Ingredient Notes

Best cut of beef

Chuck roast is the best choice here. It has enough marbling and connective tissue to become tender and juicy in the Instant Pot. Leaner cuts can turn dry or chewy.

Pepperoncini flavor

These peppers are not meant to make the dish very spicy. They mostly add a gentle tangy flavor that balances the richness of the beef and butter.

Seasoning packets

If you are sensitive to sodium, use lower-salt options where possible. You can also reduce the packet amounts slightly, but do not reduce too much or the roast may taste flat.

Ingredient Prep Table

Prep TaskWhat to DoWhy It Helps
Pat roast dryUse paper towels before seasoningHelps the meat sear better
Trim only large hard fatLeave most marbling in placeKeeps roast flavorful
Bring roast out brieflyLet sit 20 to 30 minutesHelps more even cooking
Measure liquid firstHave broth and pepper juice readyMakes the searing stage smoother
Mix cornstarch laterOnly after pressure cookingPrevents lumps and over-thickening

Step-by-Step Method

1. Prepare the roast

Pat the chuck roast dry with paper towels. If there is a very thick outer layer of hard fat, trim a little, but do not remove too much. Season lightly with black pepper and garlic powder if using.

2. Sear the beef

Turn the Instant Pot to Sauté mode. Add the olive oil and let it heat until shimmering. Place the roast in the pot and sear for about 3 to 4 minutes per side until browned. This step is worth doing because it adds flavor to the final dish.

Remove the roast and set it aside.

3. Deglaze the pot

Pour in the beef broth and use a wooden spoon to scrape up any browned bits from the bottom. This is very important because stuck bits can trigger a burn warning.

4. Build the flavor

Return the roast to the pot. Sprinkle the ranch seasoning and au jus mix over the top. Add the butter, pepperoncini peppers, and pepperoncini juice.

Do not stir too much at this stage. Let the seasonings sit mostly on top of the meat.

5. Pressure cook

Seal the lid and set the valve to Sealing. Cook on High Pressure for:

  • 60 minutes for a 3-pound roast
  • 70 minutes for a 4-pound roast

After cooking, allow a 15 to 20 minute natural release, then carefully do a quick release for any remaining pressure.

6. Shred or slice

Open the lid and check the roast. It should be very tender and easy to pull apart with forks. If it still feels too firm, cook for another 10 to 15 minutes on High Pressure.

Shred the roast directly in the pot or remove it to a platter first.

7. Thicken the sauce if desired

For a thicker gravy, turn on Sauté mode. Mix cornstarch and water in a small bowl, then stir it into the cooking liquid. Simmer for a few minutes until thickened.

Tips for the Best Result

A recipe like this is simple, but a few small habits make it much better.

  • Use chuck roast, not a lean cut
  • Sear the meat well for better flavor
  • Always deglaze the pot after browning
  • Give the roast enough time to become fork-tender
  • Let it rest in the juices before serving
  • Taste the sauce first before adding extra salt

How to make it even better? A nice upgrade is adding a few cloves of fresh garlic or a small onion during cooking. That said, the classic version is intentionally simple, so keep extras light.

Common Mistakes to Avoid:

This section matters because pot roast can go wrong in ways that are easy to prevent.

Skipping the sear

You can technically skip it, but the final flavor will be flatter. Browning creates a deeper, richer base.

Not scraping the bottom of the pot

After searing, browned bits can stick and cause the Instant Pot to show a burn notice. Deglazing with broth solves this.

Using too little liquid

The Instant Pot needs enough liquid to build pressure properly. Do not reduce the broth too much.

Choosing the wrong cut

A lean roast may cook through, but it usually will not become tender and luscious in the same way. Chuck roast is the safer choice.

Releasing pressure too fast

A full quick release right away can make the meat tense and slightly less tender. A short natural release gives better texture.

Undercooking the roast

If the roast is tough, it likely needs more time, not less. Tough meat in pressure cooking often means the connective tissue has not fully broken down yet.

Storage and Reheating

  • Refrigeration: Store leftovers in an airtight container with some of the cooking liquid for up to 4 days.
  • Freezing: Freeze for up to 3 months. Let it cool first, then pack in portions with extra sauce to help prevent dryness.
  • Reheating: Warm gently on the stove or in the microwave with a spoonful of broth or sauce. This helps keep the beef moist.

Frequently Asked Questions

Can I use a frozen roast in the Instant Pot?

Yes, but it is not ideal if you want to sear first. A frozen roast usually needs more time, often 20 to 30 minutes extra depending on size. For best flavor and texture, thawing first is better.

Is Mississippi pot roast spicy?

Not usually. Pepperoncini peppers bring tang more than heat. The dish is flavorful and bold, but generally mild.

Can I make this recipe without ranch seasoning?

Yes. You can make a homemade blend with dried parsley, dill, onion powder, garlic powder, salt, and pepper. The flavor will be slightly different, but still good.

Why is my roast still tough after pressure cooking?

It likely needs more time. Tough roast often means the connective tissue has not broken down fully yet. Add another 10 to 15 minutes of pressure cooking.

Can I add vegetables to the pot?

You can, but delicate vegetables may become too soft during the long cook time. It is often better to cook carrots or potatoes separately, or add large chunks later if your model and timing allow.

What is the best way to serve leftovers?

Leftover shredded roast is excellent over mashed potatoes, tucked into sandwiches, spooned over rice, or even folded into sliders.
