Set the Instant Pot to sauté on high heat, then add the olive oil and butter.
2
Cut the beef chuck into large cubes and season with salt, garlic powder, onion powder, paprika, and black pepper.
3
Once the butter has melted, add half of the beef cubes to the Instant Pot and sear on each side until browned. Remove the seared beef from the pot and set aside on a plate.
4
Repeat the searing process with the remaining beef cubes and transfer them to the plate with the other seared beef.
5
Pour about 1/4 cup of the beef broth into the Instant Pot and use a wooden spoon to deglaze, scraping any browned bits from the bottom.
6
Turn the Instant Pot off, then add the seared beef with any collected juices, Worcestershire sauce, and the remaining beef broth.
7
Secure the lid on the Instant Pot and set the valve to sealing. Cook on manual high pressure for 45 minutes.
8
After the timer goes off, allow the Instant Pot to naturally release pressure for 10 minutes before manually releasing the remaining pressure.
9
Open the lid, shred the beef, and set the Instant Pot to sauté on low heat.
10
Add the fresh egg noodles and cook for 10 minutes or until the noodles are tender.
11
In a small bowl, whisk together the cornstarch and cold water to create a slurry. Pour the cornstarch mixture into the Instant Pot while it's still in sauté mode.
12
Turn off the Instant Pot and serve the beef and noodles immediately on their own or alongside a side dish of your choice.
