The first step to make Instant Pot Sirloin Roast with Mashed Potatoes was to peel and cut the potatoes.  How many depends on how many people you have eating the meal.  I used 6 large potatoes and then placed them in a steamer basket.

The next step was to pour the olive oil into the Instant Pot and turn the Pot to the saute function.  I also sprinkled in a teaspoon of Montreal Steak Spice for extra flavour.

Then I lowered the sirloin roast into the Instant Pot and sprinkled about a half teaspoon of Montreal Steak Spice on top of it.

I seared the sirloin roast on both sides for about 3 minutes a side.

Using a large serving fork I removed the roast to a plate, turned the sauté function off and added in the beef broth.  I made sure to scrape all the brown bits from the bottom of the pot. 

This deglazing step is very important.

After deglazing, I placed the trivet in the Pot and lowered the seared roast on top of it.

I placed the steamer basket full of potatoes on top of the roast.

Then I placed the lid on the Instant Pot, turned the steam release handle to the sealing position and set the Instant Pot to Pressure Cook High for 32 minutes.

When the Instant Pot was done cooking, I allowed it to natural release for 8 minutes.

Then I turned the steam release handle to the venting position to finish with a quick release.

After removing the lid I used oven mitts to carefully remove the steamer basket full of potatoes and the roast.

I also poured off the broth.  To 2 cups of broth I added the two packets of beef gravy mix and placed it in the microwave for 3 minutes stirring once.

While the gravy was cooking I returned the potatoes to the Instant Pot and added some of the remaining broth and 2 tablespoons of margarine.

I used a potato masher to make the mashed potatoes.

Serve the Instant Pot Sirloin Roast with Mashed Potatoes with your favourite vegetable or try Turnip Apple Crumble and Orange Jello Mold for a complete and satisfying meal.  For a bread variation you can make Jumbo Yorkshire Pudding.
