Instructions
Season ribs with salt, pepper and dried oregano. Add oil to instant pot and select saute. Once oil is hot, sear ribs on each side (work in batches). Remove and set aside.
Add onions and garlic and cook for 5 minutes or until onion is tender. Add 1/2 cup beef broth and scrape the bottom of the pan to deglaze.
Add remaining broth and tomato paste and stir well to combine. Add ribs back into the pot and seal the lid shut. Close the pressure release valve and set the instant pot to manual, high pressure for 40 minutes.
When cooking is complete, let pressure naturally release for 20 minutes. Carefully open the and remove the ribs. Cover with foil to keep warm.
Set pot to saute. Once sauce is bubbling and hot, carefully stir in cornstarch slurry (whisked with water) and heat until thickened. Serve!
