This AIP and Paleo Traditional Shepherd's Pie recipe is the ultimate comfort food.
Preheat the oven to 350 degrees F.
Prepare all of the vegetables including the sweet potatoes. Heat avocado oil over medium heat in a large pan. Saute the garlic and onion for 3 minutes. Add in the celery, carrots, apple cider vinegar, spices and bone broth. Cook for 8 minutes and then set aside.
Brown the ground beef and season with salt. Then mix the cooked vegetables in with the cooked beef.
While the beef is cooking bring the chopped sweet potatoes to a boil over high heat. Cook until fork tender.
Drain the sweet potatoes and using an electric mixer blend the sweet potatoes with thyme, lard and salt until smooth.
Spoon the meat and vegetable mixture into a 9 x 13 glass baking dish. Then top the mixture with the sweet potato topping by spooning it on top and then smoothing the top with the back of a spoon.
Bake uncovered for 30-40 minutes until slightly golden and bubbling.
Store in a glass dish in the fridge for up to 4 days.
