If not already diced, dice your beef stewing steak and place it into the Instant Pot. Peel and dice your vegetables and add it to the Instant Pot too.
Place the Instant Pot on the sauté setting and with a tablespoon of olive oil sauté it for a minute or two.
Cancel the sauté, and place 500ml of beef stock into the Instant Pot. Place the lid on the Instant Pot, set the valve to sealing and cook for 50 minutes.
Whilst the beef is cooking make your shortcrust pastry. Then peel and dice your potatoes into roast potato shapes.
When the Instant Pot beeps, drain the liquid from the Instant Pot and then add some gravy granules to the Instant Pot among the beef and vegetables. Add a little liquid at a time until you have a medium to thick beef gravy.
Add the seasoning and give it one last stir.
Fill a pie dish with homemade steak pie filling. Then layer your shortcrust pastry on top. Add some egg wash and create a couple of slits so that the pie can breathe while cooking.
Bake your pie in the oven for 40 minutes at 180c/360f or until the pastry is golden.
While your pie is cooking make the sides. Place the roast potatoes in the air fryer with 1tsp of olive oil and cook for 10 minutes at 180c/360f. Boil your peas in warm water in a small pan.
10. Finally, add a little extra of your stock from earlier with a little bit more of your gravy granules to make a thick gravy to go with your homemade pie.
11. Serve together warm.
