The beauty of this recipe lies in its straightforward, accessible ingredients. Each item serves a distinct role, whether it’s building flavor, tenderizing the meat, or thickening the sauce to silky perfection.

3-5 pounds chuck roast (cubed, 2″ pieces): The star of the dish, chuck roast becomes melt-in-your-mouth tender when cooked right.
2 tablespoons olive oil: For searing the beef to seal in those delicious juices and add a golden crust.

¼ cup pepperoncini juice (from the jar): Adds a zesty, tangy note that brightens the entire dish.
¾ cup beef broth (low or no sodium): Provides the savory base for the cooking liquid and helps keep the meat moist.
1 ounce ranch seasoning (1 packet): Infuses the roast with that classic creamy, herby ranch flavor.

1 ounce onion soup mix (1 packet): A perfect blend of onions and spices rounding out the savory depth.
5-10 pepperoncini (as per your spice preference): For little bursts of spice and acidity that balance the richness.
3 tablespoons butter (unsalted, cut into 4-6 slices): Adds richness and tenderizes the meat during cooking.

2 tablespoons cornstarch: To thicken the sauce into a luscious gravy.
2 tablespoons water: Mixed with cornstarch to create a slurry for thickening.

Directions

Step 1: Start by heating 2 tablespoons of olive oil in your Instant Pot using the sauté setting. Once hot, add the beef cubes in batches, making sure not to crowd the pot. Sear each side until browned and caramelized, about 3-4 minutes per batch. This step is key for flavor, so be patient and don’t rush it. Then, set the beef aside.

Step 2: Pour the pepperoncini juice and beef broth into the pot to de-glaze, scraping up all those delicious browned bits off the bottom with a wooden spoon. This brings in so much extra flavor right from the start.

Step 3: Return the seared beef cubes to the pot. Sprinkle the packet of ranch seasoning and onion soup mix evenly over the top. Add the pepperoncini peppers next. Stir gently to coat the meat with the seasonings and broth, making sure the flavors mingle nicely.

Step 4: Distribute 3 tablespoons of butter sliced into pieces over the meat. This will melt during cooking and add that silky, rich finish that I adore.

Step 5: Secure the lid on your Instant Pot and set the valve from VENT to SEAL. Cook on high pressure for 60 minutes. When the time is up, allow the pressure to release naturally for 15 minutes, then quick release any remaining pressure to avoid overcooking.

Step 6: Carefully transfer the beef to a large bowl and shred it into bite-sized pieces using two forks. Meanwhile, turn the Instant Pot back to the sauté setting and bring the sauce to a gentle bubble.

Step 7: In a small bowl, whisk together the cornstarch and water until smooth. Stir this slurry into the pot and keep stirring until the sauce thickens to a luscious gravy consistency, about 2-3 minutes.

Step 8: Return the shredded beef to the Instant Pot and stir well to coat every piece in that rich sauce. Let it warm through for another minute or two, then you’re ready to serve!

Servings and Timing

This Instant Pot Mississippi Pot Roast Recipe yields about 6 hearty servings, perfect for a family dinner or gathering with friends. Preparing the ingredients and searing the beef takes roughly 15-20 minutes. The main cooking time under pressure is 60 minutes, plus a 15-minute natural release and a few minutes for thickening and shredding. All told, you’re looking at about 1 hour and 40 minutes from start to finish, including resting time for maximum tenderness.

How to Serve This Instant Pot Mississippi Pot Roast Recipe

In the left part of the image, a clear liquid is being poured into the pot, creating bubbles and splashes among the dark brown, almost amber-colored liquid with specks of seasoning floating around. In the right part, a woman's hand is holding a wooden spoon inside the pot, stirring the dark brown liquid that has a few light reflections and a slightly thick texture from the mixed spices.

