Can I make Hearty Lentil and Sweet Potato Shepherd’s Pie ahead?

How do I know it is done?

Follow the recipe timing, then check the main ingredient for tenderness, bubbling, browning, or safe doneness before serving.

Can I adjust the seasoning?

Ingredients for Hearty Lentil and Sweet Potato Shepherd’s Pie

Instructions

Preheat your oven to 375°F (190°C).
Place the peeled and cubed sweet potatoes in a pot with enough water to cover them. Bring to a boil and cook until tender, about 15-20 minutes.
While the sweet potatoes cook, heat olive oil in a large oven-safe skillet or Dutch oven over medium heat.
Add the chopped onion and sauté for 3-4 minutes until softened.
Stir in the garlic, carrots, celery, and mushrooms. Cook for another 5-7 minutes until the vegetables release their moisture and start to brown slightly.
Add the rinsed lentils, tomato paste, smoked paprika, dried thyme, rosemary, and bay leaf. Stir to coat the vegetables and lentils with the spices and tomato paste.
Pour in the vegetable broth, bring to a simmer, then reduce heat to low. Cover and cook until lentils are tender and most of the liquid has been absorbed, about 25 minutes. Stir occasionally to prevent sticking.
Remove the bay leaf. Season the lentil-vegetable mixture generously with salt and black pepper.
Drain the cooked sweet potatoes and return them to the pot. Mash with nutritional yeast (if using) and almond milk until smooth and creamy. Season with salt and pepper to taste.
Spread the lentil mixture evenly in the bottom of the skillet or Dutch oven.
Evenly spoon and spread the mashed sweet potatoes on top, smoothing with a spatula.
Place the skillet in the preheated oven and bake uncovered for 15 minutes, until the topping starts to lightly brown and the edges bubble.
Remove from the oven and let cool slightly. Garnish with chopped fresh parsley before serving.
Serve warm as a hearty, comforting main dish. Store leftovers in airtight containers in the refrigerator for up to 4 days, or freeze for up to 3 months.
