My slow cooker beef stew is one of the most popular recipes on What Molly Made, so I figured it was about time to do a guide on how to make a similar recipe in the Instant Pot. We’re using traditional potatoes and veggies for this one and you can even use a frozen roast!
What kind of meat is pot roast?
Pot roast isn’t a specific cut of meat or a specific recipe, but instead it’s more of a cooking method. The best cuts of meat for pot roast are tougher cuts. They’re lean and have a lot of connective tissue so when you cook them low and slow the meat tenderizes and falls apart.
Here are a few cuts of meat that work great for roast in the instant pot:
- Chuck roast (highly recommend this cut for this recipe)
- Bottom round roast
Is a pot roast healthy?
Pot roast is a really healthy meal full of protein, veggies and carbs. This specific recipe is even Whole30 approved meaning it’s gluten free, dairy free and refined sugar free.
How to cook a roast in the Instant Pot:
Start by searing your roast on both sides using the SAUTE button on your Instant Pot. This creates a crust of flavor and seals in the juices.
Add the rest of the ingredients and switch the Instant Pot to MANUAL (high pressure). Cook a 3 pound thawed roast for 60 minutes. It will take time for the Instant Pot to come to pressure then it will start counting down.
Once it’s done, do a natural release (do nothing) for 10 minutes then use a wooden spoon to turn the valve from SEALING to VENTING. Follow the directions below to make the gravy if desired then shred and enjoy!
How long to cook roast in Instant Pot:
For thawed roast: cook your roast for 20 minutes for every pound. For example, a 2 pound roast would be 40 minutes.
For frozen roast: add 10 minutes to the already allotted 20 minutes for every pound of frozen roast. For example, a 2 pound roast would be 60 minutes.
Note: The Instant Pot will take more time to come to pressure if your roast is frozen so give it some time before it starts to count down.
Can you overcook a roast in the pressure cooker?
Yes, just like any cooking method you can overcook a chuck roast in the Instant Pot. Follow the directions based on the size of your roast to know how long to cook it. It should be 20 minutes per pound of thawed roast.
Why is my roast tough?
Both undercooking and overcooking a roast can result in toughness. If it doesn’t fall apart easily it might need more time. If it falls apart but is dry and tough then it may be overcooked.
Can a frozen roast be cooked in an instant pot?
Follow these steps for cooking a frozen pot roast in the Instant Pot:
- Skip the first step of searing the meat.
- Follow the normal directions of adding everything to the pressure cooker.
- Cook on high pressure for 30 minutes per pound (compared to 20 for thawed roast)
Make ahead freezer instructions: Place everything in a large ziplock freezer bag and store in the freezer for up to 3 months. When ready to cook, transfer frozen meal directly to the pressure cooker and cook for 30 minutes per pound of roast.
