Ingredients for Casserole Layered Sweet Potato, Lentil, and Spinach Pie

Instructions

Preheat oven to 375°F (190°C).
Place the chopped sweet potatoes in a large pot and cover with water. Bring to a boil and cook until tender, about 15 minutes. Drain and mash with lemon juice and nutritional yeast if using. Set aside.
While sweet potatoes cook, heat olive oil in a medium skillet over medium heat. Add diced onion and sauté until softened, about 5 minutes.
Add minced garlic, smoked paprika, cumin, thyme, salt, and pepper. Cook for 1 more minute until fragrant.
Add rinsed lentils and vegetable broth to the skillet. Bring to a boil, then reduce heat and simmer, covered, for 20-25 minutes or until lentils are tender and liquid is mostly absorbed.
Stir chopped spinach into the cooked lentils and cook just until wilted, about 2 minutes. Adjust seasoning as needed.
In a 9x9-inch casserole dish, spread the lentil-spinach mixture evenly on the bottom.
Layer the mashed sweet potatoes evenly over the lentils.
Bake uncovered for 20-25 minutes until the top is lightly golden and heated through.
Remove from oven and let rest for 5 minutes before serving.
Garnish with fresh parsley or chives if desired. Serve warm.
