What Ingredients You Will Need

This Instant Pot Mississippi Pot Roast recipe uses straightforward, wholesome ingredients to deliver bold flavor and tender texture—without any fuss. Most of what you need is probably in your pantry already, and there’s plenty of room for substitutions if you’re missing something. Here’s what to gather:

• For the Pot Roast:
  • Chuck roast (3-4 lbs / 1.4-1.8 kg): Boneless is best; look for good marbling for extra tenderness.
  • Beef broth (1 cup / 240 ml): Adds richness and depth to the gravy. I like to use low-sodium for better control.
  • Ranch seasoning mix (1 packet or 1 oz / 28 g): The classic flavor base—Hidden Valley or your favorite store brand works great.
  • Au jus gravy mix (1 packet or 1 oz / 28 g): For extra savory notes. If you can’t find this, use brown gravy mix as a substitute.
  • Pepperoncini peppers (8-10 whole, plus 1/2 cup juice / 120 ml): Adds tang without too much heat. Substitute banana peppers if needed.
  • Unsalted butter (4 tbsp / 56 g): Cut into pieces; creates a luscious, velvety gravy. Use plant-based butter for a dairy-free version.
  • Garlic cloves (3, minced): For a punch of flavor (optional, but recommended).
  • Salt & black pepper: To taste. Start light since mixes may contain salt.
• For the Gravy (optional):
  • Cornstarch (2 tbsp / 16 g): Mixed with 2 tbsp water for thickening, if desired.

Ingredient Tips & Substitutions:

• Chuck roast is classic, but brisket or round roast will work. Just adjust cooking time for leaner cuts.
• For gluten-free, use a certified gluten-free ranch and gravy mix, and thicken gravy with arrowroot starch.
• Don’t have pepperoncini? Swap in mild banana peppers, or add a splash of apple cider vinegar for tang.
• Prefer a spicier kick? Toss in a few jalapeño slices.
• Butter can be subbed with olive oil for a lighter version, though the flavor will change slightly.

I personally love using Better Than Bouillon for the beef broth base, and I always reach for a good quality butter (Kerrygold, anyone?) for that extra richness. Trust me, picking the right cut of beef and not skimping on the peppers makes a huge difference. In summer, I sometimes swap the jarred pepperoncini for fresh garden banana peppers—the tang is unbeatable. If you’re in a pinch, you can use pre-minced garlic, but fresh is definitely worth the extra minute.

Equipment Needed

You don’t need a kitchen full of gadgets for this Instant Pot Mississippi Pot Roast recipe—just a few trusty tools and your favorite pressure cooker. Here’s my go-to lineup:

• Instant Pot or electric pressure cooker (6 or 8 quart): Essential for fast, tender results. I’ve used both brands and found the 8-quart is great for big gatherings.
• Tongs: For turning and removing the roast. Silicone-tipped ones won’t scratch your pot.
• Cutting board and sharp knife: To trim and slice the roast (trust me, a sharp knife is a lifesaver).
• Measuring cups and spoons: For broth, seasonings, and cornstarch slurry.
• Small bowl: Mixing up your gravy thickener, if needed.
• Whisk: To blend gravy smooth—though a fork works in a pinch.
• Serving platter or bowl: For presenting that beautiful, saucy roast.

If you don’t have an Instant Pot, a stovetop pressure cooker will work—just keep an eye on timing. For budget-friendly tools, I swear by IKEA’s basic tongs and mixing bowls. My favorite maintenance tip: always clean the Instant Pot sealing ring well after cooking anything with garlic or peppers (trust me, those flavors linger!). And if you’re just starting out, you don’t need fancy gadgets—just solid basics and a little bit of kitchen grit.

Preparation Method

Here’s how to make the most tender Instant Pot Mississippi Pot Roast with savory gravy. Follow these steps for foolproof results every time:

1. Trim and season the roast: Pat the chuck roast dry with paper towels. Sprinkle both sides generously with salt and black pepper. (This helps build a flavorful crust!)
2. Sauté the beef (8 minutes): Set your Instant Pot to “Sauté” mode and add 2 tablespoons butter. Once melted and shimmering, sear the roast for about 3-4 minutes per side until deep golden brown. Don’t rush—this step adds tons of flavor! Remove beef and set aside.
3. Deglaze the pot (2 minutes): Pour in 1 cup (240 ml) beef broth and use a wooden spoon to scrape up all those brown bits stuck to the bottom. This prevents the dreaded “burn” notice and gives your gravy depth.
4. Add seasoning and peppers (2 minutes): Sprinkle ranch mix and au jus mix evenly over the beef. Return the roast to the pot. Scatter minced garlic, pepperoncini peppers, and pour in 1/2 cup (120 ml) pepperoncini juice. Dot the top with remaining butter pieces.
5. Pressure cook (65 minutes): Lock the lid and set to “Manual” or “Pressure Cook” on high for 65 minutes (for a 3-4 lb / 1.4-1.8 kg roast). If using a smaller roast, reduce time by 10 minutes. Let pressure release naturally for 15-20 minutes—don’t quick release, or the beef may toughen.
6. Shred and thicken gravy (10 minutes): Open lid, transfer roast to a cutting board. Shred with two forks (it should fall apart easily). For gravy, set Instant Pot to “Sauté” again. In a small bowl, mix 2 tbsp (16 g) cornstarch with 2 tbsp water. Stir into pot juices and whisk until thickened (about 2-3 minutes). Add shredded beef back into the pot and coat in gravy.
7. Taste and adjust: Taste for seasoning—add more salt, pepper, or pepperoncini juice if you want extra tang. If gravy is too thick, add a splash of broth. Too thin? Add a little more cornstarch slurry.
8. Serve: Pile beef and gravy onto a serving platter or bowl. Garnish with extra peppers if you like, and spoon over mashed potatoes, rice, or sandwich rolls.

