Ingredients

  • 2 cups refrigerated mashed potatoes
  • ¾ cup shredded cheese {divided}
  • 1 pound lean ground beef {I used 93/7}
  • ¼ cup onion {diced}
  • 2 cloves garlic {minced}
  • 1 ¼ cups frozen vegetables {I used peas & carrots}
  • 2 tablespoon tomato paste
  • 1 tablespoon worcestershire sauce
  • ½ tablespoon steak seasoning
  • 1 package brown gravy mix {0.87 ounces}
  • 1 cup water

Instructions

  • Preheat the oven to 375 degrees.  In a medium bowl combine 1/2 cup of shredded cheese with mashed potatoes. Stir until it is evenly incorporated. Set aside.
  • In a 12" cast iron skillet, cook ground beef and onion over medium-high heat, stirring occasionally, until meat is cooked through, drain.  Add minced garlic to the drained meat and cook for an additional 30 seconds.
  • Reduce heat to medium, add frozen vegetables, tomato paste, worcestershire sauce and steak seasoning.  Stir to combine and cook 1-2 minutes, stirring frequently.  Next, add brown gravy packet and water. Stir until well blended and cook for an additional 2-3 minutes or until it begins to thicken.
  • Remove from heat and spread refrigerated mashed potato mixture over the beef mixture.  Top with remaining cheese and bake for 20- 25 minutes or until heated through. Store leftovers in the refrigerator for up to 3 days.

Notes

  • If you don't have a cast iron skillet, use an oven proof skillet. A skillet that can withstand the oven works great in place of cast iron.
  • Use ground turkey or chicken instead of ground beef.
  • Brown the ground beef in the same pan you bake it in. This will give the pie amazing flavor and keep it one dish.
  • If you don't have a packet of brown gravy use a turkey gravy packet with beef stock instead of water.
  • Instead of store bought mashed potatoes, add instant potatoes, mashed sweet potatoes or cauliflower mash.
  • Change up the frozen vegetables to whatever it is that you prefer. You could also add your favorite fresh vegetables that have been steamed. OR make it a vegetarian dish by substituting the hamburger for hearty vegetables like mushrooms.
  • Add an upscale touch by piping the mashed potatoes to the top. This creates a wonderful texture and beautiful finished look.
  • Top with chopped parsley or chives. Adding chopped fresh herbs to the top of the finished skillet dinner will add color and great flavor.
