Step 1

In small bowl, mix together salt, pepper, chili powder, onion powder, and cumin.

Step 2

Generously season both sides of flank steak with spice mixture, making sure to rub spices into steak very well.

Step 3

Add olive oil to Instant Pot and turn on Sauté function. Add flank steak to Instant Pot. If needed, cut flank steak (against the grain) into two large pieces to fit in Instant Pot. Brown flank steak on both sides for approximately 6 minutes total (2-3 minutes per side).

Step 4

After browning flank steak, add beef broth, lime juice, orange juice, and garlic to Instant Pot.

Step 5

Place cilantro and onion on top of flank steak. Secure lid on Instant Pot and set to Manual High Pressure for 20 minutes (for well done steak - see Notes). After 20 minute cook time is up, let pressure naturally release for 10 minutes.

Step 6

Vent to release any remaining pressure and carefully remove lid. Transfer flank steak to cutting board. Slice into thin strips, always cutting against the grain.

Step 7

Top sliced flank steak with additional chopped cilantro if desired and serve.
