First, season both sides of your steak with Tony's, garlic powder, and onion powder.
Then, pour 1/4 cup of oil into the instant pot with the sauté setting on.
Next, place the seasoned steak in a single layer on the bottom of the instant pot and brown.
When the first side has a nice sear, turn the steak over and brown the other side.
Take the steak out of the instant pot and add another batch of steak to the instant pot to brown. Add more oil if needed. (1/4 cup)
Once all the steak has been browned, place the meat in the lid of the Instant Pot.
Then, add your chopped onion to the instant pot and scrape up all of the brown bits off the bottom with the onion. Cook until just soft.
Then, remove the onion from the instant pot and place it in the lid with the browned steak.
Add 1/4 cup of oil to the instant pot.
Next, add 4 tablespoons of flour to the oil and stir.
Cook the flour and oil mixture (roux) until it becomes dark. (This doesn't take a long time so don't walk away.)
Add 8 cups of water to the roux and stir.
After the water has been incorporated into the roux, add the cream of mushroom soup.
Then, add back all of your browned steak and onions.
Sprinkle beef powder into your mixture and stir.
Finally, put the lid on the instant pot and set it for a cook time of 6-8 hours. (the longer the better)
After cooking all day, it's time to taste your seasonings, add the pepper and anything else that it may need, and enjoy it with your favorite sides!
