In a large mixing bowl, combine ground beef, diced onion, crumbled saltine crackers, 1 cup milk, 1/4 cup flour, garlic powder, salt, and pepper. Mix thoroughly until well combined.
Shape the mixture into oval or rectangular patties, resembling traditional steak shapes.
Coat each patty lightly with flour, shaking off any excess.
In a large skillet, melt butter over medium-high heat. Brown the patties on both sides, about 3 minutes per side, for added flavor and color. Set aside.
Place the browned patties in a greased 9×13 baking dish. In a separate bowl, mix cream of mushroom soup and 1.5 cups milk until smooth. Pour the gravy sauce over the patties.
Cover the baking dish with foil and bake for 50 minutes. Remove the foil and bake for an additional 10 minutes to thicken the gravy.
Serve this Amish Poor Man’s Steak hot, enjoying the rich, savory flavors that make it a family favorite. Perfect for a cozy dinner on a budget!
