In a Gallon Zip lock bag put Flour, Lawrey's Season Salt, and Pepper and shake to combine. Add beef stew chunks and coat.
Heat frying pan or Instant Pot on Saute until Hot. Add oil and add stew meat to brown. Do not over stir. Allow the beef chunks to brown and then turn sides to brown. The bottom of the pan will have bits cooked onto it. This is fine.
Turn off Instant Pot. Remove beef from Instant Pot. Deglaze Instant Pot with beef broth by adding beef broth and allowing the liquid to help lift off the cooked bits left behind.. Scrape bottom of pan so nothing is stuck on the bottom.
Add Beef, whole baby carrots, diced potatoes, diced onion, Garlic, Celery to beef broth. Do NOT Stir
Pour can of Stewed Tomatoes on top, Pour can of Crushed Tomatoes on top. Sprinkle Italian Seasonings. DO NOT STIR.
Set to Manual for 35 minutes and allow a 15 minute Natural Release. Then Quick Release the remaining.
Serve with Cornbread or French Bread
It's Important that you DO NOT Stir the ingredients together. The Pressure Cooker needs thin liquid to create pressure, the beef broth on the bottom of all the ingredients will do this. If you stir, the Pressure Cooker will likely not pressure up.
