I added some onion and carrots at the bottom of my Instant Pot and mashed them when done into the gravy with a little corn starch slurry. I also paired it with some mashed sweet potato w/ brown sugar butter and coconut milk and the sweet paired with the Savory from this sauce and beef was delicious. I was worried that I should have gone with Regular Mashed Potato like the pictures, but I was So Happy.

This is a wonderfully delicious recipe as is. So easy and so scrumptious! I will make this again and add it to the dinner repertoire.
Kevin Branch
We loved this! It was tender and flavorful. I didn’t have peperoncini so I used green chiles. I made my own onion soup mix also. I will definitely make this again.

But when you print the recipe, the subscription ad prints over the directions!

This was great!

I had to make a couple of substitutions and made a few careless mistakes. I didn’t have pepperoncini so I used a jar of sliced jalapenos with the juice, I didn’t have onion soup mix but used what I always have on hand, vegetable soup mix – I completely forgot the butter until the roast was almost cooked so didn’t use it at all. I did sear the 6 chunks I cut up of the 5 pound roast and then added all the other ingredients. It was absolutely delicious – a little too spicy for some but that was because I used jalapenos. The meat was super tender and moist and I will definitely make again without the butter. Thanks so much for a great and easy recipe! I’m rating only 4 stars because of my mistakes and substitutions – I’m pretty sure the butter takes this dish of the charts – but I think I’ll continue to make it without.

I cooked for 1 hour 10 minutes instead of 110 minutes. It was well cooked and tender. I used Pickled Vidalia Onion Strips in place of the pepperoncini peppers. I seared the beef first. I used 1 envelope gravy mix combined with one cup water and 1 cup beef bullion. I sliced the butter to distribute it more evenly. The roast was still frozen mid-afternoon, and by dinner time it was tender with a tasty au jus.

I used the drippings to make a gravy, shredded the beef and served it over egg noodles. EVERYONE loved it.

Followed recipe to the T. Came out delicious. Definitely recommend this recipe.
Paul Young
I used sliced pepperonis and it was great! Everyone got some pepperoni (and their wonderful flavor) with each bite! This is definitely part of the meal rotation from now on.
Robert Davis
Mostly followed the recipe, except browned the meat first using saute function. The Au Jus is delicious, used it for french dip sandwiches a few days later.

The flavor of this roast was amazing and so tender! I didn’t have a packet of ranch mix so I substituted with 3 tablespoons of ranch dressing. I also added 1 red onion thin sliced like another reviewer suggested as well as seared the roast on both sides prior to adding the rest of the ingredients to the pot. We made mashed potatoes to go with this and made a gravy using the broth from the roast. It also reheated really well which was great! For leftovers we made a french dip style sandwich which was also awesome. Will definitely be making this again.
Nicole Stewart
I made it exactly as the recipe was written, in an Instant Pot. I think it was cooked too long as the meat was dry.
Martha Williams
This was GOOD! I used this as a base to what I wanted to do with my instant pot. The peppercinis add so much needed flavor but I got a little out of control adding the juice – so beware and control the pour!!! Ours in probably too spicy for our lil toddler man who is two years old so more for us haha. It was done in 2 hours like the recipe says and it was so tender. I seared the roast using sautée method on my instapot first and a little bacon grease. I also used two gravy mixes at the beginning of the recipe mixed with 2 cups water (instead of boullion or beef broth). I also had italian packet instead of onion soup mix. I added onion and carrots besides the peppericinins on the top. Definitely going to be a staple in my instant pot recipe book!!! So good.
Mr. Isaac Gonzales
I added carrots, cut into larger than normal chunks, and they had so much flavor! Two thumbs up from both me and hubs!
Taylor Singh DDS
This is wonderful! Flavorful and juicy, made just as in the recipe. Will definitely make again.
James Jones
I used Oxo Beef rather than onion soup mix but added slivered red onion. The result was wonderful.

Everyone in my family absolutely loved this. It was so tender and moist and the flavor was wonderful. Will definitely make this again.
Brian Campos
Substitute hot pepper rings for pepperocini. Makes a fabulous French Dip (lots of broth). A great way to use leftover roast is to cook noodles half way, drain, put back in pan. Put frozen peas on top. Add heated roast and plenty of broth. Cover and cook on low stirring once until noodles are done.
Joseph Robinson
I love this recipe! So easy and I love putting the meat over rice! Definitely would recommend this recipe to anyone! Favorite meal ever!
