Incredibly tender and full of flavor, Mississippi French Dip Sandwiches are a perfect easy weeknight dinner made in the slow cooker. These sandwiches combine a Mississippi pot roast with a classic french dip sandwich for the perfect bite!
Heat oil in a large skillet on high heat. Season roast on both sides with salt and pepper and sear 2-3 minutes per side. (Seasoning and searing first is optional.)
To a 6 quart or larger Crockpot, stir together French onion soup, 1/2 cup of the pepperoncini pepper juice (discard the rest), the pepperocini peppers, au jus packet and ranch seasoning. Transfer the roast to the Crockpot. Swirl 1/4 cup water in the skillet and pour into the Crockpot. Place butter and mushrooms on top.
Cover and cook on low for 7-8 hours. Once complete, remove the roast, shred, and return to the Crockpot.
Butter and broil or toast hoagie buns with cheese. Add some of the drained beef and veggies to each bun. Serve with Crockpot juices for dipping.
