Season flour with salt and pepper in a shallow dish. Dredge steak through the flour. Heat 1 tbsp. of oil in the pot of the Instant Pot using the sauté function and sear the steak just until it's browned on each side (it does not have to be cooked through at this point). Put the steak on a separate plate and set aside.

Add an additional 1 tbsp. oil to Instant Pot. Sauté onion for 4-5 minutes, then add garlic, tomatoes, paprika, Worcestershire sauce, and sage. Turn off the sauté function.

Change function to manual on high pressure. Add steak back to the pot and cook on high pressure for 12-15 minutes (depending on thickness, use 15 minutes for thicker steaks). Use the quick-release valve to allow to depressurize. Serve with your favorite sides.
