What Ingredients You Will Need

This Instant Pot Mississippi Roast uses simple, wholesome ingredients to deliver bold flavor and a satisfying texture without any fuss. Most are pantry staples, and a few fresh items make all the difference.

• Chuck roast (3-4 pounds / 1.4-1.8 kg): The star of the show, ideally well-marbled for juicy tenderness.
• Ranch seasoning mix (1 packet or about 1 ounce / 28 grams): Adds that classic tang and herb-packed flavor.
• Au jus gravy mix (1 packet or about 0.87 ounces / 25 grams): For a rich, beefy base that complements the roast beautifully.
• Unsalted butter (1/2 cup / 113 grams): Helps create a luscious sauce and keeps the meat moist.
• Pepperoncini peppers (8-10 peppers) and 1/4 cup (60 ml) of the juice: Brings a mild heat and tang that’s signature to Mississippi Roast. Look for good-quality jars with firm peppers.
• Beef broth (1 cup / 240 ml): The liquid to build steam and cook the roast perfectly in the Instant Pot. Homemade or store-bought both work.
• Fresh cracked black pepper and salt: To taste; I tend to keep it light since the seasoning mixes are already salty.

Optional but recommended:

• Garlic powder (1 teaspoon / 5 grams): For an extra punch of flavor.
• Fresh parsley (for garnish): Adds a pop of color and freshness when serving.

If you want to switch things up, you can swap out the au jus mix for mushroom gravy mix or use dairy-free butter alternatives if needed. For a low-sodium version, pick reduced-salt seasoning packets and adjust salt accordingly.

Equipment Needed

• Instant Pot or Electric Pressure Cooker: The main tool here. I’ve tried this recipe in a 6-quart and 8-quart model, and both work perfectly. If you don’t have one, a slow cooker can be used but expect longer cooking times.
• Tongs: Handy for flipping the roast and moving the meat without tearing it.
• Measuring cups and spoons: For accuracy, especially with seasoning mixes.
• Cutting board and sharp knife: To trim any excess fat or slice the roast before serving.
• Serving platter or dish: To rest the roast before carving and to catch those delicious juices.

For budget-friendly options, many brands offer affordable Instant Pots that work just as well. If your model lacks a sauté function, no worries—just brown the meat in a skillet before adding it to the pot for extra flavor.

Preparation Method

1. Prep the Roast: Pat your 3-4 pound (1.4-1.8 kg) chuck roast dry with paper towels. This helps in browning. Season lightly with salt and freshly cracked black pepper on all sides. (About 5 minutes)
2. Sear the Meat (Optional but recommended): Set your Instant Pot to sauté mode. Melt 1-2 tablespoons of butter or oil and brown the roast on all sides until a deep caramelized crust forms—about 3-4 minutes per side. This step adds depth but you can skip if you’re short on time. (10 minutes)
3. Add Seasonings: Sprinkle the ranch seasoning mix and au jus gravy mix evenly over the roast. Don’t be shy—these packs are the heart of the flavor here. Then, place 1/2 cup (113 g) of unsalted butter on top of the roast, followed by 8-10 pepperoncini peppers scattered around it. Pour 1 cup (240 ml) of beef broth and 1/4 cup (60 ml) of pepperoncini juice into the pot. (5 minutes)
4. Pressure Cook: Seal the lid, set the valve to sealing, and choose the “Manual” or “Pressure Cook” function on high for 60 minutes. The Instant Pot will take about 10-15 minutes to come to pressure before timing starts. (75 minutes total)
5. Natural Release: When cooking ends, let the pot release pressure naturally for 15 minutes (this keeps the meat juicy). Afterward, carefully switch the valve to venting to release any remaining pressure. (15-20 minutes)
6. Rest and Shred: Remove the roast to a serving platter and let it rest for 10 minutes. Using two forks, shred the meat—it should fall apart effortlessly. Stir the cooking juices and pepperoncini into the meat for maximum flavor. (10-15 minutes)
7. Serve: Garnish with fresh parsley if desired and serve with mashed potatoes, roasted veggies, or crusty bread to soak up the sauce. (Immediate)

Pro tip: If the sauce seems thin, switch back to sauté mode and simmer for a few minutes to reduce and thicken. You’ll know it’s ready when it coats the back of a spoon.

