INGREDIENTS

Here is everything you need to make this slow cooker Mississippi pot roast with potatoes and carrots.
For The Roast
- 2 to 3 lb boneless chuck roast
- 1 tablespoon olive oil
- 1 packet ranch dressing mix
- 1 package au jus gravy mix
For The Sauce And Toppings
- ½ cup pepperoncini liquid
- ½ cup beef broth
- ¼ cup butter, cut into pats
- 8 whole pepperoncini peppers
Vegetables
- 2 cups baby carrots
- 4 medium Yukon gold or red potatoes, quartered
PREPARATION
This recipe comes together in layers, which helps everything cook evenly and soak up flavor.
Step 1: Sear The Roast
Heat the olive oil in a large skillet over medium-high heat. Sear the chuck roast for 2 to 3 minutes per side until browned. This step adds extra flavor, but it can be skipped if needed.
Step 2: Build The Slow Cooker
Transfer the roast to the bottom of the crock pot. Scrape up the browned bits from the skillet and add them to the slow cooker.
Sprinkle the ranch dressing mix and au jus gravy mix over the roast. Pour in the beef broth and pepperoncini liquid.
Step 3: Add Vegetables And Butter
Add the carrots, potatoes, and whole pepperoncini peppers around the roast. Lay the butter pats evenly over the top.
Step 4: Slow Cook
Cover and cook on low for 8 hours. The roast should be very tender and easy to shred when done.
Shred the beef directly in the pot or remove it and shred in a bowl, adding cooking liquid back to taste.
CONSEILS AND SUGGESTIONS
- Keep the lid on the slow cooker to lock in moisture.
- If you are short on time, skip the searing step. The roast will still turn out delicious.
- For a low-carb option, leave out the potatoes and carrots and serve over cauliflower mash or cauliflower rice.
NOTES AND VARIATIONS

Shredded leftovers are excellent for wraps, casseroles, or stuffed peppers. This Mississippi pot roast with potatoes and carrots reheats well and tastes even better the next day.
FAQs
Yes. Searing adds flavor, but the recipe still works without it.
Yukon gold or red potatoes hold their shape and cook evenly.
It is flavorful but not spicy. The pepperoncinis add tang, not heat.
