In a shallow dish or pie plate, combine flour, garlic powder, onion powder, fine sea salt and black pepper.
Dredge cube steaks in flour mixture, gently shaking off excess.
In a large skillet, preferably cast iron, heat over medium-high heat. When hot, add oil for 1 minute.
Add cube steaks to the skillet. If working with a smaller skillet, you might have to work in batches. Do not crowd the steak.
Cook for 2-3 minutes on each side or until browned. Remove to a plate and set aside.
In the same skillet, add butter, white onion and sliced mushrooms. Saute until starting to soften, about 3-4 minutes.
Using a whisk, add dry gravy mix, making somewhat of a paste and scraping the dried bits off the bottom of the pan.
Stir in beef broth until smooth. Taste test and add additional salt or pepper, if needed.
Add cube steaks back to the skillet, spooning sauce over the top. Cook for another 1-2 minutes so they can reheat and sauce can thicken. Serve immediately over rice, buttered noodles or mashed potatoes.
