  • 3 Tbsp olive oil
  • 2 lbs ground beef (I usually use 85/15)
  • 3 Tbsp unsalted butter
  • 1 large yellow onion, diced
  • 2 - 3 carrots, peeled and diced
  • 12 - 16 oz cremini (baby portobello) mushrooms, cleaned and quartered
  • 4 cloves garlic, minced
  • 1 1/2 tsp dried oregano
  • 1 Tbsp kosher salt , divided
  • 3 - 6 Tbsp tomato paste (I normally use around 4)
  • 1/2 - 1 cup beef stock
  • 1 tsp Worcestershire sauce
  • 1/2 tsp black pepper, more or less to taste
  • 3 - 4 cups mashed potatoes
  • 1/3 cup grated/shredded Parmesan cheese
  • 1 1/2 Tbsp butter, cut into small pieces
  • minced fresh parsley, for garnish


  • Preheat oven to 375 F degrees.  Heat a BIG oven safe skillet over MED heat.  Add oil and ground beef and cook about 4 minutes, or until cooked through, breaking it up into small crumbles as it cooks. Once browned, transfer to a plate.  If needed, drain excess grease before adding the beef to a plate.  
  • Add butter to same skillet. Once melted, add onion, carrots, mushrooms, garlic, dried oregano, and 1/2 the salt.  Cook, stirring occasionally, about 8-10 minutes.  
  • Add in tomato paste, stirring to combine, and cook 5-7 minutes, until tomato paste is a dark, brick red color (this really brings out the tomato flavor).  
  • Return cooked ground beef to the skillet, then stir in beef stock, Worcestershire sauce remaining salt, and black pepper.  Simmer for a few minutes, until mixture is slightly thickened.
  • Top with mashed potatoes (see recipe notes section), and Parmesan cheese.  Use a fork to rough up the top of the potatoes, then dot with the butter pieces.
  • Bake 40-45 minutes, until bubbly and potatoes are browned.  Let cool 5-10 minutes before serving.  Sprinkle with minced fresh parsley and enjoy!


Mashed Potato Options:
  1. Use leftover mashed potatoes (these horseradish mashed potatoes work perfectly!).
  2. Use your slow cooker to make the mashed potatoes (like this version).
  3. Use pre-made or instant potatoes - not the best option, but works in a pinch.
  4. Alternately, in a separate pot, make your own traditional mashed potatoes:
    • 5-6 russet potatoes, peeled and cut into chunks
    • 4 Tbsp softened butter
    • 1/2 cup milk (possibly slightly more, depending on your tastes)
    • Sprinkle of Parmesan cheese
    • Salt and pepper, to taste
      • Boil potatoes 15 minutes, or until fork tender, then drain.  Return to hot pot, add butter and mash.  Add milk and cheese, stirring/mashing to combine.  Season to taste.
*** If you don't have an oven safe skillet, complete recipe through step 4, then transfer to a greased 3 qt baking dish, then continue with recipe, starting at step 5.
