1️⃣ Prepare the beef mixture:
In a large mixing bowl, combine the ground beef, milk, cracker crumbs, salt, pepper, and finely chopped onion. Mix until all ingredients are well incorporated.

2️⃣ Shape and refrigerate:
Form the mixture into a loaf shape and place it on a plate or in a shallow baking dish. Cover and refrigerate overnight to help the mixture firm up and allow flavors to meld.

3️⃣ Slice and dredge:
The next day, remove the beef loaf from the refrigerator. Slice it into ½-inch thick slices or shape it into patties. Lightly dredge each slice or patty in flour.

4️⃣ Pan-fry the patties:
In a large skillet over medium-high heat, pan-fry the beef slices until they are golden brown on both sides. This will help them hold together and develop a richer flavor.

5️⃣ Assemble and bake:
Transfer the browned beef slices to a baking dish. In a bowl, whisk together the cream of mushroom soup with an equal amount of water or broth until smooth. Pour the soup mixture over the beef patties, making sure they’re evenly coated.

6️⃣ Bake:
Cover the baking dish with foil and bake at 350°F for 1 hour. This will allow the beef to become tender and the sauce to thicken into a savory gravy.

7️⃣ Serve:
Serve the poor man’s steak slices smothered in the mushroom gravy over a bed of mashed potatoes or egg noodles. Enjoy the ultimate in down-home comfort!
