Introduction

Mississippi Pot Roast is a flavorful, tender beef dish that slowly simmers to perfection with just a few simple ingredients. Its tangy pepperoncini peppers and rich ranch seasoning create a mouthwatering combination that’s perfect for a comforting family meal.

The dish shows a black round plate with two main layers. On the bottom right, there is a light and fluffy layer of creamy mashed potatoes, off-white in color with a smooth texture and slight pepper specks. On the left and center sits a hearty layer of tender, shredded brown meat with a shiny, moist appearance, mixed with chunks of cooked orange carrots, light green celery pieces, and small caramelized onion bits. There is a glossy brown gravy drizzled over both the meat and mashed potatoes. A pale green pepper with a smooth surface lies on the edge of the plate. A black fork rests on the mashed potatoes side. The plate rests on a white marbled texture surface. photo taken with an iphone --ar 4:5 --v 7

Ingredients

4 pound Chuck roast
1 Onion, diced
1 packet Ranch dressing mix
1 packet Au jus gravy mix
8 Pepperoncini peppers
1/4 cup Pepperoncini juice
1/4 cup Butter, sliced

Instructions

Step 1: Season the chuck roast all over with salt and pepper.
Step 2: Optional: Heat 1 to 2 tablespoons of cooking oil in a large skillet over high heat until very hot and just starting to smoke. Sear the roast on all sides, about 2 to 3 minutes per side, until browned.
Step 3: For slow cooker: Place the roast in the slow cooker. Add diced onion, ranch dressing mix, au jus gravy mix, pepperoncini peppers, pepperoncini juice, and sliced butter. Cover and cook on low for 8 hours.
Step 4: For Instant Pot: Combine all ingredients in the Instant Pot. Add 1 cup beef broth. Cook on manual high pressure for 1 hour. Allow the pressure to release naturally for 10 to 15 minutes.
Step 5: To serve, shred the meat with forks or tongs. Serve over egg noodles, mashed potatoes, or rice. Enjoy!

Tips & Variations

For extra flavor, add garlic powder or fresh garlic when seasoning the roast.
Substitute pepperoncini with banana peppers if you prefer milder heat.
Using the slow cooker method enhances tenderness and develops deeper flavors, especially when cooking low and slow.

Storage

Store leftover Mississippi Pot Roast in an airtight container in the refrigerator for up to 4 days. Reheat gently in the microwave or on the stovetop to avoid drying out the meat. You can also freeze cooked roast for up to 3 months; thaw in the refrigerator overnight before reheating.

How to Serve

FAQs

Can I use a different cut of beef?

Chuck roast is ideal for this recipe due to its marbling and tenderness when slow-cooked, but you can also use a brisket or beef shoulder with similar results.

Do I need to sear the roast before cooking?

Searing is optional but recommended because it adds extra flavor and a beautiful crust to the roast. If short on time, you can skip this step and still have a delicious meal.
