The chuck roast is non-negotiable here—look for well-marbled cuts at Costco or Whole Foods for optimal tenderness. Boneless saves prep time but bone-in adds depth. The seasoning packets might seem shortcut-y, but McCormick’s Au Jus and Hidden Valley Ranch are the gold standard for authenticity. Avoid low-fat butter substitutes; the full-fat version creates the richest gravy (worth the calories).

No ranch packet? Mix 1 tbsp dried dill, 1 tsp onion powder, 1 tsp garlic powder, and ½ tsp parsley. Out of au jus? Beef bouillon plus cornstarch works in a pinch. Pepperoncini can be swapped for banana peppers (slightly milder). The Worcestershire adds complexity—Annie’s or Lea & Perrins are reliable brands.

Store uncooked roast in its original packaging for 3-5 days in the fridge. Once cooked, the pot roast keeps beautifully for 4-5 days refrigerated or freezes for 3 months. Reheat gently to preserve that melt-in-your-mouth texture (microwave tends to dry it out).

Step-by-Step Instructions for Pressure-Cooked Mississippi Pot Roast

This method guarantees fall-apart tenderness with minimal effort and maximum flavor.

Step 1: Sear and Season the Chuck Roast

Pat the 3 lb chuck roast dry with paper towels, then season generously with the 1 tsp kosher salt and 0.5 tsp black pepper. This step ensures a deep, flavorful crust during searing. Set your Instant Pot to the “Sauté” function on high heat.

Add a splash of oil to the pot and sear the chuck roast on all sides until deeply browned, about 4-5 minutes per side. This caramelizes the surface, adding complexity to the final dish. Remove the roast and set it aside.

Step 2: Build the Flavor Base

In the same pot, add the 1 whole yellow onion (cut into chunks) and the 4 cloves garlic cloves (minced). Sauté for 2-3 minutes until the onion softens and the garlic becomes fragrant. This creates a robust foundation for the sauce.

Stir in the 1 package au jus gravy mix, 1 package ranch seasoning mix, 1 tbsp Dijon mustard, and 1 tsp dried thyme. Cook for 1 minute, stirring constantly, to toast the spices and deepen their flavors. The mixture will thicken slightly.

Step 3: Deglaze and Pressure Cook

Pour in the 0.5 cup beef broth and 2 tbsp Worcestershire sauce, scraping the bottom of the pot to release any browned bits. This deglazing step prevents burning and incorporates rich, concentrated flavors into the sauce.

Place the seared chuck roast back into the pot. Add the 8 pieces pepperoncini peppers and the 0.5 cup unsalted butter (cut into pats) on top. Secure the lid, set the valve to “Sealing,” and cook on high pressure for 60 minutes.

Step 4: Natural Release and Shred

Allow the pressure to release naturally for 15 minutes, then carefully switch the valve to “Venting” to release any remaining pressure. This gradual release prevents the roast from drying out and ensures it remains tender.

Open the lid and use two forks to shred the chuck roast directly in the pot. The meat should pull apart effortlessly, with a rich, velvety sauce surrounding it. Stir everything together to coat the roast evenly in the flavorful liquid.

Let it sit for 5-10 minutes to allow the flavors to meld before serving. The sauce will thicken slightly as it cools, creating the perfect consistency to cling to every bite.

Pro Tips For Making Mississippi Pot Roast Recipe Instapot

  • Sear the Chuck: Take 5 minutes to brown the chuck roast on all sides before pressure cooking—it locks in flavor and prevents a bland, gray finish. I skipped this once and regretted it.
  • Use Full Fat Butter: Skip the substitutions; unsalted butter is non-negotiable here for richness, and it balances the tang from the pepperoncinis. Margarine just doesn’t cut it.
  • Don’t Drain the Juice: After cooking, resist the urge to discard the liquid—it’s packed with flavor from the au jus and ranch mixes. I use it to make a quick gravy with a cornstarch slurry.
  • Add Peppers Last: Stir in the pepperoncini peppers and their juice after the roast is done, not before. This keeps their zesty kick from mellowing out during pressure cooking.

Wine and Beer Pairings for These Flavors

Bold Red Wines

A rich Cabernet Sauvignon from Napa Valley complements the beef’s depth with its dark fruit and structured tannins. The boldness stands up to the pepperoncini tang beautifully. I love Caymus for this pairing. 🍷

Medium-Bodied Reds

A Merlot with its softer tannins and plum notes enhances the dish without overpowering it. Try Chateau Ste. Michelle from Washington state for a budget-friendly option that always delivers.

Craft Beer Options

A malty amber ale like Fat Tire from New Belgium balances the richness with its caramel notes. The slight sweetness contrasts the savory ranch and au jus flavors perfectly.

Lighter Beer Pairings

For a crisper choice, a pilsner such as Stella Artois cuts through the richness while cleansing your palate. The effervescence helps reset your taste buds between bites. 🍺

White Wine Alternative

Surprisingly, a bold Chardonnay with its buttery notes mirrors the dish’s richness. I recommend Kendall-Jackson Vintner’s Reserve for its creamy texture that stands up to the beef.

Non-Alcoholic Option

A sparkling black cherry soda like Boyert’s offers the same effervescence as beer with sweet-tart notes that complement the pepperoncini perfectly. Serve well-chilled for best results.

Frequently Asked Questions

1

Can I use a different cut of beef?

Stick with chuck roast for best results. Brisket works but needs 90 minutes under pressure. Avoid lean cuts like sirloin—they dry out.

2

What if I don’t have ranch seasoning?

Mix 1 tbsp dried dill, 1 tsp onion powder, and 1 tsp garlic powder. This DIY version mimics the packet perfectly.

3

Can I cook this on low pressure?

No—high pressure is essential for breaking down the connective tissue. Cooking on low would require 2+ hours and still might not get tender.

4

How do I thicken the sauce?

Remove the meat, then set Instant Pot to “Sauté.” Simmer the sauce for 5-10 minutes until reduced. A cornstarch slurry works too.
