Cut the celery, carrots, and potatoes into chunky bite size pieces and put them in a bowl. Chop the onion and put it in a separate bowl. Cut the beef into bite size pieces.
Put your instant pot on the sauté setting and add the cooking oil, beef chunks, onions, minced garlic, salt, pepper, and Worcestershire sauce. Stir and sear the meat until it is browned and the onions are softened. Meat does not have to be cooked through. Do not drain.
Add the potatoes, carrots, celery, (peas if desired), tomato soup and beef broth. Stir together.
Seal the top of your instant pot. Close the release valve. Press beef/stew setting.
Once it has finished let it slow release for 5-10 minutes then quick release.
Stir, check that potatoes and carrots for done, taste to see if you need more salt or pepper.
This stew can cook in a crock pot on high for 3-4 hours or on low for 7-8 hours. It can cook on stovetop on medium low for 40-45 minutes stirring often and checking the veggies for doneness.
Serve with your favorite rolls or bread.