Preparation Notes: If your roast looks a little tough after pressure cooking, let it sit in the hot gravy for 10 more minutes. It will soften up! If you get a “burn” notice during sauté, add a splash of broth and scrape the bottom well. Sensory cues: You’ll know the roast is done when it’s fork-tender and falls apart easily. The gravy should smell rich and tangy, with a silky texture. For efficiency, prep your peppers and mix seasonings while the beef is browning—saves time and keeps things moving.

Cooking Tips & Techniques

Over time, I’ve learned that a few little tweaks make this Instant Pot Mississippi Pot Roast recipe truly shine. Here’s what works best for me:

• Don’t skip the sear: Browning the beef adds a layer of flavor that really sets this dish apart. I tried skipping it once—never again! The depth just wasn’t there.
• Layer your seasoning: Sprinkle the ranch and au jus mixes evenly, not in clumps, to avoid salty pockets.
• Pressure release matters: Natural release is key for tender beef. Quick release can make the meat chewy. Patience pays off here!
• Multitasking tip: While the roast cooks, prep your sides (mashed potatoes, rice, or rolls). The timing lines up perfectly.
• Consistency secrets: If your gravy is thin, don’t panic—just simmer with cornstarch. If too thick, whisk in a bit more broth.
• Watch for salt: Some ranch and gravy mixes pack in sodium. Taste before adding extra salt.
• Personal lessons learned: Once, I forgot to deglaze—ended up with a “burn” notice and had to start over. Always scrape up those flavor bits! And if you want a spicier roast, add a few extra peppers, but don’t go overboard (learned that the hard way).

For consistent results, always use a roast with decent marbling. Lean cuts can dry out, especially under pressure. I also found that letting the shredded beef soak in the gravy for a few extra minutes before serving makes it even more flavorful. And hey, if you’re short on time, you can skip thickening the gravy—just spoon the juices right over your meal. It’s still delicious!

Variations & Adaptations

One of the best things about this Instant Pot Mississippi Pot Roast recipe is how easy it is to tweak for different diets, seasons, or flavor cravings. Here are some favorite ways to switch things up:

• Low-Carb & Keto: Use a sugar-free ranch mix and skip the cornstarch (or swap for xanthan gum). Serve over cauliflower mash for a low-carb dinner.
• Gluten-Free: Choose certified gluten-free ranch and gravy mixes, and thicken with arrowroot starch. Double-check your beef broth label, too!
• Seasonal Twist: In summer, swap jarred pepperoncini for fresh garden peppers. In winter, add a handful of diced carrots and potatoes before pressure cooking for a stew-like feel.
• Flavor Boost: Add a splash of Worcestershire sauce to the broth or a teaspoon of smoked paprika to the seasoning mix for extra depth.
• Cooking Method Swap: No Instant Pot? Make it in a slow cooker on low for 8 hours—same ingredients, just more time.
• Personal favorite: I’ve tried adding sliced mushrooms in the last 10 minutes of sauté—brings an earthy note that pairs perfectly with the savory gravy.

Allergen substitutions are easy, too—swap butter for olive oil or plant-based margarine, and use dairy-free ranch if needed. If you want a milder version, cut back on the peppers or skip the juice. Prefer more tang? Add a splash of vinegar at the end. And for those with picky eaters, you can shred the beef extra fine and tuck it into sandwiches or wraps. Honestly, there’s no wrong way to enjoy this pot roast!

Serving & Storage Suggestions

For the perfect Instant Pot Mississippi Pot Roast experience, serve it piping hot—straight from the pot onto a platter, with the savory gravy ladled all over. I love pairing it with creamy mashed potatoes, fluffy rice, or crusty rolls. Add a side of roasted veggies or a crisp green salad to balance the richness.

This roast makes an amazing sandwich filling, too—pile it high on toasted buns with a little extra gravy and maybe a slice of sharp cheddar. For beverages, a cold glass of sweet tea or a hearty red wine works well (whatever suits your mood, really).

Storing leftovers is a breeze: transfer beef and gravy to an airtight container and refrigerate for up to 4 days. It freezes beautifully, too—just portion into freezer bags, label, and stash for up to 3 months. For reheating, warm gently on the stovetop or microwave, adding a splash of broth if needed to loosen the gravy. Honestly, the flavors seem to deepen after a day or two in the fridge, making next-day sandwiches or tacos even tastier.
