garlic cloves, minced, optional
Optional Vegetables 🥔🥕
- 1½ lbs baby potatoes or chopped Yukon Gold potatoes
- 4 large carrots, cut into chunks
- 1 medium onion, quartered
Step 1: Season the Roast 🥩
Pat the chuck roast dry with paper towels.
Season lightly with black pepper and just a little salt.
Go easy on the salt! Ranch seasoning and au jus mix already contain plenty of seasoning.
Step 2: Sear the Beef 🔥
Heat olive oil in a large skillet over medium-high heat.
Sear the roast for approximately 3–4 minutes per side until it develops a beautiful dark brown crust.
This step is optional, but it adds much deeper beef flavor.
Transfer the roast to your slow cooker.
Step 3: Add the Seasonings 🌿
Sprinkle the entire packet of ranch seasoning over the roast.
Sprinkle the au jus gravy mix over that.
Add minced garlic if using.
There’s no need to stir everything together.
Step 4: Add the Pepperoncini 🌶️
Arrange 6–8 pepperoncini peppers around and on top of the roast.
Pour in approximately ¼ cup pepperoncini juice.
That tangy pepperoncini brine is one of the ingredients that gives Mississippi Pot Roast its signature flavor.
For extra tang, add a little more.
Step 5: Add the Butter 🧈
Place the butter directly on top of the roast.
If you want additional gravy, pour about ½ cup beef broth around the roast, not directly over the seasonings.
Don’t Add Too Much Liquid!
Chuck roast releases plenty of its own juices while slow cooking.
You don’t need to completely cover the meat.
Step 6: Cook Low & Slow ⏰
Cover and cook:
LOW
8–9 hours
HIGH
5–6 hours
LOW is my preferred method for the most tender result.
The roast is ready when it easily pulls apart with a fork.
Step 7: Shred the Beef 😍
Transfer the roast to a cutting board or shred it directly in the slow cooker.
Remove any large pieces of excess fat.
Use two forks to pull the beef into large, juicy pieces.
Return everything to those delicious cooking juices.
Step 8: Make That Gravy! 🥣
For a thicker gravy, remove approximately 2 cups cooking liquid and transfer it to a saucepan.
Mix:
- 2 tablespoons cornstarch
- 2 tablespoons cold water
Whisk the slurry into the simmering cooking liquid.
Cook for 2–3 minutes until thickened.
Pour the gravy back over the shredded beef.
Now we’re talking! 🥩😍
