Hamburger Steak Skillet Casserole

Hamburger Steak Skillet Casserole consists of a hearty ground beef mixture in a thick gravy with diced tomatoes covered with a layer of white cheddar mashed potatoes. It tastes like a southern hamburger steak or salisbury steak except in casserole form. It’s like a southern version of Shepherd’s Pie and it is so good.

Next you’ll add garlic, salt, pepper, and dried thyme for seasoning. One quarter cup of flour gets added. It will help thicken the gravy.

Next add a can of diced tomatoes, a can of condensed French onion soup, a cup of beef broth, a tablespoon of red wine vinegar, parsley, and garlic powder. Let this mixture simmer 10 minutes. If needed, you can stop at this point and refrigerate the beef mixture overnight and proceed with the recipe the next day.

Next, boil some peeled and chopped Yukon Gold potatoes until soft. Mash them with butter, milk, and shredded white cheddar cheese. Spread the mashed potatoes on top of the ground beef mixture and broil for 3 to 5 minutes to get everything hot.

This is a hearty and deliciously rich meal that’s best served with a green salad.

  1. This was truly outstanding! It has such a beefy flavor and a thick gravy. My wife and I are low carb so the only change we made was to use mashed cauliflower with lots of cheese, chives, and sour cream. I know that is no comparison to mashed potatoes, but it kept the dish low carb.

  2. This is an awesome dish. Family loved it. I would like to say I could not find any condensed french onion soup so I bought a packet and made my own with the leftover beef broth.

  3. This is incredibly similar to Shepherd’s Pie with added flavors. And if either a cast iron skillet or oven-safe pan can be used, why then is the term skillet in the title?

    It also appears multi-tasking beef browning and the cooking of potatoes can be achieved simultaneously. In my experience and opinion, baking potatoes for mashing yields an improved textured flavor without boiling out nutrients. I do understand the heat impacts from the oven, but if oven is to be used to bake and inevitably brown potatoes under broiler similar to a meringue, baking potatoes is a viable alternative.

  5. If at all possible, please post nutrition ingredients. My 5 year old granddaughter has type 1 diabetes and I have to know how many carbs before she can eat. Thank you so much.
