mississippi pot roast instant pot has saved me from so many chaotic weeknights. You toss in a few pantry staples, press a button, and your kitchen starts smelling like Sunday dinner. The meat turns tender, the gravy gets rich, and everyone suddenly wanders into the kitchen asking when it’s ready. If you’re juggling work, homework, pets, and life, this is the kind of meal that lets you breathe. I’ll walk you through every step, plus my hard-earned tricks so your roast comes out juicy and full of flavor every single time. 
Cooking a pot roast in your electric pressure cooker is a great time saver!
There’s no reason a pot roast should eat up your whole day. With an electric pressure cooker, you can get fork-tender beef in about 90 minutes total, start to finish. The magic here is consistent high pressure that breaks down tough connective tissue and turns a budget-friendly cut into a cozy, savory dinner. You’ll still get that satisfying richness you expect from a slow-cooked roast, just in a fraction of the time.
Here’s the rhythm that works for me: I season the roast generously, sear it for a few minutes per side to build flavor, then layer in the classic Mississippi combo of **ranch seasoning**, **au jus gravy mix**, **pepperoncini**, and a little **butter**. Add **beef broth** to help the cooker build pressure and create a silky, spoon-coating sauce. Lock the lid, set **High Pressure**, and let it do its thing. After cooking, do a **natural release** for 15 to 20 minutes. That pause is the difference between stringy and luscious.
“I used this method on a busy Tuesday, and my family literally scraped the pot clean. I’m not the best cook, but this turned out perfect, super tender, and the sauce was addictive.”
This mississippi pot roast instant pot method is also forgiving. Didn’t sear? Still great. Forgot onions? You’ll be fine. Just keep liquids and seasonings in balance, and let the pressure cooker work hard while you relax for a bit.
Can I use a frozen roast?
Short answer: yes, you can. If your chuck roast is frozen, skip the sear and place it right in the pot. Add your ranch, au jus, pepperoncini, butter, and at least 1 cup of broth or water so the cooker can reach pressure. A trivet is helpful, but not required. The key is extra time.
For a 3-pound frozen roast, I set the cooker to High Pressure for 90 to 100 minutes. For a 4-pounder, bump it to about 110 minutes. Then do a natural release for 15 to 20 minutes before opening the lid. If the roast doesn’t shred easily, seal it back up and cook another 10 minutes. You’re aiming for super tender, which often happens around 200 to 210 degrees F internal for a fall-apart roast.
One more tip: if your cooker throws a burn warning, you likely need more liquid or better deglazing. Add a splash of broth, scrape the bottom well, and try again.

Tips for making the best Instapot Mississippi Pot Roast
Ingredients that never let me down
- 3 to 4 lb **chuck roast** – marbled is best for tender results
- 1 packet **ranch seasoning**
- 1 packet **au jus** gravy mix
- 6 to 10 **pepperoncini** peppers + 2 to 3 tablespoons of the juice
- 4 to 6 tablespoons **unsalted butter**
- 1 cup **beef broth** – low sodium if possible
- 1 medium onion, sliced (optional)
- 2 cloves garlic, smashed (optional)
- 1 tablespoon oil for searing
Step-by-step directions that truly work
- Pat the roast dry and season with salt and pepper. Hit Sauté and add oil. Sear 3 to 4 minutes per side to build a flavorful crust. Remove temporarily.
- Add onions and garlic to the pot and sauté 1 minute. Pour in a splash of broth and **deglaze** the bottom, scraping up every browned bit. Those bits are flavor gold.
- Return the roast to the pot. Sprinkle ranch and au jus over the top. Dot with butter. Add pepperoncini and their juice. Pour in the remaining broth around the sides.
- Seal the lid. Cook on High Pressure for 60 to 70 minutes for a 3-pound roast or 75 to 85 minutes for a 4-pound roast. Let pressure release naturally for 15 to 20 minutes.
- Open the lid, shred the meat with two forks, and fold it back into the sauce. Taste and adjust seasoning. If you’d like thicker gravy, stir in a cornstarch slurry and simmer on Sauté for a couple of minutes.
- For less salt, use **low sodium broth**, unsalted butter, and just half the au jus packet. It’s still delicious, just gentler.
For the best mississippi pot roast instant pot, I always give it that natural release time and never rush the shred. The sauce should be glossy and a little tangy from the pepperoncini.

Trust me, the flavors play nicely together on a weekly meal plan.
How to Serve Mississippi Roast
When your mississippi pot roast instant pot is done, serving it is the fun part. This beef loves a cozy carb and a crunchy veggie. Go classic with mashed potatoes, or do something different like loading it onto fluffy rolls for sliders. The bright, briny pepperoncini in the gravy cuts through the richness, so your plate never feels heavy.
- Over creamy mashed potatoes or buttered egg noodles
- On toasted hoagie rolls with provolone for drippy sandwiches
- On steamed rice with roasted green beans or broccoli
- Piled into soft tacos with shredded cabbage and a squeeze of lime
- Over a baked potato with cheddar and chives

How to Store Leftovers
Leftovers are a gift. Let the roast cool, then store it in an airtight container with its gravy in the fridge for up to 4 days. The sauce keeps it juicy. Reheat gently on the stove over low heat or in the microwave, adding a splash of broth if needed. If you notice a fat cap solidify on top after chilling, lift it off before reheating for a cleaner taste.
Freezing works well too. Pack portions with some of the sauce in freezer bags or containers and freeze for up to 3 months. Thaw overnight in the fridge and reheat slowly. I love repurposing leftovers into quesadillas, shepherd’s pie filling, or a topper for baked potatoes. That way, your one pot of beef turns into several totally different meals.
Common Questions
What cut of beef works best?
Chuck roast is the best pick. It’s marbled just enough to turn tender and shreddy under pressure.
How do I prevent it from being too salty?
Use **low sodium broth**, unsalted butter, and start with half the au jus packet. You can always add more at the end.
Do I need to sear the roast?
No, but searing adds deeper flavor. If you skip it, make sure you still deglaze after sautéing the onions and garlic.
Can I add potatoes and carrots to the pot?
Yes, but add them after the meat cooks. Open the lid, add chunky pieces, and pressure cook 3 to 4 minutes, then quick release. They’ll stay tender, not mushy.
What if I see a burn warning?
Cancel, add a splash of broth, and scrape the bottom well. Restart once the pot is clean and liquid covers the base.