When it comes to serving this pot roast, I love pairing it with creamy mashed potatoes or buttery egg noodles since they soak up that incredible gravy perfectly. Roasted or steamed green beans, sautéed spinach, or even a simple crunchy salad add a fresh contrast that keeps the meal balanced. I always garnish with a few extra pepperoncini slices or chopped fresh parsley to bring a pop of color and zing to the plate.

For beverages, a robust red wine like a Zinfandel or Malbec complements the rich, savory flavors beautifully. Alternatively, a crisp lager or a classic cocktail such as a whiskey sour works well for casual dinners. For those sticking to non-alcoholic drinks, a sparkling water with a squeeze of lemon or iced tea feels refreshingly light alongside this cozy meal.

I usually serve this roast hot and fresh from the Instant Pot, spooning generous portions onto each plate. The portion size depends on whether it’s a main course or part of a larger spread, but for a full meal, I recommend about 8 ounces of shredded beef per person. It’s a wonderful choice for everything from weeknight dinners to Sunday family feasts or even holiday gatherings where you want a failproof crowd-pleaser.

Variations

I’ve experimented with a bunch of variations on this Instant Pot Mississippi Pot Roast Recipe depending on what’s in my pantry or dietary preferences. For a gluten-free version, just swap out the onion soup mix and ranch seasoning for gluten-free labeled equivalents or make your own blends with dried herbs and gluten-free bouillon. You won’t sacrifice any flavor that way!

If you want to change up the protein, I’ve had good luck using pork shoulder instead of chuck roast, which becomes equally tender and flavorful. For those who want to try a slower cooking method, this recipe also works beautifully in a slow cooker—just sear the meat, then let it cook on low for about 8 hours until falling apart tender.

For a twist on the flavor, try adding a splash of Worcestershire sauce or a tablespoon of smoked paprika to deepen the savory notes. You can also dial up the heat by increasing the number of pepperoncini peppers or adding a pinch of cayenne. Personally, I find even small tweaks make the recipe feel brand new every time I make it.

Storage and Reheating

Storing Leftovers

Leftover Instant Pot Mississippi Pot Roast is a real treat to have on hand. I store it in airtight containers or heavy-duty resealable bags and keep it refrigerated for up to 4 days. The sauce helps keep the shredded meat moist and flavorful, so even next-day leftovers taste fantastic.

Freezing

This pot roast freezes beautifully. After cooling completely, I portion it into freezer-safe containers or bags, removing as much air as possible to prevent freezer burn. It keeps well frozen for up to 3 months. Thaw it overnight in the fridge before reheating, and the quality remains excellent.

Reheating

The best way I’ve found to reheat the roast is gently on the stovetop over low heat. Add a splash of beef broth or water if the sauce has thickened too much, and stir occasionally until warmed evenly. You can also reheat it in the microwave, covering it loosely to retain moisture, but be careful to avoid overheating and drying it out. Reheating slowly preserves that tender texture and keeps the flavors vibrant.

FAQs

Can I use a roast other than chuck for this recipe?

Yes! While chuck roast is ideal for its marbling and tenderness, you can substitute with other cuts like brisket or pork shoulder. Just keep in mind cooking times may vary slightly, but the Instant Pot adapts well to different roasts.

Is it necessary to sear the meat before pressure cooking?

Searing is highly recommended because it locks in the juices and develops those rich, caramelized flavors that make the dish special. Skipping this step may save time but the end result won’t have the same depth.

Can I make this recipe dairy-free?

Absolutely! The main dairy ingredient is butter, which you can swap for a dairy-free alternative like margarine or coconut oil. Just keep the same quantity to maintain richness.

How spicy is this pot roast? Can I adjust the heat?

The heat level mainly comes from the pepperoncini peppers and their juice, which are mildly spicy with some tang. You can control the spice by adjusting the number of peppers and the amount of juice you use to suit your taste.

Can I double this recipe for a larger crowd?

You can double the ingredients, but be mindful of your Instant Pot’s maximum fill line—avoid overfilling. You might need to cook in batches or use a larger model for best results.