Cooking Tips & Techniques

Here’s the real deal on making your Instant Pot Mississippi Roast turn out perfect every time.

• Don’t skip searing: It’s tempting to throw the meat straight in, but browning seals in flavor and adds richness to the sauce. If you’re crunched for time, at least try to brown one side.
• Use fresh pepperoncini juice: The juice brings acidity that tenderizes the roast and adds that signature tang. Don’t substitute with vinegar or lemon juice—it won’t be the same.
• Natural pressure release matters: Quick releasing can toughen the meat or cause it to dry out. Waiting 15 minutes lets the juices redistribute for juicy results.
• Shred while warm: The meat is easier to pull apart when it’s hot. If it’s cooled, just pop it back in the pot with some juices to warm up before shredding.
• Season to taste after cooking: Depending on your seasoning mixes, you may want to add a pinch more salt or pepper once shredded.
• Multitask with sides: While the roast cooks, use your stovetop or oven to prep simple sides like mashed potatoes or steamed greens. This keeps dinner rolling smoothly.

One time I forgot to add the au jus mix (oops!), and the roast was fine but definitely lacked that savory punch. Lesson learned—don’t skimp on the seasoning packs!

Variations & Adaptations

This recipe is flexible and easy to customize depending on your needs or taste buds.

• Slow Cooker Version: Follow the same prep but cook on low for 8 hours or high for 4-5 hours. The meat will be just as tender but takes longer.
• Low-Sodium Option: Use reduced-salt ranch and gravy packets and substitute salt-free beef broth. Add herbs like thyme or rosemary to boost flavor naturally.
• Spicy Twist: Add a diced jalapeño or a splash of hot sauce to the cooking liquid for a subtle kick that wakes up the palate.
• Allergy-Friendly: Swap out butter for coconut oil or vegan butter if dairy is an issue. Make sure to pick ranch seasoning without dairy or gluten if needed.
• Personal Favorite: I once added sliced mushrooms and pearl onions to the pot for extra earthiness and texture—totally optional but highly recommended if you like veggies mingling with your meat.

Serving & Storage Suggestions

This Instant Pot Mississippi Roast is best served warm, straight from the pot, with plenty of the rich juices spooned over the top. It pairs beautifully with creamy mashed potatoes, buttered noodles, or roasted veggies like carrots and green beans.

If you’re serving guests, try plating on a large wooden board or rustic platter for that cozy, homey feel. Sprinkle fresh parsley or thyme for a burst of color and freshness.

To store leftovers, place the shredded roast and juices in an airtight container. Refrigerate for up to 4 days or freeze for up to 3 months. When reheating, warm gently on the stovetop or in the microwave with a splash of broth to keep it moist.

Flavor actually deepens after resting in the fridge overnight—so if you can wait, the next day’s meal tastes even better. Just reheat slowly, and you’ll have juicy perfection once again.

FAQs

Can I use a different cut of beef for Mississippi Roast?

Chuck roast is best for tenderness and flavor, but you can try a brisket or rump roast. Just adjust cooking time accordingly—tougher cuts may need a bit longer.

What if I don’t have pepperoncini peppers?

Pepperoncini are key for the tang and mild heat, but you can substitute with banana peppers or mild pickled peppers. Avoid using hot peppers unless you want a spicier roast.

How do I thicken the sauce if it’s too thin?

Switch the Instant Pot to sauté mode and let the sauce simmer uncovered for 5-10 minutes until it reduces and thickens. You can also mix a teaspoon of cornstarch with cold water and stir it in, cooking until thickened.

Can this recipe be made ahead of time?

Yes! You can cook the roast a day ahead and refrigerate. Reheat gently before serving. The flavors actually improve overnight.

Is Instant Pot Mississippi Roast gluten-free?
