Instant Pot Rocky Mountain Roast
This roast is so good! You can use a fresh or frozen solid roast. The recipe doesn’t call for browning the roast. And there are no packets used but there is a lot of flavor. You can make the roast all by itself or you can add in potatoes and carrots to make it a full meal. My family loved this roast dinner and I think you will love it too!
Ingredients/Substitution Ideas
- Beef broth–or water and Better than Bouillon beef base
- Red wine vinegar
- Bay leaf
- Chuck roast–fresh or frozen
- Kosher salt

Steps
Add broth, vinegar and bay leaf into Instant Pot. Add in the chuck roast (I used a frozen chuck roast).
In a bowl whisk together the salt, pepper, thyme, garlic powder, onion powder, parsley, ketchup and Worcestershire.
Spoon the mixture over the top of the roast.
Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 80 minutes for frozen roast or 60 minutes for fresh roast. When time is up let pot sit for a full natural pressure release. Remove the lid.
Move the roast to a cutting board and set aside.
Add the carrots and potatoes into the Instant Pot. Cover Instant Pot and secure the lid. Make sure valve is set to sealing. Set the manual/pressure cook button to 8 minutes. When time is up move valve to venting and remove the lid.
Stir cornstarch together with 3 Tbsp water until smooth. Turn Instant Pot to saute setting. Stir the slurry into the pot to thicken the gravy.
Slice the roast and serve with the potatoes, carrots and gravy. (I stirred the cut up roast into the pot with everything else).
Notes/Tips
- If you’d like, skip the peeling and cutting…use baby carrots instead of regular carrots.
- Make sure to salt and pepper to taste.
- Want to add more depth of flavor? Try browning the roast in a little oil before pressure cooking or slow cooking.
- You can use blade roast, cross-rib/shoulder roast, rump roast, bottom roast, and boneless chuck roast. My roast was trimmed of excess fat.
- The second time pressure cooking goes really quick because the pot is already warmed up so it comes to pressure fast.
- This recipe can be gluten-free if you use gluten free Worcestershire sauce.
- This recipe is dairy-free.
- I used my 6 quart Instant Pot*. You can also make this in an 8 quart pot.
- Store leftovers in an airtight container* in the refrigerator for up to 5 days or in the freezer for up to 3 months.
- Other recipes you can make with carrots are Instant Pot Homestyle Chicken And Vegetables and Instant Pot Broccoli Cheddar Soup.

This was the best. Thank you for this quick,easy and delicious recipe.
Thank you so much Patsy!
Hi Karen! Was just surfing Pinterest to find an instant pot recipe for my frozen sirloin tip roast. I believe it’s much leaner than a chuck roast, so wondering if this recipe will work with that and if I should make any adjustments. If I don’t hear back from you I’m going to give it a try, but thought I would see if you happen to be on today. 😉😊
Totally delicious and SO amazingly easy! I love that it comes out just as tender from frozen as fresh. Thank you!
It is one of the best things about the instant pot that you can throw in meats frozen!
I couldn’t find my roast beef recipe so I just wing it, and it came out super great. After making it I see you just came out with this recipe which is exactly the ingredients I used. So now I know I was on the right track! I substituted some potatoes with yams and turnips for lower carbs. Than I used potato starch as an thicker as I think it gives a great potato soup like flavor. Great recipe!
Great minds think alike!
Hi Karen. I’m always looking for pork roast recipes. Would this work with pork?
