This Lentil Sweet Potato Shepherd’s Pie is quite possibly the most hearty and comforting vegetarian meal there ever was. A flavorful lentil stew is blanketed by a layer of mashed sweet potatoes and garnished with fresh thyme.
Preheat oven to 375 degrees. Separate flesh of sweet potatoes from skins and place in a medium-sized bowl. Discard skins. Mash together sweet potato with butter, milk and salt (I used an immersion blender to ensure smoothness). Set aside.
Heat olive oil in a pot over medium heat. Add diced onions and carrots and cook until onions are translucent about 5-7 minutes. Add minced garlic and cook for another minute.
Add cooked lentils, broth and Worcester sauce to the pot and bring to a simmer. Add spinach, thyme, bay leaf, salt and pepper and simmer until broth is absorbed. Discard bay leaf.
