Add the flour, salt, and pepper to a Ziploc bag. Shake to combine. Add the cut up meat to the bag. Shake to coat the meat.
Press SAUTÉ button. When it reads HOT, add oil. Start browning the meat on both sides, in batches. Don’t crowd meat. Save the flour that is left in the bag.
Once the meat is browned, add a couple of tablespoons of beef broth to the pot to deglaze the brown bits. Add onions and garlic and sauté until tender.
Cancel SAUTÉ function; return meat to the pot, juice and all. Sprinkle remaining flour from the bag over the top of the meat. Add the broth and stir.
