I love my slow cooker, and as much as I love my Instant Pot, I believe that they cannot be 100% interchangeable when it comes to recipe outcomes. However, after forgetting to start my Italian Pot Roast yesterday morning, I decided to adapt it to the IP and see what would happen. With a couple of changes, it came out tender and delicious.
And it only takes about 7 minutes to throw together. While the cook time is a little longer than many IP recipes, I think trying to shorten it would result in meat that is not as tender as it should be.
The Heathens ate it over some egg noodles, and I did not have to pull together a more labor-intensive Plan-B dinner. Sounds like everyone is a winner, and sanity reigned for another day. Can’t beat that with a stick.

Italian Pot Roast
Notes
- 3-lb chuck roast
- 2 TBS canola oil
- 8 ounces sliced baby bella mushrooms
- 1 large onion, thinly sliced
- 1 tsp. black pepper
- 1 envelope dry onion soup mix
- 1 (14-ounce) can beef broth
- 1 (8-ounce) can tomato sauce
- 3 TBS tomato paste
- 1 tsp. Italian seasoning
- 3 TBS cornstarch
-
- Season roast with pepper on all sides. Set Instant Pot to Sauté setting and let it get hot. Add the canola oil and brown the roast on all sides (this can be a little awkward but it can be done).
- Remove roast from IP and set aside. Add mushrooms and onions to the IP, stirring well so they can pick up any browned bits from the bottom of the IP. Return roast to IP. Top roast with onion soup mix, beef broth and tomato paste.
- Place lid on IP and switch to Manual mode for 70 minutes at high pressure. When cooking is complete, let it release naturally for 5 minutes, then manually release the pressure. Skim as much fat from the top as you feasibly can.
- Switch IP to Sauté mode Add the tomato paste and Italian seasoning. Mix cornstarch with 3 TBS of water and add to the IP, stirring well. Let simmer 5 to 10 minutes until slightly thickened. Shred beef to desired texture. Serve over hot egg noodles and garnish with parsley if you are feeling fancy.
This looks and sounds delicious! Unfortunately I don’t have an instant pot just yet (on next years Christmas list I think). Do you have a link to the recipe for this using the slow cooker?
Reduce the corn starch to 2 Tbs, and cook ok high for 5-6 hours. I have a crockpot that has a safe for stovetop pot so I can still sear the roast in the pot. Also, after adding the paste, seasoning and corn starch, replace lid and cook for 30 more minutes. Hope that helps!
