Pat dry the cube steaks with a paper towel, cut them into serving-size pieces if needed, then season with salt, pepper, and Creole seasoning. Set them aside.
In a medium bowl, combine flour, salt, pepper, and garlic and onion powder, and mix well.
Dredge the steaks in the seasoned flour and shake off the excess.
Heat the oil in a cast iron skillet over medium-high heat, then sear the steaks on both sides until golden brown (6-7 minutes per side).
Remove them from the skillet and place them on a plate.
Add onions to the skillet and sauté for 2-3 minutes. Then add the garlic, thyme, oregano, and bay leaf, and continue cooking for 3-5 more minutes, stirring occasionally to prevent it from burning.
Next, add the bell peppers, tomato paste, diced tomatoes, smoked paprika, and Worcestershire sauce. Pour in the broth, cover, and simmer for around 45 minutes or until the meat is tender.
Remove from heat, let it rest for about 10 minutes, and serve hot over rice or mashed potatoes with the gravy.
