Ingredients

Scale
  • 5 medium sweet potatoes, scrubbed
  • 1 cup brown or green lentils, washed and picked over
  • 3/4 cup steel-cut oats
  • 1 bay leaf
  • 1 teaspoon salt
  • 1 tablespoon olive oil
  • 1 pound cremini mushrooms, divided
  • 1 medium yellow onion, chopped

How to Make Lentil, Mushroom & Sweet Potato Shepherd’s Pie

Preparing this dish is a warm experience, one where you’ll feel the ingredients come together softly and perfectly. We’ll roast the sweet potatoes to bring out their natural sweetness while creating a rich filling that beckons for a comforting topping. It’s as simple as the method is rewarding, so grab your apron and let’s create some delicious memories together!

Ingredients You’ll Need

  • 5 medium sweet potatoes, scrubbed
  • 1 cup brown or green lentils, washed and picked over
  • 3/4 cup steel-cut oats
  • 1 bay leaf
  • 1 teaspoon salt
  • 1 tablespoon olive oil
  • 1 pound cremini mushrooms, divided
  • 1 medium yellow onion, chopped
  • 1 large carrot, chopped
  • 1 celery stalk, chopped
  • 1 garlic clove, minced
  • 3/4 cup low-sodium vegetable broth
  • 1/4 cup dry red wine
  • 1 tablespoon tomato paste
  • 1 tablespoon soy sauce or tamari
  • 1 teaspoon smoked paprika
  • 1/4 cup chopped fresh parsley leaves

Step-by-Step Directions

  1. Start by preheating your oven to 400°F (200°C). Roast the sweet potatoes on a baking sheet until soft and tender, about 45 minutes to 1 hour. Let them cool while you move on to the next steps.
  2. In a medium saucepan, combine the lentils, oats, bay leaf, salt, and enough water to cover everything. Bring to a gentle boil and then reduce to a simmer, cooking until the lentils are soft (around 15 to 20 minutes). Discard the bay leaf after cooking and drain the mixture.
  3. While the lentils are cooking, chop half of the cremini mushrooms and quarter the other half. In a large pot, heat the olive oil over medium heat, adding the quartered mushrooms with a pinch of salt. Sauté until they’re beautifully browned, then incorporate the chopped mushrooms, onion, carrot, celery, and garlic. Cook until everything is soft and fragrant, filling your kitchen with a delightful aroma.
  4. Add the lentil-oat mixture to the pot, then stir in the vegetable broth, red wine, tomato paste, soy sauce, smoked paprika, parsley, and some freshly ground pepper. Let it all simmer gently for about 5 minutes, adjusting the seasoning as you like.
  5. Now, reduce the oven temperature to 350°F (175°C). Peel and mash your sweet potatoes, seasoning them lightly with salt and pepper to enhance their natural sweetness.
  6. Spread the hearty lentil mixture into a greased baking dish. Top it generously with the creamy sweet potato mash, spreading it evenly. Bake for about 30 minutes, or until the top is beautifully bubbling and slightly golden.
  7. This pie can be made ahead of time and stored in the fridge for up to 2 days or even frozen for comforting meals later on!
