Step-by-Step Mississippi Pot Roast Instructions

Step 1 – Prep & Sear the Roast

Allow your 3–4 lb chuck roast to rest at room temperature for about 20 minutes. Season generously with salt, pepper, garlic powder, and onion powder.

Heat a drizzle of avocado oil in a Dutch oven or large skillet over high heat. Sear the roast for 2–4 minutes per side until a deep brown crust forms.

This locks in flavor and helps create a beautiful gravy later. Remove the roast and set it aside.

💡 Pro Tip: You can add extra veggies like carrots or potatoes if you want a heartier roast, but traditionally, this dish keeps it simple with just onions, garlic, and pepperoncini.

Step 2 – Choose Your Cooking Method

Oven Method (Classic & Tender)

Return the seared roast to the Dutch oven. Sprinkle in ranch seasoning and au jus mix.

• Add 4–8 pepperoncini peppers and 2 tbsp of their brine for tang.
• Toss in 1 sprig of rosemary and pour in ½ quart beef stock.
• Add ½ stick to 1 stick of butter on top.

Cover and bake at 350°F for 3–4 hours, until fork-tender.

Shred the roast and stir to combine everything into a rich, buttery gravy.

Slow Cooker Method (Set It & Forget It)

Place the seared roast in your slow cooker.

Add ranch mix, au jus mix, butter, onions, garlic, peppers, and beef stock.

Cover and cook on LOW for 8 hours or HIGH for 4–5 hours, until tender.

Strain the juice from the pot and whisk in 1 tbsp flour + 2 tbsp water, and stir in near the end for a thicker gravy.

Shred and mix into the juices before serving.

Pressure Cooker / Instant Pot Method (Fast & Flavorful)

On the Sauté setting, sear the roast on all sides.

Add butter, flour, garlic, onions, ranch mix, au jus, stock, and peppers.

Seal and cook on High Pressure for 60 minutes.

Let pressure release naturally for 15 minutes, then quickly release any remaining steam.

Strain the juice from the pot, whisk 1 tbsp flour + 2 tbsp water, and stir in near the end for a thicker gravy.

Shred the roast and mix into the flavorful gravy — ready in under 90 minutes total!
