Get ready to be blown away by this juicy and flavorful Mississippi Pot Roast, a recipe that owes its impressive flavors to ranch and pepperoncini, made incredibly easy thanks to the Instant Pot!
Instant Pot Mississippi Pot Roast
Pot roast – a tried and true favorite comfort food across households. This dish is beloved for its simple preparation and ability to provide a heartwarming, hearty meal for a large crowd. Perfect for family gatherings, a pot roast is often left to cook while you can focus on other tasks.
However, if you think pot roast cannot get any easier or tastier, I challenge you to try this Mississippi Pot Roast.
What is Mississippi Pot Roast?
You might be familiar with a traditional pot roast, but the Mississippi version is an entirely different experience. Usually, it includes a chuck roast that is slow-cooked with four distinctive ingredients – ranch, Au Jus, peperoncini, and butter. These ingredients might not immediately make you think “Mississippi,” but they come together to form a truly unique dish.
The Instant Pot Advantage
The traditional method of cooking a pot roast can be quite time-consuming. A large chuck roast could take up to six hours to achieve that melt-in-your-mouth tenderness, making it a recipe usually reserved for leisurely Sundays. After all, who has the luxury to spend half a day on a weekday preparing dinner?
This is why we have the Instant Pot. This recipe will take about 1 to 1.5 hours in the Instant Pot, which might seem long, but it’s a significant time-saver compared to the more common 6 hours. This also makes it feasible for a weekday dinner.
Key Ingredients For Pot Roast
As we’ve discussed, the ranch and pepperoncini make this pot roast unique which pack a flavor punch you’ll love.
- chuck roast
- low sodium beef broth
- pepperoncini juice
- dry Ranch seasoning mix packet
- Au Jus gravy mix packet
Cooking Mississippi Pot Roast In The Instant Pot
- Heat vegetable oil in your Instant Pot using the SAUTE mode.
- Slice the chuck roast into 3 or 4 pieces and brown them in the pot for 10 minutes, adding more oil if needed.
- Remove the meat and deglaze the pot with beef broth, then stir in pepperoncini juice. Return the meat to the pot, season with ranch and gravy mix, add pepperoncinis and butter, and turn off SAUTE mode.
- Seal the pot, and set it to MANUAL mode at HIGH PRESSURE for 60 minutes. Then, let it release pressure naturally for 15 minutes.
- Vent to release any remaining pressure; remove the pot roast from the Instant Pot and serve it with its juices.
- For thicker gravy, stir in a slurry of 2 tablespoons of cornstarch and ¼ cup cold water, cooking for 2 minutes on SAUTE mode. Thin with additional liquid if needed.
Tips & Variations
Mississippi Pot Roast is already next-level and simple, but these tips will really keep it that way.
- Choose a high-quality chuck roast for the best results. The marbling of fat in this cut ensures a juicy, tender pot roast.
- Be careful not to overcook your meat. This will ensure it’s juicy and tender, not dried out.
- Opt for a packet of Au Jus gravy. This is NOT the same as brown gravy. The texture and consistency will be different.
- Thickening the Juices: If you prefer gravy, use the cornstarch and water mixture described in the recipe card below. Remember to whisk it well to avoid lumps.
- Check for Doneness: The roast should be tender enough to pull apart with a fork easily. If it’s not, seal the pot back up and cook for an additional 10 to 20 minutes.
- You can serve your roast with the pepperoncini on the side but don’t shred them into the roast.
Can I Use A Frozen Roast
- Absolutely, a frozen roast can be used, although it may require extra cooking time to ensure the meat is completely cooked and tender enough to pull apart.
- I serve my Mississippi pot roast over mashed potatoes. Spoon that sauce right over everything and call it a day.
- If you don’t love mashed potatoes, you can serve it the same way over mashed cauliflower, rice, or riced cauliflower.
- I also love my Mississippi pot roast served with a side of roasted potatoes and/or roasted carrots.
Ideas for Using Leftovers
- Leftovers taste even better the next day. Try transforming them into a French Dip Sandwich, a hearty soup with root vegetables, or use the shredded beef in tacos or burritos.
How to Store Leftovers
- Leftovers can be stored in the fridge for 3 to 5 days or frozen for up to 4 months. If freezing, include the juices to keep the meat moist.
