Ingredients

  • pounds yellow potatoes peeled and quartered
  • 3 tablespoons ghee (or palm shortening for dairy-free) divided
  • 1 teaspoon fine sea salt, plus more as necessary divided
  • ½ teaspoon freshly ground black pepper divided
  • 1 tablespoon olive oil or ghee
  • ½ cup chopped onion, yellow or red
  • 1 pound ground lamb or lean ground beef
  • 1 cup beef broth
  • 1 tablespoon coconut aminos
  • 1 teaspoon arrowroot flour/starch
  • 1 teaspoon dried thyme
  • 1 teaspoon dried rosemary
  • ½ cup frozen peas and carrots not thawed

Instructions

  • Heat the oven to 400°.
  • Add the peeled and quartered potatoes to a saucepan and cover with water (there should be about an inch of water between the potatoes and water's surface). Place over high heat and bring to a boil, then reduce the heat to bring it down to a simmer. Simmer the potatoes for 15 minutes, or until a knife easily slides through.
  • Drain the potatoes, reserving a half cup of the cooking water.
  • Return the potatoes to the saucepan and mash until chunky. Then add the water, 1 tablespoon ghee, ½ teaspoon fine sea salt and ¼ teaspoon black pepper. Keep mashing or whip with a wooden spoon or spatula until blended and fairly smooth. Set aside.
  • Meanwhile, while the potatoes are cooking, add 1 tablespoon olive oil or ghee to a medium, 10" heat-proof skillet and place over medium heat.
  • Once the oil is hot, add the onion and a pinch of salt and sauté, stirring occasionally until soft, about 10 minutes.
  • Add the ground beef or lamb and break it up as it cooks, stirring occasionally, until browned, about 10 minutes.
  • While the onion and meat cook, in a medium mixing bowl, whisk together the beef broth, coconut aminos and arrowroot. Set aside.
  • Once the meat is browned, add the thyme, rosemary, ½ teaspoon fine sea salt and ¼ teaspoon black pepper. Add the ½ cup of frozen peas and carrots and stir everything together. Cook until the peas and carrots are warmed through, about 2-3 minutes, stirring occasionally.
  • Give the broth mixture another whisk then pour it into the skillet and stir everything together. 
  • Turn the heat up to medium high to bring the mixture to a boil, then reduce to a simmer and let it cook until thickened, about 10 minutes.
  • Spread the potatoes on the meat mixture. Distribute 2 tablespoons of ghee in little dabs over the potatoes.
  • Bake until the pie is hot and bubbly around the edges, about 30 minutes. Let rest for at least 10 minutes, then dig in!

Notes

Nutrition note: The nutrition info was calculated using 95% lean ground beef.
Substitutions
  • Per the recipe, you can use either lean ground beef (technically making it a cottage pie) or ground lamb.
    - You can also use ground turkey instead of beef or lamb.
    - You can use ½ cup chopped shallots instead of an onion.
    - You can use one tablespoon fresh chopped thyme instead of dried.
    - You can use ½ tablespoon fresh chopped rosemary instead of dried.
    - You can use chicken broth instead of beef broth.
    - You can use tapioca flour/starch instead of arrowroot.
    - You can use either all frozen peas or all frozen carrots.
Make ahead
The pie can be made up to 5 days in advance. Let it cool before storing in the fridge.
Heat in a 350° oven until hot, about 20-30 minutes.
If you know you're going to make it advance, you might want to transfer the meat mixture to an 8x8" baking dish, top it with the potatoes and bake it like that. Then, once it's baked and cooled, you can store directly in the fridge. (Or, if you're okay putting the cooled skillet in your fridge, that's fine.)
Leftovers can be stored in the fridge for up to 5 days.
Freezer info
Transfer the cooled pie a freezer-safe container, cover tightly with plastic wrap and seal the container.
You can freeze the pie for up to 3 months.
Thaw overnight in the fridge.
Heat in a 350 degree oven until hot, about 20-30 minutes.
