This Pressure Cooker Peperoncini Pot Roast is easily the best roast I've ever had. Hands-down. It's incredibly flavorful and has a little extra kick that just puts it over the top!
I'm gonna be honest. My Mama made a delicious roast when we were growing up, but as an adult, I've always had hit or miss results with my roasts. Sometimes they were great. Other times they were bland and boring.
That is... until I made this Peperoncini Pot Roast.
A few months back, my sister Amanda and sister-in-law Amy started gushing about this new roast recipe they were making in their slow cookers. When they named off the ingredients, I knew I had to try it!
Then, as if it were meant to be, along came this opportunity to work with Mezzetta. Since their peperoncinis were the only ones I'd been using in this roast recipe - it seemed only fitting that I share this Pressure Cooker Peperoncini Pot Roast recipe on the blog.
Not long after I started making it, I saw a recipe shared on Facebook that was almost identical to the one my SIL had given me and that's when I realized that this viral recipe was also known as "Mississippi Pot Roast". What?! I'm a Mississippi girl. It was definitely meant to be!! Haha!
The biggest difference in how Amy makes this roast, and how most of the recipes I've seen are made, is that she also tosses in a pile of sliced mushrooms. My husband (and lots of other family members) love mushrooms so this is a perfect addition for us.
And because I can't ever follow any recipe exactly as it's written, I also made my own little tweaks.
Pressure Cooker Peperoncini Pot Roast (aka Mississippi Pot Roast)
Here's what you'll need to make it:
- 5-6 pounds of beef chuck roast
- 1 stick (4 oz) salted butter
- 16 oz. fresh sliced mushrooms
- 1 (16 oz.) jar of Mezzetta Peperoncinis
- 6 oz. water
First, as you can see, I use a lot of meat! In fact, I almost double the size of the roast from the recipe Amy shared with me. Of course I have to with 8 of us in the house ... and 6 of those people are big-appetite boys and men. But if you don't have a big family, this is also an amazing recipe to take to a potluck or share witih a crowd!
Second, the other big change is that I use a whole jar of Mezzetta Peperoncinis. Of course I needed more flavor for the bigger roast! But also, I love getting to the bottom of the jar so there’s no waste (or forgotten jars of peppers sitting in my frig for weeks or months!)
Finally... are you ready for the recipe? If your family loves pot roasts, they're going to go nuts for this one!! Serve it over rice or mashed potatoes - that's how we do it! Or it would also be delish shredded and served as a sandwich!
