The Best Healthy Shepherd's Pie Recipe

Preheat oven to 425 degrees.
In a medium or large pot, fill halfway with water and bring to a boil. Add cauliflower and cook until cauliflower is soft and easily pierced with a fork. Depending on how small you cut your cauliflower, this could take between 10-15 minutes. Drain the water once done cooking.
While the cauliflower boils, start the filling. In a large pan over medium heat, add olive oil and the ground beef. Season with 1 tsp. salt, thyme and rosemary. Sauté and break up the meat until fully cooked.
Once meat is cooked, add onions, carrot, garlic and mushrooms. Sauté for 5-7 minutes.
Add tomato paste, bone broth and Worcestershire sauce. Turn heat to medium low and simmer for 10-15 minutes.
While the meat simmers, finish the topping. Add butter, parmesan and a heavy pinch of salt to cauliflower. Mash with a potato masher until slightly creamy.
In a large baking dish or 4 individual small baking dishes, add the meat and veggie filling. If using the individual baking dishes, evenly split the filling between each of the dishes.
Top the meat with the mashed cauliflower. If using individual baking dishes, split the mashed cauliflower evenly between each dish.
Bake for 25 minutes. Allow to cool for 10 minutes before eating.
