# How to Make It:

01 - Preheat oven to 400°F.

03 - While potatoes cook, heat olive oil in a large skillet over medium heat. Add onion, carrots, and celery; sauté 5-7 minutes until softened. Add garlic and cook 1 minute more.
04 - Stir in lentils, vegetable broth, diced tomatoes, tomato paste, thyme, rosemary, and smoked paprika. Bring to a boil, reduce heat, cover, and simmer 20-25 minutes until lentils are tender and mixture thickens. Add water if needed.
05 - Stir in peas, and season with salt and pepper. Remove from heat.
06 - Transfer lentil filling to a large baking dish. Spoon mashed sweet potatoes over the top, spreading evenly.
07 - Drizzle with a little olive oil if desired. Bake for 20 minutes, or until topping is slightly golden.

# Expert Advice:

01 -
  • The combination of naturally sweet mashed potatoes and savory, herb-infused lentils creates the perfect balance of flavors
  • This recipe has saved me countless times when I need to feed a crowd with different dietary restrictions
02 -
  • The most common mistake is under-seasoning the mashed sweet potatoes, so taste them repeatedly and remember they can handle more salt than you might think
  • Letting the assembled pie rest for those 5 minutes after baking is essential, otherwise the filling will be too loose and slide everywhere when you try to serve it
03 -
  • Rinse your lentils thoroughly until the water runs clear to remove any dust or debris that could make the filling gritty
  • If the sweet potato topping seems too thick to spread easily, fold in another tablespoon of plant-based milk
