I never truly appreciated a Shepherd’s Pie until I went to culinary school. Which is probably not something you would expect a culinary student to say. Why would you need to go to culinary school to appreciate something as simple as a meat pie? But hear me out!

#1 – Shep’s is perfect for a crowd.

The school I attended served a different menu every night from Tuesday-Saturday that was run mainly by the second year students with the first years assisting with dishes and serving. The amount of work that would go into each service from the staff and students was truly astronomical. Every single night the entire team would sit together for family meal before service, which was more often than not a stew or Shepherd’s Pie. Did I get sick of it? ABSOLUTELY. But there are very few things that are so inherently versatile, can use up a variety of ingredients to prevent waste, provide sufficient nutrition and can feed a large crowd in as short of a time as Shepherd’s Pie.

#2 – You can show off your cooking skills.

Shepherd’s Pie is also the perfect place for you to show off your cooking skills. Searing the meat creates fond, those crispy little bits on the bottom of the pan, and when you deglaze with wine or stock you are lifting them up off the bottom and into the dish. Then you continue to add flavour by adding your ingredients in stages. After the meat is browned and the vegetables have softened you can pop in some tomato paste, and since there isn’t currently any liquid in the pan the sugars can caramelize and the flavour will deepen. Then comes the wine, which may not be included in your standard recipe but it is here! By adding it on its own and reducing it you are removing the alcohol and leaving behind the flavour. Finally, there’s the broth, which is added last and bubbles away until the meat is tender, the vegetables are cooked and the flavour is rich and savoury.

And let’s not forget the mashed potatoes! Maybe it’s because I come from a family who notoriously undercooks the potatoes that these are so important to me – but the potatoes need to be creamy. Not loose. Not Claggy. Making mashed potatoes may seem easy peasy, but there are a plethora of ways you can fuck up a potato.

Here’s to making better mashed potatoes.

These are simple things you can do to improve your mash:

  • Use Yukon golds.
  • Rinse the diced potatoes. Cover them in water, give them a swish, drain and cover them again.
  • Make sure there are a few inches more water than potatoes.
  • Season your water generously with salt.
  • Use a potato ricer.
  • Mix in the butter BEFORE adding the milk.
  • Add your milk in stages. You don’t want potato soup.

Ingredients

  • 1 lb Ground Beef (I used ground sirloin)
  • 2 large Carrots (peeled, small dice)
  • 3 Shallots (small dice)
  • 2 cloves Garlic (minced)
  • 2 sprigs Thyme (picked)
  • 2/3 cup Red Wine
  • 1/4 cup Tomato Paste
  • 2 cups Beef Broth (no salt added)
  • 2 tbsp Parsley (finely chopped)
  • 1 tbsp Flour
  • 1 tbsp Butter (room temperture)
  • Salt
  • Pepper

Mustard Spiked Mashed Potatoes

  • 1.5 lbs Yukon Gold Potatoes (peeled, 3/4" dice, weight after processing)
  • 2 tbsp Butter
  • 1/2 cup Milk
  • 2 tsp Dijon Mustard
  • Salt

Instructions

  • Preheat the oven to 375F.
  • Preheat your dutch oven over medium-high then add the ground beef, season with salt and allow to sit undisturbed until it easily releases from the pan, 4-5 minutes.
    Add the carrots and shallots then begin breaking up the meat and stirring until the mince is fully cooked, an additional 4-5 minutes.
    Add the garlic and stir for one minute.
    Note: Depending on the fat content of your ground beef you may need to remove excess fat from the pan.
  • Add the tomato paste and stir constantly until it becomes a deep red and starts to stick to the bottom of the pan. Deglaze with the red wine and cook until it has reduced completely.
  • Add the beef broth and thyme then season with salt and bring to a simmer, stirring occasionally until reduced to about 1/2-3/4 cup.
    Meanwhile, mash together the flour and butter until it becomes a paste, this is called beurre manie.
  • When the broth is finished reducing add the beurre manie and chopped parsley then stir until it has completely mixed in and the sauce is thick and glossy. If using a baking dish transfer the meat mixture to the baking dish now.

Mustard Spiked Mashed Potatoes

  • While the meat sauce is cooking add the diced potatoes to a pot and cover the in cold water. Swish them around until the water is cloudy then drain and cover with fresh water making sure the water is at least 2" above the potatoes.
    Season the water with salt and add a sprig of thyme if you would like and bring to a boil. Cook until tender, this will take 12-15 minutes.
  • Drain the cooked potatoes and then rice them. Fold in the butter before adding the milk in at least three additions, stirring to combine after each. Fold in the dijon and season to taste with salt.

Assembly and Baking

  • Spread the mashed potatoes in an even layer over the meat sauce. If you like the topping a little crispy you can add swoops and swirls, the more texture the top has the more little crispy bits you will get!
  • Bake for 20 minutes, until the top is golden and there is bubbling around the edges. Allow to cool for 15 minutes before serving.
