How to Make Mississippi Pot Roast Sandwich

1. Season with salt and pepper and sear roast(s) 2-3 minutes per side in oil in a large skillet on high heat.

2. To a Crockpot, stir together French onion soup, ½ cup of the pepperoncini pepper juice (discard the rest), pepperocini peppers, au jus packet, and ranch packet.

3. Transfer the roast to the Crockpot. Swirl ¼ cup water in the skillet and pour into the Crockpot. Place butter and mushrooms on top. 

4. Cover and cook on low for 7-8 hours. Once complete, remove the roast, shred, and return to the Crockpot. 

5. Butter or brush with oil and broil or toast hoagie buns. Add cheese slices and add a serving of drained meat/veggies to each bun. Serve sandwiches with Crockpot juices on the side for dipping.

Making Mississippi Pot Roast in the Instant Pot

Great news! Yes, this Mississippi pot roast can be made in the Instant Pot. If you prefer to cut down on the cook time by using a pressure cooker rather than a slow cooker follow my instructions below.

• Yes! Turn on the Instant Pot and select the “Sauté” function. Once hot, add oil and sear the beef roast on all sides until browned. Remove the roast.
• Add butter and stir until melted. Stir in the French onion soup, ranch dressing mix, au jus packet, pepperoncini peppers, pepperoncini juice, and water. Return the beef and add the mushrooms on top.
• Close the lid and select the "Meat/Stew" function. Set the timer for 60-90 minutes, depending on the size of your roast and how tender you want it to be.
• Once the cooking time is complete, let the Instant Pot naturally release pressure for 10-15 minutes, then quick release any remaining pressure.
• Open the lid and carefully remove the beef roast from the Instant Pot.
• Shred the beef roast with a fork and return it to the Instant Pot, stirring to combine it with the sauce.
  

Making Mississippi Pot Roast in the Oven

If you'd rather go the traditional route, make this Mississippi French dip in the oven by roasting the meat instead.

After searing in an oven safe pan on the stove top, place the roast in a roasting pan or baking dish.

In a separate bowl, stir together the French onion soup, pepperoncini juice and peppers, au jus packet, ranch, mushrooms, water and butter. Pour the mixture over the roast and cover with a tight-fitting lid.

Place in a preheated 275°F oven for 3.5 to 4 hours, flipping the roast halfway through cooking. The beef should easily shred with a fork when done. Remove from the oven, shred the beef and discard any residual fat.

Tips and Substitutions

• Mississippi French Dip sandwiches can be made with any cheese of choice.
• These sandwiches are excellent served with a side salad, french fries, tater tots, roasted vegetables or raw veggies and dip.
• The sodium content can be adjusted to your preference. To lower the content, you can omit salting the beef before searing. You can also make the french onion soup, au jus packet, and ranch seasoning from scratch. 
• You can use ranch seasoning from a ready-made seasoning packet or 2 tablespoons from Homemade Ranch Seasoning.
• A homemade au jus packet can be made by combining 2 tablespoons regular or low-sodium beef bouillon granules or beef base, 1 tablespoon cornstarch, ½ teaspoon onion powder, ½ teaspoon garlic powder, ½ teaspoon dried thyme and ¼ teaspoon black pepper.

Storage and Freezing

Once the meat has cooled to room temperature, you can store it in an airtight container in the refrigerator for up to four days. If you want to store it for longer, you can freeze it for up to three months.
